Mileage deduction calculator for 2026, from your trip log
Drop your mileage log or app export. Milesheet applies the IRS rate for each trip's date — 72.5¢ before July 1, 2026 and 76¢ after — and checks the log the way Publication 463 asks.
Files it reads
A CSV or Excel file with one row per trip: a date and the miles, or odometer start and end. Category (business, medical, charity, moving, commute, personal), purpose, start and end location, vehicle, parking and tolls are optional and recognised by common column names used by mileage apps and spreadsheets. Kilometres are converted if that's the only distance column.
Why one rate for 2026 is wrong
The IRS raised the 2026 business rate mid-year because of fuel prices: trips on or after July 1, 2026 use 76¢, earlier trips 72.5¢ (Announcement 2026-11). A spreadsheet with one rate either over- or under-states the amount. For 10,000 miles, 72.5¢ gives $7,250.00 and 76¢ gives $7,600.00; the right answer depends on when you drove.
| Period | Business | Medical & military moving | Charity |
|---|---|---|---|
| 2026-07-01 to 2026-12-31 | 76¢ | 23.5¢ | 14¢ |
| 2026-01-01 to 2026-06-30 | 72.5¢ | 20.5¢ | 14¢ |
| 2025-01-01 to 2025-12-31 | 70¢ | 21¢ | 14¢ |
| 2024-01-01 to 2024-12-31 | 67¢ | 21¢ | 14¢ |
| 2023-01-01 to 2023-12-31 | 65.5¢ | 22¢ | 14¢ |

FAQ
What does Milesheet do?
It reads your trip log, applies the IRS standard mileage rate for each trip's date and category, totals business, medical, charity and moving miles, adds business parking and tolls, and flags gaps in the records. It doesn't track drives and doesn't file anything.
Is my data uploaded?
No. Your file is read by JavaScript in your browser tab and never sent to us or anyone else. Trips aren't stored, so closing the tab clears them. Your settings (tax year, role, total miles, reimbursement, name) can be saved in this browser.
Which files can I use?
CSV, tab-separated or Excel with one row per trip. A date is required plus miles, kilometres, or odometer start and end. Category, purpose, from, to, vehicle, parking and tolls are optional. Download the template to see the layout.
What's free?
Importing any number of trips, every total including the 2026 rate split, and every check, plus the first 25 rows of the log on screen and in print (with a footer). Pro shows and prints the whole log and exports the Excel workbook and the log and monthly CSVs.
Is everything it totals deductible?
Not necessarily. Business miles go on Schedule C if you're self-employed. Medical miles count only as part of medical expenses on Schedule A, which are deductible above 7.5% of AGI; charity miles only if you itemize; moving miles only for active-duty Armed Forces moves. Employees generally can't deduct unreimbursed mileage.
Is this tax advice?
No. Milesheet applies the rates on the IRS standard mileage rates page (updated July 28, 2026) and rules from Publication 463 and Notice 2026-10 to the data you provide. Ask your tax adviser what applies to you.
