Business Relief, once called Business Property Relief, reduces the inheritance tax due on qualifying business assets by 50% or 100%. It covers trading businesses, unquoted shares and some AIM-listed shares held for at least two years. From April 2026 the 100% relief is capped at £1 million per person, with 50% above that.
The short answer
- Business Relief reduces the value of qualifying business assets for inheritance tax by 50% or 100%.
- Trading businesses and unquoted shares can qualify; investment businesses generally do not.
- Assets normally have to be held for at least two years to count.
Business Relief, still often called Business Property Relief, or BPR, is one of the most valuable reliefs in the inheritance tax system. It reduces the taxable value of qualifying business assets by either 50% or 100%, meaning a family firm or a stake in a trading company can, in the right circumstances, pass down the generations with little or no inheritance tax to pay. It exists so that heirs are not forced to break up or sell a working business simply to settle a tax bill.
How Business Relief works
The relief works by cutting the value of the qualifying asset when the estate is added up. If an asset qualifies for 100% relief, its whole value drops out of the inheritance tax calculation; if it qualifies for 50%, half does. To count, the assets must generally have been owned for at least two years before death, and the business must be genuinely trading rather than mainly holding investments, a company that simply owns property to let, for instance, usually does not qualify.
Business Relief rates (2026)
| Asset | Relief |
|---|---|
| A sole trader business or share in a partnership | 100% |
| Unquoted (private) company shares | 100% |
| Shares listed on AIM | 50% (from April 2026) |
| A controlling holding in a fully listed company | 50% |
| Land, buildings or machinery used by your business | 50% |
What qualifies, and what does not
The dividing line is whether the business is trading or investing. HMRC denies relief to businesses that are “wholly or mainly” engaged in dealing in securities, stocks or shares, land or buildings, or holding investments. That excludes most buy-to-let portfolios and share-dealing companies. Our full guide to Business Relief works through the tests, and it sits alongside the wider toolkit in our guide to reducing inheritance tax legally.
- Trading businesses, manufacturing, retail, services and the like, generally qualify;
- Investment businesses such as buy-to-let landlords and holding companies usually do not;
- The assets must normally have been held for at least two years;
- Cash or assets held well beyond the trade’s needs (“excepted assets”) can be stripped out of relief.
The April 2026 changes
Business Relief is less unlimited than it once was. From April 2026, the 100% rate is capped: each person has a combined £1 million allowance covering business and agricultural property together, and anything above that receives 50% relief rather than 100%. Separately, shares listed on AIM, long a popular inheritance tax planning tool, move from 100% relief to 50%. These are significant changes for larger business estates, and they make forward planning more important than before.
For most family business owners the £1 million allowance will still cover the whole value, so nothing changes. It is larger estates, successful trading companies, sizeable farms and substantial AIM portfolios, that feel the effect, and for them the reforms can turn a nil inheritance tax bill into a real one on death. Because the changes reward spreading qualifying assets across a couple and planning succession early, many owners are revisiting their wills, shareholder agreements and gifting strategies well ahead of time rather than leaving it to chance.
A relief, not a guarantee
Business Relief depends on the business still qualifying at the date of death, circumstances, and the rules themselves, can change. It is genuinely valuable but should never be the only string to your bow, and this is information, not personal advice.
How it fits with agricultural property
Business Relief has a close cousin, Agricultural Property Relief (APR), which works in a similar way for farmland and farm buildings that are actively farmed. The two reliefs often overlap on a working farm: the land may attract APR while the farming business and its machinery attract Business Relief, and from April 2026 they share the same combined £1 million allowance for 100% relief. For farming and estate-owning families in particular, that shared cap makes it far more important to understand which assets fall under which relief, and to plan ownership between spouses so that both £1 million allowances can be used rather than wasted. A married couple who each hold qualifying assets can, between them, shelter up to £2 million at the 100% rate before the 50% band begins.
Using it in your planning
Because qualifying assets can attract up to 100% relief, Business Relief is a cornerstone of planning for business owners, and through specialist BPR-qualifying investment portfolios, for some who simply want their money to fall outside inheritance tax after two years rather than the seven years a lifetime gift requires. But these investments carry real risk: smaller and unquoted companies can be volatile and hard to sell, and investments can fall as well as rise.
