An Act to manage federal tax changes in Massachusetts

This bill (H 4975) updates Massachusetts tax law to align with federal tax changes while protecting state revenue. Key provisions include increasing the personal exemption from $1,200 to $2,000 (adjusted for inflation), adding a federal deduction for certain taxpayers, and creating a new 4% excise tax on pass-through entities (like S-corps and partnerships) for income exceeding a surtax threshold (Chapter 63E). It also establishes a rule (Section 5) preventing Massachusetts from applying federal tax changes that would impact state revenue by less than $20 million, unless the tax commissioner approves. The bill directly affects individual taxpayers, businesses structured as pass-through entities, and state tax administration.
