The Deed of Variation 2-Year Rule: What Happens If You Miss the Deadline
A deed of variation must be made within two years of the date of death — not the date of probate. Do that, and the law treats the redirected gift as though the deceased had written it into their own will, which can rewrite the inheritance tax (IHT) and capital gains tax (CGT) outcome. Miss the two-year window and the door to "reading back" closes for good: you can still give the money away, but it becomes your gift, which restarts the seven-year clock and offers no IHT saving on the estate itself.
What the two-year rule actually says
The deed of variation (also called an instrument of variation, or IOV) is created by section 142 of the Inheritance Tax Act 1984. The opening words of the section set the clock running from one fixed point:
"Where within the period of two years after a person's death" a beneficiary varies or disclaims their entitlement, and the conditions are met, "this Act … shall apply as if the variation had been made by the deceased."
— Inheritance Tax Act 1984, s.142(1). A near-identical relief for CGT sits in s.62(6) of the Taxation of Chargeable Gains Act 1992.
Two things in that sentence do the heavy lifting:
- "Within … two years after a person's death." The window is calendar-fixed. It runs from the date of death on the death certificate — never from the funeral, the grant of probate, or the date the estate is distributed.
- "As if the variation had been made by the deceased." This is the famous "reading back." Provided you stay inside two years and meet the formalities, HMRC treats the new destination of the gift as if it had been in the will from the start. The original beneficiary is not treated as having made a gift at all.
For the reading-back to bite, GOV.UK and s.142 require all of the following (the points HMRC checks on form IOV2):
- The variation is in writing (a deed is usual but a signed letter can qualify).
- It is signed within two years of the death by everyone who is giving up an entitlement.
- Everyone made worse off by the change agrees — you cannot vary away someone else's share without their consent.
- It contains a statement of intention that s.142(1) (and, if relevant, s.62(6) TCGA for CGT) is to apply. Section 142(2) is explicit: the relief "shall not apply … unless the instrument contains a statement, made by all the relevant persons, to the effect that they intend the subsection to apply."
- It is not made for consideration in money or money's worth — you cannot be paid to vary your share (s.142(3)).

Priya's variation at 18 months — and why it saved IHT.
Margaret died on 1 March 2025, leaving a UK estate of £700,000. Her will left everything to her son, Daniel, who is comfortably off and already has a taxable estate of his own. Daniel would rather his two children (Margaret's grandchildren) receive £200,000 between them, and he wants to do it without making a gift that hangs over his own estate for seven years.
Step 1 — Check the clock. Death was 1 March 2025. The two-year window closes on 1 March 2027. The grant of probate was issued in September 2025, but that date is irrelevant to the deadline.
Step 2 — Execute the deed at 18 months. In September 2026 (18 months after death, comfortably inside the window) Daniel signs a deed of variation redirecting £200,000 of his inheritance to his children. The deed includes the statement of intent that s.142(1) IHTA 1984 is to apply. Daniel is the only person giving anything up, so he is the only "relevant person" who must sign.
Step 3 — The reading-back result. For IHT, the £200,000 is treated as though Margaret had left it to the grandchildren directly. It is not a transfer from Daniel. The figures:
| Item | Without variation | With variation (read back) |
|---|---|---|
| Margaret's estate | £700,000 | £700,000 |
| Who is treated as the donor of the £200,000 | Daniel (a lifetime gift) | Margaret (under her will) |
| Is it a Potentially Exempt Transfer from Daniel? | Yes — 7-year clock starts | No — never enters Daniel's estate |
| Effect if Daniel dies within 7 years | £200,000 could fall back into Daniel's IHT bill | No effect — it was never his to give |
Why this matters: Margaret's estate IHT does not change just by switching who receives the £200,000 within the family — the tax on her estate is calculated the same way. What the variation buys Daniel is certainty: because the £200,000 is read back into Margaret's will, it is never a gift from him, so there is no seven-year survivorship risk attached to his own estate. Had he simply handed the children £200,000 himself, it would be a Potentially Exempt Transfer (PET) that only becomes fully exempt if he survives seven years.
Figures illustrative. The standard nil-rate band is £325,000 and the IHT rate above it is 40% — see the thresholds note below. Always model the specific estate; reliefs such as the residence nil-rate band can change the numbers.
What "reading back" does — and does not — change
It is worth being precise, because the phrase "saves inheritance tax" is often used loosely. A variation does not reduce the IHT on the estate of the person who died simply by moving money between beneficiaries. What reading-back changes is whose estate the gift is treated as coming from. That can create real savings where the original beneficiary would otherwise have made a taxable gift, or where redirecting to a spouse, charity, or grandchildren unlocks a relief (spouse exemption, the charity rate, or the residence nil-rate band passing to direct descendants).
- The two-year deadline runs from the date of death, full stop — not probate, not distribution.
- Inside the window, a valid s.142 variation is read back: the new gift is treated as the deceased's, not the original beneficiary's.
- You must include a statement of intent that s.142(1) applies (and s.62(6) TCGA for CGT) — without it, HMRC will not give the relief.
- Anyone made worse off must agree and sign; you cannot be paid to vary (no consideration).
- Miss two years and the only route left is a plain lifetime gift, which restarts the seven-year PET clock and gives no estate-level reading-back.
