Running payroll for a 1–5 person S-corp has one wrinkle a normal small business does not: the IRS expects owner-employees to take a reasonable salary through payroll (not just distributions). The right software runs that owner payroll, files the taxes automatically, and keeps you compliant — without a bookkeeper. These three do it well, best-fit first.
1. Gusto — best for most small S-corps
Gusto is the top pick because it handles the exact things an S-corp owner needs: full-service payroll with automatic federal and state tax filing, easy setup for a reasonable owner salary, direct deposit, and clean separation of wages from distributions come tax time. From $49/mo + $6/employee with transparent pricing and an interface a non-accountant can run, it is the easiest way to stay compliant. For the scaling question, see our Gusto vs Rippling comparison.
2. QuickBooks Payroll — best if you already use QuickBooks
If your books already live in QuickBooks, adding QuickBooks Payroll keeps payroll and accounting in one system — automatic wage and tax calculations, filings, and year-end forms, with penalty protection on higher tiers. The integration removes double entry, which is the main reason to choose it over Gusto. Confirm current pricing, as tiers change.
3. OnPay — simple flat-rate alternative
OnPay is a straightforward, well-reviewed payroll service that includes tax filing, benefits, and HR basics at a simple flat rate. It is a strong option for an owner who wants reliable payroll without the wider Gusto feature set. Along with Patriot, SurePayroll, and ADP Run, it is worth a look if Gusto and QuickBooks do not fit.
The S-corp reasonable-salary rule
The IRS requires an S-corp owner who works in the business to pay themselves a reasonable salary through payroll before taking distributions — underpaying to dodge payroll tax is a common audit trigger. Good payroll software helps by running that owner salary, withholding and remitting Social Security/Medicare and income tax, and documenting it cleanly. Set the salary to match your role and local market; a CPA can confirm the number.
Frequently asked questions
What is the best payroll software for a single-owner S-corp?
Gusto is the best pick for most single-owner S-corps — it runs owner payroll, files taxes automatically, and separates salary from distributions, all from $49/mo + $6/employee. QuickBooks Payroll is better if your accounting is already in QuickBooks.
How do I run payroll for an S-corp?
Set a reasonable owner salary, then use payroll software to calculate wages and withholdings, remit federal and state payroll taxes (usually quarterly), and file year-end forms. Tools like Gusto automate the filings and record-keeping, which keeps you compliant with minimal manual work. Confirm your salary figure with a CPA.
Does QuickBooks work for S-corps?
Yes — QuickBooks (with QuickBooks Payroll) handles S-corp payroll, expense tracking, and tax-compliant reporting, and keeping payroll in the same system as your books reduces errors. It is the natural choice if you already use QuickBooks for accounting.
How much does small-business payroll software cost?
Gusto starts at $49/mo + $6/employee. QuickBooks Payroll and OnPay pricing varies by tier — confirm current rates on their sites. For a 1–5 person S-corp, expect roughly $50–$80/mo all-in, which is usually far cheaper than a bookkeeper handling payroll manually.
The bottom line
For most small S-corps, Gusto is the best payroll software — it runs owner payroll, files taxes automatically, and stays affordable and transparent. Choose QuickBooks Payroll if your books are already in QuickBooks, or OnPay for a simple flat-rate alternative. Set a reasonable salary, connect your bank, and let the software keep you compliant.
