You are usually required to be nationally registered where you are studying
If you move to study at a university or college, you are usually required to be nationally registered in the municipality where you are studying. Where one is required to be nationally registered is steered by Folkbokföringslagen (the Swedish Population Registration Act, SFS1991:481).
Students who have a TV receiver and are registered in the municipality where they are studying are required to pay their own radio and TV fee (even if you are subletting a flat). Students under 18 and are attending upper secondary school (gymnasiet), are considered as living at home as a part of their parents’/legal guardians’ household, even if they are studying elsewhere.
Boarding houses and students´ hostels
If a company has a boarding house/students’ hostel, such as a student corridor, and the company has provided a TV receiver in a common assembly rum, it is the company who is required to pay the radio and TV fee for this TV receiver.
