The Maine House of Representatives has rejected Gov. Paul LePage's effort to abolish the income tax.
The Democratic-controlled House voted 82-64 against the Republican governor's proposal on Monday.
LePage wants to amend the constitution to prohibit the state from collecting the income tax beginning in 2020. Constitutional amendments need two-thirds support in both chambers to pass and must be approved by voters.
Analysts have estimated that doing away with the income tax would cost the state $1.7 billion a year.
Democrats say that such a move would force massive cuts to education and social programs. But Republicans say that voters should get to have a say on the issue.
The measure now heads to the Senate, which is controlled by Republicans.
