Why Most Long Island Homeowners Are Overpaying on Property Taxes

Real estate tax reduction is more accessible than most homeowners realize — and the savings can be significant.

Here are the most common ways to lower your property tax bill:

File a property tax grievance — challenge your assessed value through the Nassau County Assessment Review Commission or your Suffolk County town’s Board of Assessment Review
Apply for the STAR program — available to homeowners earning under $500,000 who live in their own home
Claim a homestead exemption — reduces your property’s taxable assessed value
Apply for senior, veteran, or disability exemptions — income-based reductions of 5–50% or more
Request an assessment cap — limits how much your assessed value can increase each year

The single most powerful tool for Long Island homeowners, though, is the property tax grievance — a formal process to dispute an overassessment directly with your county or town.

Property taxes on Long Island are among the highest in the nation. Many homeowners don’t realize their assessed value may not reflect current market conditions — meaning they’re quietly paying more than their fair share every single year.

I’m Adam Heller, founder of Heller Tax. I’ve spent my career focused on real estate tax reduction for Long Island homeowners, starting with over two decades in real estate before dedicating myself full-time to helping property owners lower their tax burden. In this guide, I’ll walk you through every major option available to you — from state exemption programs to the grievance process in Nassau County and the various Suffolk County towns.

Common Property Tax Relief Programs and Exemptions

When we talk about real estate tax reduction, we usually look at two main avenues: exemptions and grievances. Exemptions are “breaks” given to specific groups of people based on their status or how they use their home. In New York, these property tax exemptions are designed to provide relief to those who might struggle with the high cost of living on Long Island.

To qualify for most of these, the property must be your primary residence. You can’t claim these breaks on a vacation home or a rental property. These exemptions typically apply to “ad valorem” taxes—which is just a fancy way of saying taxes based on the value of your property.

Common homeowner exemptions include:

School Tax Relief (STAR): The most famous New York program.
Senior Citizens: For those age 65 and older with limited income.
Disabled Individuals: For homeowners with physical or mental impairments.
Veterans: For those who served in the military, including specialized breaks for combat zone service.
Clergy: A modest reduction for members of the clergy and their surviving spouses.

While these programs are fantastic, they don’t address whether your home is actually valued correctly by the county. That is where a property tax grievance comes in. Even if you have every exemption under the sun, you could still be overpaying if your base assessment is too high.

Eligibility Requirements for Seniors and Disabled Homeowners

For our neighbors in places like Syosset or Massapequa who are retired or living with disabilities, the tax burden can feel overwhelming. New York offers the Senior Citizen Homeowners’ Exemption (SCHE) and the Disabled Homeowners’ Exemption (DHE).

To qualify, there are usually strict income limits. For example, in many parts of New York, the combined household federal adjusted gross income (AGI) must be no more than $58,399 to see a reduction of 5% to 50% on the assessed value. You’ll need to provide detailed documentation, such as tax returns or Social Security benefit statements, to prove eligibility. If you have questions about how these interact with your specific bill, our FAQs section covers many of the common hurdles homeowners face when applying.

Veteran and First Responder Tax Breaks

We owe a lot to those who serve. If you are a veteran living in Stony Brook or Miller Place, you may be eligible for the Alternative Veterans’ Exemption or the Cold War Veterans’ Exemption. These exemptions often provide a 15% reduction in assessed value for those who served during wartime, with an additional 10% for those who served in a combat zone.

Gold Star parents (parents of a child who died in the line of duty) also qualify in many New York jurisdictions. Furthermore, if you have a service-connected disability, your percentage of disability can lead to an even larger homeowner’s exemption. It’s important to note that surviving spouses typically retain these benefits as long as they do not remarry.

Understanding Real Estate Tax Reduction Through Assessment Caps and Freezes

One of the most confusing parts of the tax bill is the difference between market value and assessed value. Your market value is what your house would sell for today. Your assessed value is the number the county uses to calculate your taxes.

To prevent “tax shock” when property values skyrocket, many areas implement assessment caps. In some jurisdictions, an annual assessment cap might limit the increase of your taxable value to 10% per year, or even as low as 2% for seniors. However, don’t let a cap lull you into a false sense of security. Even with a cap, if your starting assessment was too high, you are still overpaying. This is why all homeowners should file a tax grievance—it is the only way to ensure the “base” number is fair.

How Homestead Deductions Lower Taxable Value

A homestead deduction is a flat amount or percentage subtracted from your home’s assessed value before the tax rate is applied. Think of it like a “standard deduction” on your income taxes, but for your house.

To get this real property tax relief, you must meet domicile requirements, meaning the home is your permanent legal residence. By lowering the taxable value, these deductions provide a direct reduction in property taxes. On Long Island, while we have various exemptions, the heavy lifting of lowering your bill usually requires a more active approach through the grievance process.

