Mega Millions jackpot swells to $227 million. What to do first if you win.

With no one hitting the latest Mega Millions jackpot drawing, the prize has climbed to $227 million.

One of the big decisions you’ll have to make if you win is whether to take the lump sum of $134 million or spread the winnings over several decades. For the cash option, the 25 percent federal tax withholding of $33.5 million would reduce the amount to $100.5 million. You also likely will owe more to Uncle Sam at tax time.

On top of that, there will be state taxes on your windfall unless you live where lottery wins are untaxed. In states that do take a piece, the range is from a high of 8.82 percent in New York to a low of 2.9 percent in North Dakota, according to lottery site USAMega.com.

The important thing is to avoid becoming a lottery winner who unintentionally fritters away the new wealth.

“The main reason that happens is there’s a failure to develop a plan for careful and thoughtful management of the money,” Shagawat said.

Here are some tips for the winner.

Experts recommend sharing your win with no one but your family or closest circle of friends. News has a way of spreading quickly, and you don’t want to unwittingly become a target for people seeking hand-outs, loans or other access to your sudden wealth.

Maintaining your privacy is easier if you don’t have to go public with your win. Find out whether you can claim your prize anonymously in the state where you purchased your ticket. Some states make it easy to remain anonymous, while others require a bit more planning. And in some states, it’s impossible.

Also, keep the ticket close. The general advice is to sign the winning ticket and make several copies. The idea is that if you somehow are separated from the ticket, your signature should help ensure you get the prize.

However, that also could prove problematic if you are allowed to claim the prize via a trust to protect your identity. This makes it important to consult with a trusted advisor before doing much of anything.

Experts recommend assembling a team of experienced professionals, including an accountant, a financial advisor and an attorney (this should be your first call).

One of those pros should be your gatekeeper for all future requests for money, whether from family, friends or others.

“Some people give away too much money to family and friends, and they do it to a point that it damages their own life goals,” Shagawat said. “When the gifting starts, it’s difficult to stop.”

The more people who know about your newfound wealth, the greater the chance you’ll be approached. Having a gatekeeper to screen all requests and fend off outstretched palms can ease any pressure or guilt that could lead you to making foolish financial decisions.

“I tell clients to tell all of their friends and relatives that they can’t make any donations, gifts or investments without running it by me as their advisor,” said Jason Kurland, a partner at Rivkin Radler, a law firm in Uniondale, New York.

Depending on where you live, you have about six months to a year to claim your prize, so you don’t need to be in a rush.

“Give yourself time and space to process it,” Shagawat said.

Before planning to spend a dime, think about what this sudden wealth means — financially and otherwise.

While at first you might dream only of a new house, new car or extended vacation, winners often realize it’s a chance to consider their legacy and think about any societal contributions they want to make. Some even set up their own charitable organizations.
