IHT When Selling a Business UK: Inheritance Tax After a Business Sale and What to Do with the Proceeds (2026)
Selling your business destroys Business Property Relief — converting a BPR-protected asset into cash that is fully subject to 40% IHT. BADR reduces your CGT to 14–18% on the gain but does nothing for IHT. This guide explains the IHT consequences of a business exit and the planning options available from day one.
| Scenario | CGT | IHT (net estate) | Net to family |
|---|---|---|---|
| Die holding business (£2m, 100% BPR, pre-Apr 2026) | £0 | £0 | £2,000,000 |
| Sell for £2m (BADR, base cost £200k) then die with cash | ~£252,000 | ~£590,000 | ~£1,158,000 |
| Sell + gift £1m immediately as PET + survive 7yr | ~£252,000 | ~£190,000 (on £800k+) | ~£1,558,000 |
| Sell + reinvest £1.5m in AIM BPR shares (2yr hold) | ~£252,000 | ~£90,000 (on £500k above NRB) | ~£1,658,000 |
| Illustrative figures only — assumes NRB £325k, BADR rate 14%, no other reliefs. Net to family = business proceeds after CGT and IHT. BADR CGT: 14% on gain above £200k base cost = 14% × £1.8m = ~£252k. Figures rounded. | |||
IHT After a Business Sale: What You Need to Know
How selling a business destroys Business Property Relief
Business Property Relief (BPR) under ss105–114 IHTA 1984 provides 100% relief on the value of qualifying business property in the IHT estate. While a business owner holds qualifying shares in an unquoted trading company or a sole trader business, those assets can pass to beneficiaries free of IHT (subject to the £1m cap from April 2026). The moment the business is sold, BPR is lost. The sale proceeds — whether cash, listed shares, gilts, or any other non-qualifying asset received on exit — are fully within the IHT estate with no BPR. A business owner who sells their company for £2m and then dies holding the cash faces: IHT on £2m (less NRB of £325,000 and any other reliefs) at 40% = approximately £670,000 in IHT. Had the same owner died while still holding the shares (assuming 100% BPR on the full £2m under pre-April 2026 rules), the IHT would have been nil. The business sale transforms a BPR-protected asset into a fully taxable estate asset — creating an IHT problem that did not previously exist. This is sometimes called 'the BPR cliff edge': owners who expect to sell should plan the deployment of sale proceeds long before the sale completes.
Business Asset Disposal Relief (BADR): CGT on the sale
When a business owner sells their qualifying company shares or business, they may qualify for Business Asset Disposal Relief (BADR — formerly Entrepreneurs' Relief) which reduces the CGT rate on qualifying gains: from April 2025, the BADR rate is 14% (reduced from 20% in the Budget 2024); from April 2026, the BADR rate increases to 18% (remaining below the standard 18%/24% rates for non-BADR gains). The lifetime BADR limit is £1,000,000 of qualifying gains per individual — gains above £1m are taxed at the standard CGT rate. BADR applies to: disposals of qualifying business assets (5%+ shareholding in a personal company held for 2+ years); sole trader and partnership business disposals. BADR reduces CGT to 14–18% on qualifying gains — but it does not affect IHT. The sale proceeds are still fully in the IHT estate. A successful exit involves both a low CGT bill (BADR) and a plan for the IHT exposure created by cash proceeds.
Dying holding vs. selling: the BPR cliff edge
For business owners considering a sale, the comparison between dying while holding the business (BPR) and selling and then dying with cash is stark. Example: a 65-year-old owns 100% of a company worth £2m. Option A — dies while holding (no sale): IHT under pre-April 2026 rules = nil (100% BPR). Net to beneficiaries: £2m. Option B — sells for £2m, then dies 3 years later holding cash: CGT at 14% (BADR) on the gain from base cost = say £300,000 on a £300k gain from original cost of £1.7m. Cash estate = £2m × 0.86 (after BADR CGT) = approx. £1.7m in cash. IHT on cash: 40% × (£1.7m − £325k NRB) = £550,000. Net to beneficiaries: ~£1.15m. The difference: approximately £850,000 less for the family as a result of selling vs. dying holding. This is an extreme case (assuming full BPR, which may be capped post-April 2026) — but it illustrates why selling a business has very significant IHT consequences that must be planned for. Many business owners are surprised to discover that the sale which was supposed to secure their family's future has created an IHT liability that did not previously exist.
