Gifting Shares to Family Members: Capital Gains Tax, Holdover Relief and Family...
Inheritance tax is often misunderstood until families are faced with a large tax bill after a death or a poorly planned lifetime gift. Many individuals assume that giving assets away automatically removes them from their estate, but UK inheritance tax rules are significantly more complex.
The timing of gifts, the type of asset transferred, and even the loss in value to the donor’s estate can all affect the final inheritance tax position. Without careful planning, well-intentioned gifting strategies can create unexpected tax exposure for families and business owners.
Inheritance tax (IHT) is generally charged on the value of a person’s estate at death, including certain gifts made during their lifetime. In the UK, gifts to individuals are usually treated as Potentially Exempt Transfers (PETs) and become exempt if the donor survives seven years, while gifts to trusts or companies may trigger an immediate inheritance tax charge as Chargeable Lifetime Transfers (CLTs).
Understanding how HMRC values assets, applies the seven-year rule, and calculates the reduction in a donor’s estate is essential for effective inheritance tax planning.
Inheritance tax is a UK tax charged primarily on the transfer of wealth. It is governed mainly by the Inheritance Tax Act 1984 and applies to estates, lifetime gifts, trusts, and certain transfers of business or investment assets.
Broadly, inheritance tax is charged on the net value of a person’s estate, meaning:
Assets are generally valued at their open market value at the date of death or transfer. HMRC defines this as the price the asset might reasonably achieve if sold on the open market at that time.
For most estates, the standard inheritance tax rate is:
Transfer Type | IHT Rate |
Chargeable Lifetime Transfers (CLTs) | 20% |
Death Estate / Failed PETs | 40% |
The nil-rate band currently remains at £325,000 for most individuals, although additional reliefs and allowances may apply depending on circumstances.
One of the most important inheritance tax concepts is frequently overlooked:
Inheritance tax does not simply tax the asset transferred. Instead, it taxes the reduction in the value of the donor’s estate caused by the transfer.
This distinction is critical.
For inheritance tax purposes, HMRC often focuses on the economic loss suffered by the donor’s estate rather than solely the standalone value of the gifted asset.
This principle becomes particularly important where:

Most gifts made by one individual to another individual are treated as Potentially Exempt Transfers (PETs).
A PET is not immediately chargeable to inheritance tax. Instead, the gift becomes exempt if the donor survives for seven years from the date of the transfer.
Common examples include:
However, if the donor dies within seven years, the PET becomes a failed PET and is brought back into the inheritance tax calculation.
This is commonly referred to as the “seven-year rule”.
Importantly, HMRC reviews the reduction in the donor’s estate caused by the gift, not merely the market value of the gifted item in isolation.
Not all lifetime gifts qualify as PETs.
Transfers into trusts, certain company structures, or other non-individual recipients can create Chargeable Lifetime Transfers (CLTs), which may trigger an immediate inheritance tax charge.
Where a CLT exceeds the available nil-rate band, inheritance tax is generally payable at 20% during lifetime.
The available nil-rate band is reduced by earlier CLTs made within the previous seven years.
This creates an important planning point: inheritance tax exposure cannot be assessed by reviewing a single transaction in isolation. Historic transfers must also be considered.
If the donor dies within seven years of making the CLT, further inheritance tax may become payable at death rates, although credit is usually given for any lifetime tax already paid.
Consider a simplified example involving valuable antique furniture.
An individual owns a complete collection worth £200,000. One item from the collection, when separated, has a standalone value of only £25,000. However, removing it causes the remaining collection to lose substantial value.
The individual gifts that single item to a child.
For capital gains tax purposes, the transfer may initially appear relatively modest because CGT generally focuses on the value of the asset transferred.
For inheritance tax purposes, however, HMRC examines the reduction in the donor’s estate caused by the gift. If removing that item reduces the overall estate value by £150,000, inheritance tax may ultimately apply to the larger economic reduction rather than the isolated asset value.
This illustrates why inheritance tax planning must never be approached purely from a capital gains tax perspective.
A transaction that appears efficient for CGT may still create significant inheritance tax exposure if the donor dies within seven years.
This principle is especially relevant for owners of family businesses and investment companies.
Many shareholders underestimate how dramatically share values can change when control is diluted.
For example:
As a result, inheritance tax may apply based on the reduction in the value of the donor’s estate, not simply the market value of the shares gifted.
This can become particularly problematic for:
Unlike qualifying trading businesses, investment companies often do not benefit from Business Property Relief, meaning shareholdings may remain fully exposed to inheritance tax.
Business owners should therefore exercise caution before transferring minority stakes, especially where control thresholds are affected.
Inheritance tax planning should never occur in isolation from capital gains tax planning.
Many lifetime gifts create immediate capital gains tax consequences because assets are treated as disposed of at market value for CGT purposes.
