Inheritance Tax + April 2026 BR/APR Reform
UK Inheritance Tax (IHT) charges 40% on the value of an estate above thresholds at death, plus certain lifetime transfers within 7 years before death. **2025/26 thresholds**: **Nil-Rate Band £325,000** (frozen since 2009; Autumn Budget 2025 extended freeze to **April 2031**). **Residential Nil-Rate Band £175,000** (qualifying main home passing to direct descendants; tapers from £2m estate). **Spouse / civil partner exemption** unlimited; NRB + RNRB TRANSFERABLE to surviving spouse. **Combined family allowance**: married couple with main home can shelter up to £1 million (NRB+RNRB×2). **40% rate** above thresholds; **36% rate** where 10%+ of estate left to charity. **APRIL 2026 BR/APR REFORM (Finance Bill 2025-26)**: combined Business Relief + Agricultural Property Relief allowance CAPPED AT £2.5 MILLION per individual at 100% relief; above £2.5m, relief reduces to 50% (effective 20% IHT rate). Originally proposed at £1m (Autumn Budget 2024); revised to £2.5m after farming lobby pushback. **AIM SHARES**: from 6 April 2026, AIM-listed shares get FLAT 50% relief only (no access to the £2.5m 100% allowance). EIS shares on unlisted companies continue 100% BR within the cap. **APRIL 2027 PENSION REFORM**: unused pension funds + pension death benefits brought into IHT estate from 6 April 2027 (estimated 38,500 additional estates affected annually).

What this relief is, in plain English
UK Inheritance Tax is the wealth-transfer tax, charged primarily on estates above thresholds at death, plus certain lifetime transfers caught by the 7-year rule. The 2024-2026 reforms make IHT one of the most-changed areas of UK tax in recent years. **Core framework (2025/26):** - **NRB £325,000**: frozen since 2009; Autumn Budget 2025 extended freeze to April 2031. - **RNRB £175,000**: for main home passing to direct descendants; tapers from £2m estate. - **Spouse exemption unlimited**; NRB + RNRB transferable to surviving spouse on first death. - **40% rate** above thresholds; **36% rate** if 10%+ left to charity. - **Combined married couple shelter**: up to £1m via NRB + RNRB × 2. **April 2026 BR/APR £2.5m combined cap** is the largest IHT reform in decades. Pre-April-2026: unquoted trading company shares + qualifying farmland at 100% relief, no cap. Post-April-2026: £2.5m combined allowance at 100% relief; above £2.5m, 50% relief only (20% effective IHT). AIM shares moved to flat 50% (no 100% access). EIS shares on unlisted companies continue 100% within cap. **Spouse transferability**: £2.5m combined cap is transferable like NRB/RNRB. Married couple combined £5m of BR/APR-qualifying assets at 100% relief. Plus NRB/RNRB couple £1m. Plus margin = KPMG estimates ~£6.3m comprehensive shelter for substantial families. **Trust treatment** is more complex. Pre-30 October 2024 trusts holding BR/APR assets: each grandfathered with own £2.5m allowance for periodic + exit charges. Post-30 October 2024 trusts: share the settlor's £2.5m proportionately. **April 2027 pension reform**: unused pension funds + death benefits brought into IHT estate. ~38,500 additional estates affected annually. Major change to pension-as-estate-planning-vehicle position. **Lifetime gifting + 7-year rule**: gifts (PETs) become fully exempt if donor survives 7 years; taper relief from year 3 onwards (20%/40%/60%/80% reductions in years 4-7). Anti-avoidance: gifts with reservation of benefit (GWROB) treated as still in estate. **Non-dom reform April 2025**: domicile-based regime replaced by residence-based regime (10-year UK-residence test for IHT scope). Transitional rules for existing non-doms. For most middle-class estates (under £2.5m, owner-occupied home, modest BR/APR exposure), the practical IHT planning is: ensure spouse transferability mechanics used; structure main home to qualify for RNRB; consider lifetime gifting outside the 7-year window for substantial sums; maintain BR-qualifying business assets if applicable. For substantial estates (above £2.5m BR/APR + significant pension + main home + other wealth), specialist estate planning is essential from April 2026 onwards.
