Property tax assessments often surprise homeowners—sometimes by thousands of dollars—and most people don't realize they have the right to challenge them. If your assessment seems inflated compared to similar properties in your neighborhood, appealing is usually free or nearly free, with deadlines typically ranging from 30 to 90 days depending on your jurisdiction. Here's exactly how to navigate the process through your local Tax Assessor & Collector Office.
Understand Your Assessment Notice
Your Tax Assessor & Collector Office mails assessment notices annually, usually in spring or early summer. Read it carefully: it shows your property's assessed value, which differs from market value and directly impacts your tax bill. Common red flags include incorrect square footage, missing or added rooms, and wrong lot size. Cross-reference the details with your deed and recent appraisals—assessors rely on public records that are frequently outdated or contain errors.
Gather Documentation Before Filing
Pull together evidence that supports a lower valuation. This includes:
- Recent appraisals from licensed appraisers (costs range from $300–$600)
- Comparative market analyses (CMAs) showing similar properties selling for less
- Photos of property damage, deferred maintenance, or outdated systems
- Receipts proving your home lacks upgrades the assessment assumes (no updated electrical, HVAC, or plumbing)
- Assessment records from the past 3–5 years showing sudden jumps
- Sales data for comparable homes in your area within the last 12 months
The Tax Assessor & Collector Office bases assessments on public data, so if that data is wrong, your appeal has merit. If you've done major renovations or repairs post-assessment, document those separately.
Check Your Jurisdiction's Appeal Deadline
Deadlines are strict—missing them typically closes your case for that tax year. Contact your local Tax Assessor & Collector Office directly (not a third party) to confirm the deadline; it's usually 30–90 days from the notice date. Some jurisdictions allow online filing through their portal; others require in-person submission or certified mail. Ask whether your office accepts appeals by email, and request written confirmation of receipt if mailing documents.
File Your Appeal Formally
Most Tax Assessor & Collector Offices require a formal appeal form—request it directly or download it from the office website. Include:
- Your property address and parcel number
- The assessed value you dispute
- Your proposed value with supporting documentation
- A brief, factual explanation (one paragraph is sufficient)
- Copies (not originals) of your evidence
Keep it organized and concise. Assessors review dozens of appeals monthly; a clear, bullet-pointed case outweighs rambling explanations. Many jurisdictions now let you compare your assessment to 3–5 recent comparable sales directly on their website—use that data in your filing.
Prepare for the Hearing
If the Tax Assessor & Collector Office denies your initial appeal in writing, you typically have a second chance before a county board or review authority. This hearing is your opportunity to present evidence in person or by phone. Prepare a 5–10 minute presentation highlighting:
- Why the assessed value exceeds fair market value
- Specific comparable properties and their sale prices
- Any errors in the property record
- Photos or inspection reports showing property condition
Dress professionally and speak directly to the board members. Bring all original documentation and expect the assessor to defend their valuation. These hearings are less formal than court but still official proceedings.
Know the Timeline and Costs
From filing to final decision typically takes 2–6 months. There's rarely a filing fee (most jurisdictions waive it), though if you hire an attorney or professional appraiser, expect $500–$2,000 in costs. Many homeowners handle it alone successfully, especially if the error is obvious. If you win, you may owe nothing; if you lose, you can't appeal further at the Tax Assessor & Collector Office level—your next step would be circuit court, which is expensive.

Frequently Asked Questions
Q: How much can a property assessment change year to year? A: Most jurisdictions cap annual increases at 3–5%, though significant renovations or market reassessments can trigger larger jumps. Check your local tax code.
Q: What if my assessment is higher than my recent appraisal? A: A licensed appraisal is strong evidence in an appeal, especially if it's recent (within six months) and the appraiser used comparable sales data similar to your property type and location.
Q: Can I appeal if I just bought my home? A: Yes, but timing depends on your jurisdiction's reassessment rules. Some reassess at purchase; others grandfather prior assessments for a year or two. Ask your Tax Assessor & Collector Office immediately after closing.
