Maryland is assessed by the state, not by your county. The Department of Assessments and Taxation (SDAT) values every property through a local Supervisor of Assessments office β there is no appraisal district here.
SDAT reassesses one third of the state each year, on a three-year cycle. If your group came up this year, you got a notice. If it did not, you can still appeal β the route is just different.
If you received a reassessment notice, you have 45 days from the notice date to appeal. That is the main route, and SDAT takes it online.
If you did not, you can file a Petition for Review by January 1 before the tax year begins. New owners get their own appeal window after purchase.
Maryland assesses at 100% of market value, then phases increases in over the three years of the cycle. So there are two numbers on your notice: the full new value, and the lower phase-in value you are actually taxed on this year.
An appeal argues the full value. But your bill only moves if the value we win lands below the phased-in figure. That gap varies enormously β we have measured neighbourhoods where it is zero and others where nearly the whole increase is still phasing in.
We calculate this before we recommend anything, because a reduction that does not cross the phased-in number is a win on paper and nothing on your bill. You should know which one you are getting.
We pull recent sales from MLS and public records, compare them against the value SDAT put on your property, and show you the gap. You get the comparable sales, the value we can support, and the honest number for what it saves you this year.
Appeals go first to your local assessment office, then to the Property Tax Assessment Appeal Board (PTAAB) for your county, and from there to the Maryland Tax Court.

We cover all 23 Maryland counties and Baltimore City.
Maryland assesses at 100% of market value (Tax-Property Art. 8-104), so the appeal argues the value itself. There is no uniformity or unequal-appraisal ground here β that is a Texas and Georgia remedy.
Three recent sales support a market value of $612,000:
The saving is calculated against the phased-in value, not the full one. Maryland spreads increases across the three-year cycle, so this owner is taxed on $654,133 rather than $675,200. Winning $612,000 clears the phased-in figure by $42,133 β that gap, not the headline reduction, is what reaches the bill. Where a proposed value lands above the phased-in number, the bill does not move at all, and we say so before you pay.
45 days from the date on your reassessment notice. If you did not get one this cycle, file a Petition for Review by January 1 before the tax year starts. New owners get a separate window after purchase.
Maryland reassesses a third of the state annually on a three-year rotation, so two years out of three you will not receive one. That does not block an appeal β it just changes the form and the deadline.
Maryland assesses at 100% of market value but phases increases in across the three-year cycle. The full value is what an appeal argues against; the phased-in value is what you are taxed on this year. A reduction only lowers your bill if it drops below the phased-in figure, so we check that gap before recommending an appeal.
Your local Supervisor of Assessments first. If that does not resolve it, the county's Property Tax Assessment Appeal Board (PTAAB), then the Maryland Tax Court.

No. Comparing your assessment to your neighbors' is a Texas and Georgia ground. Maryland assesses everyone at 100% of market value on the same cycle, so the argument here is simply that the market value is wrong β proven with recent sales.
