Business Relief & Succession
for your estate

Passing on a family business or a farm is one of the hardest parts of estate planning, and one of the most exposed to inheritance tax getting it wrong. Business Relief and Agricultural Relief have long allowed qualifying assets to pass largely free of inheritance tax, but the rules changed materially from 6 April 2026, when the 100% rate became capped at a combined GBP 1,000,000 per person, with 50% relief on qualifying value above that. For many business and farming families this turns a once-comfortable position into one that needs active planning.

Business succession planning is the work of structuring the handover so the business or farm passes to the next generation without a forced sale to pay the tax. That means confirming which assets qualify for relief, understanding how the new cap applies, valuing the business, and shaping ownership, gifting, and the will so the relief is preserved and the bill is one the family can meet. It joins inheritance tax planning, gifting, wills, and sometimes trusts into a single coordinated plan.

We connect business owners and farmers with accountants who specialise in succession and the reliefs, so the plan reflects the new cap and the family's commercial reality rather than an out-of-date assumption that everything passes tax-free. The accountant models the reliefs and the tax; the solicitor handles the legal documents. We make sure the specialist you reach actually works with these reliefs under the current rules.

Business Relief and Agricultural Relief are the two reliefs that have made it possible for trading businesses and working farms to pass down the generations without being broken up to pay inheritance tax. Business Relief applies to qualifying business assets such as shares in an unquoted trading company or an interest in a trading partnership; Agricultural Relief applies to the agricultural value of qualifying farmland and farm buildings. Both have historically given relief at up to 100%, which for many families meant the business or farm effectively passed free of inheritance tax. The reliefs are generous because Parliament did not want viable businesses and farms destroyed by a tax bill on the death of an owner.

From 6 April 2026 the position changed in a way every affected family needs to understand. The 100% rate of Business Relief and Agricultural Relief is now capped at a combined GBP 1,000,000 of qualifying value per person. Qualifying value above that GBP 1,000,000 ceiling receives relief at 50% rather than 100%, which means the excess is effectively taxed at half the normal rate. For an owner whose business or farm is worth well over GBP 1,000,000, this is a fundamental shift: assets that would have passed tax-free now generate a real liability, and that liability has to be funded from somewhere. Modelling the exposure under the new cap is the starting point for any current succession plan.

Eligibility is not automatic, and confirming it is the first technical task. Business Relief generally requires the business to be trading rather than mainly an investment business; companies and partnerships whose activity consists wholly or mainly of holding investments, dealing in securities, or letting land typically do not qualify. The assets usually have to have been owned for at least two years before the transfer. Agricultural Relief applies to the agricultural value of land occupied for agriculture, with ownership and occupation conditions that depend on whether the owner farmed it themselves or let it. Excepted assets within a business, surplus cash, and investment property held inside an otherwise trading company can all reduce the relief, so a clear-eyed review of what genuinely qualifies has to come before any plan is built.

Lifetime transfers are a central tool in succession, and they interact with the reliefs and the seven-year rule. Gifting shares in a trading company or an interest in a farm to the next generation during life can remove future growth from the estate and start the seven-year clock, and Business or Agricultural Relief can apply to the lifetime transfer where the conditions are met. But the relief at death on a lifetime gift can be lost if the recipient no longer owns the asset, or it no longer qualifies, at the date of death within the seven years. Sequencing lifetime gifts, retaining the right controls, and ensuring the asset stays qualifying are all part of the structuring, and getting them wrong can forfeit the very relief the plan relied on.

The will and the ownership structure decide whether the relief actually lands where intended. Leaving a qualifying business to a spouse uses the spouse exemption but can waste the deceased's relief, since the spouse exemption would have covered the transfer anyway; in some cases leaving qualifying assets to the next generation directly makes better use of the relief. Fragmenting a business across several beneficiaries, or leaving qualifying and non-qualifying assets in the wrong proportions, can undermine both the relief and the viability of the business. The will has to direct the business deliberately, which is why succession planning and estate structuring are done together, with the accountant modelling and the solicitor drafting.

Finally, the plan has to solve for funding the tax that does arise, because the whole purpose is to avoid a forced sale. Inheritance tax attributable to qualifying business assets and to land can often be paid by ten annual instalments, which spreads the cost and can in some cases be interest-free for the business element, easing the pressure on cash flow. Life insurance written in trust is a common way to provide a lump sum outside the estate to meet the bill. With the new cap creating real liabilities for larger businesses and farms, planning the funding route is no longer optional, and a specialist builds it into the succession plan from the outset rather than leaving the next generation to find the money.

Mixed businesses that combine genuine trading with significant investment activity are the area where Business Relief is most often lost. A company that trades but also holds substantial let property or a large investment portfolio can fail the wholly-or-mainly-trading test, and excepted assets such as surplus cash beyond the business's needs are stripped out of the relief even where the company qualifies overall. A specialist examines the balance sheet and the activities closely, because an owner who assumes the whole company qualifies can find on death that a large part of its value is fully taxable. Restructuring the business to protect the trading status is sometimes part of the plan.

The new GBP 1,000,000 cap from 6 April 2026 changes how couples should structure ownership, because the cap is per person. A business owned entirely by one spouse can access only that spouse's GBP 1,000,000 of 100% relief, whereas splitting qualifying ownership across both spouses can, with care, allow each to use their own cap. This kind of ownership planning has to respect the commercial reality of the business and the other tax consequences of transferring shares, but for larger family businesses it can make a substantial difference to the relief available across two deaths. It is precisely the modelling a specialist does under the current rules.

Farms present their own complications because Agricultural Relief covers only the agricultural value of the land, not any additional development or hope value, and not necessarily the farmhouse unless it is of a character appropriate to the holding. Diversified farms with holiday lets, solar arrays, or other non-agricultural enterprises may find parts of the business qualify for Business Relief, parts for Agricultural Relief, and parts for neither, each now subject to the combined GBP 1,000,000 cap. Untangling which relief applies to which asset, and how the cap is shared, is detailed work that a specialist in farming succession is equipped to handle.

Lifetime gifts of business assets can backfire if the conditions are not maintained for the full seven years. Where an owner gifts shares to a successor and then dies within seven years, the relief available at death depends on the successor still owning the asset and it still qualifying at that point. If the successor has sold the shares, or the company has ceased to trade, the relief can be lost and the gift becomes fully chargeable. The structuring therefore has to include conditions and understandings about retaining and continuing to qualify the asset, and a specialist tracks the position through the survival period rather than treating the gift as the end of the job.
