"How much tax on a $1 billion lottery win?" "How would a $1,000,000 lump sum be taxed?" "How much would you actually get from $1.5 billion?" These are among the most-searched lottery questions in America — and the honest answer is that taxes (and the lump-sum discount before them) take a much bigger bite than most people expect. Here's the breakdown for every jackpot size, including why where you live changes everything.
First: the advertised number is not the cash number
Before a single dollar of tax, understand that a "$1 billion jackpot" is the annuity value — 30 payments over 29 years. If you take the cash (and about 95% of winners do), you get the lump-sum cash value, which is usually around half of the advertised amount. So a $1 billion jackpot is roughly $450–$520 million in cash before taxes even start. We compare the two options in detail in Lump Sum vs Annuity.
The two layers of tax
Federal tax hits everyone. The IRS withholds 24% from any lottery prize over $5,000 up front — but a jackpot pushes you into the top 37% federal bracket, so you owe the difference (another ~13%) when you file. That gap surprises a lot of winners.
State tax is where your zip code matters enormously. It ranges from 0% to about 10.9% of the prize. States with no tax on lottery winnings include Florida, Texas, Tennessee, Washington, South Dakota, Wyoming, New Hampshire, and California (which exempts lottery prizes). At the other end, New York takes about 10.9% on top of federal. We rank all of them in our federal + state tax breakdown.
How much tax on a $1 billion lottery win?
Take a $1 billion advertised jackpot, lump-sum cash of roughly $500 million:
- Federal at 37%: about $185 million.
- State: $0 in Florida or Texas; roughly $55 million in New York.
- Take-home: roughly $315 million in a no-tax state, dropping toward $260 million in a high-tax state.
So a "$1 billion" win realistically nets a Florida resident somewhere around $300+ million — life-changing, but less than a third of the headline.
How would a $1,000,000 lump-sum prize be taxed?
A flat $1 million prize is simpler. The lottery withholds 24% ($240,000) immediately, but the win stacks on top of your other income and most of it lands in the 37% bracket, so your true federal bill is closer to $370,000. In Florida, with no state tax, you'd keep roughly $630,000. In New York, knock off another ~$109,000. The big takeaway: don't spend the "after 24%" number — set aside for the bracket gap.
How much would you get from a $1.5 billion jackpot?
Lump-sum cash on a $1.5 billion advertised jackpot is roughly $700–$750 million. After 37% federal, you're left with about $450–$475 million in a no-tax state, less wherever state tax applies. Choose the annuity instead and you'd receive the full $1.5 billion across 30 years, taxed as each payment arrives.
The Florida advantage
For the Miami and wider Florida audience asking these questions: Florida is one of the best states in the country to win, precisely because it takes zero state tax on lottery prizes and offers a 90-day anonymity window for prizes of $250,000+. On a billion-dollar jackpot, that no-state-tax status alone can be worth tens of millions versus winning in a high-tax state. See the full ranking in best states to buy a lottery ticket.
