County Executive Laura Curran’s Taxpayer Protection Plan
How TPP works:
County Executive Curran’s Taxpayer Protection Plan (TPP) provides property tax exemptions that will protect homeowners from significant immediate increases in their property taxes as a result of the recently-completed countywide property reassessment, which was necessary to fix the County’s broken and corrupt assessment system.
TPP will phase in increases in property value due to the reassessment, effectively spreading out any changes in property taxes over a five-year period starting with the 2020-2021 assessment roll.
For more information, an updated FAQ on TPP is available here.
Status of TPP:
County Executive Curran secured authorization for the phase-in plan from New York State in April 2019.
Although TPP has been authorized by the State, it must be passed by the Nassau County Legislature to be implemented.
The County Legislative Majority has been stalling since April 2019, refusing to allow a vote on the local legislation that will enact TPP and ease the tax burden of the reassessment.
Commercial property owners automatically will continue to have a five-year phase-in of their new values. Nassau’s residential property owners would be provided the same protection with the passage of the TPP. Also, a recently-released report by the New York City Advisory Commission on Property Tax Reform recommends that annual valuation changes for NYC residential properties be phased in over five years.
If approved by the County Legislature, homeowners would see the effects of the TPP in their school tax bill in October 2020 and their general tax bill in January 2021.
County Executive Curran recommends that residents contact their local legislator by calling 516-571-6200, ext. 7, to urge them to pass this crucial legislation.
How will TPP affect you?
To continue to provide transparency for taxpayers, the Department of Assessment in 2019 prepared Taxpayer Protection Plan statements for every homeowner. The TPP statements show hypothetical estimated property taxes for the 2020-2021 tax year and are available online here.
These estimates factor in:
- eligibility for tax exemptions including Senior Citizen, STAR, Enhanced STAR and Veterans;
- County, town, special district and school district tax levies for the 2018-2019 tax year;
- successful grievances with the Assessment Review Commission (ARC) for 2018-2019 and 2019-2020 assessment rolls; and
- the impact of the County Executive’s Taxpayer Protection Plan.
The Department of Assessment is preparing new statements based on the most up-to-date information possible, including school and general budgets for the 2019-2020 tax year.

Now Available: Notice of Tentative Assessed Value for 2021/2022
Notice of Tentative Assessed Value is an annual statement from the Nassau County Department of Assessment (DOA). It provides every property owner with an updated value of their property. In addition to being posted online here, Nassau County property owners were mailed this notice in January 2020.
If your property assessment increases, it does not necessarily mean your taxes increase. The property value shown in your Notice of Tentative Assessed Value is only one of several factors in determining your property taxes for the 2021/2022 tax year.
Trending Sales Study Percentages
On January 2, 2020, the Department of Assessment published the 2021-2022 Tentative Assessment Roll, providing homeowners with an updated value of their property based on the local real estate market and trends of homes sales in each school district, over the past year. In addition to being posted online, an annual Notice of Tentative Assessment with these updated values were mailed to every homeowner.
Note - If your property assessment increases, it does not necessarily mean your taxes increase. The property value shown in your Notice of Tentative Assessed Value is only one of several factors in determining your property taxes for the 2021-2022 tax year.
A majority of Tax Class 1 2020-2021 values were trended up by the factors in a chart you can review in the link below. Properties excluded from the trending were properties that had new construction or substantial alterations, properties that had a tax lot merger or apportionments, and properties with values exceeding $2.3 million in market value. The trends were applied to the 2020-2021 assessed values incorporating any Assessment Review Commission offers made as of December 15, 2019.
Keeping property assessments up-to-date
The County recently completed a reassessment, producing up-to-date market values for every property in the County for the first time in almost a decade to restore fairness and accuracy to the assessment system. The County is continuing to utilize state-of-the-art technology to keep market values current and reflective of the real estate market.
Good news! Property value in Nassau County is increasing
Our assessments reflect the real estate market which shows that home values are generally increasing, which is a great thing for Nassau County’s homeowners. Increased home values validate home investments here in Nassau County. It means that homes are worth more than they were the year prior.

If you disagree with the updated market value of your property in your Notice of Tentative Assessed Value, you can file a grievance with the Assessment Review Commission (ARC).
