What you'll pay, at a glance

Property taxes are the largest local tax most homeowners pay. The effective rate measures the real tax bill as a share of home value — a more useful number than the nominal “mill rate,” because assessment practices vary county to county.

How this is calculated

The effective property tax rate is the median real-estate tax bill divided by the median home value — both for owner-occupied homes, from the U.S. Census Bureau's American Community Survey (ACS 5-year estimates)1. Median income is also from the ACS1. Federal and state income-tax figures use IRS2 and Tax Foundation3 data.

About Grand Isle County, VT

Grand Isle County offers Vermont homebuyers a comparatively affordable tax picture despite elevated property values. The median home here costs $394,100, and the resulting annual tax bill comes to about $5,195, based on an effective rate of 1.318%. That rate sits comfortably below Vermont's statewide median of 1.659%, and Grand Isle County actually ranks last among the state's 14 counties for property tax rate — the lowest of them all. Households earning a median of $97,396 can weigh that $5,195 bill against their budget without much strain, especially since per-capita income reaches $56,447. Compared with the national median effective rate of 0.794%, taxes here run higher, but buyers trading a larger metro for communities like Alburgh, Grand Isle, or Isle La Motte gain lower taxes than most of Vermont demands.

Frequently asked questions

What is the property tax rate in Grand Isle County, VT?
The effective rate is 1.32% — meaning the median tax bill equals about 1.32% of the median home value.
How much are property taxes on a median home?
On the median home ($394,100), the estimated annual bill is about $5,195.
Is Grand Isle County's rate high or low?
Compare it to the state median of 1.66% and the national average near 1.1%.
How does the effective rate differ from my mill rate?
A mill rate is the nominal levy per $1,000 of assessed value. The effective rate reflects what you actually pay after exemptions and assessments — it's the median tax bill as a share of median home value, so it better predicts your real cost.
Will a reassessment raise my tax bill?
Not necessarily. If your home's assessed value rises, your bill can go up, but only if the mill rate and exemptions stay flat. Contact the Grand Isle County assessor's office to review your current assessment.
Can I appeal my property tax assessment?
Yes. Most counties allow an appeal when you believe the assessed value exceeds the market value. File with the Grand Isle County assessor within the local deadline, typically with comparable sales as evidence.
