Does Missouri Tax Lottery Winnings? Withholding, Lump Sum, Losses

Yes, Missouri does tax lottery winnings. The state treats a prize as ordinary income and applies its graduated income tax, which tops out at 4.70 percent for tax year 2026. Federal tax stacks on top and can reach 37 percent on a large jackpot. The Missouri Lottery withholds some tax before it hands over your check, but that withholding almost never covers the full bill, so most winners owe more when they file.

How Missouri Taxes Your Prize

Missouri starts with your federal adjusted gross income and makes a few state-specific adjustments.1Missouri Revisor of Statutes. Missouri Revised Statutes Section 143.121 – Missouri Adjusted Gross Income Because federal law already treats gambling winnings as gross income, your lottery prize flows into the Missouri return automatically. There is no special line or separate schedule. It is simply added to your wages, interest, and other income for the year.

For 2026, Missouri’s brackets start at 2 percent and climb to 4.70 percent on income above roughly $9,436. Any meaningful lottery prize will push at least part of your income into that top bracket. The standard deduction reduces taxable income before the rate schedule applies: $16,100 for single filers, $32,200 for married couples filing jointly, and $24,150 for head of household.2Missouri Department of Revenue. 2026 Missouri Withholding Tax Formula

If you live elsewhere but bought the winning ticket in Missouri, you still owe Missouri tax on that prize and should file a Missouri nonresident return.

The Federal Layer

Federal law defines gross income as “all income from whatever source derived,” and lottery winnings sit squarely inside that definition.3Office of the Law Revision Counsel. 26 U.S. Code 61 – Gross Income Defined The top federal rate for 2026 is 37 percent, which kicks in above $640,600 of taxable income for a single filer and $768,700 for a married couple filing jointly.4Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026 A seven- or eight-figure jackpot clears those thresholds in a single year, so most of the prize is taxed at or near 37 percent.

Smaller prizes still add to your regular income and can push you into a higher bracket than you normally sit in. Run the numbers against your full-year income before you assume the withheld amount is enough.

What the Lottery Withholds Up Front

The Missouri Lottery deducts tax before it pays you, in two layers with different triggers:

Combined, that is 28 percent on a large prize. But the federal top rate is 37 percent and Missouri’s top rate is 4.70 percent, so the withholding is a down payment, not a settlement. If you win big, expect to write another check at filing time.

A separate rule governs paperwork. Starting in 2026, the federal reporting threshold on Form W-2G rose to $2,000, up from the long-standing $600, and it will adjust annually for inflation.7Internal Revenue Service. Instructions for Forms W-2G and 5754 – Rev. January 2026 Even if your prize falls under that threshold and you never see a W-2G, the winnings are still taxable and you are still required to report them.

Lump Sum or Annuity

Large jackpots let you choose between a single lump-sum payment and an annuity paid over about 29 years, and the choice changes your tax picture.

Take the lump sum and the full cash value counts as income in the year you receive it. For a multi-million-dollar prize, most of it is taxed at the top 37 percent federal rate plus 4.70 percent to Missouri. Take the annuity and only each year’s installment counts as that year’s income.8Internal Revenue Service. Publication 525 – Taxable and Nontaxable Income Spreading the income across decades can keep more of each payment out of the top bracket, depending on the prize size and your other income. The 24 percent federal withholding still applies to each annuity payment as it is made.

Interest that accrues on the unpaid annuity balance is itself taxable in the year you receive it.8Internal Revenue Service. Publication 525 – Taxable and Nontaxable Income

Estimated Payments to Avoid a Penalty

Because 28 percent withholding rarely matches what a big winner actually owes, both the IRS and Missouri can hit you with an underpayment penalty if you wait until April to settle up.

The IRS generally expects estimated tax payments if you will owe $1,000 or more beyond your withholding. You avoid the penalty by paying at least 90 percent of your current-year tax or 100 percent of last year’s tax (110 percent if your prior-year adjusted gross income was above $150,000).9Internal Revenue Service. Form 1040-ES – Estimated Tax for Individuals 2026 For a large windfall, the prior-year safe harbor is often the cleaner target if your pre-lottery income was modest. Federal payments are due April 15, June 15, September 15, and January 15 of the following year. If your prize hit mid-year, an annualized income installment method lets you concentrate payments in the quarters after you won.

Missouri sets a lower bar: you need to file a declaration of estimated tax if you expect to owe $100 or more in state tax after withholding.10Missouri Department of Revenue. 2026 Declaration of Estimated Tax for Individuals Almost any winner who kept 96 percent of a large prize after Missouri’s 4 percent withholding will owe more at the 4.70 percent top rate, so Form MO-1040ES belongs on your calendar.

Deducting Gambling Losses

You can deduct gambling losses on your federal return, but only up to the amount of gambling winnings you report, and only if you itemize on Schedule A instead of taking the standard deduction.11Internal Revenue Service. Topic No. 419 – Gambling Income and Losses You cannot simply net winnings against losses and report the difference. Winnings go in as income; losses come out as an itemized deduction.

The IRS requires records to back up any losses you claim, including dates, amounts, locations, and receipts or tickets. Without them, the deduction can be disallowed entirely.12Internal Revenue Service. Publication 529 – Miscellaneous Deductions

Splitting a Prize With a Group

If you won as part of a pool, the person who claims the prize files IRS Form 5754 listing each member’s name, taxpayer ID, and share. The lottery then issues a separate W-2G to each person for their share.7Internal Revenue Service. Instructions for Forms W-2G and 5754 – Rev. January 2026

Withholding and reporting thresholds look at the full prize before it is split, not at each person’s individual share. A $25,000 group win crosses the $5,000 federal withholding threshold even if each member ends up with a much smaller amount. Skip Form 5754 and the whole tax burden lands on the single claimant, which is a mess to unwind later.

A Note on Local Earnings Taxes

St. Louis and Kansas City each impose a 1 percent earnings tax, but it applies to wages and compensation, not to lottery prizes. The City of St. Louis lists gambling and lottery winnings as non-taxable for earnings tax purposes.13City of St. Louis. Taxable and Non-Taxable Items If you live or work in either city, confirm with the city’s revenue office, since local rules can shift.
