How to Appeal Your Property Tax Assessment: A Step-by-Step Walkthrough

Why You Should Review Your Notice of Appraised Value

When you receive your annual Notice of Appraised Value from your county tax assessor, check it carefully. Assessors rely on mass appraisal algorithms that often fail to account for deferred maintenance, structural defects, or local neighborhood valuation disparities.

Step 1: Check the Deadline

Every county sets a strict deadline to file a formal protest — typically 30 days after receiving your notice, or by May 15th. Missing this deadline forfeits your right to appeal for the current tax year.

Step 2: Gather Evidence & Comparable Sales ("Comps")

Winning an appeal requires evidence. Request 3 to 5 recent sales of similar homes in your immediate subdivision that sold for less than your home's assessed market value prior to January 1st.

Step 3: Document Physical Conditions

Take clear photos of foundation cracks, roof leaks, outdated plumbing, or unpermitted additions on neighboring properties that negatively impact your parcel's true market value.

Step 4: Attend the Informal Conference & Formal ARB Hearing

Most disputes are settled informally with a county staff appraiser during an informal meeting. If an agreement is not reached, present your evidence to the independent Appraisal Review Board (ARB).
