Northwest Cook County taxpayers would see a total of $435 million in state income tax increases if a tax hike measure passed by the Democrat-controlled Illinois State Senate becomes law.
The Northwest Cook County community that would see the largest increase is Barrington/South Barrington/West Inverness, which would see a total increase of $55 million and an average increase of $2,650.
Other communities that would see a large collective increase include North Arlington Heights ($27.5 million), West Palatine/East Inverness ($26.4 million), Park Ridge ($25.1 million) and Buffalo Grove ($22.7 million).
Taxpayers from West Palatine/East Inverness ($1,341), Park Ridge ($1,328), Lincolnwood ($1,172) and West Hoffman Estates ($1,093) would see the highest average increases.
Led by Senate President John Cullerton (D-Chicago), Democrats passed the individual income tax hike last week-- from 3.75 percent to 4.95 percent-- along with a broader set of tax increases on businesses.
If their projections prove correct, individual Illinois taxpayers will send an additional $4.453 billion to Springfield each year as a result of the higher rates. Businesses will pay another $1 billon.
LGIS looked at 2014 income taxes paid by zip code to create a ranking of the highest-paying Northwest 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.
