How the Review Process Works

Generally, start with a request for informal review with the Assessing Department to correct apparent errors. If the Department issues a decision you disagree with, file a formal abatement application if available. After a final local decision, or if local remedies are exhausted, eligible taxpayers may appeal to the Appellate Tax Board for a hearing and binding determination.

• Evidence: comparable sales, certified appraisals, income/expense records for income properties.
• Hearings: the ATB schedules hearings and accepts written and oral evidence under its rules.
• Decisions: the ATB issues written decisions; municipal assessing offices adjust valuations where required.
