“Striving for fairness and accuracy, the Department of Assessment has completed the challenging reassessment process and produced updated market values for every property in Nassau County,” said County Executive Laura Curran. “This was a tremendous effort by the hard-working employees at the Department of Assessment and by our two vendors Standard Valuation Services and Michael Haberman Associates. I congratulate County Assessor David Moog and his team for an outstanding job.”

Notice of Tentative Assessed Value

In addition to being posted online, Nassau County property owners will receive in the mail by January 31, 2019, a Notice of Tentative Assessed Value for the County’s 2020-2021 tentative assessment roll.

• CLASS 1: Residential and Residential Capped

• CLASS 2: Condos, Co-ops and Multiple Dwellings

• CLASS 3: Utility

• CLASS 4: Commercial

Results of Community Feedback:

The updated valuations included in the notices are a result of the Department of Assessment’s 60-day review period, where property owners had the opportunity to review their preliminary new market value, update their property inventory and work with the County’s assessment personnel to identify and account for variables that affect property value. During the 60-day review period, the County’s assessment personnel:

• met with over 13,500 property owners one-on-one at four satellite locations and at the Department of Assessment in Mineola, to explain the reassessment process, address specific concerns and questions, obtain feedback, address questions about exemptions and adjust property inventory;

• counseled 1,167 property owners by email;

• continued to fine tune the data modeling to account for unique factors that influence property value.

As a result of this 60-day review period:

• More than 85,000 values for the 2020-2021 tentative assessment roll were decreased from the preliminary new market values listed in the Assessment Disclosure Notices that were mailed to property owners beginning on November 1, 2018.

• Of these decreases, 20,000 were for vacant land and 65,000 were a result of various adjustment factors including neighborhood, section, block, topography, inventoryadjustments and other taxpayer inputs. For example,systemwide changes were made for properties with brick facades and fireplaces.

• The number of Enhanced Star applications for senior citizens doubled and new senior citizen applications increased by 45%. .

Verification of the Tentative Assessment Roll

County Assessor David Moog will swear an oath verifying the Tentative Assessment Roll on January 2, 2019 at 10:00AM at the Department of Assessment. The posting of the assessment roll begins the challenge period for property owners to grievetheir assessed value and the Notices of Tentative Assessed Value include directions on how to challenge assessments. Curran assures the public that they will always have the right to grieve but they should not have to do so to obtain a correct assessment. It’s the Administration’s job to get it right. The final step of this process will occur in April 2020 when the tentative assessment roll period ends and the County issues the final roll.

“It has been an exciting and fast-paced effort to complete the assessment roll. And it is my privilege to verify it under an oath of office. I will be issuing notices to be posted in offices countywide, alerting the public that the tentative assessment values for the 2020-2021 tax year for every Nassau County property have been finalized and posted online,” said County Assessor, David Moog.

Curran encourages residents with additional questions or in need of further clarification to make an appointment at one of the satellite offices which will remain open until January 31, 2019. Residents can make their appointments at Approximately 1,160 property owners have appointments scheduled for January and more than 7,000 appointment slots are still available.

“During my campaign, I promised to fix the broken assessment system. Despite some expected and unexpected challenges and important adjustments throughout the process, we succeeded. Over the past two months, we listened to all of our property owners’ concerns and appreciated every piece of feedback we received, as it helped our experts generate an accurate assessment roll that we are confident we can defend,” said Curran.
