Hi Andrew,
If you remain resident and ordinarily resident for UK tax purposes, the likelihood is that you will have to pay UK tax on your worldwide income, but claim a credit for overseas tax against your UK tax liabilty (but see below).
Where the same income (in your case employment income) is liable to tax in more than one country, relief for the double tax will be given either under the provisions of a double tax treaty or unilaterally.
You will need to check whether a double tax treaty exists between the UK and the country where you have been working. If a treaty does exist, you will need to establish whether the treaty specifies that double taxation is eliminated through exemption of your income. Where the exemption method is not detailed in the treaty, your income will be charged to UK tax, but a credit will be given for the lower of the overseas tax and the UK tax.
If a treaty does not exist, unilateral relief can be claimed against the UK tax at the lower of the overseas tax and the UK tax.
We hope this helps as a starting point for you.
