How Your Illinois Paycheck Works

The Land of Lincoln, where towering skyscrapers, bustling city streets, and miles of rolling farmland coexist in harmony. From the shores of Lake Michigan to the rolling hills of Shawnee National Forest, Illinois is a state full of charm, diversity, and history.

The state also boasts a diverse economy, with thriving industries ranging from agriculture to finance to technology. At the heart of this economy is the wage system, where workers earn their livelihood through regular paychecks. Yes, those little pieces of paper or electronic transactions that arrive every week or month, filling our pockets with the hard-earned fruits of our labor. Whether you work in Chicago, Rockford, or somewhere else, let's take a look at how getting paid works here.

When you start a job in the Prarie State, you need to fill out a W-4 form for federal withholding and an IL-W-4 form for state withholding. Your employer will then withhold federal and state taxes from your gross pay based on these forms and other factors such as deductions and exemptions.

Your take-home pay will be lower than your gross pay because of these taxes. This is the amount that actually goes into your bank account or paycheck every pay period. You can use this amount to help estimate your budget and spending.

Illinois has a flat income tax of 4.95%, which means everyone’s income in Illinois is taxed at the same rate by the state. This is different from many other states that have progressive income tax systems, where higher earners pay higher rates.

As far as local income taxes, there aren't any, so as far as taxes go, you only have to worry about federal and state ones on your income.

The federal government taxes your income based on your filing status, taxable income, etc. In contrast to state tax, federal income tax is progressive and your income is split into multiple brackets where lower brackets are taxed at lower rates and higher brackets are taxed at higher rates.

In addition to federal and state income taxes, you will also pay FICA taxes for Social Security and Medicare. These are federal payroll taxes that fund these programs for retirees and disabled people. The Social Security tax rate is 6.2% and the Medicare tax rate is 1.45% for both employers and employees. Those earning high incomes may see an additional 0.9% Medicare surtax. Note that social security is only applicable on income up to up to $147,000 in 2022.

You may also have other items taken from your paycheck, such as health insurance premiums, retirement contributions, or garnishments. These items may be pre-tax or post-tax depending on their nature and your preferences.

One thing that is unique about Illinois is that it has a reciprocity agreement with some neighboring states: Iowa, Kentucky, Michigan, and Wisconsin.

This means that if you live in one of these states but work in Illinois, you do not have to pay Illinois state income tax on your wages earned in Illinois. Instead, you will pay state income tax to your home state only. This allows non-residents to avoid paying double taxes on their wages.

If this applies to you, you should be aware of Form IL-W-5-NR. You can file this form with your employer to request that no Illinois tax be withheld from your paycheck.

However, if you had Illinois tax withheld by mistake when it shouldn’t have been, don't worry, you can claim a refund by filing an Illinois tax return (Form IL-1040) and including Schedule NR for your nonresident status.

Looking towards the future, the income tax situation in Illinois may change due to past efforts of a proposed constitutional amendment that would replace the flat tax with a graduated tax system that would charge higher rates for higher incomes. This amendment was on the ballot in November 2020 but failed to pass by a narrow margin. However, some lawmakers and advocates are still pushing for this change as a way to address the state’s fiscal problems and make the tax system more fair and progressive.

When it comes time to file your taxes, you'll see that a state standard deduction exists in the form of a personal exemption and varies based on your filing status and income. High income earners earning over certain limits do not qualify for the personal exemption deduction though.
