Indirect Disposals through Property-Rich Entities: Section 356OD and Section 517D

The classic developer planning question for any UK development project with significant latent value has long been the same: should the exit be a direct sale of the land or a sale of the shares in the SPV that holds the land. Pre-2016 the answer often pointed to the share sale, because the share-sale profit was a capital gain on a property-rich entity rather than trading profit on a land disposal. From 5 July 2016, section 356OD and section 517D close that route on the seller's side. The share-sale profit is recharacterised as trading profit where the disposal meets a distinct three-condition framework specific to indirect disposals.

This page works through that framework, the 50 percent UK-land derivation test, the tracing rules at section 356OM and section 517N, the priority over NRCGT for non-resident sellers, why the substantial shareholding exemption does not rescue the corporate seller, and the typical fact patterns that the regime catches. The general pillar on the transactions in UK land regime, covering the symmetric corporate/individual architecture and all four conditions for direct disposals, sits at transactions in UK land: the four-conditions test.

What section 356OD actually says

The corporate-side wording at CTA 2010 section 356OD applies to a disposal of property which, at the time of disposal, derives at least 50 percent of its value from UK land, where the disposing person is a party to or concerned in an arrangement concerning some or all of the land, and where the main purpose, or one of the main purposes, of the arrangement is to deal in or develop the project land and realise profit. Section 517D is the parallel for individuals.

Read carefully, the wording is structurally different from section 356OB's four-conditions test. Section 356OB asks four alternative main-purpose-or-trading-stock questions about the direct disposal of UK land. Section 356OD asks three cumulative questions about an indirect disposal: (i) is the property property-rich (50 percent derivation), (ii) is the disposer party to or concerned in an arrangement, (iii) is the arrangement's main purpose dealing-in or developing the land and realising profit. All three must be met for section 356OD to engage. Sessions writing on the regime sometimes describe section 356OD as "the four-conditions test applied to indirect disposals" but that framing is wrong: the test is its own three-condition framework, not a re-application of A to D.

The "arrangement" wording is intentionally broad. It covers contractual arrangements (a share purchase agreement structured around the developed value), joint-venture deeds, shareholders' agreements with profit-share waterfalls, and option arrangements that produce a profit-on-exit. The main-purpose evaluation at limb (iii) uses the same disjunctive "main purpose, or one of the main purposes" wording as Conditions A and D in the direct-disposal framework, with the same consequence: mixed purposes can coexist and one main purpose being profit-on-exit is enough.

The 50 percent derivation test

The threshold question for section 356OD is whether the property disposed of derives at least 50 percent of its value from UK land at the time of disposal. The test is fact-sensitive. For a single-tier SPV holding only UK development land, the answer is straightforward: 100 percent derivation from UK land. For a holding company holding shares in a property SPV plus a portfolio of unrelated commercial businesses, the answer depends on the relative value contributions at the disposal point.

The 50 percent test is read in line with the NRCGT property-rich threshold at TCGA 1992 Schedule 1A paragraph 8, which uses the same value-derivation framework for indirect disposals by non-residents. The two tests are not identical (NRCGT has additional participation thresholds at 25 percent; section 356OD has the arrangement-and-main-purpose limbs that NRCGT does not), but the 50 percent derivation point is shared. Sessions writing on property-rich SPVs need to keep the two frameworks separate while noting the shared derivation threshold.

Valuation at the disposal point is the operative question. Where a holding company has multiple subsidiaries, the relative value of the UK-land-derived subsidiary against the rest of the group at the share-sale date determines whether the 50 percent threshold is met. Cash on the holding company balance sheet, loan receivables from group companies, and non-UK-property subsidiaries all dilute the UK-land derivation but do not eliminate it. Where a structure has been deliberately diluted to fall below 50 percent (cash injections shortly before sale, asset transfers out to associated companies), the wider anti-avoidance rule at CTA 2010 section 356OK can still engage; section 356OD is not the only operative section.

