The NRB freeze until 2030 is a stealth IHT increase — 400,000 more estates expected to pay IHT by 2030
The nil rate band has been frozen at £325,000 since April 2009 — and the Autumn Budget 2024 extended this freeze until April 2030. With UK house prices rising significantly over this period, many more estates are pulled into IHT each year without any rate change. HMRC estimates approximately 400,000 additional estates will pay IHT by 2030 purely due to the freeze. A London or South East property purchased for £200,000 in 2009 now worth £600,000+ pushes a modestly wealthy family's estate well above the threshold. Effective IHT receipts are rising — HMRC IHT receipts hit £7.5bn in 2024/25, up from £5.1bn in 2020/21.

Autumn Budget 2024 APR/BPR reform is the biggest agricultural and business IHT change in 30 years — affects farming families severely
From April 2026, Business Property Relief (BPR) and Agricultural Property Relief (APR) are capped at £1m combined at 100% relief. Above £1m, relief reduces to 50% — meaning the taxable value is 50% of excess, taxed at 40% = 20% effective rate above the £1m threshold. Previously, qualifying businesses and farms could pass entirely IHT-free regardless of value. A farm worth £5m now faces: £1m at 0% (relief) + £4m at 50% relief = £2m taxable × 40% = £800,000 IHT. This has triggered significant protest from the farming community and is under legal challenge. The reform significantly affects the approximately 30,000 UK farm businesses expected to change hands through succession by 2035.

The 7-year rule remains one of the UK's most valuable IHT planning tools — but the clock must start early
Gifts made to individuals become Potentially Exempt Transfers (PETs) under IHTA 1984 §3A — they fall outside the estate entirely if the donor survives 7 years after the gift. If death occurs within 3 years, no taper relief; years 3-7, taper reduces IHT from 40% toward zero. This means significant wealth can be transferred tax-free: a parent giving children £500,000 at age 70 and surviving to age 77+ pays zero IHT on that transfer. Combined with the annual £3,000 exemption, small gift exemption (£250 per recipient), and normal expenditure from income exemption (potentially unlimited for regular gifts from income), UK IHT is highly avoidable with early planning. The main risk: dying within 7 years of the gift.

UK Inheritance Tax — Key Thresholds and Rates 2026
HMRC IHT — IHTA 1984 as amended by Finance Acts
| Threshold / Relief | Amount (£) | Conditions | Notes |
|---|---|---|---|
| Nil Rate Band (NRB) | £325,000 | Per individual estate | Frozen until April 2030 — then review |
| Residence Nil Rate Band (RNRB) | £175,000 | Main home passing to direct descendants | Tapered away above £2m net estate — £1 per £2 over threshold |
| Transferred NRB (spouse) | Up to £325,000 extra | Unused NRB from predeceased spouse/CP | Both NRBs combined: up to £650,000 |
| Transferred RNRB (spouse) | Up to £175,000 extra | Unused RNRB from predeceased spouse/CP | Both RNRBs combined: up to £350,000 |
| Maximum threshold (couple with home) | £1,000,000 | NRB + RNRB × 2, home to children | Standard planning target for most families |
| IHT Rate — Standard | 40% | On estate above threshold | Flat rate |
| IHT Rate — Charitable | 36% | If 10%+ of net estate to charity | Reduced rate incentivises charitable giving |
| Business Property Relief (BPR) | 100% up to £1m / 50% above (from Apr 2026) | Qualifying business assets | Major reform from April 2026 Autumn Budget |
| Agricultural Property Relief (APR) | 100% up to £1m / 50% above (from Apr 2026) | Agricultural property | BPR + APR combined cap £1m — reformed |
| Annual Exemption | £3,000/year | Per donor — carry forward 1 year | Use it or lose it — cumulative max £6,000 in year 2 |
| Small Gift Exemption | £250 per recipient | Per tax year — any number of recipients | Cannot combine with annual exemption for same person |
| Wedding/Civil Partnership Gifts | £5,000 (parent) / £2,500 (grandparent) / £1,000 (other) | Must be given in contemplation of marriage | Occasions-based — per event |
| Normal Expenditure from Income | Unlimited | Regular gifts from surplus income — same pattern each year | Powerful — must evidence pattern and surplus |
ⓘ The RNRB is tapered by £1 for every £2 the net estate exceeds £2,000,000 — so an estate of £2,350,000 loses the entire £175,000 RNRB. This taper disproportionately affects single people and those with larger estates who cannot benefit from two transferable NRBs. The downsizing addition allows the RNRB to be claimed even if the home was sold or downsized after July 2015.
UK IHT — 7-Year Rule Taper Relief Schedule
IHTA 1984 § 7 — Taper Relief
| Years Between Gift and Death | IHT on Gift (% of 40%) | Effective IHT Rate on Gift | Notes |
|---|---|---|---|
| 0-3 years | 100% of 40% | 40% | Full IHT if donor dies within 3 years |
| 3-4 years | 80% of 40% | 32% | Taper relief starts at year 3 |
| 4-5 years | 60% of 40% | 24% | Significant reduction |
| 5-6 years | 40% of 40% | 16% | |
| 6-7 years | 20% of 40% | 8% | |
| 7+ years | 0% — fully exempt | 0% | Gift completely outside estate |
ⓘ Taper relief only applies when the PET value (the gift) exceeds the available nil rate band. If the gift is within the NRB, there is no IHT to taper. The 7-year clock restarts with each gift — so gifts must be tracked. IHT on PETs is paid by the recipient (done), not the estate. Note: the Autumn Budget 2024 did NOT reform the 7-year rule — it remains unchanged.

