What “enactment” means for Land Transaction Tax
For Land Transaction Tax, an “enactment” is a category of law. It is not a stamp duty payment or rate rule. It identifies which laws may matter when an LTT rule refers to legislation.
What this rule is about
Some LTT rules refer to another law. Section 75 explains which types of law may be included by such a reference.
The definition is broad. It includes Welsh and UK-wide laws, together with rules made under them.
What the official source says
The official source states that the term includes the following types of law:
- An Act or Measure of the National Assembly for Wales.
- An Act of Parliament.
- Subordinate legislation made under either of those types of law.
What this means in practice
When an LTT rule refers to legislation, the reference may extend beyond a single document, reaching both an Act and regulations made under that Act. More than one document can therefore matter.
- Do not assume that only the main Act matters.
- Check whether regulations add detail to the rule.
- Check whether the law comes from Wales or Parliament.
How to analyse it
Begin with the precise wording of the LTT rule you are using. Then follow any reference it makes to another law.
- Find the LTT rule that refers to another law.
- Read the Act or Measure it identifies.
- Check for regulations made under that law.
- Use the version that applied at the relevant time.
Example
Suppose an LTT rule refers to a requirement set by an Act of Parliament; if regulations made under that Act set out the detail, they may also fall within the definition. Do not stop after reading the Act.
Why this can be difficult in practice
People often read only the headline Act. Important detail in regulations can then be missed. A document’s title is not enough; what matters is the law that authorised it.
- Regulations may change the practical detail.
- Older Welsh Measures can still be relevant.
- A document may not qualify if it was not made under the right legal power.
Key takeaways
- The term covers Welsh and UK Acts.
- It can also cover regulations made under them.
- Read the main law and any linked regulations.