Tracing rules: section 356OM and section 517N

The tracing rules at CTA 2010 section 356OM (companies) and ITA 2007 section 517N (individuals) walk the 50 percent derivation test through multi-tier corporate or partnership structures. Note the section numbering offset: s.356OM pairs with s.517N, not with s.517M (which is the individuals-only Private Residence carve-out at section 517M, with no corporate analogue). The tracing pairs are M-with-N, not M-with-M.

The tracing mechanic is straightforward in principle. Where a person disposes of shares in HoldCo, and HoldCo holds shares in PropCo, and PropCo holds UK land, the disposal is treated as deriving its value from UK land through the chain. The 50 percent test is applied at the level of the disposed-of property (HoldCo shares) using the value contributions traced down through the chain. Intermediate value contributions that are not UK-land-derived (cash, non-UK property, trading-business value at HoldCo or PropCo) dilute the derivation but do not break the trace.

The practical consequence: holding the UK development land two or three levels deep in a corporate structure does not avoid section 356OD. A non-resident developer using a Cayman parent over a Channel Islands intermediate over a UK PropCo is within scope on the same 50 percent test as a single-tier UK SPV. The pre-FA-2016 planning route of stacking holding companies to dilute UK-land derivation was largely closed by the tracing rules.

NRCGT priority and the non-resident-seller analysis

The most operationally significant interaction in this area is between section 356OD and the NRCGT regime at TCGA 1992 section 1A and Schedule 1A. Pre-FA-2019, non-resident disposals of UK residential property were within NRCGT but non-resident disposals of UK commercial property and indirect disposals of UK-land-rich entities were generally outside the UK CGT scope. The April 2019 NRCGT expansion brought non-resident indirect disposals into chargeable-gain scope for the first time, using a different framework from section 356OD (25 percent participation threshold, qualifying-investor exemption, 25 percent rate broadly aligned with UK residential CGT).

Where a non-resident disposal would otherwise be within NRCGT under Schedule 1A but the same disposal is caught by section 356OD or section 517D, the Part 8ZB or Part 9A trading-profit treatment takes priority. The chargeable-gain framework does not apply because the profit has been recharacterised as trading income. NRCGT operates as the capital-gain backstop for non-resident disposals that are not trading: where the section 356OD main-purpose test is not met (genuine investment-holding structure, no developer-side arrangement), the chargeable-gain treatment under NRCGT applies instead.

The deep-dive on the non-resident scope and the offshore-developer planning closure sits at non-resident developer UK tax scope. The structural point for sessions writing on multi-jurisdictional exits is that the priority rule is automatic, not elective; the seller does not pick whether to be taxed under NRCGT or Part 8ZB.

Why the substantial shareholding exemption is not a defence

The substantial shareholding exemption at TCGA 1992 Schedule 7AC exempts chargeable gains on certain disposals of substantial shareholdings in trading companies. The exemption is structurally important in M&A for trading-business sellers; SSE is what makes a clean share-sale exit feasible at the corporate-seller level. Pre-2016, SSE was sometimes positioned as a defensive layer for property-rich SPV sales where the underlying property activity could be characterised as trading.

Section 356OD removes that defence. The exemption operates on chargeable gains; section 356OD recharacterises the share-sale profit as trading income, which is not a chargeable gain. SSE has no application to trading-profit recharacterisation. A corporate seller of an SPV whose disposal meets the section 356OD three-condition framework cannot rely on SSE; the profit is trading income at the prevailing corporation tax rate.

The reverse interaction also holds: a developer SPV whose underlying activity does not meet section 356OD (genuine investment-letting business, no main-purpose arrangement) may still be able to use SSE on a share-sale exit if the SPV's underlying business meets the SSE trading-company test. The two frameworks operate in different territories: SSE on chargeable gains for trading-company shares, section 356OD on trading-profit recharacterisation for indirect disposals of property-rich entities.

