DES PLAINES, Ill. (NewsNation) — The Illinois winner of July’s Mega Millions $1.34 billion lottery drawing has fewer than 10 days to decide whether they would like to be paid annually or all at once, according to state lottery officials.

Waiting to claim a lottery fortune is common — most legal and financial experts advise getting your ducks in a row before stepping forward. 

But the deadline for the July 29 winner’s decision is rapidly approaching. According to the Illinois Lottery’s Winner’s Handbook, if a decision is not made, the winner will automatically be paid annually.

According to NBC Chicago, the winner would be paid annually over 29 years. If they opt for a one-time cash payout, that would be about $780.5 million.

“If you are a winner who receives annuity payments, you receive the interest earned on the bonds purchased by the Lottery for the payment of the prize up [to] the prize amount,” the handbook dictates.

The winning ticket was sold at a gas station in Des Plaines, a suburb of Chicago. It was the second-largest jackpot in Mega Millions history. The largest was in South Carolina in 2018 when a single ticket fetched $1.53 billion.
