Declaring foreign earnings

I have some income from a University overseas and have declared the full amount in the foreign earnings section but when the calculation is done I appear to have only been taxed on mu UK earnings. Do I have to repeat the amount in the main income section, even though the overseas source won't have a UK tax reference number etc?

Hi ChrisG,
No, you do not need to declare on the main tax return.
If you think your calculation is incorrect you will need to contact HMRC to review:
