Business Property Relief (BPR)

Last verified: June 2026 (England & Wales)

You spend years building a business, taking risks, reinvesting, and making payroll. Then someone tells you that inheritance tax might force a sale, or dilute what you meant to pass on.

Since 6 April 2026, 100% relief has been capped at £2.5 million for qualifying agricultural and business property. Qualifying property above that level receives 50% relief, which can create an effective 20% inheritance-tax charge on the excess.

Unused allowance from a spouse or civil partner can sometimes be transferred, potentially increasing the allowance to £5 million, but the claim and figures still need checking.

Key idea: BPR can reduce inheritance tax on qualifying business assets, but you only get the outcome you expect if your Will, ownership structure, and succession plan all point in the same direction.

Quick-read summary

• BPR (sometimes called “Business Relief”) can reduce inheritance tax on certain business assets by 50% or 100%.
• The business must usually be a genuine trading business (not mainly an investment business).
• A two-year ownership requirement often applies (with some “replacement property” exceptions).
• Since 6 April 2026, 100% relief has been capped at £2.5 million for qualifying agricultural and business property. Qualifying property above that level receives 50% relief, which can create an effective 20% inheritance-tax charge on the excess.
• Since 6 April 2026, some shares traded on markets that do not meet HMRC’s definition of “listed”, such as Alternative Investment Market shares, receive 50% relief rather than 100%.
• BPR can be “wasted” by the way gifts are drafted in a Will (for example, where an exemption already applies).
• Planning is rarely just “tax”: you also need to protect the survivor, keep the business stable, and avoid family disputes.

Keeping this useful and safe

This page is general information to help you understand how BPR links into Wills and Will trusts. It is not tax advice, and it is not investment advice.

Where BPR touches investment decisions or specialist tax planning, the normal and sensible route is to involve an FCA authorised financial adviser and, where needed, your accountant.

Joined-up planning is the goal. Your Will plan should match your wider financial plan, so the outcome holds together in real life.

How I work with financial advisers (so your plan is joined up)

I always recommend speaking with a financial adviser where BPR is in play, especially if:

• the business value is material,
• you are considering AIM-style approaches,
• you expect a future sale or buy-out,
• there are second-family dynamics, or
• the 6 April 2026 changes may affect the numbers.

If you already have an adviser, then with your permission I am very comfortable speaking with them so any planning we do is holistic and joined up.

If you do not have an adviser, I work with trusted financial advisers I can introduce you to, with no obligation. You stay in control throughout, and you are free to choose whoever you want.

What BPR actually is

BPR reduces the value of qualifying business assets when inheritance tax is calculated.

In plain terms, it is intended to stop families having to sell a trading business (or give away control) just to raise inheritance tax after a death.

What can qualify (at a high level)

The clean way to think about BPR is “100% relief assets” and “50% relief assets”. The detail depends on the structure and the facts, but typical examples include:

Common 100% relief categories

• A business, or an interest in a business (for example, a sole trader business or a partnership interest).
• Shares in an unlisted company (often private limited companies).

Common 50% relief categories

• Controlling shareholdings in certain listed companies (where the conditions are met).
• Certain business-use assets (for example, land/buildings/machinery) where ownership and use sit in different places (such as personally owned assets used by a business you control), and some trust-held business-use assets.

Trading matters. A company that mainly holds investments (for example, a buy-to-let property investment company) often does not qualify in the way people expect.

The usual conditions people trip over

BPR is not automatic. Common trip points include:

• Business type: the trading versus investment distinction.
• Ownership period: often a two-year holding requirement (with limited exceptions).
• What the company owns: “excepted assets” or surplus assets not needed for the trade can reduce relief.
• A sale in progress: a binding contract for sale can change the analysis.
• Control and voting rights: especially where the business is listed or there are multiple share classes.

If any of those lines make you uneasy, that is usually a sign you should get the business looked at properly rather than assuming the relief will apply.

What changed on 6 April 2026

The 6 April 2026 changes are now in force, so older BPR pages can be misleading if they still talk about unlimited 100% relief or describe the changes as only “planned”.

In practical terms:

• 100% relief is now capped at £2.5 million for qualifying agricultural and business property.
• Qualifying property above that level receives 50% relief, which can create an effective 20% inheritance-tax charge on the excess.
• Unused allowance from a spouse or civil partner can sometimes be transferred, potentially taking the allowance up to £5 million.
• Some shares traded on markets that do not meet HMRC’s definition of “listed”, such as Alternative Investment Market shares, now receive 50% relief rather than 100%.

