DIY Payroll vs Hiring a Payroll Service
For very small businesses, doing payroll yourself can seem cheaper. But when you factor in your time, compliance risk, and the true cost of errors, the break-even point often arrives sooner than expected.

The Real Cost of DIY Payroll
Your Time Has Value
Running payroll manually for 10 employees takes approximately 2-3 hours per pay period once you factor in data collection, calculations, tax deposit preparation, and record-keeping. At bi-weekly payroll, that is 52-78 hours per year.
If your time is worth $50/hour, that is $2,600-$3,900 per year in opportunity cost, far exceeding the $600-$1,200 annual cost of a basic payroll service.
IRS Penalties Are Automatic
The IRS automatically charges penalties for late payroll tax deposits. The penalty schedule is 2% for 1-5 days late, 5% for 6-15 days late, and 10% for deposits more than 15 days late. A missed deposit of $5,000 in payroll taxes can result in a $500 penalty.
Even a single missed deposit due to a misunderstanding of the deposit schedule can generate penalties that exceed an entire year of payroll service fees.
Tax Law Changes Are Constant
Federal and state payroll tax rates, limits, and filing requirements change every year. Social Security wage base limits, SUTA rates, minimum wage updates, and new withholding tables all require updates to your payroll calculations.
Payroll services update their software automatically for all regulatory changes. DIY payroll requires you to track these changes yourself or risk using outdated rates.
Break-Even Analysis
Most business advisors recommend using a payroll service once you have more than 3-5 W-2 employees. At that scale, the time savings, compliance protection, and automation value typically exceeds the monthly fee.
