5 Common Mistakes Long Island Homeowners Make When Filing a Tax Grievance

Filing a property tax grievance on Long Island can lower your annual tax bill - but many homeowners unknowingly make mistakes that hurt their chances of receiving a reduction. With tight deadlines and specific guidelines in both Nassau and Suffolk Counties, even small errors can lead to denied appeals.

Here are the five most common mistakes homeowners make when filing a tax grievance - and how P.T.R.C., Inc. helps you avoid them.

1. Missing the Filing Deadline

The grievance period only opens once per year, and the deadline is strict.
If you miss your county’s filing date, you must wait another year—no exceptions.

P.T.R.C., Inc. files grievances on behalf of thousands of homeowners each year and ensures everything is submitted on time.

2. Believing High Taxes Automatically Mean Overassessment

Many homeowners assume high taxes alone qualify them for a reduction.
But the real issue is whether your property is assessed too high compared to similar homes.

P.T.R.C., Inc. uses market data, recent sales, and assessment analysis to determine whether you’re truly over-assessed before filing.

3. Filing Without Understanding the Assessment Process

Assessment terms like “market value,” “tax rate,” or “equalization rate” can be confusing. Filing without understanding them can lead to mistakes or unrealistic expectations.

P.T.R.C., Inc. explains the process clearly and handles all communication with the county—no guesswork for homeowners.

4. Not Providing Accurate or Complete Property Information

Missing documents, incorrect home details, and incomplete forms are common issues that lead to rejected grievances.

P.T.R.C., Inc. ensures all required information is properly documented and submitted.

5. Trying to Navigate the Appeal Alone

While homeowners can file on their own, many find the process overwhelming.
Missing evidence, unclear comparable sales, or incorrect forms can impact the result.
