For the first time my interest income from savings will be above my PSA but below £10k, I assumed that this would automatically be confirmed to HMRC as previous years below my PSA are shown on my online account but no tax was needed, however for 23/24 I've been sent a Bank and Building Society Interest (BBSI) form for completion. My 23/24 PAYE income tax summary is not currently available online so I can't see what has been reported. As I use a savings platform I haven't actually got the individual account details just the total interest received for the year, do I need to complete this form? I also received stock interest from gilts, will this be automatically be reported to HMRC or do I have to do this myself? If so how is this done as I can't see an option on the online account for reporting this.
