Nassau County 2026/27 School Tax Bills Are Out

4 Things Property Owners Should Check

Nassau County's 2026/27 school tax bills are now available, and many homeowners are taking their first look at what they will be paying this year. If your bill is higher than expected, don't look only at the total amount due. There are several things worth checking.

1. Check Your Assessed Value

Your property taxes are based in part on the assessed value assigned to your property. Even if your assessment did not increase, your tax bill can still change because tax rates and other factors change from year to year. If your property's assessment appears high compared with its actual market value, it may be worth having the assessment reviewed.

2. Confirm Any Prior Reduction Was Applied

If you previously filed a Nassau County property tax grievance and received a reduction applicable to the 2026/27 tax year, review the assessment shown on the bill and make sure the expected reduction is reflected. A successful grievance can result in a lower tax bill, a corrected bill, a credit or, depending upon timing, a refund.

3. Review Your Exemptions

Check whether exemptions that previously applied to the property are still reflected on the bill. STAR and other available exemptions are separate from the property tax grievance process, but they can have a significant effect on the amount ultimately due.

4. Don't Wait Until Next Year's Bill to Review Your Assessment

A common mistake is waiting until a tax bill arrives before thinking about whether the underlying assessment is too high. Nassau County property tax grievances are filed well before the tax bills based upon those assessments are issued. Reviewing your property early gives you time to determine whether the next assessment should be challenged.
