VAT Default Interest Manual

When to inhibit, amend or withdraw interest: VAT returns provided at visit

In these circumstances the guidance in VAEC2560 advises that on a visit to a taxpayer an officer should always try and establish the correct VAT liability for periods, by getting the taxpayer to complete outstanding returns in preference to issuing additional assessments.

Where a taxpayer provides an accurate return in such circumstances interest should not be imposed. However if an additional assessment has already been issued any interest will stand.
