Self-employed / business use
Qualifying business driving can generally be deducted using the standard mileage method or actual expenses when the method's IRS requirements are met.
2026 business mileage deduction
Business mileage deduction in 2026: standard mileage or actual expenses?
Self-employed drivers can generally deduct qualifying business vehicle costs. The practical choice is usually between the IRS standard mileage method and actual car expenses — and both still depend on separating business driving from personal use.
Quick answer
Can you deduct mileage on your taxes?
For a self-employed taxpayer, qualifying car expenses are generally business expenses reported with the business. Most W-2 employees cannot take a federal deduction for unreimbursed business mileage in 2026, although limited exceptions remain.
Most W-2 employee mileage
Unreimbursed employee travel expenses are generally not deductible on the federal return. Specific employee categories and eligible educators can have exceptions.
Ordinary commuting
Driving between home and a regular workplace is generally personal commuting, not business mileage. Business transportation can be treated differently depending on the facts.
Standard mileage vs. actual expenses
If you qualify to use either method, the IRS itself notes that comparing both can help show which produces the larger deduction. The methods calculate the vehicle expense differently, but the same underlying question remains: what share of the vehicle's use was genuinely for business?
Method 1
Standard mileage
76¢per qualifying business mile from July 1, 2026- 72.5¢/mile Jan. 1–Jun. 30
- 76¢/mile Jul. 1–Dec. 31
- Track qualifying business miles
- Business parking and tolls can generally be separate
You generally cannot also deduct depreciation, lease payments, insurance, repairs, registration or other actual operating expenses for the same year.
Method 2
Actual car expenses
Eligible vehicle costs×business-use %
- Track eligible operating costs and ownership/lease costs
- Separate business and personal use
- Apply depreciation or lease rules where relevant
- Keep receipts and supporting records
Passenger-vehicle depreciation, lease inclusion amounts and other limits can affect the final deduction.

The 2026 standard mileage rate changed on July 1
There are two business rates in 2026. The IRS increased the rate midyear, so trip dates matter when calculating the standard mileage deduction.

Example: calculating a 2026 standard mileage deduction
Suppose a self-employed driver has 2,000 qualifying business miles in the first half of 2026 and 3,000 qualifying business miles after July 1.
2,000 miles × $0.725$1,450
3,000 miles × $0.76$2,280
Illustrative standard-mileage amount$3,730
This illustrates the mileage calculation only. Whether the miles qualify and how the deduction is reported depends on the taxpayer's circumstances.
Actual expenses still require mileage
Choosing actual expenses does not remove the need for a driving record. When the same Tesla is used for both business and personal purposes, the IRS requires the expenses to be divided between those uses. Mileage is a common basis for calculating that business-use percentage.
Vehicle-cost records
- Insurance and registration
- Repairs, tires and maintenance
- Eligible operating costs
- Depreciation or lease payments, subject to rules
Use records
- Total miles driven
- Business miles
- Date and destination
- Business purpose
Your first-year choice can matter later
Owned vehicleWant to preserve the standard-mileage option?
Generally choose the standard mileage method in the first year the car is available for business use.
→
Later yearsYou may be able to switch
An owned vehicle can generally move from standard mileage to actual expenses later, but depreciation rules then change.
→
Leased vehicleStandard mileage locks in
If you choose standard mileage for a lease, you generally must use it for the entire lease period, including renewals.
Commuting is not the same as business mileage
Ordinary driving from home to your regular workplace is generally personal commuting. Trips between business locations, client visits and other qualifying business transportation can be different. A home that qualifies as your principal place of business can also change the treatment of some trips from home.
That is why DriveQuery should not silently decide that a trip is tax-deductible. The useful automation is to capture the drive, remember places and patterns, and make the unresolved trips easy for the driver to classify.
What should a business mileage record contain?
For car expenses, IRS recordkeeping focuses on contemporaneous evidence of the business use. A practical trip record should preserve the mileage together with the context needed to explain why the drive was business-related.
Trip facts
- Date
- Business destination
- Mileage for each business use
- Total vehicle mileage for allocation
Business context
- Business purpose
- Client, site or project when useful
- Business/personal classification
- Review history before export
Why this fits a Tesla mileage tracker
A Tesla already produces the trip facts that are hardest to reconstruct months later. DriveQuery is designed to turn that vehicle history into a reviewable business-mileage workflow: capture drives automatically, recognize user-defined places, suggest familiar classifications and keep uncertain trips visible until the driver confirms them.
DriveQuery organizes evidence; it does not make the tax election. The taxpayer or adviser should decide whether standard mileage or actual expenses are available and appropriate, and which trips qualify.

FAQ
Business mileage deduction: common 2026 questions
Can self-employed taxpayers deduct business mileage in 2026?
Generally, qualifying self-employed car expenses can be deducted as business expenses. Eligible taxpayers may use the standard mileage rate or actual car expenses when the IRS rules for that method are met.
What is the 2026 business mileage deduction rate?
The IRS business standard mileage rate is 72.5¢ per mile from Jan. 1 through June 30, 2026, and 76¢ per mile from July 1 through Dec. 31, 2026.
Can I deduct commuting miles?
Ordinary travel between your home and your regular workplace is generally nondeductible commuting. Different rules can apply to qualifying business transportation, temporary work locations and a home that qualifies as your principal place of business.
What is the difference between standard mileage and actual expenses?
The standard mileage method applies an IRS cents-per-mile rate to qualifying business miles. The actual-expense method tracks eligible vehicle costs and allocates the business-use share. You cannot deduct both methods for the same vehicle use in the same year.
Do I still need mileage records if I use actual expenses?
Yes. When a vehicle has both business and personal use, records are needed to support the business-use percentage. Mileage is commonly used to divide those uses.
Can most W-2 employees deduct unreimbursed business mileage in 2026?
Generally no. Federal law permanently disallows the miscellaneous itemized deduction for unreimbursed employee travel expenses, although limited categories of employees and eligible educators can have different rules.
The tax method can change. The trip history should not.
