Missouri Powerball Tax Calculator: How Much Would You Keep?
Estimate a Missouri Powerball cash payout after federal and Missouri income taxes. See the 24% federal withholding and 4% Missouri withholding separately from the estimated final federal and State tax.
Missouri Withholds 4%, but the 2026 Top State Rate Is 4.7%
Missouri Lottery currently withholds 4% Missouri State tax from prizes of $600.01 or more. Missouri DOR's 2026 tax schedule, however, reaches a 4.7% marginal rate once Missouri taxable income exceeds $9,436. A Powerball-sized prize therefore can leave additional Missouri tax due after the Lottery withholding.
Missouri withholding
The Lottery deducts 4% Missouri State tax at payment on prizes of $600.01 or more. That is a prepayment, not the final tax calculation.
Top Missouri rate
The 2026 Missouri schedule tops out at 4.7%, and a giant jackpot puts virtually all additional taxable income into that top marginal band.
No earnings tax added
Kansas City and St. Louis earnings taxes target earned compensation and business profits, so this page does not apply them to a personal Lottery windfall.
Missouri is another good example of why withholding and final liability must stay separate. Simply subtracting 24% federal + 4% Missouri can make a jackpot look more spendable than the final tax calculation suggests.

Missouri Powerball Withholding Rates
Missouri Lottery currently says it withholds 4% Missouri State tax on prizes of $600.01 or more and 24% federal tax on prizes of more than $5,000. It also warns that winners may owe additional tax or receive a refund depending on personal income.
| Tax layer | Withholding | Threshold | How MLL treats it |
|---|---|---|---|
| Federal | 24% | Prizes of more than $5,000 under current Lottery guidance | Initial withholding only; final federal liability is calculated separately. |
| Missouri | 4% | Prizes of $600.01 or more | Credit toward final Missouri tax; additional State tax can remain due. |
Withholding is not final liability. Missouri's 4% claim-time deduction is lower than the 4.7% top marginal rate in the 2026 individual schedule, while federal 24% withholding is also below the top federal marginal rate.
Missouri's 2026 Schedule Tops Out at 4.7%
Missouri's 2026 withholding formula publishes an annual taxable-income schedule beginning at 0%, then stepping through 2%, 2.5%, 3%, 3.5%, 4%, 4.5% and finally 4.7% above $9,436. For a Powerball-sized prize, virtually all additional Missouri taxable income sits in the 4.7% marginal band.
What the Missouri calculation includes
- 2026 Missouri progressive rates from 0% through 4.7%.
- 2026 standard deduction: $16,100 Single/MFS.
- 2026 standard deduction: $32,200 MFJ/Combined.
- 2026 standard deduction: $24,150 Head of Household.
- Missouri tax with the prize minus Missouri tax on entered other income alone.
The progressive calculation matters even though the brackets are tiny relative to a jackpot. MLL still runs the actual bracket structure rather than just multiplying every dollar by 4.7%.
Why This Calculator Does Not Add the 1% City Earnings Tax
Kansas City and St. Louis each have a 1% earnings tax, but those local taxes are defined around salaries, wages, commissions and other compensation earned for work, plus business net profits. A personal Lottery windfall is not treated here as earned compensation or business net profit.
Kansas City
Kansas City's own guidance calls the levy a 1% tax on earned income such as salaries, wages, commissions, tips and other compensation, plus business net profits.
St. Louis
St. Louis describes its 1% individual earnings tax through residents' and employees' earnings and employer wage withholding.
Lottery model
MLL therefore does not add a Kansas City or St. Louis earnings-tax percentage to a personal Powerball jackpot.
What If You Buy the Winning Powerball Ticket in Missouri but Live Elsewhere?
Missouri law expressly includes reportable winnings from a wager placed in the Missouri Lottery as Missouri-source income for nonresidents. Missouri's nonresident return then uses a Missouri-income percentage approach, so the exact final State liability depends on the winner's full income picture.
The calculator runs the 2026 progressive Missouri schedule directly for a same-state resident.
The page shows the federal result and Missouri withholding but avoids inventing a final nonresident/home-state combination without the exact residence-state facts.
Missouri Powerball Cash Option vs. Annuity
Missouri Lottery says Powerball jackpot prizes of $1 million and higher can be paid either in 30 annual payments or as a lump sum. This page models the one-time cash option.
Cash option
The official current Powerball cash value is the starting point for the one-time payout estimate.
Annual payments
Missouri Lottery says Powerball jackpot prizes can alternatively be paid in 30 annual installments.
Both choices are taxable
Federal and Missouri tax still matter; the timing of income changes under an annuity.
