Anti-Avoidance Rules for Land Transactions in Wales Before April 2018

Anti-avoidance rules for Welsh land transactions before 1 April 2018

For Welsh land transactions, the key issue is which tax regime applies. If the relevant effective date of the notional transaction is before 1 April 2018, the SDLT anti-avoidance rule in section 75A of the Finance Act 2003 may still apply. For transactions falling under Land Transaction Tax, anti-avoidance is dealt with instead by Welsh rules, including a general anti-avoidance rule and a specific rule blocking abusive relief claims.

• Wales moved from SDLT to Land Transaction Tax on 1 April 2018, so the date of the transaction is crucial.
• Section 75A FA 2003 can still apply to Welsh land transactions where the relevant effective date is before 1 April 2018.
• For LTT transactions, you must look at the Welsh anti-avoidance framework rather than section 75A.
• The Welsh framework includes a general anti-avoidance rule and a targeted rule for relief claims, known as the reliefs TAAR.
• If LTT relief is claimed, an important question is whether the transaction is, or forms part of, a tax avoidance arrangement.
• These rules are not interchangeable, so advisers must identify the correct legal regime before analysing any avoidance issue.

Anti-avoidance rules for Welsh land transactions before 1 April 2018

This page explains which anti-avoidance rules apply to certain land transactions in Wales where the timing falls before 1 April 2018. The main point is that older transactions may still fall under the Stamp Duty Land Tax anti-avoidance rule in section 75A of Finance Act 2003, while later Welsh transactions are dealt with under the Land Transaction Tax regime, including both a general anti-avoidance rule and a specific rule aimed at abusive relief claims.

What this rule is about

Wales moved from SDLT to Land Transaction Tax on 1 April 2018. That change matters because the anti-avoidance rules are not the same before and after that date.

The source material is dealing with a transitional point: if a Welsh land transaction has a relevant effective date before 1 April 2018, the older SDLT anti-avoidance rule in section 75A Finance Act 2003 can still apply. For transactions within the LTT regime, anti-avoidance is instead addressed through Welsh legislation, including a general anti-avoidance rule and a targeted rule for relief claims.

What the official source says

The source states that section 75A applies to a disposal and acquisition of a chargeable interest in land in Wales where the effective date of the notional transaction, as defined by section 75A(6), is before 1 April 2018.

It also states that, under the Welsh regime, there are two separate anti-avoidance mechanisms:

• a general anti-avoidance rule introduced into the Tax Collection and Management (Wales) Act 2016 by the Land Transaction Tax and Anti-avoidance of Devolved Taxes (Wales) Act
• a targeted anti-avoidance rule in section 31 of that Act, referred to as the reliefs TAAR, which prevents a claim to LTT relief where the transaction is, or forms part of, a tax avoidance arrangement

The source therefore distinguishes between the pre-1 April 2018 position, where section 75A may apply, and the post-transition Welsh position, where anti-avoidance is dealt with under LTT legislation.

What this means in practice

The first question is not whether the arrangement looks tax-driven. The first question is which tax regime applies at all.

If the relevant effective date of the notional transaction is before 1 April 2018, the transaction may still be tested under section 75A FA 2003. That is a specific SDLT anti-avoidance provision aimed at arrangements involving land transactions where the tax result is reduced through the structure used.

If the transaction falls within LTT instead, section 75A is not the rule you look at. You instead consider the Welsh anti-avoidance framework. That includes:

• the general anti-avoidance rule, which can apply more broadly to tax avoidance arrangements
• the reliefs TAAR, which focuses specifically on claims to relief from LTT where avoidance is involved

For conveyancers, taxpayers and advisers, the practical consequence is that the date and statutory framework matter immediately. Using the wrong anti-avoidance rule could lead to the wrong analysis.

How to analyse it

A sensible way to approach the issue is as follows.

• Identify the land transaction and confirm that it concerns a chargeable interest in land in Wales.
• Establish the relevant effective date. The source specifically refers to the effective date of the notional transaction for section 75A purposes.
• If that effective date is before 1 April 2018, consider whether section 75A FA 2003 is the applicable anti-avoidance rule.
• If the transaction falls within the LTT period, consider the Welsh anti-avoidance rules instead.
• If relief is being claimed under LTT, ask whether the transaction is, or forms part of, a tax avoidance arrangement, because that may engage the reliefs TAAR.
• Keep separate in your mind the different legal sources: section 75A is part of the SDLT legislation, while the GAAR and reliefs TAAR are part of the Welsh devolved tax framework.

This is mainly a classification exercise at the outset: before analysing avoidance in detail, decide which anti-avoidance code actually governs the transaction.

Example

Illustration: a complex Welsh land arrangement is entered into around the time LTT replaces SDLT. If the relevant effective date of the notional transaction is in March 2018, the anti-avoidance analysis may still need to start with section 75A FA 2003. If a similar arrangement has its relevant LTT timing after 1 April 2018 and includes a claim to relief, the Welsh GAAR and the reliefs TAAR are the more relevant provisions to consider.

The important point is that the location is not enough on its own. The date determines which anti-avoidance regime applies.

Why this can be difficult in practice

The source is brief, but it points to a real difficulty: transitional cases can be technically awkward. In particular, section 75A refers to the effective date of a notional transaction, not simply the date parties may assume is relevant from the paperwork.

There is also a risk of blending together different anti-avoidance rules. A person may refer generally to “anti-avoidance” without distinguishing between:

• the SDLT targeted rule in section 75A
• the Welsh general anti-avoidance rule
• the Welsh reliefs TAAR aimed specifically at relief claims

Those rules are not interchangeable. They come from different legislation and may apply in different circumstances.

Another practical difficulty is that the reliefs TAAR is specifically concerned with whether a transaction is, or forms part of, a tax avoidance arrangement. That can be fact-sensitive. The source does not set out the full test here, so conclusions should not be drawn without checking the underlying Welsh legislation and guidance.

Key takeaways

• For Welsh land transactions, the date is critical: section 75A FA 2003 can still apply where the relevant effective date is before 1 April 2018.
• For transactions within the LTT regime, anti-avoidance is dealt with under Welsh law, including a GAAR and the reliefs TAAR.
• If LTT relief is claimed, one key question is whether the transaction is, or forms part of, a tax avoidance arrangement.
