Powerball winnings in California and Pennsylvania are subject to Federal income tax only. There is no state income tax in Florida, South Dakota, Texas, Washington and Wyoming, and only on interest and dividends in Tennessee and New Hampshire. Winnings from tickets purchased outside of one's home state may be subject to the income tax laws of both states (with possible credit based on the two jurisdictions.)
In the United States, lotteries are run by 47 jurisdictions: 44 states plus the District of Columbia, Puerto Rico, and the U.S. Virgin Islands. Lotteries are subject to the laws of and operated independently by each jurisdiction, and there is no national lottery organization. However, consortiums of state lotteries jointly organize games spanning larger geographical footprints, which in turn, carry larger jackpots. Two major lottery games, Mega Millions and Powerball, are both offered in nearly all jurisdictions that operate lotteries, and serve as de facto national lotteries.

A Powerball jackpot winner may choose to receive their prize in 30 payments over 29 years or a lump-sum payment. The cash value option, in general, is the amount of money required to be in the jackpot prize pool, on the day of the drawing, to fund the estimated jackpot annuity prize. The advertised jackpot annuity and cash value are estimates until ticket sales are final, and for the annuity, until the Multi-State Lottery Association takes bids on the purchase of securities. 

The odds of winning the Mega Millions jackpot are 1 in 302.6 million, making them the highest odds of any other state or multi-state lottery game ever played in the United States. However, this means the jackpot can grow to surpass the billion-dollar mark with relative ease. The overall odds of winning any prize are 1 in 24, which is slightly better than that of Powerball, which are 1 in 24.87.

The original version of Lotto America (stylized as Lotto*America) was a $1-per-play, pick-7-of-40 game, rather than the pick-6 games that had become wildly popular in U.S. lotteries. Matching four numbers won a fixed prize of $5; matching at least five won a parimutuel prize. Matching all seven won the jackpot, whose odds were roughly 1 in 18 million, at the time the longest odds of a U.S. lottery game. The top prize was a 20-year annuity; there was never a cash option, even though a few games did offer one when L*A ended.
Powerball numbers are drawn from two sets of numbers, so the odds of winning a prize are calculated by combining the odds for both sets of numbers for all prize levels. The odds for matching just the Powerball are calculated by combining the odds of selecting the Powerball and the odds of not selecting any of the five numbers from the first set of numbers drawn.
Based on statistical projections, the average jackpot win increased from $95 million to $141 million. Over 3.5 million additional prizes were expected to be won yearly due to the change in probability. The starting jackpot increased to $20 million, with minimum rollovers of $5 million. The jackpot contribution increased from 30.3% to 32.5% of total sales. The Power Play option was modified; second prize, usually $200,000, was given an automatic 5x multiplier, making the 5+0 prize $1 million cash. The bonus second prize if the jackpot exceeded its previous record by $25 million, triggered only twice, was eliminated with the 2012 format change.
Ask for the All Star Bonus with your Lotto America purchase! For an extra $1 All Star Bonus purchase you could increase your prize amount (except the jackpot) by 2, 3, 4 or 5. If you match 5 white ball numbers and have purchased the All Star Bonus, you will have multiplied your $20,000 prize to as much as $100,000! The prize payout does not increase if you match 5 and the Star Ball; in that case you win the jackpot!
The October 28, 2017 Mega Millions' format change resulted in the game's first price increase: plays are $2 each ($3 with the Megaplier; up from $1 and $2 respectively); as part of the format change, the "Just the Jackpot" option was introduced to seven of the game's members. The new option is two plays for $3; only the jackpot can be won (or shared) on this wager.[3][4][5]
When a player wins the Lotto America jackpot, the winner may choose to receive the prize in annuity payments or may elect to take a lump-sum payment. A player has 60 days from the date they claim their prize to choose the "cash" option or the "annuity" option. If the player selects the "cash" option, the prize will be a single cash payment equal to the amount available to the lottery for the jackpot prize pool. The "cash" prize is estimated to be approximately one-half of the estimated jackpot, depending on current interest rates. If the player chooses an annuity, it will be paid in 30 payments over 29 years, and the annual payment will be increased by a rate as determined by lottery officials. If the cost to purchase the annuity is less than $250,000, the lottery may elect to pay the prize as "cash."
On May 18, 2013, the world's largest one-ticket jackpot, an annuity of approximately $590.5 million ($620 million today), was won by a Powerball ticket sold in Zephyrhills, Florida.[33] On June 5, Florida Lottery officials announced the winner: Gloria C. MacKenzie, 84, who purchased the "quick pick" ticket at a Publix supermarket.[34] MacKenzie chose the cash option of approximately $370.8 million, before Federal withholding; Florida does not have a state income tax.[34]

Even though some scratch cards costing as much as $50 in Texas and $30 in Massachusetts, state lotteries are exempt from Federal Trade Commission “truth in advertising laws” The Federal Communications Commission prohibits the broadcast of lottery advertisements, but has exemptions for lotteries “conducted by a state acting under the authority of state law. Hence, TV commercials like “The Possibilities are Endless.” (Lotteries raise over $70 billion a year, according to the North American Association of State and Provincial Lotteries. Profits from the Powerball are used to fund public projects approved by state legislatures.)
Jump up ^ Lotto, Lucy (June 30, 2011). "Powerball Lottery Changes for 2012". WorldLottery.net. Archived from the original on August 23, 2013. Retrieved September 4, 2013. The first and biggest change to the Powerball Lottery is the introduction of the $40 million base jackpot. Now, when the Powerball Lottery jackpot is reset after a win it will start at $40 million, tempting even more players in for those early draws. Another promise, that is sure to be popular with lottery players, is the introduction of more prizes. From January, Powerball players will have even better odds of winning a prize worth at least $1 million, and it’s that fact that may soften the third and biggest ever change. From January 15, 2012, Powerball Lottery tickets are doubling in price, in what is the biggest change to the Powerball Lottery draw since its launch in 1994.
The US Powerball is a standard lottery draw game based and operated from the golden State of California. The US Powerball has been making millionaires and multi-millionaires since its first drawing way back in 1992. With over 25 years of experience in the lottery industry, the Powerball, along with many other State lotteries, has broken through the final glass ceiling and transformed itself from an interstate lottery into a truly international lottery of global reach.
