Inheritance Tax Planning for Business Owners: Business Relief and Succession Explained

Business Relief, historically referred to as Business Property Relief, reduces the value of certain business assets when calculating inheritance tax.

It recognises that business wealth may be tied up in trading operations, premises, equipment and company shares rather than readily available cash.

Without appropriate relief, inheritance tax could create financial pressure when a business passes between generations.

However, Business Relief is not a blanket exemption for everything owned by a business owner.

The business must satisfy qualifying conditions, and particular assets may be excluded.

Which Businesses Can Qualify?

Business Relief may apply to:

• A qualifying business or interest in a business.
• Shares in a qualifying unlisted company.
• Certain controlling shareholdings in listed companies.
• Qualifying land, buildings or machinery used in a business, subject to specific conditions.

The applicable rate depends on the type of asset and the inheritance tax rules.

A family trading company may qualify, while a business mainly holding investments may not.

The distinction between trading activity and investment activity is therefore fundamental.

Before April 2026, many qualifying trading businesses and unlisted company shares could receive unlimited 100% Business Relief.

That meant the full qualifying value could potentially be excluded from the inheritance tax calculation.

The rules changed on 6 April 2026.

A new allowance limits the amount of combined qualifying business and agricultural property eligible for 100% relief.

The New £2.5 Million Allowance

For deaths on or after 6 April 2026, the main provisions are:

The £2.5 million allowance is shared between qualifying assets eligible for 100% Business Relief and Agricultural Relief.

It is not a separate £2.5 million allowance for each relief.

The new rules are contained in Finance Act 2026.

No.

A business must first qualify for relief.

For example, a company mainly holding investment property may not qualify simply because its shares are worth less than £2.5 million.

Similarly, a qualifying trading company may hold assets that are excluded from Business Relief.

The allowance determines the amount of qualifying value that can receive 100% relief.

It does not turn otherwise ineligible assets into qualifying business property.

Is the £2.5 Million Allowance Additional to the Standard Nil-Rate Band?

Yes.

Business Relief operates separately from the standard inheritance tax nil-rate band.

The standard nil-rate band is £325,000 in 2026/27.

An eligible estate may benefit from both Business Relief and the nil-rate band.

However, the nil-rate band must be applied in the context of the full inheritance tax calculation, including earlier chargeable transfers and other assets.

The residence nil-rate band may also apply where its separate conditions are satisfied.

Consider a business owner who dies in October 2026.

They own shares in a qualifying unlisted trading company worth £2 million.

Assume the shares have been owned for the required period and qualify for 100% Business Relief.

There are no previous transfers affecting the new allowance.

The shares would make no contribution to the taxable estate in this simplified example.

Other assets owned by the deceased could still create an inheritance tax liability.

Key point: The new rules do not mean every qualifying family business is automatically subject to inheritance tax.

Now consider a business owner whose qualifying trading company shares are worth £4 million.

Assume the full £2.5 million allowance is available and there are no other complicating factors.

The £750,000 is the business value remaining after Business Relief, not necessarily the final taxable amount.

The standard nil-rate band and other relevant exemptions or reliefs must then be considered.

If the full £325,000 nil-rate band were available, there were no other assets or adjustments and the remaining value were taxed at 40%, the simplified calculation would be:

The effective tax burden on the qualifying business value above the £2.5 million allowance is often described as up to 20%, because 50% of that value remains exposed to a standard 40% tax rate.

However, the actual liability can be lower depending on the wider estate and available allowances.

Potentially.

The April 2026 reforms allow unused £2.5 million Business Relief and Agricultural Relief allowance to transfer between spouses and civil partners.

Where the first spouse's allowance is entirely unused, the survivor's estate may potentially have a combined allowance of £5 million for qualifying 100% relief assets.

This is separate from the transferable standard nil-rate band.

Example: A Family Business Worth £5 Million

Suppose a husband and wife own a qualifying family trading business.

The husband dies first, leaving his qualifying interests to his wife under arrangements that preserve the relevant unused allowance.

The wife later dies owning qualifying business interests worth £5 million.

Assume the full £5 million combined allowance is available and all the business interests qualify for 100% relief within that allowance.

The full £5 million qualifying value may be relieved.

Other assets in the estate would still need to be assessed separately.

What if the First Spouse Died Before April 2026?

HMRC guidance confirms that where the first spouse or civil partner died before 6 April 2026, the full £2.5 million allowance can be available for transfer under the new rules, even if Business Relief was claimed in the earlier estate.

This is a significant transitional provision.

However, personal representatives must establish the circumstances and make the relevant claim.

It should not be assumed that every family business will automatically qualify for the maximum transferable amount.

Often, but not always.

Shares in a qualifying unlisted trading company can be eligible for Business Relief.

The company must satisfy the relevant requirements, including restrictions concerning investment activities.

The ownership period is also important.

Generally, the deceased must have owned the qualifying business property for at least two years before the relevant transfer, although replacement property and other special rules can apply.

Does It Matter Whether the Shareholder Works in the Business?

