Two decades. That is the irreducible commitment that comes with notifying an option to tax under Schedule 10 of the Value Added Tax Act 1994. The option converts the default-exempt grant of an interest in or right over commercial property into a standard-rated 20% supply, and unlocks input-tax recovery on the acquisition, refurbishment, and professional costs that sit behind it. In exchange, the opter accepts a 20-year statutory lock on every future grant of the relevant interest under Sch 10 paragraph 25 (verbatim heading 'Revocation of option: lapse of more than 20 years since option had effect'), with only the narrow 6-month cooling-off route at paragraph 23 and the 6-year-no-interest route as exits before the clock expires.

This page is the framework pillar of the option-to-tax cluster. It covers the architectural decision: what binding the opter for two decades actually means across an asset's life, who and what the option binds, when HMRC's prior permission is required before the election can be made, how the real estate election under paragraph 21 changes the unit of analysis from per-property to per-entity, and how the Capital Goods Scheme runs as a 10-year shadow behind every opted capital asset. The operational mechanics (the form VAT1614A, the 30-day notification window, the cooling-off mechanic, the disapplication operational categories) live on our companion VAT option to tax mechanics and revocation page. The revocation, TOGC option-matching, and paragraph-by-paragraph disapplication walks live on dedicated sibling pages cross-referenced at the foot.

The architectural problem the option solves

The grant of any interest in or right over land, including a lease, a licence to occupy, or a freehold transfer, is exempt from VAT under VATA 1994 Sch 9 Group 1 Item 1 (subject to 14 statutory carve-outs at paragraphs (a) to (n) of that Item, including the self-storage carve-out at paragraph (ka) inserted by FA 2012 Sch 26). For ordinary commercial-property letting (offices, retail units, industrial sheds, warehouses, mixed-use buildings), the exemption is the default position.

Exemption sounds neutral but is not. Exempt supplies do not allow input-tax recovery on costs that relate to them. A commercial landlord acquiring a £3m office at 20% VAT, refurbishing for a further £600,000 plus £120,000 VAT, paying £80,000 plus £16,000 VAT in agent and professional fees, is sitting on £736,000 of irrecoverable input VAT under the default exempt position. For long-life capital assets with material input VAT on the development cost stack, the irrecoverability is a structural problem that the option to tax exists to solve.

The architecture of the solution is straightforward in design but exacting in operation. Schedule 10 paragraph 2 (verbatim heading 'Effect of the option to tax: exempt supplies become taxable') provides that where the option has been exercised and a grant is made by the opter (or a relevant associate) while the option has effect, the grant does not fall within Group 1 of Schedule 9. The supply moves from exempt to standard-rated; the opter charges 20% VAT on rent and on the eventual sale proceeds; the input VAT on the cost stack becomes recoverable to the extent the property is used to make taxable supplies. The architectural cost, embedded in paragraph 25, is the 20-year minimum life of the election before voluntary revocation becomes available.

What you bind and what you do not bind

The option binds the opter and the relevant interest in the land, not the building and not the lease. This three-element distinction (opter, relevant interest, land) is the single most-misunderstood feature of the regime.

The opter is the person who exercises the option: a natural person, a company, a partnership, the representative member of a VAT group, or a trustee. Where a body corporate exercises the option, any relevant associate (broadly, a group member or person under common control) is also bound. A partnership option binds the partnership as a VAT entity even where the underlying partners change.

The relevant interest is the legal interest in the specific land or building (or structurally-separate part of a building) over which the option is exercised. The interest is the unit of analysis, not the lease to a particular tenant. Two consecutive tenants of the same opted unit are both supplied under the same election.

What the option does not bind is the building itself. When the opted property is sold, the option does not pass to the buyer. The buyer makes an independent decision: opt, accept exempt-supply status, or rely on disapplication under paragraphs 5 or 6. Three consecutive owners can hold the same building with three different VAT positions.

The 20-year lock at Schedule 10 paragraph 25

The 20-year statutory lock is the defining structural feature of the regime. Paragraph 25 of Schedule 10 (verbatim heading 'Revocation of option: lapse of more than 20 years since option had effect') opens the principal voluntary revocation route only once the time that has lapsed since the day on which the option had effect is more than 20 years. The clock starts on the effective date stated in the VAT1614A notification (typically the date of the underlying decision, with backdating possible only within the 30-day notification window and within tightly-defined belated-notification cases). Before the clock expires, the only voluntary withdrawal routes are the 6-month cooling-off period at paragraph 23 (verbatim heading 'Revocation of option: the "cooling off" period') and the narrower route where the opter has not held any relevant interest in the property for at least 6 years.