This commonly affects:
In practice, effective tax planning requires balancing:
A strategy focused purely on reducing inheritance tax can often create unintended CGT costs or commercial risks.
Practical Inheritance Tax Planning Considerations
From a tax adviser’s perspective, inheritance tax planning is rarely about making isolated gifts shortly before death. Effective planning is usually long term, structured, and coordinated with wider family, business, and succession objectives.
Some of the most common mistakes include:
For business owners and high-net-worth individuals, professional valuation advice and detailed tax modelling are often essential before transferring significant assets.
Careful planning can substantially reduce inheritance tax exposure, but poorly structured transfers can create avoidable tax liabilities and family disputes.
Inheritance tax planning involves far more than simply giving assets away. HMRC examines the economic reduction in a donor’s estate, the nature of the transfer, the timing of gifts, and the interaction between inheritance tax and capital gains tax rules.
Understanding the distinction between PETs and CLTs, the seven-year rule, and how asset valuations operate is critical for individuals looking to protect family wealth and minimise unnecessary tax exposure.
For business owners, landlords, and individuals with valuable estates, inheritance tax planning should be approached strategically and reviewed regularly as circumstances change.
Inheritance tax planning requires careful analysis, technical expertise, and commercially practical advice. Whether you are considering gifting assets, restructuring family shareholdings, or reviewing your estate planning strategy, obtaining professional guidance early can make a substantial difference.

Inheritance tax planning is the process of legally arranging your assets and affairs to reduce potential inheritance tax liabilities. In the UK, inheritance tax is generally charged at 40% on estates exceeding available thresholds and reliefs. Effective inheritance tax planning can help preserve family wealth, reduce tax exposure, improve succession planning, and avoid unnecessary HMRC disputes or delays during estate administration.
Inheritance tax planning often involves making lifetime gifts that may fall outside your estate after seven years. Gifts to individuals are usually treated as Potentially Exempt Transfers (PETs). If the donor survives seven years from the date of the gift, the transfer generally becomes exempt from inheritance tax. If the donor dies within seven years, the gift may become chargeable and increase the estate’s inheritance tax liability.
Inheritance tax planning should ideally start as early as possible rather than later in life. Early planning provides more flexibility around gifting, trusts, business restructuring, and estate protection strategies. Leaving inheritance tax planning too late can reduce available options, increase compliance risks, and limit the effectiveness of seven-year gifting strategies or business relief opportunities.
Yes, lifetime gifting can reduce inheritance tax exposure, but it must be structured carefully. While many gifts qualify as PETs, they may still create capital gains tax consequences or fail if the donor dies within seven years. HMRC also considers the reduction in the donor’s estate value, especially for business shares or connected assets. Proper tax advice is essential before transferring significant wealth.
Yes, professional advice is strongly recommended for inheritance tax planning involving family companies or investment businesses. Share transfers can trigger complex valuation issues, particularly where control of the company changes. A small transfer may significantly reduce the value of the donor’s remaining shares, increasing inheritance tax exposure. Business Property Relief may also be unavailable for investment companies such as property rental businesses.
Inheritance tax planning is particularly important for landlords because investment properties and buy-to-let companies are often fully exposed to inheritance tax. Unlike qualifying trading businesses, property investment companies generally do not benefit from Business Property Relief. Without proper planning, large property portfolios can create substantial inheritance tax liabilities for beneficiaries and may force asset sales to fund the tax bill.
Without inheritance tax planning, estates exceeding available allowances may face inheritance tax at 40%. The standard nil-rate band is currently £325,000, with additional residence nil-rate band relief potentially available in some circumstances. However, large estates, investment portfolios, and family businesses can quickly exceed these thresholds, especially where reliefs are unavailable or lifetime gifts fail within seven years.
Yes, trusts are commonly used in inheritance tax planning, but they carry specific tax rules and reporting obligations. Transfers into many trusts are treated as Chargeable Lifetime Transfers (CLTs) and may trigger an immediate 20% inheritance tax charge above the available nil-rate band. Trusts can still be highly effective for asset protection and succession planning when structured correctly with professional advice.
Common inheritance tax planning mistakes include making gifts without understanding the seven-year rule, ignoring capital gains tax exposure, assuming all business shares qualify for Business Property Relief, and failing to document gifts properly. Many individuals also underestimate HMRC’s valuation rules for connected assets and family company shares. Poorly structured planning can create unexpected tax liabilities and family disputes.
Yes, effective inheritance tax planning can significantly improve long-term family wealth preservation. Structured planning may reduce inheritance tax liabilities, improve asset protection, support succession planning, and provide greater certainty for beneficiaries. Strategies may include lifetime gifting, trusts, business restructuring, wills, and tax-efficient ownership arrangements tailored to the family’s financial and commercial objectives.
