How to Appeal in Maryland
Check your assessment notice
Your county assessor mails assessment notices — usually in spring. The notice shows your assessed value and the appeal deadline. In most states you have 30–90 days from the notice date.
Gather comparable sales
Find 3–5 similar properties in your neighborhood that sold recently at prices below your assessed value. Use Zillow, Redfin, or your county recorder's public records. The more recent and similar the sales, the stronger your case.
File your formal appeal
In Maryland, you file with the Property Tax Assessment Appeals Board. File written appeal with the local Property Tax Assessment Appeals Board within 45 days of the Notice of Assessment. Maryland reassesses properties on a 3-year cycle. File before 45 days after assessment notice.
Present your evidence at the hearing
Show up with your comparables. Be calm and factual. You don't need a lawyer. Appeals boards are accustomed to homeowners representing themselves. Simply demonstrating that comparable properties sold for less than your assessment is often enough to win a reduction.
