Deed of Variation Deadline UK (2026): The 2-Year Time Limit and What Happens If You Miss It

The 2-year deadline is the central rule governing the IHT and CGT effectiveness of a deed of variation: (1) THE STATUTORY DEADLINE: IHTA 1984 s.142(1) — a deed of variation must be made 'within the period of two years after the death' for it to be treated as if the deceased had made the new disposition in their will or intestacy. TCGA 1992 s.62(6) — the same 2-year window applies for the variation to be treated as a disposal made by the deceased at date of death (rather than a disposal by the beneficiary at the date of the variation); (2) WHEN THE 2 YEARS RUNS FROM: the 2 years runs from the DATE OF DEATH. CRITICAL: it does NOT run from: (a) the date of the grant of probate or letters of administration; (b) the date the estate was distributed to the beneficiary; (c) the date the beneficiary received or spent their inheritance; (d) the date the beneficiary became aware of the death or the will. PRACTICAL IMPLICATION: even if probate takes 12 months, and the estate is distributed 18 months after death, the 2-year window from the date of death is still only 2 years from the date of death. A variation made at month 25 from the date of death is too late — regardless of when the estate was administered; (3) CAN THE DEADLINE BE EXTENDED: NO. The 2-year period in IHTA 1984 s.142 is an absolute statutory deadline. Unlike many statutory time limits, there is no provision allowing HMRC or any court to extend it. There is no discretion. There is no hardship or exceptional circumstances exception. Once 2 years have passed from the date of death, a deed of variation cannot achieve the backdated IHT or CGT treatment under s.142; (4) EXAMPLE: person dies on 05 January 2025. The 2-year window closes on 04 January 2027. Any deed of variation to qualify under IHTA 1984 s.142 must be executed by all relevant parties and be in correct form by 04 January 2027; (5) CHECKING THE DATE IN PRACTICE: the date of death appears on the death certificate and on the grant of probate. Beneficiaries and their advisers should identify the 2-year deadline immediately after the death and enter it in their diary — do not wait for the estate to be distributed before thinking about variations.

A deed of variation executed within 2 years can significantly alter the IHT and CGT position of the estate: (1) HOW IT WORKS — THE LEGAL FICTION: IHTA 1984 s.142(1) and TCGA 1992 s.62(6) create a legal fiction: the variation is treated as if the deceased had made the new disposition in their will or intestacy at the date of death. For IHT and CGT purposes ONLY, the estate is recalculated as if the new gifts were the original gifts. Note: the variation is NOT treated as the deceased's for all purposes — it is a legal fiction limited to IHT and CGT; (2) IHT BENEFITS — COMMON USES: (a) redirecting to a surviving spouse: a beneficiary who inherits under the will can redirect their share to the surviving spouse — the spouse exemption (IHTA 1984 s.18) applies, reducing the first death estate's IHT; (b) redirecting to charity: the charitable exemption (IHTA 1984 s.23) applies, reducing IHT on that portion; (c) redirecting to a NRB trust: redirecting part of the estate to a discretionary trust (up to the NRB) can make use of the deceased's NRB that might otherwise be wasted; (d) redirecting from a spouse to children: bypassing the surviving spouse (who has a large estate of their own) to pass directly to children — reducing the second death IHT exposure; (3) CGT BENEFIT: if the beneficiary has inherited assets that have already appreciated since the date of death, a variation can redirect them to another beneficiary without triggering CGT — because the new recipient is treated as having acquired at the death value (not the increased value at the date of variation); (4) THE 'STATEMENT' REQUIREMENT: for the variation to achieve IHT benefit, the deed must contain a statement that IHTA 1984 s.142(1) applies (or words to that effect). For CGT benefit, the deed must contain a statement that TCGA 1992 s.62(6) applies. A deed executed without these statements achieves no backdated tax relief (though it may still be effective as an outright gift); (5) NO CONSIDERATION: the variation must be for no consideration — if a beneficiary receives money or other value in exchange for varying the inheritance, the s.142 treatment is denied; (6) WHO MUST SIGN: all beneficiaries whose interests are being varied must sign. The personal representatives only need to sign where the variation results in a higher IHT liability.

