The National Taxpayers Union Foundation estimates that 30 to 60 percent of US residential properties are overassessed — meaning your county thinks your home is worth more than it actually is, and you're paying taxes on a number that doesn't reflect reality. County assessors work with mass appraisal models, incomplete data, and tight deadlines. Errors are not the exception. They're the norm.
The good news: you have the legal right to appeal your property tax assessment in every state. Homeowners who do appeal win reductions 40 to 60 percent of the time. A 10 percent reduction on a $400,000 home at a 1.5 percent tax rate saves $600 per year — compounding over every year until the next reassessment cycle. The system is designed for you to challenge it. You just have to do it.
A property tax appeal letter — also called a tax protest letter, assessment grievance, or notice of appeal depending on your state — is a formal written document you submit to your county's Board of Assessment Appeals, Board of Equalization, or Appraisal Review Board challenging the assessed value of your property. The letter must cite your legal basis for appeal, present evidence that your property is overvalued, and request a specific reduced assessment.
Most states call this the same basic process but use different vocabulary. Texas calls it a "protest." New York calls it a "grievance." Connecticut calls it an "appeal." Regardless of the name, the substance is the same — you present evidence that your home is worth less than the county thinks, and you ask them to reduce your assessment and your tax bill accordingly.
The strongest evidence in any property tax appeal is comparable sales — recent arm's-length sales of similar properties in your neighborhood that sold for less than what your assessment implies about your home's market value. Three to five solid comps, well-presented, win most residential appeals. TaxFight structures your comparable sales into a formal legal argument that addresses your state's specific assessment standards.
Additional evidence that strengthens an appeal includes errors in the assessor's property record (incorrect square footage, wrong bedroom count, basement recorded as finished when it isn't), documented condition issues (needed repairs, flood damage, structural problems), and assessment inequity — showing that similar neighboring properties are assessed at significantly lower values. TaxFight covers all of these in its form and generates a letter that addresses every applicable ground.
Property tax attorneys typically charge a percentage of your first year's savings — often 25 to 50 percent — plus filing fees. On a $600 annual savings, that's $150 to $300 going to the attorney. TaxFight generates the same quality appeal letter for a flat $39 with no percentage of savings, no retainer, and no billable hours. For most residential appeals, you don't need an attorney — you need a well-written letter with solid evidence.
TaxFight covers all of them in a single letter that addresses every applicable ground.
