The audit that looks closely
The auditor wants a complete mileage log and questions handwritten entries. With a SHA-256 seal per entry, it stays clear that nothing was changed after the fact.

Worried your handwritten mileage log won't hold up when the tax office asks?
Every trip.
Sealed tamper-evident.
A mileage log only counts with the tax office when it's complete and can't be altered afterwards. TaxDrive keeps your digital mileage log right on your phone: every trip with date, start, destination, odometer reading and purpose, cleanly split into business, private and commute. Each entry gets a SHA-256 seal, and everything stays offline on your device.

What TaxDrive does for your mileage log
Log a trip in seconds
Date, start and destination address, odometer reading and purpose — typed in fast with address suggestions. All local, no GPS tracking.
Business, private, commute
Separate every trip by purpose. TaxDrive adds up the miles automatically and records every required detail.
SHA-256 seal per entry
Every trip gets a SHA-256 checksum. Later changes become detectable — so the mileage log is accepted.
Export as PDF and CSV
A clean mileage-log PDF or a CSV file for your accountant and the tax office, with all trips, miles and checksums (one-time purchase).
Why a tamper-evident mileage log matters
A mileage log is only accepted by the tax office when it's kept promptly, without gaps, and can no longer be altered afterwards. That's exactly where loose notes and spreadsheets fail: they can be changed at any time, and in a dispute it's your word against the auditor's. TaxDrive closes that gap by giving every trip a SHA-256 seal the moment you save it.
You record every trip with date, start and destination address, odometer reading and purpose, then classify it as business, private or commute. TaxDrive adds up the miles automatically, manages several vehicles with number plates, and keeps every required detail together. At year end you create a mileage-log PDF or CSV file for your accountant in a single tap.
All trips stay solely on your device. No account, no server, no cloud, no GPS tracking. TaxDrive documents your trips and prepares them for your tax return; the app is not a substitute for tax advice.
Three situations drivers know
The company car with private use
Without a clean mileage log, a flat-rate taxation method may apply. Recording business and private trips separately lets you show the actual share.
The note in the glovebox
Handwritten notes get lost or become illegible. Captured on your phone, every trip stays dated, sorted and exportable as a PDF at any time.
All three situations share the same pattern: a mileage log is only worth as much as its proof. With a complete, sealed mileage log, every trip stays verifiable when the tax office asks.
Frequently asked questions about the mileage log
Is a digital mileage log accepted by the tax office?
A mileage log must be kept promptly, without gaps, and unalterable afterwards. TaxDrive seals every trip with a SHA-256 checksum so later changes become detectable — so the mileage log is accepted.
What does the SHA-256 seal mean?
When you save, TaxDrive computes a SHA-256 checksum for each entry. If the entry is changed later, the checksum no longer matches. That keeps it verifiable that the mileage log was not manipulated after the fact.
Does TaxDrive work without internet?
Yes, the app works 100% offline. All trips stay solely on your device. No account, no registration, no cloud, no GPS tracking.
Can I export the mileage log?
Yes. In a single tap you create a mileage-log PDF or a CSV file with all trips, miles, purposes and checksums for your accountant and the tax office (one-time in-app purchase).
Can I manage several vehicles?
Yes. You add several vehicles with number plates and record odometer readings and purposes separately. Business, private and commute trips are totalled automatically per vehicle.
