Autumn Budget 2026 – What it means for Hong Kong landlords and buyers

For Hong Kong buyers and landlords with UK property interests, the Autumn Budget 2026 was more measured than many had feared. The Chancellor left Capital Gains Tax, employment income and dividend tax rates unchanged, while also keeping the £2 million threshold for the High Value Council Tax Surcharge.

There was some welcome support for first-time buyers through the new Your First Home scheme. However, landlords face a further increase in tax on property income from April 2027, taking the total increase over current rates to four percentage points.

For anyone buying, letting or selling property in the UK, the key question is not simply what has changed, but when the changes take effect and how they may affect the cost of owning property.

UK Budget 2026 at a glance for Hong Kong owners

Stamp duty: What Hong Kong buyers will pay

For Hong Kong residents buying residential property in England or Northern Ireland, SDLT remains an important cost. Under the current rules, the 2% non-UK resident surcharge can apply, alongside the 5% higher-rate surcharge where the purchase is an additional residential property.

The Budget did not introduce the wider SDLT reform that some in the property sector had hoped for. For buyers, this means the existing rates and surcharges remain relevant when calculating the cost of a purchase.

Stamp duty continues to be one of the biggest costs associated with moving home or acquiring additional property. The absence of reform will therefore be disappointing for those hoping for a simpler or more flexible system.
For an off-plan purchase, buyers should still check the SDLT position closer to completion, as the applicable rules are based on the transaction date.

Tax on rental income: a further increase from April 2027

For individual landlords, one of the biggest Budget announcements was a further 2 percentage-point increase in tax on property income.

From 6 April 2027, the rates will rise to 24% for basic-rate taxpayers, 44% for higher-rate taxpayers and 49% for additional-rate taxpayers. This means property income will ultimately be taxed at rates four percentage points higher than the current 20%, 40% and 45% rates.

For Hong Kong landlords receiving UK rental income, this makes it particularly important to review projected rental profits and understand how the new rates could affect their overall tax position.

The increase will also apply to property income distributions from UK REITs, although the impact on non-resident investors can depend on applicable treaty relief and the structure used.

Capital Gains Tax if you sell

There was some welcome certainty for property investors on Capital Gains Tax. The Budget did not announce an increase to the main CGT rates.

Hong Kong residents selling UK residential property can still be liable for UK CGT on a gain. Non-UK residents must generally report disposals of UK residential property to HMRC and pay any CGT due within 60 days of completion.

While CGT was an area of considerable Budget speculation, the decision to leave the main rates unchanged provides greater certainty for owners considering a future sale. The tax position will still depend on the individual’s circumstances and the property involved.

Council Tax and the “mansion tax”

The Budget also provided welcome clarity on the High Value Council Tax Surcharge, often referred to as the “mansion tax”.

The £2 million threshold has been retained, rather than lowered. The surcharge will apply from April 2028 to qualifying residential properties in England valued at £2 million or more.

The annual surcharge will range from £2,500 for properties worth £2 million to £2.5 million to £7,500 for properties worth £5 million or more. The liability will sit with the property owner rather than the tenant.
For Hong Kong owners of high-value London property, this means the £2 million threshold remains an important figure to keep in mind when assessing future ownership costs.

First-time buyers: support is coming, but only for new builds

One of the more positive housing measures is the new Your First Home scheme.

Eligible first-time buyers will be able to purchase a new-build home with a deposit as low as 2.5%, supported by a 20% government equity loan. The loan will be interest-free for the first five years. Income and property price caps will apply.

Pre-registration is expected by the end of December 2026, with full applications from February 2027 and the first loans issued from April 2027.

The scheme should help reduce the deposit barrier for some first-time buyers and could support activity in the new-build market. However, it is disappointing that the support is not available to buyers purchasing existing homes.

Other changes landlords should know

The Budget also confirmed a 2 percentage-point increase in tax on savings income from April 2027, taking the rates to 24%, 44% and 49%.

Making Tax Digital remains another important consideration. Landlords with qualifying income above the relevant thresholds are being brought into the system, meaning affected landlords will need to keep digital records and submit quarterly updates through compatible software. MTD only currently applies to overseas landlords who have a UK National Insurance number.

Inheritance Tax also deserves attention. UK property remains within the UK IHT regime, while the rules for long-term UK residents can bring overseas assets within scope, subject to the detailed conditions.

What Hong Kong landlords and buyers should do now

Before making any major property decision, Hong Kong investors should:

• Check that their 2025/26 UK tax return is on track for the 31 January 2027 filing and payment deadline.
• Review whether they are correctly registered under the Non-Resident Landlord Scheme.
• Estimate the impact of the April 2027 property income tax rates on rental profits.
• Consider how the higher savings income rates may affect their wider tax position.
• If buying, rerun the SDLT calculation based on the rules applying at completion.
• Take professional tax advice before selling or changing ownership, particularly when considering personal versus company ownership.
