Question:
I am an international student living with my husband or wife, who is here as my dependant - Will we have to pay Council Tax?
Answer:
As a full-time student, you can apply for exemption, provided that you are registered on a full-time course that is expected to last for at least one academic year.
Your spouse can also apply for exemption provided that he or she is not a British citizen and is prevented by the terms of their leave (visa) from taking paid employment or claiming benefits. You will need to show the City Council your spouse's passport as proof of their status.
Council tax is usually payable if you remain in the property between completion of your course and graduation.
