West Cook County taxpayers will see a total of $230 million in state income tax increases after SB 9, a tax hike measure, passed the Democrat-controlled Illinois State Senate to become law.
The West Cook community that will see the largest increases is Hinsdale, with a $35.9 million total increase and a $4,494 average increase.
Other communities that will see a large collective increase include Burr Ridge ($24.1 million), North Oak Park ($23.1 million), La Grange/Countryside/Indian Head Park/La Grange Highlands ($17.7 million) and Western Springs ($14.7 million).
Taxpayers from River Forest ($2,639), Western Springs ($2,414), Burr Ridge ($1,690) and North Oak Park ($1,560) will see the highest average increases.
Senate Bill 9, a revenue bill that would generate $5.4 billion by raising the income tax rate to 4.95 percent from 3.75 percent and the corporate tax rate to 7 percent from 5.25 percent, passed 36-18 on Tuesday. It passed the House on Sunday. Gov. Bruce Rauner then vetoed the bill, but the Senate quickly overrode his veto. The House is expected to vote on an override Thursday.
LGIS looked at 2014 income taxes paid by zip code to create a ranking of the highest-paying West Cook County communities.
Its analysis looked at the percentage of total state income taxes paid by zip code, as reported by the Illinois Department of Revenue. It then applied that percentage to the amount Senate Democrats expect their tax hike will raise to calculate an average increase.
The analysis used 2014 tax return data, which is the latest available and also represents a year in which state income taxes were higher-- five percent, or approximately the level to which the Democrats are hoping to raise them.
