Maryland State Tax Extension
When filing your Maryland state income tax return, you may need to request an extension if you cannot complete and submit your return by the original deadline. The extension allows you additional time to file your return, but it does not extend the time to pay any taxes owed. You must still pay any estimated tax liability by the original due date to avoid penalties and interest.
How to Request an Extension
- Use the Extension Worksheet provided in the Maryland Resident Tax Booklet (Form 502 instructions) to calculate your expected tax liability and allowable credits.
- Complete Line 1 (Income tax) and Line 4 (Estimated allowable credits) on the worksheet.
- Calculate Line 5 (Total payments and credits) by adding withholding, estimated tax payments, and other credits.
- Submit your extension request by filing Form 502 with the extension worksheet attached.
Important Deadlines
The original filing deadline for Maryland individual income tax returns is typically April 15. If you file for an extension, you will have until October 15 to file your return. However, any tax due must be paid by April 15 to avoid interest and penalties.
Payment Instructions
Even if you file for an extension, you must pay any estimated tax liability by the original due date. Payments can be made electronically or by mail. Be sure to attach all required forms, including W-2s, 1099s, and K-1s, to your return if Maryland tax was withheld.
Software Assistance
OLT (Online Taxes) software can guide you through adding forms such as Form 502 and Form MD PVW during your Maryland state tax filing. Navigate to the "State" section in the software, select "Start or Revisit Maryland State," and follow on-screen prompts to enter your personal, income, and deduction information.
