I've never needed to do this before but a client showed me their PAYE online account with HMRC and there are amounts showing as unallocated credit NIC compensation (which agrees to 3% of the SMP claimed) and then another amount for unallocated credit SMP (which is only about £400 of the £8500 claimed). How do we clear these?
I'm assuming its something to be done within the basic tools software (which is what she uses) and then a submission to HMRC which would sort it. However, it is in a previous year (2017/18) does this complicate matters?
Or can this be sorted by a call to HMRC?
Many thanks in advance.
