How to Appeal Your DC Property Tax Assessment

Most DC homeowners have received their property tax assessments, and those who disagree can appeal. To do so, file electronically by April 1 or within 45 days for new owners. Contact your assessor for clarification on the assessment. Gather specific evidence to support your appeal, which can be based on market value, equalization, classification, or property condition. If denied, appeal to the Real Property Tax Appeals Commission within 45 days, and as a last resort, to the DC Superior Court.
