In a historic vote, the Illinois House on Monday agreed to ask voters to change the 1970 state constitution by authorizing a graduated-rate tax based on the size of income and repealing the currently mandated flat-rate income tax.

The move came on a 73-44 party-line vote, two votes more than the bare minimum needed for approval. It represented a significant victory for first-term Democratic Gov. J.B. Pritzker, who campaigned for election on the concept of taxing wealthier incomes at a higher rate as part of an overall plan to deal with Illinois’ ailing finances.

The proposed amendment won’t go before

Polling indicates the progressive income tax is unpopular in key Illinois House districts.

Comment: Good news for Illinois, in a perverted way. Investors seeking yield are piling into the riskiest corner of the municipal bond market at a pace not seen in decades.
