Shhhh! If you win the Mega Millions jackpot, be quiet. Then, do this.

Lotto fever is rising again, with the Mega Millions jackpot surging after a win-less weekend, making it even more important that you know what to do if you beat the odds and win.

The top Mega Millions prize for Tuesday night's drawing is estimated at $875 million, the sixth-largest ever. Your odds of winning the Mega Millions are 1 in 302.6 million, but if you do, be prepared to keep your cool. As much as you might want to scream your win from the rooftops, the smartest thing is to shut your mouth and turn off your social media so you're not tempted to post about it, financial advisers say.

Claiming that much money likely will draw taxes, scammers, and friends and family members looking for financial help, they say.

“If you’re lucky enough to win the lottery, keep it quiet," says Rob Burnette, financial and investment adviser at Outlook Financial Center in Troy, Ohio. "Get organized and make a plan. Consider staying anonymous, if it’s a possibility.”

Why shouldn’t you tell everyone?

Scammers.

They may contact you to tell you you've won or if they know you've won, “the crooks usually try to get you to wire money for “taxes” or “fees,” or may try to get you to provide them with a bank account number, which they will then clean out," Mega Millions warns. "No real lottery tells winners to put up their own money in order to collect a prize they have already won."

Be suspicious of people who contact you out of the blue. No representative of Mega Millions would ever call, text, or e-mail anyone about winning a prize. In some states, you can remain anonymous if you win.

Steve Azoury, owner of Azoury Financial in Troy, Michigan, says he has advised many lottery winners, including a $181 million winner "who said ‘If I didn’t know you before, I don’t want to know you now.’”

If you can’t tell everyone you won, what can, or should, you do?

“Get a tax attorney and a tax accountant right off the bat and then a financial adviser,” says Azoury. “They’ll work hand in hand to figure out the plan.”

The plan will include which payout option to choose:

  • An annuity option makes an initial annual payment followed by 29 annual payments. Each payment is 5% larger than the previous one.

  • The cash option is a one-time, lump-sum payment equal to all the cash in the jackpot prize pool.  At Tuesday's drawing, it's $413.5 million.

The plan also should include a “fall guy,” Azoury says. “That’s the person or adviser who keeps you from giving loans to anybody, who tells people all the money’s tied up in investments, not available. We have nothing available to help you out, and we’re not interested in your project.”
