Providing a company vehicle to employees is one of the most common fringe benefits, but the tax rules are detailed. The IRS requires that personal use of a company vehicle be valued and included in the employee’s gross income as a taxable fringe benefit under IRC 61 and Treas. Reg. 1.61-21. The employer must choose one of three IRS-approved valuation methods at the start of the arrangement, track personal vs. business use, include the personal use value on the employee’s W-2, and pay FICA on the amount. The business can deduct the full cost of the vehicle (purchase or lease) as a business expense, but passenger automobiles are subject to annual depreciation caps under IRC 280F. Trucks and SUVs over 6,000 pounds gross vehicle weight rating (GVWR) are exempt from the 280F caps, which is why these vehicles are popular for business use, though they face a separate $31,300 Section 179 cap (2025).

✓Key takeaway

Personal use valuation methods:

Method	How It Works	Requirements	Best For
General valuation rule	FMV of the personal use benefit (what it would cost to lease a similar vehicle for personal use)	Must determine FMV annually	High-value vehicles with minimal personal use
Cents-per-mile rule (2025: 70 cents/mile)	Personal miles x IRS standard mileage rate	Vehicle FMV must not exceed $62,000; vehicle must be used regularly in business; must be chosen by the first day the vehicle is available	Low personal mileage, vehicles under the value cap
Annual lease value (ALV) table	IRS table based on vehicle FMV, prorated for personal use percentage	Must commit at the start; FMV determined when first available to employee	Most company cars (simplest for regular use)

IRC 280F depreciation caps (2025, passenger automobiles):

Year	Without Bonus	With 100% Bonus
Year 1	$12,400	$20,400
Year 2	$19,800	$19,800
Year 3	$11,900	$11,900
Year 4+	$7,160/year	$7,160/year

Heavy vehicles (6,000+ lbs GVWR):

Item	Limit
Section 179 cap (SUVs)	$31,300 (2025)
Bonus depreciation	No 280F cap; full bonus on remaining cost
Total Year 1 deduction	$31,300 (179) + remaining cost via bonus = full cost
Examples	Ford F-150, Chevy Silverado, Toyota Land Cruiser, BMW X5, Mercedes GLE, Cadillac Escalade

How do you structure a company car to minimize taxes?

Hypothetical example

Round numbers. An S-Corp provides a $55,000 sedan (under 6,000 lbs GVWR) to its owner-employee. The vehicle is used 75% for business and 25% for personal use. Total miles driven: 20,000 (15,000 business, 5,000 personal).

Step 1: Employer deducts the vehicle cost (subject to 280F)

Year	Depreciation Deduction (with bonus)	75% Business Use
Year 1	$20,400 (280F cap with bonus)	$15,300
Year 2	$19,800	$14,850
Year 3	$11,900	$8,925
Year 4	$7,160	$5,370
Year 5	$7,160	$5,370
Years 6-8	$7,160/year	$5,370/year
Total depreciation	~$55,000 (over ~8 years)	~$41,250

Without the 280F caps, the S-Corp would deduct $55,000 x 75% = $41,250 in Year 1 using bonus depreciation. Instead, it takes ~8 years to deduct the same amount.

Step 2: Value the personal use (included on W-2)

Method 1: Cents-per-mile (eligible because FMV under $62,000):

Item	Amount
Personal miles	5,000
Rate (2025)	$0.70
Personal use value	$3,500

Method 2: Annual lease value table:

Vehicle FMV	Annual Lease Value (from IRS table)
$55,000	~$15,250
Personal use percentage	25%
Personal use value	$3,813

The cents-per-mile method produces a lower personal use value ($3,500 vs. $3,813), so the employee would prefer it.

Step 3: Tax impact on the employee

Item	Amount
Personal use value added to W-2	$3,500
Employee’s marginal tax rate (24%)	$840 income tax
Employee FICA (7.65%)	$268
Total additional tax to employee	$1,108

The employee receives the benefit of driving a $55,000 car for personal use (valued at $3,500/year) in exchange for $1,108 in additional tax. The equivalent cost of owning a personal vehicle for 5,000 miles (depreciation, insurance, maintenance, fuel) would be far higher.

Step 4: S-Corp employer tax benefits

Item	Amount
Vehicle purchase price	$55,000
Year 1 depreciation (280F with bonus)	$20,400
Operating expenses (gas, insurance, maintenance)	$6,000
Total Year 1 deduction	$26,400
Business use portion (75%)	$19,800
Tax savings (24%)	$4,752

Heavy SUV comparison (over 6,000 lbs GVWR): Same scenario, but with a $75,000 SUV (7,000 lbs GVWR):

Item	Sedan ($55,000)	Heavy SUV ($75,000)
Section 179	Limited by 280F	$31,300
Bonus depreciation (Year 1)	$20,400 (280F cap)	$43,700 (remaining cost: $75,000 - $31,300)
Total Year 1 deduction	$20,400	$75,000
Business use deduction (75%)	$15,300	$56,250
Tax savings (24%)	$3,672	$13,500

The heavy SUV provides $9,828 MORE in Year 1 tax savings because it’s exempt from the IRC 280F depreciation caps.

Fleet program structure (multiple vehicles):

Element	Recommendation
Written vehicle policy	Required: states who is eligible, business use requirements, personal use reporting
Mileage tracking	GPS app or manual log (contemporaneous records)
Personal use reporting	W-2 inclusion, method chosen at year start
Insurance	Business auto policy (covers both business and personal use)
Fuel cards	Company fuel card with business-only restriction or tracking
Commuting rule option	If vehicle is used primarily for commuting: $1.50/one-way commute or $3/day (not available for control employees)

The commuting valuation rule (Treas. Reg. 1.61-21(f)):

Requirement	Details
Employee must commute in the vehicle	Can’t be garaged at business location
No personal use other than commuting	De minimis personal use allowed (stop for errands)
Written policy prohibiting personal use	Required
Valuation	$1.50 per one-way commute ($3/day)
NOT available for	Control employees (officers, directors, 1%+ owners)

For rank-and-file employees, the commuting rule produces the lowest W-2 inclusion: $3/day x 250 workdays = $750/year, compared to $3,500+ under other methods. S-Corp owner-employees cannot use this rule.
