This tax calendar has the due dates for 2001 that most taxpayers will need. Employers and persons who pay excise taxes should also use the Employer's Tax Calendar and the Excise Tax Calendar.

Fiscal-year taxpayers. If you file your income tax return for a fiscal year rather than the calendar year, you must change some of the dates in this calendar. These changes are described under Fiscal-Year Taxpayers at the end of this calendar.

First Quarter

The first quarter of a calendar year is made up of January, February, and March.

January 10

Employees who work for tips. If you received $20 or more in tips during December, report them to your employer. You can use Form 4070, Employee's Report of Tips to Employer.

January 16

Individuals. Make a payment of your estimated tax for 2000 if you did not pay your income tax for the year through withholding (or did not pay in enough tax that way). Use Form 1040-ES. This is the final installment date for 2000 estimated tax. However, you do not have to make this payment if you file your 2000 return (Form 1040) and pay any tax due by January 31, 2001.

Farmers and fishermen. Pay your estimated tax for 2000 using Form 1040-ES. You have until April 16 to file your 2000 income tax return (Form 1040). If you do not pay your estimated tax by January 16, you must file your 2000 return and pay any tax due by March 1, 2001, to avoid an estimated tax penalty.

January 31

Individuals. File your income tax return (Form 1040) for 2000 if you did not pay your last installment of estimated tax by January 16. Filing your return and paying any tax due by January 31 prevents any penalty for late payment of the last installment.

All businesses. Give annual information statements to recipients of certain payments you made during 2000. (You can use the appropriate version of Form 1099 or other information return.) Payments that are covered include the following.

• Compensation for workers who are not considered employees (including fishing boat proceeds to crew members).
• Dividends and other corporate distributions.
• Interest.
• Amounts paid in real estate transactions.
• Rent.
• Royalties.
• Amounts paid in broker and barter exchange transactions.
• Payments to attorneys.
• Payments of Indian gaming profits to tribal members.
• Profit-sharing distributions.
• Retirement plan distributions.
• Original issue discount.
• Prizes and awards.
• Medical and health care payments.
• Debt cancellation (treated as payment to debtor).
• Cash payments over $10,000. (See the instructions for Form 8300, Report of Cash Payments Over $10,000 Received in a Trade or Business.)

See the 2000 Instructions for Forms 1099, 1098, 5498, and W-2G for information on what payments are covered, how much the payment must be before a statement is required, which form to use, and extension of time to provide statements.

February 15

Individuals. If you claimed exemption from income tax withholding last year on the Form W-4 you gave your employer, you must file a new Form W-4 by this date to continue your exemption for another year.

February 28

All businesses. File information returns (Form 1099) for certain payments you made during 2000. These payments are described under January 31. There are different forms for different types of payments. Use a separate Form 1096 to summarize and transmit the forms for each type of payment. See the 2000 Instructions for Forms 1099, 1098, 5498, and W-2G for information on what payments are covered, how much the payment must be before a return is required, what form to use, and extensions of time to file.

If you file Forms 1098, 1099, or W-2G electronically (not by magnetic media), your due date for filing them with the IRS will be extended to April 2. The due date for giving the recipient these forms will still be January 31.

March 1

Farmers and fishermen. File your 2000 income tax return (Form 1040) to avoid an underpayment penalty if you owe estimated tax. However, you have until April 16 to file if you paid your 2000 estimated tax by January 16, 2001.

March 12

Employees who work for tips. If you received $20 or more in tips during February, report them to your employer. You can use Form 4070.

S corporation election. File Form 2553, Election by a Small Business Corporation, to choose to be treated as an S corporation beginning with calendar year 2001. If Form 2553 is filed late, S treatment will begin with calendar year 2002.

Electing large partnerships. Provide each partner with a copy of Schedule K-1 (Form 1065-B), Partner's Share of Income (Loss) From an Electing Large Partnership.
