Cash flow is figured usually on a monthly factor.

It depends on several different factors.

Taxes are not cookie cutter and whether or not to elect an S-Corporation is based on a ton of different factors including your other sources of income, your retirement goals, your overall income levels and tolerance for the formalities of managing a corporation.If you've got a W2 at anything close to a decent wage, an S-Corp can cost you in taxes rather than save, so be very careful about handing this out (or accepting this) as blanket advice.Whether or not to use a different LLC every time is more of a legal question.
