Miguel nets $50,000 a year freelancing as a graphic designer in California. A generic online guide put $50,000 in a table labeled "Negative" for S-Corp election, next to a vague range of compliance costs — true as far as it goes, but it never says why, and it never counts the deduction Miguel would actually lose. Running his real numbers: S-Corp election would cost him $329 a year, not save him anything.
What the Generic Rule of Thumb Gets Right, and Skips
Most guides to this decision compare gross payroll-tax savings against a rough compliance-cost range and stop there. That comparison is real, but it leaves out a cost that applies to every S-Corp election regardless of state or CPA fees: electing S-Corp status converts part of your profit into W-2 salary, and salary is not Qualified Business Income. The 20% QBI deduction that applies to a sole proprietor's profit doesn't apply to that slice once it becomes a paycheck. For Miguel, that's the difference between a vague "probably negative" and an exact $329 loss with a specific cause.
Step 1: The Payroll Tax Comparison
As a sole proprietor, self-employment tax applies to 92.35% of Miguel's $50,000 net profit:
$50,000 × 92.35% = $46,175, taxed at 15.3% = $7,065 in self-employment tax.
If Miguel elected S-Corp status and paid himself a $25,000 salary (50% of net income — comfortably inside the "safe" range this tool flags, well above the 38% line where the IRS starts looking harder), combined payroll tax applies only to that $25,000:
$25,000 × 15.3% = $3,825 in payroll tax.
Gross payroll-tax saving: $7,065 − $3,825 = $3,240. This is the number a payroll-tax-only comparison would call his "S-Corp savings."
Step 2: What Running an S-Corp Actually Costs Miguel
- Payroll software to run the $25,000 salary through payroll: $600/year
- CPA premium for Form 1120-S, since Miguel doesn't have an existing CPA relationship to build on: $1,800/year
- California's S-Corp franchise tax — 1.5% of profit, with an $800 minimum that binds at Miguel's income: $800/year
Total compliance cost: $3,200/year — already most of the $3,240 gross saving, before the QBI loss is even counted.
Step 3: The Deduction Most Rule-of-Thumb Tables Never Mention
This is the piece the generic "Negative" label skips entirely. As a sole proprietor, all of Miguel's profit (after deducting half his SE tax) is QBI-eligible, giving him a 20% deduction on that base. As an S-Corp, only his $25,000 distribution is QBI-eligible — his salary isn't. That shrinks his QBI deduction by $1,456, which pushes $369 more of his income into taxable territory at his marginal rate.
The Real Number
| Amount | |
|---|---|
| Gross payroll tax saving | $3,240 |
| − Compliance costs (payroll + CPA + CA franchise tax) | −$3,200 |
| − Extra income tax from lost QBI | −$369 |
| Net result | −$329 |
S-Corp election would cost Miguel $329 a year, not save him anything. The generic table's "Negative" label was directionally right, but for an incomplete reason — it would have shown "Negative" even bigger once the QBI cost is counted properly, and a Miguel who read only the gross $3,240 figure without the compliance-cost context might have elected anyway.
Why California Specifically Matters Here
Take away California's $800 minimum franchise tax and Miguel's compliance cost drops to $2,400, which would flip this to a positive $471 — a modest but real saving, not a loss. California is one of the few states that taxes the S-corp entity itself on top of personal tax, and that $800 minimum binds hardest exactly at lower income levels like Miguel's, where it's a larger share of the gross saving. A freelancer with the same numbers in a state with no S-corp entity tax would see a clearly different, positive answer.
What Would Change the Answer
Miguel's numbers would flip to a real, clear saving mainly by growing: at roughly $20,000 more net income (with proportional salary), the gross payroll-tax saving grows faster than the mostly-fixed compliance costs and the QBI loss, and the election starts to pay for itself. Nothing about Miguel's situation is unusual or a sign he did something wrong — $50,000 in California, with no existing CPA relationship, is simply below where this specific election pays off this year.
What Miguel Should Actually Do
- Don't elect based on the gross payroll-tax number alone. $3,240 looked like real money; it was consumed entirely by costs a payroll-tax-only comparison doesn't show.
- Re-run this calculation if his income grows or his CPA relationship changes. A CPA he already pays for other work, quoting a smaller premium for the S-Corp return, moves this calculation meaningfully — it's one of the larger inputs.
- Revisit this next tax year, not just when income changes — the Social Security wage base, QBI phase-out thresholds, and California's franchise tax minimum are all figures that can move with inflation adjustments.
Run Your Own Numbers
Miguel's result depends on his specific income, salary choice, state, and CPA cost — change any one of those and the answer moves.

Frequently Asked Questions
If a generic rule of thumb already said "Negative" at $50,000, what does Miguel's exact number add?
The direction was right but the reasoning was incomplete — a rule-of-thumb table built only from gross payroll-tax savings versus a compliance-cost range would call Miguel's situation "roughly break-even" on the numbers above ($3,240 saving versus up to $4,000 in costs), when the real answer is more clearly negative once the $369 QBI-driven income-tax cost is added on top. Someone whose compliance costs happened to land at the low end of that generic range could easily have been told "positive" by a table that never accounts for the QBI loss at all.
Would a different salary amount fix this for Miguel?
It would change the numbers in both directions at once, not just one. A lower salary increases the payroll-tax saving but shrinks further below the IRS's reasonable-salary comfort zone, while a higher salary raises payroll tax paid but also shrinks the QBI-eligible distribution, which changes the QBI cost too. There isn't a salary adjustment that fixes this purely by moving the dial — the more durable fix is more net income or a cheaper CPA relationship.
Does every state make this worse the way California does?
No — most states don't impose a separate entity-level tax on an S-Corp the way California does with its $800 minimum. In a state with no S-corp entity tax, Miguel's compliance cost would drop to $2,400 and his result would flip to a small positive number, though still marginal enough that the administrative hassle might not be worth it for the amount involved.
Is Miguel's 50% salary ratio itself a problem with the IRS?
No — a 50% salary-to-net-income ratio is well inside the range this tool treats as defensible (above roughly 38%, with below 30% flagged as real audit risk). The loss here isn't a compliance risk; it's a straightforward dollar result of compliance costs and a lost deduction outweighing a real but modest payroll-tax saving at this income level.
Should Miguel just stay a sole proprietor permanently because of this result?
Not necessarily — this is a this-year answer, not a permanent one. Miguel's own numbers show the answer flips to positive with meaningfully higher income or a lower CPA cost, so the right move is re-running the comparison when either changes materially, not treating today's negative result as a fixed conclusion about his business.
