Selling a second home in the UK can be a lucrative decision, especially with rising property prices. However, many sellers are blindsided by the complex tax obligations that come with such transactions. HM Revenue & Customs (HMRC) has been tightening its grip on property sales, and a shocking number of sellers — as many as 90% — overlook critical rules that could lead to hefty penalties, unexpected tax bills, or even legal trouble.This article explores the often-overlooked compliance risks associated with selling a second home, the consequences of failing to meet HMRC’s requirements, and how to navigate these challenges effectively. Whether you’re selling a buy-to-let property, a holiday home, or an inherited house, understanding these rules is essential to avoid costly mistakes.
The Overlooked Rule: Reporting Capital Gains Tax (CGT) Within 60 Days
One of the most significant changes in recent years is HMRC’s requirement to report and pay any Capital Gains Tax (CGT) on the sale of a second home within 60 days of completion. This rule, introduced in April 2020, replaced the previous system where sellers could wait until the end of the tax year to report gains.Shockingly, many sellers remain unaware of this deadline, leading to automatic penalties for late reporting. According to HMRC, thousands of property owners have already been fined for missing the 60-day window.
Why Do Sellers Miss This Rule?
- Lack of Awareness: Many sellers assume they can report property sales during their annual self-assessment, as was the case before 2020.
- Miscommunication with Solicitors: Solicitors handling property transactions often focus on legal aspects and fail to inform clients about their tax obligations.
- Complex Calculations: Determining the taxable gain on a property sale can be complicated, especially when factoring in allowable expenses, reliefs, and exemptions.
The Consequences of Missing the Deadline
Failing to report CGT within 60 days results in automatic penalties:
- £100 fine for missing the initial deadline.
- Additional penalties of £10 per day after three months, up to a maximum of £900.
- After six months, further penalties of 5% of the unpaid tax or £300, whichever is greater.
For example, if you sell a second home with a taxable gain of £100,000 and fail to report it for six months, you could face penalties exceeding £5,000 — a costly oversight for something that could have been avoided with proper planning.
Capital Gains Tax: The Basics
When selling a second home, any profit made on the sale is subject to CGT. The tax is calculated on the difference between the property’s sale price and its original purchase price, minus allowable expenses and reliefs.
CGT Rates for Residential Property
- 18% for basic-rate taxpayers.
- 28% for higher- and additional-rate taxpayers.
For example, if you’re a higher-rate taxpayer and sell a second home with a gain of £150,000, you could face a CGT bill of up to £42,000.
Allowable Deductions
To reduce your CGT liability, you can deduct certain costs, including:
- Stamp Duty Land Tax (SDLT) paid at the time of purchase.
- Estate agent and solicitor fees.
- Costs of improvements (e.g., extensions or renovations).
However, routine maintenance costs, such as repainting or repairs, are not deductible.
The HMRC Crackdown on Second Home Sales
HMRC has significantly increased its scrutiny of second home sales in recent years. Using advanced data analytics and information-sharing agreements, the tax authority can now identify unreported property transactions with ease.
How HMRC Tracks Property Sales
- Land Registry Data: HMRC cross-references property sales recorded with the Land Registry against self-assessment tax returns.
- Stamp Duty Records: When you purchase a second home, you pay an additional 3% SDLT surcharge. HMRC uses this data to flag potential second home sales.
- Nudge Letters: HMRC has been sending “nudge letters” to individuals suspected of failing to report property sales, urging them to review their tax affairs,.
The Risks of Non-Compliance
Failing to report a second home sale or underpaying CGT can result in:
- Backdated Tax Bills: HMRC can investigate property sales going back up to 20 years in cases of deliberate non-compliance.
- Penalties: These can range from 30% to 100% of the unpaid tax, depending on the severity of the offence.
- Criminal Prosecution: In extreme cases, HMRC may pursue legal action against individuals who deliberately evade taxes.
The Overlooked Reliefs That Could Save You Thousands
While many sellers focus on the tax they owe, few take full advantage of the reliefs available to reduce their CGT liability.
1. Private Residence Relief (PRR)
If the property was your main home for part of the ownership period, you may qualify for PRR. This relief exempts the portion of the gain attributable to the time you lived in the property, plus the final nine months of ownership.For example, if you owned a property for 10 years and lived in it for 5, PRR could exempt 50% of the gain.
2. Lettings Relief
Lettings relief applies if you rented out a property that was once your main home. While the rules have been tightened, you can still claim up to £40,000 in relief if you shared occupancy with tenants.
3. Spousal Transfers
Transferring ownership of the property to a spouse or civil partner before the sale can double your CGT allowance (£6,000 per person in 2024–2025). This strategy is particularly effective if your partner is in a lower tax bracket.
4. Loss Offsetting
If you’ve made losses on other investments, such as shares or another property, you can offset these against your gains to reduce your CGT bill.
The Role of Professional Advice
Given the complexity of CGT rules, seeking professional advice is essential to ensure compliance and minimise your tax liability. A qualified tax advisor can help you:
- Calculate your taxable gain accurately.
- Identify and claim all available reliefs.
- Ensure you meet the 60-day reporting deadline.
Why Local Expertise Matters
When searching for a tax advisor, proximity can be an advantage. A tax advisor near you will have a deeper understanding of local property markets and regional tax nuances, enabling them to provide tailored advice. For example, a tax advisor familiar with London’s property market may be better equipped to handle cases involving high-value homes or overseas buyers.
Case Study: The Cost of Overlooking the 60-Day Rule
A landlord in Manchester sold a buy-to-let property in 2023, realising a gain of £120,000. Unaware of the 60-day reporting rule, they waited until the end of the tax year to include the sale in their self-assessment return.By the time they filed, HMRC had already issued penalties:
- £100 for missing the initial deadline.
- £900 for being three months late (£10 per day).
- £6,000 (5% of the unpaid tax) after six months.
In total, the landlord faced £7,000 in penalties, on top of their £33,600 CGT bill. Had they sought professional advice, they could have avoided these fines and potentially reduced their tax liability through reliefs.

To avoid falling foul of HMRC’s rules, follow these steps:
