Boston City Council President Bill Linehan and City Councilor Frank Baker have proposed a new citywide tax on alcohol sales. The proposal would require the city to use the additional revenue to fund substance abuse programs.

The Boston Globe‘s Sean Murphy reports the proposal would need to be passed by both the City Council and the state legislature. If it is, then a one to two percent tax would be imposed on all alcohol sales in city restaurants, bars, grocery stores and package stores.

Linehan and Baker merely filed paperwork on Monday, meaning the proposal is still in the early stages, the Globe reports. “There is momentum in favor of this,” Linehan told the Globe, referencing the benefits the proposal would have on substance abuse treatment and prevention.

According to the Globe, the tax is expected to provide the city with “millions” in additional revenue, which would be used exclusively for substance abuse programs.

The excise tax on alcohol in Massachusetts is one of the lowest in the country. A 6.25 percent sales tax on booze was repealed by voters in 2010, after the state Legislature passed the measure in 2009.

In February, 2014, Linehan and Baker proposed adding the 6.25 percent sales tax on alcohol sold in Boston package and liquor stores. Linehan said the proposal was dropped after retailers complained the tax was unfair, the Globe reports.

Frank Anzalotti, the executive director of the state Package Stores Association, told the Globe that the group is against the proposed tax. “Alcohol is already taxed. It would mean a tax on a tax,” Anzalotti said.

Mayor Marty Walsh’s office said in a statement that the mayor – who has not shied away from discussing his own alcohol abuse – would review the tax proposal “if it reaches his desk.”

If passed by the City Council, the proposed tax would need to be approved by a majority vote in the House and the Senate and signed by Gov. Charlie Baker.

The City Council is expected to mull over the proposal on Wednesday. Linehan told the Globe, a vote on measure isn’t likely to come for several weeks.
