SUPPLEMENTARY INFORMATION:

Background and Explanation of Provisions

This document withdraws §§1.6152-1(a)(1), 1.6654-2(d)(1)(i), 1.6655-1, 1.6655-2, 1.6655-3, 1.6655-4, 1.6655-5, 1.6655-6, and 301.6655-1 in the notice of proposed rulemaking (LR-228-82, 1984-1 C.B. 760) relating to corporate estimated taxes under section 6655 that was published in the Federal Register (49 FR 11186) on March 26, 1984 (referred to as the 1984 proposed regulations). This document also contains new proposed amendments to the Income Tax Regulations (26 CFR Part 1) and the Procedure and Administration Regulations (26 CFR Part 301) relating to corporate estimated taxes under section 6425 and section 6655 of the Internal Revenue Code. The IRS is withdrawing the 1984 proposed regulations because significant changes to the law since 1984 have caused them to become outdated.

These proposed regulations reflect changes to the law made by the Deficit Reduction Act of 1984, Public Law 98-369 (98 Stat. 494), the Superfund Amendments and Reauthorization Act of 1986, Public Law 99-499 (100 Stat. 1613), the Tax Reform Act of 1986, Public Law 99-514 (100 Stat. 2085), the Omnibus Budget Reconciliation Act of 1987, Public Law 100-203 (101 Stat. 1330), the Revenue Act of 1987, Public Law 100-203 (101 Stat. 1330-382), the Omnibus Trade and Competitiveness Act of 1988, Public Law 100-418 (102 Stat. 1107), the Technical and Miscellaneous Revenue Act of 1988, Public Law 100-647 (102 Stat. 3342), the Omnibus Budget Reconciliation Act of 1989, Public Law 101-239 (103 Stat. 2106), the Omnibus Budget Reconciliation Act of 1990, Public Law 101-508 (104 Stat. 1388), the Tax Extension Act of 1991, Public Law 102-227 (105 Stat. 1686), the Act of Feb. 7, 1992, Public Law 102-244 (106 Stat. 3), the Unemployment Compensation Amendments of 1992, Public Law 102-318 (106 Stat. 290), the Omnibus Budget Reconciliation Act of 1993, Public Law 103-66 (107 Stat. 312), the Uruguay Round Agreements Act of 1994, Public Law 103-465 (108 Stat. 4809), the Small Business Job Protection Act of 1996, Public Law 104-188 (110 Stat. 1755), the Taxpayer Relief Act of 1997, Public Law 105-34 (111 Stat. 788), the Ticket to Work and Work Incentives Improvement Act of 1999, Public Law 106-170 (113 Stat. 1860), the Community Renewal Tax Relief Act of 2000, Public Law 106-554 (114 Stat. 2763), the Economic Growth and Tax Relief Reconciliation Act of 2001, Public Law 107-16 (115 Stat. 38), the Jobs and Growth Tax Relief Reconciliation Act of 2003, Public Law 108-27 (117 Stat. 752), and the American Jobs Creation Act of 2004, Public Law 108-357 (118 Stat. 1418).

The existing regulations under section 6655 do not reflect significant changes to the tax law since 1984, most notably the enactment of the economic performance rules under section 461(h). Since the enactment of section 461(h), the determination of when economic performance must occur for taxpayers to take a deduction into account for purposes of computing a quarterly estimated tax payment has been unclear, particularly for taxpayers that compute their quarterly estimated tax payments using an annualization method.

In addition, the IRS and Treasury Department have become aware of techniques employed by taxpayers, particularly those taxpayers computing their estimated tax payments using an annualization method, that reduce, if not eliminate, estimated tax payments for one or more installments for a taxable year. The proposed regulations provide rules that the IRS and Treasury Department believe result in a more accurate reflection of annualized income than methods that taxpayers may currently be employing. For example, the proposed regulations make it clear that taxpayers may not, for any purpose, determine taxable income for an annualization period or an adjusted seasonal installment period as though the period is a short taxable year. The proposed regulations provide specific rules for determining taxable income for any annualization period, including how section 461(h) is to be applied in computing taxable income for any annualization period. For example, with respect to an item of income or gain, the proposed regulations provide that the item must be taken into account in computing annualized taxable income for a particular annualization period if the item is includible in computing taxable income in accordance with section 451 on or before the last day of the annualization period. With respect to an item of deduction, the proposed regulations generally provide that an accrual method taxpayer may take into account a deduction in computing annualized taxable income for a particular annualization period only to the extent the item is incurred under §1.461-1(a)(2) on or before the last day of the annualization period. For purposes of determining whether a deduction may be taken into account by an accrual method taxpayer in determining annualized taxable income for a particular annualization period, the provisions of section 170(a)(2) and §1.170A-11(b) (charitable contributions by accrual method corporations), §1.461-4(d)(6)(ii) (provision of services or property to a taxpayer), §1.461-5 (recurring item exception), and any other provision that has a similar effect are not taken into account in determining whether the item of deduction has been incurred under §1.461-1(a)(2) and is deductible in computing annualized taxable income for an annualization period.

