I have a financial question.We are tax residents in portugal.We have a rental flat in the UKon an interest only mortgage which for the last 7 years, we haven't made any income on, as the interest only mortgage and expenses have been more than the rental income. Recently, last year in fact, they changed the law in the Uk to make all income from rental be seen as being taxable, whereas in the past we could offset our mortage expenses against it, but not any more,We obviously do tax returns in each country, but this year, although we have received no income, the Portuguese financas say we owe them tax against that income, even though we haven't in reality had any income from our rental, so we have had a bill for 1,200 euros we weren't expecting.Can anyone comment on this for us, please?
