Most people planning their estate have heard of the “7-year rule”: give money away, survive seven years, and the gift falls outside your estate for inheritance tax (IHT). It’s one of the best-known ideas in estate planning — and one of the most misunderstood.
Far fewer have heard of its longer, stranger cousin: the 14-year rule. Because it works quietly in the background, it can produce an IHT bill that families simply don’t see coming.
Here’s what it actually means — in plain English, with worked examples.
First, a quick recap of the 7-year rule
When you make an outright gift to another person — cash to a child or grandchild, say — it’s known as a potentially exempt transfer, or PET. The word “potential” is doing the heavy lifting:
- Survive seven years from the date of the gift, and it leaves your estate entirely. No IHT.
- Die within seven years, and the gift “fails” — it’s brought back into the calculation and may be taxed.
Where tax is due on a gift made between three and seven years before death, taper relief can reduce it on a sliding scale. Importantly, taper relief reduces the tax, not the value of the gift — a distinction that trips up a lot of people.
So far, so familiar. But this is only half the story, because not every gift is a PET.
The piece most people miss: gifts into trust
When you transfer assets into most types of trust, you are not making a PET. You are making a chargeable lifetime transfer (CLT). CLTs are treated differently — and, crucially, they have a long memory.
Every time you make a chargeable transfer, HMRC looks back seven years from the date of that transfer to see what you have already given away chargeably. Those earlier gifts use up your nil-rate band (currently £325,000) first, before the current gift gets any.
Now watch what happens when the two interact.
Where “14 years” comes from
Suppose you put money into trust (a CLT), and a few years later make an outright gift to a child (a PET). Then you die within seven years of the PET.
To calculate the tax on the failed PET, HMRC looks back seven years from the date of the PET — not from the date of your death. If your earlier CLT falls inside that window, it is pulled into the running total and eats into the nil-rate band available to the PET.
The CLT could have been made up to seven years before the PET, and the PET up to seven years before death:
7 years + 7 years = up to 14 years before death during which an old gift can still influence the tax.
The CLT itself is not taxed again — it sits outside the seven years before death. But it can quietly increase the tax on the later gift. That is the sting in the tail.
A worked example
Meet a client who made two gifts in their lifetime:
| Date | Gift | Type | Amount |
| January 2015 | Into a discretionary trust | CLT | £200,000 |
| January 2020 | To their daughter | PET | £300,000 |
| June 2026 | Client dies | — | — |
At the date of death (June 2026):
- The 2015 trust gift was made over 11 years ago — well outside seven years. On its own, it attracts no IHT on death.
- The 2020 gift to the daughter was made about six and a half years ago — inside seven years. It is a failed PET and becomes chargeable.
To tax the failed 2020 gift, we look back seven years from January 2020 — back to January 2013. The 2015 trust gift sits squarely inside that window, so it uses up part of the nil-rate band first:
| Step | Amount |
| Nil-rate band | £325,000 |
| Less: 2015 trust gift (within 7 years of the PET) | (£200,000) |
| Nil-rate band available to the 2020 gift | £125,000 |
| 2020 gift | £300,000 |
| Taxable amount (£300,000 − £125,000) | £175,000 |
| IHT at 40% | £70,000 |
| Less: taper relief (6–7 years before death, 80% reduction) | (£56,000) |
| IHT payable | £14,000 |
Now the “what if”
Here is the part that surprises people. If the 2015 trust gift had never been made, the full £325,000 nil-rate band would have been available to the 2020 gift:
- 2020 gift of £300,000, fully covered by the £325,000 band → £0 tax.
So a trust gift made more than eleven years before death — a gift that is itself completely outside the seven-year net — created a £14,000 tax charge on a later gift. That is the 14-year rule at work.
One further point families rarely anticipate: the person primarily liable for the tax on a failed PET is usually the recipient — here, the daughter — not the estate. A gift that felt final can come back to the beneficiary years later.
A second scenario: what if the gift into trust comes second?
It’s tempting to assume the order of your gifts doesn’t matter. It does — and comparing the two orderings is the clearest way to see what the 14-year rule really is.
