Mileage Deduction Calculator 2026
Estimate your 2026 business mileage deduction with the mid-year IRS rate split applied automatically: miles driven January through June count at 72.5 cents each under Notice 2026-10, and miles driven July through December count at 76 cents under Announcement 2026-11. Enter the two totals and see the deduction, the math, and the source the rates come from.
Works offline — your inputs never leave this device. How that works
The IRS revised the 2026 standard mileage rate mid-year: 72.5¢ per mile for miles driven January–June and 76.0¢ per mile from July 1 onward. Enter each half separately so the deduction uses the rate that applied when the miles were driven.
The standard mileage rate covers business driving. Commuting between home and a regular workplace is not business mileage under IRS rules, and the standard rate cannot be combined with actual vehicle expenses for the same miles.
This amount is a business expense: subtract it from gross payouts to get the net profit the self-employment and quarterly calculators ask for.

What it is
An estimate of the 2026 standard-mileage deduction for business driving, built for the unusual year in which the IRS changed the business rate mid-year — 72.5 cents per mile through June 30 and 76 cents from July 1 onward.
How it works
Miles driven January–June are multiplied by the 72.5¢ rate from Notice 2026-10, miles driven July–December by the 76¢ rate from Announcement 2026-11 (both transcribed in the verified mileage-2026 pack), and the two products are added. The medical/moving and charitable rates are shown alongside for reference.
Getting the most from it
- Split the year’s business miles into the January–June and July–December totals.
- Enter each figure — a mileage log or the app’s yearly summary supplies both.
- Read the two period subtotals and the combined deduction.
- Carry the dollar figure into the expense field of the quarterly tax calculator.
Reading your result
The total is the Schedule C deduction the standard-mileage method would produce for those miles. Each period’s subtotal is shown separately so the mid-year rate change stays visible instead of disappearing into a single blended number.
What it can't tell you
It does not compare the actual-expense method, handle depreciation recapture, or decide whether specific miles qualify as business use — the IRS definitions and a contemporaneous log control that. Estimate only; the linked IRS rate table is the source of record.
Frequently asked questions
There are two: 72.5 cents per business mile for January 1 – June 30, 2026 (Notice 2026-10), and 76 cents for July 1 – December 31, 2026 after Announcement 2026-11 raised it mid-year citing fuel prices. A 2026 deduction is computed by date driven, which this calculator does.
