My client wants to pay his January 2021 tax bill by 12 monthly instalments. When he tries to do this online it is including not only the balance outstanding from 31/1/21 but also the estimated POA due on 31 July 2021. He phoned HMRC and they confirm that this should be included in setting the level of instalments.
This is not what I understood would happen and I can't see anything regarding this in the guidance. Is this how other people expect the instalment plan to work?
For my client with zero income and only the SEISS grants to rely on, adding £100 to his monthly instalments for a sum that is not yet due is tough to swallow.
