Nassau County Terms & Conditions

Property Tax Grievance Authorization — Nassau County

Nassau 2028/29

Eligibility

You may sign this agreement if you are in any one of these four categories:

A) You own the property listed below or otherwise bear the responsibility for the payment of taxes;
B) You are the authorized agent for a person in category A;
C) You are in a contract to purchase the property you wish to file for; or
D) You are the administrator or executor of the estate of the late homeowner.

In accordance with NYS law, you may cancel without penalty within three days of signing this agreement.

Fees

Our fee is half (50%) of your first year's Property Tax Savings (2028/29 — one tax year).

If a refund for overpaid taxes is issued, ZapMyTax is authorized to negotiate, collect, deposit refund, and deduct fees therefrom. Any balance will be promptly dispersed to the Taxpayer.

Payments are considered late after 60 days from the original invoice and will be charged a late fee of 1.5% interest per month. Reasonable attorney and collection fees are charged on balances older than 90 days.

ZapMyTax, at its option, may submit its claim to a ZapMyTax-selected arbitrator. ZapMyTax shall advance any arbitration fees, but the arbitrator shall award such fees to the prevailing party.

ZapMyTax reserves the right to bring suit in the courts located in Nassau County; except if ZapMyTax demands arbitration, Nassau County courts shall have exclusive jurisdiction of any dispute/action relating to this agreement.

I agree in the event I sell or move out of the subject property, this agreement will survive the sale and I will remain responsible for any fees incurred unless I have the purchaser assume responsibility for this contract in writing.

Designation of Representative

I fully authorize ZapMyTax, an independent company, to act as our representative/agent in an application to challenge my Property Tax Assessment for the 2028-29 Assessment Roll at any proceeding, judicial, or otherwise including Article 7 of the New York Real Property Tax Law.

NYS charges a $30 fee on all appeals. During any assessment review process, ZapMyTax will make reasonable efforts to communicate the terms of any offer of settlement made by the County.

I am not required by law to use a tax reduction service to file and/or receive an assessment reduction.

By signing, the undersigned certifies that they are an aggrieved party within the meaning of Real Property Tax Law and hereby authorizes ZapMyTax to act as their agent/representative to file with the Nassau County Assessment Review Commission. — Version: 22.02
