What is a property tax appeal?
A property tax appeal is a formal challenge to the assessed value of your property as determined by your local tax assessor. If your property is overassessed, you may be paying more in property taxes than you legally owe.
How to appeal your property tax assessment
Property tax appeal deadlines are strict and vary by state — typically between 30 and 90 days from when you receive your assessment notice. In many states, the deadline is May 15 or within 30 days of the assessment notice. Missing this deadline usually means waiting until next year.

Property / Tax Appeals in Maryland
Property and tax appeals in Maryland are essential for homeowners and businesses who believe their assessments are inaccurate or unfair. Issues such as inflated property valuations, incorrect classifications, or discrepancies in tax bills can lead to significant financial burdens. Maryland law provides a clear and structured process for appealing these decisions, ensuring that taxpayers have the opportunity to challenge assessments and seek equitable adjustments. Understanding these appeal mechanisms is crucial for protecting your property rights in Maryland.
Maryland’s property tax appeal process is primarily governed by the Maryland Tax-Property Code. Specifically, Maryland Tax-Property Code § 14-509 (2025) allows taxpayers to appeal a value or classification in the notice of assessment. Further appeals can be made to the Maryland Tax Court under Section 14-512. The Department of Assessments and Taxation (SDAT) is responsible for property valuations, and their appeal process is outlined in detail. Recent legislative updates ensure that appeals are heard in a timely manner and decisions are based on presented evidence, reinforcing fairness in Maryland’s property tax system.
If you need to appeal a property or tax assessment in Maryland, the Maryland Department of Assessments and Taxation (SDAT) is the initial point of contact. You can file an appeal online through their portal at [assessmentappeals.dat.maryland.gov](https://assessmentappeals.dat.maryland.gov/) within 45 days of the notice date. For further appeals, the Maryland Tax Court serves as an independent administrative agency that hears appeals from decisions of the property tax assessment appeal boards. While there isn't a direct phone number for the Tax Court for initial inquiries, the SDAT can guide you through the process. The Attorney General of Maryland also handles broader consumer protection issues related to property, accessible through their complaint portal at [oag.maryland.gov/i-need-to/Pages/business-complaints.aspx](https://oag.maryland.gov/i-need-to/Pages/business-complaints.aspx).
The process for a property or tax appeal in Maryland typically involves four steps: first, review your assessment notice carefully and identify any discrepancies; second, gather all supporting evidence, such as comparable sales data, appraisals, or repair estimates; third, file a formal appeal with the Maryland Department of Assessments and Taxation within the specified timeframe; and fourth, if necessary, appeal the decision to the Maryland Tax Court.
