The Labour Party 2024 General Election manifesto included a commitment to increase the non-resident SDLT surcharge under FA 2003 Schedule 9A from the current 2% rate to 3% as a flagship anti-overseas-investor housing-affordability measure. The commitment was one element of a wider set of housing-policy proposals, alongside Build-to-Rent regulation, planning reform, and the Renters' Reform legislation. The non-resident SDLT surcharge was the specific tax measure in the housing-affordability set. This page sets out the current statutory position on the Schedule 9A surcharge, the trajectory of the manifesto commitment through the Autumn Budget 2024 and Spring Statement 2025, the stacking interaction with the 5% additional dwellings surcharge under Schedule 4ZA, worked SDLT examples at both the current 2% rate and the hypothetical 3% rate across the typical £500,000 to £2 million non-resident-purchase band, and practical guidance for non-resident buyers facing rate-uncertainty in transactions in flight.

The current statutory position as at 26 May 2026

The non-resident SDLT surcharge under FA 2003 Schedule 9A remains at 2%, the rate originally introduced by FA 2021 s.86 and Schedule 16 with effect from 1 April 2021. The 2% rate is added to each band of the rates that would otherwise apply, with the computation set out at FA 2003 s.55C. The surcharge applies to residential transactions by buyers who fail the SDLT-specific 183-day residence test under Schedule 9A paragraph 4. Verbatim Schedule 9A text at legislation.gov.uk/ukpga/2003/14/schedule/9A (verified 2026-05-26).

The proposed 1-percentage-point increase from 2% to 3% has not been legislated as at the date of this page. The Autumn Budget 2024 (delivered by the Labour Chancellor in October 2024 after the General Election) and the Spring Statement 2025 did not include the legislative implementation of the manifesto commitment on the non-resident SDLT surcharge. The current Finance Act in force is FA 2025 c.8, which includes the 5% additional dwellings surcharge rate under s.51 (in force from 31 October 2024) but does not change the Schedule 9A rate. Readers should check the current statutory rate against gov.uk and against any Finance Bill 2025-26 or subsequent Finance Act before relying on this page for a transaction; this page is a snapshot of the policy state on 26 May 2026.

The Labour 2024 manifesto commitment

The 2024 Labour manifesto committed to increasing the non-resident SDLT surcharge by 1 percentage point, from 2% to 3%, as a measure to reduce the competitive disadvantage of UK-resident buyers competing with cash-rich overseas investors in higher-value UK housing markets. The proposed increase was positioned as a flagship measure within a broader housing-affordability package. The stated rationale was housing affordability for UK residents: the premise that overseas-cash buyers compete with UK-resident buyers in higher-value markets (particularly London prime), pushing prices upward and reducing affordability for UK households. The surcharge increase was intended to dampen overseas-cash demand at the margin.

The Labour manifesto did not specify a commencement date for the increase. The commitment was at the level of a policy direction, not a fixed legislative timetable. In the UK SDLT system, surcharge rate changes are typically legislated through a Finance Act with a commencement date set in the Act itself.

Critique and the policy debate

The policy debate on the non-resident SDLT surcharge is conducted at the level of effectiveness and design. Three lines of critique recur in market commentary:

  • Market-share effect: non-resident buyers are a small share of the wider UK housing market by volume; the surcharge has limited supply-side effect on UK-resident affordability because most UK transactions do not involve non-resident buyers in the first place.
  • Prime-market sensitivity: the surcharge is most binding in prime central London and similar prime regional markets, where the overseas-buyer share is highest. These markets are also least sensitive to a 1 or 2 percentage-point rate change because buyers are typically cash-rich and price-inelastic at the margin.
  • Investor-flow deterrent: the surcharge may deter overseas-investor flows into UK housing-development pipelines, where the investor capital can support new supply. A surcharge increase tightens the deterrent.

Counter-arguments from supporters of the surcharge increase emphasise the cumulative effect of a sustained policy direction (each surcharge rate increase shifts the marginal cost of overseas-cash purchases incrementally), the political-signalling effect of a tax measure focused specifically on overseas investors, and the revenue-raising element (the surcharge generates SDLT revenue at low administrative cost). The page does not take a position on the policy debate; it tracks the policy state and provides the worked SDLT figures at both rates.