State-Specific Programs: From New York STAR to DC Homestead

While every state has its own quirks—like Idaho’s $250 to $1,500 property tax reduction for seniors or the New York real property tax credit for low-income residents—Long Island homeowners should focus primarily on the STAR program.

New York STAR: Exemption vs. Credit

The School Tax Relief (STAR) program is the cornerstone of real estate tax reduction in New York. There are two types: Basic STAR and Enhanced STAR.

Basic STAR: Available for owner-occupied, primary residences where the resident’s income is $500,000 or less.
Enhanced STAR: Provides a much larger benefit for seniors (65+) with incomes usually under $98,700 (though this adjusts annually).

A major change occurred recently: new applicants no longer receive a “reduction” on their bill (the STAR Exemption). Instead, they receive a check in the mail (the STAR Credit). If your income is between $250,000 and $500,000, you must use the credit program. Switching from the exemption to the credit can actually be beneficial because the credit amount is allowed to grow over time, whereas the exemption is frozen. Understanding these tax credit programs is vital, but STAR only addresses the school portion of your tax bill. To lower the rest, you need our complete guide for property tax grievances.

The Strategic Path to Real Estate Tax Reduction: Filing a Grievance

If you live in Nassau or Suffolk County, filing a grievance is the single most effective way to lower your taxes. A grievance isn’t a “complaint” about the tax rate; it’s a legal challenge stating that the county or town has appraised your home for more than it’s worth.

In Nassau County, the process goes through the Assessment Review Commission (ARC). In Suffolk County, the process is handled at the town level through the Board of Assessment Review. If the county or town doesn’t offer a sufficient reduction, we can take the case to a Small Claims Assessment Review (SCAR) hearing.

To win, you need a Comparative Market Analysis (CMA). This compares your home to similar houses in your neighborhood that sold for less than your assessed value. While you can challenge and lower your taxes on your own, the process is paperwork-intensive and requires a deep understanding of local market trends.

Real Estate Tax Reduction Deadlines for 2027

Deadlines are the most important part of the calendar. If you miss the window, you have to wait an entire year to try again.

Nassau County: The deadline to file a grievance for the 2028/2029 tax year is March 1, 2027.
Suffolk County: Most towns in Suffolk (like Brookhaven, Islip, and Smithtown) have a deadline of May 18, 2027.

Because the Nassau County calendar and the Suffolk process operate on different cycles, it’s crucial to know which rules apply to your specific county or town.

You aren’t required to hire a professional, but there are top reasons to hire a professional for your tax grievance. At Heller Tax, we have a 90% success rate in Nassau County. We handle everything: the filing, the market analysis, the negotiations with the county or town, and the court hearings if necessary.

You can read our testimonials and success stories from your neighbors in places like Oceanside and Deer Park who have saved thousands.

How to Apply: Documentation and Deadlines for 2027

Applying for exemptions or a grievance requires a paper trail. You’ll typically need:

Proof of residency: A driver’s license or utility bill.
Income verification: Federal tax returns (Form 1040) or 1099s.
Property info: Your 2026/2027 Reappraisal Notice.

For state-level credits, you might use Form IT-214. For a grievance, you can start with our online tax grievance applications. If you’re curious about how much you could save, check out our Long Island property tax calculator to see the potential impact on your wallet.

Many exemptions like SCHE must be renewed every two years. If you move or sell your home, you must notify the assessor, as these breaks do not automatically transfer to the new owner.

Frequently Asked Questions about Property Tax Relief

Can I combine multiple property tax exemptions?

Yes! You can often “stack” exemptions. For example, you can have a STAR credit, a Veteran’s exemption, and a Senior Citizen exemption all on the same property. However, there are some limitations (for instance, you usually cannot claim both a Veteran’s exemption and a Disabled First Responder exemption in certain jurisdictions).

What happens to my tax reduction if I sell my home?

The exemptions are tied to the owner, not the house. When you sell, the new owner must apply for their own exemptions. However, if you have successfully grieved your taxes, that lower assessment usually stays with the property for the next tax cycle, which can actually be a great selling point for your home!

Does filing a tax grievance ever increase my property taxes?

No. This is the biggest myth in real estate tax reduction. By law, the assessing authority cannot increase your assessment because you filed a grievance. The worst-case scenario is that your assessment stays exactly where it is. You have nothing to lose and everything to gain by appealing your property tax bill.

Conclusion

Navigating real estate tax reduction can feel like a full-time job. Between the income limits for the Philadelphia tax credit program (for our friends out of state) and the complex STAR registration in New York, it’s easy to get lost.
