If you are going to rent out your home in Copenhagen, three things decide almost everything: how many nights you are allowed to rent, how much the tax authority takes, and what your association permits. The rest is detail, but those three have to be right.
The 70 nights: in Copenhagen you may rent out your whole primary home short-term for up to 70 nights a year. That applies only if all your letting goes through intermediaries that report your rental income to the Danish Tax Agency, which Airbnb and Booking.com do.
Tax in 2026: you have a tax-free allowance of 35.100 kr, and of anything above it only 60% counts as capital income. The platforms report automatically.
Your association: a housing co-op can forbid short-term letting and often does. A condominium association has a harder time, because banning lets under three months requires every owner to agree.
Here is everything we have written for owners in Copenhagen and Frederiksberg, covering the rules, tax, earnings, pricing, cleaning, insurance, fees, neighbourhoods and how to get started.