Stacking with the 5% additional dwellings surcharge

The Schedule 9A non-resident surcharge stacks additively on top of the 5% additional dwellings surcharge under FA 2003 Schedule 4ZA. The 5% rate is the operative additional dwellings surcharge rate from 31 October 2024, introduced by FA 2025 s.51 (replacing the previous 3% rate). Both surcharges apply to residential transactions and operate via the band-additive computation under FA 2003 s.55B (Schedule 4ZA) and FA 2003 s.55C (Schedule 9A).

For a non-resident buyer who already holds a dwelling anywhere in the world, both surcharges apply on a UK purchase. The combined surcharge load is 5% (Schedule 4ZA) plus 2% (Schedule 9A) equals 7% additional on top of the standard residential Table A rates. At a hypothetical 3% Schedule 9A rate, the combined surcharge load would be 8% additional. On the top residential band (consideration above £1.5 million), the combined effective rate at 7% surcharge is 19% (12% standard plus 7% surcharge); at 8% surcharge, the combined effective rate would be 20%.

The worldwide-property mechanics that trigger the Schedule 4ZA surcharge for non-resident buyers are covered in our how owning property abroad leads to higher SDLT rates page. The page maps the three statutory routes (Schedule 4ZA worldwide reach, Schedule 9A non-resident surcharge, Schedule 6ZA FTB-relief disapplication) through which overseas property ownership raises a UK buyer's SDLT bill. The current page covers the policy direction on the non-resident surcharge specifically.

Worked examples at both rates

Three worked examples for a sole non-resident buyer with no other property (Schedule 9A surcharge applies; Schedule 4ZA does not):

£500,000 purchase. Standard residential SDLT under Table A: 0% on £125,000 plus 2% on £125,000 (£2,500) plus 5% on £250,000 (£12,500) equals £15,000. With 2% non-resident surcharge added band-by-band under FA 2003 s.55C: 2% on £125,000 (£2,500) plus 4% on £125,000 (£5,000) plus 7% on £250,000 (£17,500) equals £25,000. Additional cost of non-residence: £10,000. At a hypothetical 3% rate: 3% on £125,000 (£3,750) plus 5% on £125,000 (£6,250) plus 8% on £250,000 (£20,000) equals £30,000. Differential between 2% and 3% rates: £5,000.

£1,000,000 purchase. Standard residential SDLT: 0% on £125,000 plus 2% on £125,000 (£2,500) plus 5% on £675,000 (£33,750) plus 10% on £75,000 (£7,500) equals £43,750. With 2% non-resident surcharge: £63,750. Differential: £10,000 added by the surcharge. At a hypothetical 3% rate: £73,750. Differential between 2% and 3% rates: £10,000.

£2,000,000 purchase. Standard residential SDLT: 0% on £125,000 plus 2% on £125,000 (£2,500) plus 5% on £675,000 (£33,750) plus 10% on £575,000 (£57,500) plus 12% on £500,000 (£60,000) equals £153,750. With 2% non-resident surcharge: £193,750. At a hypothetical 3% rate: £213,750. Differential between 2% and 3% rates: £20,000.

The differential between the 2% and 3% rates is consistently 1% of the purchase price (the surcharge is added linearly across all bands). At the £2 million transaction band typical of upper-prime London purchases, the 1-percentage-point increase represents £20,000 of additional SDLT; at the £5 million transaction band (top of the prime market), £50,000.

Combined non-resident plus additional dwellings examples

For a non-resident buyer with an additional-dwellings position (worldwide-property ownership over £40,000 under Schedule 4ZA, or spouse-aggregation triggering the surcharge), both surcharges apply.

£500,000 purchase, non-resident plus additional dwellings. Standard residential SDLT £15,000. Add 5% Schedule 4ZA on each band: 5% on £125,000 plus 7% on £125,000 plus 10% on £250,000 equals £6,250 + £8,750 + £25,000 = £40,000. Add 2% Schedule 9A on each band on top: 7% on £125,000 plus 9% on £125,000 plus 12% on £250,000 equals £8,750 + £11,250 + £30,000 = £50,000. At a hypothetical 3% non-resident rate: 8% on £125,000 plus 10% on £125,000 plus 13% on £250,000 equals £10,000 + £12,500 + £32,500 = £55,000.

