All MD Comptroller Branch Offices Closed – Taxpayer Help Available by Phone or Email


All MD Comptroller Branch Offices closed throughout the state until further notice. Taxpayers have many options to complete their tax returns. They can still file electronically and have their questions answered via phone or email. We have extended nearly every deadline for payment of state taxes to help families facing employment challenges and to keep cash flowing in our economy, as well as to reduce the volume of assistance provided by our taxpayer services agents. Taxpayers are urged to file their Maryland state income tax returns electronically, including the use of direct deposit for refunds. Taxpayers also can email their questions to or call 1-800-MD-TAXES for help weekdays from 8:30 a.m. to 7 p.m.
