Thank You!

See you in September!

Thanks for opting in!  We will send you an authorization form in September 2024, to grieve your property tax assessment for the 2026/27 tax year.  Please rest assured that we will only use this opt-in form for that purpose, and no other.

We do not, and will not, share your information with any third party, nor use it for any purpose other than sending you a form for 2025/26.  You may remove yourself from our mailing list at any time by sending an unsubscribe request to

While you wait, please feel free to browse our frequently asked questions:

No. By law, the assessor cannot raise your assessment because you filed a grievance. 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.  They came up with brand new assessed values from scratch.  Our review of the rolls and the housing market suggest that the reassessment numbers are far from perfect, and well worth challenging, each and every year, especially during this five-year phase-in period.
No one from the assessor’s office or TCA will come to your home.
No. TCA prepares and files all papers and makes all appearances for you.
Exemptions are tax breaks for people in certain categories, such as seniors or veterans.  They are separate from a tax grievance, which challenges the assessed value of the home.  Typically a grievance has no effect on exemptions, nor vice versa.  In the rare exceptions, we do factor that into our billing, so you’re never charged for savings we didn’t win.  You can and should apply for exemptions on your own.
Yes. Because real estate values, levels of assessment, tentative assessments, and other factors can change unexpectedly from one year to the next, many homeowners who reduced their property taxes in the past are still able to win.
Yes, of course.  And no, we will not charge any interest or late fees.

No. The grievance process takes a long time – about two years – and is all done in advance of the tax year.

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 due to a missed deadline.

In Nassau County, the tax grievance process generally takes about two years from beginning to end.  We begin accepting authorizations in the fall, then file with ARC in the winter and spring, negotiate with ARC by the next fall or winter, go to court if necessary the following summer, before the assessment we’ve (hopefully) won takes effect in the fall.  The process is long, is all done in advance, and every year we are dealing with multiple tax years from the past, present, and future.

You can visit the County’s Land Records Viewer to see what you owe in your school and general levy property taxes.  Note that village taxes are not included on the County’s website.

No one knows!  Call your Receiver of Taxes, ask that question, and you will get 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.

Unfortunately, the term “freezing” is very misleading.  Each year, the Assessor’s Office issues a tentative assessed value for every home, which takes effect about two years later.  “Freezing” means that the tentative assessed values are “copied” from some prior year’s numbers.  It’s what happens when the Assessor does not actively adjust tentative assessments up or down compared to some prior year.  It does NOT mean that you can’t or shouldn’t challenge that tentative assessment.  It also doesn’t mean your taxes will stay the same: many things change from one year to the next, including budgets, federal and state aid, levies, tax rate, exemptions, abatements, number of households, etc.  “Freezing” has zero effect on anything but the tentative assessed values — and even then, again, they are not “frozen” so much as “copied” from one year to the next.

Yes. However, homeowners who file for themselves may not get the reduction they deserve. Many are unprepared and don’t have the time, experience, data, or knowledge to deal with bureaucrats and courts. We have 30 years of experience, and all the tools we need, to negotiate your case to the best result possible.

In general, no.  There are 64 villages in Nassau, 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 2023-24, though, we aren’t challenging any village assessments.  Of course, we don’t bill for any village savings either.

No. If you sign with more than one company, you will delay your case.  You might even end up with no grievance at all, if duplicate representation is not resolved in a timely fashion.

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 assessed values of prior years.  For example, for 2024/25, your tentative assessed value might be higher than your tentative or final assessed values from 2022/23 or 2023/24.  Or, you may have an exemption that gains or loses value.  Etc.  Regardless of what other variables change, however, a reduction in one year’s assessed value will always mean you pay less in taxes than you otherwise would, for that same year, as it 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
