How the tax grievance process works
The full sequence, from the tentative assessment roll through ARC’s review and Small Claims Assessment Review.
Walk through the processUnderstand your taxes
Understanding your Nassau County assessment
Make sense of market value, assessed value, and tax bills before comparing your home with nearby properties.
Can filing raise your assessment?
The County states that ARC will never increase an assessment. What that means, and what filing actually costs you.
Property tax exemptions and STAR
How STAR, Enhanced STAR, and other partial exemptions differ from an assessment appeal, and where to apply.
Just bought or built a home in Nassau County?
Why your purchase price and the County’s market value differ, which exemptions you must apply for yourself, and when a new owner can grieve.
Prepare an appeal
The tentative assessment roll: what to check
What to verify on your record when the County publishes its tentative assessment, and how the roll year maps to later tax bills.
Nassau County tax grievance deadline
The published 2027 filing window, a preparation checklist, and where to confirm current instructions.
Choosing comparable sales
Which nearby sales support an appeal, which differences matter, and why a neighbor’s lower bill is not evidence.
How much does a tax grievance cost?
Filing with ARC is free. How representatives charge instead — percentage, flat, or hybrid fees — and what to read before you sign an agreement.
Filing your grievance online with ARC
What to gather before you open the County’s online application, how a filing proceeds in outline, and which confirmation to keep.
After ARC’s decision
Small Claims Assessment Review (SCAR)
Who is eligible, the $30 filing fee, and the short deadline that runs from the roll or from ARC’s decision.
