IHT Taper Relief on Gifts UK 2026: How It Works, When It Applies, What It Actually Saves, and When It Saves You Nothing

TRUTH: WRONG — taper reduces the RATE of IHT on the gift, not the amount of the gift that is chargeable. A £300k gift made 5yr before death is still a £300k chargeable transfer — taxed at 24% (not 24% of £300k... but £300k at 24% = £72k). The gift is always valued at the date it was made (s160 IHTA — open market value at transfer date).

Myth: £500k gift at 5yr = £300k chargeable (60% taper of value). WRONG. Truth: £500k gift at 5yr = £500k chargeable × 24% rate = £120k IHT (assuming NRB consumed).

TRUTH: WRONG — taper relief only saves IHT if IHT is actually DUE on the gift. If the gift falls entirely within the remaining NRB (£325k), no IHT is owed and taper is completely irrelevant. Taper only saves money when the NRB is consumed by the gift or by earlier gifts.

£200k gift; no prior gifts; full NRB available: NRB covers £200k → £0 IHT regardless of taper rate. No saving from taper. But: £500k gift with NRB consumed: £500k × (40% − 24%) = £80k saving from being in year 4-5 vs year 0-3.

TRUTH: WRONG — taper begins at 3yr but still leaves substantial IHT. At 3-4yr: 32% rate. On a £500k gift with NRB consumed: still £160k IHT. Taper doesn't make the IHT negligible — it reduces it. Only after 7yr is the gift fully exempt.

At 3yr: £500k × 32% = £160k IHT. At 5yr: £500k × 16% = £80k IHT. At 6yr: £500k × 8% = £40k IHT. At 7yr: £0 IHT. Taper provides significant but not complete relief in years 3-7.

TRUTH: WRONG — the PRIMARY liability for IHT on a failed PET rests with the DONEE (recipient — s204 IHTA 1984). HMRC can pursue the donee directly. The executor is only SECONDARILY liable. The donee is liable up to the value of the gift they received.

Your parent gives you £500k. They die 4yr later. You (the donee) owe up to £160k IHT (32% rate, NRB consumed). HMRC can pursue you directly — even if the executor fails to declare the gift.

TRUTH: MOSTLY WRONG — the PET is valued at the date of the gift (s160 IHTA). If the gift was £500k and has since fallen to £300k: the chargeable amount is still £500k. Exception: s131 IHTA (Relief for changes in value) — only applies to land/buildings sold within 4yr of death (not shares or cash).

Gift of listed shares: £500k at date of gift. Shares now worth £200k. Chargeable PET: £500k (not £200k). IHT is on the original gift value. No fall-in-value relief for non-land assets. This is why large share gifts can be particularly punishing if the shares collapse after the gift.

The mechanics of taper relief — what actually changes as the years pass

Taper relief under s7(4) IHTA 1984 operates as a step function, not a continuous curve. The relief jumps at each year boundary: the moment a gift passes 3yr, 4yr, 5yr, 6yr, or 7yr before the date of death, the applicable rate drops. Between these boundaries: the rate is flat. A gift made 3yr 1 day before death is taxed at 32%; a gift made 2yr 364 days before death is taxed at 40% — a difference of 8pp for just one day. This means the precise date of the gift matters significantly near the year boundaries. For a £500k gift with the NRB consumed: crossing from the 0-3yr band to the 3-4yr band at exactly 3yr saves £40,000. Crossing from the 6-7yr band to full exemption at exactly 7yr saves the remaining 8% = £40,000 (£500k × 8%). The 7yr clock starts on the date the gift is made — the date of the legal transfer, not the date of any deed of trust or announcement. For cash: the date the funds clear into the recipient's account. For property: the date of completion. For shares: the date of the stock transfer form registration.

When taper relief is worth nothing — the NRB interaction

This is the most important point about taper relief that is widely misunderstood: taper relief only saves IHT when IHT is actually due. IHT is only due on a failed PET when the PET exceeds the available NRB (after accounting for other gifts in the 7yr cumulation window). The NRB in 2026/27 is £325,000. If the failed PET is £200,000 and no prior gifts have consumed the NRB: the £200,000 PET is entirely covered by the NRB. IHT = £0. Taper relief = irrelevant. All 7 taper bands give the same result: £0. For a married couple, the estate at death also has the RNRB (£175k) and potentially tNRB — but these apply to the estate itself and do not increase the NRB against cumulative gifts during the 7yr window. Taper becomes meaningfully valuable when: (a) the single gift exceeds the NRB (£325k); OR (b) earlier gifts in the 7yr window have consumed part of the NRB, and the additional PET takes the total above £325k. Example: prior PETs in the 7yr window = £200k. New PET (4yr before death) = £300k. Combined = £500k. NRB: £325k. Excess on which IHT is due: £500k − £325k = £175k. IHT at 4-5yr rate (24%): £175k × 24% = £42,000 IHT. Without taper (0-3yr rate): £175k × 40% = £70,000. Taper saving: £28,000. If the prior PETs were nil: taper saving on the same £300k PET at 4-5yr vs 0-3yr = 0 (NRB covers the entire £300k).