Revenue Ruling 76-450, 1976-2 C.B. 444, provides that state property tax and franchise tax are deductible from the income for an annualization period on the date the taxpayer accrues the taxes under the taxpayer’s method of accounting. Revenue Ruling 76-450 was issued prior to the enactment of section 461(h) and does not take into account the application of the economic performance requirements of section 461(h) for purposes of computing an estimated tax payment using the annualized income installment method. The proposed regulations address the application of section 461(h) for purposes of the annualized income installment method and provide that a taxpayer using an accrual method of accounting cannot take a deduction into account unless the deduction has been incurred under §1.461-1(a)(2) and is otherwise deductible in computing taxable income for the applicable annualization period. As a result of the rules provided in the proposed regulations regarding the application of section 461(h) to the annualized income installment method, Rev. Rul. 76-450 is no longer applicable and will be obsoleted when these regulations are effective.

For purposes of section 404 and the regulations, regardless of the overall method of accounting employed by the taxpayer, the applicable 2-, 3-, 4-, 5-, 6-, 7-, 8-, 9-, 10- or 11-month annualization period shall not be treated as a short taxable year and the rules of section 404 and the regulations shall be applied on the basis of the taxpayer’s taxable year for which estimated tax is being determined. Thus, the determination of whether a payment to an employee is deferred compensation under §1.404(b)-1T shall be made by reference to whether the payment is received by the employee more than a brief period of time after the last day of the taxable year for which estimated tax is being determined, and not the last day of the annualization period. With respect to contributions to qualified plans governed by section 404 and the regulations, in determining whether an item is paid or incurred by the end of an annualization period, economic performance is satisfied only to the extent such item is paid by the last day of the annualization period (without regard to section 404(a)(6)) and does not, in combination with other such items paid during the annualization period, exceed the applicable deduction limit of section 404(a) for the taxable year. For purposes of sections 419 and 419A and the regulations, regardless of the overall method of accounting employed by the taxpayer, the applicable 2-, 3-, 4-, 5-, 6-, 7-, 8-, 9-, 10-, or 11-month annualization period shall not be treated as a short taxable year and the rules of sections 419 and 419A and the regulations shall be applied on the basis of the taxpayer’s taxable year for which estimated tax is being determined. With respect to contributions to a welfare benefit fund governed by sections 419 and 419A and the regulations, in determining whether an item is paid or incurred by the end of an annualization period, economic performance is satisfied only to the extent such item is paid by the last day of the applicable annualization period and does not, in combination with other such items paid during the annualization period, exceed the applicable deduction limit of section 419 for the taxable year.

The proposed regulations provide guidance for annual expenses paid or incurred at the end of the taxable year, or after the end of the taxable year that are deemed paid or incurred during the taxable year. Section 1.6655-2(f)(2)(i) of the proposed regulations provides that if an accrual method taxpayer has a history of incurring a specific item of expense (or paying a specific item of expense, in the case of a cash method taxpayer) that, while attributable to income earned throughout the current taxable year, is not incurred (or paid, in the case of a cash method taxpayer) until the end of the taxable year or after the end of the current taxable year and is deemed incurred (or paid, in the case of a cash method taxpayer) during the current taxable year (taking into account, as applicable, section 170(a)(2) and §1.170A-11(b), section 404(a)(6), §1.461-4(d)(6)(ii), §1.461-5, and any other provision that has a similar effect), then the taxpayer may take into account a proportionate part of the specific item of expense for each annualization period. In such case the taxpayer may take into account a proportionate part of the specific item of expense for each annualization period only if the portion of the annual expense taken into account is determined with reasonable accuracy and the expense is properly deducted by the taxpayer for the current taxable year under the taxpayer’s method of accounting. For purposes of §1.6655-2(f)(2)(i), a taxpayer has a history of incurring or paying a specific item of expense at the end of the taxable year, or after the end of the taxable year that is deemed incurred or paid during the taxable year, if, in each of the two taxable years immediately preceding the current taxable year (or the immediately preceding taxable year if the taxpayer was not in existence for the two preceding taxable years), the taxpayer incurred or paid the specific item of expense at the end of each taxable year, or after the end of each taxable year that was deemed incurred or paid during such taxable year. For purposes of §1.6655-2(f)(2)(i), the term “the end of the taxable year” means the period between and including the 15th and last day of the last month of the taxable year.

The proposed regulations also provide guidance regarding the treatment of specific items for purposes of computing annualized taxable income for an annualization period. For example, net operating loss carryovers must be taken into account in computing an annualized income installment after placing the taxable income for the annualization period on an annualized basis, and section 481(a) adjustments must be recognized ratably over the applicable adjustment period.

Revenue Ruling 67-93, 1967-1 C.B. 366, provides that a taxpayer should deduct a net operating loss (NOL) carryover from the income for an annualization period before annualizing the income for that period. As previously stated, the IRS and Treasury Department believe that it is not appropriate for taxpayers to determine taxable income for an annualization period or an adjusted seasonal installment period as though the period is a short taxable year. As a result, the IRS and Treasury Department now believe that it is a more appropriate reflection of annualized taxable income if a NOL carryover is deducted after annualizing the taxable income for an applicable annualization period or adjusted seasonal installment period. Accordingly, the proposed regulations provide that a taxpayer must annualize taxable income before taking into account a NOL carryover and reduce the annualized amount by the NOL carryover. As a result, Rev. Rul. 67-93 will be obsoleted when these regulations are effective.

