When your 2026-27 school tax bill arrives
| County | Bill mailed | First half due | Second half due |
|---|---|---|---|
| Nassau | Late Sept / early Oct 2026 | Nov 10, 2026 (no penalty) | May 10, 2027 |
| Suffolk | Early Dec 2026 | Jan 10, 2027 | May 31, 2027 |
How the May 19 vote shows up on your bill
The school budget vote on May 19, 2026 set each district’s levy — the total dollar amount the district will raise from property tax for the 2026–27 school year. Three things then translate that levy into your specific bill:
- The district’s total taxable assessed value. Sum of every taxable parcel in the district (homes, businesses, vacant land).
- The tax rate. Levy ÷ total assessed value × 1,000, expressed per $1,000 of assessed value.
- Your taxable assessed value. Your parcel’s assessed value minus any exemptions (STAR, Senior, Veteran, etc.).
So even if a district stays under the 2% tax cap, your bill can rise more than 2% if your assessment grew faster than the district average, or you lost an exemption.
Districts that piercing the 2% cap (Shelter Island, Bayport-Blue Point, Uniondale, Lynbrook) needed 60% voter approval to enact higher levies. See the full results page.
Why your bill may be higher than last year
The most common causes, in order of frequency:
- Lost or reduced STAR exemption. Most common single cause. More on STAR delivery →
- Assessment increase. Nassau reassesses every year. If your home’s assessed value rose faster than the district average, your share of the levy grows. Grieve in 2027 →
- Budget piercing the cap. If your district passed a budget over the 2% cap, your levy share rose accordingly.
- New special-district bond. Fire district, library district, or sewer district can add $50–$200/yr in some areas.
- Home improvement added to roll. If you completed a permitted addition or pool last year, the assessor added value this year.
Use the 5-minute diagnostic checklist to identify the exact cause.
How to read your bill line-by-line
Each line of your school tax bill should be:
- Taxable assessed value — your assessment minus exemptions
- Tax rate — your district’s rate per $1,000
- Tax amount — taxable × rate ÷ 1,000
- Exemption credits — STAR exemption (if you have the exemption, not the credit) reduces the school portion directly

What to do if your bill is wrong
Math errors. Errors on the bill itself (wrong rate, missing exemption, transcription) are corrected by your school district’s tax receiver or your town receiver of taxes. Call the number on the bill within 30 days of receipt.
Assessment errors. If you think your assessed value is wrong, you can’t change this year’s bill — but you can grieve for next year:
- Nassau: File with the Assessment Review Commission by March 31, 2027.
- Suffolk: File with your town’s Board of Assessment Review on Grievance Day (third Tuesday of May 2027).
If you miss Grievance Day, see what to do if you missed the Suffolk deadline.
Frequently asked questions
Why did my bill arrive even though I have an escrow account?
Most counties send the homeowner the bill for transparency, even when the lender pays through escrow. Check with your servicer to confirm they received the bill and will pay by the due date.
Can I pay the school tax bill in full instead of in halves?
Yes. Both Nassau and Suffolk accept full payment when the first half is due. No discount for prepayment in either county.
What happens if I miss the first-half deadline?
Penalties begin accruing immediately after the no-penalty grace period (Nov 10 in Nassau, Jan 10 in Suffolk). The penalty schedule increases monthly. See late penalty calculator.
My bill is much higher than my neighbor’s — why?
Most likely cause: different assessed values, or different exemption status. Compare your assessed value to your neighbor’s using the assessment lookup tool for your town. If your assessment is materially higher than comparable homes nearby, grieve next cycle.
When will I know my exact bill for 2026-27?
Nassau homeowners: when the bill mails in late September / early October 2026. Suffolk: when the combined bill mails in early December 2026.
