SDLT Increased Rates for Non-Resident Joint Purchasers: Rules and Exceptions Explained

SDLT non-resident surcharge for joint buyers

When more than one person buys a dwelling together, the SDLT non-resident surcharge can apply to the whole purchase if any one buyer is treated as non-UK resident under the surcharge rules. This applies even if that buyer has only a small share, and it does not matter whether the property is owned as joint tenants or tenants in common.

• Each buyer is tested separately for the non-resident surcharge rules.
• If one joint purchaser is non-UK resident, the whole transaction may be charged at the higher rate.
• The result is the same whether the buyers own as joint tenants or tenants in common.
• A very small beneficial share can still trigger the surcharge.
• Special rules may apply for some spouses or civil partners, and for Crown employees and their spouses or civil partners.
• In practice, it is important to identify all purchasers correctly and check each person’s residence status carefully.

When joint buyers trigger the SDLT non-resident surcharge

This page explains how the SDLT non-resident surcharge works where a dwelling is bought by more than one person. The key point is simple but important: if any one of the joint purchasers would be treated as non-UK resident for these rules when looked at on their own, the surcharge can apply to the whole transaction.

What this rule is about

SDLT has special higher rates for certain purchases of dwellings by non-UK residents. The source material here deals with a common practical question: what happens if there is more than one buyer?

Many residential purchases are made jointly. That may be by spouses, civil partners, family members, friends, or business partners. The buyers may hold the property as joint tenants or as tenants in common, and their beneficial shares may be equal or unequal.

The rule in this part of the SDLT manual addresses whether the non-resident surcharge is tested buyer by buyer, or by looking at the transaction as a whole. HMRC’s position, reflecting paragraph 2(1)(a) of Schedule 9A to Finance Act 2003, is that the test is applied to each purchaser individually. If the transaction would count as a non-resident transaction for any one of them, the surcharge applies.

What the official source says

The official material says that the general SDLT rules for joint purchasers are in section 103 of Finance Act 2003. For the non-resident surcharge, where there are joint purchasers, the surcharge applies if the transaction would be a non-resident transaction for any purchaser considered on their own.

The source also makes three further points:

• It does not matter whether the buyers take the property as joint tenants or tenants in common.
• It does not matter how small a particular purchaser’s interest is.
• There are special rules for spouses and civil partners of UK residents, and separate relief for Crown employees and their spouses or civil partners.

So the basic rule is deliberately broad. A very small share held by a non-resident joint buyer can still be enough to bring the whole purchase within the surcharge rules, unless a specific special rule applies.

What this means in practice

In practice, you should not assume that a joint purchase escapes the non-resident surcharge just because most of the buyers are UK resident, or because the non-resident buyer has only a minor share.

The practical effect is that a conveyancer or taxpayer needs to test each purchaser separately under the residence rules for the surcharge. If one purchaser fails that test, the transaction may be charged at the higher non-resident rates.

This can catch arrangements where:

• a UK-resident buyer adds an overseas relative as a co-owner
• spouses or partners buy together but only one meets the residence test
• one buyer is included for succession, mortgage, or family reasons but takes only a very small beneficial interest

The form of co-ownership does not change the result. Whether the buyers are joint tenants or tenants in common, the same principle applies. The size of the share also does not change the result under this rule.

How to analyse it

A sensible way to approach a joint purchase is as follows.

• Identify all purchasers for SDLT purposes. The relevant question is who is a purchaser in the chargeable transaction.
• Test each purchaser separately under the non-residence rules for the surcharge.
• Ask whether any special rule applies, particularly for certain spouses or civil partners, or for Crown employees and their spouses or civil partners.
• Do not treat a small share as irrelevant. The source makes clear that even a very small interest can still trigger the surcharge.
• Do not assume the answer changes because of the way the buyers hold the property. Joint tenancy and tenancy in common are both covered.

The key question is not “Are most of the buyers UK resident?” It is “Would this transaction be a non-resident transaction for any purchaser if that purchaser were looked at individually?” If the answer is yes, the surcharge can apply.

Example

Illustration: A and B buy a dwelling together. A is UK resident for the purposes of the surcharge rules. B is not. They decide that A will own 99% and B will own 1%, and they hold as tenants in common. On these facts, the small size of B’s share does not prevent the surcharge from applying. The transaction is tested by looking at each purchaser individually, and one of them is non-resident.

The same broad outcome would apply if A and B bought as joint tenants instead. The legal form of co-ownership does not alter this rule.

Why this can be difficult in practice

The source page states the joint purchaser rule clearly, but the difficult part is often not the joint purchaser rule itself. The difficulty is deciding whether a particular purchaser is UK resident or non-UK resident for the surcharge rules.

That residence test has its own detailed rules, and the answer may not always be obvious at the time of purchase. The source also flags that there are special rules for some spouses and civil partners, and relief for Crown employees and their spouses or civil partners. Those carve-outs mean that a simple “one non-resident buyer means surcharge always applies” statement would be too blunt.

Another practical difficulty is identifying who is truly a purchaser for SDLT purposes. In some transactions, a person may be added to title or financing arrangements for practical reasons, but their status still needs to be analysed carefully under the SDLT rules.

Key takeaways

• For a joint purchase of a dwelling, the SDLT non-resident surcharge can apply if any one purchaser is non-resident under the surcharge rules.
• It does not matter whether the buyers hold as joint tenants or tenants in common, and it does not matter how small one buyer’s share is.
• Special rules may alter the position for certain spouses or civil partners and for Crown employees and their spouses or civil partners.
