Keeping a mileage log is an essential administrative task that no business owner should overlook. It is an accounting document used to record the operation of vehicles used for business purposes.

A mileage log is a crucial proof tool, allowing business owners to demonstrate that a vehicle is genuinely used for business activities. It is also essential for claiming 100% of fuel costs and plays a key role in accurately determining any private use by employees.

What is a mileage log and why should you keep one

A mileage log records all important details about a vehicle’s operation – date, route, purpose of the trip, kilometers driven, fuel or energy consumption, and the distinction between private and business use.
Keeping a log helps you:

  • distinguish business and private trips,
  • correctly determine the proportion of vehicle use for business,
  • claim the appropriate VAT deduction,
  • gain insight into operating costs,
  • reduce the risk of non-compliance in case of a tax audit.

Changes from 2026 – Mandatory for full VAT deduction

From January 1, 2026, new VAT regulations will make it mandatory to keep a mileage log for claiming a full VAT deduction.
Properly maintained records will therefore not just be a formality but a requirement to prove eligibility to tax authorities.
