Under IRC §280F, passenger vehicles under 6,000 lbs GVWR face annual depreciation caps. For 2024, the Year 1 limit is approximately $12,400 (or $20,400 with bonus depreciation). The deduction is spread over 5+ years.
Getting the deduction right is not just about whether it is allowed — it is about how you set it up.
Document all business trips. The deduction is prorated by business-use percentage.
Mileage log is essential. Save purchase invoice.
Consider using the standard mileage rate (67 cents/mile in 2024) instead of actual expenses -- it may yield a larger deduction for lower-cost vehicles.
Do not confuse the standard mileage rate with actual expense method -- you must choose one and stick with it.
For high-mileage business drivers, the standard mileage rate often beats actual expenses on smaller cars.
When structured correctly, this deduction can significantly reduce your taxable income.
Here is how this deduction typically works in real situations:
A consultant drives 20,000 business miles/year in a Toyota Camry.
An S-Corp reimburses the owner for business miles under an accountable plan.
Owner claims 100% business use on a car also used for personal errands.
Key Takeaway: The difference between a valid deduction and a denied one usually comes down to documentation, usage percentage, and proper structuring. The same expense can be fully deductible, partially deductible, or not deductible at all — depending on how it is handled.
For vehicles under 6,000 lbs, the Year 1 deduction is capped at approximately $12,400 under IRC §280F luxury auto limits.
For lower-cost vehicles with high business mileage, standard mileage (67 cents/mile in 2024) often yields a larger deduction.
