How it works
As a sole owner, self employment tax is about 15.3 percent of 92.35 percent of profit (up to the Social Security cap). With an S corp you pay 15.3 percent of your salary only. The difference minus added costs is the saving.
Worked example
On 150,000 of profit and a 70,000 salary, savings are roughly 10,500 before extra costs and about 8,000 after them.
Good to know
This ignores state taxes, the qualified business income deduction and retirement plan effects. These are planning estimates, not tax or legal advice. Rules and limits change, so confirm at irs.gov, uscis.gov, ssa.gov or with a professional.
