Tax on Foreign interest

Hi, I'm a homemaker and have no income in the tax year 2022-23 in UK but received interest from local bank as well as foreign income from interest. May I confirm if: Q1. Does the personal income tax allowance (GBP12,570) covers foreign income such as foreign interest? Q2. Do I have to submit a Self Assessment Tax Return (SA100) on interest received from local banks no matter of the amount (i.e. even a few hundred pounds)? If yes, do I have to fill in SA106 as well for any foreign interest received? Q3(a): Do I have to submit a Self Assessment Tax Return (SA106, FN6) on such foreign interest at around GBP700? 3(b): Do I have to submit a Self Assessment Tax Return (SA106, FN6) on such foreign interest over GBP5000? Looking forward to your reply. Thanks!

Hi corcor, 

Being in receipt of foreign income is criteria for completing a Self Assessment Tax return each year, regardless of how much the income is,
using the official exchange rates and included on the tax return

Foreign bank interest converted to pounds sterling, is added to UK interest and the savings allowance applied in the tax calculation.
