The Senate 33-5, approved an amendment that would require Massachusetts couples who file income tax returns jointly at the federal level do the same at the state level.

Supporters said this amendment will close a loophole that allows some married couples to file individually – an action that could be used to minimize or avoid the person’s state tax obligations under the newly approved 4 percent surtax which is in addition to the current flat 5 percent one, on taxpayers’ earnings of more than $1 million annually.

Opponents said if filers are forced to file jointly at the state level, the 4 percent surtax will apply to many more filers which is not what the voters approved on the November 2022 ballot question imposing the 4 percent surtax.

(A “Yes” vote is for the amendment requiring joint filing. A “No” vote is against the amendment.)
