New York Property Tax GuideGrieve and Lower Your New York Property Tax.
New York has one of the highest effective property tax rates in the country. The average New York homeowner pays about $6,900 in property taxes per year. Every one of them has the statutory right to file a grievance on Grievance Day, and most never do.
How the New York Grievance Process Works
- Find your assessment on the tentative assessment roll, posted May 1 in most localities.
- Gather comparable sales from the prior year, adjusted for size, condition, and location.
- File form RP-524 with the Board of Assessment Review before Grievance Day.
- BAR hearing (informal, 10 to 15 minutes). Present your comps.
- SCAR review (Small Claims Assessment Review) if denied, $30 filing fee, no lawyer required.
Grievance Day Deadlines by Region
- Most of NYS (upstate towns): Fourth Tuesday of May
- Nassau County: March 1 (ARC, Assessment Review Commission)
- Westchester County: Third Tuesday of June (varies by town)
- Suffolk County: Third Tuesday of May
- New York City: March 1 (1 to 3 family homes) / March 15 (other classes), NYC Tax Commission, form TC108/TC109
- Rochester, Syracuse, Buffalo: Vary, check city assessor
NYC is different. Do not look for Grievance Day in New York City, it does not exist. NYC uses the Tax Commission, with March 1 / March 15 deadlines and a distinct set of forms (TC108, TC109, TC150). The average NYC homeowner who successfully appeals saves more than $2,000 the first year.
When You Probably Qualify for a Reduction
- Your assessed value, divided by the equalization rate, exceeds recent comparable sales
- Similar homes on your block are assessed materially lower
- Your home has water damage, foundation problems, or deferred maintenance
- You bought your home below the current assessed market value
- You are in an area hit by a local market downturn

Can a grievance raise my assessment?
No. New York law caps the outcome at no change; a grievance cannot increase your assessed value.
Do I need an attorney to grieve?
No. RP-524 and SCAR are both designed for homeowners to self file. Over 60% of New York grievances are filed without representation.
How often can I file?
Every year. New York homeowners can grieve annually, regardless of prior year outcomes.
What about Nassau County homeowners?
Nassau runs on its own calendar. File with the Assessment Review Commission (ARC) by March 1. Nassau has one of the most active grievance ecosystems in the country, roughly 40% of homeowners file every year.
