Tax on cars and motorcycles is high in Denmark. So goodbye to Germany’s SUV culture, and welcome to the EV world. I did buy a small petrol car though, but those are getting more and more rare. A lot is written about importing your car to Denmark and that it is better to sell it and buy again in Denmark. Well, if you sell something you don’t want to sell, you loose money, and if you buy the same you loose money again. Selling your big SUV and buying a small car in Denmark makes sense and saves money. But that is not a fair comparison, importing is all about keeping the same.
When you import a car to Denmark, you have to pay the amount of tax, that the same car registered in Denmark was taxed with (sounds fair to me). I imported my motorcycle myself. Yes, that was expensive, but definitely not more expensive as buying it used in Denmark. The whole process is actually quite simple, in hindsight (as always). But that’s coming from Germany, with no registration tax. When importing from the Netherlands for example, you have to get the registration tax (“bpm”) you payed there refunded first, otherwise that money is lost.
Let’s do the math: MC new in Germany (2023) with some options: Euro. 11.000. Same MC without options in Denmark (2024 price) 139.995 DKK (equals 18.761 Euro). Valuation in 2024 (just over 1 year old) by danish tax agency: 120.000 DKK, of which 51.221 DKK is tax. So I payed 51.221 (6.864 Euro) registration tax. My total cost: 11.000+6864=17.864 Euro.
The alternative: sell and buy. Selling in Germany, I would get 9.000 (if I’m lucky) for the bike, that’s 2.000 Euro loss. Then buy the same bike in Denmark, 1 year old, with the same options and 4000km? In real life impossible, but to complete the math, let’s say: 17.000 Euro, so 2.000 down from new. Cost in Germany: 2.000 Euro. Cost in Denmark: 17.000, total 19.000 Euro, well over the 17.864 resulting from the import. To be fair, the import-inspection was about 130 Euro, but still importing remains about 1000 Euros cheaper. This is a story about an almost new bike. The math will be completely different for your rare Goldwing with options. Bottom line: importing is not by default the worst option.
Note that you can calculate the registration tax in advance using the tool on the DMR website (motorregister.skat.dk, in danish only). The most important input parameters are: car/bike price new and car/bike value current as shop/street price in Denmark. This makes an estimation difficult if the car or bike is not sold on the danish market. You then have to revert to 2nd hand platforms in Denmark or for example Germany. What you payed (in another country of course) when you bought the car or bike does not matter!
You can check the status of the import process on the DMR website, and all communication is done online using your personal mailbox (E-Boks). One thing that helps a lot, is the online de-registration option in Germany. The process uses peel-off labels that hide codes on your registration papers and your number plate. 
This avoids a catch-22, since you hand in your old registration papers when you get your Danish plates. The de-registration info is automatically passed to the tax authority (“kfz-steuer”) and your insurance company. When it comes to cars, Germany is somewhat digitalised.
There is no recurring inspection (TüV in Germany, APK in the Netherlands) for motorcycles in Denmark, but it has to be inspected when imported. Nothing special for an almost new motorcycle, and the prices are fixed, so no need to stress about the cheapest inspection garage (Synshal). You pay a free for the inspection, an extra fee since this is for import, and (after you have payed the registration tax) a fee for the number plate.
Trust me, my first ride in Denmark with a Danish plate was cold, too short, but very very nice…
