Illinois lottery tax FAQ
How much tax does Illinois take from lottery winnings?
Illinois withholds its flat 4.95% income tax on prizes over $1,000.
What would I actually take home from a $500 million jackpot in Illinois?
Taking the lump sum (cash value about 47% of the jackpot), you would clear roughly $136,461,543 after federal and state taxes. Taking the 30-year annuity, the after-tax total is roughly $291,571,282, paid in 30 growing installments.
Is the federal tax the same in Illinois as everywhere else?
Yes. Federal treatment is identical nationwide: 24% is withheld on prizes over $5,000, and jackpot-size winnings reach the 37% top bracket (income above $640,600 for a single filer in 2026), so the remainder is due when you file.
Do I pay Illinois tax if I bought the ticket somewhere else?
State withholding follows the state of purchase. If you live in Illinois but bought the winning ticket in another state, that state withholds first — Illinois then taxes you as a resident with a credit for tax paid there (rules vary; confirm with a tax professional).
