Gig driver mileage deduction guide for 2026

For 2026, the IRS business standard mileage rate changed in the middle of the year. That means drivers using the standard mileage method need to apply the rate that corresponds to when the business miles were driven.

Self-employed drivers who use a vehicle for business may be able to deduct eligible vehicle costs. One method is the IRS standard mileage rate, which uses business miles instead of separately calculating many individual vehicle operating expenses.

The mileage deduction reduces taxable business income. It is not a dollar-for-dollar tax refund.

There are generally two methods for calculating eligible business vehicle expenses.

Standard mileage method: uses eligible business miles multiplied by the applicable IRS business mileage rate.

Actual expense method: uses the business-use share of eligible vehicle costs such as fuel, insurance, repairs, depreciation or lease costs, and other qualifying expenses.

If a taxpayer uses the standard mileage rate for a year, they generally do not also deduct the same vehicle operating expenses — such as gas, insurance, repairs, or depreciation — on top of the mileage rate.

Only business use of a vehicle is relevant to a business mileage deduction. Personal driving is not business mileage, and ordinary commuting between home and a regular place of work is generally treated as personal travel.

Gig work can create fact-specific situations, especially around driving from home to the first pickup, driving after the final delivery, or operating from a qualifying home office. Do not assume that every mile recorded during a delivery day is deductible.

When the treatment of a particular trip is unclear, review IRS Publication 463 or ask a qualified tax professional.

The IRS requires taxpayers to substantiate business vehicle use. A mileage record should be detailed enough to show when the vehicle was used, how much business mileage was driven, where the business travel occurred, and the business purpose.

• Date of the business use
• Mileage for each business use
• Business destination or area
• Business purpose
• Total vehicle mileage for the year

If you use the actual-expense method, additional records and supporting documents may be needed for vehicle expenses.

Electronic mileage records can be acceptable.

IRS Publication 463 states that a record prepared on a computer can qualify as an adequate written record. The important issue is that the record is accurate and adequately supports the business use being claimed.

Mileage records are stronger when they are created close to the time the driving occurs instead of being reconstructed months later. IRS guidance gives more weight to timely records because details are less likely to depend on memory.

A weekly log that accounts for the week's business use can generally qualify as timely under IRS recordkeeping guidance.

The IRS generally says records supporting a deduction should be kept for as long as they may be needed to administer the tax law. Publication 463 notes that this commonly means at least three years from the date the return claiming the deduction is filed, although some situations require longer retention.

For delivery drivers, manually reconstructing a day of pickups, drop-offs, repositioning, and personal driving can be difficult. MileLap is designed to keep route, distance, and trip-classification records together so they can be reviewed later.

MileLap supports automatic and manual mileage tracking, but it does not determine whether a particular trip is tax deductible.
