Payroll Company: Outsource Payroll or Keep It In-House?

Payroll is the job nobody thinks about until a paycheck is wrong or a deposit is late. If you’re weighing a payroll company against doing it yourself, the honest answer is that it depends, and we’ll say plainly when in-house is the better call. A disclosure first: we run payroll for small businesses, so we have a stake in this. Weigh what follows accordingly. The parts worth your attention are the cost math nobody shows you, who the IRS actually holds responsible, and what switching providers really involves.

Payroll Company or In-House Payroll: Which Costs More?

Usually not the payroll company, once you count your own time. Say payroll eats three hours every other pay period. That’s 26 runs, or 78 hours a year. If an hour of your time is worth $60, you’re spending $4,680 a year on a task that adds nothing to your sales. Run that against a provider’s fee before you decide. Then add the cost nobody budgets for: mistakes. A deposit that lands one to five days late costs 2% of the amount. Six to fifteen days late, 5%. Past that, 10%, and 15% once the IRS has sent a notice and ten days have gone by. (IRS — Failure to Deposit Penalty) For a single employee in a simple state, in-house software is hard to beat, and we’d tell you so.

Should You Outsource Payroll? Signs It’s Time

There’s no magic headcount. The first W-2 employee is where many owners start asking, and a few things usually settle it: a second state, tipped or overtime pay, garnishments, benefit deductions, or the first time you realize you missed a deposit date. Another sign is quieter. You dread payroll week. That tells you what the work is costing you.

Who’s accountable when payroll goes wrong?

You are. That surprises most owners. When a payroll service or reporting agent files and deposits for you, the IRS still holds the employer ultimately responsible for the returns and the taxes, even if you sent the money to the provider. Reporting agents have to say so in writing when you sign and at least quarterly after that. Owners and other responsible people can also face the Trust Fund Recovery Penalty, which can reach 100% of the unpaid withheld taxes. One arrangement changes this: a certified professional employer organization, or CPEO, which in most cases is solely liable for the employment taxes on wages it pays. That’s a different product with its own trade-offs. For an ordinary payroll company, the protection is contractual, so ask whether they’ll cover penalties caused by their own errors, and get that in writing. Then enroll in EFTPS yourself, so you can watch your deposits post. (IRS — Choosing a Payroll Service Provider)

How Much Does a Payroll Company Cost?

Most online payroll services charge a monthly base fee, commonly $20 to $100 or more, plus roughly $5 to $15 per employee. Published prices vary by provider and change often, so treat that as a ballpark. To compare quotes properly, total a full year for your real headcount. Say a $50 base plus $6 per employee, with eight employees. That’s $98 a month, or $1,176 a year. Then ask what’s extra, because year-end forms, off-cycle runs, setup, and additional states often are. A firm that also reconciles payroll to your books and handles agency notices costs more than software alone. Ours is a flat monthly fee, quoted after a free consultation, so the number doesn’t move when you run a bonus payroll.

Switching Payroll Providers Mid-Year

Easier than most owners fear, as long as one thing comes over cleanly: year-to-date wages. Social Security and unemployment wage caps count from January, and the W-2 has to show the full year, so the new provider needs the old one’s payroll register and tax liability history before the first run. The start of a quarter is the tidiest time to switch, because the quarterly return stays with one provider. It isn’t required, though. We’d plan a week or two. The sticky parts are the old provider’s final filings, the IRS authorization (make sure the new provider’s is on file and the old one has ended), and employees re-enrolling in direct deposit. Don’t cancel the old provider until you’ve confirmed their last deposit and return went through. And keep the old numbers beside you for the first run.

Frequently Asked Questions About Choosing a Payroll Company

Is outsourcing payroll cheaper than running it in house?

Usually not on cash alone. On time and risk, often yes. At three hours a run, biweekly payroll eats 78 hours a year, so put your own hourly rate on that before you decide.

What does a payroll service cost for a small team?

Typically a base fee plus a per-employee fee, with extras for year-end forms, extra states, and off-cycle runs. Add up a full year for your real headcount before comparing quotes. Ours is a flat monthly fee, quoted after a free consultation.

How hard is it to switch providers mid-year?

Easier than most owners expect if year-to-date wages come over cleanly. The sticky bits are the old provider’s final filings, the IRS authorization, and direct deposit. The start of a quarter is tidiest, but it isn’t required.

Who is responsible if a payroll run goes wrong?

You are, in the IRS’s eyes, even when a provider files for you. A CPEO is the main exception. Ask any provider whether they’ll cover penalties caused by their own errors, and get it in writing.

At what headcount does outsourcing start to make sense?

There’s no magic number. The first W-2 employee is where many owners start asking, and a second state, tips, or garnishments usually settles it.
