The phrase "Tax Administration requirements" comes up often around mileage registration. In essence it is about your administration being watertight: complete, verifiable and logically correct. Which details typically belong in it are set out below.

Educational in nature, not an official source. This overview is general and meant to get you started. The official and current requirements, terms and conditions are with the Dutch Tax Administration. For your own situation, that information or your adviser is leading.

What does a watertight registration mean?

Watertight means that your administration has no gaps and that the data adds up. Odometer readings run on logically, every trip is recorded and the classification (business, private or commuting) is traceable. A watertight registration is easier to substantiate than an administration with missing trips or illogical readings.

Details about the vehicle

A mileage registration typically contains a number of fixed details about the vehicle, such as:

  • Make and model of the car;
  • The licence plate;
  • The period the administration relates to.

Details per trip

Per trip, the following details are typically recorded:

  • The date of the trip;
  • The start and end odometer reading;
  • The departure and arrival address;
  • The route driven, if it differs from the most usual one;
  • The character of the trip: business, private or commuting.

If you deviate from the usual route, for example due to a diversion or a stop, it is wise to note the reason. That keeps the registration traceable. Read more about that classification on business or private driving.

How long to keep records?

For a tax administration there is a legal retention obligation in the Netherlands. A term of seven years is often mentioned, but the precise term and conditions can vary per situation. For the term that applies to you, rely on the current information from the Tax Administration or consult your adviser.

Where do you find the official requirements?

The official and current requirements are on the website of the Tax Administration. This page is a general, educational aid and not a replacement for it. If you are in doubt about your situation, it is wise to contact the Tax Administration or your own adviser.

An automated solution can help meet that completeness, because trips and odometer readings are recorded automatically instead of copied over by hand. RitGenie records trips automatically and keeps the details per trip.
