In connection with starting your employment, you need to send a provisional tax assessment card (Skattesedel) to HR. This can be obtained from the Swedish Tax Agency (Skatteverket).

If you are relocating to Sweden or if you in addition to Örebro university have another employer outside of Sweden, you need to contact The Swedish tax agency and register for preliminary A-tax, or to apply for special income tax for non-residents (SINK). The Tax Agency needs to reach a decision on whether you should pay preliminary A-tax or SINK so that Örebro university can deduct tax accordingly. Inform HR about the decision.
When you visit a service center to apply for a personal number and have not yet registered for A-tax or applied for SINK, you should be able to apply there.
You can start your employment before the Tax Agency has reached a decision on A-tax or SINK.
SINK
If you will be staying in Sweden for a short period, less than 6 months, you can apply for special income tax for non-residents (SINK). Read more about SINK at Skatteverket. Contact lonesupport@oru.se if you have questions.
