Clark County residents will pay an additional $3.82 in state income taxes this year, according to an analysis by Local Government Information Services (LGIS).
LGIS combined Illinois Department of Revenue data with a forecast by Senate Democrats to estimate how much additional income tax will be paid in each Illinois zip code.
The following Clark County communities will pay the most: Marshall ($1.76 million total/$542 per person), Casey ($1 million/$510), Martinsville ($507,578/$476) and Dennison ($195,537/$$656).
Retroactive to July 1, the higher rate -- now 4.95 percent, up from 3.75 percent -- will be withheld from employee paychecks over the last six months of 2017.
Before the hike, someone earning $50,000 paid $72 in state income tax per paycheck. That person will now pay $95, or an additional $600 per year.
Senate Democrats estimate the tax hike will siphon $4.453 billion more this year from individual taxpayers. Businesses will pay another $1 billion.
