If you sell a second property in the UK in 2026/27, you’ll pay Capital Gains Tax at 18% (basic rate) or 24% (higher rate) on the gain above your £3,000 annual tax-free allowance, and you must report and pay HMRC within 60 days of completion.
For many in the UK, owning a second home is the ultimate financial milestone. Whether it’s a seaside cottage for family retreats, a flat in the city for work, or a buy-to-let investment intended to bolster a retirement fund, property remains a cornerstone of British wealth. However, the financial landscape of property ownership is shifting. As we move into the 2026/27 tax year, the rules surrounding Capital Gains Tax on Second Property have become more stringent, with tighter deadlines and evolving rates that can catch even seasoned investors off guard.
Selling a second home is no longer as simple as finding a buyer and pocketing the profit. Between the 60-day reporting window and the complexities of “Private Residence Relief,” the tax implications can be substantial. In this comprehensive guide, MyIVA UK breaks down everything you need to know about capital gains tax on selling second property, how to calculate what you owe, and—most importantly—legitimate ways for avoiding capital gains tax on a second property where possible.
What Is Capital Gains Tax on a Second Property?
Capital Gains Tax (CGT) is the tax on profits realised from the sale (or ‘disposal of’) of an asset that may have gone up in value. The income earned, rather than the total amount of money received, is subject to the tax. For example, if you bought a holiday home for £200,000 and sold it years later for £350,000, your ‘gain’ is £150,000.
If you have a house that you purchased as a second home, the rules for capital gains tax are quite different from those you have for your main residence. The “Private Residence Relief” (PRR) rules mean that, in general, CGT is not taxable when you sell your main home. Any other type of property—such as a buy-to-let, a holiday home or property that you’ve inherited—is typically liable to CGT.
The government will continue to see property gains as a major source of revenue for 2026/27. The first part of your duty to making sure you don’t end up with an unwelcome shock from HMRC after you’ve given the keys is understanding how much capital gains tax is due on a second home.
How Much Is Capital Gains Tax on a Second Property? (2026/27 rates)
The amount of tax you pay depends on two main factors: your total taxable income and the size of the gain itself. Residential property is taxed at higher rates than other assets (like stocks and shares).
| Detail | 2026/27 |
|---|---|
| Basic-rate taxpayer (income + gain within basic-rate band) | 18% |
| Higher/additional-rate taxpayer (income + gain over basic-rate threshold) | 24% |
| Annual Exempt Amount (tax-free allowance, per person) | £3,000 |
| Business Asset Disposal Relief (qualifying gains, up to £1m lifetime) | 18% |
| Reporting and payment deadline | 60 days from completion |
For the 2026/27 period, the rates are generally structured as follows:
- Basic Rate Taxpayers: If your total income plus your capital gain falls within the basic rate tax band, you will typically pay 18% on your property gains.
- Higher or Additional Rate Taxpayers: If your income exceeds the basic rate threshold, you will pay 24% on your property gains.
The Annual Exempt Amount has been significantly reduced in recent years, from £12,300 in 2022/23 down to £3,000 for 2026/27, meaning almost every profitable sale of a second home will result in some tax liability. This allowance cannot be carried forward and is lost if unused in a given tax year.
Worked example: A basic-rate taxpayer with £35,000 income sells a second property for a £25,000 gain. After the £3,000 allowance, £22,000 is taxable. Roughly £15,270 sits within the remaining basic-rate band and is taxed at 18% (£2,748.60), with the remaining £6,730 taxed at 24% (£1,615.20), giving a total CGT bill of approximately £4,363.80.
When calculating how much is capital gains tax on a second property, you don’t just look at the sale price. You are allowed to deduct certain costs to reduce your taxable gain, such as:
- Estate agent fees and solicitor fees from both the purchase and the sale.
- Stamp Duty Land Tax paid when you originally bought the property.
- Costs of “capital improvements,” such as an extension or a new conservatory (general maintenance like painting or fixing a leak does not count).
The 60-Day Reporting Deadline
One of the most critical aspects of selling a second home is the 60-day reporting and payment deadline. In years past, you could wait until your annual Self-Assessment tax return to report property gains. Those days are gone.
If you sell a UK residential property and have CGT to pay, you must:
- Report the gain to HMRC via a “Capital Gains Tax on UK Property” account.
- Pay the tax due.
Both of these actions must be completed within 60 days of the completion date of the sale. Failure to do so results in an automatic £100 penalty even where no tax is owed, with further penalties and daily interest charges building the longer the return is outstanding.

How to Avoid or Reduce Capital Gains Tax on a Second Property
While you must always pay what is legally owed, there are several strategic ways for avoiding capital gains tax on a second property or, at the very least, significantly reducing the bill.
1. Private Residence Relief (PRR) “Flipping”
If you have lived in the second property at any point as your main home, you may be entitled to PRR for the period you resided there, plus the final 9 months of ownership (even if you weren’t living there during those 9 months). By “nominating” a property as your primary residence for a period, you can reduce the proportion of the gain that is taxable.
