Joint accounts and the £10000 self assessment.

Hi If the total savings interest from 5 joint accounts was say £12000 both people would declare £6000 each. In this case where does the £10000 self assessment come in. Do both people do a self assessment because the total interest is £12000 or do they not have to do self assessment as they are declaring £6000 each which would be under the threshold. Many thanks

Hi Steve72,
As the individual interest is under £10,000, a return is not required.
Thank you.
