It’s my understanding that a corporation is its own entity and is taxed in that way, but there are many permutations of “corporation.” With an S-corp, the directors have to pay themselves a “reasonable” salary (determined at whim by the IRS if whatever you come up with is not regarded as “reasonable”) and then can draw “dividends” from the rest of the revenue. The way it has been explained to me, these dividends are not regarded as income to be counted against Social Security benefits when you are under “full retirement” age, and that is the sole benefit of the arrangement for me.

What circumstances allow you to buy supplies wholesale, I do not know.

Elaborate on the tax advantages. My husband and I have recently discussed this very thing.