How life assurance covers the taper risk for donors making large gifts

A donor who makes a large PET (above the NRB) takes on IHT risk for the following 7yr. The risk is: if the donor dies within 7yr, the donee owes IHT on the gift (s204 IHTA). The standard planning response is a 7yr decreasing term assurance policy, written in a discretionary trust. The policy: (a) has a term of 7 years from the date of the gift; (b) the sum assured decreases over time to match the decreasing IHT liability as taper relief reduces the rate. For a £500k gift with NRB consumed: year 0-3: IHT £200k; year 3-4: IHT £160k; year 4-5: IHT £120k; year 5-6: IHT £80k; year 6-7: IHT £40k; after 7yr: £0. A decreasing term policy mirrors this liability profile — it pays £200k if the donor dies in year 0-3, stepping down to £40k in year 6-7. The policy is written in trust (typically a discretionary trust) so the proceeds pass outside the donor's estate — no IHT on the policy payout itself. If the donor survives 7yr: the policy lapses with no payout. Cost: typically £300-£800/yr depending on the donor's age and health for a £500k initial sum assured over 7yr. The policy cost from surplus income may qualify as normal expenditure from income (s21 IHTA — immediately exempt). The donee can also fund their own policy to cover their personal IHT liability.

The rolling NRB benefit of long-term gifting strategies

One of the most powerful — and least discussed — benefits of systematic lifetime gifting is how gifts falling outside the 7yr window progressively free up the NRB for subsequent gifts. The NRB (£325k) applies to the cumulative chargeable transfers (including failed PETs) in the 7yr before death. Gifts made more than 7yr before death drop OUT of the cumulation window and no longer consume the NRB. Example of a rolling gift programme: Mr Smith makes a £300k PET in year 1. At year 8 (7yr have passed): that £300k drops outside the 7yr window — the full NRB (£325k) is available again for new gifts. Mr Smith makes another £325k PET in year 8. At year 15: the year-8 gift drops out. The NRB refreshes again. This rolling programme, over 20+ years, can transfer £325k tax-free every 7yr — potentially £900k+ outside the estate over 21yr — with zero IHT (as long as the donor survives 7yr after each gift). Combined with the annual exemption (s19 IHTA — £3k/yr immediately exempt), small gifts exemption (s20 — £250/person), and normal expenditure from income (s21 — unlimited), a sustained gifting programme is one of the most effective IHT reduction strategies available to individuals with large estates.

How does IHT taper relief on gifts work?

IHT taper relief (s7(4) IHTA 1984) reduces the RATE of IHT on a failed Potentially Exempt Transfer (PET — gift that becomes chargeable because the donor died within 7 years). Rates: 0-3yr before death: 40%; 3-4yr: 32%; 4-5yr: 24%; 5-6yr: 16%; 6-7yr: 8%; 7+yr: 0% (fully exempt). CRITICAL: taper reduces the RATE not the gift value. The PET is always chargeable at its full amount (s160 IHTA — open market value at date of transfer). Taper only saves IHT if IHT is actually due — i.e., if the failed PET exceeds the remaining NRB (£325k). If the gift is within the NRB: no IHT regardless of taper. Example: £500k gift, NRB consumed by prior gifts, 4-5yr before death: £500k × 24% = £120,000 IHT. NOT £500k × 60% (taper) = £300k chargeable — a common mistake.

Does IHT taper relief apply to all gifts?

Taper relief only makes a financial difference when IHT is actually owed on the gift — i.e., when the failed PET exceeds the available NRB (£325k). If the gift is covered by the NRB: no IHT is owed regardless of when the gift was made, and taper relief has no practical effect. Taper matters when: (1) the gift alone exceeds the NRB; or (2) earlier gifts in the 7yr cumulation window have consumed part of the NRB, and the additional PET takes the total above £325k. Example where taper saves nothing: £200k gift; no prior gifts; NRB = £325k; £200k < £325k; IHT = £0 in all taper bands. Example where taper saves £80k: £500k gift; NRB already consumed; year 0-3: £500k × 40% = £200k; year 4-5: £500k × 24% = £120k; saving = £80k.

Who pays the IHT on a failed gift — the estate or the recipient?

The PRIMARY liability for IHT on a failed PET (gift where donor dies within 7yr) rests with the DONEE — the person who received the gift (s204 IHTA 1984). HMRC can pursue the donee directly. The executor of the deceased's estate is SECONDARILY liable. In practice: the executor calculates all failed PETs on IHT403 and the estate typically meets the liability — but if the estate cannot pay, HMRC pursues the donee personally, up to the value of the gift received. This surprises many gift recipients: they may have spent or reinvested the gift and still face a substantial IHT bill years later. Life assurance (written in trust) taken out by the donor at the time of the gift can provide the funds to meet this liability.

What is the 7-year rule for IHT taper relief?

The '7-year rule' is the period a donor must survive after making a Potentially Exempt Transfer (PET) for the gift to become fully exempt from IHT. If the donor survives 7yr: the gift is entirely outside the IHT estate and does not consume the NRB. If the donor dies within 7yr: the PET 'fails' and becomes chargeable at the taper rate for the year in which it falls. Taper relief (s7(4) IHTA): 0-3yr: 40%; 3-4yr: 32%; 4-5yr: 24%; 5-6yr: 16%; 6-7yr: 8%. After 7yr: 0% (fully exempt). The 7yr clock starts on the date of the gift — the legal transfer date. The precise date matters near year boundaries (crossing from year 2 to year 3 saves 8pp of tax on the gift).

Can you use life insurance to cover the IHT risk on a large gift?

Yes — a 7-year decreasing term life assurance policy (written in a discretionary trust) is the standard planning tool to cover the IHT risk on a large PET. The policy: (1) runs for 7 years from the date of the gift; (2) has a decreasing sum assured matching the reducing IHT liability as taper relief reduces the rate over years 3-7; (3) is written in trust so the proceeds pass outside the donor's estate (no IHT on the payout). If the donor survives 7yr: the policy lapses — no payout needed (the gift is fully exempt). If the donor dies within 7yr: the policy pays out to meet the donee's IHT liability. Premiums paid from surplus income may qualify for normal expenditure from income exemption (s21 IHTA — immediately exempt from IHT, no 7yr clock). Cost: varies by age, health, and sum assured. Specialist financial advice required.
