DE 7: Logbook requirements
or “Rules for keeping a vehicle logbook for business use”

You could also call this:

“Time period for measuring business use of a vehicle, lasting up to 3 years”

A logbook term is a time period that shows how much you use your car for business. This term can last up to 3 years.

The logbook term starts on the latest of these days:

  • The first day of the tax year when you begin keeping a logbook
  • The day you get the car (unless it’s a replacement car, which is covered in section DE 11)
  • The day after your last logbook term ended
  • A day you choose

The logbook term ends on the earliest of these days:

  • The day you sell the car without getting a new one
  • 3 years after the first day of the tax year when the logbook term started
  • A day the Commissioner chooses under section DE 9
  • A day you choose

This helps you figure out how much of your car use is for business over a set period of time.
