Maniax, it sounds like you are anticipating a tax audit and not that you are in the middle of one since your asking for 2012 betting slips. There are several loop holes for you to take advantage of. relax.
If you purchase betting slips make sure that they do not have a players card number. If the player used his card while placing the bet then that number will be on the ticket and it is useless for you.
The key is not to create red flags, 15k will not raise a red flag. When you file your taxes you have to itemize your deductions to include your gambling loss up to the amount of "reported wins", G-2W's. It sounds like your 15k win is from video poker or slots. If you won 15k on a stright sports bet you would not receive a W-2G, you would have received an 8300 form for cash transactions over 10k. In the future when you win more than 10k only take less than the 10k in cash and leave the excess in the cage to cash out another day, no 8300 form will be used.
You will not need suporting documentation when you file your taxes, but you will need it only if you are audited. Keep a daily gambling journal. Another easy way to do it yourself is to use an ATM machine inside a casino, either debit or credit card, keep those bank statements. Your you can cash personal checks at the casino cage. You have time to take care of this issue on your own.
darn the IRS.
