Worked example
5,000 business miles split 2,000 before July and 3,000 after comes to $3,730 — not $3,800, because the IRS raised the business rate from 72.5 to 76 cents on 1 July 2026. A calculator carrying one rate for the year is wrong for whichever half it left out.
How to work it out yourself
- 1.Split your mileage log at 30 June. The IRS changed the business and medical rates on 1 July 2026, and each half is claimed at its own rate.
- 2.Pick the purpose. The charitable rate is set by statute at 14 cents and has not moved in decades; the business and medical rates are adjusted by the IRS.
- 3.If your employer reimburses at a lower rate, the difference is not deductible for most employees — the deduction for unreimbursed employee expenses was suspended in 2018, and the One Big Beautiful Bill Act made that permanent from 2026.

Questions people actually ask
- What is the IRS mileage rate for 2026?
- 76 cents a mile for business use from 1 July 2026, and 72.5 cents for the first half of the year. Medical and military moving are 23.5 cents from July and 20.5 before it. The charitable rate is 14 cents throughout, because it is fixed in the statute rather than adjusted for costs.
- Why did the rate change mid-year?
- The IRS sets the business rate from an annual study of the fixed and variable costs of running a car, and issues a mid-year adjustment when fuel prices move enough to make the published rate unrepresentative. It has done so several times, most notably in 2008, 2011 and 2022. Each half of the year is claimed at the rate in force.
- Can I deduct mileage as an employee?
- Generally not. The Tax Cuts and Jobs Act suspended the deduction for unreimbursed employee business expenses from 2018, and the One Big Beautiful Bill Act (P.L. 119-21, §70110) made the suspension permanent from 2026 — it is not coming back. Self-employed people, and employees in a few categories such as armed forces reservists and qualified performing artists, still claim it. Employer reimbursement at or below the standard rate remains tax-free to the employee.
- Standard rate or actual expenses?
- The standard rate covers fuel, maintenance, insurance and depreciation in one figure and needs only a mileage log. The actual-expense method can be worth more for an expensive vehicle driven few miles, but requires receipts for everything and locks the choice for that vehicle in most cases. Whichever you choose, the mileage log is what an audit asks for first.
