If you use a car, pickup truck, van, or other qualifying vehicle for business, you may be able to deduct certain vehicle expenses on your federal tax return. The IRS generally provides two primary methods for calculating business vehicle deductions: the standard mileage rate and the actual expense method.
The method available to you—and the amount you can deduct—depends on how you use the vehicle, whether you own or lease it, your business mileage, and the records you maintain.
Key Takeaways
Business vehicle expenses can generally be calculated using the standard mileage rate or actual expenses, when eligible.
Only the portion of vehicle use attributable to business is generally deductible when a vehicle has both business and personal use.
Commuting between your home and regular place of business is generally a personal expense.
Detailed mileage and expense records are essential for supporting a vehicle deduction.
Your choice of method can affect depreciation and the vehicle's tax basis in future years.
The IRS business mileage rate for 2026 is 72.5 cents per mile from January 1 through June 30 and 76 cents per mile from July 1 through December 31.
Who Can Deduct Business Vehicle Expenses?
Vehicle deductions are commonly available to self-employed individuals and business owners who use a vehicle in connection with a trade or business.
Qualifying business trips can include driving to:
Meet clients or customers
Visit business locations
Pick up business supplies
Visit a bank for business purposes
Meet with a business attorney, accountant, or other professional
Perform services at a customer's location
However, not every trip related to work is deductible. Regular commuting between your home and a regular workplace is generally nondeductible personal transportation. Personal errands and other nonbusiness trips generally don't qualify either.
Two Ways to Calculate a Business Vehicle Deduction
If you qualify, you generally have two primary options.
1. Standard Mileage Rate
The standard mileage method uses an IRS-established rate for each qualifying business mile.
For example, if you drive 10,000 qualifying business miles during the first half of 2026, the calculation would be:
10,000 miles × $0.725 = $7,250
Business parking fees and tolls may generally be deducted separately when they are attributable to business use.
The standard mileage method can simplify recordkeeping because you don't generally calculate separate deductions for gasoline, repairs, insurance, depreciation, and similar operating costs.
However, there are eligibility restrictions, and the rules for switching between methods can depend on whether the vehicle is owned or leased.
2. Actual Expense Method
Instead of using the mileage rate, you can calculate your qualifying vehicle expenses and deduct the business portion.
Depending on the circumstances, expenses may include:
Gas and oil
Repairs and maintenance
Tires
Insurance
Registration fees
Lease payments
Garage or parking costs
Depreciation
Business-related tolls and parking
If you use the vehicle for both business and personal purposes, the expenses must generally be allocated between the two uses.
For example:
Total annual mileage: 20,000 miles
Business mileage: 12,000 miles
Business-use percentage: 60%
Under the actual expense method, 60% of eligible vehicle expenses would generally be considered the business portion, subject to applicable IRS rules and limitations.
Can You Deduct the Cost of Buying a Business Vehicle?
Buying a vehicle does not automatically mean you can deduct the entire purchase price in the year you buy it.
If you own the vehicle and use the actual expense method, you may potentially recover the business-use portion of the vehicle's cost through depreciation. Depending on the facts, Section 179 and applicable bonus depreciation rules may also affect the deduction.
These provisions have specific eligibility requirements, limitations, and vehicle-related restrictions.
If you use the standard mileage method, you generally cannot separately deduct the vehicle's purchase price or depreciation. Depreciation is incorporated into the mileage rate, and the vehicle's tax basis must be adjusted accordingly.
Standard Mileage vs. Actual Expenses: Which Is Better?

How Vehicle Use Affects Your Deduction
Business-use percentage is particularly important when a vehicle is shared between business and personal activities.
For example, driving 15,000 total miles with 9,000 business miles results in a 60% business-use percentage.
The remaining personal use generally cannot be deducted as a business expense.
Maintaining an accurate mileage log is therefore one of the most important parts of supporting a vehicle deduction.
What Records Should You Keep?
The IRS requires taxpayers to substantiate business vehicle expenses with adequate records or other sufficient evidence.
Your records should generally support:
Date of each business trip
Business destination
Business purpose
Business miles
Total annual mileage
Vehicle expenses and receipts, when using actual expenses
Date the vehicle was placed in service
Business-use percentage
A mileage-tracking app can make recordkeeping easier, but the information must still accurately reflect the vehicle's actual business use.
Where Is the Deduction Reported?
For a self-employed individual, business vehicle expenses are generally reported on Schedule C (Form 1040). Farmers generally use Schedule F. Depreciation-related deductions may require Form 4562, depending on the circumstances.
The appropriate reporting method can differ for partnerships, corporations, employees, and other taxpayers.
A Practical Approach to Writing Off a Business Vehicle
Before claiming a deduction, consider these steps:
Determine your business use. Separate business miles from commuting and personal mileage.
Choose the appropriate calculation method. Compare the standard mileage and actual expense methods if you qualify for both.
Maintain a mileage log. Record dates, destinations, mileage, and business purposes.
Save receipts. This is especially important when using the actual expense method.
Review depreciation rules. Vehicle depreciation, Section 179, and bonus depreciation can involve additional requirements and limitations.
Use the correct tax forms. The reporting requirements depend on your business structure and circumstances.
Keep your records. Retain documentation supporting both the business use and the deduction.
Final Thoughts
A business vehicle can create a valuable tax deduction, but simply purchasing a car through a business does not automatically make the entire vehicle deductible.
The key is to establish legitimate business use, choose an appropriate deduction method, accurately document mileage and expenses, and apply the IRS limitations that apply to your particular vehicle and tax situation.
