Mega Millions, after tax
What you’d actually keep of a $800M Mega Millions jackpot, taken as cash, claimed in Florida. The other $127.3M is tax.
Line by line
| Advertised jackpot (Mega Millions) | $800M |
|---|---|
| Cash value — what the prize really is | $344.2M |
| Federal income tax (top bracket 37%) | −$127.3M |
| Florida — no state income tax | — |
| What lands in your account | $216.9M |
The lottery withholds 24% up front. The top federal bracket is 37% — the remaining 13% comes due on your return, which is where people get caught. The advertised jackpot is the headline number, paid out over 30 years; every figure here is the cash value — the lump sum you’d actually be paid. Figures assume a single winner in the top bracket and no other income.
Price it for you
Mega Millions and Florida carry over — you won’t re-enter them.
Before Tuesday’s draw
Everybody guesses the number. Almost nobody has an answer for the rest.
Someday takes $216.9M and makes you spend it — the people, the houses, what you keep for yourself — then shows you the year that produces and what it says about you.
About four minutes. Free, and no account until you want to save it.
The 24% withheld is not the bill
The lottery withholds 24% federal at the moment you claim. The top federal bracket is 37%, and a jackpot puts you there instantly — so roughly 13% of the cash value is still owed when you file.
On this $344.2M cash value that gap is about $44.7M. It is the single most common surprise for winners, and it is entirely predictable.
Mega Millions after taxes, by state
cash option · $800M jackpotRates are each state’s final income-tax rate on lottery prizes for a single filer claiming in that state — the total state liability, not the amount withheld at claim — applied to the cash value. Every row is state-only. New York City and Yonkers residents owe a local tax on top of New York’s state rate; it is computed in the configurator on Someday’s New York page, never in this table.
Next drawing: Tue, Jul 28
