Most New York property owners are overassessed and don't know it. We find out for you — and if your taxes can be reduced, we fight to lower them.
Three simple steps between you and lower property taxes.
Sign a simple authorization form (about 2 minutes). No obligation, no upfront payment.
We review your assessment against current market values and file with your municipality's Board of Assessment Review before the annual deadline.
You pay nothing until you see the savings. No reduction = no fee, ever.
Enter your property address and we'll look up your current assessment and estimate your potential savings.
We use property data to estimate your savings. This is an estimate only — actual results may vary.
Contact us to confirm your specific deadline — missing it means waiting until 2027.

Questions?
A formal complaint to your local Board of Assessment Review challenging your property's assessed value. If successful, your assessment is reduced, which lowers your annual tax bill.
No. New York State law prevents assessments from being raised as a result of a grievance filing. There is no downside to filing.
Nothing upfront. We work on a contingency basis — our fee is a percentage of your first year's savings. If your taxes are not reduced, you owe us nothing.
Typically a few months for residential properties after the grievance is filed. If the Board denies relief, we can pursue Small Claims Assessment Review (SCAR) at no additional upfront cost. Commercial cases may require additional proceedings.
Very little. We handle the filings, research, and hearings. We'll keep you informed at every step and notify you of any settlement offers or decisions.
Yes — office buildings, retail, industrial, warehouses, and apartment complexes all qualify. Commercial properties often have the highest savings potential.
No. Win Your Tax Appeal is not a law firm and does not provide legal advice. We are an authorized non-attorney representative under RPTL §524. For matters requiring court proceedings, cases are referred to licensed New York attorneys.
