Ask the Taxman- Will I get a 1099 for my Blackjack winnings next year?
Source: Quora
Answer:
The casino does not issue a W2-G/1099 on table games such as poker or blackjack like they do for slots. This does mean the income is not taxable. Remember that purposely not reporting taxable income is a felony, and if the IRS comes to you, you will be in a bad position. Also know that the IRS monitors searchable public forums like Quora
