Property-tax appeals in Maryland
Deadlines, evidence, and a packet you file yourself — for homes, multifamily, and commercial property in Maryland.
State rules verified from public sources| Deadline rule | Submit a written appeal to the Supervisor of Assessments on or before 45 days from the date of the notice of assessment (Md. Code, Tax-Property Article 14-502); a new owner who took title after January 1 may appeal within 60 days of the transfer |
|---|---|
| First hearing body | Supervisor of Assessments (SDAT, first level); then the county Property Tax Assessment Appeals Board (PTAAB); then the Maryland Tax Court |
Maryland reassesses on a triennial (three-year) cycle; in the two non-reassessment years an owner may instead file a Petition for Review by the first working day after January 1 (SDAT). The PTAAB appeal must be filed within 30 days of the Supervisor's final notice, and a Tax Court appeal within 30 days of the PTAAB order. Commercial note from SDAT: under Tax-Property Article 14-508, an owner of income-producing property who fails to submit required income and expense information may not challenge the value on a capitalization-of-income basis beyond the Supervisor's level. No filing fee was stated in the sources checked.
What wins in Maryland
Homes are argued on comparable sales and uniformity. Income property is argued on the income approach — rent roll, expenses, and a supported cap rate. The packet builds the argument that matches your property type, with your evidence organised as exhibits.
