SDLT Higher Rates: Conditions for Multiple Dwellings and Additional Property Interests Explained

SDLT higher rates on buying two or more dwellings under paragraph 6

When a buyer purchases two or more dwellings in one transaction, the SDLT higher rates do not automatically apply. If only one of the purchased dwellings meets the paragraph 5 conditions, paragraph 6 must then be checked. The higher rates apply if that dwelling is not replacing the buyer’s only or main residence and, at the end of the purchase day, the buyer still owns another qualifying major interest in a different dwelling worth more than £40,000, unless that other interest is excluded because it is subject to a long lease with more than 21 years left to run.

• Paragraph 6 is relevant where a transaction includes two or more dwellings and only one purchased dwelling meets the paragraph 5 test.
• Condition A is that the relevant purchased dwelling is not a replacement for the buyer’s only or main residence.
• Condition B is that, at the end of the day of purchase, the buyer owns a major interest in another dwelling outside the purchase, worth more than £40,000.
• An interest in that other dwelling is ignored for Condition B if it is subject to a lease with more than 21 years left to run.
• The analysis must first identify which purchased dwelling satisfies paragraph 5, then check residence replacement and any other property interests the buyer holds.
• For example, buying a house and cottage can trigger higher rates if the house is not a replacement main residence and the buyer still owns another qualifying flat, but not if the only other interest is a reversion over flats on long leases.

When buying two or more dwellings, when do the SDLT higher rates apply under paragraph 6?

This page explains a specific SDLT rule for purchases involving two or more dwellings. It matters because buying several dwellings in one transaction does not automatically trigger the higher rates for additional dwellings, but it can do so if paragraph 6 of Schedule 4ZA Finance Act 2003 applies. The key question is whether at least one of the dwellings bought falls within the rule and whether the buyer already owns another relevant dwelling at the end of the purchase day.

What this rule is about

The higher rates for additional dwellings are not tested in exactly the same way where a transaction includes more than one dwelling. The legislation first looks at whether any of the purchased dwellings satisfies the conditions in paragraph 5 of Schedule 4ZA. If only one of the purchased dwellings meets those paragraph 5 conditions, the next step is to consider paragraph 6.

Paragraph 6 is designed to decide whether a multiple-dwelling purchase should still be treated as a higher rates transaction. In broad terms, it asks two things:

• Is the relevant purchased dwelling replacing the buyer’s only or main residence?
• At the end of the day of purchase, does the buyer still hold another qualifying major interest in a dwelling outside the properties being bought?

If both parts of the test are met, the transaction is a higher rates transaction.

What the official source says

The HMRC manual says that where only one of the purchased dwellings meets all three conditions in paragraph 5, paragraph 6 of Schedule 4ZA must then be considered.

Under paragraph 6, the purchase of multiple properties is a higher rates transaction if both of the following are satisfied:

• Condition A: the purchased dwelling that does meet all three paragraph 5 conditions is not a replacement for the purchaser’s only or main residence.
• Condition B: at the end of the day of purchase, the purchaser has a major interest in another dwelling, outside the dwellings being bought, and that other dwelling is worth more than £40,000 and is not subject to a lease with more than 21 years left to run.

The manual also says that if none of the purchased dwelling interests meet both conditions A and B, the higher rates do not apply. It gives as an example a purchase of a freehold reversion over a block of flats where all the flats are subject to long leases.

What this means in practice

This rule stops the analysis from ending too early just because the transaction includes several dwellings. A buyer may think that buying multiple properties changes the higher-rates position, but paragraph 6 can still bring the whole transaction into the higher rates regime.

The practical effect is that you need to identify the purchased dwelling that satisfies paragraph 5 and then test that dwelling against paragraph 6.

If that dwelling is not replacing the buyer’s only or main residence, and the buyer still owns another relevant dwelling at the end of the day, the transaction is treated as a higher rates transaction.

The reference to a dwelling “other than one of the purchased dwellings” is important. Condition B is not concerned with the dwellings being acquired in the transaction. It looks for another dwelling already owned, or otherwise held, by the buyer at the end of the purchase day.

The lease point is also important. A dwelling will not count for Condition B if the buyer’s interest in it is subject to a lease with more than 21 years left to run. That can matter where the buyer owns a reversionary interest only, rather than a straightforward freehold in possession.

How to analyse it

A sensible way to approach this rule is:

1. Confirm that the transaction involves the purchase of two or more dwellings.
2. Identify whether only one of the purchased dwellings meets all three conditions in paragraph 5.
3. Ask whether that dwelling is a replacement for the buyer’s only or main residence. If it is, Condition A is not met.
4. If it is not a replacement, check what the buyer owns at the end of the day of purchase.
5. Look for any major interest in another dwelling, outside the purchased dwellings, worth more than £40,000.
6. Check whether that other dwelling is subject to a lease with more than 21 years left to run. If it is, Condition B is not met for that dwelling.
7. If both Condition A and Condition B are met, the transaction is a higher rates transaction.

Questions worth asking include:

• Which of the purchased dwellings, if any, is the one that satisfies paragraph 5?
• Is that dwelling genuinely replacing the buyer’s only or main residence?
• What other dwellings does the buyer hold at the end of the day?
• Are those other interests major interests?
• Are they worth more than £40,000?
• Are any of them excluded because they are subject to long leases with more than 21 years remaining?

Example

Suppose an individual buys a house and a cottage in one transaction. Only the house is the purchased dwelling that meets the paragraph 5 conditions. The buyer is not replacing their only or main residence by buying that house. They also still own a separate flat, worth more than £40,000, which they let to tenants.

On those facts, the HMRC manual says Conditions A and B of paragraph 6 are met. The purchase is therefore a higher rates transaction.

By contrast, if the buyer’s only other property interest were a freehold reversion over flats that are all subject to long leases with more than 21 years left to run, the manual indicates that the higher rates would not apply in that case, because none of the purchased interests would meet both conditions A and B.

Why this can be difficult in practice

The main difficulty is that this rule sits on top of the paragraph 5 analysis. You cannot apply paragraph 6 properly unless you have first identified which purchased dwelling meets the paragraph 5 conditions.

There can also be factual uncertainty over whether a dwelling is a replacement for the buyer’s only or main residence. That question often depends on the wider residence facts and the structure of the transaction.

Another area that can cause confusion is the type of property interest the buyer holds in another dwelling at the end of the day. A buyer may own a freehold or reversionary interest, but that does not automatically mean Condition B is met. The value threshold and the long-lease exclusion must still be checked.

The manual gives a clear outcome for the examples it mentions, but real transactions can involve mixed interests, leasehold structures, and several dwellings acquired together. In those cases, careful identification of the relevant dwelling and the buyer’s other property interests is essential.

Key takeaways

• When two or more dwellings are bought, paragraph 6 can still make the transaction subject to the higher rates.
• The rule applies where the relevant purchased dwelling is not replacing the buyer’s only or main residence and the buyer still owns another qualifying dwelling at the end of the day.
• Other property interests must be checked carefully for value, whether they are major interests, and whether they are excluded because of a long lease with more than 21 years left to run.
