Owning a second property in the UK comes with a significant and growing tax burden. From the 3% Stamp Duty Land Tax surcharge you pay on purchase, to annual council tax premiums of up to 100%, rental income taxed at your marginal rate under the Section 24 restriction, and Capital Gains Tax of up to 24% when you sell -- understanding exactly what you owe is essential before you buy, let or dispose of a second home. This guide covers every major tax that applies to second homes and buy-to-let properties in England, Scotland and Wales for the 2026/27 tax year.
When you buy a second residential property in England or Northern Ireland, HMRC charges a 3% surcharge on top of every standard SDLT band. The surcharge has applied since April 2016 and was not changed in the Autumn Budget 2024 or Spring Statement 2025.
The standard SDLT rates for residential property are 0% up to GBP 125,000, 2% on the portion from GBP 125,001 to GBP 250,000, 5% from GBP 250,001 to GBP 925,000, 10% from GBP 925,001 to GBP 1.5 million, and 12% above GBP 1.5 million. The additional 3% is applied to every band, so the effective rates on a second home become 3%, 5%, 8%, 13% and 15%.
On a GBP 350,000 purchase the standard SDLT bill would be GBP 7,500. With the surcharge the bill rises to GBP 18,000 -- a difference of GBP 10,500 that must be paid within 14 days of completion.
A property counts as an additional dwelling if you already own -- or part-own -- another residential property anywhere in the world. This catches buyers who retain a property abroad. However, the surcharge does not apply if the property you are buying will replace your main residence and you sell the previous main home on the same day.
If you buy a new main home before selling the old one, the surcharge is triggered but you can claim a full refund from HMRC within 12 months of selling the previous main residence, as long as that sale happens within three years of buying the new property. The refund claim is made online or by post using an amendment to your SDLT return.
Scotland uses Land and Buildings Transaction Tax (LBTT) with an Additional Dwelling Supplement (ADS) of 8% on the full purchase price (not just the excess). Wales uses Land Transaction Tax (LTT) with a 4% higher residential rates surcharge. Both rates are higher than the English 3% surcharge, making second-home buying in Scotland and Wales considerably more expensive at the purchase stage.
Councils in England have been able to charge a council tax premium of up to 100% on furnished second homes since 1 April 2024, following powers granted by the Levelling-up and Regeneration Act 2023. This doubles the council tax bill on a property that is furnished and used as a second home but is not anyone\'s primary residence.
Not all councils have adopted the premium and some charge less than the maximum. You must check with the specific local authority where your second home is located. Popular tourist areas and coastal councils are most likely to have adopted or be considering the full 100% premium, as the measure was intended to discourage speculative second-home ownership in areas with housing shortages.
Exemptions exist for properties that are job-related dwellings (where someone is required to live elsewhere for work), granny annexes occupied by a relative, and properties that are undergoing major structural repair. An empty property left unfurnished may be treated differently under local authority discretion -- some councils charge a long-term empty premium after one or two years of vacancy.
In Wales, councils can charge a premium of up to 300% on second homes and long-term empty properties. In Scotland the maximum premium is 100%. These premiums are applied on top of the standard band valuation and can represent a very significant recurring annual cost, particularly in high-band areas.
If you let your second home commercially for short stays, it may be possible to have it assessed as a self-catering business for non-domestic rates rather than council tax, but strict occupancy thresholds apply and the abolition of the furnished holiday let regime from April 2025 has made this route harder to navigate.
Rental income from a second home is subject to UK income tax at your marginal rate. All rental receipts must be declared on a Self Assessment tax return. The rental profit -- income minus allowable expenses -- is added to your employment income, pension, savings interest and dividends to calculate your total taxable income for the year.
Allowable expenses include letting agent fees, accountancy fees directly related to the property, advertising costs, buildings and contents insurance, maintenance and repairs (but not improvements), ground rent, service charges, utility bills you pay when the property is empty, and travel costs for managing the property.
The Section 24 finance cost restriction, fully in force since April 2020, fundamentally changes the way mortgage interest is handled. You can no longer deduct mortgage interest from rental income before calculating profit. Instead, the full rental income is treated as profit, and you then receive a basic-rate tax credit equal to 20% of your mortgage interest costs. For a higher-rate taxpayer this is far less valuable than the old deduction.
