RPS and late payment interest (LPI) charges can arise in the same period, for example where the reallocation of a qualifying overpayment for RPS purposes takes place after the relevant due date of the charge to which it is being reallocated. This overlapping period is called the 'common period' and only applies where RPS and LPI charges apply to the same UTR. The 'common period' rules do not apply to set-offs / reallocations from one UTR to another or to a charge under another head of duty.
Where reallocation took place after the RDD, the taxpayer was given RPS and charged late payment interest for the same period which ran from the later of the RDD or EDP, to the date of reallocation.
As a consequence, both RPS and late payment interest arose for the 'common period' which was from the later of the relevant due date and the EDP, to the date of reallocation.
However, in some cases this disadvantaged the taxpayer. Therefore
However, where the set-off / reallocation is to be made to another UTR or charge under another head of duty via OAS, the end date will be the actual date the set- off or reallocation is made
Where you identify that the taxpayer has been disadvantaged, or
receive an objection because of the interaction of RPS and
interest, you should correct the SA record. The correction is to be
made regardless of whether the RPS / interest calculation was
caused by HMRC error or by the input of data notified by the
taxpayer.

Further information about dealing with objections and corrections to RPS / interest is provided in the Debt Management & Banking Manual (DMBM).
