Buying or Leasing a Truck? What It Means for Your 2026 Taxes

A truck or trailer is a major investment for an owner-operator. How you acquire that equipment affects how you deduct its cost. Before signing an agreement, understand whether you are buying equipment or renting it—and remember that a tax deduction reduces taxable income, rather than reducing your tax dollar for dollar.

Purchased tractors and trailers have different tax timelines. Over-the-road tractors generally fall into a 3-year depreciation class, while trailers generally fall into a 5-year class under the standard federal depreciation system. Depreciation lets you deduct equipment costs over time. These time periods are determined by tax law.

You may qualify for a faster deduction in 2026. Eligible new or used equipment acquired and placed in service after January 19, 2025, may qualify for 100% bonus depreciation. Section 179 offers another way to deduct qualifying purchases sooner, subject to income and other limits. Equipment must be ready and available for business use; placing an order or making a deposit alone does not qualify. Taking a larger deduction now also leaves less depreciation for future years.

A true truck lease is generally a rent expense. When your agreement is a true lease, you generally deduct the business portion of the lease payments instead of depreciating the truck yourself. You are paying to use someone else’s equipment. For example, qualifying weekly truck rental charges shown on your carrier settlements generally fall into this category.

A “lease-purchase” label does not settle the question. An agreement may actually be a purchase if payments build ownership, title transfers after required payments, or you can buy the truck for a very small amount compared with its expected value. A $1 buyout is a strong reason to have the contract reviewed. No single feature decides every case; the full agreement matters.

Financing a purchase does not turn it into rent. If you buy equipment with a loan, you generally recover its cost through depreciation, even while making payments. The principal portion of each payment is not a separate expense deduction; qualifying business interest is generally deductible separately. Likewise, a lease-purchase agreement treated as a purchase should not also be deducted as weekly rent.
