IRS standard mileage rates for business use
| Period | Rate |
|---|---|
| 2025, full year | 70 cents1 |
| 2026, January 1 to June 30 | 72.5 cents1 |
| 2026, July 1 to December 31 | 76 cents1 |
The IRS announced 72.5 cents for 2026 in Notice 2026-10.2 It raised the business rate to 76 cents for travel on or after July 1, 2026, in Announcement 2026-11.3 The rates in this table are the ones the calculator uses. The IRS standard mileage rates page lists any later change.
As an illustration only, 200 business miles in March 2026 would be 200 times 72.5 cents, or $145.00. The same 200 miles in September 2026 would be 200 times 76 cents, or $152.00. These are sample numbers, not a prediction of any amount for any person. For what the IRS says about which driving counts, see the IRS standard mileage rates guide for sourcing trips.
What the IRS says about mileage records
Topic no. 510 says expenses are substantiated by adequate records or by sufficient evidence that supports the taxpayer's own statement.4 Publication 463, chapter 5, lists for each business use of a car the mileage, the date, the business destination, and the business purpose, along with the total miles driven for the year.5
The same publication describes "timely kept records": a record made at or near the time of the use is more valuable than a later statement, because memory is less accurate over time, and a weekly log covering that week's use counts as timely.5 A log kept as trips happen is what people usually mean by a contemporaneous log.
The template below follows those elements: date, destination or stops, business purpose, and odometer readings with the miles for each trip. It includes one sample row to show the format. Replace it with your own trips. Whether a record is adequate for your situation is a question for a qualified tax professional.

Sourcing trips in the app
Strooply logs sourcing trips and estimates mileage at the IRS rate. Sourcing trips, on Pro and Team plans, group a buying trip's stops, items, receipts, and mileage in one record, and mileage tracking is available on Pro and Team plans. Strooply can estimate driving distance from the home address and the trip's stops, or miles can be entered manually, and it prices each trip at the IRS rate in effect on the trip's date.
Trip records in Strooply are not a substitute for a contemporaneous mileage log. Confirm the current rate at irs.gov.
Strooply is record-keeping software. It does not prepare or file tax returns, refund claims, or other filings, it is not a tax preparer, and its figures are estimates to check against your own records.
Mileage calculator questions
How do I estimate sourcing trip mileage?
Multiply the business miles for a trip by the IRS standard mileage rate for the date of the trip. The calculator does that with the rates in the table on this page, and the result is an estimate for illustration.
Which IRS rate does the calculator use?
The IRS business standard mileage rate for the period you pick. A year with a mid-year change, such as 2026, has two periods, and each trip uses the rate for its date. The rates come from the same table Strooply uses to price trips in the app. Confirm the current rate on the IRS standard mileage rates page.
Does this show what I can deduct?
No. The result is miles multiplied by a rate, an estimate for illustration. It is not a determination of any deductible amount for any person. How mileage appears on a return depends on the facts, and a qualified tax professional can advise.
What does the IRS say a mileage record includes?
IRS Publication 463 (chapter 5, Table 5-1) lists the mileage for each business use of a car and the total miles driven for the year, the date of each use, the business destination, and the business purpose. The publication also says a record made at or near the time of the use is more valuable than a statement made later, and that a weekly log covering that week's use counts as timely.
Can I use the log template for a trip I already took?
You can fill it in for past trips, but the IRS describes records made at or near the time as more valuable than later reconstructions. Entering each trip soon after it happens, as the template is designed for, follows that description.
Does Strooply replace a mileage log?
Strooply logs sourcing trips and estimates mileage at the IRS rate. Trip records in Strooply are not a substitute for a contemporaneous mileage log. Confirm the current rate at irs.gov.
