Partnership Assets and BPR: Inheritance Tax on Partnership Interests UK (2026 Guide)
An equity partner's interest in a trading partnership qualifies for 100% Business Property Relief under IHTA 1984 s105(1)(a). From April 2026, the combined BPR and APR cap is £2.5m per person — partnership interests above the cap attract 50% BPR (20% effective IHT). Excepted assets, salaried partner status, and LLP members are key considerations.
BPR Qualifying Status by Type of Partnership Interest
| Type of Interest | Qualifying? | Key Caveats |
|---|---|---|
| Interest in a partnership (equity partner) | Yes — 100% BPR under IHTA 1984 s105(1)(a). An equity interest in a business carried on as a partnership. | Must be a genuine equity partnership, not a salaried arrangement. The deceased must have held the interest for at least 2 years before death. |
| LLP member's interest | Yes — treated the same as a partnership for BPR purposes after the Partnership Act 2000 changes. | Salaried LLP members (fixed-salary, no capital at risk, no significant influence) may not qualify — HMRC may treat them as employees rather than partners. |
| Shares in a partnership trading company | Yes — unquoted shares in a company that is a member of a trading group qualify for 100% BPR under s105(1)(bb). | The April 2026 £2.5m cap applies across all 100% BPR assets. |
| Excepted assets (investments, surplus cash) | No — the proportion of the partnership's net asset value attributable to excepted assets is excluded from BPR. | HMRC identifies excepted assets on the partnership balance sheet: investment properties held by the partnership, surplus cash not required for the business, securities/quoted investments held by the partnership. |
| Agricultural land held by partnership | APR may apply to agricultural land — same 2-year holding period rules. | APR and BPR share the same £2.5m 100% relief cap from April 2026. If the partnership holds both trading assets (BPR) and agricultural land (APR), the combined value is tested against the cap. |
| Capital account balance | The capital account (the partner's share of net assets) is the basis for BPR valuation. | BPR applies to the net value of the interest, reduced for excepted assets. A partnership with large investment property holdings held outside the trading business may have significant excepted assets reducing BPR. |
Partnership IHT Planning Post-April 2026
For partners whose capital account exceeds £2.5m, the most effective planning steps are:
First, use both spouses' £2.5m caps if both spouses hold qualifying assets. A senior partner with a £4m capital account could transfer £1.5m of the interest (or other equivalent qualifying assets) to their spouse. Inter-spousal transfers are IHT-free and CGT-neutral. The couple then each has £2.5m within the 100% BPR threshold.
Second, consider whether any partnership assets are excepted assets that could be restructured. Surplus cash held in the partnership that exceeds genuine working capital requirements is an excepted asset — returning it to partners as drawings (which they then hold personally) reduces the excepted asset proportion and increases the BPR-qualifying fraction.
Third, a lifetime gift of a partnership interest (with holdover relief under TCGA 1992 s165 available on qualifying business assets) removes the asset from the estate. The donee inherits the deferred CGT gain but the IHT clock starts from the date of gift — if the donor survives 7 years, the transfer is fully outside the estate.
Frequently Asked Questions
Does a partnership interest qualify for Business Property Relief?
Yes — an equity partner's interest in a qualifying business carried on as a partnership qualifies for 100% BPR under IHTA 1984 s105(1)(a). The partnership must be a trading partnership (carrying on a trade or profession), not an investment partnership (which merely holds investments). The 2-year minimum ownership period applies: the deceased must have held the partnership interest for at least 2 years immediately before death. From April 2026, the combined 100% BPR and APR is capped at £2.5 million per person. A partnership interest worth £1.5m falls within the cap and attracts 100% BPR — nil IHT. A partnership interest worth £4m: the first £2.5m attracts 100% BPR (nil IHT); the remaining £1.5m attracts 50% BPR (effective IHT of 20%, so £300,000 IHT). BPR only applies to the partnership's trading assets — 'excepted assets' (investment property, surplus cash, non-trading investments) within the partnership are excluded from relief and taxed at the full 40% rate.
What are excepted assets and how do they reduce BPR on a partnership interest?
