It sounds simple. Take a few photos, put up a listing, and rent out your flat while you are away anyway. And it really can add a nice bit of income. But in Copenhagen there are a couple of rules you need to get straight first, or a good idea can quickly turn into a fine.
The first step has nothing to do with photos or prices. You can only short-term rent a home you live in yourself, meaning your year-round home with your registered address. If you live in an owner association or a housing cooperative, check the bylaws and house rules before you do anything at all. A cooperative can restrict or fully ban short-term letting. If you rent your own home, you need your landlord's permission.
In Copenhagen you may rent out your year-round home for a maximum of 70 nights a year. A municipality is allowed to raise the limit to 100 nights, but Copenhagen has chosen to keep it at 70. From 2026, the City of Copenhagen has set aside nearly four million kroner for a housing patrol of 15 staff who actively look for illegal letting, and fines can reach as much as 100,000 kr if you go over.
The tax is easier than people think. Airbnb reports your rental income to the Danish tax authority automatically, and that is why you get the higher allowance: 35,100 kr tax free in 2026 through a reporting platform, against only 13,800 kr if you rent privately. Of the amount above the allowance, 60 percent is taxable as capital income. Then comes the practical side: clean thoroughly, fit a working smoke alarm, lock valuables away, check with your insurer, and take 15 to 25 good daylight photos, because the first photo decides whether people click on your listing at all.
