SDLT Non-Resident Surcharge: Company Residency Criteria and Special Rules Explained

When a company is treated as non-UK resident for the SDLT surcharge

For the SDLT non-resident surcharge, a company is not judged only by its normal UK tax residence. On the effective date of the transaction, a company is treated as non-UK resident if it is not UK resident for corporation tax, or if it is UK resident but is a close company, under non-UK control for that transaction, and not an excluded company.

• A UK-resident company can still be treated as non-UK resident for SDLT surcharge purposes.
• The test is applied on the effective date of the land transaction.
• If the company is not UK resident for corporation tax, it is treated as non-resident for this surcharge.
• If the company is UK resident, you must check whether it is a close company, whether there is non-UK control in relation to the transaction, and whether any exclusion applies.
• Special rules may apply to some structures, including co-ownership authorised contractual schemes and certain alternative property finance arrangements.
• Terms such as “close company”, “non-UK control test” and “excluded company” are defined in tax law and should be checked in the legislation or official guidance.

When a company is treated as non-UK resident for the SDLT non-resident surcharge

This page explains when a company counts as “non-resident” for the purposes of the SDLT surcharge on certain residential land transactions. This is important because a company can be treated as non-resident even if it is UK resident for corporation tax. The surcharge rules therefore go beyond ordinary tax residence and look at who controls the company in some cases.

What this rule is about

The source material deals with the special meaning of “non-resident” for a company buying land where the SDLT non-resident surcharge may apply. The question is not simply whether the company is incorporated in the UK or generally thought of as UK-based. The legislation uses a specific test tied to the effective date of the transaction.

For companies, there are two broad routes by which they can be treated as non-resident in relation to a chargeable transaction:

• the company is not UK resident for corporation tax purposes; or
• the company is UK resident for corporation tax purposes, but is closely held, under non-UK control for the transaction, and is not an excluded company.

This matters because a UK-resident company is not automatically outside the surcharge rules. In some cases, a UK-resident close company can still be treated as non-resident for this purpose.

What the official source says

According to paragraph 7 of Schedule 9A to Finance Act 2003, a company is non-resident in relation to a chargeable transaction if, on the effective date of the transaction, either of two conditions is met.

The first condition is straightforward: the company is not UK resident for the purposes of the Corporation Tax Acts.

The second condition applies where the company is UK resident for corporation tax purposes, but all three of the following are true:

• it is a close company;
• it meets the non-UK control test in relation to the transaction; and
• it is not an excluded company.

The manual also notes that special rules apply in some cases, including co-ownership authorised contractual schemes and certain alternative property finance arrangements involving financial institutions.

What this means in practice

The practical point is that company residence for the surcharge is not limited to the usual corporation tax residence test. A non-UK resident company will generally fall within the company non-resident rule immediately. But even a UK-resident company may still be treated as non-resident if it is closely controlled from outside the UK and no exclusion applies.

This is an anti-avoidance shaped rule. It stops the surcharge being avoided simply by interposing a UK-resident company where the real control sits outside the UK.

The timing is also important. The test is applied on the effective date of the chargeable transaction. So the relevant questions about residence, close company status, control, and exclusions must be answered at that date.

In practice, anyone analysing the SDLT position for a company purchaser should not stop at asking, “Is the company UK resident?” If the company is UK resident, the next questions are whether it is a close company, whether non-UK control exists for this transaction, and whether it falls within an excluded category.

How to analyse it

A sensible way to approach the issue is:

• First, identify the effective date of the chargeable transaction. That is the date on which the test is applied.
• Next, ask whether the company is UK resident for the purposes of the Corporation Tax Acts at that date.
• If it is not UK resident, the company is treated as non-resident for the surcharge.
• If it is UK resident, ask whether it is a close company.
• If it is not a close company, this particular rule in paragraph 7(3) does not make it non-resident.
• If it is a close company, ask whether it meets the non-UK control test in relation to the transaction.
• If it does, ask whether it is an excluded company. If it is excluded, the rule does not treat it as non-resident under this route.
• If it is UK resident, close, non-UK controlled for the transaction, and not excluded, it is treated as non-resident for surcharge purposes.

The source material does not set out the detailed meaning of “close company”, “non-UK control test”, or “excluded company”, so those terms need to be checked in the relevant legislation or related guidance rather than guessed from ordinary language.

Example

Illustration: a company buying a dwelling in England is UK resident for corporation tax purposes on the effective date. If that company is closely held, is under non-UK control for the transaction, and is not an excluded company, it can still be treated as non-resident for the SDLT surcharge. So a UK-resident company is not automatically outside the surcharge.

By contrast, if a company is UK resident but is not a close company, this particular rule does not treat it as non-resident merely because of overseas ownership or influence.

Why this can be difficult in practice

The source rule is short, but applying it can be technical.

First, the legislation uses defined tax concepts rather than ordinary language. Whether a company is “UK resident” for corporation tax, whether it is a “close company”, and whether it meets the “non-UK control test” are all legal questions with their own rules.

Second, the control test is stated to apply “in relation to the transaction”. That suggests a transaction-specific analysis may be needed, rather than only a broad look at the company’s usual ownership structure.

Third, the excluded company carve-out means the analysis is incomplete unless exclusions have been checked. A company may appear to fall within the rule until an exclusion is considered.

Finally, special rules apply for some structures, including co-ownership authorised contractual schemes and certain alternative property finance cases. Those situations should not be analysed solely by using the basic company rule.

Key takeaways

• A company can be treated as non-resident for the SDLT surcharge even if it is UK resident for corporation tax.
• The key date is the effective date of the transaction.
• For a UK-resident company, close company status, non-UK control, and any exclusion must all be checked carefully.
