Business Property Relief 2026: How BPR Cuts Your IHT Bill

Quick answer

Business Property Relief cuts the inheritance tax due on a qualifying business by reducing its value by 100% or 50% before the 40% IHT rate is applied. A genuine trading business or unquoted trading company shares, owned for at least two years, can usually pass to the next generation with little or no inheritance tax, provided the assets are not investments and not surplus to the trade.

What Business Property Relief actually does

Inheritance tax in 2026/27 is charged at 40% on the value of an estate above the available allowances, which for most people means the nil-rate band of GBP 325,000 plus the residence nil-rate band of GBP 175,000. A reduced 36% rate applies where at least 10% of the net estate is left to charity. Without relief, a family business worth GBP 1 million could face a six-figure tax bill on death, often forcing a sale of the very thing the family wanted to keep.

BPR is the answer the tax system gives to that problem. Rather than exempting the business outright, it reduces the value that goes into the inheritance tax calculation. If a business qualifies for 100% relief, its value is effectively removed from the taxable estate. If it qualifies for 50% relief, half the value is removed. The relief is given automatically on a qualifying transfer, but the conditions are strict and the detail matters.

The two relief rates

There are two rates of relief, and which one applies depends on the type of property.

The headline cases are 100% relief on a sole trade, a partnership interest, or shares in an unquoted trading company. The 50% category is narrower and tends to catch assets used by a business but owned outside it - for example, a workshop you own personally that your trading company operates from.

The qualifying conditions

Three tests sit at the heart of BPR: ownership, trading and use.

The two-year ownership test

You must normally have owned the relevant business property for at least two years immediately before the transfer or the date of death. This stops people converting cash into business assets at the last moment purely to dodge inheritance tax.

There are limited exceptions. If you inherited the property from a spouse or civil partner, their ownership period can be added to yours. There are also rules for replacement property, where one qualifying business asset is sold and another bought, so that continuous business ownership is not broken by a sensible reorganisation.

The trading test

BPR is for trading businesses, not investment vehicles. A business does not qualify if it consists wholly or mainly of one or more of the following: dealing in securities, stocks or shares; dealing in land or buildings; or making or holding investments. In practice this is judged on the balance of the whole business, looking at turnover, assets, time spent and profit.

This is why a standard buy-to-let portfolio is normally excluded. Letting property for rent is treated as an investment activity, however much work the landlord puts in. Furnished holiday lets and businesses that provide substantial additional services sit in a grey area and are frequently refused relief, so do not assume property income qualifies.

The use test and excepted assets

Even where a business is broadly trading, relief is denied on so-called excepted assets - assets that are not used wholly or mainly for the business in the two years before the transfer, or that are not required for future use in the business. The classic examples are a large surplus cash balance well beyond working capital needs, and an investment property held inside an otherwise trading company.

The value of excepted assets is carved out of the relief. So a profitable trading company can still lose BPR on the slice of its value that represents idle investments. Keeping the balance sheet lean and trading-focused is part of good BPR planning.

A worked example

Suppose a single person dies in 2026/27 with an estate made up of a home worth GBP 400,000, savings of GBP 100,000, and shares in an unquoted trading company worth GBP 500,000 that they had owned for ten years.

The company shares qualify for 100% BPR, so their GBP 500,000 value drops out of the taxable estate entirely. That leaves GBP 500,000 of other assets. The nil-rate band of GBP 325,000 and the residence nil-rate band of GBP 175,000 together cover GBP 500,000, assuming the home passes to direct descendants and the estate is within the limits for the residence band.

In this example, BPR removes GBP 500,000 from the taxable estate. Combined with the two nil-rate bands, the inheritance tax bill falls to nil. Without the relief, the GBP 500,000 of shares would have sat on top of the allowances and been taxed at 40%, a charge of GBP 200,000.

How BPR interacts with other taxes

BPR is purely an inheritance tax relief. It does nothing for income tax, and it does not reduce capital gains tax.

For capital gains, the relevant reliefs are separate. On death there is generally a capital gains tax uplift to market value, so heirs inherit at the date-of-death value with no immediate CGT charge. If you instead sell or give away a business during life, you may face capital gains tax, where the 2026/27 rates are 18% within the basic-rate band and 24% above it, with Business Asset Disposal Relief charging qualifying gains at 18%. The annual exempt amount is GBP 3,000.

Because lifetime gifts and death transfers are taxed so differently, the right route depends on your wider plan. Model any disposal with our

before deciding, and keep IHT and CGT planning in separate columns.

Common traps to avoid

• Assuming buy-to-let qualifies. Investment letting is normally outside BPR, no matter how active the landlord.
• Sitting on surplus cash. Large idle balances inside a trading company become excepted assets and lose relief.
• Missing the two-year clock. Buying business assets shortly before death rarely works; the ownership test is unforgiving.
• Quoted shares. A minority holding in a listed company does not qualify; only a controlling stake attracts the 50% rate.
• Binding sale agreements. If there is a binding contract to sell the business at death, relief can be lost, so check shareholder and partnership agreements.

Where BPR fits in your estate plan

BPR is one of the most valuable inheritance tax reliefs available, but it rewards genuine, well-structured trading businesses rather than dressed-up investments. The practical takeaways are to hold qualifying assets for at least two years, keep the business trading and the balance sheet lean, and review structure regularly so excepted assets do not erode the relief.

For most families the relief works alongside the nil-rate bands, the spouse exemption and ordinary gifting. Start by estimating your exposure with our