In addition, the proposed regulations provide guidance on the amount of depreciation and amortization (depreciation) expense that a taxpayer may take into account for an annualization period. The proposed regulations generally provide that a proportionate amount of a taxpayer’s estimated annual depreciation expense shall be taken into account when determining any annualized income installment for the taxable year. In determining the estimated annual depreciation expense, a taxpayer may take into account purchases, sales or other dispositions, changes in use, depreciation permitted by sections 168(k) and 1400L, and other similar events that, based on all of the relevant information available as of the last day of the annualization period (such as capital spending budgets, financial statement data and projections, or similar reports that provide evidence of the taxpayer’s capital spending plans for the current taxable year), the taxpayer reasonably expects to occur during the taxable year. As an alternative to estimating annual depreciation expense based on events that are reasonably expected to occur, the proposed regulations provide that, in general, a taxpayer may claim for an annualization period at least a proportionate amount of 50 percent of the taxpayer’s estimated depreciation expense for the current taxable year attributable to assets that the taxpayer had in service on the last day of the preceding taxable year, that remain in service on the first day of the current taxable year, and that are subject to the half-year convention. The proposed regulations also provide that an annualization period cannot be treated as a short taxable year, including for purposes of determining the depreciation allowance for such annualization period.

The proposed regulations also provide guidance regarding short taxable years, including the due dates for required installments for a short taxable year (including a taxpayer’s initial taxable year), the computation of such installments, and the applicable percentage of the annual tax due with each installment.

Proposed Effective Date

These regulations are proposed to apply to taxable years beginning after the date that is 30 days after the date the final regulations are published in the Federal Register. Until the final regulations become effective, taxpayers may rely on these proposed rules for taxable years beginning on or after the date this notice of proposed rulemaking is published in the Federal Register, provided, however, that the taxpayer applies all of these proposed rules in determining its required installments.

Special Analyses

It has been determined that this notice of proposed rulemaking is not a significant regulatory action as defined in Executive Order 12866. Therefore, a regulatory assessment is not required. Except with respect to §1.6655-5, which deals with the rules applicable to a short taxable year, it has been determined that section 553(b) of the Administrative Procedure Act (5 U.S.C. chapter 5) does not apply to these regulations, and because these provisions do not impose a collection of information on small businesses, the Regulatory Flexibility Act (5 U.S.C. chapter 6) does not apply. With respect to §1.6655-5, it is hereby certified that this provision of the regulations will not have a significant economic impact on a substantial number of small entities. This certification is based on the fact that not many small businesses are going to be subject to the short taxable year rules because: (1) existing small businesses generally are not targets of mergers and acquisitions, which result in a short taxable year; (2) start-up small businesses with a short taxable year of less than four months do not have to pay estimated taxes; and (3) start-up small businesses with a short taxable year of four months or more are not likely to have taxable income that would be subject to the corporate estimated tax rules. Therefore, a Regulatory Flexibility Analysis under the Regulatory Flexibility Act (5 U.S.C. chapter 6) is not required. Pursuant to section 7805(f) of the Internal Revenue Code, this notice of proposed rulemaking will be submitted to the Chief Counsel for Advocacy of the Small Business Administration for comment on its impact on small businesses.

Comments and Public Hearing

Before these proposed regulations are adopted as final regulations, consideration will be given to any electronic or written comments (a signed original and eight (8) copies) that are submitted timely to the IRS. The IRS and Treasury Department request comments on the clarity of the proposed rules and how they can be made easier to understand. In particular, the IRS and Treasury Department request comments on whether the 52-53 week taxable year rules under §1.6655-2(e) should be simplified. The IRS and Treasury Department also request comments on whether the final regulations should include an additional exception, similar to the exception provided in §1.6655-2(f)(2)(i), that would permit a taxpayer to take into account for an annualization period a proportionate amount of a specific item of expense that is attributable to income earned throughout the current taxable year and is paid or incurred during the taxable year but after the applicable annualization period. If such an exception is appropriate, the IRS and Treasury Department request comments on what specific types of expenses would meet the requirements of the rule, and whether the exception should provide for any additional limitations, such as a requirement that a minimum percentage of the annual amount of the expense be paid or incurred on a particular day during the taxable year. All comments will be available for public inspection and copying.

A public hearing has been scheduled for March 15, 2006, beginning at 10:00 a.m. in the Auditorium of the Internal Revenue Service Building, 1111 Constitution Avenue, NW, Washington, DC. Due to building security procedures, visitors must enter at the Constitution Avenue entrance. In addition, all visitors must present photo identification to enter the building. Because of access restrictions, visitors will not be admitted beyond the immediate entrance area more than 30 minutes before the hearing starts. For information about having your name placed on the building access list to attend the hearing, see the “FOR FURTHER INFORMATION CONTACT” section of this preamble.

