Pittsburgh - Federal Tax Extension Information
Provides forms to request an extension of time to file a U.S. Tax Return. There are three ways to request an automatic extension of time to file a U.S. individual income tax return: (1) electronically file Form 4868 (PDF), Application For Automatic Extension of Time To File U.S. Individual Tax Return; (2) you can pay all or part of your estimate of income tax due using a credit or debit card or by using the Electronic Federal Tax Payment System (EFTPS); or (3) you can file a paper Form 4868 by mail.

If you file your Form 4868 electronically you will receive an acknowledgement or confirmation number for your records and you do not need to mail in Form 4868. If you need to pay additional taxes when filing Form 4868 electronically, you may do so through the outside service provider or through e-file. You can refer to your tax software or tax professional for ways to file electronically using e-file services. Several companies offer free filing of Form 4868 through the Free File program that you can access
