SDLT Anti-Avoidance Rules

(HMRC Compliance)

Comment: HMRC introduced anti-avoidance rules to close loopholes and prevent exploitation. Despite initial imperfections, HMRC uses GAAR, targeted rules, and DOTAS to combat SDLT avoidance effectively.

Key Points

  • HMRC Anti-Avoidance Tools: GAAR, targeted rules, and DOTAS.
  • GAAR: Targets abusive tax arrangements since 2013.
  • FA 2003 Sections 75A–75C: Specific anti-avoidance rules for SDLT.
  • Targeted Rules: Address specific reliefs and treatments.
  • DOTAS: Requires disclosure of certain tax avoidance schemes.

Main Principles

  • Comprehensive Coverage: GAAR applies to various taxes, including SDLT.
  • Intent Focused: Anti-avoidance rules target arrangements primarily designed for tax advantages.
  • Transparent Transactions: Proper documentation and clear reporting are crucial.
  • Retrospective Measures: HMRC can apply rules retrospectively to address past avoidance schemes.
  • Taxpayer Engagement: Opportunity for taxpayers to challenge assessments and seek professional advice.


Before the introduction of Stamp Duty Land Tax (SDLT) in 2003, it was relatively straightforward to minimise stamp duty costs on property transactions. Effective anti-avoidance rules were difficult to implement for this document-based tax, prompting the shift to SDLT, a transaction-based tax independent of transaction documentation.

The initial SDLT rules had drafting imperfections, leading to structured transactions designed to minimise tax. To combat this, HMRC introduced targeted anti-avoidance rules to prevent the exploitation of specific reliefs and treatments. However, these measures had limited success, leading to the introduction of a general anti-avoidance rule for SDLT on 6 December 2006 under FA 2003, section 75A.

SDLT also falls under the general anti-abuse rule (GAAR) introduced by FA 2013, sections 206–215. Additionally, SDLT is part of the system for the disclosure of tax avoidance schemes (DOTAS), though it has specific rules for what must be disclosed, differing from other tax systems. Disclosures under DOTAS have led to further targeted anti-avoidance provisions, some with retrospective effect, as indicated by the Chancellor of the Exchequer in the 2012 Budget speech. An attempt to challenge these retrospective provisions through judicial review failed (R (on the application of St Matthews (West) Ltd and others) v HMRC, High Court, judgement 6 June 2014).

Key Components

(HMRC Compliance>SDLT Anti-Avoidance Rules)

➤ HMRC uses GAAR, targeted rules, and the DOTAS system to prevent SDLT tax avoidance.

General Anti-Avoidance Rule (GAAR)

  • Introduced by FA 2013, sections 206–215.
  • Applies to SDLT to prevent abusive tax arrangements.

FA 2003, Sections 75A–75C

  • General anti-avoidance rule specific to SDLT.
  • Introduced on 6 December 2006 to address tax minimization strategies not covered by initial rules.

Targeted Anti-Avoidance Rules

  • Specific rules to prevent exploitation of particular reliefs and treatments.
  • These rules remain in force despite the introduction of GAAR and sections 75A–75C.
  • The government indicated that HMRC would first use existing specific rules before relying on GAAR.

Disclosure of Tax Avoidance Schemes (DOTAS)

  • SDLT-specific rules within the DOTAS system.
  • Requires the disclosure of certain tax avoidance schemes.
  • Differences exist between SDLT DOTAS rules and those for other taxes.
  • Continued disclosures under DOTAS have led to further anti-avoidance measures.

Retrospective Provisions and Judicial Review

  • Some anti-avoidance measures have been applied retrospectively.
  • The Chancellor of the Exchequer’s 2012 Budget speech promised retrospective changes.
  • Judicial review to challenge these provisions failed (R (on the application of St Matthews (West) Ltd and others) v HMRC, High Court, judgement 6 June 2014).


