General Instructions

The Maryland Revenue Administration Division will allow you an automatic six-month extension of time in which to file your state return (Form 502, 503, 505, or 513) if you filed a federal extension and expect to owe zero tax to Maryland.

You are not required to file Form 502E in order to obtain this automatic extension. However, you should use Form 502E to pay any tax due in order to avoid any late payment penalty and interest on tax not paid by April 15, 2014.

An extension to file your return is not an extension of time to pay your taxes.

If You Owe

To avoid penalties and interest, you must pay your current year tax liability in full on or before April 15, 2014. Filing for an extension does not extend the time to pay your taxes. Any tax not paid by the original due date of the Maryland return will be assessed interest from the due date to the payment date. There are additional penalties for late payment of taxes or for filing your tax return late.

If you want the Revenue Administration Division to figure your tax, simply provide them with the necessary information and a written request for them to complete the return. Do not file Form 502E. Also, if you have completed your return but are unable to pay your tax in full, do not file Form 502E. File your return.

Pay Online

Pay your taxes online at Under Online Services, click on “request an extension.” Direct debit from your savings or checking account, and credit card are accepted forms of payment.
