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.
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.
TaxDrop currently operates in Texas. See our Texas property tax guide.
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.
Not yet. TaxDrop currently serves Texas only. Join the waitlist on this page and we'll let you know when we launch in Maryland.
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.
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.
