Taxpayer Services

Beginning October 4, 2021, out of an abundance of caution to keep our employees healthy and safe, the Comptroller of Maryland is limiting branch operations to scheduled appointments only. Walk-ins will no longer be accepted at any of our regional offices until further notice. Taxpayers can schedule in-person or virtual appointments easily by visiting our Locations page. Taxpayer assistance is also available via email or by calling 1-800-MDTAXES. Our agents are standing by to help you.
