Why Appeal Your Property Tax Assessment?

Property taxes are based on your home's assessed value, not its market value. If your assessment is too high, you're paying more than you should.

Common reasons to appeal:

💡 Did you know? Studies show that 30-50% of properties are overassessed. Appealing can save you hundreds or thousands per year.

Step 1: Review Your Assessment Notice

Your county tax assessor sends an Assessment Notice annually (usually January-March). This document shows:

Step 2: Research Comparable Properties

To win your appeal, you need evidence that your assessment is too high. Collect:

  1. Sales data for similar homes in your neighborhood (past 6-12 months)
  2. Assessments of comparable homes (check county website)
  3. Independent appraisal (if your home value is disputed)
  4. Photos & repair estimates for property defects

Step 3: File Your Appeal

Each county has its own appeal process. Typically:

  1. Download the appeal form from your county website
  2. Complete all required fields (property ID, owner info, reason for appeal)
  3. Attach evidence (comparable sales, photos, appraisal)
  4. Submit by the deadline (often March-April)
  5. Pay the filing fee (usually $25-$100, varies by county)

Step 4: Prepare for Your Hearing

Most appeals involve a hearing before the Board of Review or Assessment Appeals Board. Tips:

Step 5: Understand the Decision

The board will notify you of their decision (usually within 30-60 days):

State-Specific Appeal Deadlines (2026)

Note: Deadlines vary by county. Check with your local tax assessor's office.

Tips for a Succesful Appeal

  1. Start early: Don't wait until the deadline. Gather evidence in advance.
  2. Be organized: Label al evidence clearly. Create a binder with tabs.
  3. Focus on market value: The board cares about what similar homes sold for, not your personal hardships.
  4. Consider hiring a professional: If your assessment is very high ($500k+), a tax consultant may be worth it (fee: $200-$500).
  5. Don't give up: If denied, you can appeal to the state. Some homeowners win on the second try.

Frequently Asked Questions

Can I appeal if I just bought my home?

Yes! In fact, your purchase price is strong evidence. If you bought for $300,000 but your assessment is $350,000, you have a strong case.

Will my taxes go up if I lose the appeal?

No. The board can only lower your assessment, not raise it (in most states). You have nothing to lose by appealing.

How long does an appeal take?

Typically 3-6 months from filing to final decision. Some counties have faster proceses (30-60 days).
