Gusto
Cheapest full-service payroll with automated tax filing
Gusto is not free, but at $40/month + $6/employee/month it is the lowest-cost full-service payroll platform that handles tax calculations, direct deposit, tax filing, W-2/1099 generation, and new hire reporting. For a 10-person company, that is $100/month — the practical floor for payroll that runs without manual tax work.
Gusto offers a free trial that lets you set up your company, add employees, and run a test payroll before committing. This is the closest to free payroll you can get with a platform that actually files your taxes. The trial period varies (typically 1-3 months for the first payroll run), and you can cancel before being charged.
For teams searching for free payroll software, Gusto's value becomes clear when you calculate the cost of doing payroll manually: calculating federal and state tax withholdings, remitting payments to tax authorities, filing quarterly 941 forms, and generating year-end W-2s. A single tax penalty for late filing ($50+ per form) can exceed Gusto's monthly fee.
Strengths for this audience
- Automated federal, state, and local tax filing eliminates the most error-prone part of DIY payroll
- Direct deposit, W-2/1099 generation, and new hire reporting are included at the base price
- Benefits administration (health, dental, 401k) available as add-ons within the same platform
Limitations to know
- Not free — $40/month base plus $6/employee/month is the minimum cost
- International payroll is not supported — US-only for direct payroll processing
- The Simple plan lacks multi-state payroll — you need the Plus plan ($80/month base) for that
