For single person LLC (as the OP said) it doesn’t make any difference - they’re paying all taxes on the entire amount and then just deducting business expenses. IOW their business account does not require any special treatment. For corps (including S corp) there’s often this temptation for the founders to pay themselves the bare minimum and skirt some of the taxes (social security for example). I was pointing out that this is a good way to draw unwanted attention.
