Payroll might seem like a straightforward administrative task—calculate hours, cut checks, submit taxes. But in reality, payroll is one of the most complex and high-stakes functions of running a business. One small error can lead to fines, audits, employee dissatisfaction, or even legal trouble. Whether you’re a small business owner managing payroll in-house or relying on basic software, it’s easy to overlook the details. And payroll mistakes can cost you—big time.
Here are the top 7 payroll mistakes we see small businesses make, and how to avoid them.
1. Misclassifying Employees and Contractors
One of the most common and costly errors is incorrectly classifying workers. If you’re treating a contractor like an employee (or vice versa), you’re exposing your business to IRS penalties and back taxes.
💡 Tip: Use the IRS 20-factor test or consult a professional. When in doubt, it’s safer to classify someone as an employee.
2. Missing Payroll Tax Deadlines
Payroll taxes come with strict due dates—and late payments trigger interest, penalties, and even liens. If you’re manually managing payroll or using outdated systems, it’s easy to miss a deadline.
💡 Solution: Use a payroll service (like RAC Consulting’s) that automatically calculates, withholds, and files taxes on your behalf—on time, every time.
3. Failing to Keep Accurate Records
Federal law requires you to retain payroll records for at least three years, and timecards for two. Missing or incomplete records not only violate labor laws—they also leave you vulnerable in case of an audit.
💡 Tip: Digitize and store all payroll-related records securely, and back them up regularly.
4. Mismanaging Overtime Pay
Not all salaried employees are exempt from overtime. Misapplying the Fair Labor Standards Act (FLSA) rules—especially in industries like healthcare, tech, and skilled trades—can lead to lawsuits and back wages.
💡 Solution: Regularly review employee classifications and wage laws. When in doubt, confirm with a payroll expert.

5. Inaccurate Time Tracking
If your employees clock in manually or use an outdated system, rounding errors and buddy-punching can lead to significant losses. Worse, it can result in underpayment claims or disputes.
💡 Tip: Implement an accurate time-tracking system that integrates directly with payroll software.
6. Not Staying Updated on Tax Law Changes
From changes in minimum wage laws to new tax credits and local regulations, payroll is a moving target. What was accurate last year might not be this year.
💡 Solution: Partner with a payroll provider that proactively monitors changes and keeps your business compliant.
7. Neglecting Employee Communications
Payroll isn’t just about numbers—it’s about trust. When employees see mistakes on their paychecks or receive confusing tax documents, it damages morale and credibility.
💡 Tip: Communicate clearly about pay structures, benefits, and deductions. Ensure your payroll system produces easy-to-understand pay stubs and W-2s.
What It Could Cost You
These payroll mistakes might seem small, but the cost adds up:
- IRS Penalties for Late Filing: Up to 15% of unpaid taxes
- Misclassification Penalties: Fines + back pay + interest
- Legal Fees from Employee Disputes: Thousands in settlements
- Lost Productivity: Time spent fixing preventable errors
