If you have a short-term stay in Greenland due to work, you may be subject to double taxation rules. This depends on which country you were previously tax liable to. Greenland has double taxation agreements with four countries.
You can find the double taxation agreements via this link.

If the country you were previously tax liable to does not have a double taxation agreement with Greenland, you are taxable from the first day.

The Tax Agency has issued a guide for seasonal employees.
You can find the guide here (Danish).

Please note that the deduction rates specified in the guide change from year to year. Current deduction rates are available on the Tax Agency's website under "Announcements." For example, you can find the rates for 2024 here.
