# Common Payroll Mistakes Small Employers Make

Payroll errors are expensive because they involve trust fund money, meaning taxes withheld from employees that the business holds on behalf of the government. Most mistakes are preventable with a few routines. Here are the ones that show up again and again.

**Quick answer.** Calling someone a contractor to avoid payroll does not make them one. If the relationship looks like employment, the business may owe back taxes, penalties and interest, and fixed weekly payments with no invoices is a classic red flag.

## Treating employees as contractors

Calling someone a contractor to avoid payroll does not make them one. If the relationship looks like employment, the business may owe back taxes, penalties and interest. A pattern of fixed weekly payments with no invoices is a classic red flag. See the guide on contractor versus employee for the signals.

Hiring in another state? [Employer registration in another state](/bookkeeping/out-of-state-employer-registration).

If you are unsure, ask a CPA or employment attorney before the next payment, not after a letter arrives.

## Paying payroll taxes late or not at all

Cash gets tight and the tax deposit is the money sitting in the account. Using it for rent or inventory is tempting and dangerous, since the penalties are heavy and owners can be personally responsible. Keep withheld taxes in a separate account or at least in a tracked liability, and make deposits on schedule.

If you cannot make a deposit, contact the agency or your advisor immediately. Silence is the worst response.

## Wrong withholding setup

Entering an employee's forms incorrectly, missing a state setting, or failing to update after a move or a marital change leads to over- or under-withholding. Review each new employee's first paycheck against their forms. Ask employees to update their forms when their situation changes, and keep the new form on file.

Remote employees can create withholding obligations in states where they live or work. Ask your payroll provider or CPA before onboarding someone out of state.

## Mishandling owner pay and benefits

Owners of some entity types should not be paid like ordinary employees, and others must be. Treat this as a structure question for your CPA. Also watch for fringe benefits such as personal use of a company car or certain insurance, which may need to be added to taxable wages.

Paying employees in cash off the books creates a record gap that can affect them in unemployment claims and loan applications, and affects you in an audit.

## Weak records and missed filings

Lost time sheets, missing signed forms, unreconciled liability accounts and late quarterly returns all appear in audits and notices. Each quarter, reconcile the payroll liability accounts in the books to the filed returns. Differences mean something was missed or misposted.

Keep payroll records for the period your advisor recommends. A short monthly checklist that confirms deposits made, returns filed and reports saved takes a few minutes and prevents most of these issues.

## A monthly five-minute payroll review

Once a month, open the payroll summary and ask four questions. Were all deposits made on time? Does the number of employees match who actually worked? Are there any unusual swings in a person's pay? Has anyone's address or status changed? Write the answers in a one-line log. The log becomes proof of diligence if an agency ever asks.

Employees also catch errors. Ask them to report anything odd on a pay statement within the same pay period, and fix it in the next run.

## Common questions

**What should I do if I discover a past payroll mistake?**

Gather the facts and speak with a CPA or payroll specialist. Agencies have procedures for corrections, and prompt, accurate fixing usually helps.

**Is a payroll provider responsible for errors?**

Providers differ. Read your service agreement, and remember you are still the party responsible to the agencies.
