What Drives Payroll Service Cost for Small Businesses
Payroll service cost depends on far more than employee count. Most payroll providers hide key cost drivers upfront. Understanding these factors helps you avoid overpaying for unused features or underpaying for critical services.
Employee count and pay frequency
Most payroll software charges a monthly base fee plus a per-employee fee. OnPay charges $49/month plus $6 per employee; a 10-person company pays roughly $109/month. Pay frequency also matters: weekly payroll (52 runs/year) costs more than biweekly (26 runs) if your provider charges per pay run. OnPay offers unlimited pay runs at no extra charge, which benefits businesses needing frequent processing.
Tax complexity and multistate payroll
Multistate payroll significantly increases payroll service cost. Some providers include multistate handling at no extra charge; others charge $20-$50/month per additional state. OnPay includes multistate payroll without extra fees, potentially saving hundreds annually compared to per-state pricing models.
Payroll Service Pricing Models Explained
Payroll services use two primary pricing structures. Understanding the difference helps you calculate your true cost before committing.
Monthly base fee plus per-employee charges
The dominant model charges a fixed monthly fee ($19-$49) plus per-employee charges ($4-$8 per person per pay period). SurePayroll's full-service plan costs $29.99/month plus $5 per employee; a 15-person company pays roughly $1,258 annually. This model offers predictability but costs rise linearly with hiring.
Full-service versus basic payroll plans
Full-service plans include tax filing and year-end forms; basic plans leave tax filing to you. Full-service costs $10-$20/month more but eliminates separate accountant fees ($500-$1,000 annually). For most small businesses, full-service is worth the premium. Basic payroll suits solopreneurs or contractor-only businesses.
Real-world cost scenarios by business profile
Scenario 1: 3-person startup, biweekly payroll, single state, ~$750/year (base $29.99/month + per-employee fees; tax filing included).
Scenario 2: 10-person service business, biweekly payroll, multistate, ~$1,656-$2,256/year (base $29.99/month + per-employee fees; multistate fees vary by provider).
Scenario 3: Contractor-only business, 5 contractors, monthly processing, ~$620-$820/year (basic payroll $19.99/month + contractor tracking; you handle 1099 filing separately).
How pay frequency and complexity change the bill
Pay frequency and complexity shift costs significantly. Weekly payroll adds $50-$100/month if charged per run (OnPay's unlimited runs eliminate this). Multiple states add $50-$150/month per state. Hourly workers, garnishments, and benefits administration add further costs. Always plug your actual employee count, pay frequency, state count, and complexity into each provider's calculator, the cheapest base fee often masks higher per-employee or per-state costs.
Payroll Software Cost Per Employee: What to Expect
Most providers charge $4-$8 per employee per pay period. Growing from 10 to 25 employees adds $1,080-$1,440 annually in incremental payroll service cost. OnPay's $6/employee covers unlimited pay runs and multistate payroll; SurePayroll's $4-$5/employee covers basic processing. The cheaper option isn't always better if you need bundled features.
Free Payroll Software for Small Businesses: Pros and Limitations
Free payroll software handles basics (wage calculation, direct deposit, pay stubs) but lacks tax filing and compliance support. It suits solopreneurs with simple payroll, but the time cost of managing taxes manually often exceeds full-service payroll fees once you have multiple employees. Free software also leaves you liable for missed deadlines, incorrect withholdings, and compliance errors, risk that compounds as payroll grows.
Payroll Service Features and Add-On Costs
Base payroll pricing covers the essentials. But most businesses need additional features that come at extra cost. More importantly, what those features actually cover, and what liability they shield you from, varies widely between providers.
Tax filing and compliance services: What's actually included
Full-service tax filing includes federal and state tax withholding, quarterly and annual form filing (941, 940, W-2s), EFTPS deposits, and error correction. It does NOT include penalty abatement, IRS representation, or tax planning.
Basic payroll includes wage calculation, direct deposit, and pay stubs, you file taxes yourself or hire an accountant separately ($500-$1,500 annually). This often exceeds the $10-$20/month premium for full-service payroll.
Compliance support and liability protection
Compliance support includes wage and hour guidance, benefits administration support, regulatory updates, and access to tax experts. It reduces misclassification and overtime violation risks but is not legal representation. Some providers bundle it with full-service payroll; others charge $10-$30/month. It's worth the cost if you have multistate payroll or mixed employee classifications.
Direct deposit, year-end forms, and contractor support
Direct deposit is standard in most payroll plans and is included at no extra charge. It allows employees to receive wages via electronic transfer rather than paper check.
Year-end form generation (W-2s, 1099-NECs) is usually included with full-service plans but may cost extra with basic plans. If your provider charges per form, budget $5-$10 per W-2 and $2-$5 per 1099-NEC. A 15-person company generating 15 W-2s and 5 1099s could pay $100-$125 in form fees if not bundled.
Contractor support is a separate feature. If you pay independent contractors, you need 1099 tracking and filing. Some payroll services bundle 1099 processing with full-service payroll. Others charge $2-$5 per contractor per month. If you work with 10 or more contractors regularly, this adds $20-$50/month. If you have only occasional contractor payments, basic 1099 tracking may be sufficient.
