Step 1: confirm the deadline and forum
Find the appeal window on your assessment notice or official assessor, appraisal district, board of review, or tax office website. Missing the deadline can lock in the assessment for the cycle.
Step 2: check the property record
Review square footage, land size, building class, finished basement, bedroom and bathroom counts, condition, improvements, and exemptions. Clear errors are often the simplest evidence.
Step 3: gather comparable evidence
Strong appeals usually compare your home with similar properties, not with random cheaper homes. Focus on proximity, sale date, size, age, style, condition, and location.
Step 4: write and file the appeal
Use the local form and attach a concise explanation, your requested value, comparable evidence, and any photos or documents that support condition or record corrections.
