At Commerce, I believe they ask for ID or a players card when you buy in or cash out $2000 or more, but they don't report it anywhere. Not 100% sure on the $2000 number but that's what I've noticed.

If your buyins or cashouts equal $10k or more in a given day, they will make you fill out a CTR form. Otherwise they won't bother you or report anything anywhere.

Tournaments are a different story. I'm not sure of their policy on that.
