What are my obligations as a cross-border commuter?

After being employed in Denmark you must contact your local tax centre (SKAT in Copenhagen) in order do get a tax number.

You can find you local tax center here:
Skattecenter København

In order for your employer to know how much tax to deduct from your salary, you will need a tax card. The tax card contains information about your withholding rate, deductions and allowances.

Note that the tax card is in electronic form and is also called an e-tax card.

You can request a tax number and a tax card by completing form no. 04.063 from SKAT (available in four languages: English, Polish, German and Danish).

The form can be obtained from your local tax centre or downloaded from SKAT’s website:

You can also contact your local tax centre or one of the International Citizens Services Centres:

Please be aware that you may also be partly liable to pay tax in your home country.
 

If you are here 3 months or less

Your personal tax number works like a civil registration number, i.e. it is your Danish personal identification number.

If you are working here for 3 months or less, you will get a tax number instead of a civil registration number.
 

If you are here more than 3 months

If you are to work and live here for more than 3 months you will have to register with the Danish National Register (Folkeregisteret) at your local citizens services centre before you contact SKAT.

This is in order to get a civil registration number, also known as CPR number. If you have previously worked and/or lived in Denmark, you will already have a civil registration number or a personal tax number.

Information about getting af CPR number at How do I get a CPR number?

Cross-border commuters do not need to apply for a residence or work permit or an EU Certificate of Registration in Denmark.
