A Complete Guide to Stamp Duty Reliefs for Probate Properties: Exemptions, Reliefs, and the Schedule 4ZA Inherited-Interest Carve-Out

The default assumption that any inherited property transaction attracts SDLT is wrong. Most probate-related transfers fall inside one of the FA 2003 exemptions or reliefs; only a narrow subset (beneficiary buy-outs of co-inherited shares for consideration; sales by personal representatives to third-party buyers; transfers in partial discharge of a pecuniary legacy where the property exceeds the legacy value; corporate acquisitions outside the Schedule 6A relief) generate a substantive SDLT charge. The relief architecture is materially different from the transfer-type taxonomy and the two lenses are best read together; this page covers the relief axis and cross-links the existing transfer-type guide for the mechanics.

For the five-transfer-type taxonomy (assents, deeds of variation, transfers in discharge of legacies, sales by personal representatives, beneficiary buy-outs) and the additional dwellings surcharge interaction on each, see our SDLT on probate property transfers page. For the broader SDLT refund landscape including refund routes where surcharge has been paid in error on a probate acquisition, see our stamp duty refund whole-landscape umbrella. For the dedicated decision tree across the six refund routes within the surcharge family, see our 5% SDLT surcharge refund claims page.

The six relief and exemption architectures at a glance

• Schedule 3 paragraph 3A: the assent exemption (no SDLT charge on a genuine assent to a beneficiary entitled under will or intestacy).
• Schedule 3 paragraph 4 with Schedule 4 paragraph 8A: the deed-of-variation exemption (no SDLT charge on a section 142 IHTA 1984-compliant deed of variation within two years of death).
• Schedule 6A: the property-trader relief (full SDLT relief for a corporate property trader acquiring a deceased's dwelling from personal representatives, subject to onward-sale, refurbishment, and non-occupation conditions).
• Schedule 4ZA paragraph 16: the inherited-interest carve-out from the additional dwellings surcharge (50% share threshold; three-year temporal window).
• Section 49 chargeable-consideration analysis: for beneficiary buy-outs of inherited shares (SDLT computed on the equality money plus assumed debt).
• Schedule 4A interaction: non-natural-person 15% flat rate for corporate or partnership acquirers from personal representatives.

The Schedule 3 paragraph 3A assent exemption

FA 2003 Schedule 3 paragraph 3A reads: 'The acquisition of property by a person in or towards satisfaction of his entitlement under or in relation to the will of a deceased person, or on the intestacy of a deceased person, is exempt from charge.' The exemption operates by removing the assent from the SDLT charge entirely; it is structurally different from the no-chargeable-consideration analysis under section 49 (which removes the SDLT charge by reference to consideration value) because the paragraph 3A exemption applies even where there is some consideration in the form of assumed secured debt.

The conditions in operational terms are: the acquisition must be by a person entitled under the will (a beneficiary named in the will, a residuary beneficiary taking the residue, a beneficiary under a class gift such as 'my children') or on intestacy (a person entitled under the rules of distribution where there is no valid will); the acquisition must be in or towards satisfaction of that entitlement (not in discharge of a separate debt owed by the personal representatives to a third party); and the documentation must reflect the assent character (typically Land Registry form AS1 with no monetary consideration recorded, signed by the personal representatives as transferors and the beneficiary as transferee).

A genuine assent is also not a notifiable transaction under FA 2003 section 77, so no SDLT return is required. The Land Registry transfer is filed; no SDLT1 is filed. The 5% additional dwellings surcharge does not apply because the surcharge piggybacks on standard residential SDLT, which is itself nil where the assent is outside the charge. The non-UK resident 2% surcharge under Schedule 9A is similarly inapplicable. The beneficiary does not pay SDLT in any form on the assent, regardless of how many residential properties they already own.

The Schedule 3 paragraph 4 deed-of-variation exemption

FA 2003 Schedule 3 paragraph 4 exempts variations of testamentary dispositions that satisfy the conditions in IHTA 1984 section 142: the variation must be in writing; executed within two years of death; signed by the variating beneficiaries; and not made for consideration in money or money's worth other than consideration consisting of the making of another variation. The exemption operates by treating the property as if it had passed under the original will to the new beneficiary, so the SDLT analysis runs as if the original beneficiary had never been entitled and the new beneficiary takes by direct entitlement under the will.

FA 2003 Schedule 4 paragraph 8A provides a parallel chargeable-consideration carve-out for variations that fail the paragraph 4 condition through containing consideration other than the variation of another disposition. Even where the deed is outside Schedule 3 paragraph 4 (because consideration was given), Schedule 4 paragraph 8A ensures the variation itself is not chargeable consideration: the SDLT charge falls on the variation-as-consideration only to the extent of the actual consideration paid for the variation, not on a deemed market value. The architecture is protective: the deed has to satisfy all the formalities for the headline exemption, but the chargeable-consideration carve-out provides a safety net where the formalities are not met.

