How do I manage driver payroll and per diem payments?
Driver payroll is more complicated than standard employee payroll because of variable pay structures and the per diem component. Drivers might be paid by the mile, by the load, hourly, or some combination. Per diem adds another layer because it’s handled differently than regular wages for tax purposes.
Per diem is a daily allowance for meals and incidental expenses when drivers are away from home overnight. For truck drivers specifically, the DOT allows a higher per diem rate than standard business travelers. The advantage is that per diem paid under an accountable plan isn’t subject to income tax or payroll taxes. This saves money for both the driver and the company.
To qualify as an accountable plan, the per diem must meet IRS requirements. The expenses need a business connection, the driver must substantiate the days away from home, and any excess must be returned. In practice, this means tracking overnight trips accurately rather than paying a flat per diem regardless of actual travel.
Track days away from home carefully. ELD data, trip logs, and dispatch records all serve as documentation. The driver needs to have been away from their tax home overnight for per diem to apply. A day trip for a local delivery doesn’t qualify.
In your payroll system, set up per diem as a separate pay type that’s excluded from taxable wages. QuickBooks and most payroll platforms have options for non-taxable reimbursements. If you’re mixing per diem into regular wages, you’re overpaying payroll taxes and shortchanging your drivers on take-home pay.
For the wage portion, decide on your pay structure and document it clearly. Mileage-based pay requires accurate tracking of miles driven. Per-load pay needs clear definitions of what counts as a load. Hourly pay for local drivers needs time tracking. Whatever method you use, put it in your driver agreements so there’s no confusion later.
Transportation companies often make the mistake of paying per diem for days drivers are actually home, or not tracking overnight stays properly. These errors create tax liability issues or mean you’re paying more payroll taxes than necessary.
Multi-state payroll adds complexity. Drivers working across state lines may trigger withholding requirements in multiple states. Some states have reciprocity agreements, others don’t. Getting this wrong means surprise tax bills for drivers or the company at year end.
