What the effective rate means

The effective rate here is the median tax bill divided by the median home value, which is the standard way to compare property taxes across places. It is not a rate you are billed directly. Your actual bill is your home's assessed value times the local millage rates set by the county, city, school district, and any special districts, minus exemptions you qualify for (such as a homestead exemption). Two homes of the same market value in the same county can owe different amounts.

Property tax is a state and local matter. For the state's income and retirement tax picture, see New Hampshire income tax and New Hampshire retirement taxes.
