Powerball and Mega Millions are both multi-state lottery games operated by U.S. state lottery commissions. Federal and state tax treatment is identical. The real differences are in the matrix, the draw schedule, and the cash-value ratio on any given draw.

Why the tax treatment is identical
Both games are administered through state lottery commissions under state law, which means federal tax treatment follows the Internal Revenue Code's general rule for gambling winnings: ordinary income with 24% withholding at source. State tax is governed by the state that sold the ticket, and no state differentiates between Powerball and Mega Millions for tax purposes.