Excepted assets under IHTA 1984 s112 are assets in a business that are not used wholly or mainly for the purposes of the business throughout the 2 years before death (or throughout the period of ownership if shorter). For a partnership, excepted assets typically include: (1) investment properties held by the partnership that are not used in the trade; (2) quoted investments, portfolio funds, or listed shares held by the partnership; (3) surplus cash — cash reserves beyond what is needed for the working capital of the business. The BPR available is reduced pro rata by the proportion of the partnership's net asset value that consists of excepted assets. Example: a partnership has a net asset value of £2m. Of this, £400,000 is surplus cash that is not needed for the trading business (an excepted asset). The excepted assets proportion is 20%. BPR applies to 80% of the partnership interest value, not 100%. The excepted 20% is taxable at 40% IHT. To minimise excepted assets, partnerships should hold only working capital cash and ensure investments are genuinely held for business purposes.
Are salaried partners entitled to BPR on their partnership interest?
A salaried partner — one who receives a fixed salary rather than a share of profits, has no capital at risk, and has no significant say in management — may not qualify for BPR. HMRC takes the view that a salaried partner is, in substance, an employee of the partnership, not a true equity co-owner of the business. BPR requires the transfer to be of a business or interest in a business (IHTA 1984 s103). If the 'partner' is effectively an employee, they do not have an equity interest in the business — they have an employment contract. For professional firms (law firms, accountancy practices), this distinction is important: junior partners who are classified as salaried for profit-share purposes but who do have capital accounts, take on genuine capital risk, and participate in management may still qualify. The specific terms of the partnership agreement and the economic reality of the arrangement are determinative. Obtaining specialist tax advice before assuming BPR applies is strongly recommended for salaried partners.
Does a Limited Liability Partnership (LLP) interest qualify for BPR?
Yes — the interest of an equity member in a limited liability partnership qualifies for 100% BPR under IHTA 1984 s105(1)(a) in the same way as an ordinary partnership interest, provided the LLP carries on a qualifying trade or profession. LLPs were introduced by the Limited Liability Partnerships Act 2000. For IHT and BPR purposes, HMRC treats LLP members as partners in a partnership. The key conditions are the same: (1) 2-year minimum holding period; (2) the LLP must be carrying on a qualifying business (not purely investment); (3) excepted assets reduce the BPR proportionally. From April 2026, the £2.5m cap applies across all 100% BPR assets including LLP interests. A salaried member of an LLP (under the salaried member rules introduced in Finance Act 2014) faces the same analysis as a salaried partner in an ordinary partnership: if the member is effectively an employee, BPR may not apply.
How is a partnership interest valued for IHT?
A partnership interest is valued at the open market value at the date of death under IHTA 1984 s160 — the price a willing buyer would pay to a willing seller. For a partnership interest, the starting point is the capital account balance (the partner's share of the partnership's net assets as shown in the partnership balance sheet). The market value may differ from the capital account balance: (1) goodwill that is not on the balance sheet may be a significant element of value — particularly for professional practices or client-relationship businesses. HMRC will expect goodwill to be included in the valuation if it is a real element of the business value. (2) A minority interest may attract a minority discount, as a partial interest in a partnership is harder to sell and the buyer cannot control the business. (3) The partnership agreement may restrict the transferability of interests (many partnership agreements require consent from other partners for a transfer) — this may affect the open market value. The net value after deducting excepted assets is the BPR-qualifying value. The excepted assets are valued separately and included in the taxable estate at full value.
Does the April 2026 BPR cap affect large partnership interests?
Yes — from 6 April 2026, the combined 100% BPR and APR is capped at £2.5 million per person. Partnership interests above £2.5m (combined with any other 100% BPR or APR assets) attract only 50% BPR (effective IHT of 20%). For large professional partnerships (law firms, accountancy practices, medical partnerships), partner capital accounts can be substantial. A senior partner with a capital account of £4m: (1) First £2.5m: 100% BPR — nil IHT. (2) Remaining £1.5m: 50% BPR — taxable value £750,000. After the NRB (£325,000), IHT of £170,000. Planning: each spouse has their own £2.5m cap. If the partner's spouse or civil partner also holds a partnership interest or other qualifying business assets, both can claim 100% BPR on up to £2.5m each. Lifetime gifts of a partnership interest to the next generation are PETs and remove the asset from the estate if the donor survives 7 years — though holdover relief under TCGA 1992 s165 may be available to defer CGT on the gain.
