Business Protection
Protecting Business Value, Ownership and Continuity Through Effective Estate Planning
Building a business takes years. Protecting what you have built — and ensuring it passes on intact, or transfers on your terms — requires deliberate planning that goes well beyond a standard will.
​
For business owners, the estate planning questions are more complex than they are for most. Who inherits your share of the business? What happens to trading continuity if you die or lose capacity? Is there a liability that must be met in cash within six months of death? Do your co-owners have the means and the legal mechanism to acquire your interest if they need to?
​
These are not hypothetical concerns. They are practical questions with real consequences — for your family, for your business partners and for the employees and customers who depend on the business continuing to operate.
The Inheritance Tax Dimension
Business Property Relief has historically provided meaningful protection against inheritance tax for owners of qualifying trading businesses. A business that attracted full relief could pass to the next generation without an IHT charge, preserving both the asset and the continuity of the enterprise.
​
That protection is becoming more conditional. From April 2026, the reforms confirmed in the Autumn Budget 2024 cap 100% Business Property Relief at £2.5 million per individual. Business value above that threshold attracts relief at 50% only — an effective inheritance tax rate of 20% on the excess.
​
For a business valued at £4 million owned by a single individual, this creates a potential IHT liability of £120,000 on the value above the cap, even before personal assets and pension funds are considered. Where pension funds are also brought within the taxable estate from April 2027, as currently proposed, the combined liability across the estate may be considerably higher.
​
The question this page addresses is a practical one: once a liability exists, how is it met — without forcing a sale of the business, disrupting trading continuity or placing executors and beneficiaries in an impossible position?
The Liquidity Problem for Business Estates
Inheritance tax is due within six months of the date of death. HMRC does not wait for probate to be concluded, for a business to be valued, or for a suitable buyer to be found.
​
For business owners whose primary asset is the business itself, meeting that liability in cash — within the required timeframe — is not straightforward. The options available to executors without prior planning are limited and often damaging:
​
-
Selling a stake in the business to a third party, potentially at a discount and under time pressure.
​​
-
Bringing in outside investors on terms that dilute family or co-owner control.
​​
-
Applying for the instalment option — which allows IHT on qualifying business assets to be paid over ten years, but accrues interest and does not reduce the underlying liability.
​​
-
Drawing on personal assets that may not exist in sufficient quantity.
​​
None of these outcomes is inevitable with proper planning. But without it, they become likely.
Whole-of-Life Assurance Written in Trust
The most widely used mechanism for addressing a known or anticipated IHT liability on a business is a whole-of-life policy written in trust.
​
The structure works as follows. A whole-of-life policy is taken out on the life of the business owner — or on a joint or last survivor basis for a married couple — for a sum that is broadly equivalent to the anticipated IHT liability. The policy is written in trust from the outset, which means the proceeds sit outside the taxable estate. On death, the trust receives the policy proceeds directly, without waiting for probate and without the sum forming part of the estate and attracting a further IHT charge on itself.
​
The trustees — usually family members or professional trustees — can then give those funds to the executors to pay the IHT liability, so the business can pass on intact without any forced sale.
​
The key considerations in structuring such a policy correctly include:
​
The Sum Assured
The policy should be calibrated to the anticipated liability, taking into account the likely business valuation, the BPR position, other assets in the estate and the available nil-rate bands. As business values and the legislative framework change, the sum assured should be reviewed periodically.
​
The Trust Structure
The policy must be written in trust correctly to ensure the proceeds fall outside the estate. The choice of trust — discretionary, flexible or otherwise — affects how the proceeds can be distributed and should be considered alongside the wider estate plan.
​
Underwriting
Whole-of-life policies become more expensive and, in some cases, unavailable as age and health change. Acting while the business owner is in good health and at a younger age produces significantly better terms. Delay has a direct financial cost.
​
Ongoing Review
The policy should be reviewed whenever there is a material change in business value, ownership structure or the legislative position affecting BPR.
Shareholder and Partnership Protection
Where a business has more than one owner, the death or incapacity of a co-owner creates a distinct set of problems that life assurance and trust planning can address.
​
Without any arrangement in place, the deceased owner's share of the business will pass under their will or intestacy rules — potentially to a spouse, children or other beneficiaries who have no involvement in or knowledge of the business. The surviving owners may find themselves in business with people they did not choose and cannot easily buy out.
​
The standard mechanism for addressing this is a cross-option agreement combined with life assurance on each owner's life, written in trust for the benefit of the other owners.
​
A cross-option agreement gives the surviving owners the option to purchase the deceased's share and the deceased's estate the option to require the surviving owners to purchase it. Neither party is obliged to exercise their option — which is important for Business Property Relief purposes, as a binding obligation to sell can affect whether the asset qualifies for relief — but both have the mechanism available if they choose to use it.
​
The life assurance provides the funds. On the death of an owner, the policy proceeds are paid into trust and made available to the surviving owners to fund the purchase. The deceased's estate receives fair value for the business interest in cash, without the need for a distressed sale or external financing. The surviving owners retain full control.
​
For partnerships and limited liability partnerships, the principles are similar, but the legal documentation differs. The arrangement should be reviewed whenever ownership changes, a new partner joins or the value of the business changes materially.
Key Person Protection
Separately from the ownership and estate planning dimensions, business owners should consider the financial impact of losing a key individual whose contribution is central to the business's value and trading performance.
​
Key person insurance provides a lump sum payable to the business — not into trust, but to the company directly — on the death or critical illness of a named individual. It is designed to give the business time and financial capacity to manage the transition: recruiting a replacement, reassuring clients and lenders, and absorbing any revenue disruption.
​
Key person cover is a business expense and is treated differently from personal life assurance for tax purposes. The tax treatment depends on the purpose of the policy and requires careful structuring. It sits alongside, rather than in place of, the personal estate planning arrangements described above.
Lasting Powers of Attorney for Business Owners
Business protection is not only about what happens on death. Loss of mental capacity – through illness, accident or cognitive decline – can be equally disruptive to a trading business if the right legal structures are not in place.
​
A Property and Financial Affairs Lasting Power of Attorney allows a named attorney to manage financial affairs on behalf of the donor if they lose capacity. For a business owner, the arrangement means the attorney can — subject to any restrictions in the LPA — continue to operate the business, manage accounts, and make decisions that keep the enterprise functioning.
​
Without an LPA, an application to the Court of Protection for a deputyship order is required. This process typically takes many months, involves court supervision and ongoing reporting obligations, and may result in an appointed deputy who does not fully understand the business or the owner's intentions.
​
Every business owner should have a Property and Financial Affairs LPA in place. It is one of the most straightforward and cost-effective elements of business protection planning.
How Wills, Tax & Trusts Ltd. Can Help
Ray L. Best and the team at Wills, Tax & Trusts work with business owners and their professional advisers to address the full range of business protection planning — from inheritance tax liability analysis and whole-of-life assurance structuring to shareholder agreements, LPAs and the wider estate plan.
​
Business protection planning is most effective when it is approached as an integrated exercise rather than a series of disconnected products. The IHT position, the ownership structure, the liquidity arrangements and the personal estate plan need to work together — and they need to be reviewed as the business and the legislative landscape evolve.
