Richard Fromewick Authors, "Nassau County and New York City Real Estate Tax Protests"

Real estate values are continuing to fall in many areas, and certainly for commercial properties it may get even worse. So, when tax assessments are reduced, it's only appropriate. However, many assessments are not reduced nearly enough. The assessments are very uneven with some areas being reduced by 20% and other areas reduced by only 3%-5%. That's why every assessment should be checked. And guaranteed lower assessments will generate higher tax rates. A grievance, also called a complaint, or application to reduce property tax, must be filed by March 1, 2010 to protect your rights to protest your 2011/2012 assessment.