How it works
Nil-Rate Band + Residential Nil-Rate Band
NRB £325,000 per individual (frozen since 2009, extended to April 2031). RNRB £175,000 (qualifying main home + direct descendants; tapers from £2m estate at £1 per £2). Both transferable to surviving spouse / civil partner on first death. Combined married couple shelter: up to £1m (NRB+RNRB×2).
April 2026 BR/APR combined £2.5m cap
From 6 April 2026: combined Business Relief + Agricultural Property Relief at 100% capped at £2.5m per individual. Above £2.5m: 50% relief only (20% effective IHT). AIM-listed shares: FLAT 50% only (no 100% access). EIS shares on genuinely unquoted companies: 100% within cap. Spouse transferable: combined £5m couple. Cap refreshes every 7 years for individuals (lifetime gift purposes); CPI indexation from April 2031.
Lifetime gifting + 7-year rule + GWROB
Gifts during lifetime are Potentially Exempt Transfers (PETs), fully exempt from IHT if donor survives 7 years. Death within 7 years: PET becomes chargeable at NRB-adjusted basis. **Taper relief** in years 4-7 (20%/40%/60%/80% reductions to the IHT rate). **Gifts with Reservation of Benefit (GWROB)**: gifts where donor retains use / benefit treated as still in estate, anti-avoidance. **Annual exemption £3,000/year** of lifetime gifts (carry forward 1 year unused). **Small gifts £250 per recipient/year** exempt. **Normal expenditure out of income exemption** for regular gifts from after-tax income.
April 2027 pension reform + April 2025 non-dom reform
**April 2027**: unused pension funds + pension death benefits brought into IHT estate. Personal representatives report + pay. Excluded: death-in-service from registered schemes; DB dependant's scheme pensions. ~38,500 additional estates affected annually. **April 2025 non-dom reform**: domicile-based regime replaced with residence-based test (10-year UK-resident for IHT scope). Transitional rules for existing non-doms.
Who qualifies
- Death of UK-domiciled individual (pre-April 2025) or UK-resident individual under new residence test (post-April 2025)
- Personal representatives file IHT400 within 12 months of end of month of death
- Payment due 6 months after end of month of death (instalment options for illiquid assets)
- April 2026 BR/APR cap: applies to deaths on/after 6 April 2026 + lifetime gifts from 30 October 2024 if donor dies after 6 April 2026
- April 2027 pension reform: applies to deaths on/after 6 April 2027
Interactions with other reliefs
EIS Business Relief
EIS shares in unquoted trading companies continue 100% BR within £2.5m cap from April 2026. AIM-listed EIS shares: flat 50% from April 2026. See [[eis]] for full EIS lifecycle including IHT positioning.
BADR + Investors' Relief
BADR is CGT-side exit relief; IHT is estate-side death relief. Different mechanics + thresholds. BR/APR cap doesn't affect BADR mechanics directly. Owner-directors planning exit + estate jointly: BADR on lifetime exit; BR on retained ownership at death.
LSA + LSDBA + April 2027 pension reform
Pension lump sums regulated by LSA (£268k tax-free cash) + LSDBA (£1.073m broader). April 2027 brings unused pension wealth into IHT estate. Combined effect: substantial pension estates face materially more tax complexity from April 2027. See [[lsa]] + [[lsdba]].
Gift Aid + charitable bequests
10%+ of estate left to UK-registered charity reduces IHT rate from 40% to 36%. Substantial estates often optimise charitable bequests around this threshold. See [[gift-aid]] for lifetime charitable giving mechanics; charitable bequest mechanics similar at death.