Planning option 1: lifetime gifts from sale proceeds as PETs
Cash gifted to children, grandchildren, or other individuals during the seller's lifetime is a potentially exempt transfer (PET): survive seven years, the gift is fully exempt from IHT. There is no cap on the amount of a PET. Staggered gifting: immediately after the sale (and BADR/CGT payment), begin a programme of substantial annual gifts — both as PETs and using the £3,000 annual exemption plus normal expenditure from income. If the donor survives seven years from any particular gift, that gift falls entirely outside the estate. This can progressively reduce the IHT exposure of the estate from sale proceeds. Note: even if the donor does not survive seven years, taper relief applies after three years (rates from 32% down to 8% over years 3–7). The sooner gifting begins after the sale, the sooner the seven-year clock starts running. The timing of the sale itself matters: selling earlier in life (say at 60) gives a better chance of surviving seven years than selling at 80.
Planning option 2: reinvesting in BPR-qualifying assets
Sale proceeds can be reinvested into assets that attract BPR in their own right — meaning the BPR clock starts running again on the new investment. The most accessible BPR-qualifying reinvestment options are: (1) AIM shares in qualifying trading companies: shares on AIM in companies that are 'wholly or mainly' trading attract 100% BPR under s105(1)(bb) IHTA 1984. Two-year holding period required. AIM share portfolios specifically targeted at BPR-eligible companies are available from investment managers. (2) Enterprise Investment Scheme (EIS) shares: EIS shares in qualifying trading companies are unquoted and attract BPR if held for two years in qualifying circumstances. EIS also offers CGT deferral (reinvestment relief) and 30% income tax relief on the subscription. (3) Seed EIS (SEIS) shares: similar BPR-qualifying treatment for SEIS shares in early-stage companies. Risks: AIM, EIS, and SEIS are higher-risk investments — growth companies and start-ups. The IHT benefit must be balanced against investment risk. From April 2026, the £1m BPR/APR cap means that BPR on AIM/EIS reinvestment above £1m attracts only 50% relief.
Planning option 3: pension contributions from sale proceeds
Pension contributions from sale proceeds provide a tax-efficient holding structure for cash. A personal pension or SIPP contribution: attracts income tax relief at the donor's marginal rate (up to the annual allowance — £60,000 per year for 2024/25 and beyond, or up to net relevant earnings); the pension fund grows free of CGT and income tax; until April 2027, the pension pot is outside the IHT estate (pension scheme assets are generally in discretionary trust with the scheme trustees having discretion on death benefits — not estate assets for IHT). From April 2027, however, pension pots will be brought into the IHT estate. The window between a business sale and April 2027 is therefore a uniquely valuable opportunity: contribute to a pension now, the funds are outside the IHT estate, grow tax-free, and (until April 2027) pass to beneficiaries free of IHT under the scheme's discretionary trust. The annual allowance and carry-forward rules limit the total contribution per year — a specialist tax adviser can model the optimal contribution sequence.
Planning option 4: life insurance in trust
Rather than (or in addition to) reducing the estate, business owners can fund the IHT liability directly through a life insurance policy written in trust. A whole-of-life policy pays a lump sum on death, outside the estate (because it is held in trust), which the trustees can use to pay the IHT bill — leaving the sale proceeds intact for beneficiaries. The lump sum matches the estimated IHT liability: for example, if £2m in cash is expected to generate approximately £670,000 in IHT (after NRB), a whole-of-life policy with a £670,000 sum assured funds the tax. Monthly premiums paid from income can qualify as normal expenditure from income (s21 IHTA 1984) — themselves exempt from IHT. The policy is arranged before or immediately after the sale — premiums for older sellers or those with health issues are higher, making it important to arrange cover sooner rather than later.