Common failure modes for the headline exemption: the deed is executed more than two years after death (outside the section 142 window); the deed is not signed by all variating beneficiaries (typically because a minor or otherwise legally-incapable beneficiary cannot sign); the deed contains consideration other than the variation of another disposition (e.g. one beneficiary pays cash to another for the redirection). Where the headline exemption fails, the Schedule 4 paragraph 8A carve-out limits the SDLT exposure to the actual consideration paid, but the deed loses its IHT-neutrality benefit which is typically the primary motivation for the deed in the first place.

The Schedule 6A property-trader relief

FA 2003 Schedule 6A provides full SDLT relief for a property trader acquiring a residential dwelling from the personal representatives of a deceased individual. The relief is narrow and conditional. The trader must be a company, an LLP, or a partnership composed of companies; sole traders, individuals, and individual-member partnerships do not qualify. The deceased must have occupied the dwelling as their main or only residence at some point in the two years preceding death; this excludes investment properties and second homes that the deceased did not occupy. The trader must sell the dwelling within three years of acquisition. The trader must not refurbish the dwelling above the permitted amount (the greater of £10,000 or 5% of the acquisition price, capped at £20,000). The trader must not grant a lease or licence over the dwelling. The trader must not permit principals, employees, or connected persons to occupy the dwelling.

The relief is claimed on the SDLT return at the time of acquisition. Breach of any condition post-acquisition triggers HMRC clawback under FA 2003 Schedule 10: the trader becomes liable for the SDLT that would have been charged at the original effective date plus interest from that date. The clawback liability is asset-specific and survives a subsequent sale of the property; a buyer of the trader's company can inherit the contingent clawback exposure. HMRC's enquiry posture is firm and the documentation pack (deceased's residential occupation evidence; refurbishment cost records; non-occupation evidence) is the load-bearing protection.

The Schedule 4ZA paragraph 16 inherited-interest carve-out

The most operationally important relief in this cluster. FA 2003 Schedule 4ZA paragraph 16 disregards an inherited interest in a dwelling for the additional dwellings surcharge analysis on a separate property purchase, subject to two conditions.

Condition one: the buyer's beneficial share in the inherited interest must not exceed 50%. A tenant-in-common share of more than half does not qualify; a coparcener share of more than half does not qualify; a sole-beneficiary 100% inheritance does not qualify. The threshold is fixed at 50%; a 51% share is outside the carve-out.

Condition two: the buyer is treated as not having the inherited interest only during the period of three years beginning with the date of inheritance. After three years from the date of inheritance, the inherited share is back in the dwelling count and the surcharge analysis on any subsequent purchase. The three-year clock runs from the date of inheritance (typically the date of death where the property vests automatically, or the date of assent where it vests on assent), not from the date of any subsequent purchase.

Note on the £40,000 question. Widely-circulated adviser commentary refers to a triple-condition on paragraph 16 with a £40,000 value cap on the inherited interest. The legislation does not support this. Paragraph 16 contains no monetary value threshold on the inherited interest itself. The £40,000 figure that appears in other Schedule 4ZA paragraphs is a separate minimum-consideration threshold on the new transaction (a transaction with chargeable consideration of less than £40,000 is outside the surcharge entirely), not a value cap on the inherited interest under paragraph 16. The widely-circulated triple-condition framing is an error; the carve-out is two-condition (share + temporal window) only.

Worked decision tree: four scenarios

Scenario 1 (success): Patel inherits a 50% share of a £600,000 family home from a parent on 15 March 2024. Patel and Patel's sibling each hold 50% as tenants in common. Patel is buying a £450,000 main residence in May 2026. The 50% share is at the threshold and within paragraph 16 (the test is 'does not exceed 50%', so exactly 50% qualifies). The 14-month period since the date of inheritance is within the three-year window. Paragraph 16 disregards the inherited share; the additional dwellings surcharge does not apply to the May 2026 main residence purchase.

Scenario 2 (failure, share too large): Singh inherits a 100% interest in the deceased aunt's London flat on 1 January 2025. Singh is buying a £700,000 main residence in October 2026. The 100% inheritance is outside paragraph 16 (share exceeds 50%). The inherited flat counts as an owned residential dwelling for the surcharge analysis on the October 2026 purchase. The 5% surcharge applies (£35,000 of additional SDLT) unless the October 2026 purchase qualifies as a replacement of main residence under Schedule 4ZA paragraph 3(7) with the sale of any previous main residence completing within three years.

Scenario 3 (failure, temporal window expired): Mawell-Estate trustees inherited a 40% share of a country property on 20 June 2022. Mawell-Estate is acquiring a £350,000 buy-to-let in September 2026 (Mawell-Estate already holds a main residence). The 40% share is within the paragraph 16 share threshold. The four-year period since inheritance is outside the three-year temporal window; paragraph 16 no longer disregards the inherited share. The inherited share counts as an owned dwelling for the surcharge analysis. The 5% surcharge applies to the September 2026 acquisition unless other Schedule 4ZA provisions remove it.