2. Spousal Transfers
If you are married or in a civil partnership, you can transfer assets between each other “at no gain, no loss.” This allows you to use two sets of Annual Exempt Amounts, effectively £6,000 combined. Furthermore, if one partner is in a lower tax bracket (basic rate), transferring a portion of the property to them before the sale could see that portion of the gain taxed at 18% instead of 24%.
3. Offsetting Losses
If you have sold another asset at a loss—such as shares or even another property—you can “offset” that loss against your gain. This is a vital strategy for how to avoid capital gains tax on a second property legally. Losses can even be carried forward from previous tax years if they were reported to HMRC at the time.
4. Pension Contributions
Increasing your pension contributions in the year you sell a property can lower your overall taxable income. In some cases, this might pull you down from the higher-rate tax band into the basic-rate band, potentially reducing your CGT rate from 24% to 18%.
5. Business Asset Disposal Relief (BADR)
If the property formed part of a qualifying business disposal (rather than a standard second home or buy-to-let), BADR can reduce the CGT rate to 18% on up to £1 million of lifetime gains, up from 14% in 2025/26. This relief generally does not apply to standard second homes or ordinary buy-to-lets, but is worth checking where a property was used in connection with a trading business.
Selling an Inherited Property
Selling an inherited property carries its own set of rules. Usually, the “cost” of the property for CGT purposes is its market value at the date of the person’s death (the probate value).
If you sell the property shortly after inheriting it for the same value as the probate valuation, there may be no CGT to pay. However, if the property sits in your name for several years and increases in value before you sell it, you will owe Capital Gains Tax on Second Property on the increase in value from the date of death to the date of sale.
Second Home vs Buy-to-Let vs Holiday Let — Does It Change Anything?
The type of property you own can influence your tax position:
- Standard Second Homes: Used for personal use; these are fully liable for CGT.
- Buy-to-Let (BTL): These are treated as investments. You can deduct costs, but the gains are taxed at the standard 18%/24% residential rates. Mortgage interest on BTL income is also restricted under Section 24 rules, though this affects income tax rather than CGT directly.
- Furnished Holiday Lets (FHLs): The FHL regime was fully abolished from 6 April 2025. From the 2025/26 tax year onward, holiday lets are taxed as standard residential property with no special capital allowances, no automatic BADR eligibility, and mortgage interest restricted the same way as other buy-to-lets. If you sell a former FHL property in 2026/27, it is taxed under the same 18%/24% rules as any other second home unless it separately qualifies as part of a genuine trading business disposal.
Common Mistakes People Make
Even with the best intentions, many taxpayers fall into traps when dealing with capital gains tax on selling second property:
- Missing the 60-day window: This is the most common error, leading to automatic fines.
- Incomplete Records: Not keeping receipts for capital improvements made 10 or 15 years ago means you cannot deduct those costs from your gain.
- Incorrect Valuation: For inherited properties or properties gifted to children, using an “estimated” value rather than a professional valuation can lead to HMRC investigations.
- Forgetting the Legal Fees: Many people forget to add their solicitor’s fees and land registry charges to the purchase price, which increases the “gain” unnecessarily.

FAQs: Frequently Asked Questions
Do I pay CGT if I’ve never lived in the second property?
Yes. In fact, if you have never lived in it, you generally won’t be eligible for any Private Residence Relief, meaning the entire gain (minus your annual allowance and costs) will be taxable.
Can I avoid CGT entirely by gifting the property to my children?
No. Gifting a property to someone other than a spouse is treated as a “disposal” at market value. HMRC will calculate the tax based on what you would have made if you had sold it at a fair price on the open market.
What if I sell the property at a loss?
If you sell at a loss, you don’t pay CGT. More importantly, you should report this loss to HMRC, as it can be used to offset future gains on other assets.
Do married couples or civil partners get double the tax-free allowance?
If the property is held in joint names, both individuals can apply their Annual Exempt Amount to the gain, effectively doubling the tax-free portion of the sale.
Is CGT different if I’m a UK non-resident selling a UK property?
Yes. Non-residents are also liable for CGT on UK residential property and must also follow the strict reporting and payment deadlines, though the calculation of the gain may differ based on when the property was acquired
Conclusion
Managing Capital Gains Tax on Second Property in 2026/27 requires a proactive approach. The time frame of 60 days is expiring on all completions, and no time should be lost. Knowing the rates, maintaining accurate records of capital improvements, and taking advantage of reliefs such as spousal transfers and loss offsetting will help to preserve your investment and ensure you are not paying more than you have to.
Property remains a powerful asset, but the “tax tail” can often wag the “investment dog.” Stay informed, plan ahead, and if your financial situation feels complex, don’t hesitate to seek professional advice to navigate the path ahead.
