AI confidence in this short overview: high
This appeal concerns HMRC discovery assessments (2018/19–2022/23) and a closure notice (2023/24) reducing the Appellant’s claimed car travel expenses. The Tribunal held the enquiry, discovery assessments and closure notice were valid, found the Appellant acted carelessly by failing to keep contemporaneous records and making inconsistent large claims, treated London (within the M25) as her permanent workplace under an area‑based test so Colchester–London travel was ordinary commuting and not deductible, and upheld HMRC’s revised mileage figures; the appeal was dismissed and additional tax of £25,844.45 stood.
Ratio decidendi
This summary is intended to identify the ratio decidendi, meaning the legal reasons for deciding and the binding part of the decision.
AI confidence in this ratio decidendi summary: high
The decision identifies that (1) a discovery under s.29 TMA can validly follow from information obtained in an enquiry showing prior returns lacked contemporaneous records, that large home‑to‑work claims were repeatedly treated as deductible, and that claimed amounts cannot be reconciled with supporting evidence; and (2) where employment requires recurring attendance across a defined geographic area, s.339(8) ITEPA permits treating that area as the employee’s permanent workplace so travel from home outside the area is ordinary commuting and not tax‑deductible.
Obiter dicta
This summary is intended to identify obiter dicta, meaning observations made by the way that were not necessary to deciding the case and are not binding.
AI confidence in this obiter dicta summary: medium
The Tribunal commented that informal advice from an HMRC officer would not override the statutory tests for deductibility and does not absolve the taxpayer’s duty to keep records and ensure returns are correct. It also criticised failures in preparing the hearing bundle (omissions of relevant HMRC notes and returns) while noting such shortcomings do not necessarily prevent the Tribunal reaching reliable findings where sufficient evidence exists.
