LTT intermediate transactions: buying between homes
If you sell your old home, buy another property, and then buy a new main home, Land Transaction Tax (LTT) may revisit the middle purchase after the replacement purchase is completed. It may not look higher-rate when bought.
What this rule is about
This rule concerns the gap between two moves. Your lived-in home is sold. No replacement home has yet been bought.
You may buy property during the gap. It need not be your main home. You will see official guidance call this an intermediate transaction.
It prevents purchase arrangements that let two homes avoid the higher LTT rates. Once the replacement-home purchase happens, reassessment is possible.
What the official source says
Official Welsh guidance says the rule can apply where a buyer sells a previous only or main home, makes a middle purchase during the interim period, and then replaces that main home in another purchase. It must occur in that period.
- The interim period starts on the effective date on which the sale of the old main home takes effect for LTT purposes under the rules. That date controls.
- It ends on the effective date of the purchase that replaces that home.
- The guidance describes the replacement purchase as taking place within three years after the old-home sale, measured from the effective date of that sale. This is the usual period.
- The middle property is not intended, on its effective date or at any earlier point in the interim period, to be your main home. That intention matters.
- A middle purchase of one home has its own statutory test.
- A purchase of several homes has a separate test, including a rule about qualifying homes.
- The rule can apply in a joint purchase because of the position of any one buyer, even where the other buyers are differently placed. Each position matters.
Qualifying middle purchases face higher residential rates. Treatment starts when the interim period ends. In simple terms, a later purchase of your new main home can change the LTT position on the earlier middle purchase.
What this means in practice
Do not assume the LTT result is fixed forever on the day you buy the middle property. A later purchase may require another tax calculation and a further return.
This differs from the normal rule for buying a replacement home. It deals with the unusual sequence in which you sell, buy another property, and then buy the home in which you will live as your main home. That sequence matters.
- Keep the dates for all three transactions together.
- Check why the middle property was bought and how you intended to use it.
- Check whether the later purchase really meets the replacement-main-home conditions.
- Do not ignore a middle purchase because it was not your main home.
- Where the rule applies, send a further LTT return to the Welsh Revenue Authority.
- The return must be made within 30 days after the interim period ends.
- The return must include your calculation of the tax due.
How to analyse it
Begin with the order of events. What you call the purchases matters less. Was it between your home moves?
- Identify the effective date of the old-home sale.
- Identify the effective date of every purchase made after that sale.
- Decide which purchase, if any, was the replacement for your main home.
- Check whether the middle purchase falls within the period between those two events.
- For a Welsh former home, test the replacement purchase under the Welsh LTT rules.
- If your former home was in England, Northern Ireland or Scotland, use the relevant replacement-home test named in the legislation that applies to that jurisdiction. Use it.
- Check whether the middle purchase was of one home or more than one home.
- Work out whether a further LTT return is due when the interim period ends.
Example
Amir sells the house where he lives on 1 May. He buys a flat as an investment in June. In February the next year, he buys a house to be his new main home.
His flat purchase came after the sale and before the new-home purchase. If the statutory conditions are met, it is an intermediate transaction. From February, LTT can treat the flat purchase as a higher-rate purchase. Amir must make the further return within 30 days after that period ends.
Why this can be difficult in practice
Usually, the timeline is not the difficult part. Showing what each property meant in your real life at the time is. Later moving into a home does not simply make it a main home.
The three dates may seem to decide the answer. They do not. Both the replacement-home conditions and the nature of the middle purchase matter too.
- People may confuse a temporary property with a replacement main home.
- Completion dates may not always be the effective dates that LTT uses.
- Joint buyers need to consider each buyer’s position.
- Buying several homes at once brings a different statutory test.
- The guidance gives the usual three-year period, but current legislation has limited extensions in particular cases.
Key takeaways
- LTT can reassess a property bought between two home moves.
- The later purchase of your new main home can trigger the result.
- When the rule applies, a further LTT return is due within 30 days.

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 was your only or main home is fact-sensitive.
- The date that counts for LTT is the effective date, which may not always be the completion date.
- The precise result for a purchase of more than one home depends on the statutory qualifying-home test.
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 and effective dates for the old-home sale, middle purchase and replacement-home purchase
- Evidence showing which home was your only or main home
- Details of the purpose and use intended for the middle property
- Copies of the relevant LTT returns and purchase documents
