Why this works

You stop paying self-employment tax on distributions.

As a sole proprietor, every dollar of profit gets hit with 15.3% self-employment tax on top of regular income tax. As an S Corp, you split your profit into a reasonable salary (which still owes payroll tax) and distributions (which don't).

The catch: the IRS requires your salary to be "reasonable" for the work you do. Set it too low and you invite an audit. We figure out the right number with you.
