Illinois sports-bet winnings: what a recreational bettor reports

A U.S. tax-resident recreational bettor in Illinois generally has federal ordinary-income tax on gambling winnings plus Illinois income tax. Illinois's individual rate is 4.95%; the federal rate depends on the entire return. 24% is conditional federal withholding, not a universal or final tax rate. The 20%–40% Illinois operator taxes and Chicago's 10.25% tax are taxes on operators, not extra personal income-tax rates for bettors.

This guide was checked October 5, 2026. “Tax year 2026” means income received during 2026; a return for that year is filed in 2027. It addresses U.S. tax-resident recreational sports bettors, not professional gamblers or nonresident aliens.

The short answer: payer, base, and rate

Your personal tax, tax withheld from a qualifying payout, and taxes imposed on a sportsbook are different calculations. They should not be added into one supposed “sports-bet tax rate.”

Illinois's 4.95% rate is reflected in the Illinois Department of Revenue withholding tables effective January 1, 2026. It is useful for an incremental illustration, but it is not a separate final tax invoice for every winning ticket.

Define the numbers before adding them

A stake is the amount put at risk on one wager. A payout is the amount paid on a winning wager and may include the returned stake. For this guide, the gain on a winning bet is payout minus the returned winning stake. The returned stake is not part of annual gain G.

A losing bet is a stake actually lost. Do not count a stake returned in a winning payout as a loss. For annual tracking, calculate G by adding gains on all winning bets and calculate L by adding all actually losing stakes. Do not use bank withdrawals, app balance changes, all payouts, total handle, or a single annual net result as G.

The distinction matters because federal reporting starts with all winnings. Losses, if allowed, are a separate itemized deduction rather than a self-netted number on the return. The IRS says all gambling winnings are taxable and advises taxpayers to keep records of wins and losses in Tax Topic 419.

W-2G, withholding, and final tax are separate

A W-2G is an information return, not a tax exemption or final tax calculation. Under the IRS Instructions for Forms W-2G and 5754 and the January 2026 W-2G instructions PDF, a sports wager generally reaches the W-2G reporting rule when the payment is at least $2,000 and at least 300 times the wager, subject to special aggregation rules for identical wagers.

Regular federal withholding is a separate test. For sports betting, it applies where the net winnings exceed $5,000 and the 300-to-1 condition is met. A valid taxpayer identification number, payment method, and aggregation facts can matter; the examples below assume cash payment, a valid TIN, no identical wagers to aggregate, and no other-state withholding.

IRS sports-wager instructions showing W-2G reporting and withholding conditions

English-language IRS sports-wager material from January 2026 showing that reporting and withholding have separate conditions.

For the $20 / $6,020 case, federal withholding is 24% of $6,000 = $1,440. Illinois withholding is 4.95% of $6,000 = $297, so cash disbursed is $6,020 − $1,440 − $297 = $4,283. That $4,283 includes the returned $20 stake. Illinois generally requires withholding when federal withholding is required, as explained by IDOR's gambling-withholding guidance.

The $5,000 gain in the first row remains reportable in the bettor's annual winnings even though there is no W-2G; the returned $50 stake is excluded from annual gain. Conversely, the $1,440 withheld in the third row is not proof that the bettor's final federal rate is 24%; it is a payment credit against the federal liability calculated from the full return.

Federal losses in 2026 and Illinois's different rule

For 2026, the federal gambling-loss deduction for a recreational bettor follows D = min(0.9 × L, G). First multiply documented losses by 90%, then cap that amount at winnings. It is not 0.9 × min(L, G). The deduction requires itemizing; it cannot be combined with the standard deduction. See the 2026 version of IRS Publication 505.

The G − D column is only an illustration of the gambling portion; it is not the taxpayer's full taxable income. In the first example, cash gambling results are even but the federal 90% rule leaves $1,000 after the deduction. In the second, the bettor has a $2,000 cash loss but the deduction stops at $10,000. Neither example promises a refund or permits the taxpayer to claim both the standard deduction and itemized gambling losses.

Illinois does not permit a gambling-loss deduction on the Illinois return. A federal itemized deduction therefore does not reduce the Illinois illustration above; consult IDOR's additions and subtractions information. For the broader federal loss-rule discussion, see the 2026 gambling-loss guide.

A safe walkthrough of the main calculator

Use this pre-filled calculator example only as a simplified no-loss illustration. Its stated assumptions are: single U.S. tax resident, ordinary income, no itemizing, no other credits, no other losses, $0 gambling losses, and $0 already withheld.

The field labeled “Other taxable income” should be entered as $70,000 in this example, but interpret that input as income before the $16,100 standard deduction. It is not an already-reduced taxable-income number. The baseline after the standard deduction is $53,900.

1. Enter annual winnings of $10,000 as G, the total gains from winning bets rather than payouts or withdrawals.
2. Enter losses of $0 and leave itemizing off.
3. Select Illinois, Single, tax year 2026, other income of $70,000, and federal withholding of $0.
4. Read the result as an incremental illustration: $2,200 federal tax, $495 Illinois tax, and $2,695 total incremental tax.
5. The displayed $7,305 is the $10,000 gain less the illustrated $2,695 tax. The tax is exactly 26.95% of $10,000, and the remaining $7,305 is 73.05%; the interface rounds the tax rate to 27.0%.

The federal result reflects the simplified fact pattern in which the additional $10,000 falls in the 22% band for a single taxpayer. The $16,100 standard deduction and relevant 2026 bracket information are in the IRS 2026 inflation-adjustment release. This result is not a full return, a refund estimate, a bankroll-profit calculation, or a recommendation to alter a wager.