This time, the outright gift (the PET) comes first, and the trust gift (the CLT) comes second:
| Date | Gift | Type | Amount |
| March 2021 | To their son | PET | £200,000 |
| March 2023 | Into a discretionary trust | CLT | £300,000 |
| June 2026 | Client dies | — | — |
Two things to notice at the outset:
- When the trust gift was made in 2023, the 2021 gift to the son was still a PET — potentially exempt — so it was ignored when the trust gift was measured against the nil-rate band. The £300,000 trust gift sat within the £325,000 band, so no lifetime tax was due at that point.
- On death in 2026, both gifts fall within seven years, so both are back in play — and they are dealt with in date order.
The earlier gift goes first and takes the nil-rate band:
- The 2021 gift to the son (£200,000) is within the £325,000 band, so there is no tax on it — but it uses up £200,000 of the band.
- The 2023 trust gift (£300,000) is then recalculated on death with only £125,000 of band left:
| Step | Amount |
| Nil-rate band | £325,000 |
| Less: 2021 gift to son (now a failed PET, earlier in time) | (£200,000) |
| Nil-rate band available to the trust gift | £125,000 |
| Trust gift | £300,000 |
| Taxable amount (£300,000 − £125,000) | £175,000 |
| IHT at 40% | £70,000 |
| Less: taper relief (3–4 years before death, 20% reduction) | (£14,000) |
| IHT payable | £56,000 |
Had the son’s gift never been made, the trust gift would have had the full £325,000 band and faced no tax at all. So, once again, an earlier gift has quietly created a charge on a later one — this time £56,000, payable by the trustees.
A third scenario: one trust gift after another (CLT after CLT)
The clearest illustration of all is two trust gifts in a row. Because a chargeable lifetime transfer is taxable the moment it is made, there is no seven-year “survival” period to clear first — the cumulation simply runs from one gift to the next, and straight through to death.
| Date | Gift | Type | Amount |
| January 2018 | Into a discretionary trust | CLT | £200,000 |
| March 2023 | Into a second discretionary trust | CLT | £300,000 |
| June 2026 | Client dies | — | — |
This ordering has one feature the others don’t: the second trust gift can trigger an immediate tax charge during your lifetime.
During lifetime (March 2023). The 2018 trust gift had already used part of the nil-rate band, and — being a chargeable transfer — it counts straight away:
| Step | Amount |
| Nil-rate band | £325,000 |
| Less: 2018 trust gift (within 7 years) | (£200,000) |
| Nil-rate band available to the 2023 trust gift | £125,000 |
| 2023 trust gift | £300,000 |
| Taxable amount (£300,000 − £125,000) | £175,000 |
| Lifetime tax at 20% | £35,000 |
So £35,000 is payable straight away (this assumes the trustees meet the tax from the trust fund; if the settlor pays it personally, the effective rate is 25% through “grossing up”).
On death (June 2026). The 2023 trust gift is recalculated at the death rate, with credit for the £35,000 already paid:
| Step | Amount |
| Taxable amount (as above) | £175,000 |
| IHT at 40% | £70,000 |
| Less: taper relief (3–4 years before death, 20% reduction) | (£14,000) |
| Tax at death | £56,000 |
| Less: lifetime tax already paid | (£35,000) |
| Further IHT payable on death | £21,000 |
And the 2018 trust gift itself? It was made more than seven years before death, so it bears no tax of its own on death. Yet it still reduced the nil-rate band available to the 2023 gift on that death recalculation — because it fell within the seven years before the 2023 gift. That is the 14-year rule in its purest form: here the first gift sits about eight years before death, and could sit as far back as fourteen.
Had the 2018 gift never been made, the 2023 gift of £300,000 would have fallen within the £325,000 band — no lifetime charge and no tax on death. Instead, the earlier gift produced £56,000 of tax in total: £35,000 during life and a further £21,000 on death.
(Trusts also carry their own ten-yearly and exit charges under the relevant property regime — a separate matter from the position on the settlor’s death, and beyond the scope of this note.)
Why the order matters — and why it’s really a “14-year” rule
Line the three scenarios up and a pattern emerges. In the first (trust gift, then outright gift) and the third (two trust gifts), an earlier gift reached across seven, eight, even more years to increase the tax on a later one — right up to fourteen years before death. In the second (outright gift, then trust gift), the earlier gift mattered only because everything happened to fall within seven years of death.
The difference comes down to one thing: when a gift becomes chargeable.
