January 2 Is Grievance Filing Day: Why Nassau Homeowners Should File for the 2027–28 Tax Year

Introduction
January 2 marks the official start of the grievance filing period with Nassau County’s Assessment Review Commission (ARC) for the 2027–28 tax year.
This is the first day homeowners can submit applications—and one of the most important opportunities to take action against over-assessment.
What Is the Assessment Review Commission (ARC)?
The ARC is responsible for reviewing property tax grievance applications in Nassau County. Filing allows homeowners to request a review of their property’s assessed value for future tax years.
According to P.T.R.C., Inc.’s FAQ, filing a grievance does not affect your current tax bill and carries no penalty if no reduction is granted.
Why January 2 Matters
P.T.R.C., Inc. Deadlines page highlights that Nassau County allows grievance filings once per year only. Missing the deadline means waiting another year to challenge your assessment.
Filing early helps ensure:
- Proper documentation
- Accurate valuation comparisons
- No last-minute filing issues
Who Should Consider Filing
You may be eligible if:
- Your assessment is higher than similar nearby homes
- You purchased your home for less than its assessed value
- Your taxes increased despite little market change
P.T.R.C., Inc. regularly finds that many homeowners qualify without realizing it.
How the Filing Process Works
As outlined on P.T.R.C., Inc. How to Apply page, the process is simple for homeowners:
- P.T.R.C., Inc. reviews your property and assessment
- Required forms are prepared and filed on your behalf
- P.T.R.C., Inc. manages all communication with ARC
- You pay only if a reduction is achieved
Homeowners do not need to attend hearings or deal directly with the county.
