About Property Taxes in New Hampshire
New Hampshire relies more heavily on property taxes than almost any other state. With no income tax or sales tax, property taxes are the primary funding mechanism for local government and public schools. Property is assessed at full market value (100%) and administered entirely at the town and city level. Tax rates (expressed as dollars per $1,000 of assessed value) vary significantly by municipality and can range from around $10 to over $35 per $1,000 depending on local spending and state education tax allocations. The state also levies a statewide education property tax that appears on all property tax bills.
Payment & Assessment
New Hampshire property tax payment schedules vary by municipality, but most towns bill semi-annually: First bill: Due in July or August (based on the prior year's rate as a preliminary estimate) Second bill: Due in December (final bill based on current year's rate) Some towns bill quarterly or annually. Interest of 8% per year applies to overdue taxes. Most towns offer online payment or accept payment by mail and in person at the town hall. Contact your local tax collector for specifics.
