Is Car Depreciation Tax Deductible?

Quick Answer: ✅ Yes — You can deduct depreciation on a business vehicle, and Section 179 or bonus depreciation may let you write off a large portion in year one.

The Short Answer

When you buy a car for business use, you can't deduct the full purchase price as an expense in one year (in most cases). Instead, you depreciate it — deducting a portion of the cost each year over the vehicle's useful life. However, Section 179 expensing and bonus depreciation can significantly accelerate the write-off, especially for vehicles over 6,000 lbs GVWR.

IRS Rules for Deducting Car Depreciation

IRS Publication 946 (How to Depreciate Property) and Publication 463 cover vehicle depreciation. Vehicles are classified as 5-year MACRS property, but "luxury vehicle" limits (which apply to most passenger cars) cap annual depreciation amounts.

Key rules:

• You must use the actual expense method — depreciation is not available with the standard mileage rate (exception: if you used standard mileage in the first year, you can switch to actual expenses later but must use straight-line depreciation)
• The vehicle must be used more than 50% for business to claim accelerated depreciation
• Luxury vehicle limits (2024): Year 1: $12,400 (with bonus depreciation: $20,400)

  Year 2: $19,800

  Year 3: $11,900

  Year 4+: $7,160
• Vehicles over 6,000 lbs GVWR (SUVs, trucks) are exempt from luxury limits — Section 179 deduction up to $28,900 (2024) plus bonus depreciation on the remainder
• Section 179 lets you expense the business-use portion upfront (subject to limits)
• Bonus depreciation (60% for 2024, phasing down 20% per year) applies to new and used vehicles

How Much Can You Deduct?

Passenger car (under 6,000 lbs GVWR) — $50,000 purchase, 100% business use:

Heavy SUV/Truck (over 6,000 lbs GVWR) — $65,000 purchase, 100% business use:

The heavy vehicle exception is why you see so many business owners buying Ford F-150s, Toyota Land Cruisers, and Chevy Suburbans.

How to Categorize in QuickBooks

• QBO Category: Depreciation (fixed asset depreciation schedule)
• Schedule C Line: Line 13 (Depreciation and Section 179 expense deduction) — also reported on Form 4562
• Tip: Set up the vehicle as a fixed asset in QBO when purchased, then record depreciation as a journal entry each year. Your tax preparer will calculate the exact amount using Form 4562.

Common Mistakes to Avoid

1. Not checking the GVWR before buying. The 6,000-lb threshold is based on Gross Vehicle Weight Rating (from the manufacturer), not curb weight. Check the door sticker or manufacturer specs.
2. Claiming depreciation while using the standard mileage rate. These are mutually exclusive in the same year. If you used standard mileage in year one, you're limited to straight-line depreciation if you switch later.
3. Forgetting the business-use percentage drops the deduction. If business use falls below 50%, you lose accelerated depreciation and must recapture previously claimed amounts.

Record-Keeping Requirements

• Keep the purchase agreement showing the vehicle cost, date acquired, and GVWR
• Maintain a mileage log documenting business vs. personal use percentage each year
• File Form 4562 (Depreciation and Amortization) with your tax return
• Track the vehicle's adjusted basis (original cost minus accumulated depreciation) for when you sell or trade in
• Retain records for at least 3 years after you dispose of the vehicle
