Changes To Note

  • For tax years ending on or after December 31, 2001, certain corporations with average annual gross receipts of more than $1 million but less than or equal to $10 million may be able to adopt or change to the cash method of accounting for eligible trades or businesses. This rule does not apply to corporations prohibited from using the cash method under section 448. For more details, including change in accounting method requirements, see Notice 2001-76, 2001-52 I.R.B. 614.
  • The corporation may need to mail its return to a different service center this year because the IRS has changed the filing location for several areas. If an envelope was received with the tax package, please use it. Otherwise, see Where To File on page 3.
  • A corporation may request that the IRS deposit its income tax refund directly into its checking or savings account at any U.S. bank or other financial institution that accepts direct deposits. For details, see the instructions for line 36 on page 14, and new Form 8050, Direct Deposit of Corporate Tax Refund.
  • If the corporation wants to allow the IRS to discuss its 2001 tax return with the paid preparer who signed it, check the Yes box in the area where the officer of the corporation signed the return. See page 3 for details.

Photographs of Missing Children

The Internal Revenue Service is a proud partner with the National Center for Missing and Exploited Children. Photographs of missing children selected by the Center may appear in instructions on pages that would otherwise be blank. You can help bring these children home by looking at the photographs and calling 1-800-THE-LOST (1-800-843-5678) if you recognize a child.

Unresolved Tax Issues

If the corporation has attempted to deal with an IRS problem unsuccessfully, it should contact the Taxpayer Advocate. The Taxpayer Advocate independently represents the corporation's interests and concerns within the IRS by protecting its rights and resolving problems that have not been fixed through normal channels.

While Taxpayer Advocates cannot change the tax law or make a technical tax decision, they can clear up problems that resulted from previous contacts and ensure that the corporation's case is given a complete and impartial review.

The corporation's assigned personal advocate will listen to its point of view and will work with the corporation to address its concerns. The corporation can expect the advocate to provide:

  • A "fresh look" at a new or on-going problem.
  • Timely acknowledgment.
  • The name and phone number of the individual assigned to its case.
  • Updates on progress.
  • Timeframes for action.
  • Speedy resolution.
  • Courteous service.

When contacting the Taxpayer Advocate, the corporation should provide the following information:

  • The corporation's name, address, and employer identification number (EIN).
  • The name and telephone number of an authorized contact person and the hours he or she can be reached.
  • The type of tax return and year(s) involved.
  • A detailed description of the problem.
  • Previous attempts to solve the problem and the office that had been contacted.
  • A description of the hardship the corporation is facing (if applicable).

The corporation may contact a Taxpayer Advocate by calling 1-877-777-4778 (toll free). Persons who have access to TTY/TDD equipment may call 1-800-829-4059 and ask for Taxpayer Advocate assistance. If the corporation prefers, it may call, write, or fax the Taxpayer Advocate office in its area. See Pub. 1546, The Taxpayer Advocate Service of the IRS, for a list of addresses and fax numbers.

In addition, anyone who prepares Form 1120 or Form 1120-A but does not charge the corporation should not complete that section.

Paid Preparer Authorization

If the corporation wants to allow the IRS to discuss its 2001 tax return with the paid preparer who signed it, check the Yes box in the signature area of the return. This authorization applies only to the individual whose signature appears in the Paid Preparer's Use Only section of the corporation's return. It does not apply to the firm, if any, shown in that section.

If the Yes box is checked, the corporation is authorizing the IRS to call the paid preparer to answer any questions that may arise during the processing of its return. The corporation is also authorizing the paid preparer to:

  • Give the IRS any information that is missing from the return,
  • Call the IRS for information about the processing of the return or the status of any related refund or payment(s), and
  • Respond to certain IRS notices that the corporation has shared with the preparer about math errors, offsets, and return preparation. The notices will not be sent to the preparer.

The corporation is not authorizing the paid preparer to receive any refund check, bind the corporation to anything (including any additional tax liability), or otherwise represent the corporation before the IRS. If the corporation wants to expand the paid preparer's authorization, see Pub. 947, Practice Before the IRS and Power of Attorney.

The authorization cannot be revoked. However, the authorization will automatically end no later than the due date (excluding extensions) for filing the corporation's 2002 tax return.
