A senator from South Boston delayed action Monday on a controversial, time-sensitive Boston property tax reclassification bill, which is now on ice until after the deadline for action recommended by Boston Mayor Michelle Wu.

Boston Mayor Michelle Wu’s controversial plan to raise commercial tax rates hit another snag on Beacon Hill Monday, when it was blocked by a member of the Senate, with the City Council’s annual tax-rate-setting hearing bearing down the next day.

Sen. Nick Collins of South Boston used a procedural maneuver to delay a vote on the controversial and time-sensitive Boston property tax bill until the Senate meets again on Thursday. Boston Mayor Michelle Wu says the bill is necessary to prevent a major price hike for residential taxpayers.

The Massachusetts Senate tabled a vote on Mayor Michelle Wu’s property-tax proposal until Thursday, which Wu has said would be too late to put altered tax rates into effect.

In a rare second appearance before state lawmakers, Boston Mayor Michelle Wu Wednesday made another push for the authority to temporarily shift more of Boston’s property tax levy onto commercial and industrial property owners.
