New Hampshire had one of the 10 highest effective tax rates in the country, according to a study by Attom, a California-based real estate data firm.

Attom reported that New Hampshire’s effective tax rate — calculated using the average annual property tax expressed as a percentage of the average estimated market value of residences in the state — was 1.35 percent, tied with New York state for the seventh-highest in the country. Attom also said that single-family homeowners in New Hampshire paid an average annual tax of $6,698 — the fourth-highest amount in the country, just $79 below Massachusetts.

The five highest 2021 effective property tax rates were found in Illinois (1.86 percent), New Jersey (1.73 percent), Connecticut (1.67 percent), Vermont (1.55 percent) and Pennsylvania (1.37 percent). They were followed by Nebraska (1.36 percent), New Hampshire (1.35 percent), New York (1.35 percent), Texas (1.31 percent) and Iowa (1.31 percent).

Nationally, the average effective tax rate in 2021 was 0.9 percent, the report said.
