Inheritance Tax for Estates Over £2 Million
If your estate is worth more than £2 million, the rules change significantly. The residence nil-rate band starts to disappear, the new APR/BPR cap from April 2026 limits your reliefs, and from April 2027 your pension could push you even further over the threshold. Here is exactly what you face and what you can do about it.

High-Value Estate Thresholds
The RNRB Taper: How It Works Above £2 Million
The residence nil-rate band adds up to £175,000 to your tax-free allowance when you leave your home to direct descendants. But for estates above £2 million, this allowance is gradually withdrawn.
The taper works simply: for every £2 your estate exceeds £2 million, you lose £1 of RNRB. This means:
| Estate value | RNRB lost | RNRB remaining | Extra IHT vs under £2M |
|---|---|---|---|
| £2,000,000 | £0 | £175,000 | £0 |
| £2,100,000 | £50,000 | £125,000 | £20,000 |
| £2,200,000 | £100,000 | £75,000 | £40,000 |
| £2,350,000 | £175,000 | £0 | £70,000 |
| £2,500,000 | £175,000 | £0 | £70,000 |
RNRB taper impact for a single person (own RNRB only)
The effective marginal tax rate in the taper zone is 60%, not 40%. This is because every £2 of additional estate value costs you £1 of RNRB (which would have saved 40p) plus 40% tax on the £2 itself. In practice, an estate worth £2.1 million pays significantly more tax per pound than one worth £2.5 million.
The 60% effective rate in the taper zone makes this one of the most punishing areas of the UK tax system. If your estate is between £2 million and £2.35 million, even small reductions in estate value can produce outsized tax savings.
What This Means in Practice
Three estates, each belonging to a single person leaving everything to their children. Each has a home qualifying for RNRB.
| £2.1M estate | £2.5M estate | £3M estate | |
|---|---|---|---|
| NRB | £325,000 | £325,000 | £325,000 |
| RNRB (after taper) | £125,000 | £0 | £0 |
| Total allowances | £450,000 | £325,000 | £325,000 |
| Taxable amount | £1,650,000 | £2,175,000 | £2,675,000 |
| IHT at 40% | £660,000 | £870,000 | £1,070,000 |
| Effective rate | 31.4% | 34.8% | 35.7% |
Notice how the £2.1 million estate has a lower effective rate because it retains some RNRB. The £2.5 million and £3 million estates have lost the RNRB entirely.
The New APR/BPR Picture from April 2026
For estates that include agricultural or business assets, the April 2026 APR/BPR reform introduces a £2.5 million per person cap on these reliefs. Above this cap, only 50% relief applies (effectively a 20% IHT rate on the excess).
For high-value estates, this creates a double impact:
- The RNRB is lost to the taper (estate over £2 million)
- APR/BPR relief is capped (qualifying assets over £2.5 million)
- More of the estate is taxable on both fronts
Edward owns a farm valued at £2.8 million and has other assets worth £700,000. His total estate is £3.5 million. He is single and leaves everything to his daughter.
| Component | Before April 2026 | After April 2026 |
|---|---|---|
| Farm value | £2,800,000 | £2,800,000 |
| APR relief | £2,800,000 (100%) | £2,500,000 at 100% + £150,000 at 50% |
| Taxable farm value | £0 | £150,000 |
| Other assets | £700,000 | £700,000 |
| Total taxable | £700,000 | £850,000 |
| Less: NRB | −£325,000 | −£325,000 |
| Less: RNRB (tapered to £0) | £0 | £0 |
| Taxable estate | £375,000 | £525,000 |
| IHT at 40% | £150,000 | £210,000 |
The combination of the RNRB taper and the APR/BPR cap costs Edward's estate an additional £60,000 from April 2026.
Using Trusts to Reduce the Taxable Estate Below £2M
Some families consider using trusts to bring the estate value below the £2 million RNRB taper threshold. Common approaches include:
- Discretionary trusts: Assets transferred into a discretionary trust during your lifetime leave your estate after seven years (subject to the seven-year rule). However, there may be entry charges if you transfer more than £325,000 into trust.
- Loan trusts: You lend money to a trust (interest-free). The loan remains in your estate, but any growth on the invested amount sits outside it.
- Discounted gift trusts: You give up capital in exchange for a fixed income stream. The “discount” (the capital minus the value of your retained income) leaves your estate immediately.
Trust planning for IHT is complex and should only be done with qualified professional advice. Trusts have their own tax charges (entry, periodic, and exit charges), and HMRC may challenge arrangements that appear to be primarily motivated by tax avoidance.
