Lump sum: what an Iowa winner keeps
Take the cash option and you get the jackpot’s cash value — currently 41% of the advertised amount — in one payment. Federal tax takes 37%: the lottery withholds 24% when you claim, and the rest is due when you file. Iowa then takes its 3.8%.

Annuity: 30 payments over 29 years

How Iowa taxes lottery winnings
Iowa has a flat income tax, so a lottery prize is taxed at 3.8% from the first dollar — about $3.8 million of every $100 million in cash value.
Iowa’s 3.8% is the 8th-lowest state tax on lottery winnings among the 37 states and D.C. that tax them.
Iowa moved to a flat 3.8% income tax in 2025.
On the current jackpot, Iowa takes $7.3 million of the lump sum — money a winner in Texas or Florida, which don’t tax lottery prizes, would keep.
Iowa vs. neighboring states
What the current Powerball jackpot’s lump sum is worth after taxes in Iowa and next door. Buying a ticket across the state line doesn’t get you out of Iowa’s tax: you generally owe it as a resident, with a credit for tax paid to the state that sold the ticket.
Powerball taxes in Iowa: common questions
How much would an Iowa winner keep from a Powerball jackpot?
About 59.2% of the cash value. Federal tax takes 37% and Iowa takes 3.8%, so an Iowa winner keeps about $59.2 million of every $100 million in cash. With the annuity, the same 59.2% applies to the full advertised jackpot, paid over 30 years.
Does Iowa tax lottery winnings?
Yes. Iowa taxes lottery winnings as income at a flat 3.8%.
Should an Iowa winner take the lump sum or the annuity?
It depends on what you’d do with the money. The lump sum pays the cash value now — recently around 40–45% of the advertised jackpot — and you keep about 59.2% of it after taxes in Iowa. The annuity pays the whole advertised jackpot over 29 years in 30 payments, each 5% larger than the last, taxed as you receive them. Take the cash if you’d invest it at least as well as long-term Treasury bonds pay; take the annuity if you want protection from spending it too fast.
How much tax is withheld when you claim a Powerball prize in Iowa?
The lottery withholds 24% for federal tax on any prize over $5,000. A jackpot puts you in the 37% bracket, so you’ll owe roughly another 13% when you file. Iowa may also withhold state tax when you claim; any balance of its 3.8% is due with your state return.
When is the Powerball drawing, and how much is a ticket?
Powerball draws every Monday, Wednesday and Saturday at 10:59 p.m. Eastern. A ticket costs $2, and the odds of hitting the jackpot are 1 in 292,201,338.
