Do I have to declare my Danish income in Sweden? 

If you live in Sweden you must also submit a Swedish tax return, even if all of your earnings are in Denmark. Inform the Swedish tax authorities of your Danish income under "övriga upplysningar" (other information) on the declaration form.


If you have Danish income on which you pay tax in Sweden, you can use the conversion rate of DKK 100 = SEK 137,6 (2018) (the Riksbank's average rate). This applies to people such as Danish employees who live in Sweden and have carried out part of their work in Sweden.
