UK property taxation is rarely simple. Between Stamp Duty Land Tax (SDLT), Income Tax on rental profits, Capital Gains Tax (CGT), Inheritance Tax (IHT) and the Annual Tax on Enveloped Dwellings (ATED), buyers and investors face a layered system that has changed significantly in recent years. Whether you live in the UK or hold property from overseas, understanding how these taxes interact in 2026 is essential for protecting your returns and staying compliant with HMRC.

This guide breaks down each of the main residential property taxes, explains the current rates in plain English, and highlights what owners need to plan for in the year ahead.

The State of the UK Residential Market in 2026

The housing market has cooled compared with the post-pandemic peak, but it has not crashed. Activity is uneven across regions: parts of the North and Midlands continue to see steady growth, while transaction volumes in central London, the South East and parts of Scotland have softened. Affordability pressure, higher mortgage costs and the reduction in stamp duty thresholds from April 2025 have slowed the pace of sales, particularly for second homes and buy to let purchases.

For sellers, the message is realism on price. For buyers, especially first time buyers, the slower market has created room to negotiate. And for landlords, recent tax changes mean the cost of acquiring and holding residential property has risen, making careful tax planning more important than ever.

Stamp Duty Land Tax (SDLT) in 2026

Stamp Duty Land Tax applies to residential property purchases in England and Northern Ireland. Scotland uses Land and Buildings Transaction Tax (LBTT) and Wales uses Land Transaction Tax (LTT), each with its own bands.

The temporary higher SDLT thresholds ended on 31 March 2025, and the rates that took effect on 1 April 2025 remain in force throughout 2026.

Standard SDLT rates for main residences

First time buyer relief

First time buyers in England and Northern Ireland pay no SDLT on the first £300,000 of a property priced up to £500,000, and 5% on the portion between £300,001 and £500,000. If the price exceeds £500,000, the relief is lost entirely and standard rates apply to the full purchase price.

Additional property surcharge

Anyone buying a second home or buy to let property pays a 5% surcharge on top of each standard band (raised from 3% on 31 October 2024). The surcharge applies where the buyer already owns another residential property anywhere in the world and is not replacing their main residence.

Non resident surcharge

Buyers who are not UK resident for SDLT purposes pay an additional 2% on top of all other applicable rates. This is in addition to the 5% additional property surcharge if it also applies.

Corporate purchases

Where a residential property costing more than £500,000 is acquired by a company or other non natural person, a flat rate of 17% applies to the whole purchase price, unless a relief is available (for example, for genuine property rental or development businesses).

SDLT must be reported and paid within 14 days of completion, normally through the buyer’s solicitor.

Annual Tax on Enveloped Dwellings (ATED)

ATED is an annual charge on UK residential property worth more than £500,000 that is held by a company, a partnership with at least one corporate member, or a collective investment scheme. The aim is to discourage holding high value homes inside a corporate envelope purely for tax planning reasons.

Key points for 2026:

• The chargeable period runs from 1 April to 31 March.
• Returns and payment for properties within ATED on 1 April 2026 are due by 30 April 2026, covering the 2026 to 2027 period.
• ATED charges rose by 3.8% from 1 April 2026, in line with the September 2025 CPI.
• The current valuation cycle uses property values as at 1 April 2022 (or the acquisition date if later).
• Reliefs are available for property rental businesses, property developers, property traders and certain other genuine commercial uses, but a relief declaration return must be filed each year.

Late filing or late payment attracts fixed and tailored penalties plus interest, so corporate owners should diarise the April deadline carefully.

Capital Gains Tax on Residential Property

If you sell a residential property that is not your main home, any gain is potentially subject to Capital Gains Tax. This typically affects buy to let landlords, owners of second homes and inherited properties.

Current CGT position for the 2025 to 2026 and 2026 to 2027 tax years:

• Basic rate taxpayers pay 18% on residential property gains.
• Higher and additional rate taxpayers pay 24%.
• The annual exempt amount is £3,000 per individual.
• Gains and CGT due must be reported and paid within 60 days of completion using HMRC’s online property disposal service.

Your main home is normally exempt under Private Residence Relief, provided it has been your only or main residence throughout your ownership. Spouses and civil partners can transfer assets between each other without triggering CGT, which often opens up planning opportunities before a sale.

Inheritance Tax on Property

Inheritance Tax applies to UK residential property regardless of how it is owned, including through offshore companies or trusts. The headline rate is 40% on the value of the estate above the available nil rate bands.

The main allowances are:

• The standard nil rate band of £325,000.
• The residence nil rate band of up to £175,000, where a qualifying main residence is passed to direct descendants (this tapers away for estates over £2 million).
• A 100% spouse or civil partner exemption, with unused nil rate bands transferable on the second death.

Lifetime gifts of property may also fall into the IHT net if the donor dies within seven years, with taper relief reducing the tax on gifts made between three and seven years before death. From 6 April 2027, most unused pension funds and death benefits will also be brought within the IHT estate, which may affect overall planning for property owning families.

Because the rules around trusts, gifts with reservation of benefit and overseas structures are complex, professional advice is strongly recommended before making any significant transfer.

Income Tax on Rental Profits

Landlords pay Income Tax on the net profit from letting residential property, at 20%, 40% or 45% depending on their total taxable income. Mortgage interest is no longer deductible as an expense; instead, individual landlords receive a basic rate (20%) tax credit. Many higher rate landlords have responded by holding property through a limited company, where finance costs remain fully deductible against corporation tax, although that route brings its own SDLT, ATED and extraction costs.

Should You Still Invest in UK Residential Property?

The combination of higher SDLT on additional properties, restricted mortgage interest relief, a smaller CGT annual exemption and elevated borrowing costs has narrowed the margins for buy to let investors compared with a decade ago. At the same time, rental demand remains strong in most UK cities, supply is constrained, and long term capital growth is still expected in many regions.

The right answer depends on your goals, your time horizon and how the property is structured. Key questions to work through before buying include:

• Will the property be held personally, jointly or through a limited company?
• How will the purchase be financed, and how does that affect your tax position?
• What is your plan for an eventual sale or transfer to family members?
• Are you a UK resident or non resident for SDLT, CGT and IHT purposes?

Getting these decisions right before exchange of contracts is far easier and cheaper than restructuring afterwards.

Frequently Asked Questions

What is the SDLT nil rate threshold in 2026?

The standard SDLT nil rate threshold is £125,000 for most buyers in England and Northern Ireland. First time buyers benefit from a higher £300,000 threshold on properties costing up to £500,000.

How much SDLT do landlords pay on a buy to let in 2026?

Landlords and second home buyers pay the standard SDLT rates plus a 5% surcharge on each band, starting at 5% on the portion up to £125,000 and rising to 17% above £1.5 million.

What rate of Capital Gains Tax do I pay when selling a buy to let?

For 2025 to 2026 and 2026 to 2027, CGT on residential property is 18% for basic rate taxpayers and 24% for higher and additional rate taxpayers, after deducting the £3,000 annual exempt amount. The gain must be reported and paid within 60 days of completion.

Who has to pay ATED?

ATED applies to companies, partnerships with a corporate member, and collective investment schemes that own UK residential property worth more than £500,000. Reliefs are available for genuine property businesses but must be claimed each year on an ATED return.

Is my main home subject to Capital Gains Tax?

In most cases no. Private Residence Relief usually exempts the sale of your only or main home from CGT, provided you have lived in it throughout your ownership and have not used part of it exclusively for business.
