With a 25% tax rate and car value of $28,500; to make it a tax-free gift Oprah should've paid an additional $9,500.
There’s a great YouTube view about exactly this by Stand Up Maths if you want to go down a rabbit hole.
Correct. Prize winnings are taxed at your ordinary income tax rate. The gift tax applies to gifts, not prize winnings, and even then, the giver pays it, if applicable.
They still take place. I suspect the buildings have moved with the (architectural) times.
Is it simply counted on top of (added to) your existing income, and therefore progressive?
If I'm unemployed, with no income at all, would I pay very little to no tax on such a gift? Or gifts are a special case with a separate rate?
I don't think it's a gift tax, but ordinary income tax. A coworker won a living room sofa set on a game show, and the staff were waiting with a 1099 for her as soon as she stepped off the stage. The IRS says you need to pay tax based on the fair market value, but the shows will list the prize at it's full retail price.
So if you should happen to (and you won't) win the Acura, you'll owe 25% or more on it. Plus any state income tax. I'm not sure when the IRS actually wants their money, but a safe assumption would be "soon". Perhaps by the next quarterly estimated-tax date.
