Supplying you SSN for a CTR has nothing to do with taxes. If you have a taxable event at the casino, you will get a tax form. A CTR for a $200k cash out will not alone trigger any necessary action. BTW be careful, just because you have corresponding losses of $250K, you still may have to prove this. And they filing may certainly be more complicated than just claiming the offset.

Also note a CTR can be required for buying chips not only cash outs. If you buy $10K of chips with cash, they should file a CTR. In fact if you buy $5000 and later bust and rebuy another $5000, they are supposed to get the info to file a CTR. But just like the CTR for a cash out does not imply income, a CTR for a cash purchase is not evidence for a deduction or loss.

That's what I don't feel like dealing with, proving my losses if it comes down to it. Without my SSN I should most likely never have to deal with that. I really don't think it would be an issue to provide my SSN but it's more a "better safe than sorry" situation. I'd just hate to be in a crappy situation because I provided it, but it sounds like I could be in an even worse one if I don't (getting banned). They're already doing an investigation. I told lottery go ahead it's fine, when I play, what time I was there that night, etc. Since I have nothing to hide. But now I'm worried the casino might just say we don't feel like dealing with you, get out and don't come back.

If "they" are "doing an investigation" you are far more likely to also see IRS get involved as a result.

We've now switched to a completely different topic, but on the subject of taxes owed:

* You owe them whether or not the casino gives you paperwork
* If you're a recreational gambler, you can't just net your wins and losses
* You must declare your wins (per session), and can't even deduct your losses unless you itemize, which most people don't do especially in the last few years since they increased the standard deduction
* You should contact a tax attorney about it rather than listen to internet people like us if you have any questions

Anyway, you do you. You've gotten all the good advice there is to give on these topics.

Whether you owe taxes on gambling wins, need to prove this, etc have NOTHING to do with filing a CTR and providing your SSN.

CTRs, while they can be accessed by IRS, are not normally provided to IRS. If IRS audits you, they might pull any CTRs filed in your SSN. But giving your SSN for a CTR will not trigger anything at IRS.

Giving your SSN, again it is required, for certain wins in the casino, will go to the IRS along with the proper paperwork. Liver Poker cash play wins will not trigger this. A BBJP or similar large enough "win", will trigger IRS paperwork including a requirement to provide SSN. For those wins, if casino doesn't already have your SSN or you don't provide it when asked, you simply will not get paid. Period. The casino has zero say in these things. But for tax advice seek the advice of a lawyer and/or a accountant.

I am not sure who "lottery" is or who is doing an investigation or what they are investigating. The thing to remember is casinos are monitored by the feds particularly around potential money laundering and the regs the casino must follow. This is why nearly all non-reservation casinos no longer allow cash to play. (GNLV is the only exception I know of but I am sure there area few others.) The feds literally contacted the casinos several years ago and warned they would be watched closely and needed to implement AML processes concerning cash in play.

So while the casino loves to have you in there and 'giving them money' (not much if a live poker only player), they care much more about their license and any fines. If you become a squeaky wheel w.r.t. these issues, they will simply choose to fire your as a customer. If you happen to be a mega whale, they probably will have a discussion to inform you of the risk. But if you are like most of us, they will simply ask you to leave and never return.

It is nothing against you per se. They just do not want to run the risk of the feds coming down on them for something you did or did not do.

So yes, you have a chance of being kicked out. I do not know any of your fact details or the casino involved. IANAL, but imo the best thing to do is do what the casino asks, when they ask, w/o making a fuss. At least where financial transactions are concerned. "Firing" customers is becoming much more a thing. But also remember, the casino is supposed to be held to the same standards for safeguarding the infomation they collect from you.

Just make up a fake one

Another good way to get banned, a SAR, an investigation and potentially prosecuted. Only now it might be multiple federal charges.

You do realize they take more than SSN. Such as verifying name and address.

But feel free to screw around with the feds. Though I do hear they have developed a recent passion for pursuing id theft cases.

A SSN is 9 digits, so if you're gonna write down a random one (although it's not advised) at least make sure it's 9 digits and not someone's phone number from the 90's (if they're over 40 it would be a dead give away).

Nice try, but I know for a fact that number is Jenny's.

Be careful who you give your number to. They might put it in a song then everyone will know it.