The headline question is no longer just “Does BPR apply?” It is also: “How much 100% relief is available, what happens above that level, and does the Will plan still work if the business is sold or restructured later?”

A short note on AIM and ISA wrappers

You may see inheritance-tax planning discussions that reference “AIM portfolios” and sometimes “ISA wrappers”.

Two key points, without going into product detail:

• These are usually conversations about investment selection and risk, not just tax relief.
• An ISA wrapper is about income-tax and capital-gains-tax sheltering. It does not turn an ineligible asset into an eligible one for BPR.

This is exactly where a financial adviser is valuable, because suitability and risk are personal. Then, once the investment approach is agreed, I can help ensure your Will planning is aligned so it still does what you want when the time comes.

How BPR gets “wasted” in Wills (and how to avoid accidental outcomes)

Even where BPR applies, drafting can reduce its usefulness. Three common patterns:

1) Gifts to an exempt beneficiary

If a business asset passes outright to a spouse/civil partner or to charity, inheritance tax is already exempt on that gift. Using BPR there can be a waste, because the relief is not being used to reduce tax on the chargeable part of the estate.

That does not mean “never leave the business to the survivor”. It means you should be deliberate about the trade-off between:

• the survivor’s security and control, and
• keeping relief available for the wider family.

2) Splitting residue between exempt and non-exempt beneficiaries

If the Will splits the whole estate proportionally (for example, part to charity and part to a non-exempt beneficiary), you can end up allocating part of the BPR asset to the exempt share.

A simplified illustration:

• Estate value: £1,000,000
• BPR-qualifying business value: £300,000
• Other assets: £700,000
• Will leaves 50% to charity and 50% to a sibling

Result (simplified):

• Charity share is exempt anyway.
• Only the sibling’s portion of the business attracts BPR, so the other portion is effectively wasted on the charity share.

The fix is not one magic clause. It is careful drafting so that the BPR assets are directed where they actually reduce inheritance tax, while still achieving the family objectives.

3) Leaving BPR assets to the survivor without thinking about the second death

A survivor may later:

• sell the business,
• be bought out by a business partner,
• stop trading, or
• restructure in a way that affects BPR.

If the asset stops qualifying, you can end up with an inheritance-tax-exempt transfer on the first death being replaced by a chargeable asset (often cash) in the survivor’s estate later.

When a “BPR trust” can be part of the answer

A “BPR trust” is not a special magic trust. It is usually a discretionary Will trust designed to receive business assets that may qualify for Business Property Relief.

The planning issue often arises on the first death of a couple. Leaving the business outright to a spouse or civil partner may feel simple, and the spouse exemption may mean no inheritance tax is due at that point. But it can also waste the chance to use BPR deliberately.

The second death is often the risk point. The survivor might sell the business, be bought out by a business partner, stop trading, or hold cash instead of a qualifying business asset. If that happens, the asset that once qualified for BPR may have turned into something taxable in the survivor’s estate.

A discretionary Will trust can sometimes help by receiving the qualifying business asset on the first death. The trustees can then use the trust flexibly, often guided by a Letter of Wishes, while avoiding a simple outright transfer that may cause problems later.

This can be relevant where:

• there is real uncertainty about whether the survivor will keep or sell the business;
• there are second-family dynamics;
• the business is intended for one child but fairness is needed across the family;
• the business partner or shareholder agreement may lead to a buy-out;
• the value of the business is high enough that the post-6 April 2026 relief cap needs proper advice.

A trust is not a tax cure-all.

Trusts have their own administration, reporting, tax and trustee duties. Where BPR is in play, the Will should usually be reviewed alongside the accountant, corporate documents and, where relevant, an FCA authorised financial adviser.

Quick checklist

You may want a BPR review if:

• your estate includes shares in a trading company, a partnership interest, or a sole trader business
• the business value is material compared to other assets
• you expect the business to be sold at some point (or there is a buy-back / cross-option arrangement)
• you have a second marriage, step-children, or unequal intentions between children
• you have heard friends mention AIM-style inheritance-tax planning and want to understand how it links to your Will
• your current Will leaves “everything to my spouse” without any business-specific logic

If you have already gifted or transferred shares, a partnership interest, a business asset, or business sale proceeds during your lifetime, record the facts while they are still clear. The Lifetime Gifts Log can help capture the date, value, ownership percentage, transfer type, relief being considered, and where the supporting evidence is kept.

