Frequently Asked Questions

What happens if I miss the deadline?

You’ll have to wait for next year’s filing window. Each county gives you only a short window to file: in Nassau it typically runs from early January to March 1, and in Suffolk it closes on the third Tuesday in May. The good news is you can file every year, so missing one deadline doesn’t lock you out for good. Apply now and we’ll have you ready for the next window.

Does it cost me anything to apply?

No. It costs nothing to apply and there’s no upfront fee. You only pay if we lower your taxes: our fee is 50% of your first year’s savings. No reduction, no fee. In some cases a $30 court fee and a $75 appraisal fee may apply.

Can I still file if I'm in a village?

Yes. If your home is in an incorporated village, you can still grieve your property taxes. Just know that village taxes require a separate grievance, filed directly with the village, and villages set their own deadlines.

What do I need to apply?

Just a minute of your time. Our application takes less than 60 seconds online, or you can apply by phone. Pick the application for your county (Nassau or Suffolk), then e-sign it online or download the PDF and send it to us by fax, email, or mail. You can apply if you’re the homeowner of record, under contract to buy the home, the estate of a deceased homeowner, or the trustee of a home held in trust.
