If your only foreign income was untaxed foreign interest (of up to £2,000), put the amount (in UK pounds) in box 3 instead of filling in the ‘Foreign’ pages.
You must put the name of the country where the interest arose in ‘Any other information’ on page TR 7.
If it was more than £2,000, you’ll need to fill in the ‘Foreign’ page.
If this applies you do not need the SA106.
