Formation of S-Corp for Gambling Trade
In a sole proprietorship AND an LLC, the expenses can still be deducted against the profits or losses from the operations. The IRS does not even require that a profit seeking activity be incorporated under its own entity, hence why this is also applicable in a sole proprietorship. From what you've said, there is no reason to use a more complicated and costly corporate structure at all. In comparison, a sole proprietorship and single-member LLC will be completely pass through entities to the IRS and all of their earnings go to you. With the LLC you have the option of letting the LLC's earnings remain with the entity itself, or you can just treat it as your own and pay individual income taxes on it. This has nothing to do specifically with a gambling business and is largely a red herring to your profit seeking motives. Gambling in casino games and lotteries already enjoy favorable tax treatment in some regards. Gambling in capital markets also enjoy a myriad of favorable tax laws. A business entity related to this purpose should be able to deduct costs related to this trade (and pass an audit more convincingly than not having formed an LLC and business bank account)
