The tax office was very busy yesterday. By the time I got there for a 9am appointment, there were already 10-20 people waiting around.
All I had to do was show my passport and residency card and complete a form. Then I had to wait for them to bring me my letter with my sofinummer. Lucky I took the VVV brochure with me (as I needed a map to find the place), so I sat for almost 45 minutes and read about restaurants I should try.
Health insurance forms are submitted and contract is on way. Almost done with the paperwork
