You Can Now View Your New Nassau County Assessment

Nassau County residents can now check the tentative assessments of their home for the 2021-22 tax year. The county updated the assessments of some homes, which will lead to changes in property taxes.

County Executive Laura Curran said that the county used new technology and the most current information to identify the actual market values of homes.

“When our homeowners pay town, school, special district, and county taxes, they deserve assurance that the amounts they are paying are fair and equitable," said Curran. "I am proud to say we are now in our second year of producing more accurate, up-to-date property values utilizing the most current data available and the latest technology. Thanks to the hard work of our assessment team, we’ve made real progress in fixing the prior administration’s corrupted, broken property assessment system.”

Residents can view the tentative assessment of their property by visiting mynassauproperty.com and inputting their address.

If you can't get online to check your assessment, the county will also be sending notices to all residents by Jan. 31. The notice will have your home's market value and the level of assessment that will be used to calculate your taxes.

The posting of the assessments also marks the start of the period to grieve them. If you feel your home has been over- or under-assessed, you can file a grievance with the county. Property owners have until March 2, 2020 to file a grievance.

To help residents understand their assessments, the county has scheduled 19 public meetings in January and February with the Department of Assessment. The schedule of meetings will be sent with homeowners' assessment notifications, and can also be viewed by clicking here. County Assessor David Moog and his staff will be at the meetings to answer questions.
