MileageSum exists because 2026 broke every stale mileage table on the internet: the IRS raised the business rate mid-year, so any page showing one number for "the 2026 rate" is wrong for half the year. Every page here shows both periods side by side, cites the IRS notice, and rounds exactly once — the way reimbursement should be computed. Rates verified 2026-07-17.

Frequently asked questions

What is the IRS mileage rate for 2026?

Two rates apply: 72.5¢/mile for business driving January 1 – June 30, 2026, and 76¢/mile from July 1, 2026 (IRS Notice 2026-10 (Dec 2025); IRS mid-year adjustment effective July 1, 2026). Medical and military-moving driving is 21¢/mile; charity driving is 14¢/mile.

How do I calculate mileage reimbursement?

Multiply miles driven by the IRS rate in effect on the driving date. 100 business miles driven in August 2026 = 100 × 76¢ = $76.00.

Why are there two business rates in 2026?

The IRS raised the business rate mid-year, effective July 1, 2026 — only the second mid-year adjustment since 2022. The driving date, not the filing date, decides which rate applies.
