Discovery Assessments Under Section 29 TMA: Insights from Sanderson v HMRC [2013] UKUT 623 (TCC)

Introduction

The case of David Stephen Sanderson v. HMRC ([2013] UKUT 623 (TCC)) addresses the validity of a "discovery" assessment under section 29(1) of the Taxes Management Act 1970 (TMA). Mr. Sanderson challenged HMRC's assessment, which was made in January 2005 for the tax year 1998-1999, alleging that it was improperly based on a discovery assessment. The core issues revolved around whether HMRC had legitimately discovered an insufficiency in Mr. Sanderson's tax return and whether this discovery was attributable to negligent conduct by Mr. Sanderson or his representatives.

The parties involved were Mr. David Stephen Sanderson as the appellant and The Commissioners for Her Majesty's Revenue and Customs as the respondents. The case was adjudicated in the Upper Tribunal (Tax and Chancery Chamber) on December 6, 2013.

Summary of the Judgment

The Upper Tribunal upheld the decision of the First-tier Tribunal, dismissing Mr. Sanderson's appeal against the discovery assessment. The tribunal affirmed that HMRC had valid grounds to issue a discovery assessment under section 29(1) TMA, determining that the conditions of sections 29(4) and (5) were satisfied. Specifically, it was established that the insufficiency of tax was not due to negligent conduct by Mr. Sanderson, but HMRC had legitimately discovered the insufficiency based on information available after the conclusion of the initial enquiry window.

Analysis

Precedents Cited

The judgment referenced several key cases that influenced the tribunal's decision:

Corbally-Stourton v HMRC [2008] STC (SCD) 907: Provided a detailed explanation of the "Castle Trust Scheme" and its implications for capital gains tax assessments.
Charlton v HMRC [2012] UKFTT 770 (TCC): Clarified the meaning of "discovery" in the context of section 29(1) TMA, emphasizing that no new factual or legal information is necessary for a discovery.
Langham v Veltema [2004] EWCA Civ 193: Discussed the concept of "objective awareness" required under section 29(5) TMA.
With v O'Flanagan [1936] 1 Ch 575: Although not directly related to tax law, it provided an analogy for the duty to correct errors once they are discovered.
WT Ramsay Ltd v IRC [1982] AC 300 and Barclays Mercantile Business Finance Ltd v Mawson [2004] UKHL 51: Established the Ramsay principle, advocating for a purposive approach to statutory interpretation, particularly in complex tax schemes.

Legal Reasoning

The tribunal's legal reasoning was grounded in a meticulous analysis of the TMA's sections 29(1), 29(4), and 29(5). The primary considerations included:

Discovery under Section 29(1) TMA: The tribunal affirmed that HMRC's discovery was valid as the insufficiency became apparent to the officer only in 2004, despite HMRC's prior awareness of the Castle Trust Scheme.
Negligent Conduct under Section 29(4) TMA: The tribunal concluded that Mr. Sanderson acted reasonably and was not negligent. It also reviewed HMRC's cross-appeal concerning alleged negligence by Mr. Sanderson's accountant, Upton Wilson, ultimately finding no merit in HMRC's claims.
Awareness of Insufficiency under Section 29(5) TMA: The judgment clarified that the hypothetical officer must have objective awareness of the insufficiency based solely on the information provided in the taxpayer's return and accompanying documents. The tribunal found that Mr. Sanderson's tax return did not provide sufficient evidence of an actual insufficiency for the officer to act upon.

Throughout, the tribunal emphasized the importance of a reasonable expectation and the limitations imposed on attributing internal HMRC beliefs or information to the hypothetical officer.

Impact

This judgment has significant implications for future tax cases involving discovery assessments:

Clarification of "Discovery": Reinforces that discovery does not require new information but rather the recognition of an insufficiency based on existing data.
Negligence Threshold: Establishes that taxpayers and their advisors must demonstrate reasonable diligence to avoid deductions being attributed to negligence.
Limitations on Section 29(6)(d)(i): Provides a restrictive interpretation, preventing HMRC from attributing extraneous information not provided by the taxpayer to the hypothetical officer.
Purposive Statutory Interpretation: Upholds the Ramsay principle, encouraging courts to interpret tax statutes based on their intended purpose rather than literal meanings, especially in complex schemes.

Consequently, taxpayers can better understand the boundaries of discovery assessments, and HMRC must ensure that any discovery assessment is firmly grounded in the information initially provided.

Complex Concepts Simplified

Discovery Assessment

A discovery assessment is HMRC's power to reassess a taxpayer's liability when they discover that some income or gains were not previously assessed or were under-assessed. Under section 29(1) of the TMA 1970, HMRC can make such assessments even after the usual time limits.

Section 29(4) and (5) of the TMA

Section 29(4): This section stipulates that a discovery assessment can only be made if the insufficiency of tax is due to the taxpayer's or their representative's fraudulent or negligent conduct.
Section 29(5): This limits discovery assessments by stating that if a taxpayer has filed a self-assessment return, a discovery can only be made if certain conditions are met—primarily relating to HMRC being unaware of the insufficiency based on available information.

Hypothetical Officer

The term "hypothetical officer" refers to an imagined HMRC officer with reasonable knowledge and understanding. This officer is used as a standard to determine whether HMRC could have been aware of insufficient tax based on the information provided by the taxpayer.

The Ramsay Principle

Originating from WT Ramsay Ltd v IRC, this principle advocates for interpreting tax statutes based on their purpose rather than their literal wording, especially to counteract tax avoidance schemes that exploit technicalities.

Conclusion

The judgment in Sanderson v HMRC [2013] UKUT 623 (TCC) serves as a pivotal reference point for understanding the scope and limitations of discovery assessments under the TMA 1970. By meticulously dissecting the conditions under sections 29(1), 29(4), and 29(5), the tribunal has provided clarity on how HMRC can legitimately reassess tax liabilities without overstepping into areas of presumed knowledge or negligence.

Key takeaways include:

Discovery assessments can be made based on the information disclosed in the taxpayer's return without requiring new factual or legal developments.
For HMRC to attribute an insufficiency to negligence, clear evidence of negligence by the taxpayer or their representatives is necessary, which was not present in this case.
Section 29(6)(d)(i) must be interpreted restrictively, ensuring that only information explicitly provided by the taxpayer can be used to infer an insufficiency.
The Ramsay principle remains influential, promoting a purposive approach to statutory interpretation to prevent the exploitation of tax loopholes.

Overall, the decision underscores the balance between HMRC's authority to ensure tax compliance and the protection of taxpayers from arbitrary or unfounded reassessments. It reinforces the necessity for clear, honest, and complete disclosures in tax returns and delineates the boundaries within which HMRC must operate when exercising its reassessment powers.
