What Documents Do You Need for a Property Tax Appeal?

Quick answer: A strong appeal file usually includes the assessment notice, property record card, comparable sales, photographs, proof of factual errors, and any appraisal, inspection, or repair evidence that materially affects value.

The goal is not to create the thickest packet. The goal is to make the value issue easy to understand.

1. Assessment notice

Keep the complete notice, including mailing date, valuation figures, exemptions, appeal instructions, and deadline. This is the document that defines what is being challenged.

2. Assessor property record

Obtain the property card or assessment record showing how the assessor describes the parcel and improvements. Mark factual errors and attach evidence supporting each correction.

3. Comparable sales

Use several strong closed sales with basic details: address, sale date, price, size, style, condition, and relevant amenities. Explain why each sale is comparable.

4. Photographs

Photographs are especially useful for deferred maintenance, interior condition, location problems, damage, or differences between your property and a renovated comparable.

5. Estimates, inspections, and reports

Contractor estimates, inspection reports, engineering reports, or environmental information can provide objective support when property condition affects value.

6. Appraisal or market analysis

If you have a recent appraisal that aligns with the relevant valuation date, include it. If not, a concise comparable-sales analysis may still be useful.

7. A one-page summary

Put your requested value and strongest reasons on one page. This gives the reviewer a map of the evidence that follows.
