I Filed A Return

You filed your Maryland tax return, but you may have received an income tax notice from the Comptroller's Office if:

  • You did not pay the full amount due with your return. 
  • A correction was made to your return when it was processed which resulted in additional tax due.
  • Interest and/or Penalty were assessed for late payment of tax due or for underpayment of estimated tax.
  • Your return was adjusted based on an audit which resulted in additional tax due.

Look up your notice under "I Received a Notice" to learn more about the notice you received and what to do next. If you have questions about the notice you received, you may call the number provided on the notice you've received to speak with a representative.

If You Believe Have Already Filed a Maryland Return for the Year in Question

If you lived in Maryland during the year indicated on your notice and you believe you have filed a Maryland income tax return, please provide a copy of the return along with all attachments such as W-2's and 1099(s), also provide a copy of the cancelled check(s) of any payment made with your return.

If you have questions call (410) 767-1966 or toll free 1 (800) 648-9638. Please don't assume the problem will go away, even if you believe the notice is incorrect.
