The 2% non-resident SDLT surcharge under Schedule 9A FA 2003 catches a buyer who, on a residential UK property purchase, fails a SDLT-specific 183-day residence test. The test is not the income tax statutory residence test; it is its own simpler day-count rule, and it produces results that do not always align with how the buyer might describe their tax residency in conversation. A buyer who is UK-resident for income tax and CGT can still be caught by the 2% surcharge for SDLT, and vice versa.

This page covers the residence test itself, how the 2% stacks with the 5% HRAD surcharge and the 15% non-natural-person rate, the company residence rules (including the close-company carve-in), the joint purchaser trap, the Crown-employee exception, and the refund route available where the buyer becomes UK-resident within the post-completion window. For surcharge stacking on standard purchases see our SDLT rates pillar.

The Schedule 9A residence test, in one paragraph

Paragraph 4 of Schedule 9A FA 2003 deems an individual non-UK resident for SDLT purposes if they were present in the UK on fewer than 183 days during any continuous 365-day period that ends with the effective date of the transaction (almost always completion). A day of presence counts if the individual is in the UK at midnight at the end of that day. There are no "ties" tests, no "tax years", no automatic UK or overseas tests. Just a 183/365 count.

The test runs over a moving window. The effective date can be anywhere within the 365-day window; what matters is whether at any point during the look-back the buyer spent at least 183 days in the UK. For a buyer who returned to the UK partway through, the question is whether they accumulated 183 days by the effective date, looking back 365 days. For a buyer who left the UK partway through, the question is whether the most recent 365-day window still contains 183 UK days.

How the 2% stacks with HRAD and other surcharges

The 2% applies on top of standard residential rates and on top of other applicable surcharges. The stack runs as follows on a residential purchase:

Buyer profileStandard rate+ HRAD+ Non-resident+ 15% (NNP)Effective top-band rate
UK-resident individual, main residenceUp to 12%,,,12%
UK-resident individual, additional dwellingUp to 12%5%,,17%
Non-resident individual, additional dwellingUp to 12%5%2%,19%
UK-resident close company, dwelling > £500k, no relief,,,15%15%
Non-resident close company, dwelling > £500k, no relief,,2%15%17%
Non-resident company, additional dwelling (relief from 15% claimed)Up to 12%5%2%,19%

On a £600,000 second home bought by a non-resident company that does not claim the 15% non-natural-person rate relief, the effective top-band rate is 19%. On £600,000 the SDLT bill is therefore around £88,000, against £30,000 for a UK-resident individual replacing their main residence. The 2% is a marginal contribution to that total but a real one; on bigger purchases it compounds.

Companies: residence test plus the close-company carve-in

The company residence test in Schedule 9A is two-pronged. A company is non-UK resident for SDLT purposes if EITHER:

  • The company is not UK-resident for corporation tax purposes (the standard CT residence test, broadly central management and control plus the UK incorporation rule under section 14 CTA 2009).
  • The company is a close company within section 439 CTA 2010 AND is controlled by participators who are non-UK resident under the individual residence test in Schedule 9A.

The second prong is the close-company carve-in and catches structures that would otherwise escape. A UK-incorporated SPV with central management and control in the UK is UK-resident for CT; but if the SPV is a close company controlled by, say, a Dubai-resident individual shareholder, the SPV is treated as non-UK resident for SDLT and the 2% surcharge applies on its UK residential purchases. The control test follows the standard CT meaning: control over more than 50% of share capital, voting rights, or the right to receive most of the assets on a winding-up.

The carve-in catches a meaningful share of UK-incorporated property SPVs held by overseas individuals. Pre-2021 structures that worked on the assumption that UK incorporation alone defeated the non-resident charge no longer do. Restructuring the SPV's ownership to dilute the controlling shareholder below 50% would defeat the close-company carve-in but creates its own commercial complications.

The joint purchaser trap

Paragraph 6 of Schedule 9A treats a joint purchase as non-resident if any one of the joint purchasers fails the residence test. The 2% applies on the whole purchase, not just on the non-resident purchaser's share. Spouses and civil partners are treated as a single unit: where one spouse is non-resident the couple is non-resident for the SDLT charge, unless they are separated under a court order, formal separation agreement, or circumstances where the separation is likely to be permanent (the same separation provisions used for the additional dwellings surcharge in Schedule 4ZA).

This catches the transitional-year couple most often. A UK-national couple returning from a 3-year overseas posting completes on a UK home in the September after their return. One spouse returned in March (183 days by September: 184 days). The other spouse returned in May (183 days by September: only 134 days). The second spouse fails the SDLT test; the joint purchase is non-resident; the 2% applies. The first spouse's UK status does not save the purchase.

The remedy is timing. Delaying completion until the trailing spouse clears 183 days defuses the surcharge. Where the timing is fixed, the 2% applies but the refund route remains available once the trailing spouse hits 183 days within the 730-day window.

Crown employees and the narrow exceptions

Paragraph 9 of Schedule 9A treats certain Crown employees as UK-resident for the surcharge regardless of their physical day count. The categories include:

  • Crown servants performing duties of a Crown employment outside the UK (Foreign Office posted staff, HM forces serving overseas, GCHQ staff posted abroad).
  • Members of HM armed forces (regardless of where posted, if the conditions in paragraph 9 are satisfied).
  • Specific statutorily-listed Crown body employees (British Council, Commonwealth War Graves Commission, certain other listed organisations).

