Winnebago County residents will pay an additional $68.98 million 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 Winnebago County communities will pay the most: Rockford ($9,939,441 total/$720 per person), Roscoe ($7,415,760/$809), Loves Park ($5,821,735/$686) and Machesney Park ($5,009,898/$479).

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 when paid twice a month. 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.
