Inheritance Tax for Business Owners UK: Planning Beyond Business Property Relief

Updated: 17 May 2026 • Reading time: 9 min

Business Property Relief (BPR) is often described as the “get out of IHT free” card for business owners — but this is an oversimplification that can lead to serious planning mistakes. BPR has limits, qualifying conditions, and carve-outs. A robust IHT strategy for business owners combines BPR with pensions, life insurance, lifetime gifting, and carefully drafted wills.

Business Property Relief: The Basics

BPR reduces the taxable value of qualifying business assets at death (or on a chargeable lifetime transfer into a trust). From 6 April 2026, significant reforms took effect:

This reform means that business owners with substantial estates need a more active multi-tool approach rather than relying solely on BPR to shelter the business.

Assets That Do Not Qualify for BPR

HMRC scrutinises BPR claims carefully. Common disqualifications include:

For mixed trading/investment businesses — common for solicitors, accountants, or property developers who also hold investment portfolios — a regular review of the business’s qualifying status is essential.

Pensions as an IHT Planning Tool

For business owners, a self-invested personal pension (SIPP) or small self-administered scheme (SSAS) can be a highly efficient wealth-holding structure. Pension funds are:

Business owners who have taken profits from the business should consider whether investing in a pension rather than accumulating cash on the personal balance sheet achieves a double benefit: income tax relief on contributions and IHT efficiency on the fund value.

Life Insurance in Trust

A whole-of-life policy written in a discretionary trust is one of the most flexible IHT planning tools for business owners. Key uses include:

Funding a Buy-Sell Agreement

Where a business has multiple shareholders or partners, a cross-option agreement (buy-sell agreement) obliges the surviving owners to buy the deceased’s share and obliges the estate to sell. The policy pays the purchase price to the surviving owners, funded by premiums they have paid. The estate receives cash — not illiquid business property — which is simpler for IHT purposes and avoids a forced sale.

Covering the IHT Liability

Where BPR is unavailable, limited, or uncertain — particularly for assets above the £1 million 100% cap — a whole-of-life policy in trust can fund the IHT bill. The payout goes directly to the trust and is available to the executors within weeks of death, avoiding the need to sell illiquid business assets to pay HMRC within six months.

Premiums paid into a policy held in trust may qualify as normal expenditure out of income — an exempt transfer if they are regular, habitual, and do not reduce the standard of living of the donor.

Will Planning for Business Owners

Many business owners default to leaving everything to their spouse, which is IHT-exempt but often wastes BPR. If BPR qualifies at death, leaving the business to a surviving spouse does not use BPR — BPR is only relevant against a taxable transfer. The result is that the full business value sits in the surviving spouse’s estate and will be taxed on their death at 40%, potentially without BPR if the spouse has disposed of the business by then.

Better strategies include:

Lifetime Gifting Strategies

Business owners can make lifetime gifts of business property to reduce their estate:

Succession Planning Checklist

A business owner’s IHT checklist should include:

  1. Confirm which business assets qualify for BPR and at what rate — get a written opinion from an adviser
  2. Review whether the business has excepted assets that should be extracted or reduced before death
  3. Check whether a buy-sell agreement exists and whether it is cross-option structured (so BPR is not denied)
  4. Ensure life insurance policies covering the business are written in trust — not held personally
  5. Review pension nominations — are they up to date and tax-efficient given potential 2027 pension reform?
  6. Check that the will does not leave BPR assets to the surviving spouse, wasting the relief
  7. Consider whether lifetime gifts to children or a trust would reduce the estate efficiently
  8. Review regularly — particularly after a significant change in business value or on the death of a co-owner

Frequently Asked Questions

What is Business Property Relief and what rate does it give?

Business Property Relief (BPR) is an IHT relief that reduces the taxable value of qualifying business assets. From 6 April 2026 the rules changed: BPR at 100% is capped at £1 million of qualifying business property per person (£2 million for spouses claiming the transferable NRB equivalent). Assets above that cap qualify at 50%. Qualifying assets include: unincorporated business interests, shares in an unquoted trading company (including AIM-listed shares held for at least two years), and a controlling shareholding in a quoted company. Business property must have been owned for at least two years immediately before death to qualify.

What business assets do not qualify for BPR?

Several asset types are specifically excluded: (1) a business or interest in a business mainly dealing in investments (including property letting), land, or securities — HMRC applies a 'wholly or mainly' test and will deny BPR if more than 50% of the business activity is non-trading; (2) excepted assets — cash, shares in subsidiary investment companies, or other assets not used in the business during the two years before death; (3) companies in the process of being wound up; (4) a business subject to a binding contract for sale at date of death. Buy-sell agreements triggering BPR exclusion are a common planning pitfall for partnership and company shareholders.

How can a business owner use their pension to reduce IHT?

Pension funds are generally outside the deceased's estate for IHT purposes if properly structured. A business owner can build significant wealth inside a self-invested personal pension (SIPP) or small self-administered scheme (SSAS) and nominate beneficiaries via an expression of wishes — the pension trustees then pay the death benefit outside the estate. From April 2027, inherited pension funds will be brought within the IHT net (subject to final legislation), but even so, pension wealth can be drawn and reinvested in other IHT-efficient structures during lifetime.

How does life insurance work in IHT planning for business owners?

A whole-of-life or term assurance policy written in trust pays out to the trustees on death, outside the estate and free of IHT. Business owners commonly use this to: (1) fund a buy-sell agreement — the policy pays the purchase price to the surviving shareholders or partners so the estate can sell its business interest without a forced sale; (2) cover an IHT liability — a whole-of-life policy written in a discretionary trust can pay the IHT bill, preventing executors having to sell the business to meet the charge before BPR or a tax deferral election is accepted. Premiums paid into the trust may be exempt gifts if they qualify as normal expenditure out of income.

What will-planning strategies reduce IHT for business owners?

Key will-planning strategies include: (1) ensuring BPR assets pass to individuals (not the exempt spouse) so BPR is not wasted — a spouse exemption on BPR assets simply defers IHT without using BPR, whereas leaving them to adult children uses BPR at death; (2) using a discretionary trust in the will to hold BPR assets, giving flexibility to appoint them out over time; (3) incorporating a business property NRB trust to use the nil-rate band against non-BPR assets; (4) considering a 'wait and see' or 'hybrid' clause so the executors can assess BPR availability at death before making distributions; (5) for AIM shares held via an ISA, ensuring that the will deals with the ISA administration authority so the beneficial BPR treatment (if still applicable) is not lost through delay.

Can a business owner give away business assets to reduce IHT during their lifetime?

Yes, but with care. An outright gift of business property is a potentially exempt transfer (PET) — no IHT if the donor survives seven years. BPR may apply at the date of the gift if the conditions are met, but BPR does not apply at the date of death if the donee no longer owns the property (replacement property rules apply). Business owners can also use an enterprise investment scheme (EIS) or seed EIS to invest trading gains in BPR-qualifying shares, and can make gifts into trust subject to the relevant property regime. Large gifts may require careful consideration of the donor's post-retirement income needs.