The rules of 26 CFR 601.601(a)(3) apply to the hearing. Persons who wish to present oral comments must submit electronic or written comments and an outline of the topics to be discussed and time to be devoted to each topic (a signed original and eight (8) copies) by February 22, 2006. A period of 10 minutes will be allotted to each person for making comments. An agenda showing the scheduling of the speakers will be prepared after the deadline for receiving outlines has passed. Copies of the agenda will be available free of charge at the hearing.

Partial Withdrawal of a Previous Notice of Proposed Rulemaking

Accordingly, under the authority of 26 U.S.C. 7805, §§1.6152-1(a)(1), 1.6654-2(d)(1)(i), 1.6655-1, 1.6655-2, 1.6655-3, 1.6655-4, 1.6655-5, 1.6655-6, and 301.6655-1 in the notice of proposed rulemaking published in the Federal Register on March 26, 1984, (LR-228-82) (49 FR 11186) are withdrawn.

For the purpose of sections 6655(a) through (g), (i), and (j), credit or refund of an adjustment is to be treated as if not made in determining whether there has been any underpayment of estimated income tax and, if there is an underpayment, the period during which the underpayment existed. However, an excessive adjustment under section 6425 shall be taken into account in applying the addition to tax under section 6655(h).

§1.6655-7 Addition to tax on account of excessive adjustment under section 6425.

Par. 7. Sections 1.6655-1, 1.6655-2, and 1.6655-3 are revised to read as follows:

§1.6655-1 Addition to the tax in the case of a corporation.

(a) In general. Section 6655 imposes an addition to the tax under chapter 1 of the Internal Revenue Code in the case of any underpayment of estimated tax by a corporation. An addition to tax due to the underpayment of estimated taxes is determined by applying the underpayment rate established under section 6621 to the amount of the underpayment, for the period of the underpayment. This addition to the tax is in addition to any applicable criminal penalties and is imposed whether or not there was reasonable cause for the underpayment.

(b) Amount of underpayment. The amount of the underpayment for any required installment is the excess of—

(1) The required installment; over

(2) The amount, if any, of the installment paid on or before the last date prescribed for such payment.

(c) Period of the underpayment. The period of the underpayment of any required installment runs from the date the installment was required to be paid to the 15th day of the 3rd month following the close of the taxable year, or to the date such underpayment is paid, whichever is earlier. For purposes of determining the period of the underpayment—

(1) The date prescribed for payment of any installment of estimated tax shall be determined without regard to any extension of time; and

(2) A payment of estimated tax will be credited against unpaid required installments in the order in which such installments are required to be paid.

(d) Amount of required installment. Except as otherwise provided in this section and §§1.6655-2 through 1.6655-7, the amount of any required installment is 25 percent of the lesser of—

(1) 100 percent of the tax shown on the return for the taxable year (or, if no return is filed, 100 percent of the tax for such year); or

(2) 100 percent of the tax shown on the return of the corporation for the preceding taxable year.

(3) Paragraph (d)(2) of this section shall not apply if the preceding taxable year was not a taxable year of 12 months or the corporation did not file a return for such preceding taxable year showing a liability for tax.

(e) Large corporation required to pay 100 percent of current year tax—(1) In general. Except as provided in paragraph (e)(2) of this section, paragraph (d)(2) of this section shall not apply in the case of a large corporation (as defined in §1.6655-4).

(2) May use last year’s tax for first installment. Paragraph (e)(1) of this section shall not apply for purposes of determining the amount of the 1st required installment for any taxable year. Any reduction in such 1st installment by reason of the preceding sentence shall be recaptured by increasing the amount of the next required installment determined under paragraph (d)(1) of this section by the amount of such reduction and, if the next required installment is reduced by use of the annualized income installment method under §1.6655-2 or the adjusted seasonal installment method under §1.6655-3, by increasing subsequent required installments determined under paragraph (d)(1) of this section to the extent that the reduction has not previously been recaptured.

(f) Required installment due dates—(1) Number of required installments. Unless otherwise provided, corporations must make 4 required installments for each taxable year.

(2) Time for payment of installments—(i) Calendar year. In the case of a calendar year taxpayer, the due dates of the required installments are as follows:

1st April 15
2nd June 15
3rd September 15
4th December 15

(ii) Fiscal year. In the case of a taxpayer other than a calendar year taxpayer, the due dates of the required installments are as follows:

1st 15th day of 4th month of the taxable year
2nd 15th day of 6th month of the taxable year
3rd 15th day of 9th month of the taxable year
4th 15th day of 12th month of the taxable year

(iii) Short taxable year. See §1.6655-5 for rules regarding required installments for corporations with a short taxable year.

(iv) Partial month. Except as otherwise provided, for purposes of determining the due date of any required installment a partial month shall be treated as a full month.

(g) Definitions. (1) The term tax as used in this section and §§1.6655-2 through 1.6655-7 means the excess of—

(i) The sum of—

(A) The tax imposed by section 11, section 1201(a), or subchapter L of chapter 1 of the Internal Revenue Code, whichever is applicable;

(B) The tax imposed by section 55; plus

(C) The tax imposed by section 887; over

(D) The credits against tax provided by part IV of subchapter A of chapter 1 of the Internal Revenue Code.

