How Property Tax Protests Work: The Complete Process From Start to Finish
TL;DR
A property tax protest (called an "appeal" in most states) is a formal challenge to your property's assessed value. You file a protest within the deadline (usually 30-90 days from the assessment notice), present evidence that your value is too high, and a hearing officer or board decides whether to lower it. The process is free or costs a small filing fee. You do not need an attorney. Over 50% of homeowners who protest get a reduction. The key evidence is comparable sales showing that similar properties are worth less than your assessed value.
Who Can Protest
Any property owner can protest their assessment. You do not need a reason beyond believing the value is too high. Some states (notably Texas) also allow protests on the basis of "unequal appraisal," meaning your property is valued higher than comparable properties regardless of absolute market value.
When to File
Deadlines vary by state:
| State | Filing Deadline |
|---|---|
| Texas | May 15 or 30 days after notice (whichever is later) |
| California | July 2 - November 30 |
| Florida | 25 days after TRIM notice |
| Illinois | 30 days after township assessment window opens |
| New York | Grievance Day (4th Tuesday in May, varies) |
| Ohio | March 31 |
| Georgia | 45 days from assessment notice |
The Process
- Review your assessment: Check the value and property details for errors
- Gather evidence: Comparable sales, property condition photos, independent appraisals
- File the protest: Submit the form (online, mail, or in person) before the deadline
- Informal hearing: Many jurisdictions offer an informal meeting with the assessor first
- Formal hearing: Present your case to a board or hearing officer
- Decision: The board rules to maintain, reduce, or (rarely) increase your value
- Further appeal: If you disagree, you can appeal to a higher body or court
Best Evidence
- Comparable sales: Recent sales of similar homes at lower prices than your assessment
- Property condition: Deferred maintenance, needed repairs, functional obsolescence
- Data errors: Wrong square footage, room count, or features
- Unequal appraisal: Similar homes in your area assessed at lower values (Texas and some other states)
What It Costs
Filing a protest is typically free or costs $15-$30. You do not need to hire an attorney or tax consultant, though you can if you prefer. The potential savings far outweigh any filing fee.
