Business owners face estate planning challenges that are categorically different from those of wealthy individuals whose assets are in investment portfolios and property. A portfolio can be divided, liquidated, or transferred relatively cleanly. A business cannot. It may depend on the owner's relationships, expertise, or time. It may be illiquid — no ready buyer at a fair price in a hurry. It may be the primary source of income for the family both before and after the owner's death.
Estate planning for a business owner must answer two related but distinct questions that are often conflated: Who inherits? (estate planning) and Who runs it? (succession planning). Getting either question wrong can destroy the value that the other question tries to preserve.
The Business as the Primary Asset: Why It Changes Everything
Most estate planning frameworks assume that assets can be valued, divided, and transferred with reasonable certainty. A £5 million investment portfolio can be divided equally among three children. A £5 million family business cannot — at least not without potentially destroying it.
Valuation uncertainty: Unlike a publicly traded company, a private business has no market price. Its value is an estimate derived from earnings multiples, discounted cash flow analysis, comparable transactions, and the specific facts of the business. In a forced sale (an executor needing to liquidate the estate), the realised value may be 30–50% below any "fair" valuation.
Liquidity: Shares in a private limited company cannot be sold quickly without a buyer, a process, and probably a significant discount. An estate that needs to pay IHT within six months of death may need to borrow against the business or sell a stake at a disadvantageous time.
Management dependence: Many owner-managed businesses are heavily dependent on the owner's involvement, relationships, and reputation. The business value assumes the owner is operating it. Without them — or during the uncertainty of a transition — value can erode quickly.
Co-shareholder rights: If the business has other shareholders (partners, co-founders, investors), they have rights too. Share transfers on death may trigger pre-emption rights, tag-along clauses, or other provisions in the shareholders' agreement that constrain what the estate can do.
Business Property Relief: The IHT Exemption for Qualifying Businesses
Business Property Relief (BPR) is one of the most significant IHT reliefs available. It provides either 50% or 100% relief from IHT on qualifying business assets, subject to the April 2026 cap described below.
100% BPR applies (up to a £2.5 million combined BPR/APR cap per estate) to:
- A business or interest in a business (sole trader, partner)
- Shares in an unquoted company (including AIM-listed companies that qualify — see below)
- Shares giving control of a quoted company
Note (from 6 April 2026): The 100% rate is capped at a combined £2.5 million per estate across all BPR and APR assets (the cap was originally announced as £1 million in the October 2024 Budget, then raised to £2.5 million in December 2025, and is transferable between spouses and civil partners — up to around £5 million per couple). Above that threshold, qualifying assets attract 50% relief only (a 20% effective IHT rate). AIM and other unlisted shares attract only 50% relief and do not benefit from the £2.5 million 100% allowance.
50% BPR applies to:
- Land, buildings, or machinery used in a business owned by the transferor
- Shares in a quoted company that do not give control
Qualifying conditions:
- The asset must be a "relevant business property"
- The business must be a trading business (not wholly or mainly an investment business — the distinction is significant for property-holding companies and investment holding companies)
- The asset must have been held for at least two years before the transfer (lifetime gift or death)
The trading vs investment distinction is the most common source of BPR disputes. A company that holds let property, financial investments, or cash beyond what is reasonably required for its trading activities may be classified as an investment company, losing BPR. Mixed businesses (trading with some investment activity) fall on a spectrum, and HMRC applies a "wholly or mainly" test — broadly, if investment activity represents more than 50% of the business by assets, income, or activities, BPR may be denied.
Practical implications:
- A manufacturing company, professional services firm, or technology business typically qualifies for BPR if it has been trading for two years
- A company whose primary activity is holding buy-to-let properties does not qualify
- A cash-rich company where large cash balances are not needed for trading purposes may have part of its value denied BPR (HMRC treats "excepted assets" — cash and investments not needed for trading — as outside BPR)
AIM BPR Shares: A Listed Route to IHT Relief
AIM-listed companies (companies quoted on the London Stock Exchange's Alternative Investment Market) that carry on qualifying trading activities can qualify for BPR after a two-year holding period. However, following the April 2026 BPR reforms, AIM and other unlisted shares now attract only 50% IHT relief (down from 100%) and do not benefit from the £2.5 million 100% allowance at all. For directly held qualifying business and agricultural property, the full 100% rate is capped at a combined £2.5 million per estate across all BPR/APR assets (originally announced as £1 million in the October 2024 Budget, then raised to £2.5 million in December 2025, and transferable between spouses and civil partners), with the excess qualifying for 50% relief only. This significantly changes the IHT arithmetic for larger AIM portfolios.
This has given rise to a well-established wealth management product: AIM BPR portfolios — managed discretionary portfolios of AIM-listed companies selected to qualify for BPR. These are offered by a number of UK wealth management firms.
Why AIM BPR portfolios are used: They offer a route to IHT relief without the illiquidity of a direct business interest. AIM shares can be sold, and the portfolio can be managed actively. The two-year qualifying period is much shorter than the seven years required for a potentially exempt transfer to escape IHT.
