Illinois Powerball Tax Calculator: How Much Would You Keep?
Estimate an Illinois Powerball cash payout after federal and Illinois income taxes. See the 24% federal withholding and 4.95% Illinois withholding separately from the estimated final tax bill.
Illinois Uses the Same 4.95% Rate for Lottery Withholding and Individual Income Tax
Illinois has a flat 4.95% individual income-tax rate. The Illinois Lottery also withholds Illinois tax at 4.95% on qualifying prizes, which makes the state side of a large same-state Powerball estimate much simpler than a progressive-tax state.
Illinois withholding
Illinois requires state withholding from Illinois Lottery payments of $1,000 or more, and the current state rate is 4.95%.
Flat state rate
The current Illinois individual income-tax rate is also 4.95%, rather than a graduated bracket system.
Federal gap still matters
The federal withholding is 24%, but a giant jackpot can create a much larger final federal bill under the 2026 progressive brackets.
Illinois withholding can be close to the modeled final Illinois tax on the prize. The calculator still keeps the two figures separate because a real Illinois return can include exemptions, credits and other adjustments.
Illinois Powerball Cash Payout & Tax Calculator
The winning-ticket state is fixed to Illinois. Use the current stored Powerball jackpot and cash option or enter your own amounts. The calculator estimates federal tax and the Illinois tax attributable to the cash payout.

Estimated share of the cash option remaining after modeled federal and Illinois tax.
Illinois estimate uses the current 4.95% individual income-tax rate and does not model Illinois exemptions, credits or unusual adjustments. Federal withholding is shown separately and is not deducted twice.
Illinois Powerball Withholding Rates
Illinois requires state withholding from Illinois Lottery winnings of $1,000 or more, for both residents and nonresidents. The Illinois Lottery also withholds federal tax from qualifying large prizes.
| Tax layer | Current rate | Threshold | How the calculator uses it |
|---|---|---|---|
| Federal | 24% | Qualifying large Lottery prizes | Shown separately from estimated final federal liability. |
| Illinois | 4.95% | Illinois Lottery single payment of $1,000 or more | Shown separately from the modeled final Illinois tax. |
Illinois is unusual in a helpful way for this calculator: the published state withholding rate and the current individual income-tax rate are both 4.95%.
Illinois Has a Flat 4.95% Individual Income-Tax Rate
Unlike a state with multiple brackets, Illinois currently taxes individual net income at a flat 4.95% rate. For a very large Powerball prize, that makes the state calculation substantially simpler.
What this calculator includes
- Current Illinois individual income-tax rate of 4.95%.
- Current Illinois Lottery withholding rate of 4.95%.
- 2026 federal brackets and standard deductions.
- Other income entered by the visitor for the federal calculation.
- A clear separation between amount withheld and estimated final liability.
Real Illinois returns can still differ. Personal exemptions, credits, residency and other adjustments can change the final state bill, so the calculator remains an estimate even though the headline Illinois rate is flat.
What If You Buy the Winning Powerball Ticket in Illinois but Live in Another State?
Illinois requires Illinois Lottery withholding from qualifying prizes for both residents and nonresidents. A winner's state of residence can then have its own income-tax and credit rules.
The calculator provides a same-state planning estimate using the current Illinois rate.
The page shows the 4.95% Illinois withholding but does not invent the winner's residence-state tax or credit.
Illinois Powerball Cash Option vs. Annuity
Illinois Lottery describes Powerball jackpots as payable either in 30 annual payments under the annuity option or as a single lump-sum cash payment. Federal and Illinois taxes are withheld from payments.
Cash option
The current live cash value is the starting amount for this page's lump-sum tax estimate.
Annuity
The Illinois Lottery winner handbook describes Powerball jackpot annuities as 30 annual payments.
Tax follows payments
State and federal tax are withheld from annual payments, so an annuity needs a year-by-year model rather than this one-time cash calculation.
