About New Hampshire property tax

New Hampshire property tax is billed and collected county by county, so the collector — not the state — issues the bill. Municipalities choose annual billing (December 1), semiannual billing (July 1 and December 1) or quarterly billing (July 1, October 1, January 2 and March 31), so coupon dates genuinely differ by town.
