If you will be working both in Denmark and outside of Denmark, it is necessary to apply for a residence and work permit so that you can travel to and from Denmark without limitations.
If you are a citizen from a country outside Scandinavia, the EU/EEA or Switzerland, you must apply for a residence and work permit in your home country through a Danish embassy or a Danish consulate general before coming to Denmark, even if you will not be living in Denmark during your employment. This applies even if you are from a visa-free country and do not need an entry visa to travel to Denmark (for tourism). The residence and work permit must be granted before you travel to Denmark for work.
The International Staff Office will start the application process once your contract has been issued and will then inform you of the following process.

Working in multiple countries will also affect your tax liability.
You will be fully liable for tax in Denmark on the days you perform work in Denmark. It is therefore necessary that you inform us each month of with the exact dates you have worked in Denmark and outside of Denmark for that same month. The report must be submitted no later than the 15th of each month by sending an email to loen@sdu.dk.
Please be aware that tax is a personal matter, and ISO cannot advise you regarding personal tax. It is therefore recommended that you contact SKAT and your local tax authority.

It is also mandatory to apply for a Danish personal tax number (Danish TIN number) if you will have working days in Denmark.

Tax Identification Number (TIN)
If you will not be residing in Denmark during parts of or for your entire employment with SDU, you must report your international TIN to SDU. This also applies if you will be posted outside of Denmark during your employment.
It will not be possible for the SDU salary administrations office to process your salary until the TIN is reported. The Danish Tax Administration is required to send information to your country of residence, which is linked to your TIN. The State’s Salary System will therefore automatically stop the salary processes if the TIN report is incomplete.
-
TIN stands for Tax Identification Number. It is equivalent to the Danish CPR number or Steuerliche Identifikationsnummer in Germany.
The OECD has created an overview explaining each country’s name and rules regarding the TIN.
The TIN is issued by the country of residence and must be obtained by you, the employee, to pass on to SDU.

In November 2023, the Danish Tax Agency (Skattestyrelsen) and the Danish Agency for Public Finance and Management (Økonomistyrelsen) announced that from 1 January 2024, the State’s Salary System (Statens Lønløsning), and thus SDU, must report the TIN for all international-resident wage and pension recipients.
Employees who are not registered with an address in Denmark are considered international residents and must therefore report their TIN.
-
If you have not reported your TIN when filling out the personal data form, you must report it manually.
The TIN must be reported directly to the SDU salary administrations office (SDU Løn) via e-mail to loen@sdu.dk with the subject 'Faculty – Reporting of TIN no. – name of employee'.

If you are an EU citizen, working full time at SDU, you are covered by the Danish social security system. In Denmark, social security is financed through taxation. If you are working from abroad, this may influence your coverage, and it is therefore important that you contact the ISO to have your status clarified. If you have socially security in another country, SDU may have to pay a contribution to this country.
