New Hampshire: 10% tax on $600+ winnings: even from out of State!

[XIIPointStables]

Not a good day for handicappers in New Hampshire.

From the Union Leader...

Gambling winnings of more than $600 will be taxed at 10 percent. It applies to all who gamble here, and all state residents no matter where they gamble

Is this done in other States? How the heck would they collect it?

How will they track down my Mohegan Sun or Saratoga wins. And what if it costs me $80 to hit a $600 tri?

Seems pretty un-American to me. I need to move.

Edits: If I'm reading it correctly, it's basically an extra 10% tax on any W2-G you are issued...does that make sense?

Also, I added some text of the bill here and attached.
