re: Special Session: Black Caucus issues an ultimatum to increase income tax

Never mind the fact that the federal tax cuts in 2018 will result in higher state income tax receipts by itself.

Lowering the federal income tax means you'll take a lower income tax deduction on presumably the same or higher AGI, resulting in higher taxable income for the state. A married couple with AGI of $120k will already pay nearly $200 more in state taxes in 2018 than they did in 2017, assuming no changes to state tax brackets.
