Refund claimed with original Maryland return

If you expect a refund from your original return, do not file an amended return until you receive your refund. Do not return the refund to us.

If your amended return shows a smaller refund, submit your payment for the difference with the amended return. If your amended return shows a larger refund, you will be issued an additional refund check.

Changes to federal return

If the IRS makes any changes to your federal return, you must send a notification to the Maryland Revenue Administration Division within 90 days of the final determination of the changes by IRS.

If you file an amended federal return that changes your Maryland return, you must file an amended Maryland return.

For more information about amended returns, see Instruction 28 in the Maryland tax booklet.
