S-Corp Payroll Rules for a Single-Member Owner (2026 Guide)

You formed an LLC, elected S-corporation tax status, and now your accountant says you need to “run payroll” — for one person. Yourself.

This guide explains the rules every single-member S-corp owner needs to follow in 2026, the deadlines, the common mistakes, and the cheapest way to run a one-person payroll.

Not tax advice. S-corp compensation is a judgment call with real IRS consequences. Use this guide to have a better conversation with your CPA, not to replace one.

The core rule: you must pay yourself a reasonable salary

When you’re an S-corp shareholder who works in the business, the IRS treats you as an employee. That means you must pay yourself W-2 wages before taking profits out as distributions.

The incentive for owners is obvious: W-2 wages carry Social Security and Medicare taxes (15.3% combined up to the wage base), while distributions don’t. Pay yourself $0 salary and take everything as distributions, and you’d skip payroll taxes entirely. The IRS knows this, so it requires your salary to be “reasonable compensation” for the work you do.

How is “reasonable” decided?

There’s no fixed percentage or formula. The IRS and courts look at factors like:

Your training, experience and duties
Time and effort you devote to the business
What comparable businesses pay for similar services
What you’d have to pay someone else to do your job
The company’s gross receipts and profits
Your history of salary vs. distributions

Practical approach: document a salary based on market data for your role (Bureau of Labor Statistics wage data is a common starting point), adjusted for your hours and the company’s ability to pay. Keep that documentation with your corporate records.

What happens if your salary is too low?

The IRS can recharacterize distributions as wages, then assess the unpaid employment taxes, penalties and interest. Taking distributions with no salary at all in a profitable year is the classic red flag.

What payroll looks like for a one-person S corp

Even with one employee, you have the same core payroll obligations as any employer.

Taxes withheld from your paycheck

Federal income tax — based on your Form W-4
Social Security — 6.2% on wages up to the 2026 wage base of $184,500
Medicare — 1.45% on all wages, plus an additional 0.9% employee-only tax on wages over $200,000
State and local income tax, where applicable

Taxes the S corp pays as employer

Social Security — matching 6.2%
Medicare — matching 1.45%
FUTA (federal unemployment) — 6% on the first $7,000 of wages, usually reduced to 0.6% with the state credit (about $42/year)
State unemployment (SUTA) — rates and rules vary; some states exempt corporate officers or let them opt out

Filings and deadlines

Filing	What it is	When
Federal tax deposits	Withheld income tax + FICA	Monthly or semiweekly, based on your lookback period
Form 941	Quarterly federal payroll return	Last day of the month after each quarter
Form 940	Annual FUTA return	January 31
Form W-2 / W-3	Your wage statement, filed with the SSA	January 31
State returns	Withholding and unemployment	Varies by state

Very small employers whose annual employment tax liability is $1,000 or less may be notified by the IRS to file Form 944 annually instead of quarterly 941s.

Missing a deposit is the most expensive mistake. IRS failure-to-deposit penalties start at 2% for deposits up to five days late and climb to 10% after 15 days. A full-service payroll provider that makes deposits and files returns for you is the easiest way to avoid them.

Health insurance: the 2% shareholder rule

If your S corp pays for your health insurance, it’s treated differently than for regular employees. As a “more-than-2% shareholder”:

The S corp pays or reimburses the premiums.
The premiums are added to your W-2 Box 1 wages (income tax wages).
They are not subject to Social Security or Medicare tax when paid under a qualifying plan.
You may then be able to claim the self-employed health insurance deduction on your personal return.

Get step 2 wrong and you can lose the deduction. Tell your payroll provider you’re a 2% shareholder with company-paid health insurance — most can handle the W-2 reporting automatically once it’s set up.

Retirement contributions through payroll

An S corp owner can contribute to a Solo 401(k) through payroll. For 2026:

Employee deferral: up to $24,500 (plus an $8,000 catch-up if you’re 50+; $11,250 if you’re 60–63)
Employer contribution: up to 25% of your W-2 wages
Combined limit: $72,000 (excluding catch-up contributions)

Employer contributions are based only on W-2 salary — not distributions — which is one reason an artificially low salary can cost you more than it saves.

Distributions: the other half of your pay

After salary, you can take remaining profits as shareholder distributions. Key rules:

Distributions aren’t run through payroll and have no withholding.
You pay income tax on the S corp’s profit on your personal return (via Schedule K-1), whether you distribute it or not — so set aside money for quarterly estimated taxes.
Distributions can’t exceed your stock basis; amounts above basis are generally taxed as capital gains.
With a single owner, pro-rata distribution rules are simple — but if you ever add a shareholder, distributions must be proportional to ownership.

How often should a single-member S corp run payroll?

There’s no legal requirement to pay yourself on a particular schedule, but regular payroll (monthly is common for owner-only S corps) looks more like real compensation than a single year-end paycheck and keeps tax deposits steady. Most payroll providers include unlimited runs, so frequency doesn’t change your cost.

Cheapest payroll software for a one-person S corp

For an owner-only payroll, base fees matter far more than per-employee fees. Here’s what one employee costs per month at October 2026 list prices:

Provider	Plan	Monthly cost for 1 employee	Notes
Square Payroll	Full-service	$41	Multi-state included; no POS required
Patriot Software	Full Service	$42	Year-end W-2 filing included; tax filing guarantee
Wave Payroll	Tax Service	$46	Auto tax filing only in some states; best with Wave accounting
Gusto	Simple	$55	Covers penalties from its own filing errors; strong owner tools
OnPay	Payroll Essentials	$55	Multi-state included
QuickBooks Payroll	Core	$57	Best if your books are in QuickBooks Online
Patriot Software	Basic (you file taxes)	$21	Cheapest, but you make deposits and file returns

Our take:

Lowest-cost full service: Square Payroll ($41) and Patriot Full Service ($42) are effectively tied. Patriot includes year-end filings and a tax filing guarantee, which matters if you’re the kind of owner who’d rather never think about this.
Best if you use QuickBooks Online: QuickBooks Payroll costs ~$15 more per month but posts payroll entries straight to your books, which your CPA will appreciate at tax time.
Avoid self-file plans unless you’re comfortable making federal deposits and filing Forms 941/940 yourself. The savings disappear with one late-deposit penalty.

Common single-member S-corp payroll mistakes

Taking distributions with no salary. The fastest way to invite IRS scrutiny.
Forgetting health insurance on the W-2. Costs you the self-employed health insurance deduction.
Running payroll once at year-end. Large one-time deposits are easy to miss, and penalties apply per deposit.
Ignoring state registration. You still need a state withholding account and, in most states, an unemployment account.
Paying personal expenses from the business and calling it salary. Reimburse legitimate business expenses through an accountable plan instead — those reimbursements aren’t wages.

FAQ

Do I have to run payroll if I’m the only employee of my S corp? Yes, if you perform services for the business and take money out of it. Your compensation for those services must be paid as W-2 wages through payroll.

What’s a reasonable salary for an S corp owner? There’s no IRS percentage. It should reflect what you’d pay someone else to do your job, considering your duties, hours and the business’s profits. Document how you arrived at the number.

Can I pay myself through payroll only once a year? It’s not prohibited, but regular payroll (monthly or quarterly) is more defensible and keeps tax deposits manageable.

What’s the cheapest payroll service for a one-person S corp? At October 2026 list prices, Square Payroll ($35 + $6 = $41/month) and Patriot Software Full Service ($37 + $5 = $42/month) are the lowest-cost options that make your tax deposits and file returns for you.