(ii) In the case of a foreign corporation subject to taxation under section 11, section 1201(a), or subchapter L of chapter 1 of the Internal Revenue Code, the tax imposed by section 881 shall be treated as a tax imposed by section 11.

(iii) In the case of a partnership that is treated, pursuant to regulations issued under section 1446(f)(2), as a corporation for purposes of this section, the tax imposed by section 1446 shall be treated as a tax imposed by section 11.

(2) For the purposes of paragraph (d)(2) of this section, the term return for the preceding taxable year means the Federal income tax return for such taxable year that is required by section 6012(a)(2). However, if an amended Federal income tax return has been filed before the due date for an installment, then the term return for the preceding taxable year means the Federal income tax return as amended. Paragraph (d)(2) of this section will apply without regard to whether the taxpayer’s Federal income tax return for the preceding taxable year is filed in a timely manner.

(3) If the tax rates for the current taxable year for which estimated tax is being determined differ from the rates applicable to the preceding taxable year, the tax determined for the preceding taxable year shall be recomputed using the rates applicable to the current taxable year.

(h) Special rules for consolidated returns. For special rules relating to the determination of the amount of the underpayment in the case of a corporation whose income is included in a consolidated return, see §1.1502-5(b).

(i) Overpayments applied to subsequent taxable year’s estimated tax—(1) In general. If a taxpayer elects under the provisions of sections 6402(b) and 6513(d) and the regulations to apply an overpayment in year one against the estimated tax liability for year two, the overpayment will be applied to the required installment payments for year two in the order due and to the extent necessary to satisfy such installments, similar to the manner in which an actual overpayment of one installment is carried forward to the next installment. No interest is accrued or paid on an overpayment if the election to apply the overpayment against estimated tax is made.

(2) Subsequent examinations. If a deficiency is determined in an examination of a return for a taxable year that originally reflected an overpayment that was applied against estimated tax for the succeeding taxable year, interest on the deficiency will not begin to accrue on an amount applied until that amount is used to satisfy a required estimated tax payment in such taxable year. Regardless of whether the taxpayer anticipated the application of such overpayment from the prior taxable year in calculating and paying its required estimated tax installment liabilities for the current taxable year, the subsequently determined underpayment and interest computation thereon will not change the taxpayer’s original election to apply the overpayment against the estimated tax liability of the succeeding taxable year. Any changes to the usage of the original overpayment from the prior taxable year are hypothetical only and solely for the purpose of computing deficiency interest. Overpayment interest will not be impacted. For further guidance, see Rev. Rul. 99-40, 1999-2 C.B. 441, (see §601.601(d)(2)(ii)(b) of this chapter).

(j) Examples. The method prescribed in paragraphs (d) through (g) of this section may be illustrated by the following examples:

Example 1. X, a calendar year corporation, estimates its tax liability for its taxable year ending December 31, 2006, will be $85,000. X is not a large corporation as defined in section 6655(g)(2) and §1.6655-4. X reported a liability of $74,900 on its return for the taxable year ended December 31, 2005, with no credits against tax. X paid four installments of estimated tax, each in the amount of $18,725 (25 percent of $74,900), on April 17, 2006, June 15, 2006, September 15, 2006, and December 15, 2006, respectively. X reported a tax liability of $88,900 on its return due March 15, 2007. X had a $5,000 credit against tax for tax year 2006 as provided by part IV of subchapter A of chapter 1 of the Internal Revenue Code. X did not underpay its estimated tax for tax year 2006 for any of the four installments, determined as follows:

(i) Tax as defined in paragraph (g) of this section for 2006 ($88,900-$5,000) $83,900
(ii) Tax as defined in paragraph (g) of this section for 2005 74,900
(iii) 100% of the lesser of this paragraph (j), Example 1 (i) or (ii) 74,900
(iv) Amount of estimated tax required to be paid on or before each installment date (25% of $74,900) 18,725
(v) Deduct amount paid on or before each installment date 18,725
(vi) Amount of underpayment for each installment date 0

Example 2. (i) Facts. Y, a calendar year corporation, estimates its tax liability for its taxable year ending December 31, 2006, will be $70,000. Y is not a large corporation as defined in section 6655(g)(2) and §1.6655-4. Y reported a Federal income tax liability of $90,000 for its taxable year ending December 31, 2005. Y paid no installment of estimated tax on or before April 17, 2006, June 15, 2006, or September 15, 2006, but made a payment of $63,000 on December 15, 2006. On March 15, 2007, Y filed its income tax return showing a tax of $70,000. Y had no credits against tax for tax year 2006. Of the $63,000 paid by Y on December 15, 2006, $17,500 is applied to each of the first three installments due on April 15, June 15, and September 15, 2006, and the remaining $10,500 is applied to the fourth installment. Y has an underpayment of estimated tax for each of the first three installments of $17,500 and for the fourth installment of $7,000. The addition to tax under section 6655(a) is computed as follows:

