Is tax write off for vehicle over 6000 lbs a valid tax write-off?
TL;DR
Yes, a vehicle over 6,000 lbs can be a valid tax write-off under certain conditions, primarily through Section 179 deduction and bonus depreciation, but it must be used predominantly for business purposes.
Detailed Answer
Where to Put It on the Tax Form
Schedule C, Line 13 for depreciation; Form 4562 for Section 179 and bonus depreciation.
Real World Example
A real estate agent purchases a new SUV for $60,000, which is used 80% for business purposes. They can deduct $28,900 under Section 179 and apply bonus depreciation to the remaining business-use portion of the cost. The deduction is reported on Schedule C and Form 4562.
Calculation Required
A calculation is required for this deduction.
To calculate the deduction, determine the business-use percentage of the vehicle. Apply the Section 179 limit to the business-use portion of the cost, then apply bonus depreciation to any remaining business-use cost. For example, if a vehicle costs $60,000 and is used 80% for business, the business-use portion is $48,000. Deduct $28,900 under Section 179, then apply bonus depreciation to the remaining $19,100.
Audit Risk & Documentation Tips
Moderate audit risk. Maintain detailed mileage logs, purchase receipts, and records of business versus personal use. Ensure that the vehicle is used more than 50% for business to qualify for Section 179 and bonus depreciation. Keep records for at least three years after filing the tax return.
