Guide on SDLT Surcharge for Non-Resident Property Transactions in the UK

When an individual is treated as UK resident for the SDLT non-resident surcharge

For the 2% SDLT non-resident surcharge on some residential purchases in England and Northern Ireland, an individual uses a special transaction-based residence test, not the usual UK statutory residence test. The key question is whether the buyer is in the UK at the end of at least 183 days within any continuous 365-day period that falls within a set window around the purchase date. Because the SDLT return is due quickly, a buyer may need to pay the surcharge first and reclaim it later if they later meet the test.

• The relevant window runs from 364 days before the transaction’s effective date to 365 days after it.
• A day counts only if the individual is in the UK at the end of that day, and days anywhere in the UK count.
• It is not enough to total 183 days across the wider window; the days must fall within one continuous 365-day period.
• If the buyer has not met the test by the SDLT filing deadline, the return is normally filed on the basis that they are non-UK resident for this purpose.
• If the buyer later satisfies the test, they may be able to amend the return and claim a refund of the 2% surcharge, if the transaction then ceases to be non-resident.
• For joint buyers, each purchaser must usually meet the residence requirement separately, unless a special rule applies.

SDLT non-resident surcharge: when an individual is treated as UK resident for a property purchase

This page explains the special residence test used for the 2% SDLT non-resident surcharge on certain residential purchases in England and Northern Ireland. The key point is that this is not the normal UK statutory residence test used for income tax or capital gains tax. For this surcharge, residence is worked out using a day-counting rule tied to the transaction itself.

What this rule is about

Schedule 9A Finance Act 2003 imposes a higher SDLT rate for certain “non-resident transactions”. One of the questions is whether an individual purchaser is UK resident in relation to that transaction.

For individuals, the basic rule looks at physical presence in the UK for at least 183 days in a continuous 365-day period. That 365-day period must fall within a wider window linked to the effective date of the transaction.

This matters because:

• if the purchaser is treated as non-UK resident for these purposes, the 2% surcharge may apply;
• the SDLT return usually has to be filed before it is possible to know whether a purchaser will later meet the 183-day test; and
• a refund may be available later if the purchaser does go on to satisfy the rule.

This page deals only with the basic rule where all purchasers are individuals. Different rules apply in other cases, including some joint purchase situations and some spouse or civil partner cases.

What the official source says

Under paragraph 4 of Schedule 9A FA 2003, an individual is UK resident in relation to a chargeable transaction if they are present in the UK on at least 183 days during any continuous 365-day period that falls within the “relevant period”.

The relevant period:

• starts 364 days before the effective date of the transaction; and
• ends 365 days after the effective date.

So the legislation gives a wide window around the transaction date, but the actual qualifying test is still 183 days in one continuous 365-day period within that window.

A day counts as a day in the UK if the individual is in the UK at the end of that day.

The source also makes four practical points:

• this SDLT residence test is different from the statutory residence test used for other taxes;
• days spent anywhere in the UK count, not just days in England or Northern Ireland;
• because the SDLT return is due within 14 days of the effective date, the return may have to be filed on the basis that the purchaser is non-UK resident even if they will later satisfy the 183-day rule; and
• if the purchaser later does satisfy the rule, the return can be amended and a refund of the 2% surcharge claimed, provided the transaction is then not a non-resident transaction.

What this means in practice

The practical effect is that residence for this surcharge is transaction-specific. It is not enough to ask, “Is this person UK resident generally?” Instead, you ask whether they have 183 UK days in any continuous 365-day period within the statutory window around the purchase.

That can produce results that feel unusual:

• a person living abroad may still be UK resident for this SDLT test if they have enough UK days;
• a person who will spend enough time in the UK after completion may initially have to pay the surcharge, then reclaim it later; and
• a person may spend 183 days or more in the overall relevant period but still fail the test if those days are not contained within one continuous 365-day period.

The filing position is especially important. At the time the SDLT return is submitted, if the purchaser has not yet reached 183 UK days in a qualifying 365-day period, the return must be completed on the assumption that they are non-UK resident. If the other conditions for a non-resident transaction are met, the surcharge must be paid at that stage.

Later, if the purchaser does satisfy the residence requirement, they may amend the return and seek a refund. But that only works if the transaction ultimately ceases to be a non-resident transaction under the statutory conditions.

For joint purchasers, the position is stricter. The transaction only stops being a non-resident transaction when every purchaser meets the relevant residence requirement, unless a special rule changes the analysis. One purchaser qualifying is not enough.

How to analyse it

A sensible way to work through the rule is:

1. Identify the effective date of the transaction.
2. Work out the relevant period: from 364 days before that date to 365 days after it.
3. Ask whether the purchaser has at least 183 days in the UK in any continuous 365-day period within that relevant period.
4. Count a day only if the person is in the UK at the end of that day.
5. Count days spent anywhere in the UK, not only in England or Northern Ireland.
6. Check the filing date position. If, when the SDLT return is due, the purchaser has not yet met the test, the return is filed on the basis that they are non-UK resident.
7. If there is more than one purchaser, repeat the analysis for each one separately. Their qualifying 365-day periods do not have to be the same, but each purchaser must satisfy the rule.

Questions worth asking include:

• Are all purchasers individuals, so that this basic rule applies?
• Is there a spouse or civil partner rule that changes the result?
• Have the UK days been counted by reference to where the person was at the end of each day?
• Do the days actually fall within one continuous 365-day period, rather than being spread too widely?
• At the filing date, is there enough evidence to support treatment as UK resident for this transaction?

Example

Illustration: A buyer completes on a residential purchase in England on 1 June 2025. By the filing deadline, they have not yet spent 183 days in the UK in a qualifying 365-day period, so the SDLT return is filed on the basis that the 2% non-resident surcharge is due.

After completion, the buyer continues living in the UK and by 1 June 2026 they have spent 200 days in the UK during the continuous 365-day period from 2 June 2025 to 1 June 2026. Under the statutory test, they are UK resident in relation to the transaction. The return can then be amended and a refund of the surcharge claimed, assuming the other conditions for a non-resident transaction are no longer met.

By contrast, if a buyer has enough UK days only when adding together separate periods that do not fit inside one continuous 365-day period, they do not satisfy the test, even if their total days in the wider relevant period exceed 183.

Why this can be difficult in practice

The main difficulty is timing. SDLT has to be reported quickly, but this residence test can depend on days spent in the UK after completion. That means the legally correct filing position may be “pay now, reclaim later”.

Another difficulty is that people often confuse this rule with the statutory residence test for other taxes. The source is clear that this is a different test. A person can be UK resident under one regime and not the other.

Joint purchases can also be easy to misread. The fact that one or two buyers satisfy the 183-day rule does not by itself remove the surcharge. Under the basic approach described by the source, all purchasers must meet the requirement before the transaction stops being a non-resident transaction, subject to any special rules that apply.

Finally, counting days can be deceptively technical. The legislation looks at whether the person is in the UK at the end of the day. It also requires the 183 days to fall within a continuous 365-day period. A rough total over two years is not enough.

Key takeaways

• For the SDLT non-resident surcharge, individuals use a special 183-days-in-365 test, not the normal statutory residence test.
• The SDLT return may need to be filed, and the surcharge paid, before a purchaser can qualify as UK resident under this rule.
• In joint purchases, each purchaser must be tested separately, and the surcharge may remain unless all relevant purchasers satisfy the residence requirement.
