About TCA

Tax Correction Agency (TCA) was founded in 1991 by Lance Geller and Peter Norberto to provide professional representation for homeowners seeking real estate tax relief.  Utilizing proprietary computer programs, and in accord with taxpayer rights guaranteed by New York State law, TCA represented over 2,000 Nassau County homeowners in its first year, and won over 97% of its cases.
 
In the decades since then, TCA has filed upwards of half a million residential property tax grievances in jurisdictions across New York.  Today, we work exclusively in Nassau County.
 
We have always done business as Tax Correction Agency; no name change in 33 years.

The Process of Grieving Your Property Tax Assessment in Nassau County

A property tax grievance is the process of challenging your assessed value, also known as your assessment.  This is the number to which many other numbers are applied in the calculation of your property taxes, including your school and general levy bills.  All other things equal, a lower assessed value means you pay less in taxes.
 
Homeowners in Nassau County are notified each January by the Nassau County Assessment Department of their property’s tentative assessed value for the tax year that starts twenty-one (21) months later.  For example, this coming January 2025 Nassau homeowners will receive their Notice of Tentative Assessed Value for 2026/27.  That is the assessment year starting with the first-half school bill in October 2026.
Under New York State law, homeowners have a right to challenge that value, regardless of what it is or how the Assessment Department came up with it.  You can challenge it on your own, or you can challenge it with the help of a representative.
 
TCA is professional property tax grievance representation.  We represent you first to the Nassau County Assessment Review Commission (ARC), the independent body empowered to either offer a lower final assessed value or leave the Assessment Department’s tentative unchanged.  We typically have an ARC result anywhere from 6 to 18 months after filing in January.
 
If ARC fails to make a satisfactory offer, and we have a case we can make at court, we may also represent you at Small Claims Assessment Review (SCAR, i.e. small claims court).  We go to SCAR during the summer, before the start of the tax year in October.
Whether we win at ARC or at SCAR, a successful grievance means you pay less in taxes than you otherwise would, starting with the October first-half school bill, continuing with the second-half school bill and both general levy bills the following calendar year.
 
Because a greivance is won in advance of the start of the assessment year, the savings are layered on top of every other change that occurs from one year to the next.  If you are bound for a $1,000 tax increase, for example, but a grievance saves you $800, you will experience only a $200 increase instead.  Another example: if you are bound for a $100 tax decrease year-over-year, and a grievance saves you $200, then your taxes decline by $300.  Because we bill for savings, and not for change in year-over-year taxes, a successful grievance, it can never cost you more than it saves — it can only save you money.
 
Savings are the difference between taxes owed at the corrected assessed value that we won, and taxes owed at the final assessed value that would have prevailed without the greivance.  You will see the taxes you owe with our work on the property tax bills, and/or on the County Land Records Viewer; but you will never see the taxes you would have owed wihtout the grievance on your bills.  To calculate what you would have owed, we have to recalculate the property tax bills at the assessed value we defeated, which is either your tentative assessed value, adjusted tentative assessed value (if any), or final assessed value (if one was issued before we won a case at SCAR).  We do the math for you before billing, checking to ensure we have calculated savings accurately down to the nearest dollar, but we also provide full, line-by-line calculations upon request.
Our fee is 40% of savings attained at ARC, or 50% of first-year’s savings attained at SCAR.  There is also a $30 court-imposed filing fee – that goes to the court, if and only if we go to court, and may or may not be refunded to you at a later date.  We only bill for first-year’s savings.
 
A lower assessed value can carry forward either in full or in part into future tax years, resulting in savings that pile up for years or even decades.  But we only bill for the first year of savings pursuant to the grievance we did for that year, and nothing more.  There is no auto-renewal or automatic registration, so when you sign up with us you are only with us for one assessment year.
We do however encourage you to sign up with us every year, as there is no downside to you doing so, and substantial upside.  We reach out in the fall to our existing clients, and continue if we do not hear back from them throughout the winter, by mail and email.
 
All we need to get started is a signed authorization form.  You can apply online, download or print a form online, or request a form be mailed, emailed, or faxed.
 
Right now we are filing for the 2026/27 assessment year.  That is the year beginning with your first-half school bill in October 2026, continuing until September 2027.  The ARC filing deadline is currently March 1, 2025.  This deadline is quite firm; if you miss it, you lose the chance to challenge your assessment entirely for that year.
 
Once received, we will process your authorization and send a follow-up letter within a week or so.  Then we will file with ARC before the deadline, receive a determination by no later than March 2026, go to SCAR if necessary by summer 2026, savings (if any) accrue starting with the the first-half school bill in October 2026, and our bill for service (if any) does not come due until early 2027, after you have enjoyed at least half the savings.