The architectural consequence of the lock is that the opt decision must be made in view of a 20-year horizon, not the immediate input-tax recovery prize. The decision-maker is committing to charging 20% output VAT on every future rental supply and every future sale of the property for at least two decades, regardless of how tenant mix changes, how the property is repurposed within its planning consent, or how the broader market shifts.

Three operational implications follow. First, the lock survives changes in tenant covenant. A commercial property opted in 2026 with VAT-registered taxable occupiers (where the VAT charge is cashflow-neutral) may by 2036 be let to substantially-exempt occupiers (where the VAT charge is an absolute cost depressing the rent the tenant will accept); the opter is still required to charge 20% VAT for at least another decade. Second, the lock interacts with the Capital Goods Scheme. CGS adjustments under SI 1995/2518 regulations 112 to 116 run for 10 intervals; opting and then becoming exposed to a CGS clawback mid-cycle (because of use changes) is one of the largest sources of unexpected VAT cost on commercial property portfolios. Third, the lock affects exit timing. Where the lock has expired, the opter has the option to revoke under paragraph 25 (form VAT1614J, subject to conditions in HMRC's public notice). Where the lock has not expired, exit via TOGC (with the buyer opting in parallel) or via standard-rated sale is the practical route; voluntary revocation is unavailable.

The 20-year framing also disciplines the pre-opt decision. A landlord considering opting on a property they intend to hold for 5 years should be confident the option is right for the property's full economic life, not just their holding period: when the property is sold, the buyer is not bound by the seller's option, but the seller's option survives on the seller's books even after the sale (until either the 20-year clock expires under paragraph 25 or the no-interest-for-6-years route opens). The implication is that the option's downstream effects on the seller's own VAT-group recovery position can outlive the property holding itself.

The election mechanics in 90 seconds

Operational mechanics are covered in depth on the companion VAT option to tax mechanics and revocation page. In summary: the opter takes the underlying decision (a board minute, a written file note, or a contemporaneous email to the VAT adviser), then notifies HMRC on form VAT1614A ('Tell HMRC about an option to tax land and buildings') within 30 days. HMRC issues a date-stamped acknowledgement, which together with the underlying decision evidence becomes the file the opter retains for the life of the option (20-plus years, plus a further 6 years after eventual revocation). Late notification is sometimes accepted under HMRC's belated-notification practice in Notice 742A section 4.2 where contemporaneous evidence supports the earlier decision date and output / input tax has been treated consistently.

The unit of election is the relevant interest in the property as defined by the opter in the VAT1614A. A structurally-separate part of a building (single floor, single suite, single unit) can be opted independently; an arbitrary tenant-by-tenant election within a multi-occupier floor cannot. Where the property has a residential element, paragraph 5 automatically disapplies the option on the dwellings, and the opter accounts for the commercial-versus-residential apportionment on residual input VAT.

Prior permission under Schedule 10 paragraphs 28 to 30

Most option-to-tax notifications proceed under HMRC's automatic permission framework set out in Notice 742A. Paragraph 28 of Schedule 10 (verbatim heading 'Pre-option exempt grants: requirement for prior permission before exercise of option to tax') reserves a category of fact patterns where prior permission must be obtained from the Commissioners before the option can be exercised at all. The statutory test: prior permission is required where the opter (or a relevant associate) has made an exempt grant of the same land within the period of 10 years before the proposed effective date, and the conditions for automatic permission in the public notice are not met.

The conditions for automatic permission, set out in Notice 742A section 5, allow the opter to bypass the prior-permission route where one of several alternative conditions is satisfied: the only pre-option exempt grant was a freehold acquisition and no input tax was incurred on the acquisition; the value of all pre-option exempt grants of the land is below de-minimis thresholds; the opter is in a partial-exemption position where the input tax recovered on pre-option exempt grants was already below de-minimis levels. Where none of these automatic-permission routes is available, paragraph 28(1)(b) requires the opter to apply to the Commissioners for prior permission on form VAT1614H ('Apply for permission to opt to tax land or buildings').

