Wages and Salaries: Earnings from employment or self-employment.
Capital Gains: Profits from the sale of assets like stocks or property.
Interest and Dividends: Earnings from investments.
Retirement Income: Certain types of retirement benefits, although Illinois does exempt pension income from state taxes.

Standard Exemption: Illinois provides a personal exemption that you can subtract from your taxable income, effectively lowering your tax bill.
Tax Credits: These can include credits for property tax, education expenses, and earned income, which directly reduce your tax liability.

Attempts at Tax Reform

Graduated Income Tax Proposal: Talks around shifting from a flat tax to a graduated rate have been ongoing but were rejected in recent referendums. Such changes would significantly alter how different income groups are taxed.
