Owner Operator Tax Write-Offs: The Complete 2026 List
Most owner-operators leave $8,000–$15,000 in deductions on the table every year — not because the expenses don't exist, but because they don't know what's deductible or what documentation the IRS requires. This is the complete list.

2026 figures: Deduction categories, per diem rates, and depreciation rules reflect IRS guidance for tax year 2026. Consult a CPA for your specific situation — this guide covers the rules, not advice for your return.
01 Who Qualifies and How Deductions Work
As an owner-operator, you're self-employed — which means you file a Schedule C (or as an LLC/S-Corp) and deduct ordinary and necessary business expenses before calculating taxable income. Unlike a company driver who gets a W-2 and can no longer deduct unreimbursed employee expenses, every dollar you spend to operate your truck is potentially deductible.
The IRS requires two things for a business expense to be deductible: it must be ordinary (common in your industry) and necessary (appropriate and helpful for your business). Trucking expenses pass that test almost universally. The real risk isn't categorization — it's documentation. The IRS can disallow any deduction you can't substantiate with records.
What "deductible" means in dollars: If you're in the 22% tax bracket and take $10,000 in legitimate deductions, that's $2,200 back in your pocket — real money that's legally yours. Every category below is money the IRS says you don't have to pay taxes on.
The SE tax hit — and why deductions matter more for owner-operators
Company drivers pay only half of FICA taxes (employer covers the other half). You pay both sides — 15.3% on net self-employment income, plus income tax on top of that. At a $80,000 net profit, that's over $11,000 in SE tax before a dollar of income tax. Every $1,000 in deductions reduces your SE tax by $153 on top of your income tax savings. The math favors aggressive-but-legitimate deduction tracking.
02 Fuel Expenses
⛽
Diesel fuel purchases
Your single largest deductible operating cost
100% Deductible
All diesel purchased for your commercial truck is fully deductible. This includes fuel bought in any state — even when you cross state lines and pay varying fuel tax rates. The total cost of fuel (price + embedded fuel tax) is your deductible expense. Fuel card purchases from fleet networks (Comdata, EFS, TCS) are fully deductible; keep the receipts or download the transaction detail from your portal.
Docs needed: Fuel receipts or fuel card statements showing date, gallons, total cost, and location. Keep for 3 years minimum (4 if you have IFTA audit exposure).
Typical annual amount: $25,000–$60,000 depending on miles and route
🔋
DEF fluid & additives
Diesel exhaust fluid, fuel additives, anti-gel
100% Deductible
DEF fluid is a required operating cost for any 2010+ emissions-compliant diesel engine. Anti-gel additives, fuel stabilizers, and injector cleaners used for your truck are also fully deductible operating expenses. Same documentation standard as fuel.
Docs needed: Receipts from truck stops or suppliers. Keep with fuel records.
Typical annual amount: $500–$1,500
The IFTA filing guide covers how fuel purchases interact with your quarterly fuel tax return — understanding both together is how you maximize the tax benefit of every gallon you buy.
03 Truck Purchase & Depreciation
Your truck is your biggest capital expense — and it comes with some of the most powerful deductions in the tax code if you know how to use them.
🚛
Section 179 expensing
Deduct the full purchase price in year one
Up to 100% Year 1
Section 179 lets you deduct the full cost of a business vehicle in the year you place it in service — instead of depreciating it over 5 years. For 2026, the Section 179 deduction limit is approximately $1.22 million (adjusted for inflation). A $120,000 truck purchased and put in service in 2026 can be fully deducted in 2026, reducing your taxable income by $120,000 in a single year. The catch: your Section 179 deduction can't exceed your net business income for the year.
Docs needed: Bill of sale, financing agreement, date placed in service, Form 4562 on your tax return. Must be used more than 50% for business.
Potential deduction: Full purchase price, up to ~$1.22M
📉
Bonus depreciation
Deduct a percentage on top of or instead of Section 179
40% in 2025 / Phasing
Bonus depreciation allows you to immediately deduct a percentage of the asset's cost. It was 100% through 2022, then phased down: 80% in 2023, 60% in 2024, 40% in 2025. For assets placed in service in 2026, the rate will be 20%. This is separate from Section 179 and applies to new and used property. For most owner-operators, Section 179 is more advantageous — use bonus depreciation when you've already maxed Section 179 or need to create a loss.
Docs needed: Same as Section 179 — Form 4562, date placed in service, proof of business use percentage.
2026 rate: 20% of asset cost in year one
📆
Standard MACRS depreciation
5-year recovery period for commercial trucks
Over 5 Years
If you don't use Section 179 or bonus depreciation, your truck depreciates on a 5-year MACRS schedule (typically: 20% / 32% / 19.2% / 11.52% / 11.52% / 5.76% of cost). This is the conservative approach — it spreads deductions across years rather than front-loading them. Useful if you expect higher income in future years and want to preserve deductions.
