This publication contains the following.

Primarily, employers need to use this publication. However, the general tax calendar has important due dates for all businesses and individuals. Anyone who must pay excise taxes may need the excise tax calendar.

The following are advantages of using a calendar.

To decide which calendar(s) to use, first look at the general tax calendar and highlight the dates that apply to you. Then, if you are an employer, use the Employer's Tax Calendar. If you must pay excise taxes, use the Excise Tax Calendar. Depending on your situation, you may need to use more than one calendar.

The calendars do not cover the employment or excise tax deposit rules. You can find the deposit rules for employment taxes in Publication 15, Circular E, Employer's Tax Guide. The deposit rules for excise taxes are in Publication 510, Excise Taxes for 2004, and in the instructions for Form 720, Quarterly Federal Excise Tax Return. In addition, the calendars do not cover filing forms and other requirements for the following.

Table 1 lists other publications you may need to order. Each calendar lists the forms you may need.

See How To Get Tax Help near the end of this publication for information about getting publications and forms.

Some taxes can be paid with the return on which they are reported. However, in many cases, you have to deposit the tax before the due date for filing the return. Tax deposits are figured for periods of time that are shorter than the time period covered by the return. See Publication 15 for the employment tax deposit rules. For the excise tax deposit rules, see Publication 510 or the instructions for Form 720.

Deposits must be made at an authorized financial institution. A deposit received after the due date will be considered timely if you can establish that it was mailed in the United States at least 2 days before the due date. However, deposits of $20,000 or more by a person required to deposit the tax more than once a month must be received by the due date to be timely.

Each deposit must be accompanied by a federal tax deposit (FTD) coupon, Form 8109, unless you are using the Electronic Federal Tax Payment System (EFTPS). The coupons have spaces for indicating the type of tax you are depositing. You must use a separate coupon for each type of tax. For example, if you are depositing both excise taxes and federal unemployment taxes, you must use two coupons. You can get the coupons you need by calling 1–800–829–4933. See How To Get Tax Help near the end of this publication for more information about ordering forms.

You may have to deposit taxes using EFTPS. You must use EFTPS to make deposits of all depository tax liabilities (including social security, Medicare, withheld income, excise, and corporate income taxes) you incur in 2004 if you deposited more than $200,000 in federal depository taxes in 2002 or you had to make electronic deposits in 2003. If you first meet the $200,000 threshold in 2003, you must begin depositing using EFTPS in 2005. Once you meet the $200,000 threshold, you must continue to make deposits using EFTPS in later years.

If you must use EFTPS but fail to do so, you may be subject to a 10% penalty.

If you are not required to use EFTPS because you did not meet the $200,000 threshold during 1998, or during any subsequent year, then you may voluntarily make your deposits using EFTPS. If you are using EFTPS voluntarily, you will not be subject to the 10% penalty if you make a deposit using a paper coupon.

For information about EFTPS, visit www.eftps.gov or see Publication 966, Electronic Choices for Paying ALL Your Federal Taxes.

Generally, if a due date for performing any act for tax purposes falls on a Saturday, Sunday, or legal holiday, it is delayed until the next day that is not a Saturday, Sunday, or legal holiday. These calendars make this adjustment for Saturdays, Sundays, and most legal holidays. But you must make any adjustments for statewide legal holidays. (An exception to this rule for certain excise taxes is noted later under the Excise Tax Calendar.)

A statewide legal holiday delays a due date only if the IRS office where you are required to file is located in that state.

Federal legal holidays for 2004 are listed below.

Whenever possible, you should take action before the listed due date. If you are late, you may have to pay a penalty as well as interest on any overdue taxes.

Be sure to follow all the tax laws that apply to you. In addition to civil penalties, criminal penalties may be imposed for intentionally not paying taxes, for intentionally filing a false return, or for not filing a required return.

You can use certain private delivery services designated by the IRS to meet the timely mailing as timely filing/paying rule for tax returns and payments. The most recent list of designated private delivery services was published by the IRS in September 2002. The list includes only the following.

The private delivery service can tell you how to get written proof of the mailing date.

The U.S. Postal Service advises that private delivery services cannot deliver items to P.O. boxes. You must use the U.S. Postal Service to mail any item to an IRS P.O. box address.
