Illinois Lottery Tax: Withholding, Brackets, and W-2G Reporting

Illinois lottery winnings are taxed twice: the state takes a flat 4.95% as ordinary income, and the federal government taxes the same dollars at your marginal rate, which reaches 37% on large prizes.¹ The Illinois Lottery withholds state tax on any single prize of $1,000 or more and federal tax on prizes over $5,000, but those withholdings often don’t cover what you actually owe when you file.

The Two Layers of Tax on Your Prize

Every dollar you win playing the Illinois Lottery is taxable income on both your state and federal returns. Illinois applies its flat 4.95% individual income tax rate to lottery prizes the same way it treats wages or investment income.¹ There is no reduced rate or exemption for gambling income.

Federal tax works differently. Lottery winnings are ordinary income taxed at your marginal rate, meaning the prize stacks on top of your wages, self-employment income, and everything else you earned that year. A single winning ticket can push you into a bracket you’ve never seen before. For 2026, the top 37% federal rate begins at $640,600 for single filers and $768,700 for married couples filing jointly.² A six-figure prize can put a chunk of your winnings in that top bracket.

Nonresidents get caught by Illinois tax too. If you live in another state and buy a winning ticket here, Illinois still withholds and taxes the prize.³ Your home state may give you a credit for the Illinois tax paid; check its rules before assuming you’ll be made whole.

What Gets Withheld Before You’re Paid

The Illinois Lottery does not hand you the full face value on larger wins. Two separate withholdings come off the top.

State Withholding Starts at $1,000

Illinois law requires 4.95% state withholding on every single lottery payment of $1,000 or more.⁴ The threshold is lower than most winners expect. A $1,200 scratch-off winner loses roughly $59 to state withholding before payment.³

Federal Withholding Starts at $5,000

The IRS requires 24% withholding from lottery prizes over $5,000. On a $100,000 win, $24,000 goes to the IRS at the time of payment. Together with the 4.95% state withholding, roughly 29% of a large prize is gone before you see a check.

Here’s the trap: 24% is only a deposit, not the final federal tax. If the prize lands part of your income in the 32%, 35%, or 37% bracket, you’ll owe the difference the following April.² Winners who spend down the payout without setting money aside sometimes face a five- or six-figure balance due, plus potential underpayment penalties. Making estimated quarterly tax payments in the year of the win is the standard fix.

2026 Federal Brackets: Where Your Prize Actually Lands

Because the flat 24% federal withholding often understates the real tax, it helps to see the 2026 brackets. For single filers:²

10% on taxable income up to $12,400
12% from $12,401 to $50,400
22% from $50,401 to $105,700
24% from $105,701 to $201,775
32% from $201,776 to $256,225
35% from $256,226 to $640,600
37% above $640,600

Married couples filing jointly get wider brackets: the 24% rate begins at $211,400, the 35% rate at $512,450, and the 37% rate at $768,700.² A single filer with $75,000 in wages who wins $500,000 has taxable income near $575,000, putting much of the prize in the 35% bracket. The 24% withheld at claim time leaves a substantial shortfall.

Deducting Gambling Losses Against Winnings

You can deduct gambling losses to offset winnings, but only if you itemize on your federal return rather than take the standard deduction. Starting in 2026, the deduction is capped at 90% of your losses, not the full amount. Win $50,000 and lose $50,000 in the same year, and you can only deduct $45,000, leaving $5,000 of “phantom” taxable income even though you broke even.

The deduction covers all gambling activity: losing lottery tickets, casino losses, and sports betting losses combined. You need documentation for anything you claim, including losing tickets, account statements, and contemporaneous records. Gambling operators report winnings to the IRS but do not report losses, so the burden of proof is entirely on you.

Lump Sum vs. Annuity: How the Choice Changes Your Tax

Jackpot games such as Mega Millions, Powerball, and Illinois Lotto let winners take either a lump sum or annuity payments over 30 years. Some instant-ticket top prizes pay over 20 years.⁵

The tax consequences are very different. A lump sum piles the entire prize into one tax year and almost always drives the winner into the top 37% federal bracket. An annuity spreads the income across decades, and each annual payment is taxed only in the year received. Depending on your other income, individual payments may fall in lower brackets. The tradeoff: tax rates could rise over 30 years, and you give up control of the full sum upfront.

The decision has a hard deadline. Winners of Lotto, Mega Millions, or Powerball jackpots must elect the lump sum within 60 days of the drawing date. Miss that window and the prize pays as an annuity with no option to change.⁵

W-2G Reporting and Group Wins

For 2026, the federal W-2G reporting threshold rose to $2,000 (up from $600), subject to conditions that vary by game type.⁶ Illinois still requires state withholding on lottery prizes of $1,000 or more, and the lottery issues a W-2G reflecting the amount withheld.³

Whether or not you receive a W-2G, all gambling income is taxable and must be reported. A $400 scratch-off win doesn’t generate a form, but it still belongs on your return.

When a group shares a winning ticket, the person who claims the prize must file IRS Form 5754 to identify each group member and their share.⁷ The lottery then issues separate W-2G forms to each member for prizes up to $25,000; for prizes above that, the Illinois Comptroller’s Office handles payments and issues the forms.⁵ Skip the 5754 and the entire prize gets reported under one Social Security number, leaving that person on the hook for tax on money they didn’t keep.

Debt Intercepts Before You’re Paid

Even after tax withholding, your check may shrink further. Illinois can intercept lottery prizes to satisfy overdue child support, debts owed to state agencies, non-wage garnishments, and criminal restitution orders.⁸ The Illinois Comptroller’s Office coordinates the offsets. For back child support, the Department of Healthcare and Family Services certifies the amount, and the Comptroller pulls it from the prize before payment. For annuity winners, the offset applies to each installment until the debt is cleared.

If You Receive Public Benefits

A lottery win can end means-tested benefits. Under federal rules from the 2014 Farm Bill, a SNAP household that wins a “substantial” cash prize loses eligibility immediately. Substantial means a single cash prize equal to or greater than the SNAP resource limit for elderly or disabled households, adjusted annually.⁹ The household stays ineligible until it again meets the program’s resource and income tests. States are required to work with lottery and gaming entities to identify recipients who receive large winnings.¹⁰ Medicaid and TANF apply similar income and resource tests. Report the win promptly; not reporting can lead to repayment demands and fraud penalties.