Scenario 4 (success): Patel-and-siblings each inherited a 25% share of a £800,000 family home on 8 November 2024 (four siblings as equal tenants in common). Patel is buying a £550,000 main residence in March 2026. The 25% share is within the threshold. The 16-month period is within the three-year window. Paragraph 16 disregards the inherited share; the additional dwellings surcharge does not apply to the March 2026 purchase. The same analysis applies independently to each sibling's separate main residence acquisition within the three-year window.

Beneficiary buy-out chargeable-consideration analysis (section 49)

Where one beneficiary buys out another's share of an inherited property, the chargeable consideration for SDLT under FA 2003 section 49 is the amount paid by the buying beneficiary to the other beneficiaries (equality money) plus the assumed share of any outstanding mortgage on the property. The SDLT charge is computed on this chargeable-consideration figure, not on the underlying value of the property or the value of the share acquired. The 50% share threshold and the three-year temporal window in Schedule 4ZA paragraph 16 apply to the inherited share itself: the carve-out can disregard the inherited share for the additional-dwellings analysis on the buy-out, but only where the share and timing conditions are met.

Worked example. Three siblings each inherit a 33% share of a £450,000 family home on 12 February 2025. The Patel-sibling buys out the other two siblings on 20 April 2026 for £150,000 cash plus assumes their 67% share of a £90,000 mortgage outstanding on the property (£60,000 of assumed debt). Chargeable consideration under section 49 is £210,000 (£150,000 equality money plus £60,000 assumed debt). SDLT is computed on £210,000 at the standard residential rates. The additional dwellings surcharge applies to the buy-out if the Patel-sibling already owns another residential dwelling (separately from the 33% inherited share). The Schedule 4ZA paragraph 16 carve-out on the inherited 33% share itself is within both conditions (33% is below 50%; 14 months is within three years) so the 33% inherited share does not count as an additional dwelling for the surcharge analysis on the buy-out; but the buy-out itself is the acquisition of the further 67% share and the surcharge tests whether the Patel-sibling already owns other dwellings outside the inherited interest.

Schedule 4A non-natural-person 15% flat rate interaction

FA 2003 Schedule 4A imposes a 15% flat rate of SDLT on acquisitions of high-value residential dwellings (over £500,000) by non-natural persons (companies, collective investment schemes, partnerships including a corporate partner). Where the personal representatives sell the dwelling to a corporate acquirer, the Schedule 4A 15% rate applies unless the acquisition falls within a relief category. The relevant categories for probate transactions are: the property-rental business relief; the property-developer relief; and the property-trader relief under Schedule 6A. The Schedule 6A relief route is typically the most-relevant for genuine PR-buyback transactions where the trader intends an onward sale within three years.

For corporate acquirers outside the Schedule 4A relief categories, the 15% flat rate is materially higher than the standard residential rates plus the 5% additional dwellings surcharge alternative (which for a £600,000 acquisition would total around 17% to 19% depending on band-by-band computation, so Schedule 4A's 15% is sometimes lower in absolute terms but is computed differently and may interact with ATED (the Annual Tax on Enveloped Dwellings) for ongoing holding-cost purposes). Pre-completion analysis of the rate position and the relief eligibility is critical; structuring decisions made at the heads-of-terms stage are typically irreversible at the SDLT-return stage.

Cross-statute interaction: IHT and CGT

The SDLT analysis sits alongside the IHT and CGT positions on inherited property. The deceased's estate takes the property at market value on death (the death-uplift), so any pre-death gain is washed out for CGT purposes under TCGA 1992 section 62(4). The beneficiary's CGT base cost is that uplifted market value; subsequent disposal is taxed on the gain since the death valuation. SDLT on the assent is nil where the Schedule 3 paragraph 3A exemption applies. IHT may be charged on the estate at death depending on the nil-rate band, residence nil-rate band, and the spouse/civil-partner exemption position. The three taxes are independent: SDLT exemption on the assent does not affect IHT exposure on the estate; IHT exposure does not affect the CGT base-cost uplift; CGT base cost on the beneficiary's later disposal does not affect SDLT on any further acquisition.

Where the property is held on a life-interest trust and the life tenant dies, the property typically vests automatically in the remainder beneficiary. There is generally no chargeable consideration on the vesting (the remainderman takes under the trust, not as a purchaser), so no SDLT charge arises. IHTA 1984 section 49 deems the life tenant beneficially entitled to the trust property during the life interest, so the property forms part of the life tenant's estate for IHT purposes. The remainderman's CGT base cost is the death-date market value under TCGA 1992 section 62(4).
