If you earn an income or live in Illinois, you must pay Illinois income taxes. As a traditional W-2 employee, your Illinois taxes will be withheld and deposited from each paycheck automatically. You will see this on your paycheck, near or next to the federal taxes.

If you work remotely, you should pay taxes to the state in which the work is performed. Employers will generally also pay taxes on wages paid to these workers to the same state, even if the employer has no physical presence in that state. However, some states may require that workers are taxed based on their employer’s location.

Deducting Illinois income taxes

If you pay Illinois income tax, the IRS allows you to claim a deduction on your federal tax return for them. You can claim a state income tax deduction if you itemize deductions on your federal return.

To determine if you should itemize your deductions, add up your calendar-year deductible expenses, including your state income tax expense, to see if the total is greater than the standard deduction amount for your filing status. If you are single you can claim a standard deduction of $12,200. So, if you pay more than $12,200 in state income taxes and other itemized deductions, then consider itemizing your taxes.

Due to the Tax Cuts and Jobs Act, state and local tax deductions, including state income taxes, are limited to $10,000 per year.
