FWIW:
The $550 million jackpot is actually a $360 million jackpot. You can either take the $360 million or have the lottery purchase a 29-year annuity for you to get the advertised $550 million.
If you live in Kansas and take the lump sum, you will owe a 25 percent federal tax and 5 percent state tax, leaving you with about $252 million or one really nice limestone/lazy river around BSFS.
