What are the current CGT rates on residential property sales in the UK for the 2024/2025 tax year, and how do I report and pay CGT to HMRC within the 60-day deadline, including if I'm not self-employed?
Quick Answer
In the 2024/2025 tax year, residential property CGT rates are 18% for basic rate and 24% for higher/additional rate taxpayers, with a £3,000 annual exemption.
## Understanding Capital Gains Tax on UK Residential Property Sales
Navigating Capital Gains Tax (CGT) when selling a residential property is critical for any UK property investor. It's not just about the rates, but also understanding the reporting and payment obligations. Failing to meet deadlines can lead to penalties, so getting it right from the start is paramount.
* **Current CGT Rates (2024/2025 Tax Year):** As of December 2025, if you're a basic rate taxpayer, any capital gains from residential property are taxed at **18%**. If you fall into the higher or additional rate tax bracket, your gains are taxed at **24%**. This applies to gains made on properties that are not your main home.
* **Annual Exempt Amount:** For the 2024/2025 tax year, everyone gets an annual exempt amount of **£3,000**. This means you don't pay CGT on the first £3,000 of your total residential property gains in a tax year. This threshold was reduced from £6,000 in April 2024.
* **Determining Your Tax Rate:** Your CGT rate depends on your total taxable income, including your salary, rental income, and any other income, combined with your capital gain. If, after adding your gain (minus the £3,000 exemption) to your income, you remain a basic rate taxpayer, your CGT will be 18%. If you cross into the higher or additional rate bands, that portion of your gain will be taxed at 24%. It's worth noting that if you have significant rental income, due to Section 24, your income tax burden might push you into a higher band faster.
* **Calculating the Gain:** The taxable gain is essentially the sale price minus the original purchase price and allowable costs. Allowable costs include Stamp Duty Land Tax (SDLT), which for an additional dwelling is 5% on top of the standard rates, legal fees for both buying and selling, and costs of significant improvements (not repairs) to the property. For example, if you bought a second property for £200,000 and incurred £10,000 in SDLT (assuming this was part of the 5% surcharge on an additional dwelling) and legal fees, and then spent £20,000 on an extension, your cost base would be £230,000. If you later sold it for £300,000, your gross gain would be £70,000. After the £3,000 annual exemption, your taxable gain would be £67,000. At a 24% tax rate, this would mean a CGT bill of £16,080.
## Potential Pitfalls and Reporting Challenges
While the rates seem straightforward, understanding the rules and meeting deadlines is where many investors can go wrong. Reporting and paying CGT on residential property within 60 days of completion is a strict requirement.
* **The 60-Day Deadline:** This is perhaps the most critical deadline. You have just 60 calendar days from the completion date of the sale to report the gain and pay the estimated CGT to HMRC. Missing this deadline can lead to initial late filing penalties, followed by daily penalties if payment is further delayed.
* **Who Needs to Report?:** Anyone who sells UK residential property and makes a capital gain, or even a loss, needs to report this within the 60-day window. This applies if the property was not your main home. It impacts individual landlords, regardless of whether they are self-employed or not. HMRC expects everyone to comply, even if this is your only property transaction for the year. This contrasts with Corporation Tax, which has different reporting and payment schedules for companies owning property.
* **How to Report and Pay:** You must use HMRC's 'UK property tax' online service to report the gain and pay the tax. This is separate from your annual Self Assessment tax return. You'll need to create a Government Gateway account if you don't already have one. The system will guide you through calculating your gain and the tax due, and then allow you to pay online. Even if you're not self-employed and don't usually do a tax return, this obligation still applies.
* **Estimating the Tax:** You need to estimate your income for the tax year to determine if you're a basic, higher, or additional rate taxpayer to calculate the correct CGT. It's an estimate, as your final income might not be known until the end of the tax year. However, you must make a reasonable estimate at the time of reporting.
* **Underestimating and Reconciliation:** If you underestimate your tax due when reporting after 60 days, you might have to pay interest on the underpayment. The exact CGT liable will be reconciled when you submit your annual Self Assessment tax return for that tax year. Any overpayment or underpayment will be adjusted then.
## Investor Rule of Thumb
Always factor in Capital Gains Tax from the outset; it's a significant cost that directly impacts your net profit, and ignoring the 60-day reporting window will undoubtedly lead to penalties.
## What This Means For You
Understanding CGT rates and the specific 60-day reporting requirement is essential for responsible property investment. Many investors get caught out by these deadlines, especially if they are not used to filing tax returns.

Steven's Take
Selling a property is often seen as the finish line, but for tax purposes, it's a new starting gun. The 60-day CGT reporting rule for residential property is not optional, and HMRC is serious about it. I've seen too many landlords caught out because they assume their accountant will handle it automatically, or that it only applies to those operating as a business. It doesn't. If you're selling a property that isn't your own home, you need to be proactive and engage with the HMRC online service. Getting this wrong can eat into your profits with unnecessary penalties.
What You Can Do Next
Calculate your residential property gain: Deduct your original purchase price, costs of purchase (like SDLT and legal fees), and significant improvement costs from your sale price.
Determine your CGT rate: Estimate your total taxable income for the tax year to see if you'll be a basic, higher, or additional rate taxpayer.
Utilise the annual exempt amount: Deduct the £3,000 annual exempt amount from your total taxable gain for the 2024/2025 tax year.
Report and pay within 60 days: Use HMRC's 'UK property tax' online service to report your gain and pay your estimated CGT within 60 days of the sale completion.
Reconcile via Self Assessment: Include the reported gain in your next Self Assessment tax return for final reconciliation with HMRC.
