Do you need payroll software?
If you're a profitable sole proprietor, the answer might surprise you — and the math is worth understanding before your next tax season.
The tax case for incorporating
Sole proprietors pay self-employment tax — currently 15.3% — on every dollar of Schedule C profit. That covers both halves of Social Security and Medicare, and it adds up fast. When you incorporate as an S-Corp (or elect S-Corp tax treatment on your LLC), you only pay payroll taxes on the salary portion of your income. The rest flows to you as a distribution, free of self-employment tax.
Here's what that difference looks like in real numbers, comparing a sole proprietor to an S-Corp owner at the same income level:
| Business Profit | Sole Proprietor Taxes | S-Corp Taxes | Your Savings |
|---|---|---|---|
| $50,000 | $11,509 | $7,952 | $3,557 |
| $100,000 | $29,310 | $22,691 | $6,619 |
| $250,000 | $96,648 | $85,190 | $11,458 |
| $500,000 | $217,743 | $202,939 | $14,804 |
The bottom line: even at $50,000 in profit, incorporating saves you more than $3,500 per year — well above the ~$1,000 annual cost to maintain a corporation. The breakeven point is lower than most people expect.
Is this the right move for you?
Incorporating isn't the right call for everyone — especially early on. Here's a quick gut-check. You're likely a strong candidate if:
Your Schedule C profit is consistently above $40–50k per year
You're currently a sole proprietor or single-member LLC
You pay yourself out of business profits rather than a W-2 salary
You're in California (or planning to operate there)
You'd rather keep an extra $3–6k than send it to the IRS
If most of those describe you, it's probably worth a conversation with a CPA. The paperwork to incorporate is genuinely manageable — and once it's done, maintaining an S-Corp is mostly just keeping up with payroll.
"But doesn't an S-Corp mean I have to run payroll?"
Yes — and this is where most people pause. The IRS requires that S-Corp officer-employees receive a reasonable salary via W-2 payroll. You can't avoid it by taking everything as distributions. Here's what that actually means in practice:
What payroll actually looks like for an owner-operator
People imagine payroll as something that requires a dedicated employee or an expensive service. For an owner-only or very small team, the actual mechanics are five steps:
1. Set your salary
Work with your CPA to land on a reasonable annual salary. You'll enter this once when you set up your employee profile.
2. Run payroll on schedule
Weekly, bi-weekly, or semi-monthly — pick your cadence. Enter hours if applicable, confirm the numbers, and generate checks or direct deposits.
3. Make tax deposits
Federal and California payroll taxes are deposited on a schedule set by the IRS and EDD. The app tracks your deposit due dates so nothing slips.
4. File quarterly returns
Form 941 (federal) and DE 9 (California) are due four times a year. Your payroll data is already in the system — it's mostly review and submit.
5. Issue W-2s at year end
January comes around, you generate W-2s from the payroll records already on file. Print or e-file. Done for the year.
That's it. For a one- or two-person S-Corp in California, that's the whole job. No HR system. No benefits administration. No seat-based pricing. Just payroll, done right, on time.