The introduction of SDLT and subsequent anti-avoidance rules, including GAAR and FA 2003, sections 75A–75C, have significantly impacted the landscape of property transaction taxation. Despite the existence of a general anti-avoidance rule, specific targeted rules remain active, and HMRC prioritises these before resorting to GAAR. The DOTAS system continues to play a crucial role in identifying and addressing tax avoidance schemes, contributing to the evolution of anti-avoidance legislation.


General Anti-Abuse Rule (GAAR)

(HMRC Compliance>SDLT Anti-Avoidance Rules)

➤ The GAAR targets and prevents abusive tax arrangements, specifically focusing on intent and requiring transparent, well-documented transactions, and is crucial for compliance with SDLT and other taxes.

The General Anti-Abuse Rule (GAAR) is a fundamental part of the UK tax framework designed to counteract tax avoidance strategies. Introduced in the Finance Act 2013, sections 206–215, and supplemented by procedural guidelines in Schedule 43, the GAAR provides HMRC with broad powers to address abusive tax arrangements.

Scope and Application


  • The GAAR applies to a wide range of taxes, including Stamp Duty Land Tax (SDLT). Its extensive coverage means that it can address tax avoidance across various types of tax liabilities, ensuring that abusive practices are curtailed no matter where they occur.


  • The primary aim of the GAAR is to target arrangements whose main purpose is to obtain a tax advantage. By focusing on the intent behind transactions, the GAAR seeks to identify and counteract strategies designed to exploit loopholes in tax laws.

Tax Advantage Definition:

  • Although the definition of a tax advantage is not exhaustive, it includes several key elements:
    • Relief from or Repayment of Tax: This encompasses scenarios where a taxpayer seeks to gain relief from tax or secure a repayment that would not otherwise be due.
    • Reduction, Avoidance, or Deferral of Tax Liability: The GAAR covers arrangements that aim to reduce the amount of tax owed, avoid paying tax altogether, or defer tax payments to a later date.
    • Avoidance of Obligation to Deduct or Account for Tax: It also includes situations where a taxpayer seeks to avoid the obligation to deduct or account for tax that would otherwise be required.

HMRC Compliance and SDLT Anti-Avoidance Rules

HMRC Guidance:

  • HMRC provides detailed guidance on the GAAR, which is accessible on their website. This guidance helps taxpayers understand how the GAAR operates, the types of arrangements it targets, and the consequences of non-compliance.

Focus on SDLT:

  • Given the significant potential for tax avoidance in property transactions, the GAAR has particular relevance to SDLT. HMRC closely scrutinises SDLT transactions to ensure compliance with anti-avoidance rules. This includes examining complex arrangements that might be designed to minimise SDLT liabilities.

Key Considerations for Taxpayers:

  • Intention: Taxpayers must ensure that their arrangements have a genuine commercial purpose beyond merely obtaining a tax advantage.
  • Documentation: Proper documentation and transparent reporting of transactions are crucial. This helps demonstrate the legitimacy of arrangements and mitigates the risk of falling foul of the GAAR.
  • Professional Advice: Given the complexities involved, seeking specialist advice can be essential. Professionals can provide guidance on structuring transactions in a way that complies with the GAAR while achieving legitimate business objectives.


The GAAR is a powerful tool in HMRC’s arsenal to combat tax avoidance. Its broad application and focus on the intent behind transactions make it a critical consideration for anyone engaging in tax planning. By understanding and adhering to the GAAR, taxpayers can ensure they remain compliant and avoid significant penalties.

Key takeaways include:

  • Recognizing the broad scope of the GAAR and its application to various taxes, including SDLT.
  • Understanding the definition of a tax advantage and how it applies to different arrangements.
  • Being aware of HMRC’s guidance and the importance of transparent, well-documented transactions.
  • Seeking professional advice to navigate the complexities of the GAAR and ensure compliance.


