How do I deduct vehicles that weigh over 6000 lbs on my taxes?

TL;DR

Vehicles weighing over 6,000 lbs can be deductible under Section 179 and bonus depreciation rules, but they must be used predominantly for business purposes. Misconceptions often arise around personal use and the specific weight threshold.

Detailed Answer

To deduct a vehicle over 6,000 lbs, it must be used more than 50% for business purposes. The deduction can be taken under Section 179, allowing immediate expensing of up to $28,900 (as of 2023) for SUVs, or through bonus depreciation, which allows for 80% expensing in the first year. Vehicles must be purchased and placed in service during the tax year. Personal use is not deductible, and strict documentation of business use is required. For example, a real estate agent using a large SUV primarily for client meetings and property tours can deduct the business-use percentage of the vehicle's cost.

Where to Put It on the Tax Form

Schedule C, Line 13 for depreciation and Line 24a for car and truck expenses.

Real World Example

A freelance photographer purchases a new SUV for $50,000, weighing over 6,000 lbs, and uses it 80% for business. They can deduct $28,900 under Section 179 and apply bonus depreciation to the remaining business-use portion of the cost.

Calculation Required

A calculation is required for this deduction.

Calculate the business-use percentage by dividing business miles by total miles driven. Apply this percentage to the vehicle's cost to determine the deductible amount under Section 179 and bonus depreciation.

Audit Risk & Documentation Tips

Moderate audit risk. Keep detailed mileage logs, receipts, and a calendar of business activities to substantiate business use. Ensure the vehicle's weight is documented, such as through the manufacturer's specifications or vehicle registration.
