  Most of the due dates discussed in this publication are also included in the IRS Tax Calendar available at The online IRS Tax calendar is also available in Spanish.

Who should use this publication?   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 .

What are the advantages of using a tax calendar?   The following are advantages of using a calendar.
  • You do not have to figure the due dates yourself.

Background Information for Using the Tax Calendars

The following brief explanations may be helpful to you in using the tax calendars.

IRS e-services make taxes easier.   Now more than ever before, businesses can enjoy the benefits of filing and paying their federal taxes electronically. Whether you rely on a tax professional or handle your own taxes, the IRS offers you convenient programs to make taxes easier.

  • You can e-file your Form 1040; certain business tax returns such as Forms 1120, 1120S, and 1065; certain employment tax returns such as Forms 940 and 941; certain excise tax returns such as Forms 720, 2290, and 8849; and Form 1099 and other information returns. Visit for more information.

  • You can pay taxes online or by phone using the Electronic Federal Tax Payments System (EFTPS). For detailed information about using this free service, see Electronic deposit requirement below.

  Use these electronic options to make filing and paying taxes easier. For more information on electronic payments, visit the IRS website at

Tax deposits.   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 (Circular E) for the employment tax deposit rules. For the excise tax deposit rules, see Publication 510 or the Instructions for Form 720.


Electronic deposit requirement.   You must use electronic funds transfer to make all federal tax deposits (such as deposits of employment tax, excise tax, and corporate income tax). Generally, electronic fund transfers are made using the Electronic Federal Tax Payment System (EFTPS). EFTPS is a free service provided by the Department of Treasury. If you do not want to use EFTPS, you can arrange for your tax professional, financial institution, payroll service, or other trusted third party to make electronic deposits on your behalf.

  To get more information or to enroll in EFTPS, call 1-800-555-4477 (business), 1-800-316-6541 (individual), or 1-800-733-4829 (TTY/TDD). You can also visit the EFTPS website at Additional information about EFTPS is also available in Publication 966, Electronic Federal Tax Payment System: A Guide to Getting Started.

If you fail to timely, properly, and in full make your federal tax deposit, you may be subject to a failure-to-deposit penalty. For an EFTPS deposit to be on time, you must submit the deposit by 8 p.m. Eastern time the day before the date the deposit is due.

Saturday, Sunday, or legal holiday.   Generally, if a due date for performing any act for tax purposes falls on a Saturday, Sunday, or legal holiday, the act is considered to be performed timely if it is performed no later than the next day that is not a Saturday, Sunday, or legal holiday. The term legal holiday means any legal holiday in the District of Columbia. The calendars provided in this publication make the adjustment for Saturdays, Sundays, and legal holidays. But you must make any adjustments for statewide legal holidays, as discussed next.

An exception to this rule for certain excise taxes is noted later under the Excise Tax Calendar.

Legal holidays.   Legal holidays for 2015 are listed below.
  • January 1— New Year's Day

  • January 19— Birthday of Martin Luther King, Jr. / Inauguration Day

  • February 16— Washington's Birthday

  • April 16— District of Columbia Emancipation Day

  • May 25— Memorial Day

  • July 3— Independence Day (observed)

  • September 7— Labor Day

  • October 12— Columbus Day

  • November 11— Veterans Day

  • November 26— Thanksgiving Day

  • December 25— Christmas Day

Statewide legal holidays.   A statewide legal holiday delays a due date for filing a return only if the IRS office where you are required to file is located in that state. A statewide legal holiday does not delay a due date for making a federal tax deposit.

Extended due date for Forms 1098, 1099, and W-2 if filed electronically.   If you file Forms 1098, 1099, or W-2 electronically, your due date for filing them with the IRS or the Social Security Administration (SSA) will be extended to March 31.

  For 2015, the due date for giving the recipient these forms is February 2.

  For information about filing Forms 1098, 1099, or W-2G electronically, see Publication 1220, Specifications for Electronic Filing of Forms 1097, 1098, 1099, 3921, 3922, 5498, 8935, and W-2G. For information about filing Form W-2 electronically with the SSA, visit or call 1-800-772-6270 or 1-800-325-0778 (TTY/TDD).

Penalties.   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.

Use of private delivery services.   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. These private delivery services include only the following.
  • DHL Express (DHL): DHL Same Day Service.

  • Federal Express (FedEx): FedEx Priority Overnight, FedEx Standard Overnight, FedEx 2 Day, FedEx International Priority, and FedEx International First.

  • United Parcel Service (UPS): UPS Next Day Air, UPS Next Day Air Saver, UPS 2nd Day Air, UPS 2nd Day Air A.M., UPS Worldwide Express Plus, and UPS Worldwide Express.

  For the IRS mailing address to use if you are using a private delivery service, go to and enter “private delivery service” in the search box.

  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.
