Paying tax on interest NOT via tax code

I want to pay tax on bank interest without it appearing in my tax code. How can I arrange to do that?

Hi,
If there is tax due on your untaxed interest then once your PAYE records are reviewed a calculation will be issued.
Once received you can contact HMRC for details on how to make a direct payment:
