ChamTax is a free calculator that shows the actual after-tax take-home amount for US Powerball and Mega Millions jackpots. Here's how a Powerball or Mega Millions win is taxed for a Alabama resident — combining the federal tax hit with Alabama's own lottery tax rate (5%).

$1,000,000 win in Alabama, single filer estimate
Alabama taxes lottery winnings at a 5% top state rate in this calculator's model, applied on top of the federal tax bite. This applies based on residency, not on where the ticket was purchased — see the note below.
Alabama is one of five states with no lottery of its own — Alabama, Alaska, Hawaii, Nevada, and Utah don't sell Powerball or Mega Millions tickets. An Alabama resident who wins by buying a ticket while in a neighboring state is generally still subject to Alabama's state income tax on that win, because state income tax follows residency, not where the ticket was bought.
Whichever state you live in, the IRS automatically withholds a flat 24% from a lottery prize the moment it's paid out. That 24% is only the up-front withholding, though — it is not the final bill. For a jackpot-sized win, the actual top federal marginal rate is 37%, so most jackpot winners end up owing a significant additional amount when they file their return the following year. This calculator (like the quick-answer box above) shows the true 37% outcome, not just the smaller 24% withheld at the register, so the number you see here is the one to actually plan around.
Powerball and Mega Millions winners choose between a smaller lump-sum cash payout today or the full advertised jackpot paid out as an annuity over 29-30 years. Choosing lump sum vs. annuity changes the size and timing of the payments, but it does not change the tax rates that apply — federal and Alabama state tax (where applicable) are calculated the same way either way, just against a smaller total (the lump sum) or a series of smaller annual payments (the annuity). Most jackpot winners historically choose the lump sum. This is general information, not financial advice — the better choice depends on your own circumstances.

Open the calculator →On a $1,000,000 win, the IRS withholds 24% immediately, but a jackpot-sized prize actually falls in the top 37% federal bracket, so a Alabama resident should plan for 37% federal tax — $370,000 — plus Alabama's state tax of 5% ($50,000), for an estimated take-home of about $580,000. Use the calculator above for other amounts.
There's no single right answer — it depends on your own financial situation, and this isn't financial advice. A lump sum gives you the full (smaller) amount immediately, which you could invest yourself, while an annuity spreads the full advertised jackpot over 29-30 years of payments. Tax rates apply the same way to either option; the difference is the total amount and the timing, not the rate.
Yes. You don't need US citizenship or residency to claim a US lottery prize — anyone who legally bought the winning ticket can collect. However, nonresident aliens (non-US-citizens without US tax residency) face a flat 30% federal withholding rate instead of the 24%-withheld/37%-top-rate treatment that applies to US residents.
The IRS withholds 24% immediately when a lottery prize is paid out. But 24% is just the withholding — for a jackpot-sized win, the real top marginal federal tax rate is 37%, so most winners owe additional federal tax beyond the 24% withheld once they file. Nonresident aliens instead face a flat 30% withholding rate.
