This distinction applies to major Powerball jackpots generally, not just Castro’s prize.
Powerball’s official announcements routinely list both the annuity value and the cash value. For example, the official announcement for the $1.765 billion jackpot won in October 2023 also listed a cash value of $774.1 million before taxes.
That demonstrates that the gap between the headline jackpot and the cash option is a normal feature of the lottery’s payment system.
Federal Taxes Took a Major Share of the Cash Prize
After choosing the lump sum, Castro still had to deal with federal income taxes.
The cash payment was approximately $997.6 million before taxes.
Lottery winnings are taxable income under U.S. federal tax rules. The Internal Revenue Service requires gambling winnings, including lottery prizes, to be reported on a federal income tax return.
That means a winner of an enormous lottery prize cannot simply treat the full amount as tax-free money.
The amount of federal tax ultimately owed depends on the applicable tax rules, the winner’s circumstances, and the relevant tax year.
The federal tax system uses progressive income tax rates. Large taxable winnings can therefore result in a substantial tax bill.
What About California State Taxes?
California has a significant distinction in this story.
The California Franchise Tax Board states that California does not tax winnings from the California Lottery, including Powerball and Mega Millions prizes.
That means Castro’s California Lottery winnings were not subject to California state income tax.
But this does not mean the prize was tax-free.
Federal income taxes still applied.
The distinction is important because people sometimes assume that winning a lottery in a state without a state tax on lottery winnings means the winner keeps the entire prize.
That is not correct.
California’s rule removes the state income tax on qualifying California Lottery winnings. It does not remove federal income tax.
How the Estimated $628 Million Figure Was Reached
The commonly reported after-tax estimate of roughly $628 million is based on reducing the approximately $997.6 million cash option by federal taxes.
The calculation is a simplified estimate, not a substitute for a verified personal tax return.
The exact amount a winner keeps can depend on the tax year, the tax treatment of the prize, and other financial circumstances.
Still, the estimate makes the central point clear.
A cash prize of nearly $1 billion can become a substantially smaller amount after federal taxes.
Even after that reduction, the remaining fortune would still be enormous.
The difference between the headline prize and the estimated after-tax cash amount is why the story attracted so much attention.
A person could see the words “$2.04 billion lottery winner” and imagine that the winner had $2.04 billion available to spend.
The actual financial picture was different.
The Numbers Behind the Fortune
Let’s look at the journey from the headline jackpot to the estimated cash amount.
Step 1: The Advertised Jackpot
The Powerball jackpot was advertised at approximately $2.04 billion.
This was the annuity value of the prize.
It was the number displayed in headlines, lottery announcements, and public discussions.
Step 2: The Cash Option
Castro chose to receive the cash option.
That amount was approximately $997.6 million before taxes.
The difference between the annuity value and the cash value was approximately $1.0424 billion.
The cash option gave him access to the prize immediately rather than requiring him to receive payments over approximately three decades.
Step 3: Federal Taxes
Federal income tax then reduced the amount.
A commonly reported estimate placed the final after-tax amount at approximately $628 million.
That figure is useful for explaining the scale of the reduction, but it should be treated as an estimate rather than a confirmed personal financial statement from Castro.
Step 4: The Final Fortune
The estimated remaining amount was approximately $628 million.
That is still an extraordinary sum of money.
It is enough to change the financial circumstances of one family for generations, depending on how the money is managed and spent.
But it is not the same as $2.04 billion.
The difference between those two figures is the heart of the story.
Why the Cash Option Can Be Attractive
The decision between an annuity and a lump sum is a major financial choice.
The two options have different advantages and risks.
A lump-sum payment provides immediate control over the money.
A winner can use it for investments, property, charitable giving, family support, or other financial goals.
The winner also has control over how the money is managed rather than relying on a payment schedule over 30 years.
However, receiving a large amount of money immediately also creates responsibilities.
A person who suddenly receives hundreds of millions of dollars must consider taxes, investment management, security, family relationships, estate planning, and long-term financial decisions.
An annuity, by contrast, provides a structured stream of payments.
That structure may appeal to someone who prefers a predictable income over time.
It also means the winner does not receive the entire prize immediately.
Neither option changes the fact that the jackpot is advertised as an annuity value and that both choices are subject to taxes.
The right choice for any individual depends on personal circumstances and professional financial advice.
A Record That Put Powerball in the Spotlight
The $2.04 billion jackpot was notable not only because of its size but also because of how long the jackpot had grown.
Powerball is a multi-jurisdictional lottery game played across the United States and several U.S. territories.
Tickets cost $2 per play, and the jackpot is won by matching all five white balls and the red Powerball.
The odds of winning the Powerball jackpot are approximately 1 in 292.2 million.
That extremely low probability helps explain why the jackpot can grow through many drawings without a winner.
When no ticket matches all six numbers, the jackpot rolls over to the next drawing.
As more drawings pass, the advertised jackpot can become enormous.
The November 2022 drawing was the 41st drawing in the jackpot run before a winner was found.
That long run helped push the prize to the record-breaking $2.04 billion amount.
Is It Still the Largest U.S. Lottery Jackpot?
The $2.04 billion prize remains the largest U.S. lottery jackpot ever won by a single ticket according to Powerball’s official historical records.