(A) Tax as defined in paragraph (g) of this section for 2006 $70,000
(B) Tax as defined in paragraph (g) of this section for 2005 90,000
(C) 100% of the lesser of this paragraph (j), Example 2 (i)(A) or (i)(B) 70,000
(D) Amount of estimated tax required to be paid on or before each installment date (25% of $70,000) 17,500
(E) Amount paid on or before the first, second, and third installment dates 0
(F) Amount paid on or before the fourth installment date 63,000
(G) Amount of underpayment for the first, second, and third installment dates 17,500
(H) Amount of underpayment for the fourth installment date 7,000

(ii) Addition to tax. Assuming that neither the annualized income installment method nor the adjusted seasonal installment method described in §§1.6655-2 and 1.6655-3 would result in a lower payment for any installment period, and the addition to tax is computed under section 6621(a)(2) at the rate of 8 percent per annum for the applicable periods of underpayment, the addition to tax is determined as follows:

(A) First installment (underpayment period 4-16-06 through 12-15-06), computed as 244/365 X $17,500 X 8% $936
(B) Second installment (underpayment period 6-16-06 through 12-15-06), computed as 183/365 X $17,500 X 8% 702
(C) Third installment (underpayment period 9-16-06 through 12-15-06), computed as 91/365 X $17,500 X 8% 349
(D) Fourth installment (underpayment period 12-16-06 through 3-15-07), computed as 90/365 X $7,000 X 8% 138
(E) Total of this paragraph (j), Example 2 (ii)(A) through (D) 2,125

(k) Effective date. This section applies to taxable years beginning after the date that is 30 days after the date the final regulations are published in the Federal Register.

§1.6655-2 Annualized income installment method.

(a) In general. In the case of any required installment, if the corporation establishes that the annualized income installment determined under this section, or the adjusted seasonal installment determined under §1.6655-3, is less than the amount determined under §1.6655-1—

(1) The amount of such required installment shall be the annualized income installment (or, if less, the adjusted seasonal installment); and

(2) Any reduction in a required installment resulting from the application of this section will be recaptured by increasing the amount of the next required installment determined under §1.6655-1 by the amount of such reduction (and, if the next required installment is similarly reduced, by increasing subsequent required installments to the extent that the reduction has not previously been recaptured).

(b) Determination of annualized income installmentIn general. In the case of any required installment, the annualized income installment is the excess (if any) of—

(1) The product of the applicable percentage and the tax for the taxable year computed by annualizing the taxable income and alternative minimum taxable income—

(i) For the first 3 months of the taxable year, in the case of the first required installment;

(ii) For the first 3 months of the taxable year, in the case of the second required installment;

(iii) For the first 6 months of the taxable year in the case of the third required installment; and

(iv) For the first 9 months of the taxable year, in the case of the fourth required installment; over

(2) The aggregate amount of any prior required installments for the taxable year.

(c) Special rules—(1) Applicable percentage. Except as otherwise provided in §1.6655-5(d) with respect to short taxable years—

In the case of the following required installments: The applicable percentage is:
1st 25
2nd 50
3rd 75
4th 100

(2) Partial month. Except as otherwise provided, for purposes of paragraph (b) of this section a partial month shall be treated as a month.

(d) Election of different annualization periods. (1) If the taxpayer timely files Form 8842, “Election To Use Different Annualization Periods for Corporate Estimated Tax,” in accordance with section 6655(e)(2)(C)(iii), and elects Option 1—

(i) Paragraph (b)(1)(i) of this section will be applied by using the language “2 months” instead of “3 months”;

(ii) Paragraph (b)(1)(ii) of this section will be applied by using the language “4 months” instead of “3 months”;

(iii) Paragraph (b)(1)(iii) of this section will be applied by using the language “7 months” instead of “6 months”; and

(iv) Paragraph (b)(1)(iv) of this section will be applied by using the language “10 months” instead of “9 months”.

(2) If the taxpayer timely files Form 8842, in accordance with section 6655(e)(2)(C)(iii), and elects Option 2—

(i) Paragraph (b)(1)(ii) of this section will be applied by using the language “5 months” instead of “3 months”;

(ii) Paragraph (b)(1)(iii) of this section will be applied by using the language “8 months” instead of “6 months”; and

(iii) Paragraph (b)(1)(iv) of this section will be applied by using the language “11 months” instead of “9 months”.

(e) 52-53 week taxable year. (1) Generally, in the case of a taxpayer whose taxable year constitutes 52 or 53 weeks in accordance with section 441(f), the rules prescribed by §1.441-2 shall be applicable in determining—

(i) Whether a taxable year is a taxable year of 12 months; and

(ii) When the 2-, 3- ,4-, 5-, 6-, 7-, 8-, 9-, 10-, or 11-month period (whichever is applicable) commences and ends for purposes of paragraphs (b)(1), (d)(1) and (d)(2) of this section.

(2) If a taxpayer employs four 13-week periods or thirteen 4-week accounting periods and the end of any accounting period employed by the taxpayer does not correspond to the end of the 2-, 3- ,4-, 5-, 6-, 7-, 8-, 9-, 10-, or 11-month period (whichever is applicable), then, provided the taxpayer has at least one full 4-week or 13-week accounting period, as appropriate, within the applicable period, annualized taxable income for the applicable period shall be—

(i) [(x/(y*13))*z], in the case of a taxpayer using four 13-week periods, if—

(A) x = Taxable income for the number of full 13-week periods in the applicable period;

(B) y = The number of full 13-week periods in the applicable period; and

(C) z = The number of weeks in the taxable year; or

(ii) [(x/(y*4))*z], in the case of a taxpayer using thirteen 4-week periods, if—

(A) x = Taxable income for the full 4-week periods in the applicable period;

(B) y = The number of full 4-week periods in the applicable period; and

(C) z = The number of weeks in the taxable year.

