For owner-operators who own trucks outright, the IRS offers two valuable tools to reduce their taxable income: Section 179 and bonus depreciation. While not obscure concepts, these rules are crucial for those purchasing equipment and need to understand how they work.
The standard approach is to spread the deduction across a truck's useful life, which can be five years under the MACRS schedule. However, this method may not always yield the most beneficial results.
Section 179 allows businesses to deduct the full purchase price of qualifying equipment in the year it is placed in service, rather than spreading the cost over several years.
For 2026, the maximum Section 179 deduction is $2,560,000, according to IRS Revenue Procedure 2025-32. This means that owner-operators can potentially deduct up to 100% of their truck's purchase price in year one.
However, it's essential to note that Section 179 cannot create a loss. The deduction is capped at the business's net taxable income from the operation. If an owner-operator earns $120,000 in taxable income and buys a $160,000 truck, they can deduct up to $120,000 under Section 179.
The remaining $40,000 of purchase cost carries forward as a Section 179 carryover deduction that can be applied in future tax years.
Bonus depreciation is another tool that allows businesses to depreciate equipment more aggressively. It had been phased out under the 2017 Tax Cuts and Jobs Act but was restored to 100% for qualifying equipment under the One Big Beautiful Bill Act.
This means that owner-operators can potentially eliminate their entire federal income tax liability in year one by deducting the full purchase price of their truck under Section 179. The cash they would have sent to the IRS stays in their business.
By understanding and utilizing these tax breaks, owner-operators can reduce their taxable income and save real money on their taxes.
The tax math behind these breaks is complex, but understanding them can save business owners real money.