The grant of permission is not automatic on application. The Commissioners must refuse permission unless satisfied that 'there would be a fair and reasonable attribution of relevant input tax to relevant supplies', having regard to: (a) the total value of exempt supplies made before the effective date of the proposed option; (b) the expected value of taxable supplies after the effective date; and (c) the input tax incurred (or expected to be incurred) on the land. The substantive question is whether the prospective input-VAT recovery is proportionate to the post-option taxable economic activity, or whether the opter is effectively trying to retro-engineer recovery on substantively-exempt economic activity.

Practical application: a commercial landlord who has been letting an unopted commercial property at exempt rents for several years, then carries out a major refurbishment, and wants to opt to recover the refurbishment VAT, will typically need prior permission. The pre-option exempt grants are the historical rents; the input-tax-recovery prize is the refurbishment VAT. HMRC's decision will turn on whether the post-opt taxable rental supplies justify the recovery, or whether the structure looks like an attempt to backfill recovery on the previously-exempt holding period. Decision timelines run 30 to 90 days; refusal is not unusual on facts where pre-option exempt activity was material relative to the post-option proposition.

Two further structural points. First, prior permission is required before the option is exercised, not after notification. A VAT1614A filed before VAT1614H permission has been granted is invalid; the option is not in force; any input-VAT recovery taken under it is recoverable by HMRC with interest and a penalty risk under FA 2007 Schedule 24. Second, the 10-year pre-option exempt grants window is calculated from the proposed effective date backward, not from the date of notification. Opters often miscalculate this window by counting back from notification, leading to incorrect automatic-permission self-assessment.

The real estate election (Schedule 10 paragraph 21)

A taxable person with a portfolio acquisition strategy can move the unit of election from per-property to per-entity by making a real estate election under paragraph 21 (verbatim heading 'Real estate elections: elections to opt to tax land subsequently acquired'). The election operates as a forward-looking option in respect of every relevant interest in any building or land that the electing person (and, in a VAT group, the relevant group members at the time of acquisition) acquires after the date the election is made. The administrative consequence is that each post-election acquisition is treated as automatically opted from the acquisition date, with no per-property VAT1614A required.

The notification mechanic for the real estate election uses form VAT1614E ('Opting to tax land and buildings: notification of a real estate election'). Statutory notification window: within 30 days of the election being made (or such longer period as the Commissioners allow on application).

Each property captured by the election is still treated as having a separate underlying option with its own 20-year clock running from that property's acquisition date. The election does not bunch the 20-year clocks. A property acquired in 2026 has a clock to 2046; a property acquired in 2030 has a clock to 2050; the opter cannot revoke under paragraph 25 on the 2026 property until the 2026 clock expires regardless of what happens on the 2030 property.

The real estate election is materially harder to revoke than a per-property option. Paragraph 21(4) and (5) permit revocation only on Commissioner direction for failure to comply with information requests; the opter does not have a voluntary right to revoke the election going forward. A new property acquired after the election is automatically opted whether or not the opter prefers it not to be. The two operationally-relevant exceptions are: properties already opted before the election date are unaffected; and properties where the option is statutorily disapplied (paragraphs 5 dwelling, 6 recipient-certified residential, 12 developers-of-exempt-land anti-avoidance) operate as disapplied notwithstanding the election.

The election is most appropriate for institutional commercial-property vehicles whose acquisition strategy is consistently commercial. Landlords with mixed acquisition strategies (some commercial, some residential, some intended for owner-occupation) should not elect; the automatic sweep captures residential acquisitions which are then disapplied by paragraph 5, generating administrative complexity rather than relief.

The disapplication boundary at a glance

The option does not produce a taxable supply on every grant the opter makes; certain supplies are statutorily disapplied. Three distinct disapplication categories, walked in distinction-by-paragraph form on our dedicated sibling page on the paragraph 12 disapplication for residential conversion and connected matters:

  • Paragraph 5 (automatic dwellings disapplication). Where the building (or part) is designed or adapted, and intended for use, as a dwelling or number of dwellings, or solely for a relevant residential purpose (Group 5 Note 12 of Schedule 8 definition), the option has no effect on the grant. The disapplication is automatic; no certificate from the recipient is required.
  • Paragraph 6 (recipient-certified residential conversion). Where the recipient of the grant gives the grantor a certificate (form VAT1614D, 'Certificate to disapply the option to tax buildings') confirming intended use of the building as a dwelling or relevant residential purpose, the option is disapplied on that grant. This is the route most commonly used by residential developers acquiring commercial stock for permitted-development conversion.
  • Paragraph 12 (developers of exempt land anti-avoidance). The structurally most-complex disapplication, targeting cases where the grantor (or a development financier or connected party) intends or expects the land to be occupied for non-eligible purposes (broadly, substantially-exempt economic activity, with statutory exceptions for charitable use and de-minimis purposes). The connected-party 80%-recovery test is the operational lever: where a connected occupier cannot recover at least 80% of the VAT it pays, the option is treated as never having had effect on the supply. This catches commercial property opted to recover input VAT and then let to connected substantially-exempt occupiers (private medical or dental practices, banks, insurance brokers, education providers).

