You do not have to pay registration tax, and if your trailer weighs 500kg or less, you do not have to pay vehicle weight tax either.

If the total weight of the trailer exceeds 500kg, you will be charged vehicle weight tax. If your trailer has a number plate, you can see the specific weight tax in the Danish Register of Motor Vehicles. If the trailer has no number plate, but you know the total weight of the trailer, you can see the tax rates in Danish in our legal guide.

Vehicle weight tax etc. (our legal guide)

Most often you can buy a trailer fitted with a number plate. Trailer dealers may also be number plate providers. If not, you can buy your number plates from a number plate provider (in Danish only but enter your town or postal code to find the one nearest to you) or in one of our vehicle registrationy offices.

Trailers only need one number plate, and the price of such a number plate is DKK 590.

We charge a processing fee of DKK 200 if you buy the number plate in one of SKAT's motor registry offices. The fee charged by number plate providers vary.

You can deregister your trailer with a number plate provider (in Danish only but enter your town or postal code to find the one nearest to you) or in one of our vehicle registration offices where you hand in your number plate.

This also applies if you have scrapped the trailer. You cannot deregister the trailer in the register of motor vehicles. We charge a fee of DKK 60 to deregister the trailer in one of our vehicle registation offices. Number plate providers are free to decide if they want to charge a fee for deregistering a trailer.

You can re-register your trailer in three ways:

Please bring the following:

  • Registration certificate
  • Photo ID
  • Power of attorney if you represent somebody else

If the trailer weighs less than 3,500 kg, it needs to undergo an inspection in the event of re-registration. However, an inspection is not required if the first registration was made:

  • less than five years ago
  • between 5 and 10 years ago, but the trailer has undergone an inspection within the past 2 years
  • for more than 10 years ago but the trailer has undergone an inspection within the past year.

The trailer does not need to be inspected if a change of ownership has taken place between spouses or cohabiting partners WHO have lived together for the past 5 years. For further reading in Danish on inspection of vehicles (The Danish Road Safety and Transport Agency).
