Property owners in Washington, District of Columbia can formally protest their real property assessment through the Office of Tax and Revenue to seek a revised valuation. This guide explains who may appeal, common grounds, the basic steps to file a protest, and what to expect at review or hearing. For official filing instructions and deadlines consult the Office of Tax and Revenue real property assessment page (Real Property Assessments)[1].

Who can appeal and common grounds

  • Owners of record, legal representatives, and authorized agents may typically protest an assessment.
  • Grounds include incorrect property characteristics, comparable sales showing lower market value, errors in lot or building data, and exemptions or coding mistakes.
  • Evidence commonly used: recent sales, appraisal reports, income/expense statements (for income properties), photographs, and tax maps.
Gather clear, dated evidence before you file; hearsay or unsupported claims are unlikely to change an assessment.

  • Appeal and review routes: administrative review/hearing through OTR with possible subsequent judicial review in local court; exact time limits for each stage are not specified on the cited page.
