Compare flat-fee and percentage-of-savings pricing for Nassau County property tax grievance services and see how the fee structure changes what a homeowner keeps.

Homeowners may encounter a fixed fee, a fee tied to savings, or a combination of charges. The useful comparison is the total amount you may pay if the filing succeeds—not just the advertised entry price.
Percentage-of-savings example
If a hypothetical service charged 50% of first-year savings, $2,000 of annual savings would produce a $1,000 fee and $3,000 of annual savings would produce a $1,500 fee. That is an illustration of the math, not a claim that every provider uses the same percentage or billing method.
How GrieveItNow charges
GrieveItNow charges a $99 flat fee for Nassau County research, preparation, and filing. We do not take a percentage of the savings and do not automatically renew the service for the next grievance cycle.
Official filing dates and procedural references are based on current Nassau County Assessment Review Commission and Department of Assessment materials. County notices and rules control if they change. Educational information is not a guarantee of a reduction.