Docs needed: Purchase documents, Form 4562. Track separately from lease payments.
Total depreciation: Full purchase price over 5 years (same dollars, different timing)
📋
Lease payments
Operating lease vs. finance lease — different treatment
100% (Operating Lease)
If you're on an operating lease (you don't own the truck at lease end), the entire lease payment is deductible as a business expense. Finance leases (with a purchase option) are treated more like ownership — you deduct the interest portion and depreciate the truck. Lease-operator agreements where the carrier holds title are a different structure — consult a CPA to confirm your treatment. The IRS looks at economic substance, not just the contract label.
Docs needed: Lease agreement, payment records. Note the lease type (operating vs. finance) for your preparer.
Typical annual lease cost: $24,000–$48,000
💳
Loan interest
The interest portion of truck loan payments
100% Deductible
If you financed your truck, the interest you pay is fully deductible as a business interest expense. The principal payment is not deductible — that's recovered through depreciation. Your lender's annual Form 1098 or year-end statement shows total interest paid for the year.
Docs needed: Loan statements or Form 1098, amortization schedule to separate principal from interest.
Typical annual interest: $3,000–$12,000 depending on loan balance and rate
04 Maintenance, Repairs & Tires
🔧
Repairs & mechanical work
Engine, transmission, brakes, electrical, air system
100% Deductible
All repair costs to maintain your truck in operating condition are fully deductible. This includes labor and parts for engine repairs, brake jobs, transmission work, air system repairs, electrical issues, DPF/EGR work, and any other maintenance that restores the truck to working order without extending its useful life. If a repair significantly improves the truck beyond its original condition (engine rebuild, major overhaul), it may need to be capitalized and depreciated — the threshold is roughly $2,500 per item under the IRS safe harbor.
Docs needed: Shop invoices showing work performed, parts list, and labor breakdown. Keep the invoice — a bank statement alone won't satisfy an auditor.
Typical annual amount: $5,000–$20,000 depending on truck age
🛞
Tires
New tires, retreads, tire repair, tire chains
100% Deductible
Tires are a consumable operating expense — fully deductible when purchased. This includes new steer, drive, and trailer tires; retreads; tire repair (plugs, patches); valve stems; and tire chains. Most owner-operators go through a full set of drives every 18–24 months at $3,000–$5,000. Every dollar is deductible. Tire roadside service and roadside assistance plans are also deductible operating expenses.
Docs needed: Purchase receipts or invoices from tire shops. Note the truck they were purchased for.
Typical annual amount: $3,000–$8,000
🛢️
Routine maintenance supplies
Oil, filters, fluids, wiper blades, lights
100% Deductible
All consumables used in operating and maintaining your truck are deductible: engine oil, oil filters, air filters, fuel filters, coolant, transmission fluid, gear lube, wiper blades, light bulbs, fuses, and similar items. If you do your own maintenance, parts are deductible at cost. Your labor for your own truck is not deductible (you can't pay yourself a deductible wage), but the parts are still fully deductible.
Docs needed: Receipts from parts stores or truck stops. A business credit card simplifies recordkeeping significantly.
Typical annual amount: $1,500–$4,000
Tracking maintenance costs accurately is also how you calculate your true cost per mile — which is the number that tells you whether any given load is actually profitable before you accept it.
Track Every Deductible Expense Automatically
NetMile's Tax Tracker captures receipts, categorizes expenses, and keeps your records audit-ready — so you never lose a deduction you've already paid for.
All premiums paid for commercial trucking insurance are fully deductible: primary liability (required by FMCSA), physical damage, bobtail insurance, non-trucking liability, and any riders. If you pay annually, the full premium is deductible in the year paid (cash basis). If your carrier fronts insurance and deducts it from settlements, those deductions reduce your gross income — don't double-count them.
Docs needed: Insurance policy declarations page, payment receipts or bank statements showing premium payments.
Typical annual premiums: $8,000–$18,000 depending on coverage and driving record
📦
Cargo insurance
Coverage for the freight you're hauling
100% Deductible
Cargo insurance premiums — whether you pay them directly or through a carrier program — are fully deductible. If you're required to carry cargo insurance by shipper contracts, that premium is an ordinary and necessary business expense regardless of whether you ever file a claim.
Docs needed: Policy documents, premium invoices or payment records.
