    If You Owe Income Taxes and Need a Tax Extension

      • Taxpayers do not have to submit PA Form REV-276 or federal Form 4868.

    Federal Approval has yet to be received:

    • Complete Form REV-276 by April 15th and mail form to the address listed on the form.

    Do I Need to Pay My State Taxes When I File a Tax Extension for Pennsylvania?

    Yes, you must pay your estimated taxes by April 15th, even if you file for an extension. 

    An extension to file is not an extension to pay. 

    You should send a payment for the amount of tax you expect to owe to avoid penalties and interest.

    What Are the Penalties for Filing My Taxes Late in Pennsylvania?

    If you do not pay your taxes due by April 15th, you will be subject to a 5% underpayment penalty plus interest on the amount not paid by the original due date.

    If you do not file your taxes by the April 15th deadline (and you do not request an extension), you'll incur a 5% penalty plus interest.

    Late Filing Penalty:

    • Calculate 5% of the unpaid tax for each month or a fraction of a month the return is late.
    • The maximum penalty is 25% of the unpaid tax.
    • Example: If you owe $1,000 and file 2 months late, the penalty would be $100 (5% x 2 months x $1,000).


    • Interest accrues on unpaid taxes from the original due date until the tax is paid in full.
    • The interest rate can vary, so check the current rate with the PA Department of Revenue.
    • Refer to the Penalty & Interest Calculator for Pennsylvania to help you calculate interest owed based on your criteria. 

    How Do I Know Whether I Should File a Tax Extension for Pennsylvania?

    You should consider filing a tax extension if you are unable to complete your Pennsylvania tax return by April 15th. 

    This can help you avoid late-filing penalties. 

    However, remember that you still need to pay any estimated taxes owed by the original deadline.

    Is There Anything Else I Need to Know About Filing a Tax Extension for Pennsylvania?

    • If you applied for a federal extension, attach a copy of Form 4868 to your Pennsylvania return.
    • If filing an extension, make sure to pay any taxes owed by the April 15th deadline.