Pension IHT from 2027: How This Changes the Picture
From April 2027, unspent defined contribution pension pots will be included in your taxable estate. For larger estates, this has two compounding effects:
- More estate value: The pension adds directly to the estate, increasing the IHT bill
- RNRB taper: If the pension pushes the estate above £2 million (or further above), the RNRB taper reduces or eliminates the residence nil-rate band
Read our pension and IHT 2027 guide for detailed worked examples showing how the pension inclusion interacts with the RNRB taper.
Gifts and the 7-Year Rule for Significant Estates
For estates well above the IHT thresholds, lifetime gifting is one of the most effective planning tools. Gifts become potentially exempt transfers (PETs) and fall completely outside the estate if you survive seven years.
For large estates, even modest annual gifting can make a meaningful difference over time:
| Strategy | Annual amount | Value after 10 years | IHT saved at 40% |
|---|---|---|---|
| Annual exemption (both spouses) | £6,000 | £60,000 | £24,000 |
| Normal expenditure from income | £20,000 | £200,000 | £80,000 |
| Larger PETs (if survive 7 years) | £50,000 | £500,000 | £200,000 |
| Combined strategy | £76,000 | £760,000 | £304,000 |

Case Study: Robert and Patricia
Robert (74) and Patricia (71) are married. Their estate includes a family home worth £1.2 million, investments of £900,000, a small farm (APR qualifying) worth £500,000, and Robert's pension pot of £200,000. They plan to leave everything to their three children.
Scenario A: No planning, death after April 2027
Assume Patricia dies first (everything to Robert under spouse exemption), then Robert dies. Robert's estate includes the pension from April 2027.
| Component | Value |
|---|---|
| Family home | £1,200,000 |
| Investments | £900,000 |
| Small farm (APR qualifying) | £500,000 |
| Pension (included from April 2027) | £200,000 |
| Gross estate | £2,800,000 |
| Less: APR on farm (100% — under £2.5M cap) | −£500,000 |
| Net estate for RNRB taper test | £2,300,000 |
| RNRB (own + Patricia's transferred) | £350,000 → tapered to £200,000 |
| NRB (own + Patricia's transferred) | £650,000 |
| Total allowances | £850,000 |
| Taxable estate | £1,450,000 |
| IHT at 40% | £580,000 |
Scenario B: With planning
Robert and Patricia gift £50,000 per year to their children using annual exemptions and normal expenditure from income. After 5 years, they have reduced the estate by £250,000. Robert also draws down his pension and gifts the surplus income.
| Component | Value |
|---|---|
| Gross estate (after 5 years of gifting) | £2,550,000 |
| Less: pension drawn down and gifted | −£150,000 |
| Adjusted gross estate | £2,400,000 |
| Less: APR on farm | −£500,000 |
| Net estate for RNRB taper test | £1,900,000 |
| RNRB (below £2M — full £350,000 available) | £350,000 |
| NRB (own + Patricia's transferred) | £650,000 |
| Total allowances | £1,000,000 |
| Taxable estate | £900,000 |
| IHT at 40% | £360,000 |
The planning saves £220,000 in IHT. The biggest single saving comes from getting the estate below £2 million for the RNRB taper test, which restores the full £350,000 RNRB.
Frequently Asked Questions
What happens to the RNRB for estates over £2 million?
The residence nil-rate band tapers by £1 for every £2 the estate exceeds £2 million. For a single person, the RNRB of £175,000 is completely lost at £2.35 million. For a surviving spouse claiming transferred RNRB (up to £350,000), it is fully lost at £2.7 million.
How much inheritance tax does a £3 million estate pay?
A £3 million estate with no RNRB (lost to taper) and a single NRB of £325,000 would pay IHT of £1,070,000 (£2,675,000 × 40%). A surviving spouse with transferred NRB could reduce this to £950,000. The exact figure depends on whether reliefs like BPR, APR, or charity exemptions apply.
How can I reduce my estate below £2 million to keep the RNRB?
Strategies include lifetime gifting (subject to the 7-year rule), making charitable donations, using trusts, spending down assets, and ensuring debts and liabilities are accounted for. However, artificial arrangements to reduce the estate value may be challenged by HMRC under anti-avoidance rules.
Does the APR/BPR cap from April 2026 affect estates over £2 million?
Yes. From April 2026, APR and BPR qualifying assets above £2.5 million per person receive only 50% relief instead of 100%. For high-value estates that include business or agricultural assets, this means less relief is available and more of the estate is taxable.
Will pensions push my estate over £2 million from April 2027?
Potentially yes. From April 2027, unspent defined contribution pension pots are included in the taxable estate. If your estate is currently below £2 million, adding your pension value could push it above the threshold and trigger the RNRB taper — losing you up to £175,000 (or £350,000) of additional allowance.
