interest declare or not for amount under £1000 for self-employed

As an self-employed with annual income less than £15000, do I need to report and fill in the UK interests section in the self-assessment for my saving accounts when the total is less than £1000?

Hi
If you use your personal savings account to manage your business transactions, then the interest from the savings account would be shown on SA100 under tax interest or untaxed interest on page TR3 of SA100.
