Please could I get some advice and guidance in regards to my situation?
I am a veterinary surgeon currently employed part time via PAYE and working ad hoc shifts on a self employed basis in the UK. I therefore file a tax return every year. I have been recently offered to work some ad-hoc locum shifts in Norway.
I am aware of the double tax treaty between the UK and Norway, however I could not find any guidance on what steps to follow to get started.
My questions are:
1. Should I apply for a tax exemption in Norway in order to pay my tax solely in the UK?
2. What if I stay in Norway more than 183 days in a tax year, but I am registered in the UK for tax purposes (PAYE job, mortgage)? Do I need to report my earnings to the Norwegian tax office, but continue to pay my tax in the UK?
3. Can I continue to pay my taxes in the UK for my UK jobs and pay my taxes in Norway for my self employed earnings in Norway separately or do I always pay my taxes in one country at a time? Would I need to fill a tax return in each country and mention the foreign income from both?
I will be very grateful if I could get any clarification on those.
