VDIM9090 - Circumstances affecting default interest: Bulk period assessments
This guidance deals with interest matters in respect of prescribed accounting periods starting on or before 31 December 2022. Interest matters with effect from 01 January 2023 are dealt with under Finance Act 2009.
Please see Compliance Handbook page CH140000 onwards to find the new interest rules guidance.
An Officer’s Assessment raised in an evasion case may include periods more than 4 years old which are processed as a bulk assessment (period 00/00), however the computer does not recognise period 00/00 and so cannot calculate interest for this period.
You will need to increase the amount of tax liable to interest through the VAT663 procedure provided another under declaration has been processed on the same VAT641 / VAT642, see VDIM6000.