(3) If a taxpayer employs four 13-week periods and the taxpayer does not have at least one 13-week period within the applicable 2-, 3- ,4-, 5-, 6-, 7-, 8-, 9-, 10-, or 11-month period, the taxpayer shall be permitted to determine annualized taxable income for the applicable period based upon—

(i) The taxable income for the number of weeks in the applicable period; or

(ii) The taxable income for the full 13-week periods that end before the due date of the required installment.

(4) The following examples illustrate the rules of this paragraph (e):

Example 1. Taxpayer A, an accrual method taxpayer, uses a 52/53 week year-end ending on the last Friday in December and uses four thirteen-week periods. For its year beginning December 30, 2006, A uses the annualized income installment method under section 6655(e)(2)(A)(i) to calculate all of its required installments. For purposes of computing its first and second required installments, the first 3 months of A’s taxable year under paragraph (b)(1)(i) of this section will end on March 30th, the thirteenth Friday of A’s taxable year. For purposes of its third required installment, the first 6 months of A’s taxable year will end on June 29th, the twenty-sixth Friday of A’s taxable year. For purposes of its fourth required installment, the first 9 months of A’s taxable year will end on September 28th, the thirty-ninth Friday of A’s taxable year.

Example 2. Same facts as Example 1 except that A uses thirteen four-week periods and there are 52 weeks during A’s taxable year beginning December 30, 2006, and ending December 28, 2007. For purposes of computing A’s first and second required installments, A’s annualized taxable income for the first three months will be the taxable income for the first three four-week periods of A’s taxable year (December 30, 2006, through March 23, 2007) divided by 12 (number of full four-week periods in the first three months (3) multiplied by 4) and multiplied by 52 (the number of weeks in the taxable year). For purposes of computing A’s third required installment, A’s annualized taxable income for the first six months will be the taxable income for the first six four-week periods of A’s taxable year (December 30, 2006, through June 15, 2007) divided by 24 and multiplied by 52. For purposes of computing A’s fourth required installment, A’s annualized taxable income for the first nine months will be the taxable income for the first nine four-week periods of A’s taxable year (December 30, 2006, through September 7, 2007) divided by 36 and multiplied by 52.

(5) The application of the annualized income installment method is illustrated by the following example:

Example. (i) X, a calendar year corporation, had a taxable year of less than twelve months for tax year 2005 and no credits against tax for tax year 2006. X made an estimated tax payment of $15,000 on the installment dates of April 17, 2006, June 15, 2006, September 15, 2006, and December 15, 2006, respectively. Assume that, under paragraph (d)(1) of this section, X elected Option 1 by timely filing Form 8842, in accordance with section 6655(e)(2)(C)(iii), and determined that its taxable income for the first 2, 4, 7 and 10 months was $25,000, $64,000, $125,000, and $175,000 respectively. The income for each period is annualized as follows:

$25,000 X 12/2=$150,000
$64,000 X 12/4=$192,000
$125,000 X 12/7=$214,286
$175,000 X 12/10=$210,000

(ii)(A) To determine whether the installment payment made on April 17, 2006, equals or exceeds the amount that would have been required to have been paid if the estimated tax were equal to 100 percent of the tax computed on the annualized income for the 2-month period, the following computation is necessary:

(1) Annualized income for the 2 month period $150,000
(2) Tax on this paragraph (e)(5), Example (ii)(A)(1) 41,750
(3) 100% of this paragraph (e)(5), Example (ii)(A)(2) 41,750
(4) 25% of this paragraph (e)(5), Example (ii)(A)(3) 10,438

(B) Because the total amount of estimated tax that was timely paid on or before the first installment date ($15,000) exceeds the amount required to be paid on or before this date if the estimated tax were 100 percent of the tax determined by placing on an annualized basis the taxable income for the first 2-month period, the exception described in paragraphs (a) and (b) of this section applies, and no addition to tax will be imposed for the installment due on April 15, 2006.

(iii)(A) To determine whether the installment payments made on or before June 15, 2006, equal or exceed the amount that would have been required to have been paid if the estimated tax were equal to 100 percent of the tax computed on the annualized income for the 4-month period, the following computation is necessary:

(1) Annualized income for the 4 month period $192,000
(2) Tax on this paragraph (e)(5), Example (iii)(A)(1) 58,130
(3) 100% of this paragraph (e)(5), Example (iii)(A)(2) 58,130
(4) 50% of this paragraph (e)(5), Example (iii)(A)(3) less $10,438 (amount due with the first installment) 18,627

(B) Because the total amount of estimated tax actually paid on or before the second installment date ($19,562 ($15,000 second required installment payment plus $4,562 overpayment of first required installment)) exceeds the amount required to be paid on or before this date if the estimated tax were 100 percent of the tax determined by placing on an annualized basis the taxable income for the first 4-month period, the exception described in paragraphs (a) and (b) of this section applies, and no addition to tax will be imposed for the installment due on June 15, 2006.

