Hi, Im a foreign resident we have owned a property in the uk until recently and completed tax returns each year to declare the income. We have sold the property declared capital gains and submitted the years tax return. Other than this i have a shares isa and a sipp. I will be closing down the shares isa as well. Can you confirm my thoughts that i no longer need to fill in a tax return? Do i submit this via the normal online form?
