ONSCG9300 - Reviews and appeals: direct tax appealable decisions
It is not likely that direct tax decisions made by clearance teams will carry a right of appeal. There is no direct tax equivalent to section 83(1)(b) [for VAT], and it is unlikely that clearance teams will issue closure notices or assessments, amend returns or refuse claims.
If you are not sure about whether your decision is appealable, contact the Tax Administration, Litigation and Advice team at Caseworker service for technical queries.