Typical annual premium: $1,500–$4,000
🏥
Health insurance premiums
Self-employed health insurance deduction (Schedule 1)
100% Above-the-Line
Self-employed owner-operators can deduct 100% of health insurance premiums paid for themselves, their spouse, and dependents — as an adjustment to income on Schedule 1, not as a business expense on Schedule C. This is one of the most valuable deductions available and reduces your adjusted gross income directly. You cannot take this deduction if you were eligible for employer-sponsored coverage through a spouse's employer for any month during the year.
Docs needed: Insurance premium statements, 1095-A (marketplace) or premium payment records. Report on Schedule 1 Form 1040, not Schedule C.
Typical annual premium: $4,000–$12,000 (deduction matches what you pay)
06 Per Diem & Meals
Per diem is where many owner-operators either overclaim or underclaim. The rules are specific for DOT-regulated drivers — and more favorable than the standard business meal deduction most self-employed people use.
🍽️
DOT per diem (transportation workers)
Special rate for drivers subject to HOS regulations
80% Deductible
Owner-operators subject to DOT Hours of Service regulations can use the special transportation worker per diem rate — rather than tracking actual meal receipts. This is a fixed daily allowance the IRS allows as a proxy for actual meals and incidentals while away from home overnight. You don't need meal receipts when using the per diem method — your logbook establishes the days. The per diem is 80% deductible (not 50% like standard business meals), making this a better deal for most OTR drivers.
Docs needed: ELD or paper logbook records showing days away from home. No meal receipts needed when using per diem method.
Calculation: Days away × $80 × 80% = annual deduction

250 days out × $80/day × 80% = $16,000 in deductions. An OTR driver spending most of the year on the road can deduct $16,000 in per diem without a single meal receipt. That's $3,520 in tax savings at the 22% bracket — just from tracking your logbook days.
You must be away from your tax home overnight (or for a period requiring sleep or rest) to claim per diem. A local driver who returns home every night generally doesn't qualify. Your logbook is the primary substantiation document — the IRS accepts ELD records as equivalent to a paper log for per diem purposes.
07 Tolls, Scales & Parking
🛣️
Tolls
Highway, bridge, and tunnel tolls paid in business operation
100% Deductible
All tolls paid while operating your truck are fully deductible — including EZPass/PrePass transponder fees and account replenishments, cash tolls, and bridge/tunnel fees. Your EZPass account's annual statement shows the total paid; keep it for your records. If your carrier reimburses tolls, the reimbursement is income and the toll is still a deductible expense — they net out to zero tax effect, but both must be reported correctly.
Docs needed: EZPass/transponder account statements (annual), cash toll receipts if issued. Many EZPass portals export to PDF for the full year.
Typical annual amount: $2,000–$8,000 for heavy-toll corridors (Northeast, CA)
⚖️
Scale fees & weigh station charges
CAT scale, portable scales, weigh station fees
100% Deductible
CAT Scale fees and any weigh station charges paid in the course of operating your truck are fully deductible. The CAT Scale receipt from a truck stop is a valid business expense receipt — keep them or download your CAT Scale account history if you use the app.
Docs needed: Receipts, CAT Scale account history, or fuel stop records that include scale charges.
Paid parking for your truck during business operations is fully deductible. This includes truck stop overnight parking fees, secure parking facilities, reserved lot fees, and any other paid parking required in the course of doing business. In major metropolitan areas where free truck parking is scarce, this can be a significant annual expense — don't overlook it.
Docs needed: Receipts from truck stops, parking lot tickets. Many truck stop chains (Loves, Pilot/Flying J, TA) can provide account history if you use their rewards programs.
Typical annual amount: $500–$3,000
08 Electronics & Communications
📡
ELD (Electronic Logging Device)
Hardware, subscription, and support fees
100% Deductible
Your ELD is a federally mandated business expense — the hardware purchase and any monthly service fee are 100% deductible. The hardware can be expensed outright under the IRS small business safe harbor (items under $2,500) or Section 179. Monthly subscription costs are deducted as an operating expense in the month paid.
Docs needed: Purchase receipt for hardware, monthly subscription invoices or statements.
Truck-specific GPS units (Garmin dēzl, Rand McNally, Sygic Truck) and navigation app subscriptions are fully deductible as business tools. These are business-only equipment — there's no dual-use issue. Hardware under $2,500 can be expensed immediately; subscriptions are a monthly operating expense.
Your smartphone and phone plan are deductible to the extent they're used for business. If you use your phone 80% for business (dispatch calls, load board apps, navigation, carrier communication) and 20% personal, 80% of your annual phone cost is deductible. Keep a reasonable log or estimate — the IRS doesn't require a minute-by-minute tally but does expect a rational basis for your business use percentage. A dedicated business phone is 100% deductible.
Docs needed: Phone bills, estimate of business use percentage (document your basis for the estimate).
