FAQ: Business Tax Audits

How do I know that the person who comes to audit me really works for the Comptroller's Office?

Comptroller's Office auditors will show that taxpayer a photo I.D. on their first visit. We urge taxpayers who have any doubt at all about the authenticity of an I.D. to telephone us immediately at 410-767-1501 in the Baltimore area or 1-800-492-1752 from elsewhere in Maryland.
