If there's a jackpot winner in the next Mega Millions drawing, someone is going to have a very, very happy New Year. The top prize has climbed to $415 million for Tuesday night's drawing. The last time someone hit the jackpot was Oct. 23, when a single ticket sold in South Carolina nabbed a whopping $1.537 billion. The owner of that valuable slip of paper, who has until late April claim the prize, has not yet come forward. Yet even when the money is claimed, the world might never know who won — winners are allowed to remain anonymous in the Palmetto State.

However, the next prizewinner might not easily shield their identity. Only a handful of states allow you to claim lottery wins anonymously. In some states, you might be able to collect your windfall via a trust or other legal entity to keep your name out of the public eye. In others, it's unavoidable. While the current $415 million top prize is less than a third of that unclaimed $1.5 billion windfall, it's nothing to sneeze at. Even after paying taxes, the winner's take would put them among the wealthier people in the country. The upfront cash amount — the option most winners go with — is $248.8 million. The federal government will withhold 24 percent for taxes, reducing it by about $59.7 million to $189.1 million. And unless you live where there's no state income tax or lottery wins are untaxed, you can face state withholding that can reach 8.82 percent, depending on where you live. You can also expect to owe more at tax time. If you manage to beat the astronomical odds against winning the Mega Millions — your chance is 1 in 302 million — here are some expert tips to try protecting your privacy.

Get off the Internet

If you can't remain anonymous when you collect your winnings, shut down your social media accounts in advance, said Jason Kurland, a partner at Rivkin Radler, a law firm in Uniondale, New York. "The media will try to find as many pictures of a winner as possible, and social media is the first place to look," said Kurland, who specializes in helping lottery winners. "You also want to make sure there's as little personal information out there like your phone number or address." In other words, don't make it easy for scammers and snoopers to track you down. If you have a landline phone, make sure it's unlisted before you head to lottery headquarters.

Plan an escape

Kurland said he advises his big jackpot winners to skip town immediately after claiming their prize. "Just being out of town for a few days can help," Kurland said. "In this 24-hour news cycle, the interest in a winner will hopefully disappear after a few days. If you can avoid being around for a week, you might be able to escape the initial exposure."
