O TruckingMileage vs Actual Expense for Truckers
Key Takeaways
- A semi truck exceeds the 6,000-lb GVWR limit, so the standard mileage rate cannot be used on the rig itself — owner-operators deduct real costs with the actual expense method.
- Actual costs for an owner-operator typically run $1.50–$2.50+ per mile, far above the 2025 standard rate of 70 cents per mile.
- The standard mileage rate still applies to a personal vehicle used for business errands (terminal, parts, accountant), so track those miles separately.
- Claiming Section 179 or MACRS depreciation in the first year locks you into actual expenses for that vehicle for as long as you own it.
- Per diem, tolls, and parking are deducted on top of either method — they are not replaced by your vehicle deduction.

Two Methods, Two Very Different Outcomes
The IRS gives self-employed drivers two ways to deduct vehicle expenses on Schedule C: the standard mileage rate and the actual expense method. Each has different rules, different record-keeping requirements, and produces very different deduction amounts—especially for owner operators running heavy commercial vehicles.
Here's the key thing most truckers need to know upfront: the standard mileage rate is designed for passenger vehicles and light-duty trucks. If you're running a Class 7 or Class 8 truck (most semis), the standard mileage rate generally doesn't apply to your rig—but it can apply to a personal vehicle you use for business purposes. Almost every owner operator uses the actual expense method for their truck. For the full list of write-offs that ride alongside this choice, see our owner operator tax deductions guide and the breakdown of typical owner operator costs.
Important Distinction: Truck vs Personal Vehicle
Standard Mileage Rate Explained
The standard mileage rate is a flat per-mile deduction set by the IRS each year. For 2025, it's 70 cents per mile (up from 67 cents in 2024), and for 2026 it rises to 72.5 cents per mile. The official rate is announced each December in an IRS news release.

When the Standard Mileage Rate Makes Sense for Truckers
Actual Expense Method Explained
The actual expense method requires you to track and deduct every real expense associated with operating your truck. This is the method used by virtually all owner operators for their commercial vehicles, and it typically produces a much larger deduction than the standard mileage rate ever could.
What You Can Deduct with Actual Expenses
| Expense Category | Typical Annual Cost |
|---|---|
| Fuel (diesel) | $45,000 - $75,000 |
| Truck depreciation | $15,000 - $40,000 |
| Insurance | $14,000 - $22,000 |
| Maintenance & repairs | $9,600 - $18,000 |
| Truck loan interest | $3,000 - $12,000 |
| Permits & registration | $2,400 - $4,800 |
| Tolls | $2,000 - $5,000 |
| Parking | $500 - $2,000 |
| Total Actual Expenses | $91,500 - $178,800 |
Compare that total to what you'd get with the standard mileage rate on 120,000 business miles: 120,000 x $0.70 = $84,000. The actual expense method wins by $7,500 to $94,800 in this example—and that gap grows with truck age, fuel consumption, and insurance costs.
Depreciation Is the Big Lever
If you buy a truck and it qualifies for Section 179 expensing, you can deduct the entire purchase price in the first year (up to $1,220,000 for 2024). On a $120,000 used truck, that's a $120,000 deduction in year one. No mileage rate will ever come close to that. This is why your first-year election matters so much. See our Section 179 truck deduction guide for current-year limits and how to elect it on your return.
Calculation Comparison: A Typical Owner Operator
Let's compare both methods for a typical owner operator running a paid-off dry van pulling 120,000 business miles per year. Even though the standard mileage rate technically doesn't apply to semi trucks (GVWR over 6,000 lbs), this comparison illustrates why actual expenses are always preferable.

Actual Expense Advantage: $31,200 More in Deductions
At a combined 25% marginal tax rate (income + SE tax), that extra $31,200 in deductions saves this owner operator approximately $7,800 in taxes. And this is a moderate example—drivers with newer trucks using Section 179 or those with high fuel costs see even bigger gaps.
Actual Expense Method: Pros & Cons for Truckers
Actual Expense Method — Pros
- +Captures real per-mile costs of $1.50–$2.50+, far exceeding the standard mileage rate.
