Property Tax & Utility Collection Information

Property Tax Quick Reference 

Your property tax bill is based on your property’s assessed value and the combined town, school, and county tax rates. New Hampshire relies heavily on property taxes to fund local services, as the state does not have a broad income or sales tax. Your bill is calculated by multiplying your assessed value by the tax rate (per $1,000 of value).

Bills can increase if property assessments rise or if local budgets for schools, roads, or public safety require more funding. Rising assessments indicate that your property is appreciating in value, which is a good thing. Current factors driving increases in local government and school budgets include rising healthcare costs, inflation, and reductions in federal and state funding.
