Homeowners who believe their Catonsville home is over-assessed have the right to file a appeal directly with Maryland Department of Assessments and Taxation before the 45 days from notice deadline.

Catonsville Property Market Context
The property tax picture in Catonsville is shaped as much by Maryland statewide policy as by anything unique to a city.
Maryland market character
Maryland reassesses on a three-year cycle (each property every third year), and the state assesses at 100% of full cash value. A Homestead Tax Credit caps annual increases, but the underlying assessment still matters for exemptions and at resale.
How Maryland handles appeals
Maryland homeowners appeal to the Supervisor of Assessments, then the Property Tax Assessment Appeal Board, then Tax Court. The state is protest-friendly, and appeal evidence standards are well-defined.
When to file in Catonsville
You have 45 days from the date of your reassessment notice to file an appeal. Notices mail in late December for the following tax year.