- +Lets you claim Section 179 or MACRS depreciation to write off most or all of a truck's cost.
- +Required and allowed for semi trucks over 6,000 lbs GVWR, where the mileage rate does not apply.
- +Available whether you own, finance, or lease your truck (lease payments are deductible).
Actual Expense Method — Cons
- −Requires detailed record-keeping — every fuel, repair, insurance, permit, and toll receipt.
- −Claiming MACRS or Section 179 in year one locks you out of the standard mileage rate on that truck for good.
- −More complex to calculate, especially when you must apply a business-use percentage.
Year-One Section 179 Example
Can You Switch Between Methods?
The ability to switch depends entirely on what you chose in the first year you used the vehicle for business. Per IRS Publication 463, here are the rules:
Started with Standard Mileage? You Can Switch.
If you used the standard mileage rate in the first year, you can switch to the actual expense method in any later year. However, when you switch, you must use straight-line depreciation for the remaining useful life of the vehicle (not MACRS or Section 179).
Started with Actual Expenses (MACRS)? You're Locked In.
If you claimed MACRS depreciation or Section 179 expensing in the first year, you cannot switch to the standard mileage rate for that vehicle, ever. You must use actual expenses for the entire time you own the vehicle. This lock-in applies to the specific vehicle, not to your business overall.
This Rarely Matters for Semi Trucks
First-Year Rules & the Election That Locks You In
Your first-year election is the most important tax decision you make for each vehicle. Here's what you need to know about the rules:
Section 179 / Bonus Depreciation
In the first year of business use, you can deduct the entire cost of the vehicle using Section 179 (up to $2,500,000 for 2025-2026) or bonus depreciation (restored to 100% for qualifying property under the 2025 OBBBA law). This is a massive first-year deduction that no mileage rate can match. Once you claim this, you're locked into actual expenses for that vehicle.
MACRS Depreciation Schedule
If you don't take Section 179, commercial trucks are typically depreciated over 5 years using MACRS (Modified Accelerated Cost Recovery System). Year 1: 20%, Year 2: 32%, Year 3: 19.2%, Year 4: 11.52%, Year 5: 11.52%, Year 6: 5.76%. This accelerated schedule front-loads your deductions. Using MACRS also locks you into actual expenses.
Standard Mileage in Year One
If eligible and you use the standard mileage rate in year one, the IRS considers depreciation to be included at a rate of about 28-30 cents per mile (the IRS publishes this component each year). This preserves your ability to switch to actual expenses in later years, but with straight-line depreciation only.
Talk to Your CPA Before Your First Tax Filing
Record-Keeping Requirements
The IRS requires “adequate records” for both methods, but the actual expense method demands significantly more documentation. Here's what you need for each:
Standard Mileage Rate Records
- Mileage log (date, destination, business purpose, miles)
- Odometer readings at start and end of year
- Toll and parking receipts
- Loan interest documentation (if claiming separately)
Actual Expense Method Records
- Every fuel receipt (or fuel card statements)
- All maintenance and repair invoices
- Insurance premium statements
- Depreciation schedule (purchase price, date, method)
- Loan statements showing interest paid
- Toll, parking, and permit receipts
- Mileage log for business use percentage
- Registration and title documents
Digital Record-Keeping Saves You
Business Use Percentage
If you use a vehicle for both business and personal purposes, you can only deduct the business-use portion of your expenses. For dedicated commercial trucks, this is typically 90-100% business use. For a personal vehicle used partly for business, you need to calculate the percentage.
Business Use Calculation Example
Multiply total actual expenses by 92.3% to get your deductible amount.
For owner operators whose truck is used exclusively for hauling freight, the business use percentage is generally 100%. The only exception is if you drive the truck for personal errands—running to the grocery store in your semi counts as personal use. Commuting from home to your terminal is also personal use unless your home is your tax home and principal place of business.
Commuting Miles Are NOT Business Miles
Frequently Asked Questions
What is the standard mileage rate for truckers in 2025 and 2026?
The IRS standard mileage rate is 70 cents per mile for 2025 and 72.5 cents per mile for 2026 for business use. This rate is updated annually and covers gas, depreciation, insurance, maintenance, and general wear and tear. Note that heavy trucks generally cannot use it — it applies to a personal vehicle used for business.
