VDIM8040 | How to inhibit, amend or withdraw interest: Setting an inhibit after an assessment is processed

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.

If the inhibit needs to be set on a whole line after an assessment has been processed a VAT643 (assessment amendment form) should be completed.
