Filing an Extension in Maryland

The Maryland Revenue Administration Division will allow you an automatic six-month extension of time in which to file your state return (Maryland 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 Maryland 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, 2023.

If no tax is due and you did not request a federal extension, you can request a six-month Maryland extension online or by calling 410-260-7829 from Central Maryland or toll-free 1-800-260-3664 from elsewhere.

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, 2023. 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.

Penalty and Interest Charges on Tax Owed

  • Interest will be assessed at a rate of 13% per year (1.08% per month) from April 15, 2023 until the date of payment. Interest accrues regardless of an approved extension request.
  • An additional Late Payment Penalty can be assessed for up to 25% of the amount of tax you owe.
  • There is a substantial Late Filing Penalty for not filing or late filing of your tax return.

If You Do Not Owe

If you do not owe any Maryland taxes on your return, do not file Maryland Form 502E. Maryland Revenue Administration Division only accepts extension requests on Form 502E if there is a balance due on the return.
