What happened: State lawmakers June 9 advanced a constitutional amendment to the November 2022 ballot that will allow Massachusetts voters to decide a 4 percent tax increase on income over $1 million. Only one Republican supported the measure.

Why it matters: If approved, the estimated annual $2 billion in new revenue would be split between education and transportation purposes.

What’s next: Organizations supporting and opposing the “Fair Share Amendment” have already begun the 17-month campaign.
