There are people claiming to be so-called experts on many other forums, that are talking about table games proof of winnings and filling out 1099 and W2Gs, etc. I can't even believe that they would bring this topic up because they've done no research, they have no actual experience and they are preaching with no knowledge whatsoever and obviously no experience whatsoever. Yet they come off as well versed and experienced long term players regarding table game payouts and the reporting rules and regulations.

First of all table game wins do not and never did require a 1099 or W-2 G, never ever, as so many think they do just because slot machine wins do require them.  Table games do not even if you won $100,000.00 in one shoe and want to cash it out.  There is no reporting to the government or the IRS how much you won or lost in table games, unless you did a cash transaction of $10,000 or more.

I might throw in except for poker tournaments, not from regular day-to-day poker table play. And also it only applies to a poker tournament were more than $5,000.00 was won, after the buy in or wagered amount is deducted.

The government has IRS Form #8300, that is filled out by the casino when you buy in with an excess of $10,000.00 within the casinos 24 hour day. It is also fills out and files the same form, if you are cashing out $10,000.00 or greater within the 24 hour casino day.  Does not matter if the cash you receive amounts to winnings or if you are still in the negative.  And this can be in segments, it doesn't have to be at one time during the 24 hour casino day.

Also with the combination of buying in and cashing out. For example, you can buy in for $3,000.00, cash out $4,000.00, and buying once again with $3,100.00 within the 24 hour casino day and you will generate yourself having the form filled out by the casino.

The first time it is filled out they will ask you for your ID and Social Security number and personal information, if they don't already have it.  Every other time it is automatically done without any knowledge whatsoever by the pit personnel, cage personnel and yourself.

There are also casino discretionary limits anywhere starting from $3,000.00-$5,000.00 that also applies. The biggest deciding factor will be if you are a known player, ID & Social Security, etc. on file, with some kind of history at the casino. Otherwise they can and probably will generate one, filing it for less than $10,000.00 within their own discretion. That form is entitled an SAR Form. 

Also on a sidenote as far as casinos asking for ID when cashing out under $10,000.00 and a government form will not be generated, that is entirely at their own discretion as well within their set rules and regulations as to when they will ask for it at the cage when cashing out. Lots of smaller casinos do this after the $1,000.00/$2,000.00 mark especially if they don't recognize the player. 

As far as jackpots at table games, it has to be a 300:1 or greater payout to the wagered amount for any form to be filed with the government.

Those are the facts and I have to give a chuckle at the so called experts on the other forums claiming falsehoods and swearing by them.
