Received a Property Assessment Bill in Maryland? Here’s How to Appeal

If you’ve recently received your Real Property Assessment bill and believe your home’s assessed value is incorrect—whether too high or too low—you have the right to appeal the decision.

In Maryland, property assessments are managed by the Maryland Department of Assessments and Taxation (SDAT). As a homeowner, you have the right to challenge your assessment, but it’s important to act quickly and understand the steps involved.

Step 1: File a Supervisor’s Level Appeal

You can file an initial appeal—called a Supervisor’s Level Appeal—within 45 days from the date listed on your assessment notice. This appeal can be submitted in writing and is typically reviewed by your local SDAT office.

Step 2: Appeal to the Property Tax Assessment Appeal Board (PTAAB)

If you’re not satisfied with the outcome of the Supervisor’s Level appeal, you can appeal to the Property Tax Assessment Appeal Board (PTAAB) in your county. This must be done within 30 days of receiving your Final Notice of Assessment. At this level, you may submit a written appeal or request an in-person hearing before the board.

Step 3: Appeal to the Maryland Tax Court

Still disagree with the outcome? You can escalate the matter by appealing to the Maryland Tax Court. This must also be done within 30 days of receiving the PTAAB’s decision. Note that proceedings in Tax Court are exclusively in-person.