HMRC Procedure With GAAR Cases

(HMRC Compliance>SDLT Anti-Avoidance Rules)

➤ The GAAR tackles abusive tax schemes by reassessing transactions, offering taxpayers a chance to respond, consulting a specialised advisory panel, making final adjustments, and addressing specific SDLT avoidance in property deals, ensuring fair tax compliance.

Initial Action

  • Suspected GAAR Application: When HMRC suspects that a tax arrangement falls under the scope of the General Anti-Abuse Rule (GAAR), they will initiate measures to counteract the perceived tax advantage. This involves reassessing the transaction and proposing adjustments to negate any undue tax benefits gained through the arrangement.

Consequential Adjustments

  • Prevention of Multiple Taxation: To avoid the taxpayer being subjected to multiple taxations due to the initial adjustments, they can claim consequential adjustments. This ensures that while the perceived tax advantage is nullified, the taxpayer is not unfairly penalised beyond the intended scope.

Procedural Rules

Notice to Taxpayer

  • Written Notice Requirement: HMRC is obligated to provide a written notice to the taxpayer. This notice must detail the arrangements that HMRC considers abusive and provide reasons supporting this view. This step ensures transparency and allows the taxpayer to understand the basis of HMRC’s concerns.

Taxpayer Response

  • Opportunity to Challenge: The taxpayer is given the opportunity to respond to HMRC’s notice. They can present arguments and evidence to challenge HMRC’s assessment, explaining why the arrangement should not be deemed abusive under the GAAR.

GAAR Advisory Panel

  • Referral to Panel: If HMRC remains unsatisfied with the taxpayer’s response, the case is referred to the GAAR Advisory Panel. This panel, which includes experts, considers representations from both HMRC and the taxpayer.
  • Panel Opinion: The panel will issue an opinion on whether the arrangement constitutes an abuse of the tax system. This opinion helps guide HMRC’s final decision on the matter.

Final Adjustments

  • HMRC’s Decision: Based on the GAAR Advisory Panel’s opinion, HMRC may proceed with making final adjustments. These adjustments aim to eliminate the tax advantage derived from the abusive arrangement.
  • Taxpayer Compliance: Alternatively, HMRC may direct the taxpayer to make necessary adjustments to nullify the tax advantage. This ensures compliance with the GAAR without imposing direct penalties.


  • Right to Appeal: Although not explicitly covered within the GAAR provisions, any adjustments made by HMRC or refusal of a taxpayer’s claim can be appealed. The taxpayer can take the appeal to the Tax Tribunals and, if necessary, to higher courts. This process ensures that the taxpayer has access to judicial review and fair treatment under the law.


Unique Nature of SDLT

  • Transaction Tax Characteristics: Unlike other taxes, Stamp Duty Land Tax (SDLT) is a transaction tax. This means that it is levied based on the occurrence of specific property transactions. Determining whether the main objective of an arrangement is tax saving can be challenging, as the tax is inherently linked to the transaction itself.

Application to Property Schemes

  • Targeting Sub-Sale Schemes: The GAAR’s application to SDLT is particularly relevant for property schemes, such as residential property sub-sale arrangements. These schemes often involve complex transactions designed to minimise SDLT liability.
  • Retrospective Legislation: HMRC has targeted such schemes with specific retrospective legislation, ensuring that past arrangements that aimed to exploit loopholes are also addressed. This highlights the proactive approach taken by HMRC to ensure compliance and curb tax avoidance in property transactions.


Understanding HMRC’s procedure for applying the GAAR is crucial for taxpayers involved in complex transactions. Key elements include:

  • The initial suspicion and action taken by HMRC
  • The opportunity for taxpayers to respond and challenge assessments
  • The role of the GAAR Advisory Panel in providing an impartial opinion
  • The process for making final adjustments and the rights of taxpayers to appeal

For SDLT, the unique nature of the tax and its application to property schemes underscore the importance of careful planning and compliance with anti-avoidance rules. This ensures that taxpayers navigate the complexities of tax legislation effectively and avoid substantial penalties.