| Large estate — couple | £3,000,000 | £650,000 (NRBs only — RNRB tapered out) | £2,350,000 | £940,000 | 31.3% effective — RNRB gone above £2m taper |
| Business owner (pre-Apr 2026) | £5,000,000 (farm) | £325,000 NRB + 100% APR on all | £0 | £0 | Old rules — complete exemption |
| Business owner (from Apr 2026) | £5,000,000 (farm) | £325,000 + £1m APR at 100% + £3.675m at 50% APR | £1,837,500 taxable | £735,000 | New rules — significant IHT |
| Charitable bequest 10%+ | £1,000,000 | £325,000 NRB; 36% rate | £675,000 | £243,000 | 36% vs 40% saves £27,000 — worthwhile |

UK Inheritance Tax Data
UK IHT governed by Inheritance Tax Act 1984 (IHTA 1984) as extensively amended by subsequent Finance Acts. Key reforms: Residence Nil Rate Band introduced 2017/18 (Finance (No.2) Act 2015); RNRB taper for estates above £2m; Autumn Budget October 2024 — APR/BPR £1m cap (from April 2026), pensions into estate (from April 2027), NRB freeze to 2030. HMRC administers IHT — probate cannot be granted until IHT is paid or deferred. IHT threshold freeze has been the most significant effective tax increase — real threshold has fallen from £325,000 (2009) equivalent to approximately £180,000 in 2009 prices by 2026.
Formula
IHT = max(0, (Estate − NRB − RNRB − Exemptions) × 0.40) | RNRB_available = max(0, £175,000 − (Estate − £2,000,000) / 2) | PET_charge = Gift_value × Taper_factor × 0.40

❓ Frequently Asked Questions
The UK nil rate band (NRB) is £325,000 per person — frozen at this level since April 2009 and extended until April 2030. On top of this, the residence nil rate band (RNRB) adds £175,000 when a main home passes to direct descendants (children, grandchildren). A married couple or civil partnership can combine both spouses' allowances: up to £650,000 NRBs plus up to £350,000 RNRBs = £1,000,000 combined threshold if the family home passes to children. Above the threshold, IHT is charged at 40%.
Gifts to individuals (called Potentially Exempt Transfers or PETs) become completely exempt from IHT if the donor survives 7 years after making them. If the donor dies within 7 years, taper relief reduces the IHT charge: 0-3 years: 40% (no relief); 3-4 years: 32%; 4-5 years: 24%; 5-6 years: 16%; 6-7 years: 8%. The 7-year clock starts from the date of the gift. There is no limit on the size of PETs — a parent can give £1m to a child and if they survive 7 years, no IHT applies. This is the most widely used UK IHT planning strategy.
The Autumn Budget 2024 (October 2024) introduced major reforms effective April 2026: (1) Business Property Relief (BPR) and Agricultural Property Relief (APR) are capped at £1,000,000 combined at 100% relief — above £1m, relief reduces to 50%. Previously unlimited qualifying businesses and farms could pass completely IHT-free. (2) From April 2027, unused pension pots are brought into the IHT estate — previously pensions were completely outside the estate. The NRB remains frozen at £325,000 until April 2030. These are the most significant IHT reforms since the RNRB was introduced in 2017.
The RNRB (£175,000 in 2026) is an additional IHT threshold available when a qualifying residential property is left to direct descendants (children, stepchildren, adopted children, grandchildren). The property must have been the deceased's main residence at some point. The RNRB is tapered away for larger estates: £1 reduction per £2 of estate value above £2,000,000 — so an estate worth £2,350,000 loses the entire £175,000 RNRB. A downsizing addition allows the RNRB equivalent credit even if the property was sold and not replaced, provided proceeds remain in the estate.
The normal expenditure out of income exemption (IHTA 1984 §21) allows unlimited regular gifts from surplus income to be immediately exempt from IHT — no 7-year wait required. Conditions: (1) the gifts must be made from income, not capital; (2) they must follow a regular pattern (monthly, annual); (3) the donor's standard of living must not be affected. For high earners giving regularly to children (e.g., paying grandchildren's school fees, regular monthly transfers), this exemption is extremely powerful and unlimited. Evidence is critical — HMRC requires a clear pattern and contemporaneous records showing income exceeded expenditure each year after gifts.