Use your Finance Log or Property Log for business assets you still own. Use the Lifetime Gifts Log where there has been a lifetime gift, transfer, loan write-off or related arrangement.

What to consider (before anyone drafts anything)

• Who must be protected first: the survivor, the business, or the children (often it is all three, but the order matters).
• Who should control the business after death: and what the shareholder or partnership documents actually say.
• Liquidity: if relief is reduced or capped, where would any tax be paid from without destabilising the business?
• Timing: how the post-6 April 2026 rules affect the numbers, and whether the Will plan still works if the business is sold, restructured or bought out later.
• Fairness: how to balance a “business child” and a “non-business child” without creating a dispute.
• Risk: AIM-style planning can carry investment risk. Tax relief does not remove market risk.
• Joined-up advice: accountant, corporate solicitor (if needed), financial adviser (if needed), and the Will all have to align.

Cases

A family engineering firm with two children, only one in the business

Dad wants the child in the business to take over, but also wants the other child to be treated fairly. With a clear succession plan and Will drafting that matches the share structure, the business can continue without forcing a rushed sale. Without that alignment, the family risks either deadlock or a forced buy-out at the worst time.

A couple where the first death leaves everything to the survivor

On the first death, the spouse exemption means no inheritance tax. The risk appears later, if the survivor sells the business and holds cash, or if BPR rules tighten further. A structured plan can preserve flexibility and reduce the chance of an avoidable tax shock on the second death.

A shareholder with a business partner and a buy-back agreement

The paperwork says the partner can buy the shares back. The family assumes they will keep the shares. A coordinated plan (Will plus the business documents) prevents the family being surprised by an automatic route to sale and helps manage how proceeds are protected and distributed.

A property-heavy company mistaken for a “trading business”

The owner assumes “it’s a company, so BPR applies.” In reality, investment activity can disqualify relief. With early clarification, the owner can plan based on real numbers. Without it, the family may discover the problem only after death, when options are limited.

A portfolio built around AIM-style inheritance-tax planning

The family expects 100% relief after two years. The post-6 April 2026 move to 50% relief for certain shares changes the maths, and market volatility remains. A sensible plan involves a financial adviser for investment suitability, then aligns the Will so the estate plan still does what the family intends.

Does BPR apply automatically if I own a limited company?

No. Relief depends on whether it is a qualifying business and whether the relevant conditions are met (including the trading versus investment point).

Do I have to own the business or shares for two years?

Often, yes. There are exceptions (for example where qualifying business property replaces other qualifying business property), but the two-year point is a common trip hazard.

What about AIM and ISA wrappers?

AIM-style planning is often discussed in the investment world because some shares traded on certain markets have historically been treated as eligible for BPR after the holding period. Since 6 April 2026, some shares traded on markets that do not meet HMRC’s definition of “listed”, such as Alternative Investment Market shares, receive 50% relief rather than 100%.

An ISA wrapper is about income-tax and capital-gains-tax sheltering. It does not create BPR eligibility where it does not already exist.

If you are considering any investment route, an FCA authorised financial adviser should review suitability and risk. Then I can ensure your Will planning is aligned.

Is leaving the business to my spouse always the best answer?

Not always. It can be right for security and simplicity, but it can also waste relief and create second-death risk if the asset stops qualifying later. This is a planning decision, not a template rule.

Should I use a discretionary trust for BPR?

Sometimes it helps, especially where you need flexibility and protection between first and second death. But trusts have their own tax and admin regime, so it should be used only where it solves a specific problem better than simpler routes.

If some inheritance tax is due, can it be paid in instalments?

In some scenarios, yes. The rules are technical and can change, so it should be checked as part of the wider succession plan rather than assumed.

Optional technical note

BPR sits within the inheritance tax framework and is heavily fact-dependent. The practical takeaway is that headline relief rates are not enough; the business type, ownership, documentation, and what happens after death all affect the outcome.

Next steps

1. List what the business assets actually are (shares, partnership interest, sole trader business, business-use property, cash in the company).
2. Confirm how the business is structured and who controls it (share classes, voting rights, partnership agreement).
3. Decide the real-world outcome you want (who controls, who benefits, what happens if the business is sold).
4. Bring your accountant and, where appropriate, a financial adviser into the loop. With your permission I am comfortable speaking to them so the plan is joined up.
5. Then align the Will and any Will trust drafting so it supports the plan rather than accidentally cutting across it.
