Nassau County, N.Y.
Where Nassau assessments changed most on the 2028 tentative roll
How County market values move from one assessment roll to the next for the same homes, by school district, hamlet, and village.
This comparison needs two assessment rolls, and only the 2028 tentative roll is imported so far. The report appears here once an earlier roll for the same towns has been loaded. Meanwhile, browse the latest figures by area, compare school district taxes, or read what to check on the tentative roll.
What these changes mean, and what they don’t
- A higher value is not automatically a higher tax. Taxes depend on each district’s levy and how it is shared. If every home in a district rose by the same share, each would carry much the same share of the levy as before; what matters is how your change compares with your neighbors’.
- Individual homes move for their own reasons. Renovations, demolitions, corrections, and prior appeals all change a record. A change unlike your area’s is a reason to check your record, not proof of an error.
- The latest roll is tentative. Values can change through corrections and appeals before the roll becomes final, and this page will be refreshed when a newer roll is imported.
- Verify with the County. Check any figure that matters to you in the Nassau County Land Records Viewer. This page summarizes published records; it is not an appraisal.
If your home’s value rose more than similar homes nearby, the tentative roll is the time to look closely. Check your own record and compare it with genuinely similar homes before the filing window closes.
