Completion of SA 100

I understand that I need to use the "Foreign" pages if I received interest over GBP 2,000 from overseas during the tax year. In this case, do I need to enter the same amount in Box 3 (Untaxed foreign interest (up to GBP 2,000)) under the heading "Income - Interest and dividends from UK banks and building societies" of SA 100 as well? Or simply report the amount in the relevant "Foreign" page of SA 106 is sufficient? Thank you.

Hi Gloria Leung,
No.  
If you do, you will be duplicating your foreign interest in the SA calculation.  
If you have paid any foreign tax on the foreign interest, then it goes in SA106, no matter the amount and not Box 3 of SA100.
Thank you.
