ESPer Diem Workers and Overtime Pay
Per diem overtime rights depend on employee status, legal coverage, and what a payment covers. A genuine expense reimbursement may be excluded from the overtime regular rate, but a payment labeled per diem that functions as compensation for work may need to be included.
What Does Per Diem Mean for Workers?
Per diem can describe a daily wage, an as-needed work arrangement, or an allowance for expenses such as lodging and meals during a business assignment. Those meanings aren’t interchangeable. An as-needed schedule doesn’t itself determine overtime eligibility. An allowance paid alongside hourly wages raises a different question: whether it reimburses business expenses or pays for work.
When Does an Allowance Affect Overtime Pay?
Covered nonexempt employees generally must receive federal overtime for hours over 40 in a workweek at a time-and-a-half rate. The regular rate generally includes compensation for work unless a statutory exclusion applies; it isn’t necessarily the stated hourly rate.
Reasonable reimbursement for expenses incurred on the employer’s behalf or for its benefit may be excluded. The payment must genuinely serve that purpose and reasonably approximate qualifying expenses. A label alone doesn’t establish an exclusion.
Must the Allowance Stay Below the Federal Per Diem Rate?
No. Federal regulations provide a safe harbor for the amount of qualifying business-travel reimbursements at or below specified federal or IRS allowances. The payment must still satisfy the other reimbursement requirements.
An amount above those limits isn’t automatically unreasonable. The employer may need other support to show its reasonableness. Conversely, staying below a government rate doesn’t establish that a payment functions as reimbursement rather than wages.
What Does Recent DOL Guidance Explain?
In a November 8, 2024, opinion letter, the U.S. Department of Labor addressed daily tool-and-equipment payments to inspectors working for an oil-and-gas service company. The guidance emphasized the payment’s function and whether it reasonably approximated expenses.
The letter is fact-specific agency guidance, not a court judgment or a finding against a named employer. It illustrates why changing a payroll label doesn’t determine the overtime treatment.
How Could a Wage Allowance Change the Calculation?
Assume a covered nonexempt employee works 50 hours at $20 per hour, receives a $500 weekly allowance, and has no other compensation. The $1,000 in hourly earnings cover straight time for all 50 hours. Compare a fully excludable reimbursement with an allowance that is entirely wages.
| Calculation | Qualifying reimbursement | Payment entirely wages |
|---|---|---|
| Regular hourly rate | $20 | ($1,000 + $500) ÷ 50 = $30 |
| Additional premium for 10 overtime hours | $20 × 0.5 × 10 = $100 | $30 × 0.5 × 10 = $150 |
| Total wages plus allowance | $1,600 | $1,650 |
The difference is $50 for this week. Both totals include the $500 payment. This simplified federal example assumes the stated treatment of the entire allowance; it doesn’t decide whether a particular payment qualifies. State rules and other pay can change the result.
What Records Help Review Per Diem Pay?
Keep pay stubs, allowance policies, assignment dates and locations, hours, travel records, and available expense documentation. Note how payroll determines the allowance and who pays lodging or meals. Preserve records you can lawfully access.
A review should address federal and relevant state law, the work location, expenses, and pay arrangement. And be aware that wage claims have deadlines.
