Is a business subject to Inheritance Tax in the UK?

February 20, 2026

For many business owners, the family firm represents far more than a financial asset. It is a lifetime of work, a source of income, and often a legacy they hope to pass on intact to the next generation. But when it comes to Inheritance Tax, businesses are not automatically protected. With major changes to Business Relief taking effect from April 2026, understanding whether Inheritance Tax (IHT) applies to your business, and how much could be at stake, has never been more important.

Key takeaways

  • A business forms part of your estate for Inheritance Tax purposes
  • Business Relief can significantly reduce the tax due, but major reforms are coming
  • From April 2026, 100% relief is capped at £2.5 million
  • Investment businesses and AIM shares will generally qualify for 50% relief only
  • The £2.5 million allowance is transferable between spouses, even if the first spouse died before April 2026
  • Gifts made since 30 October 2024 may still fall under the new rules
  • Early, regulated planning, including the use of trusts and life insurance, can reduce pressure on the next generation

How a business fits within your estate for Inheritance Tax

If you are asking do you pay inheritance tax on a business?, the short answer is yes. A business forms part of your estate for Inheritance Tax purposes and is assessed alongside your personal assets when HMRC calculates the tax due on death.

For many years, Business Relief has softened this impact, often eliminating IHT entirely on qualifying businesses. This has allowed family firms to pass from one generation to the next without being forced into sale.

However, this long-standing position is changing.

Inheritance Tax on business, property, and other assets

When someone dies, HMRC assesses the total value of everything they owned at that time. This is known as their estate, and it includes business interests alongside personal property and other assets.

Which business assets are included in your estate?

Business assets commonly included for inheritance tax purposes include:

  • shares in private companies
  • business premises and land
  • plant and machinery
  • goodwill and intellectual property

Even where a business is family-run or owner-managed, it does not automatically sit outside the tax system. Without reliefs, business property and assets are treated in much the same way as any other part of the estate.

Who pays the Inheritance Tax?

A common concern is whether the business itself pays Inheritance Tax. It does not. IHT is a personal liability, payable by the deceased’s estate or, in some cases, by the beneficiaries who inherit the assets.

This distinction matters. Business value is often tied up in shares or property rather than cash. Without planning, families can face a substantial tax bill with limited liquidity, putting pressure on the business itself.

The standard allowance and the wider estate

Every individual currently benefits from a £325,000 nil-rate band, meaning the first £325,000 of their estate is taxed at 0%. Any value above this may be taxed unless exemptions or reliefs apply.

Business assets are assessed alongside the wider estate, including property, savings, and investments. Understanding how these elements interact is essential when assessing overall Inheritance Tax exposure.

Business Relief and Inheritance Tax on business assets

Business Relief (BR) is one of the most valuable Inheritance Tax reliefs available to business owners. In simple terms, it reduces the taxable value of qualifying business assets when calculating Inheritance Tax.

Instead of taxing the full market value, some or all of it may be disregarded for tax purposes. For many families, this relief has been the deciding factor between passing a business on intact or being forced to sell assets to meet a tax bill.

Business Relief reforms from April 2026

From 6 April 2026, significant reforms to Business Relief will take effect, bringing the era of unlimited 100% relief to an end.

What the 2026 Business Relief reforms mean in practice

A new £2.5 million cap will apply to the combined value of qualifying business and agricultural assets.

  • The first £2.5 million will continue to receive 100% Business Relief
  • Any value above £2.5 million will receive 50% relief, resulting in an effective inheritance tax rate of 20%

For business owners with valuable trading companies, this change alone can create a substantial Inheritance Tax exposure.

Investment businesses, AIM shares, and Inheritance Tax

Not all businesses are treated equally for Inheritance Tax purposes. A clear distinction exists between trading businesses and investment businesses.

Trading businesses – such as manufacturers, retailers, and service providers – usually qualify for Business Relief. Investment businesses, including many buy-to-let property companies and businesses that mainly hold investments, generally do not.

AIM shares and the loss of full Business Relief

AIM-listed shares are treated differently under the new rules. From April 2026, AIM shares will generally qualify for 50% relief only, with no £2.5 million allowance available, regardless of value.

Many investors have historically used AIM portfolios as an Inheritance Tax planning tool, making a review of existing arrangements particularly important.

Trusts, lifetime planning, and passing on business assets

Reducing Inheritance Tax exposure often starts with planning between spouses and civil partners. Since the 2025 Budget, the £2.5 million Business Relief allowance is transferable, allowing couples to protect up to £5 million of qualifying business assets.

Importantly, this applies even if the first spouse died before April 2026.

Gifting business assets and the seven-year rule

Lifetime gifting is another commonly used strategy. Under the seven-year rule, gifting shares during your lifetime can move value outside your estate entirely, provided you survive for seven years.

While effective, gifting requires careful structuring to ensure you retain appropriate control and income while avoiding unintended tax consequences. In some cases, trusts may form part of a wider succession strategy, particularly where family dynamics or future protection are key concerns.

Do businesses pay capital gains tax?

No. Capital gains tax is not paid by the business itself. It is a personal tax, paid by individuals when they sell business assets or shares they own.

If you sell your business during your lifetime, you may pay capital gains tax on any gain, rather than the business being subject to inheritance tax on death. From April 2026, the Business Asset Disposal Relief rate increases to 18%, which should be considered as part of long-term planning.

These decisions often sit within wider  later life planning, particularly where retirement income, succession, and family protection need to be balanced.

Using life insurance to manage Inheritance Tax on a business

One of the most common challenges families face is the liquidity gap: inheriting a valuable business but lacking the cash to pay the Inheritance Tax bill.

Life insurance, such as Whole of Life or Gift Inter Vivos policies written in trust, can provide a dedicated cash reserve to meet future Inheritance Tax liabilities. This can help protect the business itself and reduce the risk of forced asset sales.

Key challenges business owners should be aware of

Two issues frequently catch families off guard:

  • liquidity pressure, where tax is due but cash is not readily available
  • excepted assets, such as excessive cash or non-essential investments held within the business, which can reduce Business Relief unexpectedly

What feels like prudent caution can sometimes work against you from a tax perspective, particularly as HMRC scrutinises how business assets are used.

Planning ahead for your business, estate, and family

The period before 6 April 2026 represents a valuable planning window. Now is the time to review ownership structures, governance, valuation, and lifetime planning strategies in light of the new rules.

Anti-forestalling provisions are already in effect. Gifts made since 30 October 2024 will be assessed under the new limits if the donor dies after April 2026.

When it comes to inheritance tax and family businesses,doing nothing is often the most expensive option. Even with the new limits, the UK remains a relatively supportive environment for family business succession, provided you plan early and review regularly.
