Remission of interest: delay cases (Code of Practice)

In accordance with the ‘Code of Practice 1 - Putting things right when we make mistakes’ (CP) interest on tax may be remitted where we have made mistakes or caused unreasonable delays. There is no fixed period over and above our published targets (IHTM02271) for dealing with post when defining the term ‘unreasonable delay’.

The instructions are in two main groups

  • Procedure (IHTM30523)
  • Guidelines (IHTM30524).Note that our decision about remission is not affected by:

  • any delay by the taxpayers or
  • whether or not they have suffered any financial loss attributable to HMRC delay and claim for costs (IHTM02247) incurred as a result.There are separate monetary limits (IHTM30525) for CP cases.
