The IRS Mileage Rate Is Not Your Break-Even Number

Treating the deduction rate as a break-even number can make an unprofitable trip look acceptable. A platform offer can pay more than 76 cents per dispatched mile and still lose money once you include the drive back, idle time, repairs, insurance, depreciation, and the value of your time.

AAA's 2025 study estimates that, at 15,000 miles per year, selected gas-powered medium sedans averaged about 66.4 cents per mile, while selected gas-powered medium SUVs averaged about 83.9 cents per mile. [4] Those figures describe selected new vehicles under AAA's methodology—not your exact car—but they show why one national tax rate cannot be a universal cost model.

The midyear change creates a separate recordkeeping issue. Miles tied to qualifying expenses before July 1 remain under the earlier rate, while qualifying expenses on or after July 1 use the revised rate. Mixing the periods can distort the deduction before you even reach the profitability question.

The IRS announced the initial 72.5-cent 2026 business rate on December 29, 2025, effective January 1. It said the business rate is based on an annual study of the fixed and variable costs of operating an automobile and that using the standard rate is optional. [1]

In Internal Revenue Bulletin 2026-29, published July 13, the IRS revised the business rate to 76 cents per mile for qualifying expenses paid or incurred on or after July 1, 2026. The announcement says the modification resulted from recent fuel-price increases and confirms that Notice 2026-10 continues to apply before July 1. [2]

IRS Topic 510 describes two general approaches: the standard-mileage method and the actual-expense method. Actual expenses can include the business portion of gas, oil, repairs, tires, insurance, registration fees, licenses, and depreciation or lease payments. It also explains eligibility limits, recordkeeping, and where self-employed taxpayers report qualifying vehicle expenses. [3]

Use the IRS rate for the job it was designed to do: tax substantiation. Use your own records for operating decisions.

Start with one month of vehicle costs. Add fuel, maintenance, insurance, registration, financing or lease costs, and a reasonable allowance for depreciation. Separate business use from personal use, then divide the business portion by business miles. Track unpaid return miles as business activity when appropriate under your facts, but do not assume every mile qualifies for a deduction.

For each platform offer, compare expected pay with all miles, expected time, and your own cost per mile. Then evaluate the standard-mileage and actual-expense methods separately. IRS rules can restrict method choices based on vehicle history and prior depreciation decisions, so confirm the filing treatment with a qualified tax professional. [3]

The larger signal is that a government mileage rate is a policy tool, not a real-time earnings standard. It is designed to simplify substantiation across millions of taxpayers, not to price a specific driver's vehicle, labor, or local market.

As fuel, insurance, repair, and vehicle prices move at different speeds, the gap between a national rate and an individual driver's economics can widen or narrow. The durable advantage is maintaining your own cost record and updating it regularly.
