Nassau County Online Property Tax Reduction Service, Syosset, NY (2026)

As a matter of fact, my parents still live in the house I grew up in. I graduated from Franklin & Marshall College with a BA in Business Management and had a successful career in commercial lending for over 20 years. After getting married, I moved to Syosset where I raised my family. As my children grew, I became a full time homemaker but continued to work part time as a travel agent. Property tax

es in Syosset became a major burden and I was advised to approach a grievance company. The problem was they retained 50% of my tax savings as their fee every year. I learned that homeowners were not required to use a grievance company to apply for assessed value reductions. After a thorough online study, I developed a simple way to navigate through Nassau County’s websites. I filed my own application online and received a fair assessed value reduction offer that I felt was in line with my prior period reductions. The following year, I helped my parents apply successfully. For a low fee, I started helping friends file as well. Over time, I began helping owners throughout Nassau County file online so they could retain 100% of their savings. Through recommendations, I am now helping more and more homeowners. Using my procedure, owners are keeping 100% of their tax savings.

Please note that the Assessment Review Commission confirmed on Monday, February 9, that all property owners with a valid (non-duplicate) protest should have received an offer for the 2026/27 tax year.

I provided seven specific parcel numbers to the ARC for homeowners who were being told by other firms that no offers had yet been issued. One firm even stated that “they had received offers on approximately 80% of their cases (as had all the other firms )”. In reality, the ARC confirmed that offers were issued on 100% of eligible cases.

Homeowners should be cautious when hiring firms that guarantee results. No firm can guarantee future grievance savings. I provide each prospective client with a realistic, personalized assessment of their potential outcome.

💼 Not comfortable self-filing? I offer to personally file your grievance for a low, flat rate filing fee (you keep 100% of your future savings!)

The deadline to file 2027/28 property grievances with the Assessment Review Commission ("ARC") was extended today from March 1 to March 31, 2026.

• While tentative values are frozen, your tax bill can still increase. However, your assessed value can be reduced by grieving keeping taxes as low as possible.

• Reductions from the last filing period (except for the 6% cap, if applicable) do not automatically carry over, requiring owners to apply every year.

• Homeowners received 2026/27 reductions last year, even when comparable sales were 30–40% above the tentative market value because the ARC uses a different Level of Assessment than the Department of Assessment, which sets the values.

• Homeowners authorize me to file grievances allowing them to keep 100% of their savings, for a low, fixed fee, rather than paying a percentage to a contingency-based firm.

• My clients appreciate attentive, interactive, and personalized service.

The NOTICE OF TENTATIVE ASSESSED VALUE is for the 2027/28 assessment roll. IT’S SIMPLY A NOTICE AND SHOWS TENTATIVE VALUES REMAIN FROZEN.

This notice is UNRELATED to your 2026/27 property grievance filed last year with the Assessment Review Commission (ARC). The letter does not reflect the outcome of your 2026/27 grievance or any lower accepted settlement offers, if applicable.

2026/27 Final Values:
o The Tax Roll Status will change from "Tentative" to "Final" on the Land Record Lookup website on 4/1/2026.
o Final values will reflect the outcome of last year’s grievance with ARC.
o If you rejected ARC’s final offer, you can file a SCAR (small claims) petition in April 2026.

Tax Calculations:
o The 2026/27 FINAL values will be used to calculate property taxes owed starting with the October 2026 School bill and the January 2027 General bill.
o Property taxes = Taxable Value × Town’s Tax Rate.

Important Notes for 2027/28:
o 2026/27 reduced values do not carry over to the 2027/28 filing period.
o Frozen tentative assessed values do not mean your tax bills are frozen.

Keeping Taxes Low:
o To keep taxes low, apply for a reduction every year.
o After grieving, values will either remain the same or be reduced.
o Reductions are possible even with HIGHER comparable sales than your tentative market value because ARC uses a different Level of Assessment ratio than the Department of Assessment.

Filing Deadline:
o The Level of Assessment ratio is announced after the grievance filing deadline.
o Be sure to file your grievance by March 2, 2026.

🔑 Important Reminder:
