DIY Payroll
Payroll Service
A payroll service saves you $2,312 to $2,552/year at your current setup.
The time cost of DIY exceeds the subscription cost of outsourcing. This gap widens as you add employees.
IRS Penalty Risk: The Hidden Cost of DIY
The IRS assesses approximately $6.8 billion in payroll tax penalties annually. The most common penalties for small businesses are late deposits (2% to 15% of the deposit amount depending on how late), incorrect filing amounts, and failure to file Form 941 quarterly returns. The average penalty per small business incident is $845.

Incident rate with full-service provider
Probability-adjusted expected penalty cost for DIY payroll: $85 to $170 per year. Full-service payroll providers guarantee accurate filing and typically cover any penalties resulting from their errors, making your expected penalty cost effectively zero. This risk transfer alone is worth $85 to $170/year of the service subscription.
When DIY Still Makes Sense
Sole proprietors paying themselves
With only one person on payroll, the time cost is minimal (30 to 60 minutes per run) and free tools like Wave can handle the basics.
1099-only businesses
If all your workers are independent contractors, you only need to issue 1099s at year-end. A payroll service is unnecessary overhead.
Seasonal businesses
If you only run payroll 3 to 4 months per year, paying a monthly subscription for 12 months does not make financial sense. DIY for the active months may be cheaper.
Very low time cost
If the person handling payroll has an effective hourly rate under $25 and has accounting experience, the time cost of DIY is genuinely lower than outsourcing for small teams.
One state, simple payroll
A single-state business with all salaried employees, no benefits deductions, and monthly payroll has the simplest possible setup. DIY tools handle this well.
