How do I file a Maryland Extension?
If no tax is due and you requested a federal extension, you don't need to file any forms or take any action to obtain an automatic six month extension.
We can help you file a federal extension and pay any Maryland tax due. To get started, visit Menu Path: Account > File an Extension.
If you do not expect to owe tax and have not requested a federal extension, you may request a Maryland extension by telefile by calling 410-260-7829 from central Maryland or 1-800-260-3664 from elsewhere.
