S-Corp Election: When It Actually Makes Sense (and When It Doesn't)

The pitch for an S-corp election is simple: as a sole proprietor or single-member LLC, all of your net profit is subject to self-employment tax — 15.3% on top of your regular income tax. Elect S-corp status, pay yourself a 'reasonable salary,' and the profit left over after that salary avoids self-employment tax entirely, taken instead as a distribution.

What the pitch usually leaves out is that the salary you pay yourself has to run through actual payroll, with withholding, employer payroll tax filings, and often a payroll service. There's also a compliance cost — a separate S-corp tax return, and in many states, separate state-level filings. None of that is free, and none of it is optional once you've made the election.

So the math that actually matters isn't "self-employment tax versus zero" — it's the self-employment tax you'd save on the distribution portion versus the added payroll and compliance cost of running the election. Below a certain profit level, that added cost eats up most or all of the projected savings, and a straightforward LLC is simpler and just as cheap.

The other piece that trips people up is 'reasonable salary.' The IRS expects your S-corp salary to reflect what you'd actually pay someone else to do your job — not the lowest number you can get away with. Set it too low relative to your total profit, and you're building an audit risk into the structure you adopted specifically to save money.

There's no single profit number where an S-corp "kicks in" — it depends on your industry, your reasonable salary, your state, and what payroll and bookkeeping already cost you. That's the specific calculation we run before recommending an election either way, and it's also why the answer changes as your business grows: a structure that didn't make sense two years ago can make sense now, and vice versa.
