Estate Planning for Business Owners: Protecting Wealth and Succession

Business owners have unique responsibilities when planning for the future. In addition to providing for their families, they must also ensure the continuity of the enterprise they have built and navigate complex tax rules. Without a clear plan, the death or incapacity of an owner can lead to uncertainty, family disputes and heavy tax liabilities. This guide explains why estate planning matters for business owners, outlines the key documents and structures available and highlights upcoming changes to UK inheritance tax reliefs.

Why estate planning matters

Every business owner should consider what would happen to the business if they died or lost mental capacity. A well‑structured estate plan can:

• Protect your family’s wealth by ensuring that business assets pass tax‑efficiently and according to your wishes.
• Provide continuity for the business so that operations can continue smoothly, avoiding disruption to employees, customers and suppliers.
• Avoid conflict between family members and co‑owners by setting out a clear succession plan and funding arrangements.
• Maximise reliefs and allowances available under UK tax law, such as business property relief (BPR) and agricultural property relief (APR).

What happens to a business without a plan?

The way a business is owned determines what will happen if the owner dies or becomes incapacitated.

Sole traders

In a sole tradership there is no distinction between the business and the owner. On death the business forms part of the personal estate. Personal representatives can carry on the trade for a limited period and may need to sell assets to pay debts and tax. A will can give representatives the authority to continue running the business or to sell it on favourable terms. Without clear instructions, the business may be forced to close quickly, damaging goodwill and value.

Partnerships

Unless there is a written partnership agreement, the death of a partner automatically dissolves the partnership. The surviving partners have no right to purchase the deceased’s share and must wind up the business. A partnership agreement can give surviving partners an option to buy the deceased’s share and the deceased’s estate an option to sell. This “cross option” structure avoids creating a binding obligation to sell, which could otherwise prevent the shares qualifying for BPR. The agreement should specify how the price is determined and be funded by life insurance to provide cash when needed.

Limited companies

Shares in a private company form part of the shareholder’s estate. If the articles of association and any shareholders’ agreement contain pre‑emption rights or compulsory transfer provisions, the deceased’s personal representatives must follow those rules. A shareholders’ agreement can include cross option clauses giving surviving shareholders the right to buy the shares and the estate the right to compel the purchase. A life assurance policy can pay out on death so that funds are available to buy the shares at market value. It is important that the agreement is drafted as an option rather than an obligation so that BPR is not lost.

Essential estate planning documents

Will

• A will is the cornerstone of any estate plan. For business owners it should:
• Appoint executors who understand the business or can instruct advisors.
• Leave business interests as specific legacies to make full use of BPR and APR. Leaving the entire estate to a spouse may waste the relief because the spouse exemption already removes inheritance tax.
• Provide authority for the executors to continue running the business, sell it or wind it down, if appropriate.
• Coordinate with shareholder and partnership agreements so that the will does not contradict other succession arrangements.

Shareholder or partnership agreement

These agreements govern what happens to shares or partnership interests on death or incapacity. Key provisions include:

• Pre‑emption rights requiring a departing owner’s shares to be offered to existing shareholders before external buyers.
• Cross options giving surviving owners the right (but not the obligation) to purchase, and the estate the right to compel a sale.
• Valuation mechanisms to determine the price fairly.
• Funding arrangements, often backed by life assurance policies held in trust so that proceeds fall outside the estate for inheritance tax purposes.

Business Lasting Power of Attorney (Business LPA)

Most people are aware of lasting powers of attorney for personal finances and health matters. A Business LPA deals specifically with business decisions. It allows the owner (the donor) to appoint attorneys to manage business affairs, such as signing contracts, paying staff and accessing bank accounts, if the donor loses capacity or is temporarily unavailable. A separate Business LPA may be needed because regulatory restrictions can prevent a spouse or personal attorney from acting for the business. The document must be registered with the Office of the Public Guardian before use.