Business Relief does not generally require every shareholder to work actively in the company.

A family member may hold qualifying shares without being involved in day-to-day management.

However, the nature of the company and the shareholding remain important.

Employment status alone does not determine whether Business Relief applies.

What About Minority Shareholdings?

Shares in a qualifying unlisted company can potentially receive Business Relief even where the shareholder does not control the company.

However, the valuation of minority shares can differ from a straightforward proportion of the entire company's value.

Share rights, restrictions, shareholder agreements and the company's circumstances may all affect the valuation.

An appropriate professional valuation is important.

Businesses consisting wholly or mainly of investment activities are generally excluded from Business Relief.

This can include businesses mainly dealing in securities, shares, land or buildings, or making or holding investments.

For example, a company whose main activity is holding a portfolio of rental properties may not qualify in the same way as an active trading company.

The distinction is not determined solely by the company's name or legal structure.

HMRC and the courts may consider the nature of its activities.

What About a Business With Both Trading and Investment Activities?

Mixed businesses can be more complicated.

A company may conduct substantial trading operations while also holding investment assets.

Whether the business qualifies depends on the overall activities and relevant legal tests.

Even where the company qualifies, particular assets may be excluded as excepted assets.

Business owners should therefore review the company's actual operations and asset composition rather than relying on a broad description such as "family company".

An excepted asset is an asset whose value may be excluded from Business Relief even where the business itself qualifies.

For example, a trading company may hold cash or investments that are not needed for its business activities.

That value may not qualify for relief.

However, cash is not automatically an excepted asset simply because the company has a substantial balance.

The purpose of the funds, the company's working capital needs and intended business use may be relevant.

Example: A Trading Company Holding Surplus Investments

Suppose a qualifying trading company is valued at £2 million.

Part of that value relates to an investment portfolio that is not used in the business and is not required for future business purposes.

The investment portfolio may be treated as an excepted asset.

This could mean Business Relief applies to less than the company's total value.

The exact amount requires a proper valuation and examination of the company's activities.

A business owner should not assume that every pound held within a trading company benefits from Business Relief.

Qualifying shares traded on the Alternative Investment Market, or AIM, receive different treatment under the April 2026 reforms.

Where the shares meet the relevant conditions, they generally qualify for 50% Business Relief rather than 100%.

The £2.5 million allowance for assets qualifying for 100% relief is not used by these shares.

This means the effective inheritance tax exposure can differ from that of qualifying unlisted trading company shares.

Not every AIM share qualifies for Business Relief.

The company's activities, ownership period and other conditions must still be considered.

AIM shares can also carry significant investment risk, including volatility and liquidity risk.

They should not be regarded as a guaranteed inheritance tax planning solution.

Potentially.

A business owner may wish to transfer shares to children while still alive.

A genuine outright gift to an individual can be a potentially exempt transfer for inheritance tax purposes.

However, the seven-year rule, Business Relief conditions and anti-avoidance provisions must be considered.

The new £2.5 million allowance can also be affected by qualifying lifetime transfers within the relevant period.

Are Gifts of Business Shares Free From Capital Gains Tax?

Not automatically.

A gift of shares is generally a disposal for capital gains tax purposes.

However, Business Asset Disposal Relief, Gift Hold-Over Relief or other provisions may be relevant depending on the circumstances.

Gift Hold-Over Relief may allow an eligible gain to be deferred rather than taxed immediately.

That does not necessarily mean the gain disappears permanently.

The recipient may inherit a reduced base cost, which can affect capital gains tax on a later disposal.

The inheritance tax and capital gains tax consequences should be considered together.

What if the Owner Continues to Control the Business?

Retaining employment, directorship or some involvement in a business does not automatically mean a share gift is ineffective.

However, retaining benefits or rights over gifted property can raise inheritance tax and other legal issues.

The exact share rights, ownership arrangements and transactions must be examined.

A business owner should not assume that transferring shares while retaining all economic benefits will achieve the intended inheritance tax result.

The death of a business owner can create immediate practical difficulties.

The company may depend on that individual for management, customer relationships, finance or decision-making.

Their death may also trigger provisions in shareholder agreements, partnership agreements or lending arrangements.

Where no succession plan exists, family members may inherit shares without having the experience or desire to run the business.

Disagreements may arise between beneficiaries who want to continue trading and those who prefer to sell.

Why Is a Will Not Always Enough?

A will determines how assets should pass on death, subject to the applicable law.

But it does not necessarily resolve how a company will operate during the transition.

For example, a will may leave shares equally to three children.

One child may already manage the business, while the other two have no involvement.

Equal share ownership may not provide an effective management structure.

Business succession planning therefore needs to consider governance as well as inheritance.

A shareholder agreement can set out what happens when a shareholder dies.

It may include provisions concerning the transfer, valuation or purchase of shares.

These arrangements can help protect the continuing business and provide clarity for beneficiaries.

However, certain binding contracts for sale can affect Business Relief eligibility.

The precise drafting matters.

What About Cross-Option Agreements?

