W-2 Employees: Limited Deductibility After TCJA
Vehicle depreciation is deductible for business use -- but the rules differ dramatically based on whether you are a W-2 employee or self-employed. Since the Tax Cuts and Jobs Act of 2017, W-2 employees generally cannot deduct vehicle expenses at all, while self-employed individuals have extensive deduction options. Understanding these rules determines whether vehicle costs reduce your tax bill.
Vehicle depreciation deductibility by taxpayer type
| Taxpayer Type | Vehicle Depreciation Deductible? | Method Available | Record Requirement |
|---|---|---|---|
| W-2 employee (commuting) | No | None | N/A |
| W-2 employee (unreimbursed business travel) | No (TCJA eliminated this) | None through 2025 | N/A |
| W-2 employee (Armed Forces) | Yes (Form 2106) | Standard mileage or actual | Mileage log required |
| Self-employed (Schedule C) | Yes | Section 179, bonus, MACRS, or mileage | Mileage log required |
| S-corp owner/employee | Yes through corporation | Reimbursement or vehicle owned by S-corp | Business use records |
| Partner in partnership | Yes (through K-1) | Varies by partnership agreement | Partnership records |
Prior to 2018, W-2 employees could deduct unreimbursed employee business expenses (including business mileage) as a miscellaneous itemized deduction subject to a 2% AGI floor. The Tax Cuts and Jobs Act of 2017 suspended this deduction through 2025. W-2 employees cannot deduct vehicle expenses on their personal returns -- request employer reimbursement instead.
Self-Employed: Broad Deduction Options
- Self-employed: Section 179 can allow full first-year expensing for qualifying business vehicles
- Standard mileage rate (2025): 70 cents per mile for business -- verify current year IRS rate
- Actual expense method: Deduct actual depreciation, insurance, maintenance, fuel in business-use percentage
- Keep contemporaneous mileage log: Date, destination, business purpose, mileage for every business trip
- Commuting is never deductible -- only travel from your first business stop is deductible