Estate freeze and family governance before the sale
The best IHT planning for a business sale happens before the sale completes. Once the business has been sold and the cash received, the options narrow: PETs require survival of seven years, reinvestment requires time to accumulate the two-year BPR clock, and pension contributions are capped annually. Before the sale: (1) Gift shares to family members before the sale completes — the gift value is the pre-sale share value (lower than post-sale cash); the PET starts the seven-year clock; the recipient receives the sale proceeds rather than shares (with CGT potentially deferred via gift relief, though this is complex in a sale context). (2) Use an Employee Ownership Trust (EOT) if the business will be sold to employees — EOT sales are CGT-exempt and create a charitable-trust-like structure that can shelter IHT on the deferred consideration. (3) Structure earn-out consideration thoughtfully — future earn-out may attract BPR if structured as a deferred business payment rather than a debt in the estate. These pre-sale strategies require careful advice — once the sale has completed, the most powerful options are no longer available.
Frequently Asked Questions
What happens to Business Property Relief when I sell my company?
Business Property Relief (BPR) is lost on sale. The moment your company shares are sold and you receive cash (or other non-qualifying assets), the BPR that would have applied to the shares no longer protects the sale proceeds. Cash in your estate is fully subject to IHT at 40% above the NRB — there is no BPR on cash. To re-qualify for BPR on the proceeds, you must reinvest in qualifying assets (AIM shares, EIS shares, another business) and hold them for at least two years before your death.
Is there IHT on business sale proceeds?
Yes. Business sale proceeds held as cash at death are fully included in the IHT estate at their face value, with no Business Property Relief. BADR (Business Asset Disposal Relief) reduces CGT on the gain at sale to 14–18% — but it has no effect on IHT. Planning is essential: begin PETs to family members immediately; consider reinvestment in BPR-qualifying AIM or EIS shares; fund pensions; take out life insurance in trust to cover the IHT bill.
Can I avoid IHT by reinvesting my business sale proceeds into EIS or AIM shares?
Reinvesting into qualifying AIM shares or EIS shares in trading companies can re-qualify for 100% BPR after a two-year holding period. The investment must be in qualifying assets and must be maintained for two years before death for BPR to apply. From April 2026, the £1m combined BPR/APR cap means that BPR on AIM/EIS reinvestment above £1m attracts only 50% relief. AIM and EIS investments are higher-risk — the IHT benefit must be balanced against investment risk.
What is the best thing to do with business sale proceeds to reduce inheritance tax?
No single strategy fits all situations, but the most common actions are: (1) Start substantial PETs (gifts to children/grandchildren) immediately — the 7-year clock starts on each gift; (2) Reinvest in BPR-qualifying AIM or EIS shares (2-year holding period required); (3) Contribute to a pension up to the annual allowance — outside the IHT estate until April 2027; (4) Life insurance in trust to fund the IHT bill; (5) Use annual exemptions (£3,000/year) and normal expenditure from income. Begin planning before the sale completes if possible — the window for the most effective strategies closes once cash is in hand.
Is it better to die holding the business shares or sell and then manage IHT?
If BPR fully applies (pre-April 2026 rules, below the £1m cap), dying while holding qualifying business shares can eliminate IHT entirely — whereas selling creates cash that is fully subject to 40% IHT. Post-April 2026, BPR above £1m is capped at 50% relief (effective 20% IHT). The comparison depends on: BPR cap impact; your realistic life expectancy; BADR CGT rate on sale; ability to deploy proceeds into BPR-qualifying replacements; pension contribution capacity. For most business owners, dying holding is IHT-optimal — but real-life reasons to sell (retirement, family, commercial pressures) mean that post-sale IHT planning is often unavoidable.
Update Your Will After Your Exit
After a business sale, your estate profile changes dramatically — BPR assets become cash; beneficiary needs may shift; life insurance trusts may need updating. Your will should reflect the new estate. WillSafe will kits for England and Wales make it easy to update your wishes and ensure your estate plan keeps pace with your financial life.
