Non Resident to resident.

UbonBlue

I have been non resident for many years. I will be in UK from April 4 to August 6, just over 4 months,then I will be back in UK from Jan to March next year, 3 months.
Will I be able to start an ISA on April 5. I have a GIA already, to transfer shares from.
Or will I have to wait until I have over 6 months in the country to open an ISA.
If so, I would star an ISA on the 5th April and then another on the 8th April, or is this illegal.

Once you become resident in the UK for tax purposes you can (with the exception of USA if you retain citizenship - that causes a separate list of issues).  Until then, you cannot.

When will you become resident in the UK for tax purposes?

I suppose it will be after I complete 6 months in the UK. Unless I decide when I get to the UK  and then unexpectedly have to return overseas in August for a few months. My tax return at the end of the 24/25 year will show I have stayed for 6 months or more and thus tax resident.