Limits of the main calculator: this walkthrough uses only the no-loss, non-itemizing fact pattern. The main calculator models losses incorrectly when L > G and improperly subtracts the standard deduction when itemizing is selected. Do not use it to choose itemizing versus the standard deduction or to calculate actual loss facts. It is not a complete return, refund estimate, or bankroll-profit calculation.

Do not use the embedded block immediately below for ANY tax, withholding, W-2G/reporting, or payout calculation, including a no-loss calculation; its TOTAL TAX and NET PAYOUT outputs must not be relied upon. It is a separate legacy component: it does not test the 300-to-1 condition, retains a stale $600 W-2G reference, and automatically applies 24% above $5,000. It has no fields for annual losses, itemizing, other income, or tax year, so it cannot reproduce the $2,200 example above or decide W-2G reporting, withholding, payout, or filing. Its Chicago claim of $0.50 online and $0.25 retail is false: the actual state per-wager operator tax is $0.25 on the first 20 million online wagers and $0.50 on subsequent online wagers, with no retail per-wager tax. Chicago's 10.25% is operator AGR tax, not player tax. Use the bounded main calculator above for the no-loss example and consult current IRS rules.

Records and filing workflow

Build the year from wager-level records, not from a bank withdrawal or only the W-2Gs you received. Download each sportsbook's annual transaction history and every W-2G, then compare the exports with your own log.

Your log should show the date, sportsbook, stake, payout, gain on each winning bet, losing stake, fees, federal withholding, and state withholding. A W-2G may cover only some wins; it is not a complete substitute for annual G. Keep the downloads, wager confirmations, W-2Gs, and withholding evidence with the return.

Blank IRS Form W-2G Copy B with winnings and withholding boxes

Blank official Form W-2G Copy B fragment. Box 1 reports winnings, box 4 reports federal income tax withheld, box 13 identifies the state, box 14 reports state winnings, and box 15 reports state tax withheld; no taxpayer data is shown.

1. Add gains from winning bets to determine G; separately add actually losing stakes to determine L.
2. Report all gambling winnings on the federal return's Schedule 1. Do not self-net winnings and losses there.
3. If itemizing and supported by records, calculate the 2026 federal loss deduction under the 90% rule and claim it on Schedule A. Do not combine it with the standard deduction.
4. Reconcile every W-2G to the records. Box 4 is federal withholding, while box 15 is state withholding; they are separate credits.
5. File Illinois Form IL-1040 as an Illinois resident. A nonresident with required Illinois-source reporting generally uses IL-1040 with Schedule NR.
6. Use the official forms and instructions for the tax year being filed. If withholding appears insufficient during the year, check whether estimated payments are appropriate through the IRS's estimated taxes guidance and Form 1040-ES. Illinois lists current individual materials, including IL-1040-ES, on its individual income-tax forms page. This is a practical check during the year, not a promise that waiting for the annual return is sufficient.

The blank 2026 Form W-2G Copy B shows the form's boxes, and the IRS W-2G instructions explain them.

Residency, out-of-state bettors, and Chicago

Illinois residents include gambling income in their Illinois return. Nonresidents can also have Illinois-source gambling income: IDOR says that gambling winnings received in Illinois have been taxable by Illinois regardless of residency since 2019 in its official answer on gambling income.

A nonresident is not necessarily a federal nonresident alien. If the bettor lives in another state, the home state may have its own reporting rule, and a credit for Illinois tax is not automatic or necessarily complete. Nonresident aliens, professional-gambling facts, multi-state income, and contested resident-state credits warrant review by a tax professional who can see the complete federal and state filings.

Living in Chicago does not impose a personal 10.25% tax on sports-bet winnings. Chicago's Municipal Code section 4-156-973 applies the 10.25% rate to specified licensed operators' adjusted gross receipts, not to the bettor's individual income-tax return.

Operator tax bands and the online per-wager tax

Illinois's current sports-wager operator statute has used marginal AGR bands of 20%, 25%, 30%, 35%, and 40% since July 1, 2024, for both online and retail wagering. Subsection (d) online AGR and subsection (d-5) retail AGR use the same bands but separate tax bases. AGR is operator revenue, not a bettor's handle, payout, gain, or taxable income. The current authority is 230 ILCS 45/25-90, including P.A. 104-468 effective June 16, 2026.

These are marginal bands, not one rate applied to all AGR. At $60 million of AGR in one stream, for example, tax is $14 million: $6 million on the first $30 million at 20%, $5 million on the next $20 million at 25%, and $3 million on the next $10 million at 30%. By contrast, combined $30 million online AGR and $30 million retail AGR produces $12 million in base tax before other operator taxes. This is an operator example, not a bettor-tax calculation.

Since July 1, 2025, the statute has separately imposed an online-only per-wager operator tax of $0.25 on the first 20 million online wagers by a licensee in a fiscal year and $0.50 on subsequent online wagers. The fiscal year runs July 1 through June 30, and retail wagers are not subject to this per-wager tax. The Illinois Gaming Board's June 17, 2025 FAQ is historical explanatory material; the current statute is the controlling source.

Illinois Gaming Board historical online-only per-wager tax excerpt

English-language Illinois Gaming Board excerpt dated June 17, 2025, describing the online-only per-wager tax rather than retail wagering. It is an operator obligation, not a bettor's personal income tax.

The tax is an operator obligation and does not itself establish that a particular sportsbook charges a customer fee. If an operator's current terms separately show a $0.50 customer charge, 100 wagers would total $50. Against a $2 stake, that amount equals 25% of the stake; against a $50 stake, it equals 1%. This is only a conditional cost illustration, not a claim about any operator's current pricing and not an income tax. Chicago's 10.25% operator tax is discussed separately because it has a different tax base and is not an additional bar in the AGR-band chart.
