Property Tax Appeals · Maryland
Appeal your property taxes
in Maryland.
Maryland is unusual: the state itself — the State Department of Assessments and Taxation (SDAT) — values every property, reassessing one-third of each county every year on a three-year cycle. When your reassessment notice arrives (late December), you have 45 days to appeal, starting with a supervisor’s-level hearing at SDAT, then the county’s Property Tax Assessment Appeals Board (PTAAB), and finally the Maryland Tax Court. In the two off-years between reassessments you can still file a petition for review rather than waiting for the next notice. At every level the question is the same — what the home was worth on the date of finality — and comparable sales evidence is what moves the number.
You have 45 days from the date on your reassessment notice to appeal. Notices mail in late December, so the window closes in early-to-mid February for most owners.
Assessment increases phase in over the three-year cycle, and the Homestead Tax Credit caps how fast your taxable assessment can grow — so read the notice carefully to see whether the market value or the phased/capped value is what’s actually driving your bill. The appeal contests the market value.
The evidence
Boards act on value,
not frustration.
However Maryland labels the process, the case underneath is identical: show what your home was actually worth on the assessment date. A licensed, USPAP-compliant appraisal — comparable sales, documented adjustments, a signed opinion of value — is that showing. Start with the $5 check to see if the numbers are on your side before you spend real money.
- Valued as of your assessment date — not today
- Comparable sales with adjustments and citations
- Signed by a state-licensed MD appraiser
- Phone walkthrough — no stranger in your home

45 days from the date on your reassessment notice. Notices go out in late December for the third of properties being reassessed that year.
Yes — Maryland allows a petition for review between reassessment years. It’s worth doing when the market has clearly fallen below your assessed value rather than waiting up to three years for the next notice.
A citizen panel hears your evidence of market value — comparable sales with adjustments, exactly what a licensed appraisal contains — and SDAT’s side. It’s informal, and well-documented cases do well there.
