Hi akquestion
If you do not complete a Self Assessment then the bank/building societies report the interest details to HMRC after the tax year end. Once received HMRC will review your PAYE record and if tax is due a calculation will be issued to you.
Thank you.

Hi ACTS
It depends if the refund was from HMRC as an in year refund or from your employer through your wages. If you contact HMRC we can check this and advise. Self Assessment: general enquiries
Thank you.
