I should have reclaimed savings interest on my tax return, is it to late?

It was off a ppi refund and they paid it automatically but it was £300 and I should have claimed it back on the last return.

Is it too late.

I believe you are allowed to make amendments to your tax return up to a year after the deadline, e.g. for the 2019/2020 return the deadline was 31 January 2021, so you can make amendments any time before 31 January 2022.

Not sure what you mean. Were you taxed on your interest?
