I would like to suggest to Monzo to re-design the interest summary = certificate of interest received that is currently issued to customers.
The paper is just far too simple. It does not even include the account number or sort code. It is not obvious what is interest taxable what is an ISA.
Other providers clearly state in like a table form the numbers.
If say I need to give my certificates to my accountant to prepare a tax return, they always require additional bank information.
Thank you
