Lottery Tax Calculator — How Much of Your Winnings Do You Actually Keep?
You just won $500 million. Congratulations! Now here's the part nobody talks about until it's too late: you're not keeping $500 million. Not even close.
Between federal taxes, state taxes, and the lump sum discount, that headline jackpot shrinks fast. Let's break down exactly how much you actually take home.
The Two Big Choices
Lump Sum vs. Annuity
Every major lottery winner faces this decision:
- Lump Sum: Take ~60% of the advertised jackpot as one payment, right now
- Annuity: Get the full advertised amount, paid out over 29 annual payments
Most winners choose lump sum. There are good reasons for both.
Lump sum makes sense if:
- You can invest it at returns exceeding the annuity's effective rate (~4-5%)
- You want full control of your money
- You're concerned about state tax rate increases over 30 years
Annuity makes sense if:
- You want built-in spending discipline
- You'd rather have guaranteed income for life
- The effective rate of the annuity beats what you'd earn investing
Federal Taxes: 37%
The IRS treats lottery winnings as ordinary income. For any win over ~$600K, you're in the top bracket: 37% federal tax.
On a $500M jackpot (lump sum of $300M):
- Federal tax: $111 million
- Remaining: $189 million
That's before your state gets its cut.
State Taxes: The Map Matters
This is where it gets interesting. Your state of residence can save or cost you tens of millions:
No State Tax on Lottery Winnings
Texas, Florida, California, Washington, Wyoming, Tennessee, South Dakota, New Hampshire, Nevada, Alaska
Highest State Lottery Taxes
- New York: 10.9% (plus NYC adds another 3.876%)
- Maryland: 8.75%
- New Jersey: 8%
- Oregon: 8%
- Minnesota: 7.75%
What This Means in Real Money
| State | $500M Jackpot (Lump Sum) | After All Taxes | You Keep | |-------|-------------------------|----------------|----------| | Texas | $300M | $189M | 63% | | New York | $300M | $156.3M | 52% | | California | $300M | $189M | 63% | | Maryland | $300M | $162.8M | 54% |
A New York winner keeps $33 million LESS than a Texas winner on the same jackpot.

Pro Tips
- Check your state before you buy. If you live near a state border, knowing the tax difference is useful context.
- The advertised jackpot is the annuity number. The lump sum is always lower — usually around 60%.
- Consider a financial advisor before claiming. You have 60-180 days to claim in most states. Use that time.
- State taxes can change. If you choose annuity, your tax rate 15 years from now might be different than today.
The Bottom Line
Nobody wins the lottery and goes broke because of taxes. They go broke because of spending. But knowing your actual take-home number is step one of making smart decisions with a windfall.
