Thanks @David_Rosemont for posting the advice / opinion you received. Much appreciated.
When you said “the effect of Brexit on income from British property and investments” was the advice specifically for both rent income and capital gains tax? And also was it specifically shares or also for savings interest?
I see there’s been a bit of discussion here about rent etc but I don’t think the specific scope of your phrase was exactly specified - did your advocat specify scope of income in more detail than you did in your post?
Also I recall @JoCo has posted that he’s in the process of challenging the tax authority on this very matter, albeit for capital gains and would report back, so I’ve tagged him as info on here might be of interest to him.
I think he posted in this thread -
