6 Payroll Mistakes That Can Cost Your Business Thousands
Payroll errors are expensive — in penalties, back taxes, and employee trust. Here are the six most common payroll mistakes small business owners make and how to avoid them.
Payroll mistakes are more common than you'd think — and more expensive. The IRS estimates that 40% of small businesses pay payroll penalties each year. Here are the six mistakes most likely to cost you.
1. Missing Tax Deposit Deadlines
Payroll tax deposits must be made on a strict schedule — monthly or semi-weekly, depending on your payroll size. Missing a deposit by even one day triggers a penalty starting at 2% and climbing to 15% for deposits more than 10 days late.
Fix: Set calendar reminders and use payroll software that handles deposits automatically.
2. Misclassifying Workers
Treating employees as independent contractors to avoid payroll taxes is one of the most scrutinized areas of tax compliance. If the IRS reclassifies your contractors as employees, you owe back payroll taxes, penalties, and interest.
Fix: Understand the classification rules and when in doubt, consult a tax professional.
3. Incorrect Withholding
Withholding too little means employees owe a large tax bill at year-end. Withholding too much means you're holding their money unnecessarily. Both create problems.
Fix: Make sure employees complete accurate W-4s and update them when their situation changes (marriage, new child, second job).
4. Not Keeping Up with Minimum Wage Changes
Federal, state, and local minimum wages change regularly. Paying below the applicable minimum wage exposes you to Department of Labor penalties and employee lawsuits.
Fix: Subscribe to payroll compliance updates or use a payroll service that stays current automatically.
5. Failing to Issue W-2s and 1099s on Time
W-2s and 1099-NECs must be issued by January 31. Late or incorrect forms result in IRS penalties of $60–$310 per form.
Fix: Start gathering contractor W-9s in November so you're ready to file in January.
6. Mixing Payroll and Operating Funds
Running payroll from your general operating account makes it hard to track payroll costs and can lead to overdrafts if you're not careful.
Fix: Open a dedicated payroll bank account and fund it before each pay run.
