Pre-enforcement: coding out: Self Assessment (SA) and Tax Credit (TC) overpayments: IDMS campaign
Debts suitable for coding out will be identified by an IDMS campaign. The campaign will be for one Head of Duty (HoD) only. IDMS may select one IDMS work item or combinations of IDMS work items (SA work items only or TC work items only) up to the value of £17,000.00. These debts will be segmented separately and prepared for a coding out campaign.
It is possible that an SA campaign will take place followed by a tax credit campaign; if a taxpayer has both SA and TC debts, both could be coded out, but in separate campaigns, to the maximum value of £17,000.00 per taxpayer NINO.
For more information, see the DMB campaigns intranet site (click on Campaign Plans then Tax Credit Campaigns Plan).
