Derelict or uninhabitable property: telling WRA on your LTT return
Derelict or uninhabitable property and your LTT return
If the property you bought in Wales was derelict or uninhabitable, tell the Welsh Revenue Authority (WRA) in your Land Transaction Tax return. LTT is Wales’s stamp duty tax. If you did not mention this in your return, now want a refund, and need to ask WRA for one, WRA directs you to its specific derelict property refund form. Use it.
What this rule is about
Whether a building counts as residential can matter for LTT. The law asks whether people use it, or could use it, as a home. A badly damaged building may raise a real question about that suitability.
That question turns on the facts, rather than just the label in the sales details.
What the official source says
WRA says you should state in your LTT return if the property is derelict or uninhabitable. Where your return did not mention it and you now seek a refund, WRA says that you should use its specific refund form.
- Tell WRA about the property’s condition in the LTT return.
- If the return omitted this, use WRA’s derelict property refund form.
- The source does not say that every derelict property will lead to a refund.
What this means in practice
Your return contains a tax calculation based on the information you provide. Ensure that the description of the building reflects its true state when you bought it.
- Keep the completed LTT return.
- Check whether it mentioned the property’s condition.
- Use the WRA form if you missed the point and want a refund.
How to analyse it
Begin with the building’s actual condition on the relevant date. Consider whether it served as a home or could serve as one, instead of asking merely whether it needed updating.
- What parts of the building could be used safely?
- What work was needed before anyone could live there?
- When was that condition recorded?
- What documents or photographs support the answer?
Example
Amira buys a house with major damage, then files her LTT return without stating that it was uninhabitable. Later, she thinks its condition may affect the tax. WRA’s guidance says she should use the derelict property refund form. The form lets her request a refund; it does not guarantee payment.
Why this can be difficult in practice
The supplied WRA extract does not define “Derelict” and “uninhabitable”. A home needing decoration differs from one in which nobody could realistically live, but people may find the dividing line hard to show.
- Estate-agent wording may not prove the building’s condition.
- Work done after purchase may not show its earlier state.
- Good records can matter where the facts are disputed.
Key takeaways
- Tell WRA if the property was derelict or uninhabitable.
- Check what the return said about its condition.
- Use WRA’s refund form if you omitted the point and seek a refund.
