Illinois is one of only three states in the nation that completely exempts ALL retirement income from state income tax — joining Mississippi and Pennsylvania. In Illinois, your 401(k) withdrawals, IRA distributions, pension income (including state and federal government pensions), military retirement pay, and Social Security benefits are all 100% exempt from the 4.95% state income tax. This is a massive advantage for retirees: a couple drawing $120,000 from a pension and 401(k) saves approximately $5,940 per year in state income taxes compared to states like Wisconsin (which taxes most retirement income). However, other income during retirement — such as rental income, consulting income, or investment income above certain types — remains taxable at 4.95%.

Insight

Illinois is one of the most retirement-friendly states for income tax: ALL retirement income is fully exempt — 401(k) and IRA withdrawals ($50,000), Social Security ($24,000), and pensions ($30,000) are $0 in IL state tax. Only non-retirement income (like part-time earnings or rental income: $10,000) is taxed at the flat 4.95% rate. Compare this to California (taxes almost all retirement at up to 13.3%) or New York (only $20K pension exclusion). The primary drawback for IL retirees is the high property tax, not income tax.

Frequently Asked Questions

Does Illinois tax 401(k) and IRA withdrawals?

No. Illinois completely exempts all traditional 401(k) and IRA withdrawals from state income tax. This is a major benefit compared to most states that tax these distributions as ordinary income. A retiree withdrawing $60,000 from a 401(k) saves $2,970 per year in Illinois state taxes.

Does Illinois tax pension income?

No. All pension income is fully exempt in Illinois — including private pensions, state government pensions (SERS, TRS), federal government pensions, and military retirement pay. Illinois exempts pensions even though it has a pension funding crisis — retirees benefit from the exemption that was constitutionally protected.

Does Illinois tax Social Security benefits?

No. Illinois fully exempts Social Security benefits from state income tax. Combined with the exemption on pensions and 401(k) withdrawals, most retirees in Illinois pay zero state income tax on their primary income sources.

What retirement income IS taxed in Illinois?

While qualified retirement income is exempt, non-retirement income during retirement is taxable at 4.95%. This includes rental income, consulting or freelance income, income from investments (dividends, capital gains, interest), and wages from part-time work. Only income from 'retirement systems, pension plans, and retirement annuities' qualifies for exemption.

Is Illinois a good state to retire in despite high property taxes?

For retirees with substantial 401(k)/pension income and low property, Illinois's income tax exemption is powerful — a couple with $100,000 in retirement income saves roughly $4,950/year in state taxes vs a state that taxes retirement income. However, high property taxes ($5,000-$8,000/year on a $250K home) offset this benefit. Seniors should also check IL's Senior Freeze and Senior Assessment Freeze exemptions.

Important Information for Illinois Residents
