Tax Guide for Truck Drivers: Per Diem, Mileage, Deductions

Tax information in this article on tax guide for truck drivers: per diem, mileage, deductions is for educational purposes only and does not constitute tax, legal, or financial advice. Tax laws change, and individual circumstances vary. Consult a qualified tax professional or CPA for guidance specific to your situation.

Truck drivers — whether owner-operators running their own rigs or company drivers hauling for a carrier — have one of the most distinctive tax situations of any profession. The combination of per diem meal deductions, vehicle depreciation, fuel expenses, and the difference between W-2 and 1099 classification creates a tax landscape that rewards careful planning and punishes sloppy record-keeping.

This guide covers the tax rules that apply to truck drivers at every level: company drivers who receive W-2s, owner-operators filing Schedule C, and lease-operators who fall somewhere in between.

Company Driver vs. Owner-Operator: The Tax Divide

The most fundamental tax question for any truck driver is: Are you a W-2 employee or a self-employed independent contractor?

Factor	Company Driver (W-2)	Owner-Operator (1099)
Tax form received	W-2	1099-NEC
Income reported on	Form 1040 (wages)	Schedule C
Self-employment tax	No (employer pays half of FICA)	Yes (15.3% on net earnings)
Business deductions	Not available (TCJA suspension)	Fully deductible on Schedule C
Per diem deduction	Only if employer pays under accountable plan	Deductible on Schedule C
Mileage/truck expenses	Not deductible	Deductible on Schedule C
Estimated tax payments	Employer withholds	Must pay quarterly

The Lease-Operator Gray Area

Many drivers operate under a lease agreement with a carrier — they lease a truck from the company, haul exclusively for that carrier, and receive 1099 income. The IRS scrutinizes these arrangements closely. If the carrier controls how, when, and where you drive, you may actually be an employee regardless of what the contract says. Misclassification can result in back taxes, penalties, and lost deductions.

Per Diem for Truck Drivers

The per diem deduction is the single most valuable tax benefit for truck drivers. When you are away from your tax home overnight for work, you can deduct meal expenses using the IRS per diem rates instead of tracking actual receipts.

Per Diem Rates for Transportation Workers

Truck drivers classified as transportation industry workers (subject to DOT hours-of-service rules) use special per diem rates:

Location	2026 M&IE Rate (Projected)
CONUS (Continental US)	~$69/day
OCONUS (Outside CONUS)	Varies by location
High-cost areas	Up to ~$79/day
Partial days (first/last day)	75% of applicable rate

Who Can Claim Per Diem

Owner-operators: Deduct per diem on Schedule C. This is the most straightforward path.
Company drivers: Can only benefit if their employer provides per diem under an accountable plan (excluded from income). Company drivers cannot independently deduct per diem under current law because unreimbursed employee expenses are suspended.
Lease-operators: If truly self-employed (1099), deduct on Schedule C. If misclassified, treat as company driver.

Calculating Your Per Diem Deduction

The deduction is based on the number of qualifying days — days you are away from your tax home overnight for work purposes.

Example: An owner-operator is on the road 280 days in 2026.

280 days x ~$69/day = ~$19,320 in meal per diem
Meal deductions for transportation workers are currently deductible at 80% (special rate for DOT-covered workers, compared to the standard 50% for other taxpayers)
Deductible amount: $19,320 x 80% = **$15,456**

This deduction alone can reduce your taxable income by over $15,000 — and you do not need a single meal receipt. You just need a log of your travel days.

Mileage and Vehicle Expenses

Owner-operators have two methods for deducting vehicle expenses:

Actual Expense Method

Track all actual costs of operating your truck:

Expense Category	Examples
Fuel	Diesel, DEF fluid
Maintenance and repairs	Oil changes, tires, brake jobs, engine work
Insurance	Commercial truck insurance, cargo insurance
Depreciation	Annual depreciation of your truck (see below)
Lease payments	If leasing your truck
Permits and fees	IFTA, IRP, oversize/overweight permits, highway use tax (Form 2290)
Tolls and parking	All tolls and truck parking fees
Truck washes	Exterior and interior cleaning
Communication	CB radio, ELD device, cell phone (business use portion)

Standard Mileage Rate

The IRS standard mileage rate for 2026 is projected at ~$0.70/mile for business use. However, this rate is generally intended for cars and light vehicles. Most owner-operators with heavy trucks find the actual expense method produces a significantly larger deduction because of the high cost of diesel, tires, and depreciation on a $150,000+ truck.

Important: Once you use the actual expense method for a vehicle, you generally cannot switch to the standard mileage rate for that vehicle in future years. Most trucking tax professionals recommend actual expenses for semi-trucks.

Truck Depreciation: Section 179 and MACRS

Your truck is likely your largest capital investment, and depreciation is one of your largest deductions.

Section 179 Expensing

Under Section 179, you can deduct the full cost of a qualifying truck in the year you place it in service, up to the annual limit of ~$1,250,000 (2026 projected). For most owner-operators, this means you can write off the entire purchase price of a truck in year one.