Trusts

A discretionary trust can hold business assets after death. Assets that qualify for BPR can be appointed into the trust free of inheritance tax and later bought out of the trust and returned to the surviving spouse’s estate, allowing BPR to be claimed twice. This “double dip” arrangement must be carefully structured to avoid unnecessary tax charges and comply with the trust’s periodic and exit charge regime. Trusts can also protect assets for minor children or vulnerable beneficiaries and provide flexibility if the future of the business is uncertain.

Life assurance policies

Life insurance can provide the cash needed to pay inheritance tax, purchase shares under cross options or inject funds into the business after a key person’s death. Policies should usually be written in trust so that the proceeds fall outside the estate and are available quickly. The sum assured should reflect the expected value of the business interest and any tax due.

Tax planning for business owners

Inheritance tax and Business Property Relief

Inheritance tax (IHT) is charged at 40 % on the value of an estate above the available allowances. Business Property Relief (BPR) can reduce the taxable value of qualifying business assets by 50 % or 100 %. BPR generally applies to shares in unquoted trading companies, interests in trading partnerships and certain sole trader business assets. From 6 April 2026 the UK Government will cap BPR (and agricultural property relief) at £2.5 million per person. Spouses and civil partners can transfer any unused allowance to the survivor, potentially giving a couple up to £5 million of BPR. For qualifying assets above the cap, IHT will be payable at 20 %, half the normal rate. These allowances sit alongside the nil‑rate band (£325,000) and residence nil‑rate band (£175,000), which can also be transferred between spouses.

To qualify for BPR:

• The business must be a trading business, not mainly holding investments.
• The owner must have held the assets for at least two years.
  There must be no binding contract for sale on death.
• Options to buy or sell shares (rather than obligations) are therefore essential.
• Not all types of property qualify, for example, non‑trading land or buildings used by a company controlled by the owner receive only 50 % relief.

Lifetime gifts and Potentially Exempt Transfers (PETs)

Giving away business assets during life can reduce the value of your estate and potentially qualify for BPR. Gifts to individuals are PETs: they become exempt from IHT if you survive seven years after making the gift. Gifts to discretionary trusts are usually chargeable transfers and may attract an immediate 20 % tax if they exceed the nil‑rate band, but BPR can reduce or eliminate that charge if the assets qualify and have been owned for two years. Take care to avoid gifts with reservation of benefit, where the donor retains use or control of the gifted asset, as these remain part of the taxable estate.

Capital gains tax and other taxes

Transferring business assets during life can trigger capital gains tax (CGT). Reliefs such as Business Asset Disposal Relief (BADR) (formerly Entrepreneurs’ Relief) and Hold Over Relief may reduce or defer CGT. Specialist advice should be taken to balance CGT and IHT considerations.

Succession planning and business continuity

Estate planning is not just about who receives your assets. Business owners should develop a succession plan that covers:

• Leadership and management – identify and train successors within the family or management team well before retirement or death.
• Ownership structure – decide whether the next generation will own and run the business or whether it will be sold. If selling, prepare the business for sale to maximise value.
• Funding the transition – ensure that any purchase of shares under a cross option is funded by life assurance or other means so that the surviving owners and the estate can act quickly.
• Communication – talk to family members, co‑owners and key staff about your intentions. Clear communication reduces the risk of disputes and helps everyone plan ahead.

Integrating personal and business planning

Your personal estate plan and business succession plan must work together. Ensure that your will, Business LPA, shareholder or partnership agreement, trust deeds and insurance policies are consistent. Update your plans whenever there is a change in your personal circumstances (such as marriage, divorce or a new child) or a change in your business (such as taking on new partners or shareholders).

Review and next steps

Laws and personal circumstances change. Review your estate plan regularly, at least every three to five years and after any significant business event. Upcoming tax reforms such as the new BPR cap make early advice particularly important. Work with legal, tax and financial professionals to create a tailored plan that protects your family, your business and your wealth.

Conclusion

Effective estate planning enables business owners to control what happens to their business, protect their family’s wealth and minimise tax liabilities. By putting in place a well‑drafted will, shareholder or partnership agreements, a Business LPA, appropriate trusts and insurance, and by considering lifetime gifts and tax reliefs, you can ensure your business continues to thrive for the benefit of future generations.
