Debt and return pursuit: tax credits overpayments: general: IDMS/NTC discrepancies: NTC not updated IDMS - overpayments and updates

Because of a number of NTC/IDMS interface problems you may find that:

  • an overpayment shown on NTC as having been referred to IDMS is not on IDMS
  • payment/remission postings have not updated IDMS
  • an overpayment is cleared on NTC but is still outstanding on IDMS
  • the amount of the overpayment on IDMS is different to the amount on NTC but is not covered by the first two bullet points.

Where you encounter any of the above you can amend IDMS to bring the two systems into line. You will need to take into account the stage that the recovery process has reached and whether the claimant needs to be advised.

In addition, you may find pre-release 9 ‘HATS’ on household notes. These can be identified by the following text:

^^^^^Debt Recovery action suspended whilst dispute is investigated OD20.

If you encounter a case with such a note, you will need to contact DOP staff at TCO by using your office’s nominated contact and ask them to delete this text. TCO will replace it with the following message, allowing NTC to update IDMS automatically:

OD19 - **SUSPEND O/P RECOVERY** Dispute action complete. Overpayment recovery suspension has been lifted.

If you have any discrepancies that are not covered by the above guidance, you should notify the DM Early Intervention Tax Credit Team and suspend further action whilst the problem is investigated.
