Payroll processing mistakes can snowball into serious financial and legal consequences for your business.

While it might seem like just another frustrating administrative task, getting payroll right is essential for keeping your employees happy and staying on the good side of the IRS. 

To help you navigate this tricky territory, we’re breaking down the five most common payroll mistakes small businesses make and how to avoid them.

1. Missing Tax Deadlines

Deadlines, deadlines, deadlines.

One of the most frequent mistakes small businesses make is missing tax payment due dates. Being a bit late might seem harmless at first, but this often result in penalties and interest that can quickly add up. Worse, the IRS doesn’t take kindly to delayed payments, as that money technically belongs to your employees.

Missing deadlines doesn’t just hurt your bottom line with penalties—it damages your credibility. Your employees rely on you to handle their withholdings responsibly.

Set reminders for tax deadlines or, better yet, invest in an automated payroll system that will schedule these payments for you. 

These systems will support you with timely filing and payment, reducing the risk of human error. If any of this feels overwhelming, work with a trusted CPA who can keep you compliant.

2. Misclassifying Employees and Contractors

Employee or contractor? The difference matters more than you might think.

Misclassification can lead to major problems, including audits and fines. It might save you money on payroll taxes in the short term, but it can land you in hot water down the road. 

Employees are subject to payroll taxes and labor protections, while contractors are not—but the rules defining these roles are strict.

The IRS and Department of Labor take these errors seriously. Misclassifications can result in back taxes, penalties, and even lawsuits from affected workers.


When in doubt, consult a payroll expert or a CPA, like us here at Pantana CPA, to be sure everyone is categorized correctly. Familiarize yourself with IRS guidelines for worker classification, and review your team’s roles periodically to stay compliant.

3. Not Using Online Payroll Services

Can you believe it’s 2024, and yet some businesses are still processing payroll manually? Not only is this time-consuming, but it’s also prone to errors that could cost your business BIG.


Manual payroll processing increases the likelihood of calculation errors, delayed payments, and misfiled taxes. These mistakes can result in lost time, frustrated employees, and financial penalties.


Online payroll systems streamline the process, calculate taxes accurately, and ensure all forms are filed on time. Many platforms even offer direct deposit options, making payday stress-free for you and your team. 

If you’re still stuck in the manual payroll era, it’s time to upgrade. The time savings alone make it worth the investment.

4. Poor Payroll Processing Records

Record-keeping might not be fun, but it’s a legal requirement.

Incomplete or non-compliant payroll records can lead to audits and fines. From pay stubs to tax filings, having everything organized and up to date can save you a lot of stress in the long run.

Without proper records, you’re left vulnerable to disputes from employees or inquiries from the IRS. Accurate records are your first line of defense against audits and legal issues.


Implement a digital filing system to store payroll records securely. Many payroll software programs automatically generate and save reports, which makes compliance a breeze. 

Be sure to hold onto documents for at least three years, as required by federal law, and consider periodic reviews to ensure all data is complete and accurate.

5. Mismanaging Deductions and Benefits

Benefits and deductions can get complicated really quickly. For instance, health insurance should typically be pre-tax, but if it’s set up incorrectly, your employees could end up paying unnecessary taxes.

Similarly, miscalculating retirement contributions or neglecting to record cash bonuses properly can cause issues for both you and your employees.


Errors in deductions can lead to employee dissatisfaction and even legal disputes. Mismanagement might also result in penalties from the IRS or Department of Labor if incorrect amounts are reported.


Work with a payroll processing specialist to set up deductions correctly from the start. Regularly audit your payroll processes to ensure deductions and benefits comply with federal and state laws. If your team grows or benefit offerings change, update your systems accordingly to avoid missteps.

Why These Payroll Preparation Mistakes Matter

The consequences of payroll mistakes aren’t just financial. Penalties, interest, and lawsuits are all possibilities. Imagine an employee discovering their withholding taxes weren’t paid—this could lead to IRS troubles for both them and you.

In extreme cases, the IRS can freeze your accounts or even escalate enforcement actions, such as seizing assets. On the employee side, payroll errors can damage morale, trust, and retention, especially if mistakes lead to delayed or incorrect pay.

How to Protect Your Business

Don’t try to do it all yourself!

Using a professional payroll processing service or outsourcing to a CPA can make a world of difference. These experts will ensure deadlines are met, forms are filed correctly, and everything is compliant.

If you’re a business owner with a remote team, it’s even more critical to stay organized, as different states have different tax laws. Remote work complicates payroll because you may need to withhold taxes for multiple states. A knowledgeable CPA can navigate these complexities, so you don’t have to.
