LTT relief when a property trader saves a broken home-sale chain
LTT relief when a property trader saves a broken home-sale chain
If a buyer pulls out and puts your next home at risk, a property trader may step in to buy your old home. Land Transaction Tax, the Welsh form of stamp duty, may not be due on that purchase. Yet the relief is narrow and depends on the real facts.
What this rule is about
Property chains can fail at the worst moment. After agreeing both deals, your buyer withdraws.
This relief targets a business that buys the old home so the person can still complete on their next home. It is not a general tax break for every company that buys a house.
Technical guidance from the Welsh Revenue Authority explains this rule. Legislation decides whether the relief applies.
What the official source says
Where an individual’s planned sale fails, relief can apply if a property trader buys that old home as part of a business that includes buying homes in those chain-break situations. That business link is essential.
- To qualify, the person must have arranged to sell their old home and buy a second home.
- For relief to apply, the planned sale of the old home must have failed.
- Crucially, the trader’s purchase must help the person’s second-home purchase go ahead.
- At some point in the previous two years, the person must have lived in the old home as their only or main home.
- For the second home, the person must intend to live there as their only or main home.
- Refurbishment plans must not take the trader above the allowed refurbishment limit.
- The trader must not plan to let the old home, except back to that person for up to six months.
- The trader must not allow its principals, employees, or connected people to live there.
- The land bought must stay within the permitted garden and grounds area for full relief.
A property trader is not simply any person who buys property. Under the law, it must be a company, limited liability partnership, or certain corporate partnership that runs a business buying and selling homes. A connected company can also be treated as part of that trader for this rule.
What this means in practice
Ask why the trader bought. What matters is whether, rather than merely seeing an investment opportunity after an earlier sale failed, the trader bought in order to get the person’s next home purchase over the line. That purpose must be real.
That link matters. A trader buying later because the home looked like a good investment would not meet this condition merely because an earlier sale had failed.
- Keep the paperwork for the failed sale and the planned onward purchase.
- Record why the trader’s purchase was needed for the next purchase to continue.
- Check that the seller lived in the old home within the required two-year period.
- Check the trader’s plans before claiming relief, not only what happens later.
- Claim the relief in the first LTT return or an amendment to it.
The amount can never exceed £20,000. The limit is the greater of £10,000 and 5% of the amount paid. Cleaning and work needed only to meet minimum safety standards do not count as refurbishment for this limit.
How to analyse it
Work through the facts in order. A signed sale agreement alone may not tell the whole story, especially if there were changed terms or a replacement buyer.
- Was there a real arrangement to sell the old home?
- Was there a real arrangement to buy a second home?
- What exactly caused the old-home sale to fail?
- Did the trader buy so that the second purchase could proceed?
- Does the trader run the type of home-buying business the law requires?
- Did the seller use the old home as their main home within two years?
- Will the seller use the second home as their main home?
- What work, letting and occupation does the trader plan after purchase?
- Does the land include more than the permitted garden and grounds?
If the land is too extensive, that does not always end the claim. The law can give partial relief instead. Partial relief uses a market-value subtraction. It treats the taxable amount as the old home’s market value less the market value of the permitted area.
Example
Rhiannon has agreed to sell her home for £400,000 and to buy another home. Her buyer withdraws shortly before completion. A qualifying property trader buys Rhiannon’s old home so she can complete on the next purchase. Rhiannon lived there within two years. She plans to live in the new one.
For the purchase, the trader pays £400,000. Its permitted refurbishment amount is £20,000: 5% would be £20,000, which is also the statutory maximum. If all the other conditions are met, full relief may be available. If the trader later spends £25,000 on value-improving work, the relief is withdrawn.
Why this can be difficult in practice
This is the part people get wrong: a broken chain is necessary, but it is not enough on its own. Both the reason for the trader’s purchase and the trader’s later actions matter.
- A delayed purchase may not show that the trader enabled the next purchase to proceed.
- Land such as paddocks, fields or large gardens may raise difficult permitted-area questions.
- Work described as repairs may still be refurbishment if it is meant to increase value.
- A letting or occupation arrangement can withdraw relief even after a valid original claim.
When relief is withdrawn, the tax becomes the amount that would have been due without it. The buyer must send the WRA a further return, including a self-assessment, within 30 days beginning the day after the withdrawal event.
Key takeaways
- This relief is for a qualifying property trader that saves a failed sale chain.
- The old home must recently have been the seller’s main home.
- Later spending, letting or staff occupation can remove the relief.

Official guidance
The pages below are the Welsh Revenue Authority’s guidance. Guidance is not law. It sets out how the Welsh Revenue Authority reads the legislation, and it is not binding on you, on a tribunal or on a court. Where guidance and the legislation differ, the legislation wins. the Welsh Revenue Authority can also change or withdraw guidance, and it may not cover your facts.
Where this is not settled
- Whether arrangements genuinely failed, and whether the trader’s purchase enabled the next purchase to proceed, depend on the evidence and facts.
- Whether land above 0.5 hectares is needed for reasonable enjoyment as a home depends on its size and character.
- The statutory material supplied does not record a general currency date for Schedule 14, so its current status should be checked before relying on it for a live transaction.
Evidence you would need
This kind of case is decided on the facts of the individual property. These are the records that usually settle it, and the ones an adviser would ask you for.
- Documents showing the original planned sale and purchase arrangements.
- Evidence that the original sale failed.
- Evidence that the trader’s purchase allowed the next home purchase to proceed.
- Proof that the old home was the person’s only or main home during the two-year period.
- Evidence of the person’s intended occupation of the second home.
- The trader’s business records, refurbishment budget, tenancy records and occupation records.
- A plan and valuation evidence where the land may exceed the permitted area.
