New Hampshire property tax deadlines

3 sourced dates. 10 of 10 New Hampshire counties have at least one.

In New Hampshire, each town or city bills and collects property tax, usually twice a year, and prints its own due dates on the bill. Counties don't collect it. The abatement deadline depends on the date of your final tax bill, so keep that date handy. After the town decides, you can go to the Board of Tax and Land Appeals or superior court.
