On the Horizon — Not Yet Law
Massachusetts comprehensive data privacy bill
Still the state most likely to flip to enacted next — it has cleared both chambers unanimously, and only House/Senate reconciliation stands between it and the Governor. The two versions differ enough that the conference has now run past two months.
Status: Senate passed S.2619 40-0 (Sep 25, 2025); House passed its own version, H.5479, 146-0 (Jun 4, 2026); the Senate non-concurred in the House amendment and appointed its conferees Jun 11, 2026, and the House insisted on its amendment and appointed its conferees Jun 17, 2026, seating a six-member conference committee (Sens. Creem, Finegold, O'Connor; Reps. Moran, Farley-Bouvier, Vieira). The committee was still meeting as of a public session on Jul 30, 2026 and has not reported out a reconciled bill. Nothing has reached Gov. Healey's desk. Re-verified against malegislature.gov Sep 11, 2026 — the bill history ends at the Jun 17, 2026 House conference appointment.
Not law yet — no confirmed effective date. Proposed threshold if enacted: 100,000+ consumers.
