Lawmakers are moving Monday to begin negotiations on a mid-year spending bill that could steer more money toward home care services, rental aid, hospital funding, and more.

An aide in the House’s budget-writing committee said legislative leaders planned during Monday’s sessions to convene a six-person negotiating committee that would iron out a fiscal 2025 supplemental budget whose loose ends have dangled over Beacon Hill for weeks.

The House on May 21 approved a $537 million proposal to replenish appropriations for elder home care services, homelessness prevention, child care assistance, and more, and to authorize funding for collective bargaining agreements.

A bit more than a week later, the House and Senate agreed to splice out — and Gov. Maura Healey quickly signed — a $190 million infusion for child care services. Then, on June 18, the Senate advanced the remnants of the original proposal with added money for fiscally strained hospitals and community health centers.

Nearly a month elapsed without additional action to resolve the underlying portions of the bill that had cleared both branches in different forms.

The House Ways and Means Committee began polling its members Monday on the original House bill. A committee spokesperson called that “a procedural move” necessary to commence conference committee — a group of six lawmakers tasked with building a compromise bill — discussions that could produce a final accord.

“The House will need to re-engross [the bill],” committee spokesperson Blake Webber said Monday morning. “That will happen in session later today. Then the Senate will have to appoint conferees and send back to the House for us to do the same. The hope is that all that happens today.”

Both branches were scheduled to meet in informal sessions at 11 a.m.

The House has a formal session planned for Wednesday, and top Democrats have not yet revealed what they plan to bring forward for votes.
