Why appeals work
NYC uses mass appraisal — a formula applied to hundreds of thousands of properties at once. Errors are inevitable. According to the National Taxpayers Union Foundation, 30–60% of residential properties are overassessed.
Your assessment is just an estimate. State law gives you the right to challenge it with evidence. Most homeowners never check — they assume the city got it right. Fewer than 5% ever file an appeal. That's why overassessments persist year after year.
The fix is simple: show that your assessed value is out of line with comparable properties. If the data supports it, the Tax Commission adjusts.
Three things that stop homeowners from filing
"What if my taxes go UP?"
They won't. An appeal can only lower your assessment or leave it unchanged. The Tax Commission cannot raise it as a result of your appeal.
"Will I have to go to a hearing?"
Almost certainly not. Most NYC appeals are resolved by mail review — no hearings, no face-to-face. You submit your TC108, they review it, you get a decision.
"Is it actually worth the effort?"
A successful appeal resets your bill for years. Even a modest reduction on a $500K property can save you $1,000+ annually. The TC108 takes minutes with our pre-filled form.
