A Mega Millions jackpot winner usually keeps somewhere between 24 and 29 percent of the advertised prize after taxes, and often less in states with high income tax rates. The billboard number is the annuity total, not cash on hand, so the shrinkage starts before the IRS ever gets involved. Looking at Mega Millions after taxes means stacking three separate cuts: the cash-option discount, federal income tax at the top bracket, and state (sometimes city) tax where you claim.
The Cash Option Shrinks the Headline First
Every jackpot winner picks between a lump sum, called the cash option, and an annuity paid in 30 installments. The advertised jackpot reflects the annuity total, not the money sitting in the prize pool today.1Mega Millions. Difference Between Cash Value and Annuity
The cash option is typically around 46 percent of the advertised figure. A $500 million advertised jackpot yields a cash payout of roughly $230 million before any taxes.1Mega Millions. Difference Between Cash Value and Annuity The discount exists because the lottery would otherwise invest the pool over 29 years to reach the full advertised amount. Take the money now and you forfeit that growth.
The annuity pays one immediate installment followed by 29 annual payments, each five percent larger than the last, meant to offset inflation over the payout period.1Mega Millions. Difference Between Cash Value and Annuity
Federal Withholding vs. What You Actually Owe
Federal law requires the lottery to withhold 24 percent for federal income tax on any prize above $5,000.2Office of the Law Revision Counsel. 26 USC 3402 – Income Tax Collected at Source That money goes to the IRS as a prepayment. It is not the final bill.
A jackpot pushes nearly all of your taxable income into the top federal bracket, which for 2026 is 37 percent on income above $640,600 for single filers and $768,700 for married couples filing jointly.3Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026 Because almost every dollar of a nine-figure prize sits in that bracket, your effective federal rate lands very close to 37 percent.
That leaves roughly 13 percent of the gross prize still owed after the initial withholding. On a $230 million cash option, the shortfall is about $30 million. Set it aside on day one or you will be scrambling at tax time.
Lottery winnings are not subject to Social Security or Medicare taxes. Those apply to wages and self-employment earnings, not gambling proceeds, unless you gamble as a trade or business.4Internal Revenue Service. Publication 525 – Taxable and Nontaxable Income
Estimated Payments Close the Gap
The IRS expects you to cover the shortfall through quarterly estimated tax payments, not by waiting until you file. Payments are due April 15, June 15, September 15, and January 15 of the following year, and the payment for the quarter in which you claimed the prize is the one that matters.5Internal Revenue Service. Individuals 2 – Estimated Tax Claim in August, and a payment covering the shortfall is due by September 15.
Missing that deadline triggers underpayment penalties and interest. The IRS notes specifically that gambling winners may need estimated payments on income beyond what was withheld.6Internal Revenue Service. Topic No. 419, Gambling Income and Losses
State and Local Taxes Vary Widely
Where you claim the ticket determines the next cut. Eight states with lotteries do not tax lottery winnings at all: California, Florida, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming. Five more states do not participate in Mega Millions at all: Alaska, Alabama, Hawaii, Nevada, and Utah.
In states that do tax winnings, rates run from about 3 percent to nearly 11 percent. New York sits near the top at 10.9 percent; North Dakota is near the bottom around 3 percent. Some cities pile on their own income tax. New York City withholds an additional 3.876 percent, so a resident there faces a combined state and city bite of roughly 14.8 percent before federal taxes.
Bought the ticket while traveling? The state where you purchased it may still tax the prize as income sourced to that state, even if you live elsewhere. Your home state generally credits taxes paid to another state, so you are not double-taxed on the same dollars, but you will file returns in both.
What You Net on a $500 Million Jackpot
The numbers below use the cash option, which is how roughly 70 percent of jackpot winners collect.
Cash Option in a No-Tax State
- Advertised jackpot: $500,000,000
- Cash option (about 46%): $230,000,000
- Federal withholding (24%): −$55,200,000
- Additional federal tax (about 13%): −$29,900,000
- State tax: $0
- Approximate net: $144,900,000
A Florida or Texas winner keeps roughly $145 million of a $500 million advertised prize, about 29 percent of the billboard number.
Cash Option in a High-Tax State
- Advertised jackpot: $500,000,000
- Cash option (about 46%): $230,000,000
- Federal withholding (24%): −$55,200,000
- Additional federal tax (about 13%): −$29,900,000
- State tax (about 10.9%): −$25,070,000
- Approximate net: $119,830,000
A high-tax-state winner nets around $120 million, roughly 24 percent of the advertised jackpot. Add a city tax like New York City’s and the total can drop below $110 million.
Annuity Payments Don’t Escape Tax
Taking the annuity spreads the tax bill out; it does not avoid it. Each of the 30 annual payments is ordinary income in the year received, subject to federal and state tax at whatever rates apply that year.4Internal Revenue Service. Publication 525 – Taxable and Nontaxable Income The lottery withholds 24 percent from every payment, and you owe the rest each year.
The annuity’s advantage is that it locks in the full advertised amount and pays out predictable, growing income for three decades. The cost is loss of control over the principal and exposure to whatever federal and state rates exist in each future year.
Gifts and Group Pools Change What You Keep
Handing money to family will not sting immediately, but it does have to be tracked. For 2026, you can give up to $19,000 per recipient per year without filing a gift tax return, and married couples can combine exclusions for $38,000 per recipient. Gifts above that count against a lifetime exemption of $15,000,000 per person for 2026.3Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026 Any gift above $19,000 to a single person in one year requires IRS Form 709 by April 15 of the following year, even if no tax is owed.7Internal Revenue Service. Instructions for Form 709 Giving $5 million each to four siblings burns $20 million of that lifetime exemption in a single year, so structured gifting worked out with an estate attorney before checks go out matters.
If the ticket came from a workplace or friend pool, each member’s share is reported separately. The person claiming the prize files IRS Form 5754 listing every pool member’s name, taxpayer ID, and share, and the lottery issues each member a separate Form W-2G.8Internal Revenue Service. Form 5754 – Statement by Person(s) Receiving Gambling Winnings Skip Form 5754 and the IRS treats the whole jackpot as income to the one claimant, who then faces gift tax exposure on every share distributed afterward. A signed pool agreement before the drawing keeps the paperwork clean.
