If you're an officer in an S-Corp, you're required to pay yourself a "market rate" salary for payroll tax purposes, and cannot legally use the salary/draw distinction as a tax avoidance strategy. If you're not paying yourself a salary, the IRS gets very annoyed.

If you're a sole proprietor, the tax impact should be equivalent whether you choose to take draws or salary:

> Sole proprietors and members of partnerships are free to pay themselves — or otherwise take the profits out of their businesses — whenever they’d like. Payroll withholdings do not apply, but each individual essentially pays the equivalent on his or her reported income at tax time.