Cross-option arrangements are sometimes used in business protection planning.

Broadly, they can give surviving shareholders an option to purchase the deceased shareholder's interest and the deceased's estate an option to require a purchase.

Properly structured arrangements may help provide flexibility without creating a binding sale contract from the outset.

However, their legal and tax treatment depends on the actual terms.

They should be prepared and reviewed by appropriately qualified advisers.

A business may be valuable without holding enough spare cash to meet a substantial inheritance tax bill.

For example, a company may own premises, equipment and stock but have limited liquid resources.

If inheritance tax becomes payable on business interests, beneficiaries may need to consider how to fund the liability.

Possible approaches include:

• Using other estate assets.
• Appropriate business protection arrangements.
• Borrowing, where suitable and available.
• A structured share purchase.
• Selling part of the business.
• Using statutory inheritance tax instalment provisions where eligible.

Each option has financial and legal implications.

Can Inheritance Tax on Business Assets Be Paid Over Ten Years?

From April 2026, the rules provide for inheritance tax attributable to qualifying Business Relief and Agricultural Relief property to be paid in equal annual instalments over ten years without interest, subject to the statutory conditions.

This can help reduce immediate pressure to sell qualifying business assets.

However, instalments do not eliminate the tax liability.

They also do not remove the need for careful cash-flow planning.

The circumstances of a sale or other event may affect whether outstanding instalments become payable sooner.

Trusts can be relevant where owners want to preserve a business for future generations or manage the interests of several beneficiaries.

However, trusts have their own inheritance tax rules.

The April 2026 reforms also introduced provisions for qualifying business and agricultural property held in relevant property trusts.

A £2.5 million allowance may apply under the trust rules, subject to the relevant conditions, allocations and transitional provisions.

Transfers into trusts may also trigger lifetime inheritance tax consequences.

Periodic and exit charges can arise.

The trust rules are not identical to the rules for an individual estate.

Trusts should therefore be considered for their genuine succession and governance purposes, rather than assumed to create an additional unrestricted inheritance tax allowance.

A practical business succession review should address more than tax.

1. Business Ownership

Identify who legally and beneficially owns the business interests.

Check share classes, voting rights and any restrictions on transfers.

2. Business Relief Eligibility

Review whether the business qualifies and whether any assets may be excepted.

Consider the required ownership period and the effect of recent transactions.

3. Business Valuation

Obtain a realistic valuation where appropriate.

The value of a company can change significantly, particularly following growth, acquisitions or changes in profitability.

4. Wills and Beneficiaries

Ensure the will reflects the intended succession arrangements.

Consider whether beneficiaries should receive ownership, economic value or another form of provision.

5. Shareholder and Partnership Agreements

Review the consequences of death, incapacity and retirement.

Check whether agreements are consistent with the will and inheritance tax objectives.

6. Liquidity and Business Protection

Consider how beneficiaries and continuing owners would fund any required share purchase or tax liability.

Insurance may be relevant, but policy ownership, trusts, premiums and tax treatment need appropriate advice.

7. Management Continuity

Identify who can operate the business if the owner dies or becomes unable to work.

Document key contacts, decision-making arrangements and essential business information.

A succession plan is most effective when the ownership, management and financial arrangements support one another.

A review may be appropriate when:

• The business approaches or exceeds £2.5 million in value.
• A spouse or civil partner dies.
• A child joins the business.
• Shareholders change.
• The company acquires investment assets.
• A sale or merger is being considered.
• The owner prepares for retirement.
• Shares are being gifted or placed into trust.
• Business protection arrangements are established or changed.
• A significant Budget or Finance Act alters the rules.

The new Business Relief allowance is legislated to remain at £2.5 million until April 2031, with subsequent increases linked to inflation under the current provisions.

Business valuations and the composition of the estate may nevertheless change during that period.

Regular reviews can help ensure that succession plans remain appropriate.

For business owners, inheritance tax planning needs to fit within a wider succession strategy.

At Telmar Estate Planning, the starting point can be understanding the owner's family circumstances, existing wills, business interests and intended beneficiaries.

This can help identify areas requiring further attention, such as ownership arrangements, succession wishes or coordination between personal and business planning.

Detailed Business Relief assessments, share valuations, shareholder agreements, capital gains tax planning and regulated financial products may require specialist tax, legal, accountancy or financial advice.

The objective should be to create arrangements that support both the family and the continuing business, rather than pursuing a tax outcome in isolation.

Business Relief remains an important inheritance tax provision for qualifying UK business interests.

From 6 April 2026, the full 100% relief is generally limited to £2.5 million of combined qualifying business and agricultural property per individual, with 50% relief on qualifying value above that amount.

Unused allowance may transfer between spouses and civil partners, potentially increasing the amount eligible for full relief to £5 million.

However, qualification is not automatic.

The business's activities, ownership period, asset composition and succession arrangements all matter.

For business owners, the most useful approach is to consider inheritance tax alongside wills, company governance, family objectives and the practical ability of the business to continue operating after a death.
