(Note there is an example near bottom)
In most towns, villages and cities you must file your challenge/grievance in writing we suggest you file it a few weeks before these deadlines.
Check with your assessor to confirm Grievance Day in your community
Grievance Day is the deadline for submitting Form RP-524 and the day that the Board of Assessment Review (BAR) meets to hear complaints. In most communities, Grievance Day is the fourth Tuesday in May. However, there are exceptions:
If you are dissatisfied with the decision of on your tax assessment grievance by your municipality, you may appeal your assessment again via:
Step 1) Your home is currently worth $450,000 (check with an appraiser etc to confirm)
Step 2) You are assessed at $370,000 according to your tax bill or other town records.
Step 3) Say you live in the Suffolk county, Town of Brookhaven You go to this link http://orps1.orpts.ny.gov/cfapps/MuniPro/ Select your county Suffolk ; then select your town Brookhaven; then select “RAR Information” take the most current RAR from the table for the year 2019 Brookhaven has an RAR of 0.79 or 79 percent
Step 4) Take RAR and multiply it by the appraised value of your home $400,000 * 0.79 = $316,000
This should give you the current home property tax assessment of your home plus or minus 5 percent if correctly assessed; 316,000/370,000 = about 0.85 or 8.5 percent, so it is NOT within 5 percent.
Also amount we got $316,000 is LOWER than example home current tax assessment of $370,000 so our example is over assessed.
Step 5) Then the homeowner would take copy of the appraisal or other document proving the full market value of the home; and attach it to the form you prepare and file the tax grievance via the link below which must be received before the deadline date which varies by municipality from mid-February to June every year See fifth step above for deadline details. Our example would ask for a new assessment of $316,000 https://www.tax.ny.gov/pdf/publications/orpts/grievancebooklet.pdf
If the RAR for your municipality is greater than one (1) that means your whole town/city/village is over assessed at more than 100 percent full market value which is unlawful in NY. However, the only method available to force a municipality to obey the law and reduce everyone’s assessment down to full market value is a lawsuit in New York State Supreme Court. (a trial court in NY).
This means the court should order all residential assessment in the municipality reduced by multiplying the each assessment by the reciprocal of the RAR (1/RAR) to return the municipality to full value assessment.

The RAR should NOT be used for agricultural, industrial, or commercial property assessment
