Payroll for One Employee (2026): The Simplest, Cheapest Way

Running payroll for one employee works exactly like running it for fifty — you still have to calculate withholding, file payroll taxes, and issue a W-2 — but the per-person cost of payroll software makes it the easiest case to automate. For a single employee (often the owner of an S-corp or LLC paying themselves a salary), full-service payroll software costs roughly $40 to $60 a month all-in and removes the deposit-schedule and filing headaches that cause most penalties. Doing it by hand is possible, but the time and penalty risk rarely justify the savings.

I run my own S-corp salary through payroll software, and the single-employee setup is genuinely the simplest version of payroll there is. Here’s how it works and what it costs.

Why one employee still means full payroll obligations

Whether you have one worker or one hundred, the IRS treats you the same. With even a single W-2 employee, you must:

• Obtain an EIN and register for state withholding and unemployment accounts.
• Withhold federal income tax, Social Security, and Medicare from each paycheck.
• Pay the employer share of Social Security and Medicare, plus federal and state unemployment tax.
• Deposit those taxes on the IRS-assigned schedule (monthly or semiweekly).
• File Form 941 quarterly, Form 940 annually, and state returns.
• Issue a W-2 in January and file it with the SSA.

Miss a deposit deadline and the penalty can be 2% to 15% of the amount due. That’s the real reason a single-employee business automates: not the math, but the calendar.

The S-corp owner case

The most common one-employee payroll is an S-corp owner paying themselves. If you’ve elected S-corp status, the IRS requires you to pay yourself a reasonable salary through payroll before taking the rest of your profit as distributions. That salary runs through payroll exactly like any employee’s — withholding, payroll taxes, a W-2.

This is where one-employee payroll earns its keep, because the reasonable-salary rule is an audit flashpoint. Software that runs the salary on schedule and files the forms keeps you clean. I cover the full split in my S-corp payroll guide.

Is payroll software worth it for one person?

Almost always, yes. The per-employee fee is tiny ($6 or less at most providers), so your cost is essentially just the base fee. For $40 to $60 a month you offload all tax calculation, deposits, filings, and the year-end W-2.

The DIY alternative means tracking IRS deposit schedules, filing 941s and 940s yourself, and preparing a W-2 — for one paycheck. People do it, but one missed deposit usually erases a year of savings.

What one-employee payroll costs

Prices are base plus one per-employee fee; confirm current rates with each provider. For a deeper price comparison, see my cheapest payroll software breakdown.

How to set up payroll for one employee

1. Get your EIN from the IRS (free, online, instant).
2. Register for state accounts — withholding and unemployment in your state.
3. Collect a W-4 and I-9 from the employee (even if it’s you).
4. Pick a pay schedule — biweekly or semimonthly is common; S-corp owners often run monthly.
5. Choose full-service software and enter your EIN, state IDs, and bank details.
6. Run the first payroll, then let auto-payroll handle subsequent runs.

That’s the whole setup. After the first run, a single-employee payroll is close to hands-off.

Common one-employee payroll mistakes

Even with a single paycheck, a few errors trip people up:

• Skipping payroll registration in your state. An EIN isn’t enough; most states require separate withholding and unemployment accounts before your first run.
• Missing tax deposit deadlines. The IRS assigns a monthly or semiweekly deposit schedule. A one-person business is still on a schedule, and a missed deposit triggers a penalty.
• Paying yourself with random transfers (S-corp owners). Distributions aren’t salary. Your reasonable salary must run through actual payroll with withholding, or the IRS can reclassify it.
• Forgetting the year-end W-2. One employee still gets a W-2 filed with the SSA by the deadline.
• Setting the salary and never reviewing it. For S-corp owners, a salary that stays flat while the business grows can look unreasonable on audit.

Full-service software prevents most of these by handling the registrations, deposits, and forms automatically once you’re set up. That’s the core argument for automating even a single paycheck.

Making payroll easier with Gusto

For a one-employee business — especially an S-corp owner paying themselves — Gusto is my default recommendation. It’s full-service, so it calculates withholding, deposits your payroll taxes on schedule, files your 941s, 940, and state returns, and issues your W-2 automatically. Auto-payroll means your salary runs on its own each cycle. Pricing is $49/month plus $6 per employee on the Simple plan, so a single-person payroll is about $55 a month with every tax filing included.

Gusto handles the S-corp reasonable-salary setup cleanly and is one of the easiest providers to onboard a one-person business onto. New customers who sign up through a referral link get a Visa gift card after their first paid payroll ($100 for fewer than 10 employees) plus three months free — no coupon to type.

Frequently asked questions

Do I need payroll software for just one employee?

You don’t strictly need software, but it’s the practical choice. With one employee you still owe quarterly 941s, an annual 940, state returns, tax deposits on schedule, and a year-end W-2. Software automates all of that for roughly $40 to $60 a month, far less than a single late-deposit penalty.

How do I pay myself as an S-corp owner?

You pay yourself a reasonable salary through payroll, withholding income and payroll taxes like any employee, and take remaining profit as distributions. The salary must reflect what you’d pay someone else for your work. See my S-corp payroll guide for the salary-versus-distribution split.

What’s the cheapest way to run payroll for one employee?

The cheapest full-service options run about $40 to $47 a month for a single employee — providers like Square Payroll, OnPay, and Patriot. True DIY costs nothing in software but exposes you to filing errors and penalties. Compare options in my cheapest payroll software post.

Can I run payroll for one employee myself by hand?

Yes, but you’ll manage IRS deposit schedules, file Form 941 quarterly and Form 940 annually, handle state returns, and prepare a W-2 — all for one paycheck. Most one-person businesses find software cheaper once they value their time and penalty risk.
