Owners of an average single-family home in Dartmouth will pay roughly $3,615.63 in property taxes beginning next year.

The new rates come following the Select Board’s unanimous approval at a Dec. 6 meeting.

Commercial property rates will be an estimated $17.48 per $1,000 of value, down from $17.60 set last year.

Residential tax rates decreased from $9.90 to an estimated $9.40 per $1,000 of assessed valuation. The median home in Dartmouth jumped over 9.4% in value in the past year, going from $343,000 to $378,600 this year.

Assistant Assessor Richard Gonsalves explained that the increase is due to how much larger growth has been in the residential market compared to commercial properties.

“The growth in commercial was only $54,000,” he said. “But yet, in the residential side, it’s six times that.”

To keep residential and commercial tax increases balanced, next year’s percent tax “shift” — a unit that defines how much of the taxes can be shifted onto commercial and industrial properties —  was set to 1.63, the highest “shift” which the board can set under state law.

Gonsalves said nearby municipalities such as Seekonk and Fall River have set lower shifts and that their residents tend to pay higher tax bills.

“In every case I mentioned, it’s cheaper to live in Dartmouth than it is to live in those communities.

Select Board member John Haran stated that he wanted to keep things at its 2021 “shift” of 1.59. He said doing so would “encourage business to come to Dartmouth.”

“We have a lot of empty buildings right now in the Town of Dartmouth,” he said.

Vice Chair David Tatelbaum said while there are many empty commercial spaces around Dartmouth, town officials are currently working to get new businesses to fill those spaces and that he does not think “the rate is going to be of any issue” in attracting them.

“We have so much to offer and it’s such a reasonable rate anyway,” he said. 

Haran ultimately voted in favor of increasing the shift with the rest of the board.
