How to Appeal
Your Assessment

Every year thousands of homeowners overpay because of incorrect assessments. If your home is overvalued, you have a legal right to protest — and winning saves an average of $500–$2,000 per year, permanently.

Critical: The Filing Window Is Strict

You typically have only 30–90 days from the date on your assessment notice to file a formal appeal. After that window closes, you forfeit your right to challenge the value for the entire tax year. Check your notice's date immediately and mark your calendar.

2026 Strategy

The 5-Step Appeal Strategy

1

Audit Your Property Record Card

Visit your county assessor's website and pull up your property's record card. This document shows every characteristic the assessor used: square footage, bedroom/bath count, basement finish, lot size, and condition grade. Factual errors are the easiest wins — if your record says 4 bedrooms and you have 3, you have an immediate case.

💡 Tip: Even a 50 sq ft discrepancy can justify a reduction.
2

Research Comparable Sales (Comps)

Find 3–5 properties that are genuinely similar to yours — same neighborhood, similar lot size, age, style, and condition — that sold within the last 6–12 months. If their sales prices are lower than your assessed value, that's your primary evidence. Use Zillow, Redfin, or your county's recorded deeds to find comps.

💡 Tip: Focus on arm's-length sales only — foreclosure and estate sales may be excluded.
3

Document Negative Factors

Assessors typically assume your home is in "average" condition. If it's not — cracked foundation, aging HVAC, leaking roof, flood damage — document it. Photograph every defect. Get written estimates from licensed contractors for repair costs. Each documented issue supports a lower market value.

💡 Tip: A professional appraisal (~$400–$600) provides the strongest evidence but isn't always necessary.
4

File the Formal Protest

Download and complete your county's appeal/protest form. Attach your comparable sales data, property record discrepancies, and defect photos. Most counties now accept online filings. Keep a copy of everything and note your tracking/confirmation number. Some counties first offer an informal hearing with an appraiser before a formal board hearing — always try this route first.

💡 Tip: Be specific in your protest: state the value you believe is correct, not just that it's wrong.
5

Present Your Case at the Hearing

Bring printed copies of all your evidence. Be calm, brief, and factual. State your position: "I believe the market value is $X, supported by these 5 comparable sales." Present your evidence, answer questions, and let the data speak. You do not need an attorney for most informal hearings.

💡 Tip: Arriving prepared typically takes 15–20 minutes total hearing time.

Appeal FAQ

Can my taxes go UP after I appeal?
It's rare but legally possible — if a formal hearing reveals your home was underassessed, the value could increase. However, most assessors only present evidence to defend their original value, not to increase it. Informal hearings essentially never result in an increase.
How much can I realistically save?
Successful appeals typically reduce assessed values by 5–15%, translating to $300–$2,500 in annual savings depending on your local rate. The reduction is permanent until the next reassessment cycle (usually 1–4 years).
Do I need a lawyer or property tax consultant?
Not for most residential appeals. An informal hearing requires only your evidence and a clear statement of your position. Consultants and tax attorneys are worth considering for high-value properties ($1M+) or if you're appealing a commercial property.
What if I lose my appeal?
You can typically appeal to a higher board (State Board of Tax Appeals or Circuit Court) within 30–60 days. Some states also allow a fresh protest the following year when new assessment notices are issued.
How long does the process take?
Filing takes 30–60 minutes. An informal appraiser meeting is usually scheduled within 2–4 weeks. A formal board hearing may take 2–6 months. Most homeowners resolve at the informal stage, which is faster.
