Truck Driver Per Diem FAQ: The Questions Drivers Ask Most (Answered)
Published: August 7th, 2026
Executive Summary
Truck driver per diem remains one of the most misunderstood topics in trucking. Many drivers worry that it is a trick, that it will hurt their retirement, or that it will make it harder to buy a house.
In reality, when a per diem program is designed correctly, it simply allows part of a driver’s taxable wages to be treated as a non-taxable reimbursement for travel expenses. The result is usually a larger weekly paycheck without increasing the company’s payroll costs.
This article answers the most common questions truck drivers ask about per diem, explains the tradeoffs honestly, and helps trucking companies better educate their drivers.

Why Do Drivers Have So Many Questions About Per Diem?
Most drivers don’t learn about per diem from payroll professionals.
They hear about it from another driver, read a Facebook post, or hear conflicting advice at a truck stop.
Unfortunately, every trucking company handles per diem differently. That creates confusion.
The good news is that once drivers understand how a properly designed program works, most of the fear disappears.
Let’s answer the questions drivers ask the most.
Is Truck Driver Per Diem Extra Money?
No.
With the type of per diem program we recommend, drivers are not receiving additional compensation.
Instead, part of their taxable wages is converted into a non-taxable reimbursement allowed under IRS rules.
That means:
- Gross taxable wages go down
- Taxes withheld go down
- Net take-home pay goes up
Drivers are simply keeping more of the money they already earned instead of sending it to taxes.
Some trucking companies do pay per diem as additional compensation, so drivers should always ask how their company’s program works.
Will Per Diem Reduce My Social Security Benefits?
Yes.
This is one tradeoff every driver should understand.
Because less Social Security tax is being paid during your working years, your future Social Security benefit will generally be lower.
That’s why trucking companies should explain this before enrolling drivers.
However, many drivers can come out significantly ahead by investing part of their weekly tax savings.
For example:
- Weekly tax savings: approximately $90-$100
- Invest only $25 per week into an IRA
- Keep the remaining savings in your paycheck
For many drivers, this strategy can produce more retirement savings than the reduction in future Social Security benefits.
Can W-2 Truck Drivers Still Deduct Per Diem on Their Tax Return?
No.
Since the Tax Cuts and Jobs Act changed the rules, W-2 drivers generally cannot deduct unreimbursed employee travel expenses.
However:
- W-2 drivers can still receive tax-free per diem from their employer.
- Owner-operators receiving Form 1099 may still qualify for per diem deductions if they meet IRS requirements.
Always discuss your individual tax situation with a qualified tax advisor.
Why Are My W-2 Wages Lower?
This is one of the biggest surprises for drivers.
Your taxable wages will usually be lower because some compensation has been reclassified as non-taxable per diem.
On your W-2 you’ll typically notice:
- Lower taxable wages in Boxes 1, 3, and 5
- Per diem reported separately in Box 12 with Code L
Lower taxable wages do not necessarily mean you earned less money.
In many cases, your weekly take-home pay actually increased.
Will Per Diem Affect Getting a Mortgage or Car Loan?
Sometimes.
Some lenders only review taxable wages shown on your W-2.
Others review:
- Bank statements
- Total deposits
- Employer verification letters
- Overall compensation
If you’re applying for financing:
- Tell the lender you receive per diem.
- Ask your payroll company for a letter explaining your compensation.
- Address the issue early instead of waiting until closing.
Good documentation often prevents unnecessary delays.
Do Drivers Receive Per Diem Every Day?
No.
Per diem only applies on qualifying travel days.
Generally, drivers qualify when:
- They are away from home overnight.
- They are subject to Hours of Service rules.
- They incur meal and incidental expenses while traveling.
Drivers who are home generally should not receive per diem for those days.
Receiving per diem every day of the year could indicate the program is being administered incorrectly.
Can I Opt Out of Per Diem?
Usually yes.
The employer ultimately determines how compensation programs are structured, but many trucking companies allow drivers to opt out.
Some drivers choose not to participate because:
- They are concerned about future Social Security.
- They are buying a home.
- They prefer higher taxable wages.
- They simply feel more comfortable without per diem.
A good employer should explain both the advantages and disadvantages and allow drivers to make an informed decision whenever possible.
How Much Money Can Truck Drivers Save?
Every driver’s situation is different.
Savings depend on:
- Mileage
- Pay rate
- Number of travel days
- State income taxes
- Federal withholding
- W-4 elections
For many over-the-road drivers, weekly savings often fall between:
- $90-$100 per week
- $4,500-$5,000 per year
That can make a meaningful difference for trucking families.
Many drivers use the additional money to:
- Pay bills
- Build emergency savings
- Contribute to retirement
- Support their families
The Biggest Mistake Isn’t Refusing Per Diem
The biggest problem isn’t that drivers refuse per diem.
The biggest problem is confusion.
Drivers deserve clear answers.
When trucking companies explain both the advantages and the tradeoffs honestly, drivers can make informed decisions instead of relying on rumors or misinformation.
Good communication builds trust, and trust helps retain drivers.
For companies looking to improve payroll for trucking, educating drivers about per diem is one of the simplest ways to reduce confusion and improve employee confidence.