Example: A landlord receives GBP 18,000 in rent and pays GBP 9,000 in mortgage interest. Under the old rules, the taxable profit would have been GBP 9,000 and the 40% tax bill GBP 3,600. Under Section 24, the taxable profit is GBP 18,000, the 40% tax on that is GBP 7,200, reduced by the 20% credit of GBP 1,800 (20% x GBP 9,000), giving a net tax bill of GBP 5,400 -- GBP 1,800 more per year.
If your rental income is GBP 1,000 or less in the tax year, the GBP 1,000 property allowance means you have no tax to pay and no need to register for Self Assessment solely for that income. Above GBP 1,000 you must register and file a return. The property allowance cannot be used alongside actual expense deductions -- you choose one or the other.
If you let a room in your own main home rather than a separate second property, you may qualify for Rent a Room relief of up to GBP 7,500 per year tax-free, but this does not apply to stand-alone second homes.
When you sell a second home that has never been your main residence, the full gain is liable to Capital Gains Tax. The gain is the sale proceeds minus the original purchase price, minus allowable acquisition costs (SDLT, legal fees), minus allowable improvement costs (not repairs), minus selling costs (estate agent fees, legal fees).
For 2026/27 the annual exempt amount (AEA) is GBP 3,000. Only gains above this threshold are taxed. The rate depends on your total taxable income in the year of disposal. If your income plus the gain stays within the basic-rate band (up to GBP 50,270), the CGT rate on residential property is 18%. Any portion of the gain that takes you above the basic-rate threshold is taxed at 24%.
There is no taper relief or indexation allowance for individuals on UK residential property. This means the full nominal gain is taxed even though part of it may simply reflect inflation. Long holding periods therefore do not reduce the percentage rate applied.
Private Residence Relief (PRR) exempts gains arising during periods when a property was your main home. If you lived in the property at any point, you can claim PRR for those years plus the final nine months of ownership regardless. This can significantly reduce the chargeable gain. Letting relief was restricted from April 2020 and now only applies where the owner also lives in the property -- rarely relevant for a pure second home.
Married couples and civil partners can each use their GBP 3,000 AEA by holding the property jointly. Transfers between spouses are at no gain/no loss, so restructuring ownership ahead of a sale can save CGT at the cost of planning. Note that the disposal must be reported to HMRC and any CGT paid within 60 days of completion using the UK Property Account -- a separate online service distinct from Self Assessment.
Non-residents selling UK residential property must also report within 60 days and pay Non-Resident CGT (NRCGT), which uses the same rates as resident CGT for residential property. The gain is calculated from April 2015 for non-residents unless they elect for the full gain to be used.
The furnished holiday let (FHL) tax regime was abolished on 6 April 2025 following the announcement in the Autumn Budget 2024. Properties that previously qualified as FHLs are now treated as ordinary residential rental properties for all tax purposes.
Before abolition, an FHL property had to be available for commercial letting for at least 210 days per year and actually let for at least 105 days. Properties meeting these tests enjoyed four significant tax advantages: profits counted as earnings for pension contribution purposes; capital allowances could be claimed on furniture, fixtures and equipment; Business Asset Disposal Relief (BADR) could apply on sale, capping the CGT rate at the prevailing BADR rate; and gains could be rolled over into replacement assets.
From April 2025, none of these advantages apply to new lettings. Existing FHL owners who had built a significant capital allowance pool should have taken advice before the abolition date. Any unclaimed pool will be treated as a revenue loss under the ordinary property income rules going forward, but the transitional position is complex.
For BADR purposes, owners who intended to sell and claim BADR needed to complete disposals before 6 April 2025 or hold a valid share-pooling election and meet the qualifying conditions before that date. Sales completing after April 2025 cannot use BADR on former FHL properties -- they are subject to the standard residential CGT rates of 18% or 24%.
If you operate a short-term let through platforms such as Airbnb, the income is now fully subject to Section 24 finance cost restrictions if you have mortgage finance. The GBP 1,000 property allowance still applies if annual receipts are below that threshold, but most active short-term lets will exceed this quickly.
