Our Locations

“Due to the new regulations set forth by Governor Hogan on December 17, 2020 to prevent the spread of COVID-19, along with continuing efforts to keep state employees and the customers they serve safe, there is a temporary suspension of in-person customer service operations at our facilities. Comptroller of Maryland branch offices are available for virtual appointments only. Taxpayer Assistance is available via email taxhelp@marylandtaxes.gov or by calling 1-800-MDTAXES. Our agents are standing by to help you.


  • Virtual appointments must be scheduled using the online appointment scheduler.
  • The Taxpayer must have internet access and able to connect with “Microsoft Teams”.
  • Virtual appointments can be accessed using the camera on your computer or cell phone.
  • Once an appointment is selected, the individual will receive an e-mail with instructions and the “invite link” to their virtual meeting. Each link can only be used one (1) time.
  • Please join, 5 minutes before your scheduled virtual appointment time.

For general information and free Maryland income tax assistance call Taxpayer Services at 410-260-7980 from Central Maryland, or 1-800-MD-TAXES (1-800-638-2937). Assistance is available 8:30 a.m. - 4:30 p.m., Monday through Friday.
