The 5 most common payroll mistakes for small businesses

For many small business owners, managing payroll is a task they decide to take on themselves – often manually in an effort to save money. But this approach can backfire. The average cost of a payroll error is $291 per incident, according to a survey by Ernst & Young. Multiply that across several employees and mistakes, and the financial impact can quickly add up.

You might be wondering why payroll mistakes are so common. For one, payroll regulations change frequently, and staying current requires a significant time investment. Without automated systems and guidance, even the most organized business owners can feel overwhelmed.

But have no fear—with the right approach, these mistakes are preventable.

Understanding the nuances of common payroll mistakes—and how to avoid them—can help you stay ahead. Let’s break down the errors SMBs face most often and the steps you can take to protect your business.

1. Late or missed tax reporting

• The mistake: Missing federal or state tax deadlines can lead to automatic fines and interest charges. The IRS imposes up to 15% penalties for late payroll tax deposits.

• The solution: To avoid missed deadlines, mark tax filing dates on your calendar and set reminders at least a week in advance. Keeping accurate and organized payroll records throughout the year can also help ensure you’re prepared when deadlines approach. For added assurance, automate your tax filings with reliable payroll software such as TurboTax or you can outsource to a service like DianaHR to handle the process seamlessly.

2. Misclassified employees and independent contractors

• The mistake: Mislabeling employees as independent contractors (or vice versa) is one of the most common and costly payroll mistakes. If you’re unsure of the difference—employees receive wages subject to tax withholding and employer contributions like Social Security and Medicare, while independent contractors are paid in full and responsible for managing their own taxes. Misclassifying these roles can lead to legal and financial consequences.

• The solution: Familiarize yourself with IRS classification guidelines and state-specific rules to ensure compliance. Regularly review worker classifications, especially after role changes, and keep detailed records of contracts and job descriptions. If unsure, use IRS Form SS-8 for clarification or consult HR professionals to avoid penalties and stay compliant.

3. Overlooked state-specific payroll laws

• The mistake: State requirements like workers’ compensation, disability insurance, and paid leave rules often vary and are easily overlooked. Noncompliance can result in fines and audits.

• The solution: To stay compliant, regularly review your state’s labor department website or use the DOL website for up-to-date regulations. Automating compliance monitoring through payroll software can also help track changes and send alerts.

4. Inaccurate recordkeeping

• The mistake: Incomplete or disorganized payroll records can lead to errors and make audits a nightmare. Missing details like hours worked, wages paid, or tax filings can quickly snowball into more significant problems.

• The solution: Use payroll tools such as Quickbooks, Gusto, or ADP to keep clear, organized payroll data records. Regularly review and audit these records to catch and fix errors before they become compliance issues.

5. Overtime and wage calculation errors

• The mistake: Miscalculating overtime or failing to meet minimum wage requirements violates the Fair Labor Standards Act (FLSA) and can lead to penalties or lawsuits.

• The solution: Accurate tracking and calculation are essential to staying compliant. Tools like QuickBooks Time, Gusto, or ADP Workforce Now can automate overtime calculations and ensure compliance with FLSA standards. These platforms integrate time tracking, payroll processing, and compliance checks to reduce errors. And if you decide to partner with HR experts, DianaHR makes it easy to stay on top of wage laws and avoid costly mistakes.
