Guide on SDLT Returns for Non-Residents Becoming UK Residents After Transaction

SDLT non-resident surcharge after a buyer later becomes UK resident

If an individual buyer is not yet UK resident under the special SDLT residence test when the SDLT return is filed, the return must be completed as if they will stay non-resident for the rest of the relevant period. This can mean paying the 2% non-resident surcharge up front, then amending the return later to claim a refund if the buyer subsequently meets the test. For joint buyers, all purchasers must qualify before a refund can be claimed.

• The SDLT residence test looks at a period that includes time after completion, so a buyer may become UK resident for surcharge purposes only later.
• Because the SDLT return is usually due within 14 days of completion, it must be filed based on the position known then, using the legal assumption that the buyer remains non-resident if the test is not yet met.
• If the other surcharge rules apply, the 2% non-resident surcharge must be paid at filing rather than waiting to see what happens later.
• If the buyer later spends enough days in the UK to satisfy the Schedule 9A test, the SDLT return can be amended and the surcharge reclaimed.
• The amendment must be made within two years starting the day after the transaction’s effective date.
• Where there is more than one purchaser, a refund is only available if every purchaser is an individual who becomes UK resident in relation to the transaction.

SDLT non-resident surcharge: what happens if an individual becomes UK resident after filing the return

This page explains a practical timing problem in the SDLT non-resident surcharge rules for England and Northern Ireland. An individual can count as UK resident for surcharge purposes even if they only reach the required UK day-count after the purchase completes. But the SDLT return usually has to be filed within 14 days of completion, before that later residence position is known. The legislation deals with this by requiring the return to be filed on a temporary assumption, with a later amendment and refund if the buyer ultimately becomes UK resident.

What this rule is about

For the SDLT non-resident surcharge, an individual’s residence is tested by looking at a “relevant period” that can extend beyond the effective date of the transaction. Broadly, the rule looks at a continuous period made up of 364 days before the effective date and 365 days after it. That means a person may not be UK resident for these purposes at the date of completion, but may become UK resident in relation to the transaction later if they spend enough days in the UK within the permitted period.

This creates an obvious filing issue. SDLT returns are normally due within 14 days of the effective date. At that point, the buyer may not yet have spent enough days in the UK to satisfy the residence test. The legislation therefore tells you how to complete the return in the meantime.

What the official source says

HMRC’s manual explains paragraphs 18 and 19 of Schedule 9A to Finance Act 2003.

Paragraph 18 says that if, when the SDLT return is filed, an individual has not yet established UK residence under the paragraph 4 residence test, the return must be completed on the assumption that the individual is non-resident for the rest of the relevant period.

In practical terms, that means:

• you do not wait to see whether the individual later becomes UK resident;
• you file the return on the basis of the facts known at the filing date, using the statutory assumption that the individual remains non-resident for the remainder of the relevant period; and
• if the other surcharge conditions are met, the 2% non-resident surcharge is paid at that stage.

Paragraph 19 then provides the correction mechanism. If the individual later becomes UK resident in relation to the transaction under paragraph 4, the purchaser can amend the SDLT return and claim a refund of the surcharge. The amendment must be made within two years beginning with the day after the effective date of the transaction.

The manual also highlights an important point for joint purchases. If there is more than one purchaser, all purchasers must be individuals who become UK resident in relation to the transaction before a refund can be claimed. They do not all need to use the same 365-day period, but each of them must satisfy the paragraph 4 test.

What this means in practice

The return may need to be filed on a “pay now, reclaim later” basis.

If an individual buyer has not yet reached the required UK presence by the time the SDLT return is submitted, the conveyancer or taxpayer should not try to anticipate future residence by ignoring the surcharge. The legislation requires the return to be completed as if the buyer will remain non-resident for the rest of the relevant period.

So, where the transaction otherwise falls within the non-resident surcharge rules, the surcharge is included in the SDLT calculation and paid with the return.

If the buyer later does spend enough days in the UK to become UK resident in relation to that transaction, the earlier filing position can be corrected by amending the return. The result is that the transaction is treated as not liable to the surcharge, and the surcharge can be refunded.

This matters because the residence test for this surcharge is not simply a snapshot at completion. It can change after completion, but the return still has to be filed quickly. Paragraphs 18 and 19 are there to bridge that gap.

How to analyse it

A sensible way to approach this issue is to ask the following questions.

• Is the transaction one to which the non-resident surcharge rules could apply at all?
• Who are the purchasers, and are they individuals?
• At the date the SDLT return is being delivered, has each relevant individual already satisfied the paragraph 4 residence test?
• If not, does paragraph 18 require the return to be completed on the assumption that the individual remains non-resident for the rest of the relevant period?
• If the surcharge is paid on that basis, is there a realistic possibility that the individual will later satisfy the paragraph 4 test?
• If there is more than one purchaser, have all of them become UK resident in relation to the transaction, not just one of them?
• Has the amendment been made within the two-year time limit starting the day after the effective date?

It is also important to separate two stages of the analysis:

• the filing stage, where the statutory assumption may force a non-resident treatment; and
• the later correction stage, where actual residence over the full relevant period may show that the surcharge was not ultimately due.

The official source also notes that an amendment under paragraph 19 does not need to be accompanied by the contract or transfer documents referred to in paragraph 6(2A) of Schedule 10 to Finance Act 2003.

Example

Illustration: An individual living outside the UK buys a residential property in England. Completion takes place on 1 June, and the SDLT return is filed on 2 June. By 2 June, the buyer has spent 100 days in the UK during the relevant period. That is not enough at the filing date to establish UK residence under the paragraph 4 rule.

The return must therefore be filed on the assumption that the buyer will remain non-resident for the rest of the relevant period. If the other conditions for the surcharge are met, the 2% surcharge is paid.

Suppose the buyer then spends enough further days in the UK so that, looking at the relevant period as a whole, they do become UK resident in relation to the transaction. The buyer can then amend the SDLT return and claim back the surcharge, provided the amendment is made within the statutory two-year period.

If there had been two individual buyers, a refund would only be available once both of them had become UK resident in relation to the transaction.

Why this can be difficult in practice

The main difficulty is timing. The legal test for residence can depend on events after completion, but the tax return is due very soon after completion. That means the filing position and the final tax position may differ.

Joint purchases make this more complicated. A common misunderstanding is to assume that if one buyer later becomes UK resident, part of the surcharge can be reclaimed. That is not what the HMRC material says. For a refund under paragraph 19, all purchasers must be individuals who are UK resident in relation to the transaction.

Another practical issue is record-keeping. The ability to reclaim depends on being able to show that the paragraph 4 residence test was ultimately met within the relevant period. The source material does not expand on evidential standards here, but in practice the day-count must be supportable.

There is also room for confusion between general UK tax residence and the special residence rule used for this surcharge. The source material is dealing with the paragraph 4 test in Schedule 9A, which is a specific statutory test for this SDLT purpose.

Key takeaways

• If an individual has not yet become UK resident under the Schedule 9A residence test when the SDLT return is filed, the return must be completed on the assumption that they remain non-resident.
• That can mean paying the 2% non-resident surcharge first, even if the buyer later becomes UK resident in relation to the transaction.
• If the buyer later satisfies the residence test, the return can be amended and the surcharge reclaimed within two years from the day after the effective date, but for joint purchases all buyers must qualify.
