Nassau has completed its first countywide reassessment in nearly a decade, according to Country Executive Laura Curran and Assessor David Moog.

With the stroke of a pen Wednesday, Moog finalized the tentative assessment roll for the 2020-2021 tax year.

"We met with over 13,000 taxpayers...mainly in our satellite offices," Moog says. "From those exchanges with taxpayers, we've actually made changes to over 85,000 parcels."

As News 12 has reported, many Nassau residents have expressed confusion about the reassessment process and frustration over estimated property tax increases.

When Curran announced the changes in the fall, she said taxpayers would have the right to grieve but ideally wouldn't have to because they'd be confident the new assessed values are fair. Yet Republican county lawmakers say that has not happened at all.

Rich Nicolello, the county Legislature's presiding officer, says he expects more than 200,000 Nassau taxpayers to grieve their taxes this year. As a result, the Legislature's Republican majority introduced a bill Wednesday morning that would require the county to extend the challenge deadline from March 1 to April 30.

"I think there's no faith in this process that it was done correctly," Nicolello says. "I think people are confused, I think people don't have the answers that they need."

Jen Biren, of Old Bethpage, says she plans to grieve her taxes, but will have to pay up one way or another.

A spokesperson for Curran questioned whether the Legislature has the legal authority to extend the challenge deadline, but says a "grace period" has generally been allowed with bipartisan support.

The tentative assessed values of properties can currently be viewed online and will be mailed out to residents within the next week.
