Attention Homeowners: Notice of Tentative Assessed Value for 2021/2022 Now Available

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. The property value shown in this notice is one factor in determining your property taxes for the 2021/2022 tax year. In addition to being posted online here Nassau County property owners will receive this notice in the mail by January 31, 2020. The notice also contains each property’s market value and the level of assessment used to calculate the tentative assessed value, along with helpful explanations of these terms.

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.

County Executive Laura Curran’s Taxpayer Protection Plan

Taxpayer Protection Plan statements that show hypothetical estimated property taxes for the 2020-2021 tax year are available online at MyNassauProperty.com. Also, an updated Frequently Asked Questions page on AsktheCountyAssessor.com provides more information on the plan.

The plan will secure exemptions for class one residential property owners experiencing assessment increases that will effectively spread out any relative changes, increases and decreases, in tax burden due to the reassessment, over a five-year period.

The TPP will be effective for your 2020-2021 school and general tax bills. You will see the effects of the TPP in your school tax bill in October 2020 and your general tax bill in January 2021.”