Bonus Depreciation

If Section 179 does not cover the full cost (unlikely for a single truck), bonus depreciation allows an additional first-year deduction. The bonus depreciation rate has been phasing down:

Year	Bonus Depreciation Rate
2022	100%
2023	80%
2024	60%
2025	40%
2026	~20%
2027	0% (unless extended)

MACRS Depreciation

If you do not use Section 179 or bonus depreciation, trucks are depreciated over 5 years (for heavy trucks over 13,000 lbs GVWR) using MACRS. Trailers are typically 5-year property as well.

Planning note: Taking the full Section 179 deduction in year one creates a large deduction immediately but leaves nothing to deduct in future years. If your income is steady, spreading depreciation over 5 years may produce a better long-term tax result. Consult your tax professional.

Self-Employment Tax for Owner-Operators

Owner-operators owe self-employment tax on their net Schedule C income. The SE tax rate is 15.3% (12.4% Social Security + 2.9% Medicare) on 92.35% of net self-employment earnings.

SE Tax Calculation Example

Item	Amount
Gross 1099 income	~$200,000
Schedule C deductions (fuel, maintenance, depreciation, per diem, insurance, etc.)	~($120,000)
Net Schedule C income	~$80,000
SE tax base (92.35%)	~$73,880
SE tax (15.3%)	~$11,304
Deductible half of SE tax (above the line)	~$5,652

The employer-equivalent half of SE tax (~$5,652) is deductible on your Form 1040, reducing your adjusted gross income. Report SE tax on Schedule SE.

Quarterly Estimated Taxes

Owner-operators must make quarterly estimated tax payments because no employer withholds taxes from their 1099 income. Payments are due:

Quarter	Deadline
Q1 (Jan–Mar)	April 15
Q2 (Apr–May)	June 15
Q3 (Jun–Aug)	September 15
Q4 (Sep–Dec)	January 15 (following year)

How much to pay: Estimate your annual tax liability (income tax + SE tax) and divide by 4. Most trucking tax professionals recommend paying at least 100% of your prior year’s tax (or 110% if AGI exceeded ~$150,000) to avoid underpayment penalties.

Record-Keeping Requirements

The IRS expects truck drivers to maintain thorough records. At minimum, keep:

Daily Log

Date, starting location, ending location
Total miles driven (business vs. personal)
Whether you were away from home overnight (for per diem)

Expense Records

Fuel receipts (or fuel card statements)
Maintenance and repair invoices
Insurance premium statements
Truck payment or lease payment records
Toll receipts
Permit and license fees

Digital Tools

Many owner-operators use fleet management software, ELD data, and fuel card reports to automate record-keeping. The IRS accepts electronic records — just ensure they are backed up and accessible if audited.

Other Deductible Expenses

Beyond the major categories, owner-operators can deduct:

Health insurance premiums: Self-employed health insurance deduction (above the line) for medical, dental, and vision premiums for yourself, your spouse, and dependents
Retirement contributions: SEP IRA (up to 25% of net SE income), Solo 401(k), or Traditional IRA — reduces both income tax and potentially your tax bracket
Dog/pet expenses: If you carry a guard dog for cargo security, related expenses (food, vet care) may be deductible as a business expense — keep documentation of the business purpose
Lumper fees: Fees paid for loading/unloading services
Scales and weigh station costs
Sleep accessories: Sleeping bags, bedding for the sleeper cab (if used exclusively for overnight work)
Home office deduction: If you use a dedicated space at home for dispatching, bookkeeping, and trip planning

Frequently Asked Questions

What is the trucker per diem rate for 2026?

The CONUS per diem rate for meals and incidentals is projected at ~$69/day for standard locations. Transportation workers subject to DOT hours-of-service rules can deduct this at 80% (rather than the standard 50%), making the effective deduction ~$55.20/day.

Can company drivers deduct per diem?

Not on their own tax return under current law. The unreimbursed employee expense deduction is suspended. However, if your employer provides per diem under an accountable plan, that amount is excluded from your taxable income on your W-2 — achieving the same economic result.

Should I use the standard mileage rate or actual expenses?

For semi-trucks and heavy vehicles, actual expenses almost always produce a larger deduction due to high fuel, maintenance, and depreciation costs. The standard mileage rate (~$0.70/mile) is designed for lighter passenger vehicles.

How much should I set aside for taxes?

A common rule of thumb for owner-operators is to set aside 25-30% of gross income for taxes (federal income tax + SE tax + state income tax). Your actual rate depends on your deductions and tax bracket.

Can I deduct my CDL training costs?

If you obtained your CDL to enter the trucking profession, the training cost is generally not deductible (it qualifies you for a new trade or business). However, if you pay for additional endorsements or refresher training to maintain your existing CDL, those costs are deductible for self-employed drivers.

Do I need to file in every state I drive through?

It depends on the state. Some states require nonresident returns if you earn income there; others have de minimis rules or reciprocity agreements. Your IFTA filing covers fuel tax, but income tax is separate. Consult a tax professional familiar with multi-state trucking.