Why AIM BPR portfolios require caution: AIM companies are typically smaller, less liquid, and higher risk than main market companies. The IHT benefit is real — but it should not be the primary reason to hold a portfolio of small-cap equities. Investment quality matters. A portfolio selected purely for BPR qualification that subsequently falls 40% in value has provided no net IHT benefit.
HMRC scrutiny: HMRC periodically reviews whether specific AIM companies continue to qualify for BPR. A company that shifts from trading to investment activity loses BPR going forward. Active monitoring is required.
Shareholder Protection Insurance
Shareholder protection insurance is life (and often critical illness) insurance designed to ensure that, on the death or critical illness of a shareholder, the surviving shareholders can buy out the deceased's shares at a fair price — and the deceased's estate receives cash rather than retaining an interest in a business in which the family may have no interest or expertise.
Without shareholder protection: A business partner dies. Their spouse inherits 50% of the business. The spouse has no knowledge of the business, no desire to be involved, but now has rights to 50% of profits, information about the business, and potentially the right to block decisions. The surviving partner has an unwanted co-owner. The estate has an illiquid asset they cannot value or exit.
With shareholder protection: The insurance policy pays out on death. The surviving shareholders use the proceeds to buy the deceased's shares from the estate at a pre-agreed price (typically set by the company's valuation formula in the shareholders' agreement). The estate receives cash. The surviving shareholders have full control. Both parties are better off.
The IHT interaction: Shareholder protection policies are typically written under a business trust (or cross-option agreement) so that the payout does not form part of the deceased's estate for IHT purposes. The structure matters: poorly drafted arrangements can inadvertently bring the payout into the estate, creating an IHT liability on the proceeds intended to fund the purchase of the shares.
Succession Planning vs Estate Planning: Two Different Questions
Succession planning asks: who will run the business after the current owner? This is primarily an operational question — identifying, developing, and transitioning to a successor (family member, management team, or external buyer) while the current owner is still alive and able to manage the process.
Estate planning asks: who will own the economic value of the business and how much IHT will be due? This is primarily a financial and legal question.
These questions are related but distinct. A business owner who has identified a management successor but has done no estate planning may have an IHT liability that forces a sale at a disadvantageous time, undermining the management succession. A business owner who has structured excellent BPR coverage but has no identified successor may leave the business to heirs who have no ability or desire to run it.
Optimal planning addresses both dimensions simultaneously.
Passing Shares to Children During Your Lifetime
Transferring shares to children during your lifetime can be an efficient way to remove future growth from your estate — the "gift" is the transfer of the shares at their current value, and any future appreciation accrues to the children.
If BPR applies: Lifetime transfers of BPR-qualifying shares are treated as potentially exempt transfers (PETs). If the donor survives seven years, the transfer leaves the estate entirely. If the shares qualify for BPR, the transfer is additionally covered by the relief (BPR can apply to lifetime transfers as well as death).
Family members in the business: Where children work in the business, transferring shares to them over time is a natural progression — it aligns ownership with management and gradually transitions control.
Employment income risk: If shares are transferred to family members at undervalue in connection with their employment in the business, HMRC may treat part of the gain as employment income rather than a capital gain. This requires careful advice.
Using a Family Investment Company for Business Owners
For business owners who have built significant personal wealth alongside the business (investment portfolios, property, pension), a Family Investment Company (FIC) can be used to hold non-business assets and transfer value to the next generation — while the business itself is held directly and may qualify for BPR.
The FIC and the BPR strategy work on parallel tracks: the business assets are protected from IHT by BPR; the investment assets are moved into the FIC structure to pass growth to the next generation outside the estate.
The Exit Alternative: Planning for a Sale
For many business owners, the most realistic plan is a clean exit — selling the business and estate planning for the proceeds. If no family member can or wants to run the business, forcing succession is often a mistake.
Estate planning for a post-sale business owner is different from planning for an ongoing business:
- Business Asset Disposal Relief (BADR) provides an 18% CGT rate on qualifying gains up to £1 million lifetime for 2026/27 (the rate was 10% until April 2025, rising to 14% in 2025/26 and 18% from April 2026; the lifetime limit of £1 million has applied since March 2020 when the prior £10 million Entrepreneurs' Relief limit was reduced)
- Pre-sale restructuring: Shares should be in the right ownership (personally, or through a trust, or spread across family members) before the sale. Post-sale, the proceeds are in the estate; pre-sale restructuring can affect the tax profile of the gain and the ongoing IHT position
- Trusts and post-sale planning: After a business sale, the typical challenges of a large liquid estate — investment strategy, IHT planning, next-generation planning — replace the business-specific challenges
Compliance Caveat
Business Property Relief, shareholder protection, Business Asset Disposal Relief, and succession planning involve complex legal and tax rules that change regularly. The information in this article is for general educational purposes and reflects the general position as understood in mid-2026. BPR rules, CGT rates (including BADR rates), and related reliefs may have changed since publication. The application of these rules to any specific business depends on its structure, activities, and assets. You should seek advice from a qualified solicitor and tax adviser before making any estate or succession planning decisions in connection with a business. The value of businesses and business assets can fall as well as rise.
