Expat Returning to UK: How to Reclaim the 2% Stamp Duty Surcharge
If you bought a UK property as a non-resident and later moved back, you may be entitled to a full refund of the 2% non-resident SDLT surcharge.
In this article
Key Takeaways
- British expats and other non-residents can reclaim the 2% non-resident SDLT surcharge if they become UK resident after purchase — saving thousands of pounds.
- The reclaim window is 2 years from the purchase completion date. You must spend 183 days in any continuous 365-day period starting up to 364 days before AND ending up to 365 days after the completion date.
- Applications are made online through HMRC by amending your original SDLT return. You need your UTRN, completion date, total SDLT paid, purchase price, and UK bank details.
- If an agent (solicitor or accountant) applies on your behalf, they need a signed authority document from you before HMRC will process the claim.
- The 2% non-resident surcharge is separate from the 5% additional property surcharge. Expats returning to the UK may be able to reclaim both under different relief rules.
- On a £500,000 property, the 2% surcharge is worth £10,000. On a £1,000,000 property it is £20,000 — making the reclaim application highly worthwhile for anyone planning to return.
- There is no minimum period you must live in the UK after meeting the 183-day test. You simply need to have accumulated 183 days of physical presence within the qualifying window.

Overview: The Expat Surcharge Situation
Many British expats and other non-residents buy UK property while still living abroad — perhaps to prepare for an eventual return, or to house family members. At the time of purchase, they pay the 2% non-resident stamp duty surcharge because they have not spent 183 days in the UK in the required look-back window.
The good news: HMRC built a reclaim mechanism into the rules from the start. According to GOV.UK guidance on non-UK resident SDLT refunds, if you subsequently become UK resident — by spending 183 days in the UK in the qualifying window — you can amend your original SDLT return and receive a full refund of the 2% surcharge.
Key Point: You Do Not Need to Have Intended to Return
The reclaim right applies to any purchaser who meets the 183-day test after the event — not just those who planned to return. If your circumstances changed after purchase and you ended up spending 183+ days in the UK within 2 years, you are entitled to the refund regardless of your original intentions.
Who Can Reclaim the Surcharge?
You can reclaim the 2% non-resident surcharge if all of the following apply:
- You purchased residential property in England or Northern Ireland (SDLT applies)
- You paid the 2% non-resident surcharge on the purchase
- After completion, you spent 183 days or more in the UK in a qualifying continuous 365-day period
- That 365-day period started no more than 364 days before the completion date
- That 365-day period ended no more than 365 days after the completion date
- You apply within 2 years of meeting the 183-day test (or within 12 months of filing your SDLT return, if later)
Scotland and Wales: Different Rules
Scotland (LBTT) and Wales (LTT) do not have a 2% non-resident surcharge. If you bought in Scotland or Wales, there is no non-resident surcharge to reclaim. However, if you also paid the Additional Dwelling Supplement in Scotland, separate reclaim rules apply under Scottish legislation.
Understanding the Qualifying 183-Day Window
The qualifying window for the reclaim is more flexible than the initial purchase test. The 365-day period in which you must accumulate 183 UK days can start up to 364 days before completion and must end no later than 365 days after completion. This gives a total possible window of up to 729 days, anchored around the completion date.
| Parameter | Rule |
|---|---|
| Earliest start of 365-day window | 364 days before completion date |
| Latest end of 365-day window | 365 days after completion date |
| Days required in UK within that window | 183 days (at midnight) |
| Application deadline | 2 years after meeting the 183-day test |
| Alternative deadline | 12 months after filing original SDLT return (if later) |
Per the GOV.UK rates guidance, the key is to find a single continuous 365-day period within that wider anchor window that contains 183 or more UK presence days. Days of presence are counted using the same midnight rule as the initial purchase test.
Step-by-Step Refund Process
The refund is made by amending your original SDLT return via the HMRC online service. Here is the process from start to finish:
Confirm you have met the 183-day test
Count your UK days carefully using the midnight rule. Identify a continuous 365-day window (within the anchor period) where you hit 183 days. Note the exact date you met the threshold — this starts your 2-year claim deadline.
Gather your documentation
You will need: your Unique Transaction Reference Number (UTRN) from the original SDLT return, the exact completion date, the total SDLT paid (including the surcharge), the purchase price, and your UK bank account details for the repayment. Keep evidence of your UK day-count (passport stamps, flight records, bank statements).
Log in to the HMRC SDLT online service
Visit GOV.UK and use the SDLT online amendment service. You will need a Government Gateway ID linked to your previous SDLT return. If your solicitor filed the return on your behalf, they may need to provide access or you may need to create your own Government Gateway credentials.
Amend the original SDLT return
Select “amend a return” and enter your UTRN. Update the non-resident status field to reflect that you have now met the 183-day test. The system will recalculate the SDLT liability without the 2% surcharge and show the amount due for repayment.
Confirm bank details and submit
Provide your UK bank account sort code and account number for the refund. Submit the amended return. HMRC will review the claim and, if accepted, process the repayment to your bank account.
Receive the repayment
HMRC typically processes repayments within 15 working days of receiving a complete application. For complex cases or where additional evidence is requested, processing can take longer. If you have not heard within 30 days, contact HMRC's SDLT helpline.
Important: UTRN vs UTR
Your UTRN (Unique Transaction Reference Number) is specific to your SDLT transaction — it is different from your UTR (Unique Taxpayer Reference for income tax). Your UTRN appears on the SDLT certificate (SDLT5) issued after your original return. Your solicitor should have a copy if you do not.
