The 183-day UK test for the non-resident stamp duty surcharge
183 days can change the SDLT result
The non-resident SDLT surcharge uses its own UK residence test. It is not the usual tax residence test.
- Count 183 days in a continuous 365-day period.
- Include days anywhere in the UK.
- Check every joint buyer separately.
- You may pay first and amend the return later.

The 183-day UK test for the non-resident stamp duty surcharge
The 183-day UK test for the non-resident stamp duty surcharge
Buying a home in England or Northern Ireland while based overseas does not automatically mean you must pay the extra 2% stamp duty charge, because the purchase has its own 183-day UK presence test. That test is separate. You may also need to pay first, then change the SDLT return later.
What this rule is about
The extra charge applies to certain non-resident property purchases and adds 2 percentage points to the normal SDLT rates. On a £300,000 purchase, it adds £6,000.
You might expect HMRC to use the usual tax residence test. It does not. Instead, this SDLT test focuses on a single property purchase, not a tax year.
That distinction matters because someone living abroad can still pass the SDLT test, while someone with many UK days over a long period can fail if those days do not sit within one continuous 365-day window. The dates must line up.
What the official source says
HMRC’s manual says an individual is UK resident for a purchase if they are present in the UK for at least 183 days in any continuous 365-day period within the relevant period. Schedule 9A sets that basic test.
- The relevant period starts 364 days before the effective date of the purchase.
- It ends 365 days after that effective date.
- You need 183 UK days within one continuous 365-day period.
- A day counts if you are in the UK at the end of that day.
- Days anywhere in the UK count, including Scotland and Wales.
- The property itself must be in England or Northern Ireland for this SDLT charge to be relevant.
- The basic rule covers purchases where all buyers are individuals.
- Other rules can apply in special cases, including some joint purchases by spouses or civil partners.
Do not total every UK day across the whole relevant period and stop there, because that period lasts much longer than one year and the 183 days must fit inside one unbroken 365-day stretch. The total alone will not do.
In practice, you can use a 365-day period before the purchase, after it, or one running across the purchase date. Each route can give the same answer.
What this means in practice
SDLT is due soon after the effective date, when you may not yet have enough future UK days to show that you will reach 183 days. At that point, the future has not happened.
If the other conditions for the extra charge are met, HMRC says you should complete the return as non-UK resident. You pay the extra 2% then.
Later, if your UK days reach 183 within a qualifying 365-day period, HMRC’s manual says you can amend the SDLT return and ask for the extra charge back. You can revisit it.
- Count days before the purchase first.
- Then check whether future UK days could complete a qualifying year.
- Keep records from the day you buy, not only from the day you move.
- File the SDLT return within 14 days where a return is required.
- Pay the extra amount if the return must be prepared on the non-resident basis.
- Revisit the position when later UK days take you to 183 days.
- Amend the return if the full test is then met and the other conditions allow it.
This can feel unfair: why pay extra when you expect to qualify later? SDLT attaches to a particular purchase. The return cannot assume future days that have not happened.
How to analyse it
Start with dates, not labels such as “expat” or “overseas buyer”, because where you live, your nationality and your normal tax residence provide background but do not answer this particular test. The calendar comes first.
- Identify the effective date of the purchase.
- Mark the day 364 days before it.
- Mark the day 365 days after it.
- List every day you were in the UK during that overall period.
- For each day, check where you were at the end of it.
- Test possible continuous 365-day periods for at least 183 UK days.
- Check each buyer separately if more than one person is buying.
- Check whether special spouse or civil partner rules apply.
- Check the other conditions for the non-resident surcharge.
- Compare the result with the position when the SDLT return is filed.
What should you ask? Not simply, “Have I spent 183 days in Britain?” Ask: “Can I show 183 UK days in one continuous 365-day period that falls within the allowed window?”
For joint buyers, this matters especially because one buyer’s qualifying year may differ from another’s, and no shared average exists. Count each person separately.
Example
Parvati buys a residential lease in England on 1 June 2025 for £300,000. She spends 200 days in the UK between 2 June 2025 and 1 June 2026. That is a continuous 365-day period, so she meets the 183-day test for that purchase.
Her SDLT return is due by 15 June 2025, however, and by then she has not spent 183 days in the UK; if the other conditions for the non-resident charge are met, HMRC’s manual says she files the return and pays the extra 2% on that basis. She pays first.
Once Parvati reaches the required number of days, she can amend the return and seek repayment of the £6,000 extra charge. That does not mean every buyer of a £300,000 property gets a refund. The other legal conditions still matter.
Now change one fact: if Parvati spends 200 days in the UK but those days do not fall within any one continuous 365-day period in the relevant period, she does not meet this basic test. The total number alone is not enough.
Why this can be difficult in practice
This is mainly a record-keeping problem, since people often remember trips only in broad terms while the test turns on individual days and on where they were at the end of each day. Travel days can change the count.
Joint buying adds another layer. The transaction can remain non-resident if one buyer does not meet the test, even where every other buyer does.
- Counting a tax year instead of a rolling 365-day period.
- Counting all UK days across the full relevant period.
- Ignoring days spent in Scotland or Wales.
- Counting a travel day without checking where you were at its end.
- Assuming one joint buyer’s UK days help another buyer.
- Assuming a future move to the UK removes the need to pay first.
- Forgetting that special rules may change the answer for spouses or civil partners.
- Assuming this test alone decides whether the extra charge applies.
If your solicitor has said the non-resident surcharge applies, inspect the day count closely, because a neat calendar supported by proof may help more than a broad account of where you usually live. Details matter here.
Key takeaways
- The SDLT residence test is different from the usual UK tax residence test.
- You need 183 UK days in one continuous 365-day period within the relevant window.
- At the end of each day is what counts.
- Days anywhere in the UK can count.
- Some buyers must pay the extra 2% first and amend the return later.

Official guidance
The pages below are HMRC’s guidance. Guidance is not law. It sets out how HMRC reads the legislation, and it is not binding on you, on a tribunal or on a court. Where guidance and the legislation differ, the legislation wins. HMRC can also change or withdraw guidance, and it may not cover your facts.
Where this is not settled
- The basic rule does not settle how the special rules apply to spouses, civil partners, trusts, partnerships, companies or other non-individual buyers.
- A day-count can depend on reliable evidence of where a person was at the end of each day.
- The source does not set out every condition needed before a transaction is treated as non-resident.
Evidence you would need
This kind of case is decided on the facts of the individual property. These are the records that usually settle it, and the ones an adviser would ask you for.
- The effective date of the purchase
- A day-by-day record of each buyer’s UK presence
- Travel records, passports, tickets, accommodation records or other proof of location
- Details of every buyer and whether they are spouses or civil partners
- The SDLT return and evidence of the amount of surcharge paid
