Hello
I plan to move to Lisbon this month and become a resident with the intention to retire. I will rent medium/long term initially until I buy a suitable property. This will hopefully lock-in my rights under the EU/UK Withdrawal Agreement.
When I become a resident in Portugal I understand that I will also become tax resident in Portugal. However, I still have a property back in the UK and according to the UK Statutory Residence Test I am still classified as tax resident in the UK. I understand that I can only be tax resident in one country and based on the PT/UK dual tax treaty and OECD tax rules I would be classified as tax resident in UK (based on days spent in UK/PT and centre of vital interests). So, my questions are as follows:
a) do I need to update my NIF tax status with my PT address and update my tax status from non-resident to PT tax resident as soon as I move to Portugal and let PT/UK tax authorities determine my tax status between them for 2020 and the following years?
b) if I know that my tax residence is UK based on the number of days spent in UK, centre of vital interests etc, do I register with NIF as tax non-resident in PT and just update my NIF details with my PT address.
Appreciate any feedback from someone in the same situation or even better a member with tax knowledge.
Best regards
Embee
