If you win a Sweepstakes or Lottery Prize on a game show, the winnings are taxable only if you win over $10,000. Make sure you receive document about taxes from the entity that awarded you the cash prize, and they’ll also send a copy to the IRS.
Merchandise you win is taxable but is fully reimbursable by Publishers Clearing House. Taxes and fees are paid depending on where you live and how much you win. You’ll need to pay federal taxes on the winnings.
