The reason you only get about half of lottery winnings — and often less — is that two separate reductions stack on top of each other. First, the advertised jackpot is an annuity total paid over 29 years, and the immediate cash option is roughly half that headline number. Then federal, state, and sometimes local taxes take a large share of what remains. On a $500 million advertised prize, a winner in a moderately taxed state typically ends up with around $145 million, or about 29% of the number on the billboard.
The Advertised Jackpot Is an Annuity Total
The number you see advertised is not cash on hand. It’s the total of 30 graduated payments the lottery would distribute over 29 years if you choose the annuity option, with each annual payment growing by about 5% to keep pace with inflation. Lottery commissions can promise this total because they invest the prize pool in government bonds and let interest compound over three decades.
Almost every winner takes the cash option instead. That option pays the present value of the investment pool — the money the lottery actually has on hand the day of the drawing. For a $500 million advertised jackpot, the cash value might be around $250 million.1Mega Millions. Difference Between Cash Value and Annuity That immediate discount happens before any tax authority takes a dollar, and it is the single biggest reason the final check looks so much smaller than expected.
Federal Withholding Takes 24% Right Away
Once the cash value is set, federal law requires the lottery to withhold 24% of any prize over $5,000 before you see a check.2Office of the Law Revision Counsel. 26 USC 3402 – Income Tax Collected at Source On a $250 million cash payout, that is $60 million gone before the wire transfer arrives. The lottery commission sends you a Form W-2G documenting the win and the amount withheld, with a copy to the IRS.3Internal Revenue Service. Instructions for Forms W-2G and 5754
Lottery winnings are not subject to Social Security or Medicare payroll taxes. Those apply only to earned income like wages, so the 7.65% FICA hit that shrinks a paycheck does not apply to a jackpot.
The Real Federal Tax Bill Is Closer to 37%
That 24% withheld at payout is only a down payment. Lottery winnings are taxed as ordinary income, and a major jackpot pushes almost all of the prize into the top federal bracket. For 2026, the highest marginal rate is 37%, which kicks in at $640,600 for single filers.4Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026 Virtually every dollar of a large jackpot sits above that threshold, so the effective federal rate lands very close to 37%.
You owe roughly 13 percentage points more than what was already withheld. On a $250 million cash payout, that’s about $32.5 million in additional federal tax due when you file. The IRS also expects quarterly estimated payments rather than a lump sum in April. The deadlines are April 15, June 15, September 15, and January 15 of the following year.5Internal Revenue Service.

State and Local Taxes Stack on Top
Most states want their share too. State income tax rates on lottery winnings range from under 3% to nearly 11%, depending on where you bought the ticket and where you live. Roughly a dozen states either have no income tax or specifically exempt lottery prizes, which can save a winner millions.
If you bought the ticket in a state where you don’t live, you may owe tax in both states. Most states offer a credit so you aren’t fully double-taxed, but the paperwork gets complicated. A handful of high-tax cities also impose their own income tax on top of the state rate, adding another 1% to nearly 4%. In the most expensive metropolitan areas, the combined state and local bite can exceed 13% of the cash payout. State taxes are typically withheld at payout, just like the federal amount.
What the Math Actually Looks Like
Here is how the numbers work on a $500 million advertised Mega Millions jackpot for a winner who takes the cash option and lives in a state with a 5% income tax:
- Advertised jackpot (annuity value): $500 million
- Cash option (roughly 50%): $250 million
- Federal withholding at 24%: −$60 million
- State withholding at 5%: −$12.5 million
- Check you receive: about $177.5 million
- Additional federal tax owed at filing (roughly 13% more): −$32.5 million
- Net after all taxes: about $145 million
That $145 million is roughly 29% of the $500 million headline. In a high-tax state, the final figure drops further. The common “you only get half” perception actually understates the reduction. Most jackpot winners keep less than a third of the advertised amount.
Cash vs. Annuity Changes the Tax Picture
Taking the cash means accepting roughly half the advertised prize immediately and paying tax on the entire amount in a single year. That pushes all of it into the highest federal bracket at once. The annuity spreads the income over 30 years, so only each year’s payment is taxed in that year. Depending on the jackpot size, the earliest annuity payments might not all land in the top bracket.
The annuity has its own trade-offs. Payments arrive on a fixed schedule, and most state lotteries do not allow you to sell or transfer future payments. For most large jackpots, the pure tax math favors the annuity, but the cash option remains far more popular because winners value immediate access to the money.
If You Plan to Share the Winnings
Handing cash to friends and family triggers federal gift tax rules. For 2026, you can give up to $19,000 per person per year without filing a gift tax return.4Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026 Anything above that counts against your lifetime gift and estate tax exemption, which is $15 million for 2026.7Internal Revenue Service. Whats New – Estate and Gift Tax You won’t actually owe gift tax until cumulative lifetime gifts pass that threshold, but you must file IRS Form 709 for any year you exceed $19,000 to a single recipient.
If a group intends to split a jackpot from the start — an office pool, say — everyone should sign a written agreement before the drawing and file IRS Form 5754 at the time of the claim. The lottery then issues separate W-2G forms to each member, and each person reports only their share.8Internal Revenue Service. About Form 5754, Statement by Persons Receiving Gambling Winnings This avoids the gift tax problem because the winnings were never yours alone.
Estate Tax on Annuity Payments
If you choose the annuity and die before the 30 years are up, remaining payments go to your estate or beneficiaries, and the IRS values that future stream for estate tax purposes using actuarial tables. The 2026 federal estate tax exemption is $15 million, and the top estate tax rate is 40%.7Internal Revenue Service. Whats New – Estate and Gift Tax A winner who dies with 20 years of payments remaining on a large jackpot could leave an estate where the present value of those payments alone exceeds the exemption. Beneficiaries then face income tax on each payment as it arrives and estate tax on the lump-sum valuation. This is one reason financial advisors sometimes steer older winners toward the cash option despite its heavier one-year tax bill.