£1,000,000 purchase, non-resident plus additional dwellings. Standard residential SDLT £43,750. With 5% Schedule 4ZA: £93,750. With 5% + 2% surcharges: £113,750. At hypothetical 3% non-resident rate: £123,750.

The combined non-resident-plus-additional-dwellings position is the highest SDLT load on UK residential property. A non-resident buy-to-let buyer at £1 million pays £113,750 of SDLT at the current rates, or 11.4% effective. At the hypothetical 3% rate, the figure rises to £123,750 (12.4% effective). For high-end non-resident BTL portfolios, the combined surcharge load is a material element of the entry cost.

The SDLT-specific 183-day residence test

The Schedule 9A residence test under paragraph 4 is the SDLT-specific test for whether a buyer is non-resident for the surcharge. It is different from the Statutory Residence Test under FA 2013 Schedule 45 used for income tax and capital gains tax. The SDLT-specific test asks whether the buyer was present in the UK for at least 183 days during any continuous period of 365 days that begins not earlier than 364 days before the effective date of the transaction and ends not later than 365 days after the effective date.

The test has three distinctive features. First, the 365-day period is flexible: it can start up to a year before the transaction and end up to a year after. The buyer is not required to be UK-resident at the effective date itself; the test looks at any qualifying 365-day window spanning the transaction. Second, the 183-day threshold is fixed: presence for fewer than 183 days in every possible 365-day window means the buyer is non-resident. Third, the post-transaction year is available for the refund route: a buyer who fails the test at completion can claim a refund of the 2% surcharge paid at completion if the test is subsequently satisfied within 12 months after the transaction (i.e., the buyer becomes UK-resident under the SDLT-specific test in the year after completion).

The distinction from the FA 2013 SRT is a recurring source of drift for cross-border buyers. Many buyers who are UK-resident under the SRT for income tax purposes are non-resident under the SDLT-specific test, particularly in the year of arrival in the UK or in years of significant overseas absence. The two tests answer different questions and produce different outcomes on the same buyer.

Commencement-date discipline for transactions in flight

Past SDLT rate changes have typically followed the pattern that contracts exchanged before the announcement date of the rate change but completing after may be at the old rate under transitional or grandfathering rules; contracts exchanged after the announcement are at the new rate. The exact transitional provisions depend on the wording of the Finance Act that legislates the change. The 5% Schedule 4ZA rate (introduced by FA 2025 s.51 with effect from 31 October 2024) operated on this pattern: contracts exchanged before 31 October 2024 but completing after that date were at the 3% rate; contracts exchanged after 31 October 2024 were at the 5% rate.

If a future Finance Bill legislates the Labour 2% to 3% Schedule 9A increase, the commencement date and transitional provisions would be set out in the Act itself. Buyers with transactions in progress at the time of any announcement should take immediate advice on the exchange-date discipline and the implications for completion timing. The page will be updated to reflect the legislated position when known.

Practical guidance for non-resident buyers planning a UK purchase

Five planning steps for a non-resident buyer facing a UK home purchase in the 2025-26 policy window:

  1. Confirm residence status under the SDLT-specific 183-day test. Do not rely on the FA 2013 Statutory Residence Test. The Schedule 9A paragraph 4 test is different and produces different outcomes. Document UK presence for the relevant 365-day windows.
  2. Model SDLT at both rates. Calculate the SDLT at the current 2% Schedule 9A rate (current statutory position as at 26 May 2026) and at a hypothetical 3% rate. The 1-percentage-point differential is £10,000 per million pounds of purchase price; the figure is material for planning and affordability modelling.
  3. Surface the worldwide-property triangulation. Check whether the additional dwellings surcharge under Schedule 4ZA also applies (worldwide-property ownership over £40,000; spouse-aggregation under paragraph 9). Where both surcharges apply, the stacking effect is substantial; see our how owning property abroad leads to higher SDLT rates page for the three-routes analysis.
  4. Evaluate FTB-relief eligibility. First-time buyer relief under Schedule 6ZA is not residence-conditional. A non-resident buyer with no prior worldwide property ownership can claim FTB relief; the Schedule 9A surcharge still applies on top.
  5. Engage UK conveyancing and tax advice early. The SDLT return is filed at completion and the surcharges apply on the SDLT1; getting the calculation right at the return-filing stage is materially easier than amending later. Disclose all worldwide property and spouse / civil partner property to the conveyancer.