Typical annual phone cost × business use %: $600–$1,500
💻
Load board & trucking app subscriptions
DAT, Truckstop.com, NetMile, dispatch software
100% Deductible
Subscriptions to load boards (DAT, Truckstop.com, 123Loadboard) and trucking management apps used to run your business are fully deductible. This includes dispatcher software, accounting tools, mileage tracking apps, and any SaaS product you use exclusively for business operations. These are small individual amounts that add up — make sure they're captured in your records.
CB radio, inverter/converter, power strips, auxiliary lighting for safety, and other truck equipment used for business operation are deductible. Items under $2,500 can be expensed immediately. Items primarily for driver comfort (microwave, refrigerator) are deductible as business expenses since they're necessary for extended away-from-home operation — document them as "cab supplies and equipment" rather than personal expenses.
Docs needed: Receipts for each item purchased.
Typical annual amount: $300–$1,500
09 Licenses, Permits & Professional Fees
📄
Trucking licenses & permits
CDL renewal, DOT physical, IFTA, UCR, IRP, OS/OW
100% Deductible
All licensing and permit fees required to operate legally are fully deductible: CDL renewal fees, DOT physicals, IFTA license and decal fees, Unified Carrier Registration (UCR), International Registration Plan (IRP/apportioned plates), oversize/overweight permits, state fuel permits, and any other required compliance permits. These are ordinary and necessary business expenses — every dollar is deductible in the year paid.
Docs needed: Receipts or payment confirmations from DMV, FMCSA, and state agencies. Keep the license/permit itself as supporting documentation.
Typical annual total: $1,000–$3,500
🧾
Accounting & tax preparation
CPA fees, bookkeeping services, tax software
100% Deductible
Fees paid to a CPA, tax preparer, or bookkeeper for preparing your business tax returns and managing your business finances are fully deductible. Tax software costs (TurboTax Self-Employed, QuickBooks) used for your business are also deductible. Note: only the business portion of tax preparation is deductible on Schedule C — if your CPA charges a blended rate covering both business and personal return, ask for an itemized invoice showing the Schedule C portion.
Docs needed: Invoices from CPA or bookkeeper specifying services, software subscription receipts.
Typical annual CPA cost for trucking returns: $500–$1,500
📢
Dispatch fees & factoring fees
Third-party dispatch, freight broker fees, factoring company charges
100% Deductible
If you use a dispatch service, the fees are fully deductible as a business expense. Freight factoring fees — the percentage a factoring company takes to advance your invoices — are also fully deductible. These are essentially a cost of doing business, similar to interest. If your gross revenue on settlements already has factoring fees deducted, verify whether to report gross + deduct fees vs. net — ask your CPA. Generally, report gross income and deduct fees separately.
Education and training costs that maintain or improve skills required for your current trucking business are deductible: hazmat endorsement training and testing fees, defensive driving courses, OSHA certifications, DOT-required training programs, and industry certifications. Note: education that qualifies you for a new career is not deductible — but courses that maintain your CDL and existing trucking qualifications are clearly deductible.
Docs needed: Course invoices or receipts, certification documents.
Typical annual amount: $200–$800
🔐
Self-employment tax deduction
50% of SE tax reduces your AGI (Schedule 1)
50% Above-the-Line
You can deduct 50% of the self-employment tax you pay as an above-the-line deduction on Schedule 1. This is automatic — your tax software calculates it from your Schedule SE. At $80,000 net profit, SE tax is approximately $11,300. You deduct 50% ($5,650) directly from your gross income before calculating income tax. You don't need to do anything special to claim this — it's generated automatically from Schedule SE.
Docs needed: Generated automatically from your Schedule SE calculation. No additional documentation needed.
At $80K net profit: ~$5,650 deduction

Receipts
The documentation rule: For any deduction you take, you need enough documentation to prove (1) the amount, (2) the business purpose, and (3) the date. A credit card statement alone doesn't prove business purpose. An itemized receipt or invoice does. When in doubt, keep both.
✓ Don't Leave Money on the Table
The list above isn't theoretical — these are deductions that apply to the actual operating costs of running a trucking business. Most owner-operators who work with a CPA and maintain clean records end up with effective tax rates well below what a salaried employee pays on the same gross income, precisely because these deductions offset so much of the gross revenue.
The deductions don't happen automatically. You need records: fuel receipts, maintenance invoices, logbook days for per diem, insurance declarations, and subscription statements. The IRS doesn't disallow legitimate expenses — they disallow expenses you can't substantiate.
NetMile's Tax Tracker is built for this: capture receipts with your camera, categorize by deduction type, and have your records organized before your CPA asks for them. Combined with automatic expense totals for cost-per-mile visibility, it's the financial foundation every owner-operator business needs.
