[quote name='Vader582']Not sure if this has been bought up but since we should not be charged sales taxed on these in store, can he really be taxed otherwise? I was thinking the fact that these cards are part of a service and not a good may make a difference. Just a thought. *shrug*[/QUOTE]
It's not sales tax like you made a purchase. It's Income Tax like you received a paycheck from Microsoft. Any time you gain something of monetary value, the IRS classifies it as "INCOME" and adds that to your yearly income amount regardless of whether it was cash or not.
In fact, it doesn't even have to be contest winnings... Let's say you run up a $10,000 credit card bill, then stop making the payments and it goes to collections. Later, you strike a "settlement" deal with the company and they agree to settle the account for $2500. However, in the eyes of the IRS you just "made" $7500 worth of income because you "gained" that money that you wouldn't have otherwise, so as far as they're concerned, the fact that that debt was "forgiven" is no different than if some random guy on the street just gave you the other $7500, it still counts as taxable income.
So let's say the OP goes to file his federal income taxes this February, and his yearly income for 2010 was $30,000. Well, he now has an additional source of "income" in the amount of $1900, so now his yearly income is $31,900 and he'll have to pay taxes on that amount, which will eat into his refund since there was no withholding taken out of it at the time the money was "earned".
This is why when someone wins a slot machine jackpot, or a game show, or a drawing for a free car, they can choose whether to have the taxes taken out at the time, or they can wait and then it becomes due at the end of the year when they file their income taxes. It sucks to win a big prize if you can't afford to pay the taxes on it; you could end up in deep shit with the IRS...
EDIT: Also, to clarify the $600 misconception... ALL prize winnings are taxable income, even if they are just $1, however only prizes of $600 or more are
automatically reported to the IRS by the company granting the prize. For smaller amounts, you are supposed to voluntarily report it yourself,
technically. Just like how we all voluntarily report all of our online purchases at the end of the year so that we can pay the missing sales tax to our home states that we were supposed to have paid, right?
