What could happen if you’re paying too much, not enough, or skipping it altogether?

In this article, you’ll learn what per diem really means for trucking, where most companies go wrong, and how to avoid mistakes that can cost you thousands.

Underpaying Per Diem

What Does Per Diem Mean for Trucking Payroll?

Per diem means “per day,” and in the trucking world, it’s part of a driver’s wage that helps cover daily expenses like meals and travel expenses when they’re away from home. If the driver qualifies, the IRS allows $80 for each day they are away from home.

That means this part of a driver’s income isn’t taxed, helping drivers take home more money and saving the company on payroll taxes.

It’s a smart benefit when handled correctly.But here’s the catch… if per diem isn’t calculated correctly, it can backfire in a big way.

Overpaying Per Diem

3 Common Per Diem Mistakes That Put Trucking Companies at Risk

A lot of trucking companies think they’re handling per diem the right way — but they’re actually opening themselves up to risk.

Here’s where things go off track:

Mistake #1: Not Offering Per Diem at All

Some companies don’t offer per diem. That’s a missed opportunity.

Without it, drivers pay more in taxes, take home less, and may go elsewhere for better pay. Plus, the company pays more in payroll taxes than it needs to.

Mistake #2: Paying Per Diem Per Mile or as a Percentage

Other companies try to calculate per diem based on miles driven or a percentage of wages.
Sounds simple, right? But here’s the problem:

If you overpay per diem — meaning you give more than the IRS allows — you lower the driver’s taxable wage too much.

That triggers a red flag with the IRS.

And that can lead to audits, back taxes, penalties, and a big mess.

Mistake #3: Missing Records or No Clear System

Even if you’re using the correct daily rate, if you don’t document everything properly, you could still be in trouble during an audit.

What Happens When You Overpay Per Diem in Trucking?

Let’s be clear: overpaying per diem can be worse than not paying it at all.

Why? Because when you overpay per diem, you’re lowering the driver’s reported income too much, and not paying enough tax on the wages.

This means:

Less Social Security and Medicare paid in.

Less unemployment insurance coverage.

A wage report that doesn’t match reality.

The IRS sees that as intentional underreporting of income, and they don’t take that lightly.

IRS Penalties and Payroll Problems from Per Diem Mistakes

Here’s what can happen if you’re not careful with per diem:

IRS Audits for Per Diem Errors
They’ll want to see how you calculated per diem, and if your records are incomplete or off, you could owe money.

Back Taxes and Payroll Adjustments
If you overpaid, you’ll owe payroll taxes on the difference.

Penalties, Interest, and Financial Strain
These add up fast and can seriously hurt your bottom line.

Frustrated Drivers and Staff Turnover
If a driver’s wages or tax records get messed up, it could lead to complaints or even turnover.

How to Calculate Per Diem the IRS-Approved Way

The IRS allows you to reimburse drivers per diem using a daily rate, and this is the method they prefer.

To keep it safe and simple:

Use the standard IRS daily rate.

Keep detailed records of each day a driver qualifies.

Apply the rules fairly and consistently across all drivers.

That’s how you stay compliant — and keep both your drivers and Uncle Sam happy.
