SAM2080 – Amend payment: amend payments on account: interest and RPS consequences


When you transfer all or part of a specific payment that is allocated to a charge you will trigger a re-allocation if

  • There is a credit balance on the record and / or
  • The transfer will result in the discharge of a paid interest charge

The reallocation causes the system to consider whether any interest liability and / or repayment supplement (RPS) arises. This action can disadvantage the taxpayer. Where you

  • Identify that the taxpayer has been disadvantaged, or
  • Receive an objection because of the interaction of interest and RPS

refer to ‘Payment allocation and transfer’ ( SAM80050) and then the Debt Management and Banking Manual (DMBM).

For an explanation of how interest and RPS is calculated see:

Re-allocation and RPS

Re-allocation and interest

When a payment is re-allocated to a charge a review of the interest position takes place automatically.

Review of the interest position

An interest charge is created if an interest bearing liability is cleared and payment was made late. The due date of the interest charge is the date it was created. The automatic payment allocation rules make use of this due date to determine the allocation of the next payment credit.

A review of the interest position can also cause an interest charge to be discharged where, for example

  • The related SA liability is increased or
  • A payment which cleared the SA liability is returned or (part) transferred

Where following a review interest is discharged, a fresh interest charge is raised when the full liability is cleared. For more information see section ‘Interest’ ( SAM60000).

Re-allocation

In the case of an unallocated amount any interest is calculated from the relevant due date of the charge to the effective date of payment (EDP) (see SAM60055).

Where the amount re-allocated is an overpaid amount, up to 28th January 2000 any interest was calculated from the Relevant Due Date (RDD) of the charge to the date of re- allocation.

If re-allocation of an overpaid amount took place after the RDD of the charge, the taxpayer was given RPS and charged interest for the common period which ran from the later of the RDD or EDP to the date of re-allocation.

From 28th January 2000, where an overpaid amount is re-allocated, the system uses the EDP for calculation of RPS. This will only be given if the taxpayer makes payment earlier than the RDD of the charge. Interest is also calculated from the RDD of the charge to the EDP of the overpaid sum. This avoids a common period arising for RPS and interest.

Re-allocation and RPS

Whenever an overpaid amount is re-allocated, the system calculates any RPS for a qualifying payment and shows the amount on the taxpayer record.

Prior to 28th January 2000, when an overpaid amount was re-allocated, RPS was calculated from the effective date of payment (EDP) to the later of the Relevant Due Date (RDD) and the date of re-allocation. Where re-allocation took place after the RDD, the taxpayer was given RPS and charged interest for the common period which runs from the later of the RDD and the EDP to the date of re-allocation.

The amount on which RPS has been calculated can be identified using function VIEW STATEMENT. The RPS start and end dates normally equate to the effective date of payment and the posting (‘Created’) date respectively of the corresponding re-allocated amount on the taxpayer record.

Note however, that the posting (‘Created’) date of the re-allocated amount does not correspond with the RPS calculation end date where a re-allocation to a charge with a future RDD is involved because RPS is calculated to the future RDD.

A balancing charge credit (BCC) has an effective date of payment (EDP) that corresponds with the filing date, normally 31 January after the end of the tax year. RPS applies from the EDP whether the BCC was allocated to a charge or not.

From 28th January 2000, where an overpaid amount is re-allocated, the system uses the EDP for calculation of RPS and so this will only be given if the taxpayer makes payment earlier than the RDD of the charge.

No RPS is due in respect of an unallocated amount.

For more information about RPS see section ‘Repayment Supplement’ ( SAM111000).
