Running a trucking business means dealing with many expenses. Food, lodging, and other costs add up fast when you are on the road. Per diem helps truck drivers and owner-operators handle these expenses better. Understanding how per diem work can save you money and reduce paperwork. This guide breaks down everything you need to know about per diem for the trucking industry.
What Does Per Diem Mean?
Per diem comes from Latin and means “for each day” or “by the day.” In trucking, per diem is a daily allowance that companies give to drivers to cover travel costs. These costs include meals, lodging, and other expenses while away from home.
The IRS sets standard rates each year to help businesses calculate fair reimbursements. For 2025, the standard per diem rate is $178 per day, according to the General Services Administration. Per diem makes life easier for truck drivers because you don’t need to save every single receipt. Instead, you get a fixed daily amount.
What Expenses Does Per Diem Cover?
Per diem covers three main types of expenses for truck drivers on the road. Understanding what qualifies helps you maximize your reimbursement and stay compliant with regulations.
Lodging Expenses
Lodging includes hotel rooms, motel stays, and short-term rentals while you’re away from home. These costs are usually the largest part of your per diem allowance.
Meal Expenses
Meals cover breakfast, lunch, dinner, and snacks throughout the day. You don’t need itemized receipts for each meal when using the standard per diem method.
Incidental Expenses
Incidental expenses include tips for hotel staff, laundry services, phone calls for business, and small personal items needed on the road. These minor costs add up quickly during long trips.
Per diem does NOT cover transportation costs like fuel, tolls, and vehicle maintenance. These are separate expenses that many truck dispatching services help drivers track separately for accurate accounting.
How Does Per Diem Work for Truck Drivers?
Per diem works through two main methods that trucking companies use to reimburse drivers for travel expenses.
Fixed-Rate Method
The fixed-rate method means you receive a set daily amount before or during your trip. The amount stays the same regardless of actual spending. If you spend less than the allowance, you can often keep the difference.
Actual Expense Method
The actual expense method requires you to pay for expenses out of pocket first. Then you submit receipts for reimbursement up to the per diem limit. Most trucking companies prefer the fixed-rate method because it’s simpler.
Who Gets Per Diem?
Several types of trucking professionals qualify for per diem reimbursement based on their work situation:
- Owner-operators traveling for business
- Company drivers on long hauls
- Freight haulers away from home overnight
Professional trucker accounting services can help you track per diem properly to ensure you claim all eligible expenses.
How Are Per Diem Rates Calculated?
The GSA updates rates every year on October 1st, and rates vary based on location and cost of living. Let me break down the different rate structures available.
Standard Per Diem Rate
The 2025 standard rate totals $178 per day. This breaks down into $110 for lodging and $68 for meals and incidentals.
High-Low Method
Some cities have higher rates than the standard because of increased costs. The high-low method simplifies this:
| Rate Type | Daily Amount | Lodging | Meals & Incidentals | Best For |
| Standard Rate | $178 | $110 | $68 | Most U.S. cities |
| High-Cost Rate | $319 | $233 | $86 | Major metro areas |
| Low-Cost Rate | $225 | $151 | $74 | Rural areas |
First and Last Day Rule
You only get 75% of the meal allowance on travel start and end days. This accounts for partial-day travel when you’re not on the road all day.
Trucking businesses often use IFTA reporting to track miles by state. This helps calculate accurate per diem rates for different locations.
Is Per Diem Taxable?
Good news for truck drivers! Per diem is usually not taxable income when you follow IRS guidelines correctly.
IRS Accountable Plan Requirements
The IRS treats per diem as reimbursement, not wages, but you must follow specific rules:
- Expenses must be business-related and necessary for your job
- You must report expenses within 60 days of incurring them
- You must return any excess money to your employer
When Per Diem Becomes Taxable
Per diem becomes taxable in certain situations that you need to avoid:
- You exceed federal rate limits
- You don’t provide expense reports on time
- Your company doesn’t follow IRS rules
Smart drivers use document management services to stay organized. This keeps all paperwork ready for tax time and prevents costly mistakes.
Benefits of Using Per Diem
Per diem offers many advantages for truckers that go beyond simple reimbursement. Here are the key benefits you’ll experience:
- Simpler record keeping with no need to save every receipt
- Better cash flow by knowing your daily budget upfront
- Tax savings that reduce taxable income legally
- Reduced stress from less administrative work
- Clear spending guidelines with no disputes over receipts
Best Practices for Per Diem Policies
Following best practices ensures your per diem system works smoothly and stays compliant with federal regulations.
- Set Clear Rules: Write down your per diem policy in detail. Explain what’s covered and what’s not, then share the policy with all drivers.
- Use Federal Guidelines: Base rates on GSA standards and update them annually. Adjust for high-cost areas when necessary to stay competitive.
- Keep Good Records: Track travel dates and locations carefully. Note business purposes and save supporting documents for at least three years.
- Review Regularly: Check if rates still make sense and adjust for inflation. Update policies as your business needs change throughout the year.
- Professional rate negotiation services can help ensure your per diem rates stay competitive. This keeps drivers happy and compliant with regulations.
- Plan for Special Cases: International trips need different rates from domestic travel. Long-term assignments may require adjustments, and seasonal changes affect costs in some areas.
How to Claim Per Diem
The claiming process is straightforward when you follow these steps and maintain good records.
Track Your Travel Days
Count each day away from home accurately. Note your location each night and record the business purpose of your trip.
Submit Your Claim
Fill out the expense report with dates and destinations included. Add any required documentation your company needs for processing.
Get Reimbursed
Receive payment that usually comes weekly or monthly. Check the amount matches your calculation and keep records for tax purposes.
Many trucking operations use factoring services alongside per diem. This ensures steady cash flow while waiting for payments.
Common Per Diem Mistakes to Avoid
Avoiding these common errors saves you money and prevents tax problems down the road.
- Not keeping records of travel dates and locations
- Exceeding federal limits that make excess taxable
- Missing the 60-day deadline for expense reports
- Forgetting the 75% rule for first and last travel days
Per Diem for Different Trucking Situations
Different types of trucking professionals handle per diem in unique ways based on their business structure.
Owner-Operators
Owner-operators have more flexibility with per diem than company drivers. You can set your own rates within IRS limits and adjust them based on actual routes. Keep detailed records because you’re responsible for your own tax reporting.
Company Drivers
Company drivers typically receive per diem as part of their compensation package. The company sets the rates and handles most paperwork. You still need to track your travel days and locations for verification.
New Authority Holders
New authority holders just starting their trucking business should establish per diem policies early. This creates professional habits and makes accounting easier from the start. Services for dispatch for new authority often include guidance on setting up proper per diem systems.
Conclusion
Understanding how does per diem work helps truck drivers manage expenses better and provides significant tax benefits. The fixed daily rates make budgeting easier for owner-operators and fleet managers while reducing paperwork stress.
Start by learning your eligibility and local rates from the GSA website. Set up a clear policy that follows IRS rules and keeps basic records of your travel for tax purposes.
