What to Do When You've Been Calculating Overtime Wrong

Fixing Overtime Calculation Errors: Legal Steps
8:19

You’re reviewing payroll for your small retail store when you notice a mistake: your employees’ overtime has been paid at their regular rate, not the required 1.5x rate. This error could mean thousands in back wages, Department of Labor (DOL) fines up to $2,074 per violation, and angry employees threatening lawsuits. Miscalculating overtime is a costly mistake that can erode trust and destabilize your business if not corrected swiftly.

Step 1: Identify the Overtime Errors

Your first step is to pinpoint where and how you’ve miscalculated overtime to understand the scope of the problem.

Review payroll records for the past 2–3 years (the typical statute of limitations) using software like Gusto ($40/month). Check for errors, such as paying overtime at 1x instead of 1.5x the regular rate, misclassifying non-exempt employees as exempt, or excluding bonuses from overtime calculations. Verify compliance with the Fair Labor Standards Act (FLSA) and state laws—some states, like California, require daily overtime after 8 hours.

Document errors in a Google Sheets file: affected employees, incorrect rates, hours, and dates. Calculate the total underpayment to estimate liability. The Department of Labor provides FLSA overtime rules to guide your review.

 

Example – Jane’s Café: Spotting the Error

Jane, a café owner, discovered her payroll system paid overtime at regular rates for 10 employees over 18 months. Reviewing Gusto records, she found 500 hours of underpaid overtime, totaling $7,500. Jane noted each error in a spreadsheet, confirming the issue stemmed from a software misconfiguration.

Identifying errors, as Jane did, gives you a clear picture of the damage, setting the stage for corrections.

Pro Tip – Check State-Specific Rules

Research state overtime laws in your Google Docs notes, as they may exceed FLSA requirements (e.g., California’s daily overtime). Use your state’s labor department website to confirm rules, ensuring your calculations align with both federal and state standards.

Step 2: Consult a Lawyer or HR Expert

Overtime errors carry legal and financial risks, so consult a professional to assess liabilities and plan corrective actions.

Hire an employment lawyer or HR consultant ($200–$500/hour) to review your payroll records and errors. They’ll estimate back wages (e.g., $7,500 in underpayments) and potential DOL penalties ($2,074 per willful violation). They’ll also check if employees could claim liquidated damages (double the back wages) or legal fees in a lawsuit. The consultant will recommend steps, like notifying employees or self-reporting to the DOL to reduce penalties.

Save their advice in a Google Drive folder and agree on a timeline, like 30 days, for corrections.

Pro Tip – Request a Liability Estimate

Ask your consultant for a written estimate of back wages, penalties, and legal risks ($100–$200 extra). Store it in Google Docs to budget for payments and prioritize fixes, ensuring you’re prepared for financial and legal outcomes.

Expert guidance helps you navigate the legal maze and minimize costly mistakes.

Step 3: Calculate and Pay Back Wages

Compensating employees for underpaid overtime is your next step to resolve the error and avoid lawsuits.

Recalculate overtime at 1.5x the regular rate for all affected hours, including bonuses or shift differentials if required. For example, an employee earning $20/hour should get $30/hour for overtime. Use Gusto to run calculations, ensuring accuracy. Issue payments via direct deposit or checks, including a letter explaining, “We found an error in overtime calculations and have paid $1,200 for hours from January 2024–May 2025.”

Have employees sign an acknowledgment of payment to close the issue. Document payments and letters in Google Drive for DOL audits.

 

Example – Mike’s Retail: Settling Back Wages

Mike, a retailer, underpaid 8 employees $10,000 in overtime over 2 years. He recalculated wages in Gusto, issued checks with a clear explanation, and had employees sign receipts. Mike paid within 30 days, avoiding a DOL complaint. His transparency resolved the issue cleanly.

Paying back wages, as Mike did, shows good faith and reduces legal risks, keeping employees satisfied.

 

🗲

Pro Tip – Include Interest on Back Wages

Add 1–2% interest to back wage payments, calculated in Google Sheets, to account for delays (e.g., $100 interest on $5,000). This voluntary step demonstrates fairness and may deter lawsuits, as employees see you’re going beyond the minimum.

Step 4: Update Payroll Processes

Fixing the error isn’t enough—update your payroll systems to ensure accurate overtime calculations moving forward.

Switch to or configure payroll software like Gusto to automate overtime at 1.5x rates, factoring in state rules. Train HR or managers on FLSA and state laws, using a 1-hour session with DOL resources—cover exempt vs. non-exempt status and bonus inclusions. Conduct monthly payroll audits in Gusto to catch errors early, reviewing 5–10 employee records.

Update employee handbooks with clear overtime policies, like “Overtime paid at 1.5x for hours over 40/week.” Save training logs and audit reports in Google Drive.

Pro Tip – Automate Overtime Tracking

Set up Gusto to flag overtime hours automatically, alerting you when employees exceed 40 hours/week. Test settings monthly to ensure accuracy, reducing manual errors and keeping your payroll compliant with minimal effort.

Updated processes prevent repeat errors, saving time and legal headaches.

Step 5: Communicate and Rebuild Trust

Overtime errors can erode employee morale, so communicate transparently to restore confidence and maintain a positive workplace.

Notify employees via email or meetings within 24 hours of issuing back wages, stating, “We corrected an overtime calculation error and paid all owed wages.” Apologize sincerely and outline new measures, like “We’ve upgraded our payroll system to ensure accuracy.” Offer a Q&A session or a Google Forms link for questions, addressing concerns promptly.

Recognize employee patience with a small gesture, like a $50 gift card or extra break time, to boost morale. 

 

Example – Laura’s Bakery: Restoring Confidence

Laura, a bakery owner, underpaid $8,000 in overtime to 12 employees. After paying back wages, she emailed staff, apologized, and explained her new Gusto system. She held a Q&A and gave each employee a $25 coffee voucher. Laura’s openness rebuilt trust, and staff morale recovered quickly.

Transparency, like Laura’s, shows employees you value fairness, strengthening loyalty.

 

🗲

Pro Tip – Create a Communication Script

Draft a Google Docs script for your employee notification: “We regret the error, have paid all wages, and implemented [fixes].” Practice it to convey sincerity. This ensures consistent messaging, reducing misunderstandings and reinforcing trust.

Conclusion

Miscalculating overtime is a serious mistake, but with the right approach, you can correct it and strengthen your business. By identifying errors, consulting experts, paying back wages, updating processes, and rebuilding trust, you’ll comply with laws and keep employees happy. Start today by auditing your payroll system—accuracy is your best defense.