The three paragraphs are distinct: paragraph 5 is property-status-based (the building is designed as a dwelling), paragraph 6 is recipient-intention-based (the recipient certifies dwelling-conversion intent), and paragraph 12 is anti-avoidance (the grantor uses the option to recover input VAT on substantively-exempt activity). The companion disapplication page walks each in turn with worked-example facts.

The Capital Goods Scheme shadow

Every opted capital asset above the £250,000 (VAT-exclusive) threshold sits inside the Capital Goods Scheme for 10 intervals (10 years) under SI 1995/2518 regulations 112 to 116. The CGS overlay is the second structural feature of the regime that the opt-decision must contemplate.

Under the CGS, the initial recoverable proportion of input VAT at acquisition or first interval reflects the property's taxable-supplies use at that point. The recovery is then re-tested at each subsequent interval; where use has shifted toward exempt supplies (a new tenant cohort that is substantially exempt, a partial conversion to residential use, a revocation of the option) the recovery for that interval is reduced and the over-recovered input VAT is repaid in proportion. Where use has shifted toward taxable supplies (a previously-mixed-use property is fully repurposed for VAT-registered taxable tenants) additional recovery may be claimed.

The interaction between the option and the CGS is one of the most-misunderstood points in the regime. The option determines the property's classification (taxable or exempt) at each interval; the CGS determines how much of the original input VAT recovery is preserved at each interval. The two regimes work together over a 10-year horizon, with the option's 20-year lock providing the upper boundary on changes of position. A property opted in 2026 with £400,000 of acquisition VAT recovered, then disapplied under paragraph 12 in 2030 because a connected-party substantially-exempt tenant takes occupancy, faces a 6-year CGS clawback on approximately 60% of the original recovery (£240,000), payable in equal intervals across the remaining six years.

See our companion guide to the Capital Goods Scheme for property businesses for the full 10-interval mechanic, the calculation methodology, and the use-change trigger list.

The economic decision: input recovery against tenant cost and SDLT

The opt-decision sits at the intersection of three economic flows. First, input-VAT recovery: the prize. Second, tenant-borne output VAT: the cost (where tenants are substantially exempt, the VAT on rent depresses the rent achievable). Third, SDLT-on-VAT-inclusive consideration: the secondary cost on a future sale where TOGC is not available.

FlowQuantificationRecoverable?
Input VAT on acquisition20% of pre-VAT purchase priceYes, in full where taxable-use proportion is 100%
Input VAT on refurbishment20% of pre-VAT construction costYes, in full where taxable-use proportion is 100%
Input VAT on professional fees20% of pre-VAT legal, valuation, agency feesYes, in full where attributable to taxable supplies
Output VAT on rent (tenant absolute cost where exempt)20% of annual rent over the lock periodTo the tenant: recoverable if VAT-registered taxable; absolute cost if substantially exempt
SDLT on VAT-inclusive consideration (future sale, non-TOGC)5% of the 20% VAT addition above £250k threshold for commercialTo the buyer: not recoverable
CGS clawback risk over 10 yearsProportion of original recovery if use shifts toward exemptVariable; potentially up to 100% of recovery in extreme cases

The decision framework: opt where the input-VAT recovery prize, present-valued and net of expected CGS interactions, exceeds the present value of (a) the tenant-cost depression on rents over the 20-year lock and (b) the SDLT-on-VAT secondary cost on the expected exit. Where the prospective tenant covenant is taxable VAT-registered, the tenant-cost depression is zero and the decision is straightforward. Where the tenant covenant is mixed or substantially exempt, the rent-depression cost may exceed the recovery prize once the 20-year horizon is taken into account.