Multistate payroll and state-specific fees
Multistate payroll is where add-on costs become unpredictable. If all your employees work in one state, your tax filing is straightforward. But if you have employees across multiple states, you're managing different state tax rates, filing deadlines, and compliance rules.
Some providers include multistate payroll at no extra charge. OnPay, for example, includes multistate payroll in its base per-employee fee. SurePayroll may charge $20-$50/month per additional state beyond the first. If you operate in three states, that's an extra $40-$100/month, or $480-$1,200 annually.
Before signing up, ask your provider explicitly: "Does your pricing include payroll for employees in multiple states, or do you charge per state?" The answer can swing your annual cost by $500-$1,500.

Choosing features based on your risk tolerance
Full-service payroll with compliance support costs more upfront but transfers tax filing and regulatory risk to the provider. If you lack payroll expertise or operate in multiple states, this is the safer choice. You pay more, but you avoid the risk of missed deadlines, incorrect withholdings, or compliance violations.
Basic payroll with external tax filing (accountant-handled) is cheaper if you have simple, single-state payroll and a trusted accountant. You keep more control but retain the risk of errors.
Free or DIY payroll is realistic only for solopreneurs with no employees or very simple payroll. As soon as you have multiple employees or multistate operations, the liability risk and time cost of managing taxes yourself usually exceed the cost of outsourced payroll.
In-House Payroll Versus Outsourced: True Cost Comparison
Many small business owners assume handling payroll in-house saves money. The math often tells a different story.
In-house payroll requires someone to learn tax law, manage calculations, file forms, and stay current on regulatory changes. That person is usually you or an employee. Your time has value. Even if you spend just 5 hours per month on payroll (learning software, processing runs, filing taxes), that's 60 hours annually. At $50 per hour, that's $3,000 in labor cost. Full-service payroll software costs roughly $1,200-$2,400 annually for a 15-person company. The math favors outsourcing.
There's also liability. Payroll mistakes, missed tax deposits, incorrect withholdings, late filings, carry penalties and interest. A single missed deadline can cost hundreds of dollars. Outsourced payroll providers assume this liability. In-house payroll leaves you exposed.
Outsourced payroll is most cost-effective when:
Your business has 5 or more employees
You have multistate payroll
You lack payroll expertise
Your time is better spent on revenue-generating work
In-house payroll makes sense only for solopreneurs or very small teams with simple, single-state payroll and someone with tax knowledge on staff.
How to Choose the Right Payroll Service for Your Budget
Start by calculating your actual payroll service cost for your specific situation. Don't compare headline prices. Use these steps:
Count your employees and determine pay frequency. A 12-person company running biweekly payroll has different needs than a 12-person company running weekly payroll.
Identify your tax complexity. Single-state payroll with W-2 employees is simpler than multistate payroll with contractors. Know which you have.
Calculate the monthly cost for each provider. Take the base fee, add the per-employee charges for your headcount, and add any state-specific fees. Don't forget optional features you actually need.
Factor in what you're not paying separately. If the payroll service includes tax filing, don't pay an accountant for that separately. If you're handling it in-house, add your time cost.
Compare total first-year cost, not just monthly fees. Some providers charge setup fees or onboarding costs. Others offer discounts for annual prepayment. Build a full-year picture.
The best payroll service for your budget isn't always the cheapest. It's the one that covers your specific needs without forcing you to pay for features you won't use or leave you scrambling to fill gaps elsewhere.

Frequently Asked Questions
What is the average cost of a payroll service for a small business?
Payroll service costs vary widely based on employee count, pay frequency, and service level. Most providers charge a monthly base fee (typically $20-$50) plus a per-employee fee ($3-$10 per employee per pay run). A small business with 10 employees on biweekly payroll might spend $100-$200 monthly, while a 30-employee business could pay $200-$400. Total annual costs depend heavily on whether you choose basic payroll processing or full-service plans that include tax filing and compliance.
Is payroll software cheaper than outsourcing payroll to a professional service?
Payroll software generally has lower direct costs than outsourced payroll services, but the comparison depends on your needs. Software requires time investment to run payroll correctly and stay compliant with tax regulations. Outsourced payroll services cost more upfront but eliminate setup, training, and ongoing management time. For businesses with 1-20 employees and straightforward payroll, software may be cost-effective. For complex payroll (multiple states, contractors, benefits) or if your time is valuable, outsourced services often deliver better total value despite higher monthly fees.
What fees should I compare when choosing a payroll provider?
Compare the monthly base fee, per-employee charge, and per-payroll-run fees first. Then examine whether tax filing, payment processing, and year-end forms (W-2s, 1099s) are included or cost extra. Check for setup fees, direct deposit fees, and charges for multistate payroll or contractor-only payroll. Some providers charge for integrations with accounting software like QuickBooks Online. Ask about unlimited pay runs, some plans limit you to a set number monthly, with overage fees for additional runs. Request a quote based on your exact employee count and pay frequency for an accurate comparison.
Is there a free payroll service for small businesses?
Some payroll software offers free tiers with limited functionality, typically for very small businesses (1-2 employees) or specific use cases like household payroll. Free plans usually lack tax filing, direct deposit, or multistate support. As your business grows, you'll outgrow the free tier and need to upgrade to a paid plan. For most small businesses with employees and tax obligations, free payroll software is a starting point only. Professional payroll services that handle full compliance and tax filing typically require paid plans from the start.
