Building Society etc. Interest

Hello , One of the conditions to register for Self Assessment is if B.B.S.I. exceeds £ 10,000 in a Tax Year . Does the following count towards this figure : 1) Cash I.S.A., Interest ? 2) National Savings Tax Free Certificate, Interest ? 3) Premium Bond Prize/s ? Or can they be ignored when calculating the figure ? Any answers would be very helpful .

Hi
Please note that Cash ISA interest, Premium Bond prizes and Tax Free National Savings are all non-taxable.                                   
Tax on savings interest
Thankyou.
Regards.

Hello , Thank you for your reply . I am aware that the three listed categories are " Tax Free " . My question is do they have to be taken into account when calculating if over £ 10,000 has been received in Interest from UK institutions in a single Tax Year ? To be absolutely clear -- If I received £ 25,000 in Interest from Cash I.S.A.'s in a single Tax Year do I have to register for Self Assessment , yes or no . Thank you for the very much appreciated help you are offering , as a Pensioner I am worried about breaking the law .

Hi Stirling933#,

Interest from an ISA is not taxable and is not declared on a Self Assessment tax return. 

Tahnk you. 

Hi. I very much appreciate the time & effect the two respondents have given to my enquiry . However the question remains ; Do I need to Register ? Thank you .

Hi Stirling933,

The interest from an ISA is not included when looking at the £10,000 limit for interest.
If your interest, other than ISA, is over £10,000 then yes you need to register for self assessment.

Thank you.
