This is an estimate, not tax advice. It assumes you are a U.S. citizen or resident filing single, this prize is your only income, and you take the standard deduction. A nonresident alien is withheld at 30% federal, not 24%. The state where the ticket was sold can tax a nonresident; these figures are for a resident who bought the ticket at home, except in states that do not sell the games. Puerto Rico and the U.S. Virgin Islands sell Powerball but follow their own tax rules and are not covered. County, city, and school-district income taxes are included only for New York City, Yonkers, Maryland counties, and the Portland area.
Federal withholding is 24% on prizes over $5,000. The final federal bill uses the 2026 brackets for a single filer, 10% up to 37% above $640,600 of taxable income, after the $16,100 standard deduction. Each annuity payment is taxed as its own year. Other income would push more of the prize into the top bracket.
Both games pay the annuity as 30 checks over 29 years, each 5% larger than the year before. The cash value is the lump sum the lottery is offering, not a guess.
Ohio. Ohio moved to a flat 2.75% on nonbusiness income over $26,050 for 2026, and the lottery withholds exactly 2.75% (the statute says so). Many Ohio cities have their own income tax. Those are not included. Flat 2.75% over $26,050, Tax Foundation 2026 (H.B. 96). Withholding: Ohio Revised Code § 5747.062, 2.75% for calendar year 2026 and thereafter on lottery prizes that must be reported to the IRS. Municipal income tax excluded.
Federal: IRS Rev. Proc. 2025-32, 2026 inflation adjustments (single brackets 10%, 12%, 22%, 24%, 32%, 35%, and 37% above $640,600 of taxable income; $16,100 standard deduction) and the January 2026 Form W-2G instructions (24% regular gambling withholding on lottery proceeds over $5,000).