Can owner operators use the standard mileage rate?
Generally, no for semi trucks. The standard mileage rate is only available for vehicles under 6,000 lbs GVWR, which excludes nearly all commercial trucks. However, if you use a personal vehicle for business purposes (driving to meetings, picking up parts), you can claim the standard mileage rate on that vehicle.
Which method saves owner operators more money?
The actual expense method almost always saves more money for owner operators. With fuel costs of $45,000-$75,000/year, insurance at $14,000-$22,000, maintenance at $9,600-$18,000, and depreciation on a $100,000+ truck, actual expenses typically total $1.50-$2.50+ per mile. The standard mileage rate of $0.70/mile doesn't come close.
Can I switch between the mileage and actual expense methods?
It depends on your first-year choice. If you used the standard mileage rate in the first year, you can switch to actual expenses in any later year (but must use straight-line depreciation). If you used actual expenses with MACRS depreciation in the first year, you are locked into actual expenses for the life of that vehicle.
What records do I need for the actual expense method?
You need receipts for every deductible expense (fuel, maintenance, repairs, insurance, tolls), a mileage log showing total miles and business miles, documentation of business use percentage, depreciation schedules, and records of any improvements. Use a dedicated business credit card and keep digital copies of all receipts. The IRS can audit up to 3 years back (6 years if they suspect underreporting).
Does the standard mileage rate include fuel costs?
Yes, the standard mileage rate includes fuel, oil, depreciation, insurance, registration, and general maintenance. If you use this rate, you cannot separately deduct these expenses. You can still deduct parking fees, tolls, and vehicle loan interest separately even when using the standard mileage rate.
Is per diem separate from the mileage or actual expense method?
Yes. The per diem (meals and incidental expenses) deduction is completely separate from how you deduct your truck—it's claimed in addition to your actual truck expenses, not instead of them. Drivers subject to DOT hours-of-service rules can deduct 80% of the federal per diem rate for each day away from their tax home, on top of fuel, depreciation, insurance, and maintenance. See our per diem deduction guide for the current rate.
Can I use the actual expense method if I lease my truck?
Yes. Lease operators and drivers with a leased or financed truck still use the actual expense method. Your lease payments are deductible (the luxury-auto lease limits do not apply to heavy commercial trucks), along with fuel, maintenance, insurance, tolls, and permits. You cannot claim depreciation or Section 179 on a vehicle you lease rather than own, but the lease payment itself replaces that deduction.
Can W-2 truck drivers use either deduction method?
No, not on federal returns. Since the 2018 Tax Cuts and Jobs Act, W-2 employees cannot deduct unreimbursed business expenses including mileage or actual vehicle expenses on their federal tax return. Some states still allow the deduction on state returns. Only self-employed (1099) truck drivers can claim either method on their Schedule C.
Common Mistakes Truckers Make With Vehicle Deductions
- Forgetting to track business miles on a personal vehicle — an easy deduction many truckers miss entirely.
- Counting commuting miles (home to terminal) as business miles — those are personal use.
- Trying to claim the standard mileage rate and separately deduct fuel or depreciation — the rate already includes them.
- Skipping the per diem deduction because you assume it is covered by truck expenses — it is claimed separately.
- Not keeping receipts long enough — the IRS can audit 3 years back, or 6 if it suspects underreporting.
The Bottom Line
For owner operators running commercial trucks, the actual expense method is the clear winner. Your truck exceeds the GVWR limit for the standard mileage rate, and even if it didn't, your actual expenses per mile far exceed the IRS rate. Track every expense, keep organized records, and work with a CPA who understands trucking deductions.
The one place the standard mileage rate matters is your personal vehicle. If you drive your car for any business purpose, track those miles separately—it's an easy deduction that many truckers overlook. And remember: the first year you use any vehicle for business, your depreciation choice may lock you in for the life of that vehicle. Get advice before filing.
Vehicle expenses are only part of the picture. Pair this with the per diem deduction for truckers and the trucker home office deduction to capture every dollar you're entitled to.
