Traditional tax grievance companies often claim a substantial percentage (40-60%) of your hard-earned tax savings, meaning thousands of dollars could be lost.

While a self-service option exists, it typically leaves homeowners without the crucial data and guidance needed to build a strong case.

Local Property Assessments: Why It's So Confusing & Costly

The Problem

Many tax grievance companies charge an exorbitant 40% to 60% of your tax savings. If you are supposed to save $5,000, they take $3,000-$2,000! That's your hard-earned money handed to someone else.

The Process

Beyond the egregious fees, the property tax grievance process itself is a multi-stage, multi-year ordeal, designed to inherently discourage individual participation and ensure lost savings for unassisted homeowners.

The Solution

The county provides a self-service interface, but leaves you on your own to research and select the precise properties to build a compelling case. LocalTaxCut.com provides the data you need to succeed.

Frequently Asked Questions

1. What is a property tax assessment?

Think of your assessment as the value the county assigns to your home to figure out your fair share of local and school taxes. Each year, Nassau County calculates a "Tentative Assessed Value" for every property.

Important: When you file a grievance, you are challenging this assessment value, not your final tax bill. A lower assessment is the foundation for a lower bill, but the two are not the same thing.

2. I won my grievance, but my tax bill still went up. Why?

This is a frustrating but common situation in Nassau County. It happens because your tax bill is a product of two different factors: Your Assessment and the Tax Rate.

Your Tax Bill = Your Assessed Value × The Tax Rate

While you won a lower assessment (which you control), the Tax Rate (which you don't control) likely increased. This happens for two main reasons:

Bigger Budgets: Your local school district, county, or town increased its annual budget. To collect more money overall, they have to raise the tax rate for everyone.
The Tax Base Shrinks: When many homeowners in your town successfully grieve their assessments (as 70-80% do), the town's total value (the "tax base") shrinks. To collect the same budget from a smaller pool of value, the tax rate must increase for everyone.

Think of it this way: Grieving ensures your slice of the tax pie is as small as possible, but it doesn't stop the size of the entire pie from growing.

3. Why is my "Assessed Value" so much lower than my home's actual market value?

This is a common point of confusion in Nassau County. For several years, official assessed values have not kept up with the rapid rise in real estate prices. This creates a large gap between the value on your tax bill and what your home is actually worth. Because of this, you could still be over-assessed for tax purposes even if your assessed value seems low.

4. Is there a limit on how much my assessment can increase?

Yes. For most residential properties (1-3 family homes), your total assessed value cannot increase by more than 6% in one year or more than 20% over a five-year period.

This cap does not apply to value added by new construction or major renovations.

5. Should I file a tax grievance every year?

Yes, filing every year is strongly recommended.

There is a powerful protection for homeowners: filing a grievance can only lower your assessment or keep it the same—it can never be raised as a result of your filing.

Even if overall tax rates in your town go up, having a lower assessment means you will still pay less than you would have paid with the higher assessment. By not filing when your neighbors do, your "slice of the pie" gets bigger. Filing every year is about controlling what you can control and ensuring you are only paying your fair share.

6. How do I file a property tax grievance?

The process is straightforward and can be done online without a fee.

Know the Deadline: The next official filing period for the 2027/2028 assessment roll is expected to run from January 2, 2026, to March 3, 2026.
File Online: The fastest and most accurate way to file is through the Assessment Review Commission (ARC) website: www.nassaucountyny.gov/arc.
Register & Use Form AR1: You will need to create an account on the ARC website and use Form AR1 for a residential grievance.

7. What evidence do I need to provide?

The strongest evidence is comparable sales—examples of homes similar to yours that recently sold for a price lower than your home's effective market value.

For homeowners with the time for in-depth market research, a do-it-yourself approach can be beneficial. However, given that homeowners get only one shot at filing their grievance each year within a very short window, building the strongest case possible is crucial. LocalTaxCut.com empowers many others by providing a deeper insight into recent home sales, assessment values, and exclusive local market data, ensuring they have the most competitive information available.

Whether you use our service or do it yourself, the goal is the same: to show that the average sale price of comparable homes is lower than your property's effective market value, which demonstrates that you are over-assessed relative to your neighbors.

8. Do I need to hire a lawyer or tax grievance company?

No, you are not required to hire a representative. Before you decide, it's vital to understand the difference between filing yourself and hiring a firm.

Hiring a Grievance Firm:

Most firms charge a "contingency fee," typically 40% to 60% of the first year's tax savings. However, there is a critical detail you must understand:

Critical: Fees are Based on Gross Reduction, Not Your Net Savings.

The firm's fee is calculated based on the total assessment reduction they achieve for you. You owe this fee even if your overall tax bill goes up due to rising school tax rates. For example, if a firm secures a reduction that equates to a $2,000 savings on paper, and their fee is 50%, you owe them a $1,000 lump-sum payment, regardless of whether you actually see that $2,000 savings in your wallet. Many homeowners find this "self-defeating."

The DIY Option with LocalTaxCut.com:

You Keep 100% of Your Savings: The county does not charge a fee to file an appeal. When you use our service to get the best evidence and file yourself, we charge you a flat fee of $85 + sales tax for competitive information, and you keep every dollar of your savings.
It's Quick and Easy: The online filing process with the county is straightforward and typically takes only about 10 minutes to complete once you have the right data from us.

9. What happens after I file?

Confirmation: You'll receive an email confirmation and a receipt number.
Review: The ARC's appraisers will review your application. This can take up to 15 months.
Decision: The ARC will either leave your assessment as is or offer a reduction.
Appeal (If Necessary): If you are not satisfied, you can appeal further through the Small Claims Assessment Review (SCAR), a low-cost process designed for homeowners.
