Is Truck Driver Per Diem Legal? The Most Common Questions Trucking Company Owners Ask
Published: August 10th, 2026
Executive Summary
Truck driver per diem is one of the most misunderstood payroll topics in trucking. Many fleet owners have heard about it but aren’t sure whether it’s legal, who qualifies, how much it saves, or what records are required.
The good news is that truck driver per diem is an IRS-approved reimbursement program, not a loophole. When implemented correctly, it can increase driver take-home pay while reducing payroll taxes and workers’ compensation costs for the trucking company. The key is following the IRS rules and working with a payroll provider that understands trucking.
This guide answers the most common questions trucking company owners ask before implementing a per diem program.
Who Is This For?
This article is for:
- Trucking company owners
- Fleet executives
- Safety and operations managers
- Payroll administrators
- Anyone evaluating trucking payroll services
- Companies looking for payroll for trucking that understands driver compensation
What Is Truck Driver Per Diem?
Truck driver per diem allows qualified over-the-road drivers to receive part of their compensation as a tax-free meal and incidental expense reimbursement instead of taxable wages.
Because that reimbursement is not subject to Social Security and Medicare taxes, both the driver and the trucking company benefit.
Unlike many tax-saving ideas circulating around the trucking industry, this is not a loophole or creative accounting strategy. It is specifically authorized by the IRS through annual Revenue Procedures.
Is Truck Driver Per Diem Legal?
Yes.
This is the easiest question to answer.
The IRS has provided special transportation industry per diem rules for decades and publishes updated guidance and reimbursement rates nearly every year.
For the current period, Revenue Procedure 2024-68 establishes an $80 per day transportation industry rate. That makes truck driver per diem an official IRS program, not an aggressive tax strategy.
Can Every Trucking Company Offer Per Diem?
Almost every over-the-road trucking company can.
Generally speaking, companies with drivers who travel away from home overnight are good candidates.
This includes many:
- Long-haul carriers
- Regional carriers
- Dedicated fleets
Drivers generally qualify when they travel away from home overnight while operating under hours-of-service regulations.
Local or last-mile operations typically do not qualify because drivers usually return home each day.
Does Per Diem Cost the Company Money?
No.
It usually saves the company money.
Because part of the driver’s compensation becomes a reimbursement instead of taxable wages:
- Employer Social Security taxes decrease.
- Employer Medicare taxes decrease.
- Workers’ compensation premiums often decrease because taxable payroll is lower.
- Drivers receive more take-home pay.
For many fleets, this creates a rare win-win situation where both the trucking company and its drivers benefit simultaneously.
Depending on driver count and utilization, savings can reach approximately $2,500 per driver annually for the company while drivers may increase take-home pay by roughly $4,000 to $5,000 per year.
Should You Require Every Driver to Participate?
Probably not.
While employers may generally have the ability to require participation, forcing drivers into a per diem program is rarely the best business decision.
Some drivers have legitimate concerns, including:
- Future Social Security benefits
- Previous negative experiences
- Misunderstanding how per diem works
Instead of forcing participation:
- Listen to the driver’s concerns.
- Educate them.
- Explain both the benefits and tradeoffs.
- Allow them to opt out if they remain uncomfortable.
Losing a good driver costs far more than the payroll tax savings generated through per diem. Building trust is often the better long-term strategy.
Can You Simply Pay Seven Days of Per Diem Every Week?
No.
This is one of the biggest mistakes trucking companies can make.
Per diem must reasonably reflect qualifying travel.
That means:
- Vacation days do not qualify.
- Home time does not qualify.
- Days off generally do not qualify.
- Drivers should only receive per diem for qualifying travel days.
If every driver receives 365 days of per diem every year regardless of actual travel, the IRS could determine that the payments should have been taxable wages instead.
Following the rules protects both your company and your drivers.
What Records Should You Keep?
Fortunately, most trucking companies already have the records they need.
Examples include:
- Bills of lading
- Dispatch records
- Transportation Management System (TMS) records
- Payroll records
These records typically demonstrate:
- When the trip began
- Where freight originated
- Delivery dates
- Driver assignments
- Payroll payments
Good documentation leads to much easier audits if questions ever arise.
Can Any Payroll Company Handle Truck Driver Per Diem?
Not necessarily.
Many payroll companies process trucking payroll exactly like they process payroll for a dental office or retail business.
Truck driver payroll is different.
Drivers may be paid by:
- Mileage
- Percentage
- Hourly pay
- Load pay
- Salary
- Hybrid compensation methods
Per diem adds another layer of specialized knowledge.
When evaluating trucking payroll services, ask questions such as:
- How do you calculate qualifying days?
- How do you document per diem?
- How do you handle payroll records during an audit?
- How much trucking payroll experience does your team have?
If your payroll provider struggles to answer these questions, they may not specialize in payroll for trucking.
Common Mistakes Trucking Companies Make
The most common mistakes include:
- Paying per diem every day regardless of travel
- Failing to explain the program to drivers
- Assuming every driver automatically qualifies
- Working with payroll providers unfamiliar with trucking
- Not maintaining supporting documentation
Avoiding these mistakes allows companies to capture the financial benefits while remaining compliant.
Choosing the Right Trucking Payroll Services
If you’re evaluating trucking payroll services, per diem should be one of many questions you ask.
An experienced trucking payroll provider should also understand:
- Multi-state payroll
- Driver pay calculations
- Mileage pay
- Percentage pay
- California payroll rules
- Garnishments
- Fuel reimbursements
- Owner-operator settlements
- Payroll tax compliance
Payroll for trucking is significantly different from payroll in most other industries, and specialized expertise can help prevent costly mistakes.
Final Thoughts
Truck driver per diem doesn’t have to be complicated.
The rules are well established.
When implemented correctly:
- Drivers keep more of what they earn.
- Trucking companies reduce payroll-related costs.
- Everyone benefits.
The biggest risk isn’t using per diem.
It’s implementing it incorrectly or relying on payroll providers who don’t fully understand trucking payroll.
