When Multiple Dwellings Relief Does Not Apply to LTT
Multiple dwellings relief can reduce Land Transaction Tax (LTT) when you buy more than one home at once. But it is blocked in some cases. Land Transaction Tax replaced stamp duty land tax in Wales in 2018. This point can change the tax due.
What this rule is about
The relief for buying more than one home at once is not something you can combine with every other tax break. Some other reliefs take priority. In those cases, multiple dwellings relief is not an option.
Choosing not to claim the other relief does not change that. The same can apply if that other relief is later withdrawn.
What the official source says
The Welsh Revenue Authority says that multiple dwellings relief cannot be claimed if certain other reliefs apply to the purchase. The source also identifies several types of property deal that fall outside the relief.
- Group relief is available for the purchase.
- Reconstruction and acquisition relief is available.
- Charities relief is available.
- The buyer is exercising collective rights and that relief applies.
- The deal is one of the specified leasehold cases.
- A subsidiary home means the main LTT rates apply.
- The purchase involves student halls in further or higher education.
What this means in practice
Before deciding which relief gives the best result, check whether another relief is available, because its availability can prevent you from choosing multiple dwellings relief at all. Do not assume you can pick it. First check whether any of these other reliefs are available. If one is, multiple dwellings relief may be barred from the start.
People can easily miss this point. Not claiming the other relief does not necessarily solve the problem.
- Check all possible reliefs before the LTT return is prepared.
- Tell your conveyancer about connected companies, charities or collective-rights arrangements.
- Flag any long lease or student accommodation early.
How to analyse it
Begin with the whole deal rather than just the number of homes. Then work through the exclusions in order. The facts and documents matter more than the label used for the property.
- List every home and other property included in the purchase.
- Check whether the purchase is linked to another purchase.
- Ask whether group, reconstruction, acquisition or charities relief is available.
- Check whether collective-rights relief applies.
- Review lease terms and the use of any student accommodation.
- Consider whether one home is subsidiary to another.
Example
Mae buys two flats in one deal and thinks the relief for buying more than one home will reduce her LTT. However, her purchase also qualifies for charities relief. Because charities relief is available, the official source says Mae cannot claim multiple dwellings relief, even if she does not claim charities relief.
Why this can be difficult in practice
Some exclusions are easy to spot. Others are not. For example, the answer may depend on lease wording, how student accommodation is run, or whether one home is subsidiary to another.
- Calling a building a separate flat does not settle the subsidiary-home question.
- A long lease can affect whether an interest counts for the relief.
- Student halls need careful review against the official guidance.
Key takeaways
- Other available reliefs can block multiple dwellings relief.
- You cannot avoid the exclusion just by not claiming the other relief.
- Check leases, student halls and subsidiary homes carefully.
