2026 has two business standard mileage rates. This prices every mile at the one in force on its own date, instead of running the whole year at a single number and getting both halves wrong.

If you only have a start and end odometer reading for the year, you need one more number: the reading on June 30. Without it the split is a guess, and guessing is the thing this page exists to stop.
Date first, then miles. 2026-07-01, 61.8 or 07/01/2026 61.8 or tab-separated all work. Blank lines and a header row are skipped.

Source: Internal Revenue Service, Standard mileage rates, read 2026-10-13. First-half rates announced in IR-2025-128 and Notice 2026-10; second-half rates in IR-2026-29. This calculator computes the business figure only.
The rate is not a property of the tax year. It is a property of the day the mile was driven. A 100-mile delivery day on June 29 is worth $72.50 and the identical day on July 1 is worth $76.00. There is no averaging, no weighting by when you filed, and no option to pick the better one.
So a mid-year rate change turns a single annual mileage figure into a number that cannot be right. Run the whole year at 72.5 cents and every second-half mile is underclaimed by 3.5 cents. Run it at 76 cents and every first-half mile is overclaimed by the same amount. On 10,000 miles either error is $350.
This is only the second mid-year change in roughly a decade, which is exactly why so much software and so many spreadsheets still assume one rate per year. If you are using a tool that asked you for a year and a mileage total and nothing else, it is giving you the wrong number for 2026.
It excludes the line and tells you, rather than pricing it at a guessed rate. A 2025 or 2027 date is not a rounding problem, it is a different rate table, and silently folding it into a 2026 total is how a wrong figure ends up on a return looking confident. Unparseable lines and negative mileage are reported the same way.
A mileage total on its own is not a record. The IRS asks for the mileage for each use, the date, the destination and the business purpose, kept at or near the time of the trip. A figure reconstructed in April from memory is the weakest version of this and a contemporaneous log is the strongest.
Full detail on what a record has to contain is in what a mileage log needs, with the IRS publication it comes from.
No. It multiplies miles by the published rate for the period each mile falls in. It does not tell you whether you qualify to use the standard mileage method, whether actual expenses would serve you better, or what you owe. Ask a tax professional before you file.
No. The parsing and the arithmetic are JavaScript running on your device. There is no request, no logging and no storage. You can disconnect and it still works.
No. The standard mileage rate exists instead of itemising your vehicle operating costs, so claiming both for the same miles is double-counting. Which method you are eligible for and which is better for you is a question for a tax professional, not a calculator.
Those are separate from the per-mile figure rather than inside it, so this calculator does not include them and you should not expect the number here to cover them.
Because the 2027 rates are a different table and this page only holds 2026. Pricing a 2027 mile at a 2026 rate to avoid showing you an error would be the wrong answer delivered quietly, which is worse than an error.
MileTruth keeps the log so the split is not something you have to remember. Each trip is stored with its own date and priced at the rate in force that day, business and personal miles are separated by a swipe, and the report totals the periods separately. It is the same lookup this page runs, against a log instead of a paste box.
MileTruth is not released yet. There is no store listing yet and nothing to buy. These calculators are free either way.
