How the calculators work
Social insurance is paid in the work country. Which country taxes the salary depends on the treaty: in some pairs only the work country, in others only the country of residence, often both with a credit. Days worked from home or abroad can move part of the salary to the other country once a tolerance is exceeded. All results are annual and shown in the currency of your country of residence; Swiss francs and Danish kroner are converted at an exchange rate you can change.