Frequently Asked Questions

No. Your assessment can only go down or remain the same.
Nassau County conducted a reassessment, which is being phased in between 2020 and 2025.  This means tax increases for about two thirds of Nassau homeowners.  The 2024/25 assessment year will be Year 5 of this process.
No one from the County or TCA will come to your home.
No. TCA prepares and files all papers and makes all appearances for you.
Exemptions are property tax breaks, typically for people in certain categories such as seniors or veterans.  They are separate from a tax grievance, which challenges the assessed value of the property itself.  A grievance ordinarily has no effect on an exemption, nor vice versa.  We do factor the (rare) exceptions into our billing, so you’re never charged for savings we didn’t win ourselves.
Yes. Real estate values, levels of assessment, tentative assessments, and other factors can change unexpectedly from one year to the next, so many homeowners who reduced their property taxes in the past are still able to win.
Yes, of course.  We will not charge any interest or late fees.

No. The grievance process is almost always completed in advance of the tax year, and takes about two years.

Yes. You have one opportunity to file a grievance every year. Once a tax year’s deadline passes, there is no recourse to file for that year.  Filing a grievance each year ensures that you will not miss an opportunity to lower your taxes.  Waiting for a resolution, which may not come until after the next filing deadline, could cost you in taxes down the line.

Our fee is 40% of savings attained at ARC, or 50% of first-year’s savings attained at SCAR.  There is also a $30 court-imposed filing fee – that goes to the court, if and only if we go to court, and may or may not be refunded to you at a later date.  We only bill for first-year’s savings, even if multi-year savings occur, and we only bill after you have enjoyed at least half the savings on your property tax bills.

About two years.  If you sign up in September 2024, for example, for 2026/27, then savings (if any) do not accrue until October 2026, and our TCA bill for services does not come due until early 2027.

You can visit the County’s Land Records Viewer to see what you owe in school and general levy property taxes.  Note that village taxes are not included on the County’s website, nor Glen Cove school taxes.

No one knows!  Call the government, ask that question, and they will give you the same answer.  It’s not knowable.  What is certain is that if you can get your assessed value reduced from the tentative value the Assessor determines in advance, then you will pay less than you would otherwise be destined to pay.

Some people in the media and government use the term “freezing” to refer to the act of copying a tentative assessed value from some other assessed value (final or tentative) from some prior assessment year.  It doesn’t mean that your taxes will remain the same, it doesn’t mean you can’t grieve your assessment, etc.  They should really say “copy,” not “freeze.”  You can and should challenge that tentative assessment, regardless of where it came from.

Yes. However, homeowners who file for themselves may not get the reduction they deserve. Many are unprepared and do not have the time, experience, data, software, or knowledge to deal with ARC and, if necessary, small claims court. With over three decades of experience, we have the tools, experience, and knowledge needed to negotiate your case to the best possible result, in or out of court.

In general, no.  There are 64 villages in Nassau County, each with its own way of doing things.  That includes different deadlines, norms, processes, paperwork, offices, rolls, data formats, etc.  Each village typically has too few households to be worth the close attention of a tax grievance professional.  Every few years though, when we feel that the village rolls have gotten way out of line with reality, we select a few villages that we think are worth challenging.  For now, though, we aren’t challenging any village assessments.  Of course, we don’t bill for village savings either.

No. If you sign with more than one company, you may delay or even jeopardize your case.  If duplicate representation is not resolved in a timely fashion, the result may cost you hundreds or even thousands in foregone property tax savings.

Many things change from one year to the next, including budgets, federal and state aid, levies, tax rates, exemptions, abatements, number of households, etc.  A grievance can only challenge one variable — the assessed value — and even then, it is challenging a tentative assessed value for a future year that may be different from the final assessed values of prior years.  For example, for 2024/25, your tentative assessed value might be higher than your final assessed value of 2023/24.  Or, you may have an exemption that gains or loses value.  And so on.  Regardless of what other variables change, a reduction from the tentative assessed value to a lower final assessed value, for the same tax year, will always mean you pay less in taxes than you otherwise would, for that year, as assessed value is the base to which all other variables are applied.

We are a small team of dedicated professionals who tend to each and every client individually.  People also tend to call all at the same time — when the authorization period opens up in September, when the tentative assessed values are issued in January, when big tax-related news breaks, when ARC and SCAR decisions come in, when bills go out, etc.  Please make sure to call Monday to Friday, 9 AM to 5 PM, always leave a message if you don’t get a hold of someone, and know that we will always call you back.  You should also feel free to write us any time, at info@TaxCorrectionAgency.org.
