Build Your Case for a Property Tax Appeal
Your assessed value jumped. The number doesn't match what similar houses on your street are selling for. You have comparable sales, photos of the cracked foundation, maybe an independent appraisal. Now you need to put it all together so the tax board can see what you see.

For property owners and the professionals who represent them
For property owners
You opened your assessment notice and the number doesn't add up. The house down the street sold for $80,000 less than what the assessor says your home is worth. You have the data -- now make the tax board see it.
- Organize comparable sales with labeled exhibit numbers
- Combine photos, appraisals, and repair estimates into one binder
- Print copies for the tax board, the assessor, and yourself
- No legal software or training required
For tax appeal attorneys and consultants
You handle dozens of assessment challenges each cycle. Some are single-family homes with five comparable sales. Others are commercial properties with income approach analyses, environmental reports, and 30 pages of financial data. You need consistent exhibit formatting across the entire caseload.
- Batch stamp comparable sales packages and appraisals in one session
- Create combined binders with table of contents for each appeal
- Maintain uniform formatting across multiple client cases
- No server uploads -- client financial data stays on the device

ExhibitPrep runs entirely in your browser. Tax assessment notices, appraisal reports, purchase price documentation, income statements for commercial properties -- none of it touches a server. No cloud upload, no third-party storage, no account required. Your financial information stays where it belongs.
When a tax appeal might not be worth it
If your assessment went up 3% in a year when every house on the block went up 3%, you probably don't have a case. But if your assessed value jumped 20% while comparable homes sold for less, or your property has a structural issue the assessor missed, organized exhibits with comparable sales data are how you win at the tax board.

Property tax appeal FAQ
What evidence do I need for a property tax appeal?
The strongest property tax appeals include comparable sales data showing similar properties that sold for less than your assessed value, an independent appraisal from a licensed appraiser, photographs documenting property condition issues such as foundation cracks or roof damage, repair estimates from licensed contractors, your tax assessment notice showing the disputed value, and prior year assessment history showing any sudden jumps. Under the 14th Amendment Equal Protection Clause, your property cannot be assessed at a higher ratio of market value than comparable properties in your jurisdiction.
How long do I have to file a property tax appeal?
Filing deadlines vary by state. In New Jersey, N.J.S.A. 54:3-21 gives property owners 45 days after the county tax list is finalized (typically April 1, making the deadline May 15) to file with the County Tax Board. In Texas, Property Tax Code section 41.41 allows protests to be filed by May 15 or within 30 days of receiving the appraisal notice, whichever is later. Missing the deadline means waiting until the next tax year, so check your state deadline immediately after receiving your assessment notice.
Are my financial documents safe in ExhibitPrep?
Yes. ExhibitPrep processes all files in your browser. Tax assessment notices, appraisal reports, financial statements, and property photographs are never uploaded to any server. Your files stay on your device from upload through download. This matters for property tax appeals because the documents often contain assessed values, purchase prices, and other financial information you may not want stored on third-party servers.
Can I appeal my property tax assessment without an attorney?
Yes. Most property tax appeals at the county or local board level are handled by property owners without attorneys. Tax boards are administrative bodies, not courts, and their procedures are designed for self-represented appellants. Organized exhibits with comparable sales data and clear labels help the board follow your argument. An attorney or property tax consultant becomes more valuable if you escalate to the state tax court after an unfavorable board decision.
What are comparable sales and how many do I need?
Comparable sales are recent transactions of properties similar to yours in size, age, condition, and location. Tax boards typically expect 3 to 5 comparable sales that closed within the past 12 months and are within a half-mile to one-mile radius of your property. Each comparable should include the sale price, sale date, property address, square footage, lot size, and any adjustments for differences such as extra bedrooms, a pool, or a garage. The closer the comparable is to your property in features and proximity, the stronger it is.
What happens if I win my property tax appeal?
If the tax board reduces your assessed value, your property taxes are recalculated at the new lower assessment. Most jurisdictions issue a refund or credit for any overpayment in the current tax year. In some states, the reduced assessment carries forward to future years until the next reassessment cycle. Keep copies of your stamped exhibits and the board decision, as you may need them if the assessor attempts to raise the value back in subsequent years.
