If you win the $630 million Mega Millions jackpot, here’s how much would go to taxes

So you didn’t win the $555 million Mega Millions jackpot Tuesday night.
The glass half-full view? Phew! You dodged a huge tax bill. 

Of course, you get another shot in the next drawing to land a windfall — and then give a boatload of it to Uncle Sam. The national lottery game’s top prize has rolled even further past the half-billion-dollar mark and is worth an estimated $630 million for Friday night’s pull.

If won at that amount, it would mark Mega Millions’ fifth-largest prize ever, but does not crack the top 10 biggest jackpots of all time.

And, it would come with a sizable tax bill. Whether the prize is taken as an annuity of 30 payments over 29 years or as an immediate, reduced cash lump sum, taxes end up taking a big bite out of any winnings.
