One lucky winner in Florida is poised to take home the $450 million Mega Millions jackpot.

The winning numbers for Friday's drawing were 28, 30, 39, 59 and 70, plus Mega Ball 10.

The $450 million jackpot ranks as the fourth largest in the game's history, and the second largest awarded to a single ticket. At least for now, it's also the 10th largest jackpot in U.S. history.

Of course, that lucky winner won't walk away with the full amount. If the winner opts to take the $281.2 million lump sum, lottery site USAMega.com estimates the federal tax withholding would be $70.3 million. That is just the amount withheld up front; the final tax burden is likely to be even higher.

Yet the winner has an extra bit of luck: Florida does not have a state income tax. Compared to other states' rates, that's a savings of up to $24.8 million in taxes withheld up front. (Plus, the winner may benefit from tax law changes, including a reduction in the top tax rate from 39.6 percent to 37 percent.)