An outright gift — a PET — is only ever chargeable if you die within seven years of it. Survive seven years and it disappears completely; it can never affect anything again. Its reach is capped at seven years.
A trust gift — a CLT — is chargeable from the day it is made. That is what lets it reach across a later gift (up to seven years) and then on to death (another seven) — the full fourteen. Two trust gifts in a row show this most starkly, and add a sting the others lack: an immediate charge in your lifetime.
So the genuinely long shadow is always cast by a trust gift. Put simply, the “14-year rule” is really a chargeable-transfer rule: it is the presence and timing of trust gifts — not outright gifts — that can stretch the tax tail all the way to fourteen years.
A fourth scenario: how a clean seven-year gap resets the band
Every scenario so far has shown an earlier gift increasing the tax on a later one. It is worth seeing the reverse — because the same seven-year mechanism that creates the 14-year reach also works in the client’s favour when gifts are spaced properly.
| Date | Gift | Type | Amount |
| October 2014 | Into a discretionary trust | CLT | £325,000 |
| February 2023 | Into a second discretionary trust | CLT | £325,000 |
| June 2026 | Client dies | — | — |
Here the two trust gifts are more than seven years apart, and each is a full nil-rate band in size.
The first trust gift (2014). By the time the second gift is made in 2023, more than seven years have passed — and HMRC only ever looks back seven years from each transfer. So the 2014 gift drops out of the cumulation entirely. It is also well outside seven years of death. The result: it bears no tax and, crucially, it does not reduce the band available to anything that follows.
The second trust gift (2023). Because the 2014 gift has dropped away, the 2023 gift starts with a fresh, full £325,000 nil-rate band. At £325,000 it sits exactly within that band, so there is no lifetime charge when it is made.
On death (2026). The 2023 gift is within seven years of death, so it is brought back and recalculated — but it is still fully covered by the £325,000 band, so there is no tax on it. And this is the part clients often expect to go differently: taper relief does not come into it. Taper reduces tax, and only on the slice of a gift that exceeds the available band. A gift sitting within the band produces no tax in the first place, so there is nothing for taper to reduce.
So where is the cost? Not on the trust gifts — it falls on the rest of the estate. Because the 2023 gift was made within seven years of death, it still absorbs the whole nil-rate band, leaving nothing for the free estate to set against IHT. (The residence nil-rate band is a separate allowance and is unaffected.)
Had the settlor instead survived the 2023 gift by seven years, that gift would have dropped out of cumulation too — and the full band would have refreshed once more, this time for the estate. That is the whole game: each clear seven-year gap resets the clock.
One caution shows how fine the margins are. If the 2023 gift had been made even a day inside seven years of the 2014 gift, the earlier £325,000 would have cumulated, the later gift would have had no band at all, the full £325,000 would have been chargeable, and a lifetime entry charge of £65,000 (20%) would have fallen due immediately — with taper then genuinely in point on the death recalculation. The seven-year spacing, not taper relief, is doing all the work.
Why this matters
The 14-year rule is not a reason to avoid trusts — trusts remain one of the most effective tools in succession planning. But it does mean three things are worth real attention:
- Order and timing. The sequence in which you make gifts, and how they cluster, can change the tax outcome significantly.
- Trusts cast a long shadow. A chargeable transfer can influence the tax on gifts made up to seven years later — and therefore up to fourteen years before death. It can also trigger an immediate charge in your lifetime if it exceeds the nil-rate band available when it is made.
- Record-keeping is everything. Executors need a clear history of lifetime gifts. A forgotten transfer from a decade ago can quietly reshape the numbers.
- Spacing resets the clock. A clear seven years between chargeable gifts lets the nil-rate band refresh — the very rule that penalises clustered gifts rewards well-spaced ones.
Good planning takes all of this into account before gifts are made — not after.
This article is general information and does not constitute personal advice. Inheritance tax outcomes depend on individual circumstances, and the rules can change. Figures assume a nil-rate band of £325,000 throughout and ignore annual exemptions for clarity; the residence nil-rate band is not considered. Lifetime (“entry”) charges are shown only where a trust gift exceeds the nil-rate band available when it is made, and trustees are assumed to bear any such tax (grossing up at an effective 25% would apply if the settlor paid it personally). Trusts’ own ten-yearly and exit charges are not addressed. Please take advice tailored to your situation before acting.
