What Is Section 179?
Section 179 is a tax code that allows business owners to expense the purchase price of a commercial vehicle under certain conditions. It encourages company growth while incentivizing business owners to invest in heavy-duty equipment.
Understanding Section 179 for 2025
Since new legislation was passed in the summer of 2025, businesses can now deduct up to $2.5 million before reaching the $4 million threshold. If your expenses surpass the upper limit, your deduction cap begins to drop $1 for each dollar over.1 We know the intricacies can be a bit complex, but you can contact your tax professional or our dealership to dive deeper into the Section 179 rules. In addition, to satisfy the conditions, your vehicle needs to meet Section 179 weight requirements and spend the majority of its time being used for business purposes.
Weight Stipulations for Section 179 (Over 6,000 Pounds)
Vehicles that meet the Section 179 GVWR rating between 6,000 and 14,000 pounds – new or used – and are used at least 50% for business purposes typically qualify for a tax deduction and bonus depreciation. This includes SUVs, trucks, and vans that reach the Section 179 vehicle weight threshold, though certain commercial vehicles may exceed the 14,000-pound maximum.
Included are specialized work vehicles such as ambulances, box trucks, vehicles seating nine or more passengers, and pickups or vans with cargo areas of 6 feet or longer. Keep in mind that deductions are capped at your taxable income.
How Do You Claim the Section 179 Deduction?
You can claim the deduction while filing your company's taxes by filling out IRS Form 4562. Here is some of the key information you'll need to have on hand:
- Purchase date and first date of service (the latter is key, because it must fall within the tax year)
- Business expenses, including any maintenance and repair costs
- The level of use for your business
- Your reasons for expensing the commercial vehicle
