Tax and claiming
Four deductions stand between a US headline jackpot and your bank account. Worked in full, in order.
US jackpots are advertised at their largest possible number. Getting from that number to a bank balance involves four steps, and each one is larger than most people expect.
The advertised figure is the annuity — the total of payments made over roughly three decades. The cash value is what the operator actually holds today, and in recent jackpots it has run at roughly 45–55% of the advertised figure.
Take a $100,000,000 advertised jackpot at a 50% cash ratio:
Cash value: $50,000,000
Roughly half the headline has gone, and no tax has been charged yet. Which option is genuinely better depends on the implied discount rate — worked through in annuity vs lump sum and the lump sum vs annuity calculator.
The IRS requires 24% federal withholding on large gambling prizes, taken before you receive anything.
$50,000,000 × 24% = $12,000,000 withheld Received: $38,000,000
The critical point, and the one that catches winners out: this is an instalment, not the bill.
Lottery winnings are ordinary income. A prize of this size lands squarely in the top federal bracket of 37%, and the difference between that and the 24% already withheld falls due when you file.
Total federal tax: $50,000,000 × 37% = $18,500,000 Already withheld: $12,000,000 Still owed at filing: $6,500,000
After federal tax: $31,500,000
A winner who treats the $38,000,000 they received as spendable is $6.5 million short at filing time. This is the single most common US lottery tax mistake.
Most states tax lottery winnings as income. A handful, including Florida and Texas, levy no state income tax at all. Rates elsewhere run to roughly 10.9%.
No-state-tax state (e.g. Florida, Texas): Take-home: $31,500,000 — 31.5% of the advertised jackpot
High-tax state (10.9%): $50,000,000 × 10.9% = $5,450,000 Take-home: $31,500,000 − $5,450,000 = $26,050,000 — 26.1% of the advertised jackpot
| Step | Amount | Running total |
|---|---|---|
| Advertised jackpot | $100,000,000 | $100,000,000 |
| Cash value (~50%) | −$50,000,000 | $50,000,000 |
| Federal tax at 37% | −$18,500,000 | $31,500,000 |
| State tax at 10.9% | −$5,450,000 | $26,050,000 |
A $100 million jackpot delivers roughly $26–32 million, depending on your state — between a quarter and a third of the advertised number.
Everything above assumes a single winning ticket. If two tickets match, halve the cash value before any of the tax arithmetic: a shared $100 million jackpot in a high-tax state is around $13 million each.
Sharing is not unusual — it rises sharply with jackpot size, because sales rise with it. The Poisson model behind that is in how prize pools are split, and the effect on expected value in positive expected value in a lottery.
Non-resident aliens generally face 30% federal withholding on US gambling winnings, and may owe tax at home as well depending on treaty relief. See winning a foreign lottery.
The deductions are not negotiable, but the sequencing is. Everything that can be done — the annuity decision, state residency questions, whether a trust can claim in your state — has to be settled before you present the ticket. That is the argument in the first 72 hours and claiming anonymously: the structures used.

This is general information, not tax advice. State rules vary in detail — some states withhold at different rates than their headline income tax rate — and on sums of this size professional advice pays for itself many times over.
