The October bill is the first half of the school tax for the 2016/17 tax year. If the assessment was reduced by a tax certiorari complaint in January 2015 complaint, the tax bill in October 2016 should reflect the reduced assessed value. The January 2017 general tax bill should be based on the same reduced assessed value. However, commercial properties will have a much higher tax than normal because of the new Disputed Assessment Fund (DAF). There is little information about this new fund – but guaranteed there will be 10 – 20% higher taxes to create the DAF.It is too late to complain about the assessment on the October 2016 school tax or the January 2017 general tax. The tax certiorari complaint you can file in January 2017 is for the 2018/19 tax year. Sounds complicated and a little wacky – well that’s the New York State mandated assessment procedure for Nassau County.
