Why S-Corp Owners Must Run Payroll (and What Gusto Costs)

#The S-corp payroll requirement

When you file Form 2553 and elect S-corp tax treatment, you get a real benefit: profits that flow to you as distributions are not subject to self-employment tax (15.3%). That is the whole point of the election.

But the IRS has a condition. You must also pay yourself a reasonable W-2 salary for the work you do in the business before taking those distributions. This is called reasonable compensation, and it has to reflect what you would pay someone else to do your job.

Why? Because without the rule, every S-corp owner would just take all income as distributions and pay zero FICA. The payroll requirement is what keeps the election legitimate.

There is no set percentage. The IRS looks at what you do, how much you work, and what others are paid for the same job. Many owners start with market pay for their role and check it against profit. See how the IRS benchmarks reasonable comp for the full methodology.

#The cost of skipping payroll

Distributions without payroll is the most-audited S-corp pattern. The IRS knows what it looks like: S-corp owner takes $200,000 in distributions, runs zero payroll, pays no FICA on any of it.

Here is what that looks like in practice. Say you took $150,000 in distributions and paid yourself nothing in wages. If the IRS decides $80,000 should have been wages, you owe $12,240 in back FICA (15.3% of $80,000). On top of that, you owe interest on that amount for every year it was unpaid. A potential 20% accuracy-related penalty on the underpayment can apply too.

Running payroll on a salary you can support cuts this risk a lot. The IRS can still question a salary it thinks is too low, so keep notes on how you chose it. The FICA you pay on your salary is the cost of keeping the election clean.

#Why Gusto

Once you know payroll is required, you need a provider. The main options for solo S-corps are Gusto, Run by ADP, QuickBooks Payroll, Patriot, and OnPay. All of them work. Here is why Gusto is the default for most ETS clients:

It was built for small businesses. The setup flow is the cleanest for solo S-corp owners. Gusto guides you through each phase, including state registrations and federal enrollment.

It handles all the filings automatically. Quarterly Form 941, annual Form 940, year-end W-2s, and state filings all happen without you doing anything extra after setup. See S-corp payroll 941 compliance for what each filing covers.

Multi-state payroll is available on some Gusto plans. Check which plan covers the states you need, since it can cost more.

It integrates with Kick. Payroll entries sync automatically when you pair Gusto with Kick for bookkeeping.

When Gusto is not the right call: practices with 30-plus employees and complex benefits may need more depth from Run by ADP or Paychex. Businesses with heavy union or certified payroll requirements should use specialty providers. For most small S-corp owners, Gusto is a good fit.

#What payroll costs to run

The ongoing cost of Gusto for a solo S-corp owner:

• Platform fee: about $49/month (Simple plan)
• Per-person fee: $6/month for the owner as the only W-2 employee
• Solo owner total: about $55/month, or about $660 per year (check Gusto’s page for the current price)

State registrations may run extra if you use Gusto’s done-for-you service (around $199 per state). Most owners register directly with their home state agency for free and just enter the account number into Gusto once it issues.

Payroll tax filings and W-2s are included. Check Gusto’s page for contractor and state registration fees.

The time burden is light once setup is done. Running payroll each cycle takes about five minutes. Gusto pre-fills the wages and you click approve. The only ongoing work: update your reasonable comp amount at the start of each year, and keep state registrations current if you expand to new states.

Compare that to the cost of skipping it. The FICA savings from avoiding payroll on an $80,000 salary is about $12,240 per year. But that savings disappears entirely if the IRS audits and reclassifies. The $624 annual Gusto cost is the price of keeping the structure legitimate.

State unemployment accounts can take a few weeks to issue, and the time depends on your state. The actual hands-on work is about 1 to 2 hours spread across that window.

The full step-by-step walkthrough covers every phase: account creation, state SUI registration, federal tax setup, owner profile and W-4, pay schedule configuration, 2% shareholder health insurance add-back, accountable plan reimbursements. It ends with the first paycheck checklist.

#Common questions

Do I have to use Gusto specifically? No. Run by ADP, Patriot, QuickBooks Payroll, and OnPay all work. Gusto is the default for ETS clients because it is the simplest setup experience for solo owners and integrates cleanly with our bookkeeping stack.

How often do I need to run payroll? Monthly or semi-monthly is most common for solo S-corp owners. Weekly adds unnecessary overhead. The IRS expects a regular cadence throughout the year, not a single lump-sum payment at year-end.

Can I wait until December to start payroll? No. Running one big paycheck in December raises the same audit flags as skipping payroll entirely. Payroll should start close to your S-corp effective date and run on a consistent schedule.

Does payroll replace the S-corp tax return? No. Gusto handles payroll filings (941, 940, W-2). The S-corp’s own tax return (Form 1120-S) is filed separately. The W-2 from Gusto feeds your personal return and the 1120-S for the same year.

What if my comp number changes mid-year? Update it in Gusto. Future paychecks use the new amount. Document the change in a memo so there is a paper trail if the amount is ever questioned.

Does Gusto handle 1099 contractors too? Yes. Contractors can be added to Gusto and paid as 1099s. At year-end Gusto generates the 1099-NEC. Contractor payments do not generate FICA withholding.
