“At what profit level does the expense of converting to an S-Corp make sense?”
The S-Corp profit threshold is one of the most-Googled small-business tax questions — and everyone quotes a different magic number.
Quick answer: On structure alone, Laura’s firm finds the S-Corp profit threshold sits somewhere around $40,000–$70,000 of net profit, and by about $70,000 it makes sense for almost everyone. But reasonable compensation moves the break-even: a consultant can justify a modest wage, a surgeon or dentist can’t. For some households it pays off at $10,000 of profit — so have the conversation around $50,000.
Looking only at the structure of an S-Corp — no other income, no special planning — Laura’s firm has calculated that it starts making sense somewhere around $40,000 to $70,000 of net profit. By about $70,000, almost everyone comes out ahead.
The savings come from the profit you take above a reasonable wage, which isn’t subject to self-employment or payroll tax. So your wage sets your break-even. A consultant or service provider can often justify a relatively modest salary, leaving more profit to flow out as distributions. A surgeon, anesthesiologist or dentist can’t credibly claim a $50,000 salary — their reasonable compensation is much higher, so the profit level where the S-Corp pays off moves up.
The number bends the other way too. Depending on your spouse’s income and how the whole return is built, an S-Corp can make sense at $10,000 of profit — and for some people, even before the business is profitable. The rule of thumb is a starting point, not the answer.
For a new LLC, a good middle marker is about $50,000 of profit — that’s when to sit down and ask whether the S-Corp makes sense for you. Factor in the real costs (running payroll, a separate business return, state fees) and your goals: are you building to sell, hiring, or growing? Sometimes it makes sense from day one; often it doesn’t yet.

As a rule of thumb, somewhere between $40,000 and $70,000 of net profit, with almost everyone benefiting by about $70,000 — but your wage, household income and goals can move that number.
Their reasonable compensation is much higher, so less profit is left to take as distributions, which is where the savings come from.
Payroll processing, a separate business tax return, and state fees or taxes, which vary by state.
Sometimes, depending on your spouse’s income and how your full return is structured. That’s a case-by-case calculation.
