When higher Land Transaction Tax rates do not apply
When higher LTT rates may not apply
The Welsh Revenue Authority lists several situations where higher residential LTT rates will not usually apply.
- You have sold your old main home before, or on, the day you buy the new one.
- The purchase is below £40,000, mixed-use, or moveable property.
- A freehold reversion subject to a qualifying long lease can also be outside the test.

When higher Land Transaction Tax rates do not apply
Higher LTT rates will not usually apply if you sold your old main home before purchasing your new one, or if both transactions completed on the same day.
Land Transaction Tax replaced Stamp Duty Land Tax in Wales in 2018. On your purchase, this can make a substantial difference to the tax due.
What this rule is about
The higher rates target certain purchases in which the buyer will own more than one home. They do not, however, apply to every property purchase. Some purchases are outside the test from the outset.
If your conveyancer says that higher rates apply, consider the position carefully, especially if you think they should not, because your property and circumstances at the time of purchase decide the result. Details matter.
What the official source says
According to the Welsh Revenue Authority, you will not usually pay higher rates in the following situations. These points apply only to the higher rates. Ordinary LTT may still be due.
- You will use the new property as your main home.
- You sold the last main home you owned before buying it, or on the same day.
- The property is worth less than £40,000.
- The purchase includes both residential and non-residential space.
- The property is moveable, such as a caravan, houseboat or mobile home.
- You buy a freehold interest subject to a long lease held by an unconnected person.
- For that lease exception, more than 21 years must remain on the lease.
What this means in practice
For the official mixed-use example, consider a shop with a flat above it. Because the purchase includes non-residential space, it is not treated as a higher-rates residential purchase. That does not mean it is tax-free.
Whether the sale completes before the new purchase or both transactions complete on the same day determines this, because the completion order matters for the higher-rates position. Timing matters.
- Check the completion date, not just the date you accepted an offer.
- Keep documents showing when your old home was sold.
- Check whether the new property will really be your main home.
- Read the contract and title plan if there is a shop, office or other business area.
- For a long lease, check both its remaining term and who holds it.
How to analyse it
First, ask whether you are buying an ordinary residential property or something different for LTT purposes because of its character or use. Estate-agent labels alone are insufficient.
- Work out what land and buildings are included in the purchase.
- Check whether any part has non-residential use.
- Confirm the total amount you are paying is below £40,000, if that is relevant.
- Ask whether the property is genuinely moveable rather than land you are buying.
- Compare the completion dates for your old and new main homes.
- If there is a lease, find its expiry date and identify the leaseholder.
Example
Amira sells the home she lives in on 10 June and completes the purchase of her new home that same day. She plans to live there.
For Amira, the official source presents this as a main-home situation in which she will not usually pay the higher rates. That is the stated main-home situation.
Another example shows that a residential purchase for £39,999 falls below the £40,000 amount in the basic higher-rates test. It therefore does not meet that test. The purchase price is below the threshold.
Why this can be difficult in practice
Labels may be misleading. A description such as a houseboat, a holiday unit or mixed-use property does not determine the answer. The actual facts and legal documents matter.
The main-home rule has fuller conditions in the legislation. The official page sets out the common, simple case: your old main home has already been sold, or is sold on that day.
- An agreed sale is not the same as a completed sale.
- A small business element may affect how the whole purchase is taxed.
- A caravan fixed permanently to land may need closer examination.
- A lease held by someone connected with you does not meet the stated lease exception.
Key takeaways
- Selling your old main home first will usually prevent higher rates.
- Mixed-use and moveable property can fall outside higher rates.
- Check completion dates, property use and lease details carefully.

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 a property is genuinely mixed-use can depend on what is being bought and how each part is used.
- Whether a caravan, houseboat or mobile home is moveable may depend on the facts and the legal interest being transferred.
- The available skill files did not include the requested currency notice, so the current status of these rules should be checked before publication.
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.
- Completion dates for the old and new main homes
- Evidence that the new property will be your main home
- The agreed price and any other amount paid
- Plans, title documents and details of any business use
- Lease details and whether the tenant is connected with you
