How Bookkeepers Can Protect Clients From Payroll Data Errors

Payroll errors are the most sensitive data errors a business can make — they affect employees directly. Here's how bookkeepers can catch and prevent payroll data problems before they reach paychecks.

Key Takeaways
  • Payroll errors caught before the run cost nothing; errors caught after cost corrections plus relationship damage
  • A total payroll variance over 5% from the prior period warrants explanation before approval
  • Hours outside a defined range for any employee should be flagged and verified before processing
  • YTD errors compound — a single incorrect correction can affect W-2 accuracy at year-end
  • Reconcile payroll to your bank account after every run — confirm total debit matches provider report

Why Payroll Errors Hit Differently

When you make an accounting error, you correct it and move on. When you make a payroll error — an employee underpaid, an overpayment that needs to be recovered, a tax withholding calculated incorrectly — you're directly affecting someone's livelihood.

Employees notice every discrepancy. One uncorrected payroll error destroys trust in ways that take months to rebuild. Two creates a culture of suspicion.

The Most Common Payroll Data Errors

Wrong pay rate: An employee received a raise that was approved but not updated in the payroll system. They've been paid at the old rate for 6 weeks.

Hours entered incorrectly: 84 hours entered instead of 48 (typo: 4→8, shifted place). Or regular hours entered in the overtime column (or vice versa), changing the rate applied.

Missing time entries: An employee forgot to submit their timesheet. Payroll ran anyway with an estimated amount or zero. The correction requires an off-cycle payment.

Wrong deductions: An employee enrolled in a new benefit plan. The deduction wasn't activated in payroll. They've been covered but not paying their share — which must now be recovered.

Year-to-date (YTD) errors: A correction made incorrectly that throws off YTD totals, which affects W-2 accuracy at year-end.

The Payroll Pre-Processing Review

Before approving any payroll run:

Gross pay reasonableness check Compare total payroll this period to last period. Any variance over 5% deserves explanation. A spike in total payroll might mean a rate error, a duplicate entry, or an unauthorized bonus.

Sohovi automatically finds every duplicate in your dataset — including near-matches — and shows you exactly which rows are affected.

Employee count check How many employees are on this payroll? Compare to last period. Any new additions or unexpected removals?

Hours verification For hourly employees, verify total hours are within a reasonable range. No employee should be working 200 hours in a biweekly period without a clear explanation. Flag anything outside your defined range for review.

Deduction verification For each employee with a deduction change this period, verify the change was authorized and the amount is correct.

After Payroll Runs

  • Reconcile payroll to your bank account: confirm the total debit matches your payroll provider's report
  • Verify all payroll taxes were deposited on time
  • Update YTD records in your accounting system
  • File any required reports (state, federal) on schedule

Payroll errors caught before the check runs cost nothing. Payroll errors caught after the check runs cost the correction process plus the relationship damage.

Sohovi gives you the data quality picture you need to make the case for fixing it — and to track improvement over time.

Frequently Asked Questions

What should I do when a payroll error is discovered after checks are issued?

Notify the employee immediately and explain what happened. Issue a correction in the next payroll cycle for underpayments. For overpayments, discuss a recovery plan with the employee — many states have restrictions on recovering overpayments. Document everything.

How do I catch wrong pay rate errors before payroll runs?

Maintain a salary/rate register outside your payroll software. Before each payroll run, compare the rates in your payroll software to the register. Any discrepancy gets resolved before approval.

What's the most dangerous payroll data error?

YTD errors that carry through to W-2s. A correction entered in payroll incorrectly (e.g., as a negative pay entry rather than a correction entry) can corrupt YTD figures and produce incorrect W-2s, requiring W-2c amendments and creating potential tax issues for employees.