Missing the 2-year deadline has serious tax consequences: (1) AFTER 2 YEARS — WHAT HAPPENS: a beneficiary who wants to redirect their inheritance to another person after the 2-year deadline has passed cannot use a deed of variation to achieve backdated IHT/CGT treatment. Instead, the redirection is treated in the normal way as a gift from the beneficiary to the new recipient; (2) IHT CONSEQUENCES OF A LATE GIFT: the late gift from the beneficiary is a potentially exempt transfer (PET) for IHT purposes (IHTA 1984 s.3A). For the gift to be IHT-exempt, the beneficiary must survive 7 years from the date of the gift. If the beneficiary dies within 7 years, the gift becomes chargeable. The gift is also included in the 7-year cumulation for calculating IHT on any death estate; (3) CGT CONSEQUENCES OF A LATE GIFT: if the beneficiary gifts an asset (e.g. inherited property or shares) to another person after the 2-year window, this is a disposal for CGT purposes (TCGA 1992 s.17 — at market value for connected persons or for gifts). The gain is calculated from the inherited (probate) value to the current market value at the date of the gift. CGT is payable on the gain at the beneficiary's marginal rate (10% or 20% for assets; 18% or 24% for residential property not qualifying for PPR); (4) THE CONTRAST: within 2 years → the variation wipes out the gain between death value and variation date; after 2 years → the beneficiary is personally liable for CGT on the gain between death value and gift date. This can be a very large tax difference if the asset has appreciated significantly; (5) IS THERE ANY RELIEF: gift hold-over relief (TCGA 1992 s.260) may be available in some cases (where the gift is to a discretionary trust, or the trust is a relevant property trust); business asset hold-over relief (TCGA 1992 s.165) may apply to qualifying business assets. But these are not available for straightforward gifts of cash or residential property; (6) PRACTICAL ADVICE: if the 2-year deadline is approaching and a variation is being considered, act immediately. Do not wait for the estate to be fully administered. A simple deed of variation can be executed before the estate is distributed.

The procedure for a deed of variation is relatively straightforward, but strict requirements must be met for it to be effective: (1) THE FORM: a deed of variation is a formal document — it must be executed as a deed (Law of Property (Miscellaneous Provisions) Act 1989 s.1 — signed; witnessed; and expressed to be a deed). The document should: (a) identify the deceased by full name and date of death; (b) identify the original disposition being varied (the clause in the will or the intestacy entitlement); (c) describe the new disposition (what is being redirected; to whom; in what amount or proportion); (d) contain the IHT statement: 'The parties confirm that IHTA 1984 s.142(1) shall apply to this variation'; (e) contain the CGT statement (if needed): 'The parties confirm that TCGA 1992 s.62(6) shall apply to this variation'; (f) be signed by each beneficiary whose interests are being varied; (g) be dated; (2) WHO MUST SIGN: (a) every beneficiary who is giving up or reducing their entitlement must sign; (b) beneficiaries gaining under the variation do not have to sign (though it is good practice); (c) the personal representatives must sign only if the variation results in additional IHT being payable by the estate (they must agree to pay the additional IHT); (d) if the new recipient is a trust, the trustees must also sign to accept the gift; (3) NOTIFICATION TO HMRC (IF IHT INCREASES): if the variation increases the amount of IHT payable by the estate, the personal representatives must notify HMRC within 6 months of the date of the variation (IHTA 1984 s.142(2)). Failure to notify within 6 months does not invalidate the variation — but HMRC must be notified as soon as possible; (4) WHEN NO HMRC NOTIFICATION IS NEEDED: if the variation reduces IHT (or has no effect on IHT), HMRC does not need to be notified separately — though the revised IHT position should be reflected in any corrective accounts filed; (5) CAN A DEED OF VARIATION BE USED MORE THAN ONCE: yes — multiple variations of the same estate can be made, provided each variation meets the requirements and the combined effect is not treated as a series of linked transactions; however, the same interest cannot be varied more than once (each beneficiary's inherited interest can be varied once only under IHTA 1984 s.142(4)).

The scope of what can be redirected by a deed of variation is important to understand: (1) WHAT CAN BE VARIED: (a) specific legacies under the will (named assets); (b) pecuniary legacies (cash gifts); (c) residuary entitlements (the beneficiary's share of the residue); (d) intestacy entitlements (the share a beneficiary inherits under the intestacy rules); (e) property that passed to a spouse by survivorship from a joint tenancy — BUT only if the surviving joint tenant agrees to redirect that property. The surviving joint tenant has an outright property right; they can redirect it by variation within 2 years of the death; (2) WHAT CANNOT BE VARIED UNDER s.142: (a) pension death benefits: DC pension pots are held in trust by the pension trustees and pass outside the estate under the expression of wishes. They are NOT part of the estate and cannot be redirected by a deed of variation. To redirect pension death benefits, the beneficiary would need to disclaim or request the pension trustees to change the nomination — but this is NOT a deed of variation and does not get the backdated IHT treatment; (b) life assurance policies written under trust: like pensions, these pass outside the estate and cannot be varied under s.142; (c) assets in a trust set up by the deceased before death: the trust assets were not part of the deceased's estate and are not subject to the will or intestacy; (d) assets that were gifted by the deceased before death — PETs that have already been made cannot be 'un-made' by a deed of variation; (3) PARTIAL VARIATIONS: a beneficiary can vary only part of their entitlement and retain the rest. EXAMPLE: a beneficiary inherits £200,000 of residue. They vary £80,000 to a grandchild and retain £120,000. Only the varied £80,000 gets the backdated IHT treatment; (4) DEED OF VARIATION VS DISCLAIMER: a disclaimer is different — the beneficiary simply refuses to accept the gift in its entirety, and it passes as if the beneficiary had predeceased. A disclaimer cannot redirect to a specific named person; a deed of variation can. A disclaimer must be made before the beneficiary accepts any benefit from the inheritance (there is no 2-year time limit for disclaimers — but the earlier the better).
