How to find your amended return refund in Maryland
Maryland processes amended returns through the Comptroller's office, and tracking your refund depends on whether you filed by mail or electronically. If you filed Form 502X (the Maryland amended return form) by mail, the Comptroller's office typically takes 8 to 12 weeks to process it after they receive it. If you filed electronically through a tax software or tax professional, processing usually takes 4 to 6 weeks. The fastest way to check status is through the Maryland Comptroller's website using your Social Security number and tax year.
The Comptroller does not send status updates by email or phone, so you will need to check the website yourself. If your refund was approved, it will be issued by check or direct deposit, depending on what you indicated on your amended return. Checks are mailed from Annapolis and typically arrive within 7 to 10 business days after the Comptroller issues them. Direct deposits post within 3 to 5 business days of issuance.

Checking your status on the Maryland Comptroller website
Go to marylandtaxes.gov and look for the "Check Your Refund Status" tool. You will need your Social Security number, the tax year of the amended return, and your date of birth. Enter this information and the system will show you whether your amended return is still being processed, has been approved, or requires additional information.
The status page will tell you the date your refund was issued if it has been approved. Write down this date — it marks the beginning of the delivery window. If the page shows "pending" or "processing," your return is still in the queue and you should check again in one week. If it shows "rejected" or "more information needed," a notice will arrive by mail within 5 to 7 business days explaining what went wrong or what documents the Comptroller needs from you.
What the different status messages mean
Processing: Your amended return has been received and is waiting to be reviewed. This is normal and expected. Do not contact the Comptroller during this phase unless more than 12 weeks have passed since you mailed the return or more than 6 weeks since you filed electronically.
Approved: Your amended return has been accepted and your refund has been issued. The status page will show the issue date. If you chose direct deposit, the money should arrive within 3 to 5 business days. If you chose a check, allow 7 to 10 business days for mail delivery from Annapolis.
Rejected or More Information Needed: The Comptroller found a problem with your amended return or needs you to send additional documents. A formal notice will arrive by mail explaining what is missing or incorrect. Follow the instructions in that notice exactly. Do not send documents to the Comptroller without first receiving this notice, as they may be lost.
Delivery timeline after your refund is issued
| Refund Method | Time to Arrive After Issue Date | What to Expect |
|---|---|---|
| Direct Deposit | 3 to 5 business days | Money appears in your bank account; no physical mail |
| Check by Mail | 7 to 10 business days | Check arrives at the address on your amended return; may take longer in rural areas |
Business days do not include weekends or state holidays. If your refund was issued on a Friday, the 3 to 5 day window for direct deposit begins on Monday. If you do not see your direct deposit after 5 business days, contact your bank to confirm they received it. If you do not receive your check after 10 business days, contact the Comptroller's office.
What to do if your refund is late
If your direct deposit has not arrived after 5 business days from the issue date, call your bank first. Ask them to search for any pending deposits from the Maryland Comptroller. Sometimes deposits are delayed on the bank's end, not the state's. If your bank has no record of the deposit, note the issue date from the Comptroller's website and contact the Comptroller's Refund Unit at 410-260-7801.
If your check has not arrived after 10 business days, wait one more week before contacting the Comptroller. Mail from Annapolis can take longer during high-volume periods or if you live outside the Baltimore-Washington area. If 14 business days have passed since the issue date, call the Refund Unit at 410-260-7801 with your Social Security number, the tax year, and the issue date. They can issue a replacement check or direct deposit if the original was lost.
When you call, have your amended return and the status page printout in front of you. The Comptroller's office receives many calls during tax season, so call early in the morning or on Tuesday through Thursday for shorter wait times. Do not call on Mondays or Fridays if you can avoid it.
If your amended return was rejected or needs more information
The Comptroller will mail you a formal notice if your amended return cannot be processed as filed. This notice will arrive at the address you listed on Form 502X. Read it carefully — it will explain exactly what is wrong or what documents you need to send. Common reasons for rejection include math errors, missing signatures, or conflicting information between your federal and state returns.
Follow the instructions in the notice. Usually you will need to send corrected documents or additional paperwork back to the Comptroller by mail. Include a copy of the rejection notice with your response so the office can match it to your file. Mail your response to the address listed in the notice, not to a general Comptroller address. Processing will restart once the Comptroller receives your corrected submission, and you should expect another 4 to 8 weeks for a decision.
Frequently Asked Questions
Can I check my amended return status by phone?
No. The Maryland Comptroller does not provide status checks by phone. You must use the online tool at marylandtaxes.gov. You can call the Refund Unit at 410-260-7801 only if your refund is more than 10 business days late after the issue date, or if you received a rejection notice and need clarification.
What if I filed my amended return electronically but the website says it was not received?
Contact the tax software or tax professional you used to file. Ask them to confirm the return was transmitted successfully and to provide you with a confirmation number. If they confirm it was sent, wait 48 hours and check the website again. If the Comptroller still shows no record after 48 hours, have your preparer resubmit the return or contact the Comptroller's office with your confirmation number.
How long does it take to get a refund after I send in additional documents the Comptroller requested?
Once the Comptroller receives your additional documents, processing typically takes 4 to 8 weeks. Mail delivery to Annapolis can take 5 to 7 business days, so the total time from when you mail your response to when you receive your refund is usually 5 to 11 weeks. Check the status website every two weeks after you mail your documents.
Will I get interest on my amended return refund?
Maryland does not pay interest on amended return refunds. You receive only the refund amount itself. If your amended return results in a refund, the Comptroller will not add interest even if processing takes longer than expected.
What if my amended return refund was supposed to go to direct deposit but I changed banks?
If your bank account information is no longer valid when the Comptroller tries to deposit your refund, the deposit will be rejected and the Comptroller will mail you a check instead. This adds 7 to 10 days to your delivery time. To avoid this, update your bank account information before you file your amended return if you know your account will close or change before processing is complete.
