Payroll is one of those expenses that sneaks up on small business owners. You know you need it. You’re not always sure what it should cost — or what you’re actually paying for.

Here’s a straight answer on payroll cost for small businesses in Illinois and Wisconsin.

What Does Payroll Cost for a Small Business? The Short Answer

For most small businesses, full-service payroll costs between $75 and $250 per month depending on how many employees you have and what services are included.

Here’s a general range by employee count:

• 1–5 employees: $75–$125/month
• 6–15 employees: $125–$175/month
• 16–30 employees: $175–$250/month
• 30+ employees: Custom pricing based on complexity

These ranges assume full-service payroll — meaning someone else handles everything. Not just running checks, but also tax filings, direct deposit, employee onboarding, and year-end W-2s.

What’s Included in Full-Service Payroll for Small Businesses?

A true full-service payroll provider handles:

• Processing payroll each pay period (weekly, bi-weekly, or semi-monthly)
• Direct deposit to employee bank accounts
• Federal, state, and local payroll tax calculations
• Quarterly payroll tax filings (941, state equivalents)
• Annual W-2 preparation and filing
• New hire reporting
• Garnishment processing
• PTO tracking and accruals

If your current provider isn’t doing all of these things, you may be getting partial service — and handling some of this yourself without realizing it.

What Affects Payroll Cost for Your Small Business?

Number of employees — More employees means more processing time. Most providers charge a base fee plus a per-employee rate.

Pay frequency — Weekly payroll costs more to process than bi-weekly or semi-monthly. If cash flow allows, bi-weekly is the most cost-effective option for most small businesses.

Employee types — Hourly employees with variable hours, tipped employees, and employees in multiple states all add complexity — and cost.

Multi-state payroll — If you have employees in both Illinois and Wisconsin (or other states), you’ll have multiple state tax filing requirements. This adds to your monthly cost.

Add-on services — HR support, benefits administration, time and attendance tracking, and workers’ comp integration are often available as add-ons at additional cost.

DIY Payroll vs. Full-Service Payroll: What’s the Real Cost?

Some business owners try to handle payroll themselves using software like QuickBooks Payroll or Gusto. The monthly software cost is lower — often $40–$80/month. But the real cost includes:

• Your time — payroll takes 2–5 hours per month minimum
• The risk of errors — payroll tax penalties from the IRS and state agencies add up fast
• Staying current on tax law changes in both Illinois and Wisconsin
• Year-end W-2 preparation and filing complexity

For most small business owners, the time savings and penalty protection of full-service payroll are worth more than the monthly cost difference.

The Hidden Cost of Payroll Errors

Payroll mistakes are expensive. The IRS charges penalties for late or incorrect payroll tax deposits — starting at 2% and going up to 15% of the unpaid amount depending on how late the payment is.

For a business with a $10,000 monthly payroll tax liability, a late deposit penalty could run $200–$1,500 per incident. A few of those and you’ve wiped out any savings from doing payroll yourself.