The protection extends to spouses and civil partners of Crown employees who would otherwise fail the day-count because they accompanied the employee overseas. It does not extend to private-sector UK nationals working abroad, who must meet the standard 183-day test. Treaty residents of other states do not get a free pass: UK double tax treaties cover income tax, CGT and CT but not SDLT, so a US-resident US national buying UK property pays the 2% surcharge in the usual way.

Worked example: the returning expat

To pin the mechanics down, consider Layla, a UK national who has spent the last 4 years working in Singapore on a corporate secondment. She returns to the UK on 1 March 2026 and signs a contract to buy a £750,000 family home in Surrey in July 2026 with completion scheduled for 12 October 2026. She owns no other UK property; the new home will be her main residence. Her husband Tariq returned with her on 1 March 2026.

DateEventUK day countSDLT consequence
1 March 2026Layla and Tariq return to UKDay 1 of UK presenceBoth non-resident on the SDLT test (have not yet accumulated 183 days)
30 August 2026UK day 183 reached183 days, looking back 365: comfortably satisfiedBoth UK-resident on the SDLT test from this date
12 October 2026Completion of Surrey purchase~225 days since returnBoth UK-resident at effective date. 2% surcharge does not apply. Standard residential SDLT on £750,000: £25,000 (Layla as buyer, no HRAD because she owns no other UK property and the home is her main residence).

Compare the position if completion had been brought forward to 1 July 2026: only 122 UK days, both non-resident on the SDLT test, 2% surcharge on £750,000 = £15,000 added to the bill. The refund would become available 60 days later (once Layla and Tariq cleared 183 days) and could be reclaimed within 2 years of the effective date, but in the meantime the cash sits with HMRC. Timing the completion past the 183-day threshold avoids the cashflow drag and the administrative burden of preparing and chasing the refund application. For returning expats with a clear day-count trajectory, delaying completion by even three or four weeks is often the simplest planning lever available.

The refund route on becoming UK-resident

Where the buyer was non-resident at the effective date but spends 183 or more days in the UK in any continuous 365-day period that falls within the 730-day window centred on the effective date (one year before to one year after), they qualify for a refund of the 2% surcharge.

The refund is claimed on the gov.uk online SDLT refund service. The deadline is 2 years from the effective date. The claim requires:

  • The UTRN from the original SDLT return for the purchase.
  • Evidence of UK presence over the qualifying 365-day window: passport entry stamps where available, P60 / employer correspondence showing UK employment, tenancy or utility bills showing UK address, GP registration, bank statements showing UK transactions.
  • The original surcharge amount paid (computed against the SDLT1).
  • The buyer's nominated bank account for the refund.

HMRC processes straightforward refunds in 4 to 12 weeks. Where the evidence package is patchy, or where the buyer's UK presence pattern straddles the threshold, processing runs longer and HMRC routinely opens enquiries. The buyer should keep contemporaneous records of UK days during the post-completion year.

Common errors that trigger the surcharge unnecessarily

Three errors recur in the cases we triage.

Error 1: applying the income tax SRT to the SDLT test. Solicitors and conveyancers sometimes default to the income tax residence position because that is the test they know. A buyer who is income-tax resident under the SRT's automatic UK test (e.g. has only home in the UK) but spent under 183 days in the UK during the SDLT look-back is non-resident for SDLT. The 2% applies; the buyer is surprised.

Error 2: counting partial days. Schedule 9A uses presence at midnight. A buyer who flew in on 14 March at 22:00 and out at 06:00 on 15 March was in the UK at midnight on 14 March; that counts as one day. A buyer who flew in at 02:00 on 14 March and out at 23:00 on 14 March was not in the UK at midnight; no day counts. This is mechanical but easy to misapply, and the difference matters around the 183-day threshold.

Error 3: missing the close-company carve-in. The structure is a UK Ltd, central management and control in the UK, accounts filed with Companies House, but the controlling shareholder is a non-resident individual. UK-resident for CT; non-UK resident for SDLT under the second prong. The 2% surcharge applies and is often overlooked at the structuring stage.

Trusts and the surcharge

Trusts hit Schedule 9A through specific rules. A bare trust looks through to the beneficiary, so the residence test applies to the beneficiary as the SDLT taxpayer. A trust with an interest in possession applies the test to the life tenant (the person with the right to occupy or receive income). A discretionary trust looks at the trustees as a body: the trustees are treated as non-UK resident if any one trustee is non-resident, mirroring the joint-purchaser rule.

This catches mixed-residence trustee panels often. A UK-resident family establishes a discretionary trust to hold UK residential property; one trustee is a non-resident professional adviser; the trust acquires a £500,000 buy-to-let. The trust is non-resident for SDLT, the 2% surcharge applies, and unless the non-resident trustee retires (or the trustees collectively spend 183 days in the UK in the 730-day window, which is rarely practical) the surcharge stands. The trust deed can be amended to remove the non-resident trustee before completion, but the timing must be clean.

Interaction with the 5% surcharge refund route

A non-resident buyer who would otherwise qualify for the HRAD 5% refund (replacing a previous main residence within 3 years) can claim both the HRAD refund and the 2% non-resident refund through the same gov.uk online service. The claims are filed on separate refund applications but use the same evidence package for the residence test where the buyer becomes UK-resident. Where the buyer remains non-resident at the date of the HRAD refund (i.e. the old home sells but the buyer has not yet hit 183 UK days), only the HRAD refund is available; the 2% surcharge sits as a permanent cost until the residence test is satisfied within the 730-day window.
