Outsourced Payroll Services for Small Business: 2026 Costs

TL;DR

The typical payroll outsourcing cost for a small business is $40 to $200 a month as a base fee, plus $5 to $15 per employee per month, depending on how many people you have and how much the provider handles (tax filing, direct deposit, new hire reporting, year end W-2s). Once you add the time spent reconciling payroll software against your books by hand, outsourcing can cost about the same or less. The part most payroll companies won’t tell you: payroll is one of the most common sources of month end close problems, and it mostly happens because payroll and bookkeeping are handled by two different people, or two different companies, who never talk to each other.

Key Takeaways

• Outsourced payroll services for small businesses usually run $40 to $200 a month as a base fee, plus $5 to $15 per employee per month.
• A full service payroll provider (tax filing, direct deposit, compliance reporting) costs more than a bare bones payroll app, but it removes the tasks most likely to cause a penalty if missed.
• Running payroll through a separate company from your bookkeeping creates a reconciliation problem every single pay period someone has to manually match payroll entries to the general ledger.
• Payroll tax penalties are strict and largely automatic. The IRS can assess a penalty the same month a deposit is late, regardless of whether the mistake was the business owner’s or the payroll provider’s.
• Bundling payroll with your outsourced bookkeeping means the same team closes your books and runs your payroll, so the numbers match by default instead of by cleanup.

What Do Outsourced Payroll Services for Small Business Include?

“Outsourced payroll” can mean very different things depending on who you ask, and the price difference comes almost entirely from what’s included.

At the basic end, you’re paying for software that calculates gross pay, withholds the right taxes, and issues paychecks or direct deposits. You’re still responsible for filing the payroll tax forms yourself, keeping up with new hire reporting, and fixing anything that goes wrong.

At the full service end, the provider calculates pay, deposits federal and state payroll taxes on your behalf, files the quarterly and annual payroll tax returns, handles new hire reporting to the state, prepares year end W-2s and 1099s, and manages things like wage garnishments and workers’ compensation reporting.

Most small businesses that get burned by payroll didn’t get burned by the math. They got burned by a missed tax deposit, a late filing, or a new hire report that never went in, because nobody was watching those tasks closely enough.

Small Business Payroll Service Cost in 2026

Small business payroll service cost varies by provider and by how many employees you have, but the pattern is consistent with Xero’s 2026 small business payroll guide, corroborated by QuickBooks’ 2026 cost of payroll guide.

These numbers cover the payroll outsourcing cost for processing on its own. If you’re comparing this to hiring someone in house to run payroll, remember that an in house hire also needs to learn (and keep up with) payroll tax law, which changes every year at both the federal and state level. Outsourced payroll shifts that compliance burden to the provider.

Choosing a Payroll Company for Small Business: Should It Be Separate From Your Bookkeeping?

This is the question almost nobody asks before they sign up with a payroll company, and it’s the one that causes the most pain later.

When payroll runs through one company and your books are kept by another person or firm, every pay period creates a reconciliation task: someone has to take the payroll report, break it into gross wages, taxes withheld, employer taxes, and benefits, and post all of that correctly to your general ledger. Miss a piece of it, and your labor costs look wrong on your P&L, your payroll tax liability account doesn’t match what’s actually owed, and your cash flow projections are off.

This is exactly the kind of problem we flagged in our guide to building a month end close process: payroll reconciliation is one of the most common places a monthly close goes sideways, specifically because of this handoff gap between payroll and bookkeeping.

When the same team runs both, this problem mostly disappears. The payroll entry is booked correctly the first time, because the person running payroll and the person closing the books are either the same person or working from the same system.

FAST FACT: Payroll tax deposit penalties are assessed automatically by the IRS and scale with how late the deposit is: 2 percent for a deposit one to five days late, 5 percent for six to fifteen days late, 10 percent beyond fifteen days, and 15 percent for amounts still unpaid more than 10 days after the IRS issues a delinquency notice.

In House Payroll vs Outsourced Payroll: What’s the Real Comparison?

The honest answer on in house payroll vs outsourced payroll is that a small business with one or two employees and simple, hourly pay can often get by with payroll software alone. Once you have multiple employees, any variation in pay (overtime, bonuses, commissions), or you’ve ever had a payroll tax notice land in the mail, the case for full service, bundled payroll gets stronger quickly.

How Breakwater Helps

Breakwater runs payroll as part of the same monthly process as your bookkeeping, not as a separate, disconnected service. That means payroll, payroll tax processing, and bookkeeping are handled by the same team, on the same monthly cycle described in our outsourced bookkeeping services guide. Payroll entries still need to be posted and checked each cycle, but there’s no separate provider and bookkeeper to reconcile between.

If you’re currently paying for a standalone payroll provider and a separate bookkeeper, it’s worth comparing that combined cost to a single bundled service — in most cases we’ve seen, the bundled approach costs about the same or less, and it removes an entire category of month end cleanup work.

Summary

Outsourced payroll services for small business typically cost $40 to $200 a month as a base fee plus $5 to $15 per employee, with full service providers (tax filing, deposits, compliance reporting) at the higher end of that range. The bigger decision isn’t the sticker price — it’s whether payroll runs through the same team that keeps your books, or through a separate payroll company that has no visibility into your general ledger. Separate systems mean someone has to manually reconcile payroll to your books every single pay period, and that’s one of the most common places a month end close breaks down.
