Amherst's town-wide ratio hides a Williamsville premium that lands on non-village homes. Here is the math and the 2026 Grievance Day deadline.
In Amherst, two homes a block apart can pay annual tax bills that differ by thousands of dollars. The school district usually does most of the work. Williamsville district homes carry a higher school tax than Amherst district homes, and homes near the district line can also get caught when nearby village sales pull the assessor's spring numbers upward.
Every spring the Town of Amherst mails a Notice of Tentative Assessment with a new assessed value for each home. That value times the local tax rate becomes the year's bill, and the school district piece is the largest share of that rate. Which school district a home sits in ends up mattering as much as the value the assessor put on it.
If the Williamsville-versus-Amherst math feels like more work than the savings can justify, Fair Appeal handles the full property tax appeal at the Amherst Board of Assessment Review and only charges a percentage of first-year tax savings when the value comes down.
How are Amherst property taxes set in 2026?
The Amherst Assessor publishes a new value for each home every spring, and that value carries into the school, town, and county portions of the year's tax bill. The total tax rate is the combined town, county, and school district share, with the school district piece doing most of the lift. On a typical Amherst home the annual bill lands somewhere between $6,000 and $11,000 depending on assessed value and school district.
The Erie County equalization rate then adjusts how each town's roll compares to current sales for school-aid purposes, and that rate shifts every year. The practical effect for an Amherst homeowner is that two homes assessed at the same number can still pay different bills as the school rate and the equalization rate move year over year.
Why does Williamsville cost more than the rest of Amherst?
Williamsville is its own village inside Amherst, and the Williamsville Central School District also covers Snyder and parts of Eggertsville. The Williamsville school district levies a higher rate than the Amherst school district. Two homes a block apart can pay a four-figure annual gap in school tax on the same assessed value.
There is a second piece. When Williamsville-village homes sell at premium prices, the assessor's spring numbers can pull adjacent non-Williamsville homes upward in step, even when those homes do not compete with Williamsville buyers. That spillover is the part homeowners can usually challenge.
When is the 2026 Amherst Grievance Day deadline?
Amherst Grievance Day for the 2026 tax year is Tuesday, May 26, 2026. The Amherst Board of Assessment Review meets that day at the Northwest Amherst Community Center on Northpointe Road, in two sessions, 1pm to 5pm and 6pm to 8pm. The grievance form must be received by the Board on or before May 26. Postmarks do not count. New York State publishes the full grievance procedure online.
Is an Amherst property tax appeal worth the effort?
For most Amherst homes the question comes down to two checks. Did the spring number go up faster than the local market actually moved, and is the home being valued against Williamsville sales it does not actually share. When both answers are yes, a successful appeal usually saves $700 to $1,000 a year on a typical home, and more on larger ones. The savings repeat every year until the next spring's number moves it.
Most homeowners think about this once and then forget. The school district rate moves every year and the spring values move with it. FairAppeal watches the Amherst tax roll every year, not just once, and only files when the math says it is worth doing. The 2026 Amherst window closes May 26.
