I kinda wish it wasn't a hoax. It would be as close as we'd likely ever get to the "pay your taxes the day before election day" thing. The average American needs a good slap in the face to wake up to what the government is doing with our money.
When people have taxes deducted from their paycheck before they ever see the money, to most of them, it's like that money was never there. They consider their tax refund to be like getting a bonus at work. Were they to get their tax return showing they were going to get a check for "X" dollars, but not for six months, it might help them make the connection and maybe rile folks up a bit.
