30. How To Figure Your Tax

Table of Contents

Introduction

After you have figured your income and deductions as explained in Parts One through Five, your next step is to figure your tax. This chapter discusses:

The general steps you take to figure your tax,
An additional tax you may have to pay called the alternative minimum tax, and
The conditions you must meet if you want the IRS to figure your tax.

Figuring Your Tax

Your income tax is based on your taxable income. After you figure your income tax and any alternative minimum tax, subtract your tax credits and add any other taxes you may owe. The result is your total tax. Compare your total tax with your total payments to determine whether you are entitled to a refund or owe additional tax.

This section provides a general outline of how to figure your tax. You can find step-by-step directions in the instructions for Forms 1040EZ, 1040A, and 1040. If you are unsure of which tax form you should file, see Which Form Should I Use? in chapter 1.

Tax. Most taxpayers use either the Tax Table or the Tax Computation Worksheet to figure their income tax. However, there are special methods if your income includes any of the following items.

A net capital gain. (See chapter 16.)
Qualified dividends taxed at the same rates as a net capital gain. (See chapter 16.)
Lump-sum distributions. (See chapter 10.)
Farming or fishing income. (See Schedule J (Form 1040), Income Averaging for Farmers and Fishermen.)
Investment income over $1,600 for children under age 14. (See chapter 31.)

Credits. After you figure your income tax and any alternative minimum tax (discussed later), determine your tax credits. This chapter does not explain whether you are eligible for these credits. You can find that information in chapters 32 through 37 and your form instructions. See the following table for credits you may be able to subtract from your income tax.

Some credits (such as the earned income credit) are not listed above because they are treated as payments. See Payments, later.

There are other credits that are not discussed in this publication. These include the following items.

Credit for fuel from a nonconventional source, which is for the person who sold the fuel or who owned royalty interests and received income from the sale of fuel produced from a nonconventional source. See Form 8907.

Other taxes. After you subtract your tax credits, determine whether there are any other taxes you must pay. This chapter does not explain these other taxes. You can find that information in other chapters of this publication and your form instructions. See the following table for other taxes you may need to add to your income tax.

Uncollected social security and Medicare tax on group-term life insurance.

This chapter does not explain these payments and credits. You can find that information in other chapters of this publication and your form instructions.

Refund or balance due. To determine whether you are entitled to a refund or owe additional tax, compare your total payments with your total tax. If you are entitled to a refund, see your form instructions for information on having it directly deposited into your checking or savings account instead of receiving a paper check.

Alternative Minimum Tax

This section briefly discusses an additional tax you may have to pay.

The tax law gives special treatment to some kinds of income and allows special deductions and credits for some kinds of expenses. Taxpayers who benefit from the law in these ways may have to pay at least a minimum amount of tax through an additional tax. This additional tax is called the alternative minimum tax (AMT).

You may have to pay the alternative minimum tax if your taxable income for regular tax purposes, combined with certain adjustments and tax preference items, is more than:

$58,000 if your filing status is married filing a joint return (or qualifying widow(er) with dependent child),
$40,250 if your filing status is single or head of household, or
$29,000 if your filing status is married filing a separate return.

Adjustments and tax preference items. The more common adjustments and tax preference items include:

Addition of personal exemptions,
Addition of the standard deduction (if claimed),
Addition of itemized deductions claimed for state and local taxes, certain interest, most miscellaneous deductions, and part of medical expenses,
Subtraction of any refund of state and local taxes included in gross income,
Changes to accelerated depreciation of certain property,
Difference between gain or loss on the sale of property reported for regular tax purposes and AMT purposes,
Addition of certain income from incentive stock options,
Change in certain passive activity loss deductions,
Addition of certain depletion that is more than the adjusted basis of the property,
Addition of part of the deduction for certain intangible drilling costs, and
Addition of tax-exempt interest on certain private activity bonds.

More information. For more information about the alternative minimum tax, see the instructions for Form 1040, line 45, and Form 6251, Alternative Minimum Tax—Individuals.

Tax Figured by IRS

If you file by April 17, 2006, you can have the IRS figure your tax for you on Form 1040EZ, Form 1040A, or Form 1040.

If the IRS figures your tax and you paid too much, you will receive a refund. If you did not pay enough, you will receive a bill for the balance. To avoid interest or the penalty for late payment, you must pay the bill within 30 days of the date of the bill or by the due date for your return, whichever is later.

You want your refund directly deposited into your account.
