Check your mileage log against what the IRS asks for
Publication 463 asks for the miles, date, destination and business purpose of each business use and the total miles for the year. Milesheet flags the trips that are missing them.
What an adequate record has
Table 5-1 of Publication 463 lists, for car expenses: the mileage for each business use and the total miles for the year, the date of each use, your business destination and the business purpose. It also says you can't deduct amounts you approximate or estimate.
What Milesheet flags
- Business trips with no purpose, or no destination
- Trips with no category, which count toward nothing
- Commute trips (home to a regular workplace is never deductible) — left out and counted
- Possible duplicates, days over 800 miles and odometer readings that go backwards
- No total miles for the year, so there's no business-use percentage
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.
Your trips stay on your computer
Milesheet reads your file with JavaScript in your browser tab. Nothing is uploaded and there's no account. Close the tab and the trips are gone; only your settings (tax year, total miles, name) can be saved in this browser.
How it works
- Drop your trip log (CSV or Excel) — or try the sample, or download the template.
- Pick the tax year, whether you drive as self-employed or an employee, and the car's total miles for the year.
- Read the totals and checks, then print the summary. With Pro, see and print the full log and download the Excel workbook and CSVs.
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.
