After no one won Tuesday night's Mega Millions drawing, the prize increased to $940 million, making it the sixth- largest in US history.
The Mega Millions winner can choose to receive the cash in 30 installments of an estimated $940 million over the next 29 years.
If the winner chooses the lump sum, they will have to pay federal tax on it.
The winner would have to pay income tax at the top federal marginal rate of 37% unless they manage to claim large deductions through things like charitable donations, which will leave them with $231.46 million before state taxes and other deductions.
If the winner chooses installments, they'll get an immediate $32.33 million before taxes, followed by the same amount every year for 29 years.
The installments would total around $7.5 million each year, followed by a federal income tax of $8.7 million, leaving them with around 15 million before state taxes, assuming they don't claim any deductions.
Different tax laws will affect the amount of money the winner gets to take home. Texas, Florida and California don't tax lottery winnings at all. Texas, Florida, Washington and Nevada don't have income taxes.
