Business Property Relief (BPR): Passing On Your Trade Business and Inheritance Tax — UK Guide 2026

What Is Business Property Relief?

Inheritance Tax (IHT) is charged at 40% on the value of an estate above the available nil-rate bands when someone dies, and it can also apply to certain lifetime gifts. For a trade business owner, the value tied up in the business can easily push an estate well over the threshold — but the business itself is usually not something you can sell a slice of to raise cash.

Business Property Relief solves this. It reduces the value of qualifying business assets passed on — whether on death or by a lifetime gift — by either 100% or 50% for Inheritance Tax purposes. Where 100% relief applies, the qualifying business value effectively passes free of IHT, so the business can continue under the next generation without being broken up to fund a tax bill.

BPR is not something you claim during your lifetime to reduce your own tax. It applies when the business or business asset is transferred — typically on death, but also on a lifetime gift into trust or to an individual. It is assessed against the value of the asset at the point of transfer.

What Qualifies — and at What Rate

The relief rate depends on the type of asset. For most trade business owners, the headline rates break down like this.

100% Relief

100% Business Property Relief applies to:

• An unincorporated trading business, or a share in one. This covers a sole trader trade and a partner's share in a trading partnership — so most self-employed tradespeople and trade partnerships fall here.
• Unquoted (private) company shares. Shares in a private limited company that runs a trading business qualify — including the family Ltd that runs your trade. Shares quoted on a recognised stock exchange generally do not qualify, but shares on AIM and other unlisted markets are treated as unquoted.

In practice this means the great majority of trade businesses — the sole trader trade, the partnership share, and the shareholding in a family trading company — sit in the 100% relief category.

50% Relief

50% Business Property Relief applies to certain assets owned personally rather than by the business itself, in particular:

• Land, buildings, plant or machinery you own personally but which is used in the trade of a partnership you are a partner in, or a company you control.

A common example: you own the yard, workshop or industrial unit personally, but your trading Ltd company (which you control) operates from it. The premises can attract 50% relief even though the company occupies it. This is also why ownership structure matters — holding a trading premises personally outside the company can leave it on a lower relief rate than the trading business itself.

The Conditions You Have to Meet

1. The 2-Year Ownership Period

You must have owned the business or the asset for at least two years before the transfer. A business you started or bought into less than two years before death will not qualify (there are limited exceptions, for example where assets replace earlier qualifying business property, or where property passes between spouses). The two-year rule is why succession planning needs to start early — relief is not available on something acquired at the last minute.

2. The Business Must Be Mainly Trading

This is the condition that catches people out. BPR is a relief for genuine trading businesses, not investment vehicles. A business does not qualify if it consists wholly or mainly of:

• making or holding investments;
• dealing in securities, stocks or shares;
• dealing in land or buildings; or
• letting property (a property-rental or buy-to-let business).

The test is "wholly or mainly" — HMRC looks at the business as a whole, in the round, across factors such as turnover, profit, asset value, time spent and the overall nature of the activity. A property-letting business generally does not qualify for BPR. A straightforward trade — fitting bathrooms, wiring houses, building extensions — is plainly trading and qualifies. The grey areas are mixed businesses: a trade that has accumulated a portfolio of rental units, or that holds large surplus investments, can find part or all of its relief at risk.

3. Watch the "Excepted Assets"

Even where a business qualifies, relief does not extend to excepted assets — assets that were neither used wholly or mainly for the business in the two years before the transfer, nor required for future use in the business. The classic example is a large pile of surplus cash sitting in the company that goes well beyond what the trade needs as working capital, or an investment property held inside the trading company. Those excepted assets are carved out of the relief and remain exposed to IHT, even though the trade around them qualifies. Keeping the balance sheet lean and trade-focused matters.

The Big 2026 Reform — a £1m Cap on 100% Relief

This is the single most important change for any owner of a larger trade business, and it is why succession planning cannot wait. From 6 April 2026, the government is reforming Agricultural Property Relief and Business Property Relief together.

Under the reform, 100% relief is capped at a combined £1 million of qualifying agricultural and business assets per person. Qualifying value above that £1 million threshold drops to 50% relief rather than 100%. Because IHT is charged at 40%, 50% relief on the excess works out as an effective 20% Inheritance Tax charge on qualifying business value over £1 million.

For a sole trader trade or a family Ltd worth well under £1m, the practical effect is limited — most qualifying value still gets full relief. But for owners of larger trade businesses — a substantial contracting firm, a multi-van operation with valuable premises, a business that has grown well into seven figures — the excess over £1m now carries a real tax cost on succession. That changes the maths on whether to gift earlier, how to structure ownership across spouses and family, and whether life cover is needed to fund the eventual bill. The £1m allowance is per individual, so spreading ownership and using both spouses' allowances becomes more valuable. If your business is anywhere near or above £1m, get advice ahead of the April 2026 changes rather than after.

How BPR Interacts With the Nil-Rate Bands and CGT

BPR sits alongside the standard Inheritance Tax allowances. Every individual has a nil-rate band (the tax-free slice of an estate), and there is an additional residence nil-rate band where a main home passes to direct descendants. BPR reduces the value of the qualifying business before the nil-rate bands are applied to the rest of the estate, so the two work together — relief on the business, then allowances against the remaining estate.

Lifetime gifts add another layer. If you give the business away during your lifetime, BPR can apply to the gift, but there is also Capital Gains Tax to consider, because a gift is treated as a disposal at market value for CGT. Hold-over (gift) relief can often be claimed on a gift of qualifying business assets, which defers the CGT by passing the base cost to the person receiving the gift rather than triggering a charge on the transfer. The interaction between IHT, BPR, CGT and hold-over relief on a lifetime gift is genuinely complex — it is one of the clearest cases for taking professional advice before acting.

Planning Points for Trade Business Owners

• Start the ownership clock early. The two-year rule means relief is only available on a business or asset held for at least two years before the transfer. Bring family members into ownership well ahead of time, not at the last minute.
• Keep the business trading. Don't let investment activity — surplus cash, rental properties, share portfolios held in the company — grow to the point where the "wholly or mainly trading" test is threatened. A trade that drifts into being mainly an investment business loses the relief.
• Watch excepted assets. Large cash balances or non-trading assets sitting in the company can be carved out of relief. Distribute or deploy surplus cash, and avoid parking unrelated assets inside the trading entity.
• Review ownership structure. Premises held personally may only get 50% relief, while the trade gets 100%. Consider how property is held, and use both spouses' £1m allowances after April 2026.
• Consider life cover. Where the 2026 cap or non-qualifying assets leave a likely IHT bill, a life insurance policy written into trust can provide the cash to pay it without forcing a sale of the business.
• Get advice ahead of April 2026. The £1m cap materially changes succession planning for larger trade businesses. A solicitor or tax adviser specialising in estate planning can model your position before the rules change.
