Lump sum: what a Wisconsin winner keeps
Take the cash option and you get the jackpot’s cash value — currently 40% 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. Wisconsin then takes its 7.65%.
| Lump sum | Amount |
|---|---|
| Cash value | $139,600,000 |
| Federal income tax (37%) | −$51,652,000 |
| Wisconsin state tax (7.65%) | −$10,679,400 |
| You keep | $77,268,600 |
Annuity: 30 payments over 29 years
The annuity pays the full advertised jackpot: one payment when you claim and 29 more once a year, each 5% bigger than the last. Each payment is taxed in the year you receive it, so a Wisconsin winner keeps about 55.35% of every check.

How Wisconsin taxes lottery winnings
Wisconsin taxes lottery winnings as ordinary income at up to 7.65%. On a jackpot-size prize nearly every dollar falls in the top bracket, so plan on the full 7.65% — about $7.65 million of every $100 million in cash value.
Wisconsin’s 7.65% is the 9th-highest state tax on lottery winnings among the 37 states and D.C. that tax them.
On the current jackpot, Wisconsin takes $10.7 million of the lump sum — money a winner in Texas or Florida, which don’t tax lottery prizes, would keep.
Wisconsin vs. neighboring states
What the current Mega Millions jackpot’s lump sum is worth after taxes in Wisconsin and next door. Buying a ticket across the state line doesn’t get you out of Wisconsin’s tax: you generally owe it as a resident, with a credit for tax paid to the state that sold the ticket.
Mega Millions taxes in Wisconsin: common questions
How much would a Wisconsin winner keep from a Mega Millions jackpot?
About 55.35% of the cash value. Federal tax takes 37% and Wisconsin takes 7.65%, so a Wisconsin winner keeps about $55.35 million of every $100 million in cash. With the annuity, the same 55.35% applies to the full advertised jackpot, paid over 30 years.
Does Wisconsin tax lottery winnings?
Yes. Wisconsin taxes lottery winnings as income at up to 7.65%.
Should a Wisconsin 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 55.35% of it after taxes in Wisconsin. 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 Mega Millions prize in Wisconsin?
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. Wisconsin may also withhold state tax when you claim; any balance of its 7.65% is due with your state return.
When is the Mega Millions drawing, and how much is a ticket?
Mega Millions draws every Tuesday and Friday at 11 p.m. Eastern. A ticket costs $5 — every play includes a built-in 2X to 10X multiplier on the non-jackpot prizes — and the odds of hitting the jackpot are 1 in 290,472,336.