Worked example: Galloway Estate Limited 2026/27 portfolio decision

The reference scenario is an anonymised single-shareholder family company, Galloway Estate Limited, that has accumulated three commercial properties over a 15-year holding period. None of the three properties is currently opted. The properties:

  • An office building in a regional city centre, freehold, market value £6.5m, currently let to a single VAT-registered taxable corporate tenant on a lease with 18 months to run. Annual rent £350,000 exempt. Acquisition was in 2010 for £3.2m with no input VAT (TOGC). No refurbishment in the period.
  • A multi-let industrial estate, freehold, market value £4.8m, currently let to seven small-business tenants at staggered terms. Annual rent £290,000 exempt. Acquisition was in 2014 for £2.4m with input VAT of £480,000 not recovered (because the company was not opted). The recovery window has long since closed.
  • A mixed-use building (ground-floor retail unit with three flats above), freehold, market value £3.7m. The retail unit yields £85,000 annual rent (exempt); the flats yield £62,000 annual rent (exempt under Schedule 9 Group 1 with paragraph 5 protection regardless). Acquisition was in 2016 for £2.1m with input VAT of £125,000 on the commercial element not recovered.

Galloway is considering a portfolio-wide refurbishment over the next three years: £2.2m on the office, £1.6m on the industrial estate, £350,000 on the retail unit. Total programme £4.15m plus £830,000 input VAT.

The strategic question is whether to opt per-property (three separate VAT1614As, three 20-year clocks) or make a real estate election under paragraph 21 (one VAT1614E, automatic opt on every future commercial acquisition, 20-year clocks running per property from each acquisition date).

Per-property option analysis. Opting on the office unlocks £440,000 input VAT on the office refurbishment but commits Galloway to charging 20% VAT on rent for 20 years regardless of who the next tenant is (current tenant's lease has 18 months to run). Opting on the industrial estate unlocks £320,000 but three of the seven small-business tenants are below the VAT registration threshold, so the rent-depression cost on those tenants over the lock period is likely material. Opting on the retail unit of the mixed-use building unlocks £70,000 on the £350,000 refurbishment; the residential flats are protected by paragraph 5 automatic disapplication.

Real estate election analysis. If Galloway expects further commercial acquisitions in the next decade, the real estate election eliminates per-property notification burden. The cost is the loss of selectivity (a mixed-use acquisition with a residential element would be swept in, with paragraph 5 then doing the disapplication work).

Pre-opt structural check. None of the three properties has the kind of pre-option exempt grant history that fails Notice 742A section 5 automatic-permission conditions. Prior permission under paragraph 28 is not required.

Decision. Galloway opts on the office and the retail unit (clean tenant covenant, material recovery, no anti-avoidance trap), defers opting on the industrial estate pending a tenant-by-tenant rent-depression analysis against the £320,000 recovery, and does not make the real estate election (forward pipeline below the administrative-simplification threshold). Two VAT1614As filed; CGS overlay running from 2026 on both refurbishment projects; 20-year lock to 2046.

When the option is the wrong commercial answer

Six fact patterns where the answer is generally not to opt:

  • Substantially-exempt prospective tenant covenant. Banks, insurance brokers, GPs, dentists, private hospitals, charities, education providers: the rent-depression cost on each of these tenant types is material and the input-VAT recovery prize rarely survives the 20-year lock period economics.
  • Connected-party occupier where the connected occupier is substantially exempt. Paragraph 12 voids the option on the supply; the input-VAT recovery is treated as if the option had never been made, with interest and penalty exposure. Restructuring the occupier into an unconnected operating company is the cleaner alternative.
  • Short-term hold with sale on the horizon. Pre-registration input tax under SI 1995/2518 regulation 111 may cover the input VAT recovery on a short hold without requiring the 20-year commitment. The decision framework changes substantially where the property is acquired with a sale exit inside the first 6 to 12 months.
  • Residential-conversion plan where Schedule 8 Group 5 zero-rate is in view. Where the building is being acquired for conversion into a single dwelling (Sch 8 Group 5 first-grant-of-major-interest zero-rate eligible), the construction-services VAT is recoverable through the zero-rated onward sale without requiring an option on the commercial-while-held position. Opting and then disapplying under paragraph 6 adds administrative cost for no recovery uplift.
  • Property already covered by a substantial pre-option exempt grant history without automatic-permission cover. The prior-permission application under paragraph 28 may fail on the substantive fair-and-reasonable-attribution test, and the cost of preparing the VAT1614H may exceed the recovery prize.
  • Property held inside a VAT group with intra-group lets to substantially-exempt members. Group transparency means the intra-group let does not give rise to a supply at all; opting may be unnecessary, and may create unwanted VAT on third-party tenants of the same property.
