I'm considering selling a property I inherited a few years ago. What's the capital gains tax base cost for inherited property in the UK, and how does it affect my liability?
Quick Answer
The CGT base cost for inherited property is its market value on the date of death, not the original purchase price. This is crucial for calculating gains, with rates at 18% or 24% and a £3,000 annual exempt amount.
## Understanding the Capital Gains Tax (CGT) Base Cost for Inherited Property
For inherited property in the UK, the Capital Gains Tax (CGT) base cost is, by default, its market value on the date of the deceased's death, not the original purchase price. This valuation forms the starting point for calculating any capital gain when you eventually sell the property. This rule is set out by HMRC and is a critical factor for anyone inheriting property to understand, as it directly impacts their potential tax liability.
The annual exempt amount for CGT is £3,000 for the 2025/26 tax year, reduced from previous years. Basic rate taxpayers pay 18% CGT on residential property gains above this threshold, while higher and additional rate taxpayers incur 24%. It's important to ascertain the market value accurately at the date of death; often, the valuation used for probate purposes is accepted by HMRC. This can involve obtaining a professional valuation, which might be an allowable expense against the gain.
### How is the market value at the date of death determined?
The market value at the date of death is typically established through one or more professional valuations. This valuation must reflect what the property would reasonably fetch on the open market at that specific time. For properties requiring probate, a valuation is usually obtained as part of the probate process and often accepted by HMRC. If no formal valuation was conducted at the time, you may need to commission a retrospective valuation from a RICS surveyor. Keeping records of this valuation is vital for future CGT calculations.
## Impact on Investor Costs and Returns
The base cost rule significantly impacts an investor's potential CGT liability and overall net return. A higher base cost (market value at death) reduces the capital gain, leading to a lower tax bill. Conversely, if the property's value has not appreciated significantly since the date of death, or has even fallen, the CGT liability will be minimal or non-existent.
For example, if a property was valued at £300,000 at the date of death, and you sell it for £353,000, your gross gain is £53,000. After deducting the £3,000 annual exempt amount, the taxable gain is £50,000. A higher rate taxpayer would pay 24% of this, equating to £12,000 in CGT. If the original purchase price was £100,000 and that was incorrectly used as the base cost, the perceived gain would be £253,000, with a much larger tax consequence. This highlights the importance of using the correct, higher base cost.
### Scenario 1: Recent Inheritance, Low Appreciation
Consider an investor who inherited a property valued at £250,000 at death and sells it a few years later for £260,000. After deducting £3,000 annual exempt amount, the taxable gain is £7,000. A higher rate taxpayer would pay 24% of this, or £1,680. The accurate base cost minimises the tax, demonstrating how the rule can reduce the CGT burden on properties that haven't seen substantial appreciation post-inheritance. Understanding your potential CGT liability early can influence your sale strategy, particularly regarding *exit strategy and tax planning*.
### Scenario 2: Longer-Held Inheritance, Significant Appreciation
An investor inherited a property valued at £150,000 at death five years ago and sells it for £300,000 today. The gross gain is £150,000. After the £3,000 exempt amount, the taxable gain is £147,000. A higher rate taxpayer would pay 24%, totaling £35,280 in CGT. Even with the advantageous base cost rule, substantial property price growth will lead to a considerable tax bill, underscoring the need for *capital gains tax planning*.
## Allowable Expenses to Reduce CGT
Several expenses can be deducted from the calculated gain to further reduce your CGT liability. These include costs incurred in acquiring and disposing of the property. Common deductions include solicitor's fees, estate agent's fees, and valuation fees for probate or sale. Some improvement works, such as building an extension, can also be allowable if they add value to the property, but routine maintenance like repainting is generally not. Retain all receipts and invoices. For inherited properties, the Stamp Duty Land Tax (SDLT) paid by the deceased is not usually an allowable expense for your CGT calculation, but any SDLT you paid upon transferring ownership would be relevant.
## Investor Rule of Thumb
Always ensure the base cost for inherited property aligns with the market value at the date of death, and diligently retain all probate and valuation documents to minimise your Capital Gains Tax liability.
## What This Means For You
Getting the base cost right for inherited property is fundamental to accurate CGT calculation. It is not about avoiding tax, but paying only what is legitimately due. For investors, understanding these nuances is crucial for *optimising investment returns* and ensuring compliance.

Steven's Take
Inheriting property usually comes with a degree of emotional baggage, so tax can often be an afterthought. However, when it comes to Capital Gains Tax, establishing the correct base cost is arguably the most important step. Don't just assume the original purchase price. Get a retrospective valuation if you need to, and ensure all your allowable expenses are meticulously recorded. This proactive approach will save you thousands down the line.
What You Can Do Next
1. Obtain proof of market value at date of death: Refer to the probate valuation documents. If none exists, commission a retrospective valuation from a RICS-qualified surveyor.
2. Identify all allowable expenses: Gather records for solicitor's fees, estate agent fees, and significant improvement works (not repairs) that increased the property's value.
3. Calculate your potential Capital Gains Tax: Use the HMRC guidance on gov.uk/capital-gains-tax-property to estimate your liability, factoring in the £3,000 annual exempt amount.
4. Consult a property tax specialist: Engage a qualified accountant or tax advisor experienced in property (search 'property tax accountant' on ICAEW.com) to review your specific situation and ensure all deductions are claimed correctly before selling.
