If you use your personal vehicle for business, those trips may cost more than you realize.
Whether you’re meeting clients, delivering products, visiting job sites, or picking up supplies, qualifying business driving can create deductible expenses.
But claiming a business mileage deduction isn’t as simple as counting every mile you drive.
The IRS has rules about eligible trips, commuting, deduction methods, and recordkeeping. Understanding those rules can help you claim legitimate expenses without overstating your deduction.
Here’s what small business owners need to know.

What Is a Business Mileage Deduction?
A business mileage deduction allows eligible taxpayers to deduct qualifying vehicle costs associated with operating a business.
Self-employed individuals, independent contractors, and businesses may qualify, depending on their circumstances and how vehicle expenses are paid or reimbursed.
Generally, eligible taxpayers can calculate deductible vehicle costs using one of two methods:
- Standard mileage method: Multiply qualifying business miles by the applicable IRS rate.
- Actual expense method: Deduct the allowable business portion of vehicle operating costs.
Employees generally cannot deduct unreimbursed work-related mileage on their federal returns, although limited exceptions apply.
A mileage deduction reduces taxable income; it doesn’t reduce your tax bill dollar for dollar.
What Counts as Business Mileage?
Not every work-related drive qualifies.
Depending on your circumstances, deductible business trips may include:
- Traveling between business locations
- Driving to client meetings or job sites
- Picking up business supplies
- Making business deliveries
- Attending qualifying business conferences or meetings
- Running business-related errands
For example, a self-employed photographer driving from their studio to a client’s location may have deductible business mileage.
However, ordinary commuting is treated differently.
Business Mileage vs. Commuting
Your regular drive between home and your main workplace is generally considered commuting, even if you discuss business on the phone or carry work materials.
Commuting expenses are normally nondeductible.
Special rules may apply when traveling between workplaces, visiting qualifying temporary work locations, or operating from a home office that qualifies as your principal place of business.
Important: Driving from home to a temporary work location isn’t automatically deductible. Eligibility depends on factors such as your regular work location, metropolitan area, and expected assignment duration.
When uncertain, review the trip with a qualified tax professional.
How Does the IRS Standard Mileage Rate Work?
The IRS publishes optional standard mileage rates used to calculate qualifying vehicle deductions.
Rates can change between tax years and, occasionally, during a year.
Under this method, you multiply qualifying business miles by the rate applicable to the date of travel.
IRS Business Mileage Rates: 2026 Reference
| January 1–June 30, 2026 | 72.5 cents per mile |
| July 1–December 31, 2026 | 76 cents per mile |
These figures apply specifically to the periods shown. For another tax year, use the IRS rate applicable to that year’s travel dates.
Example: Calculating Your Mileage Deduction
Suppose you drove 4,000 qualifying business miles during a period when the applicable rate was $0.70 per mile.
Your calculation would be:
4,000 miles × $0.70 = $2,800
This is an illustrative calculation, not a statement of the current IRS rate.
Assuming you’re eligible for the standard mileage method, the result is a potential deduction from taxable income—not a $2,800 tax refund.
Standard Mileage Method: What Does It Cover?
The standard mileage method simplifies calculations because you don’t have to allocate every fuel or repair bill separately.
The rate generally accounts for vehicle operating costs, including:
- Fuel and oil
- Maintenance and repairs
- Insurance
- Depreciation
- Other covered operating costs
Qualifying business parking fees and tolls may be deducted separately. Certain vehicle-related interest and taxes may also qualify under applicable rules.
You cannot use the standard mileage rate and separately deduct the same vehicle’s covered operating expenses for the same period.
Can You Switch Deduction Methods?
For an owned vehicle, you generally must choose standard mileage in the first year the vehicle is available for business use to preserve the option of using that method in later years.
Eligible owners may switch to actual expenses in a later year, subject to depreciation restrictions.
Certain depreciation elections or deductions can prevent future use of standard mileage.
For leased vehicles, choosing standard mileage generally requires using that method throughout the lease period, including renewals.
Additional restrictions may apply, including certain fleet operations.
Actual Expense Method: What Can You Deduct?
The actual expense method uses the qualifying business portion of vehicle costs.
Potential expenses include:
- Gas and oil
- Repairs and maintenance
- Tires
- Insurance
- Registration and license fees
- Eligible depreciation or lease expenses
- Certain vehicle-related expenses
- Business parking fees and tolls
Expenses must be appropriately allocated, and some deductions are subject to additional limitations.
Example: Calculating Business Use
Suppose you drove 12,000 total miles during the year, including 7,200 qualifying business miles.
Your business-use percentage would be:
7,200 ÷ 12,000 = 60%
If eligible operating expenses totaled $8,000, the business-use portion would generally be:
$8,000 × 60% = $4,800
Additional depreciation, lease, and vehicle-specific rules may affect the final deduction.
Standard Mileage vs. Actual Expenses: Which Is Better?
Neither method is automatically better.
| Simpler calculations | More detailed expense tracking |
| Uses business miles and IRS rates | Uses actual costs and business-use percentage |
| Often convenient for frequent drivers | May benefit vehicles with higher eligible costs |
| Subject to eligibility restrictions | Subject to depreciation and expense limitations |
If you’re eligible for both, comparing the calculations can help determine which produces the more favorable result.
Don’t choose based only on one year’s deduction. Your initial method and depreciation decisions can affect future years.
Why Accurate Mileage Records Matter
A reliable mileage log is essential for supporting business vehicle deductions.
For each qualifying trip, record:
- Date of travel
- Destination or route
- Business purpose
- Miles driven
Also maintain total annual mileage and supporting information needed to distinguish business, personal, and commuting use.
You can use a paper log, spreadsheet, or mileage-tracking application.
GPS tracking may simplify recordkeeping, but you should still review trip classifications for accuracy.

Common Business Mileage Deduction Mistakes
Even legitimate business expenses can become difficult to substantiate when records are incomplete.
Avoid these common mistakes:
1. Counting commuting as business mileage. Ordinary travel between home and your regular workplace generally doesn’t qualify.
2. Using the wrong mileage rate. Apply the IRS rate for the relevant travel period.
3. Estimating mileage without reliable support. Timely records are generally stronger than reconstructed estimates.
4. Claiming personal driving. Only qualifying business use is deductible.
5. Combining incompatible deduction methods. You generally cannot claim standard mileage and actual operating expenses for the same vehicle during the same period.
6. Ignoring depreciation restrictions. Certain deductions can affect future eligibility for standard mileage.
7. Forgetting supporting records. Maintain appropriate documentation, especially when using actual expenses.
Reviewing your mileage records regularly makes tax preparation easier.
Frequently Asked Questions
Can I deduct mileage if I use my personal car for business?
Yes, if the travel qualifies and you meet the applicable deduction requirements. Personal ownership alone doesn’t prevent a business mileage deduction.
Can I deduct my regular commute?
Generally, no. Ordinary commuting between home and your regular workplace is nondeductible, although specific exceptions may apply.
Can both spouses deduct mileage using the same vehicle?
Potentially, but each spouse must substantiate qualifying business use, and the same expense cannot be deducted twice. Business structure and reimbursement arrangements also matter.
Can rideshare and delivery drivers deduct mileage?
Self-employed drivers may deduct qualifying business vehicle expenses using an eligible method. Personal driving and commuting must be excluded.
What happens if I forget to track mileage?
Missing records can make deductions difficult to substantiate. Preserve available supporting evidence, begin tracking immediately, and consult a tax professional about incomplete periods. Don’t invent trips or mileage amounts.
Final Thoughts: Make Every Business Mile Count
Business mileage deductions can help eligible small business owners account for the real cost of business driving.
The most important habits are straightforward: understand which trips qualify, select an appropriate deduction method, and maintain reliable records throughout the year.
Accurate bookkeeping also helps connect vehicle expenses with your broader financial picture.