What you can still do after the two years are up
Missing the deadline is not the end of the world — but it changes the tax mechanics entirely. After two years you can no longer "read back" anything. The options that remain are ordinary lifetime planning:
1. Make a plain gift (and restart the 7-year clock)
The beneficiary who received the inheritance simply gives some of it away. This is a Potentially Exempt Transfer: it falls out of the giver's estate for IHT only if they survive seven years from the date of the gift. Die within seven years and some or all of it is dragged back into the giver's estate (with taper relief on the tax, not the gift, between years three and seven). The key difference from a variation: the gift is now treated as coming from the living beneficiary, never from the deceased.
2. Use the normal lifetime exemptions
The £3,000 annual exemption, small-gift exemption (£250 per person), gifts out of surplus income, and wedding gifts all still apply to anything given after the window closes. These are immediate exemptions and do not depend on surviving seven years.
3. Consider a deed of family arrangement for non-tax reasons
You can still rearrange who gets what by agreement after two years — for fairness, to settle a dispute, or to fund a trust — but it will be treated for tax as the beneficiaries' own gifts. The reading-back relief is simply unavailable.
| Deed of variation (within 2 years) | Plain gift (after 2 years) | |
|---|---|---|
| Treated as a gift from | The deceased | The living beneficiary |
| 7-year survivorship needed? | No | Yes (PET) |
| Statement of intent required? | Yes (s.142(2)) | No |
| Can unlock spouse / charity / RNRB on the estate? | Yes | No (estate already settled) |
| Deadline | 2 years from date of death | None — but clock resets each gift |
How the deadline interacts with the grant of probate
This trips people up constantly, so to be unambiguous: the two-year clock does not wait for probate. It starts on the date of death and keeps running whether or not the grant has been issued, whether or not the estate has been valued, and whether or not the assets have been distributed.
Two practical consequences:
- A slow grant eats into your window. If probate takes a year (not unusual for complex estates), you have one year left, not two. Where a variation is clearly going to be wanted, draft it in parallel with the probate process rather than after distribution.
- You can vary before probate is granted. You do not have to wait for the grant to sign a valid deed of variation — beneficiaries can agree and execute it at any point inside the two years. In practice you need the estate values to draft it sensibly, but legally the grant is not a precondition.
If the variation increases the IHT due on the estate, you must send a copy of the instrument to HMRC within six months of making the variation. That six-month duty is separate from — and in addition to — the two-year deadline for the variation itself. (Source: GOV.UK.)
Evidence HMRC wants to confirm the date the variation was executed
Because the entire relief turns on the variation being made inside the two years, HMRC's focus is on proving when it was executed. Sloppy paperwork here can lose the relief even when the substance was sound. Build the file as if HMRC will ask — because on a checked estate, it will.
- A clearly dated, signed instrument. Every signatory should date their signature. An undated deed is the single most common reason HMRC challenges the timing.
- Independent witnessing of signatures. A deed is usually witnessed; the witness's signature and date corroborate the execution date.
- The express statement of intention that s.142(1) IHTA 1984 (and s.62(6) TCGA 1992 where CGT relief is wanted) is to apply, signed by all relevant persons. HMRC's Instrument of Variation Checklist (form IOV2) exists precisely so you can self-check that the statement and other conditions are present before you submit.
- The date of death on the death certificate, so the two-year window can be calculated on the face of the file.
- A contemporaneous attendance note or covering letter from the solicitor or practitioner confirming the date of execution — useful corroboration if the deed itself is ever questioned.
- Proof of consideration absence — nothing on file suggesting any party was paid to agree, which would breach s.142(3).
Completing the IOV2 checklist is not legally compulsory, but it is strongly advisable: it walks through each statutory condition, and a completed checklist on file is good evidence that the variation was made correctly and on time.

Frequently asked questions
Does the two-year deadline run from the date of death or the grant of probate?
From the date of death. Section 142(1) IHTA 1984 says "within the period of two years after a person's death." Probate, estate valuation, and distribution dates are all irrelevant to the deadline. A slow grant simply shortens the time you have left.
What happens if I miss the two-year window?
You lose the ability to "read back" the redirected gift. You can still give the money away, but it becomes a gift from you, not from the deceased — a Potentially Exempt Transfer that only leaves your estate for IHT if you survive seven years from the date of the gift. No estate-level reading-back is available after two years.
Can I make a deed of variation before probate is granted?
Yes. There is no requirement to wait for the grant. Beneficiaries can agree and execute a valid variation at any point inside the two years. In practice you usually need the estate figures to draft it properly, but the grant is not a legal precondition.
What is the statement of intent and why does it matter?
Section 142(2) requires the instrument to contain a statement, made by all the relevant persons, that they intend s.142(1) to apply. Without that statement the reading-back relief is simply not available — even if every other condition is met. If you also want the CGT relief, add a corresponding statement that s.62(6) TCGA 1992 is to apply.
What proof does HMRC want that the variation was made in time?
A clearly dated and witnessed instrument, the express statement of intent, the death certificate showing the date of death, and ideally a completed IOV2 checklist plus a covering note confirming the execution date. The most common challenge is an undated deed, so date every signature.
Does redirecting money to my children save inheritance tax on the estate?
Not by itself — switching who receives a sum within the family does not change the IHT on the deceased's estate. The saving comes when reading-back avoids a taxable gift from the original beneficiary, or when redirecting to a spouse, charity, or direct descendant unlocks a relief such as spouse exemption, the reduced charity rate, or the residence nil-rate band.
