Blocked Tax Preparers


Audience: Individuals, Businesses

As part of our effort to combat fraud, the Comptroller's Office blocks suspicious tax returns and suspicious tax preparation businesses after being identified by the Comptroller's nationally recognized fraud unit using state-of-the-art technology. Since taking office in 2007, the Comptroller's team has identified and blocked more than 88,000 fraudulent returns and intercepted and denied $190.2 million worth of fraudulent refunds.

If taxpayers suspect fraud, they are asked to immediately report the issue to the Comptroller's Office by calling 1-800-MD-TAXES (1-800-638-2937) or 410-260-7980 in Central Maryland or by emailing taxhelp@marylandtaxes.gov.
