You must include your income from Denmark that is subject to limited tax liability in Denmark when you calculate the 75% of your total income. Such income from Denmark may be salary, pensions, early retirement benefits, sickness benefits, unemployment benefits, the state education grant (SU), income from self-employment or similar. You subtract any deductible expenses you have incurred in order to receive this income, union membership fees, deduction for transport between home and work or travelling expenses, for example.

Generally, all income is included in your total (global) income. This means that income earned both in Denmark and abroad irrespective of the type of income, interest, dividends, royalties and real property, for example, is included. This income must be included in the calculation of your global income even if Denmark has no right to tax the income according to a double taxation agreement. This could be interest income, pension or the state education grant (SU), for example, from Denmark. Please see our legal guide Den juridiske vejledning C.F.5.3. for further information in Danish about how to calculate the 75% of your total income.

You have two options if you are subject to limited tax liability or if you are a dual resident:

• Subject to limited tax liability/dual residency and not taxed according to the rules for cross-border workers

• Subject to limited tax liability/dual residency and taxed according to the rules for cross-border workers

See various options in Danish related to the cross-border worker rules

If you want to be taxed according to the rules for cross-border workers, you need to inform the Danish Tax Agency (Skattestyrelsen) each relevant year to apply your choice to your preliminary income assessment and tax assessment notice. You need to make your choice for an income year by 1 September (moved from 1 July) in the following income year. You can change your mind about choosing to be taxed according to the cross-border worker rules until 31 August (moved from 30 June due to the corona situation) in the second calendar year after the end of the relevant income year. You need to state that you want to be taxed according to the rules for cross-border workers in your preliminary income assessment and/or tax assessment notice.