Information Required for the Claim
Before starting the HMRC amendment process, have these details ready. Missing information will delay processing.
| Information Needed | Where to Find It |
|---|---|
| UTRN (Unique Transaction Reference Number) | SDLT5 certificate from original transaction; solicitor's file |
| Completion date | Completion statement or title register |
| Total SDLT paid (incl. surcharge) | SDLT return or completion statement |
| Purchase price | Transfer deed or completion statement |
| UK bank account details | Your UK bank sort code and account number |
| Date 183-day test met | Your own day-count records; passport/travel evidence |
| Evidence of UK days (if queried) | Passport stamps, flight records, bank statements |
Worked Example: £600,000 Purchase
Marcus is a British expat living in Dubai. He completes the purchase of a £600,000 London flat on 1 April 2025. At that time, he has only spent 70 days in the UK in the prior 12 months. He pays the 2% non-resident surcharge.
SDLT Paid at Completion (Non-Resident, Main Home)
Marcus moves back to London on 1 September 2025 and starts a new job. By 1 March 2026, he has accumulated 183 days of UK presence since returning (1 Sept 2025 – 1 Mar 2026). The qualifying 365-day window that contains these days (e.g. 2 April 2025 – 1 April 2026) overlaps with the allowed reclaim anchor period.
| Timeline Event | Date |
|---|---|
| Completion date | 1 April 2025 |
| Moved back to UK | 1 September 2025 |
| 183rd UK day reached | 1 March 2026 |
| Reclaim application deadline | 1 March 2028 (2 years from meeting test) |
| Anchor window (completion +/- 365 days) | 2 April 2024 – 1 April 2026 |
| Qualifying window used | 2 April 2025 – 1 April 2026 (contains 183+ UK days) |
Marcus Reclaims £12,000
Marcus amends his SDLT return online before 1 March 2028 and receives £12,000 back to his UK bank account. For more detail on the full refund framework, see our stamp duty refund guide.
If You Also Paid the 5% Additional Property Surcharge
Many expats buying a UK property also own property abroad, meaning both the 2% non-resident surcharge and the 5% additional dwelling surcharge applied at purchase. The non-resident reclaim and the additional property reclaim are separate processes with different qualifying conditions.
| Surcharge | Reclaim Condition | Deadline |
|---|---|---|
| 2% non-resident surcharge | Spend 183 days in UK in qualifying window | 2 years from meeting the 183-day test |
| 5% additional dwelling surcharge | Sell the previous main residence within 36 months of purchase | 12 months after sale of previous property |
Example: Emma, an expat who owns a flat in Paris, bought a £500,000 London flat paying £46,250 (standard + 5% ADS + 2% NR). She moves back to London and meets the 183-day test. She can reclaim £10,000 (2% NR surcharge). If she also sells the Paris flat within 36 months of the London purchase, she can separately reclaim £25,000 (5% additional property surcharge). Total potential refund: £35,250. See our refund claim process guide for the additional dwelling reclaim steps.
Using an Agent to Make the Claim
You can authorise a solicitor, accountant, or other agent to amend the SDLT return on your behalf. Before HMRC will process a claim made by an agent, the agent must hold a signed authority document from you confirming they are authorised to act. This is typically a short letter or standard agent authorisation form.
Agent Tip: Check Whether the Original Solicitor Still Has Your File
If your original conveyancing solicitor still has access to the SDLT return, they may be the easiest agent to use — they already have your UTRN and transaction details. Contact them early. Many firms charge a flat fee (typically £150–£300) for processing SDLT refund claims.
How Long Does the Refund Take?
HMRC does not publish a fixed processing time for non-resident SDLT refunds. Based on the standard SDLT amendment process, straightforward cases typically complete within 15–20 working days of HMRC receiving a fully complete application.
| Scenario | Typical Timeline |
|---|---|
| Complete online application, all details correct | 15–20 working days |
| HMRC requests additional evidence | 30–60 working days |
| Complex cases (e.g. dispute over day count) | 60–90+ working days |
If you have not received the repayment within 30 working days of submitting a complete application, contact HMRC's Stamp Taxes helpline: 0300 200 3510 (Monday to Friday, 8:30am–5pm).

Frequently Asked Questions
How long do I have to reclaim the non-resident stamp duty surcharge?
You must apply within 2 years of the date you met the 183-day UK presence test. There is an alternative deadline of 12 months after filing your original SDLT return, whichever is the later of the two. Missing the deadline means you lose the right to reclaim — there is no discretion to extend it.
Do I need to have lived in the property to reclaim the surcharge?
No. The reclaim right for the 2% non-resident surcharge is based solely on meeting the 183-day UK presence test — you do not have to have lived in the purchased property itself. This is different from the 5% additional dwelling surcharge reclaim, which has its own separate conditions involving selling a previous main residence.
What happens if I have already sold the property before meeting the 183-day test?
You can still reclaim the surcharge even if you have sold the property, provided you meet the 183-day test within the qualifying window and apply before the deadline. The reclaim right is not conditional on still owning the property.
Can I reclaim both the 2% non-resident surcharge and the 5% additional property surcharge?
Yes, but through separate processes. The non-resident surcharge reclaim requires meeting the 183-day test and applying via HMRC online. The additional dwelling surcharge reclaim requires selling the previous main residence within 36 months of purchase and applying within 12 months of that sale. Both can be done independently.
What is the UTRN and where do I find it?
The UTRN (Unique Transaction Reference Number) is the reference number assigned to your specific SDLT return when it was originally filed. It appears on the SDLT5 certificate that HMRC issued after your original return. Your conveyancing solicitor should have a copy in your completion file. It is different from your UTR (Unique Taxpayer Reference) used for income tax.