A second home forms part of your taxable estate for IHT. The nil-rate band is GBP 325,000 and the residence nil-rate band (RNRB) of GBP 175,000 applies only to a main residence passed to direct descendants -- a second home does not qualify for the RNRB. At death, the estate value above the applicable thresholds is taxed at 40%.
Gifting a second home during your lifetime to reduce the estate value can trigger CGT at the point of transfer (market value is used as the disposal proceeds) and the gift remains within the estate for IHT purposes for seven years under the potentially exempt transfer (PET) rules. Taper relief reduces the IHT charge on gifts made three to seven years before death, but only on the tax itself, not the value assessed.
Holding a second home through a limited company avoids the Section 24 restriction because companies can deduct finance costs as business expenses. The company pays Corporation Tax at 19% (on profits below GBP 50,000) or 25% (above GBP 250,000) with marginal relief between those thresholds. Extracting profits as dividends then costs personal tax at 8.75% (basic), 33.75% (higher) or 39.35% (additional) above the GBP 500 dividend allowance. The company route also removes the RNRB position and can complicate IHT planning.
Transferring an existing personally-held property into a company is not straightforward. The transfer is treated as a sale at market value for CGT purposes and triggers SDLT (including the 3% surcharge) on the purchase by the company. These upfront costs mean the company route is usually only attractive for new acquisitions rather than transfers of existing portfolios.
If you are a non-UK domiciled individual and own a second home in the UK, the property itself is always within the scope of UK IHT regardless of your domicile status. From April 2025 the longstanding non-domicile IHT protections were reformed and most long-term UK residents are now taxed on worldwide assets. Specialist advice is essential in this area.
One further point: if you are classified as a property developer rather than an investor -- because you buy, improve and sell properties in quick succession -- HMRC may treat your profits as trading income rather than capital gains. This removes the GBP 3,000 AEA and the lower CGT rates, instead subjecting all profit to income tax at up to 45% plus National Insurance. The boundary between investment and trading is not always clear and depends on your overall pattern of activity, intention at purchase and holding periods.
The tax landscape for second homes is more challenging than at any point in the past decade. However, there are legitimate steps you can take to manage the burden within the law.
Use both annual exempt amounts. If you are married or in a civil partnership, holding the second home in joint names allows both of you to use the GBP 3,000 AEA on sale, saving up to GBP 1,080 in CGT (GBP 3,000 at 24% each, assuming higher-rate taxpayers). Transfers between spouses to adjust the ownership split before sale are at no gain/no loss.
Time the disposal carefully. If your employment income falls in a particular year -- perhaps due to redundancy, career break or retirement -- selling the property in that year may mean more of the gain falls into the 18% band rather than 24%, producing a meaningful saving on large gains.
Keep meticulous records of all capital expenditure. Improvements -- extensions, new kitchens, new bathrooms that increase the value of the property -- can be deducted from the gain. Routine repairs and maintenance cannot. The difference between the two is frequently disputed with HMRC and contemporaneous invoices are essential.
Consider the 60-day CGT reporting obligation. Since October 2021, all disposals of UK residential property must be reported and any CGT paid within 60 days of completion. Missing this deadline results in automatic late-filing penalties and interest on unpaid tax. Budget for the CGT bill before you agree a completion date.
Review mortgage strategy under Section 24. Interest-only mortgages maximise the interest cost eligible for the 20% credit but do not build equity. Some landlords have switched to repayment mortgages to reduce overall interest costs and simplify their tax position. Others have remortgaged at lower LTVs to reduce the Section 24 impact. There is no single right answer -- it depends on your overall financial position.
Check your council tax position annually. Premiums can change and your property\'s classification can shift. If you let the property commercially for sufficient days to qualify for non-domestic rates assessment, the rate may be lower than domestic council tax plus premium -- though this requires genuine commercial activity and HMRC scrutiny of short-term lets has increased.
Take professional advice before significant transactions. The interaction of SDLT, CGT, income tax and IHT on second-home decisions is complex. A chartered accountant or tax adviser with property expertise can often identify structuring options that self-research misses, and the cost of advice is typically a fraction of the tax at stake on a property worth GBP 200,000 or more.