(iv)(A) To determine whether the installment payments made on or before September 15, 2006, equal or exceed the amount that would have been required to have been paid if the estimated tax were equal to 100 percent of the tax computed on the annualized income for the 7-month period, the following computation is necessary:

(1) Annualized income for the 7 month period $214,286
(2) Tax on this paragraph (e)(5), Example (iv)(A)(1) 66,821
(3) 100% of this paragraph (e)(5), Example (iv)(A)(2) 66,821
(4) 75% of this paragraph (e)(5), Example (iv)(A)(3) less $29,065 (amount due with the first and second installment) 21,051

(B) Because the total amount of estimated tax actually paid on or before the third installment date ($15,935 ($15,000 third required installment payment plus $935 overpayment of second required installment)) does not equal or exceed the amount required to be paid on or before this date if the estimated tax were 100 percent of the tax determined by placing on an annualized basis the taxable income for the first 7-month period, the exception described in paragraphs (a) and (b) of this section does not apply, and an addition to tax will be imposed with respect to the underpayment of the September 15, 2006, installment unless another exception applies to this installment payment.

(v)(A) To determine whether the installment payments made on or before December 15, 2006, equal or exceed the amount that would have been required to have been paid if the estimated tax were equal to 100 percent of the tax computed on the annualized income for the 10-month period, the following computation is necessary:

(1) Annualized income for the 10 month period $210,000
(2) Tax on this paragraph (e)(5), Example (v)(A)(1) 65,150
(3) 100% of this paragraph (e)(5), Example (v)(A)(2) 65,150
(4) 100% of this paragraph (e)(5), Example (v)(A)(3) less $50,116 (amount due with the first, second, and third installment) 15,034

(B) Because the total amount of estimated tax payments made on or before the fourth installment date that is available to be applied to the estimated tax due for the fourth installment ($9,884 ($15,000 fourth required installment payment less $5,116 underpayment for the third installment of estimated tax ($21,051 third installment of estimated tax due less $15,935 payments available to be applied to the third installment of estimated tax))) does not equal or exceed the amount required to be paid on or before this date if the estimated tax were 100 percent of the tax determined by placing on an annualized basis the taxable income for the first 10-month period, the exception described in paragraphs (a) and (b) of this section does not apply, and an addition to tax will be imposed with respect to the underpayment of the December 15, 2006, installment unless another exception applies to this installment payment.

(vi) Assuming that no other exceptions apply and the addition to tax is computed under section 6621(a)(2) at the rate of 8 percent per annum for the applicable periods of underpayment, the amount of the addition to tax is as follows:

(A) First installment (no underpayment)  
(B) Second installment (no underpayment)  
(C) Third installment (underpayment period 9-16-06 through 12-15-06), computed as 91/365 X $5,116 X 8% 102
(D) Fourth installment (underpayment period 12-16-06 through 3-15-07), computed as 90/365 X $5,150 X 8% 102
(E) Total of this paragraph (e)(5), Example (vi)(A) through (D) 204

(f) Determination of taxable income for an annualization period—(1) In general. In determining the applicability of the exception described in paragraphs (a) and (b) of this section (relating to the annualization of income) and the exception described in §1.6655-3 (relating to annualization of income for corporations with seasonal income), and for purposes of computing a taxpayer’s taxable income (and applicable tax), an item must be taken into account in computing a taxpayer’s taxable income for the taxable year for which the estimated tax is being determined, and must be properly taken into account in determining a taxpayer’s taxable income (and applicable tax) for the applicable annualization period by the last day of the such period. Generally, except as provided in paragraph (f)(2) of this section, for an item to be taken into account during an annualization period, the following must occur on or before the last day of the applicable annualization period (determined based on the accounting period employed by the taxpayer):

(i) With respect to an item of gross income, such income is includible in computing taxable income in accordance with section 451 or the appropriate provision of the Internal Revenue Code (for example, section 453 for installment sales or section 460 for long-term contracts).

(ii) With respect to an item of loss, the loss must be permitted to be taken into account under the appropriate provision of the Internal Revenue Code.

(iii) With respect to an item of deduction, for taxpayers using the cash receipts and disbursements method of accounting, the deduction must be paid under §1.461-1(a)(1) and otherwise deductible in computing taxable income for the annualization period or, for taxpayers using an accrual method of accounting, the deduction must be incurred under §1.461-1(a)(2) and otherwise deductible in computing taxable income for the annualization period. In the case of an accrual method taxpayer, the provisions of section 170(a)(2) and §1.170A-11(b) (charitable contributions by accrual method corporations), §1.461-4(d)(6)(ii) (provision of services or property to a taxpayer), §1.461-5 (recurring item exception), and any other provision that has a similar effect can not be used in determining whether the item of deduction has been incurred under §1.461-1(a)(2) and is otherwise deductible for purposes of computing taxable income for an annualization period. For purposes of section 404 and the regulations, regardless of the overall method of accounting employed by the taxpayer, the applicable 2-, 3-,