Common mistakes + audit triggers
- Assuming pre-30 October 2024 PETs are grandfathered under old BR/APR rules (they're not, donor death from April 2026 applies new £2.5m cap to PETs from 30 October 2024 onwards)
- AIM share portfolios held as IHT planning vehicle without realising the April 2026 flat 50% switch
- Treating £2.5m cap as separate for BR + APR (it's COMBINED, single £2.5m pot covers both)
- Missing the 7-year refresh for individuals on the £2.5m cap (gift + die: gift counts toward cap; survive 7 years + new £2.5m available)
- Not using spouse transferability for combined £5m couple allowance
- Forgetting April 2027 pension reform when projecting estate IHT position
- Trust planning post-30 October 2024 expecting separate £2.5m per trust (post-Oct trusts share the settlor's £2.5m proportionately)
- Missing normal expenditure out of income exemption, substantial under-used relief
Worked example
John, Yorkshire - Unmarried Ltd Co founder with substantial BR-qualifying shares dies May 2027 (Death May 2027)
John dies 15 May 2027 (post-April-2026 BR/APR reform). Unmarried. Estate: £5,000,000 of unquoted trading company shares (held 5+ years, qualifying BR); £500,000 main home (passing to adult children); £200,000 other assets. No prior chargeable transfers. Full NRB + RNRB available.
Calculation: **Pre-April-2026 hypothetical (if died before 6 April 2026):** Unquoted trading company shares: 100% BR → £0 IHT on £5m. Main home £500k - RNRB £175k - NRB £325k = £0 chargeable. Other assets £200k absorbed within NRB / RNRB headroom. **Total IHT (pre-reform): £0.** **Post-April-2026 actual position (death May 2027):** Unquoted trading company shares £5m vs £2.5m BR cap. - First £2.5m at 100% BR → £0 IHT on this portion. - Remaining £2.5m at 50% BR → £1.25m chargeable (50% of £2.5m). - Main home £500k passes to adult children: RNRB £175k covers; £325k uses NRB. - Other assets £200k: NRB headroom exhausted by main home → £200k chargeable. **Total chargeable estate: £1,250,000 (BR excess) + £200,000 (other assets) = £1,450,000.** IHT at 40%: 0.40 × £1,450,000 = **£580,000.** **Charitable bequest scenario (10%+ to charity):** If John bequeathed £145,000 (10% of net chargeable) to UK charity: Rate reduces from 40% to 36%. IHT: 0.36 × (£1,450,000 - £145,000) = 0.36 × £1,305,000 = £469,800. **Saving: £110,200 in IHT, at a cost of £145,000 to charity**: net £34,800 cost for the £145,000 charitable gift. **Counter-factual: married couple position.** If John had been married + left estate to spouse: unlimited spouse exemption → £0 IHT on first death. On second death (spouse): combined £5m BR cap available + £1m NRB/RNRB couple = up to £6m at 100% relief. £5m business asset estate fits within £6m + £0 IHT. **Strategic implications:** 1. April 2026 reform makes unmarried + single substantial estates materially worse off than married estates. 2. Spouse transferability of the £2.5m cap is now the most important IHT planning mechanic for substantial business/farming families. 3. AIM share planning for IHT effectively ends April 2026 (50% flat relief only). 4. Lifetime gifting (7-year rule) plus £2.5m refresh every 7 years provides multi-cycle planning for very substantial estates. 5. Pre-30 October 2024 trusts grandfathered with full £2.5m each, substantial planning value for trusts established before that cliff date. 6. April 2027 pension reform: any unused pension wealth at John's death from April 2027 onwards also in estate. Personal representatives report + pay (not pension administrators). **Documentation + filing:** - IHT400 within 12 months of end of month of death. - IHT payment 6 months after end of month of death (instalment options for illiquid assets). - BR claim documented with company-level evidence (qualifying trade test, 50% non-trading-activity threshold, 2-year ownership). - Specialist tax + valuation adviser engagement essential for substantial estate IHT compliance.
