Inherited Property Tax Guide
Selling an inherited property to a family member - what you need to know
Selling an inherited property to a sibling, child, or other family member might seem like the simplest option. However, HMRC treats sales between family members differently from regular property transactions, and the tax consequences can be significant if you do not understand the rules.
This guide explains the connected persons rules, capital gains tax implications, inheritance tax risks, and what to consider before selling an inherited property to a family member in the UK.

HMRC Connected Persons Rules
How HMRC treats property sales between family members
HMRC has specific rules for transactions between connected persons. Understanding these rules is essential before selling an inherited property to a relative.
Who counts as a connected person
Connected persons include your spouse or civil partner, your siblings (including half-siblings), your parents, your children, your grandparents, your grandchildren, and the spouses or civil partners of all of these people. Business partners and their families also qualify. The full list is set out in sections 286 and 287 of the Taxation of Chargeable Gains Act 1992. If the buyer is on this list, the connected persons rules apply to the sale.
Market value is substituted
When you sell a property to a connected person, HMRC substitutes the market value of the property for the actual sale price when calculating capital gains tax. This applies regardless of the price you agree with the family member. Even if you sell at a genuine discount to help a sibling or child, CGT is calculated as though you sold at full market value. This is the single most important rule to understand.
The sale must still be at arm's length
Even though HMRC substitutes market value for CGT purposes, the actual price agreed between the parties matters for other purposes. If you sell significantly below market value, the difference is treated as a gift with potential IHT consequences. It is also important to obtain a professional independent valuation so both parties can demonstrate the market value to HMRC if questioned.
Independent valuation is essential
Both the seller and the buyer should obtain an independent RICS valuation of the property. This establishes the market value that HMRC will use for CGT calculations. It also protects both parties if HMRC queries the transaction. Without a professional valuation, HMRC may substitute their own assessment of market value, which could result in a higher tax bill than expected.
Legal advice is strongly recommended
Selling an inherited property to a family member involves overlapping tax rules for CGT, IHT, and stamp duty. The interaction between these taxes can be complex, and mistakes can be costly. Both parties should seek independent legal and tax advice before proceeding. A solicitor experienced in connected persons transactions can help structure the sale to minimise tax exposure while remaining fully compliant with HMRC rules.
Consider the impact on other beneficiaries
If the property was left to multiple beneficiaries but one wants to buy out the others, this changes the dynamics. The buying beneficiary needs to pay the other beneficiaries their share of the market value. If the price is below market value, the other beneficiaries are effectively making a gift of the difference. This can create tension within the family and has its own tax implications for each person involved.
Tax Implications
The tax consequences of selling inherited property to family
There are three main taxes to consider when selling an inherited property to a family member. Getting any of these wrong can result in an unexpected tax bill.
Capital gains tax (CGT)
CGT is calculated on the difference between the probate value (your base cost) and the current market value of the property. For connected persons, the actual sale price is irrelevant for CGT. Residential property CGT rates are 18 percent for basic rate taxpayers and 24 percent for higher rate taxpayers. The annual CGT allowance is currently 3,000 pounds per person. If the property has increased in value since the date of death, you will have a taxable gain.
Inheritance tax (IHT)
If you sell below market value, the difference between the sale price and the market value is treated as a gift for IHT purposes. This is classified as a potentially exempt transfer (PET). If you survive seven years, the gift becomes exempt. If you die within seven years, the gift value is added to your estate. Taper relief may reduce the IHT on gifts made between three and seven years before death. The current IHT nil rate band is 325,000 pounds.
Stamp duty land tax (SDLT)
The buyer (your family member) will need to pay stamp duty. For connected persons transactions that are not at arm's length, HMRC may assess stamp duty on the market value rather than the price paid. If the property is an additional home for the buyer, the additional dwelling surcharge of 5 percent also applies. The buyer should budget for stamp duty as part of the purchase costs and take advice on whether market value or the actual price applies in their specific situation.
The Alternative
Why selling to a cash buyer can be simpler than selling to family
For many families, selling to an independent cash buyer avoids the tax complexity and family tension that comes with selling to a relative.
CGT based on actual sale price
When you sell to an independent buyer at arm's length, CGT is calculated on the actual sale price rather than a deemed market value. This means there is no risk of paying tax on money you did not receive. The transaction is straightforward and transparent for HMRC purposes.
No IHT gift implications
Because the sale is a genuine commercial transaction, there is no element of gift. This means there are no potentially exempt transfer implications and no seven-year rule to worry about. The full sale proceeds become part of the estate for distribution to all beneficiaries.
Fair distribution among all beneficiaries
When one family member buys the property at a discount, the other beneficiaries may feel shortchanged. Selling to an independent buyer at a fair price means the proceeds can be distributed equally and transparently among all beneficiaries according to the will or intestacy rules.
Fast, certain completion
HouseBought4Cash can complete in as little as 7 to 14 days after probate is granted. There are no mortgage approvals, no chain, and no risk of the sale falling through. The process is simple and the sale is guaranteed*, allowing all beneficiaries to receive their share quickly.
We recognise that every family situation is different. If selling to a family member is genuinely the right choice for your circumstances, we would always encourage you to seek professional tax and legal advice first. But if you want to avoid the complexity and keep things straightforward, selling to an independent cash buyer is often the simplest path forward.
