Hi,
As a tax resident of the UK, who is not domiciled here, you have the option of using the remittance basis, section 9 of RDR1, which will advise of the pros and cons of this method of taxation:
Residence, domicile and the remittance basis: RDR1.
By default, your world-wide income and capital gains, are taxable in the UK, whether it is brought to the UK or not.
The remittance basis only taxes UK income / capital gains and income /capital gains brought to the UK.
Thank you.
