Tax situation
I am a retiree from the UK and have lived in Spain for over 5 years and am living in Altea. I have an NIE number and have told the tax authorities that I am a UK resident and use my son's UK address for tax purposes as I want to preserve the advantage of my UK state pension which increases with inflation. Is this allowed and could I be prosecuted for tax avoidance by the Spanish tax authorities? Any advice would be helpful, thank you
