Under IRS Publication 463, commercial truck drivers can deduct the official $69 daily transportation per-diem rate at an 80% allowance for nights away from home. Additional major write-offs include fuel, scale tickets, shower fees, ELD software, satellite radio, load locks, medical exam fees, and truck depreciation.
- ✓The special IRS transportation per-diem rate is $69/day for nights spent away from your tax home (80% deductible).
- ✓Ordinary expenses like CAT scale tickets, showers, load locks, and work boots are 100% tax deductible.
- ✓Equipment depreciation (Section 179 and Bonus Depreciation) can offset tens of thousands in net income in Year 1.
- ✓Keep digital copies of receipts: thermal paper stubs fade within 6 months and will be rejected in an IRS audit.
1. The IRS Pub 463 Transportation Per-Diem Rule
The single largest recurring write-off for over-the-road truckers is the federal transportation meal per-diem allowance under IRS Publication 463. Unlike standard corporate travelers who are limited to a 50% meal deduction, individuals subject to Department of Transportation Hours of Service rules are granted a special 80% deduction rate.
The official standard continental U.S. rate is $69 per full day away from your tax home. This means for every full 24-hour period on the road, you receive a $55.20 tax deduction ($69 × 80%) without needing to save individual restaurant receipts or grocery stubs. You simply need to verify your days away through your ELD electronic logbook.

3. Tractor & Equipment Depreciation (Section 179)
When you purchase a tractor or trailer, you do not write off the purchase price in one lump sum under standard operational expenses. Instead, you recover the cost through capital depreciation.
Under IRC Section 179 and Bonus Depreciation rules, eligible motor carriers can deduct up to 100% of the cost of qualifying commercial vehicles put into service during the tax year. For example, purchasing a $140,000 used tractor can provide an immediate first-year tax deduction that offsets substantial taxable net freight revenue.
4. Non-Deductible Traps to Avoid
Be aware of expenses that auditors routinely disallow: Speeding tickets and DOT roadside violation fines are legally non-deductible under federal law. Personal clothing (jeans, everyday shirts) cannot be written off unless it is specialized protective gear with company branding. Commuting miles from your home to your terminal are also personal.
5. How to Keep Audit-Proof Digital Records
Thermal receipts printed at fuel islands fade into unreadable blank slips within 3 to 6 months due to heat inside a truck cab. In an audit, blank receipts equal zero deductions.
Use a cloud-based client portal or mobile scanner to snap photos of receipts immediately after paying. Stratefile links receipts directly to your general ledger transactions for bulletproof IRS defense.
