best payroll software for solo business owners

Being a solo business owner means you're the CEO, the accountant, and the person cutting the checks. But "paying yourself" isn't as simple as it sounds — especially if you've elected S Corp status to reduce self-employment tax or you're a freelancer juggling multiple 1099 clients. Spreadsheets can work, but they won't file your quarterly taxes or remind you about payroll deadlines. That's where dedicated payroll software comes in.

We've looked at the top options for one-person businesses, from S Corp owners to sole proprietors, and picked the services that actually make sense when you're a team of one.

best payroll software for solo owners

1. gusto — best for s corp solo owners

Gusto's Solo plan is built specifically for one-person businesses. It handles full payroll, including W-2s and 1099s, and guides you through S Corp compliance to maximize self-employment tax savings1. You also get access to 401(k) and health benefits, which is rare for a solo plan. If you've elected S Corp status or are considering it, Gusto is the most complete option.

2. quickbooks self-employed — best for 1099 freelancers

QuickBooks Self-Employed is the industry standard for sole proprietors and 1099 contractors2. It automatically categorizes expenses, tracks mileage, and estimates quarterly taxes. It's not a full payroll system — you won't get W-2 processing — but for freelancers who don't need that, it's the most streamlined way to stay tax-ready all year.

3. square payroll — best for square pos users

If you already run your business through Square (taking payments, managing inventory), Square Payroll is the natural extension. It syncs sales data directly to payroll, so you don't have to manually calculate contractor payments or employee hours. It's ideal for solo owners who want one ecosystem for everything.

4. xero — best for accounting-first owners

Xero's payroll integrates directly into its accounting ledger, meaning you never have to double-enter data. For solo owners who already use Xero for bookkeeping, adding payroll is seamless. It handles tax filings and pay runs for one employee without the overhead of larger systems.

why these picks

Each pick targets a different business structure because "solo owner" isn't one size fits all:

• Gusto handles the complexity of S Corp compliance — reasonable compensation, shareholder distributions, and self-employment tax optimization1. It's the only major service with a dedicated Solo plan.
• QuickBooks Self-Employed is built for the 1099 economy. It automates expense categorization and quarterly tax estimates, and integrates directly with TurboTax2. No W-2 processing, but freelancers rarely need it.
• Square Payroll eliminates friction if you're already processing payments through Square. Sales data flows into payroll automatically.
• Xero is for the solo owner who lives in their accounting software. Adding payroll means everything stays in one ledger, no reconciliation needed.

All four services scale with you if you eventually hire, but they're designed to not overwhelm you with enterprise features you'll never use.
