How much more tax do foreigners pay when buying a house in the UK? 2% surcharge and the 183-day rule
The same £500,000 house, some people pay £15,000 in stamp duty, some pay £50,000. It's not the house that's different, it's whether you are considered a "UK resident" in the eyes of HMRC — and this determination has nothing to do with your visa status at all .
In the process of buying a house in the UK, which step is legally binding?
Many people think that an offer being accepted is a sure thing. It's not. In England and Wales, "Offer accepted" has no legal binding, the seller can accept a higher price at any time (commonly known as gazumping), and all the survey fees and lawyer fees you have already paid will be wasted.
The real watershed is Exchange of contracts (Exchange of contracts): After this step, the contract becomes effective, and the buyer usually has already paid a deposit of 5%–10%, which will be confiscated if they regret. The exchange of contracts to Completion (Handover) usually takes several days to several weeks.
📌 Within 14 days after moving in, you must submit the SDLT return and pay the tax (England, Northern Ireland). There will be penalties and interest if late. Usually handled by your conveyancer, but the legal responsibility is yours. Scotland uses LBTT, Wales uses LTT, with completely different tax structures - don't copy.
Two extra payments for non-residents buying a house: 2% surcharge + 5% second property tax
The standard residential tax rate from April 1, 2025, is tiered and progressive: 0% for under £125,000, 2% for £125,000–£250,000, 5% for £250,000–£925,000, 10% for £925,000–£1.5 million, and 12% for over £1.5 million. In addition, foreign buyers may face two additional layers:
① 2% Non-resident surcharge (effective April 1, 2021); ② 5% Additional residential high tax rate (increased from 3% to 5% on October 31, 2024), which will be triggered if you already own a residence globally - buying the first property here is considered as "second property" if you have one apartment domestically.
| Buy a £500,000 property | Combined situation | Payable SDLT |
|---|---|---|
| Residents · First-time Buyer | FTB Relief | £10,000 |
| Residents · Single Dwelling | Standard Rate | £15,000 |
First-time buyer relief (exempt for properties under £300,000, 5% on the portion between £300,000 and £500,000) requires that you have never owned a home worldwide, and the property price does not exceed £500,000.
The 183 days of SDLT and the 180 days of permanent residency are completely different things.
This is the most common pitfall for Chinese buyers. The SDLT resident test only looks at one thing: have you been in the UK for 183 days or more in the 12 months before the transaction date, ? If not, you are considered a non-resident, even if you hold a Skilled Worker visa, have a UK address, and pay taxes in Council Tax; you will still have to pay an extra 2%.
While the 180 days for permanent residency (ILR) is in reverse: within any 12-month period, the time spent outside the UK () must not exceed 180 days. One number counts the days "in the UK," and the other counts the days "not in the UK," with opposite criteria; never apply them to each other. To accurately calculate both lines, it's much safer to use the 永居计算器 app to precisely calculate day by day.
The good news is that 2% can be refunded: if you have lived for 183 days within any continuous 365 days between and , you can apply for a refund within 2 years from the date of the transaction. People who just arrived in the UK and bought a property often automatically meet the criteria after a few months - but HMRC will not refund automatically, you need to submit a correction yourself. When married or in a civil partnership, if one person meets the residency test, both are usually treated as residents. If you are unsure whether you qualify, you can pay £5 on justiscript.com to get a written response from a UK practicing lawyer within 24 hours, which is much cheaper than paying taxes later.
After purchase: 20% is withheld for rental, and declaration is required within 60 days of selling the house.
Rental : The Non-resident Landlord Scheme applies to landlords who are based overseas, and agents or tenants will usually deduct 20% from the rent and pay it to HMRC by default. After submitting NRL1 and getting approval, you can receive the full rent and declare it yourself through Self Assessment - note that this only changes the timing of tax payment, not that it is tax-free.
Sell property : Non-residents disposing of UK properties, even if there is a loss, even if there is zero tax , must report through HMRC's UK Property Account within 60 days after completion. Residential capital gains tax 18% / 24% (depending on tax bracket), the individual allowance for the 2026/27 tax year is only £3,000. The penalty for late reporting within 60 days is heavier than many people think.
New Changes in 2026: Luxury Property Additional Fee and Increased Rent Tax Rate in 2027
The autumn budget on November 26, 2025, did not touch the stamp duty, but dropped two "bombs": first, a High Value Surcharge for residential properties valued over £2 million, an annual amount of approximately £2,500–£7,500, with valuation work to be carried out in 2026 and collected together with Council Tax starting April 2028; second, the tax rate on rental income will be increased by 2 percentage points for each bracket starting April 2027. Many old apartments in central and inner London are near the threshold, so it's worth asking clearly before placing an order now. Specific details are subject to final legislation and GOV.UK announcement.
Buying property in the UK will not give you any visa or permanent residency status.
The UK does not have a "buying a house to immigrate" path. The Tier 1 Investor visa program has long been closed, and property ownership does not count as any points for any visa or ILR application. ILR checks the length of residence, number of days abroad, Life in the UK, and English language skills — owning a property cannot offset even one day of excessive time abroad. Conversely, you can still buy a house and own it without having a legal status. If you separate these two issues, your decision will become much clearer.

My judgment is that the biggest mistake of foreign buyers is not choosing the wrong area, but failing to calculate whether the 2% could be waited for or refunded before renewing the contract -- delaying the transaction by two months, a £500,000 house might save £10,000, while most people only find out about this rule after signing the contract.
The above table of four identities for SDLT is suitable for people who are looking at houses, or those who have just received an offer but haven't changed their contract yet. It's worth saving and referring to when communicating with a conveyancer.