Typical fact patterns and the structural traps

Three recurring fact patterns are caught cleanly by section 356OD:

• Developer SPV with planning consent and partial works. A developer obtains a development site, sets up a single-purpose SPV, takes the project to planning consent and partial-works execution, and sells the SPV shares to a successor developer at the developed value. The arrangement is a share-purchase agreement with consideration tied to the development value. The main-purpose evaluation engages cleanly: the arrangement's purpose is to deal in or develop the land and realise profit on disposal of the SPV shares.
• Forward-funded development structure. A funder takes shares in a developer SPV with a profit-share waterfall tied to the development outcome. On completion and sale, the funder's share-sale exit is part of an arrangement to deal in or develop the land and realise profit. The funder is within scope of section 356OD even though the funder did not directly execute the development.
• Multi-tier offshore holding with UK land. A non-resident developer holds UK development land through a corporate chain (offshore parent, intermediate holding, UK PropCo). The exit is a share sale at the offshore parent level. The tracing rules at section 356OM walk the 50 percent test through the chain; the arrangement-and-main-purpose limbs of section 356OD engage at the parent share-sale level. The corporate structure does not insulate from Part 8ZB.

Cases that fall outside section 356OD include genuine investment-holding share sales (where the SPV's underlying business is letting rather than development), pre-planning-consent share sales (where the disposal value reflects the land alone rather than developer profit), and minority interests sold below the participation thresholds that limb (ii) implies (the "concerned in an arrangement" wording reaches further than direct contractual participation, but not every minority shareholder in a property-rich entity is a party to an arrangement under section 356OD).

How section 356OD interacts with the other limbs of Part 8ZB

Section 356OD is structurally separate from the four-conditions test in section 356OB. Section 356OB applies to direct land disposals; section 356OD applies to indirect disposals of property-rich entities. The two sections operate in different territories. A developer disposing of UK land directly is tested under section 356OB; a developer disposing of shares in an SPV holding UK land is tested under section 356OD.

Three interactions matter on operational structures:

• The anti-fragmentation rule at section 356OH can engage alongside section 356OD where the structure separates the development entity, the land-holding SPV, and the eventual share-sale entity. Activities of connected entities are attributed for the main-purpose evaluation. The deep-dive sits at anti-fragmentation under section 356OH.
• The wider anti-avoidance rule at section 356OK can engage where structures are designed specifically to fall outside the section 356OD framework (cash dilution shortly before sale, asset transfers out of the property-rich entity, contractual obfuscation of the underlying main purpose). Section 356OK reaches further than section 356OD on facts where the latter is technically not met.
• Section 356OB Condition C (trading stock) and section 356OD can coexist where the underlying land is in trading-stock accounts at the SPV level. Sale of the SPV's land triggers Condition C directly; sale of the SPV's shares triggers section 356OD on the indirect disposal. The trading-stock classification supports the main-purpose evaluation under section 356OD's three-condition framework.

The buyer-side analysis on an SPV share purchase

Section 356OD operates on the seller's profit on disposal. The buyer's position on an SPV share purchase is structurally different. The buyer is acquiring shares in a company; SDLT on the underlying land does not arise at the share-purchase level (subject to Schedule 7 group-relief considerations and the SDLT anti-avoidance rules); the buyer's tax basis in the SPV is the share-purchase price; the SPV's tax basis in the land is unchanged by the share-sale transaction.

Three buyer-side implications matter operationally. First, the SPV inherits the seller's trading-stock or investment classification at the land level. A buyer acquiring an SPV holding trading-stock land is buying a developer business; the eventual unit sales by the SPV produce trading profit at the prevailing corporate rate. A buyer acquiring an SPV holding investment property is buying a letting business; future disposals produce chargeable gains. The classification is not flexible at the share-purchase point.

Second, the buyer's representations and warranties package in the share-purchase agreement typically addresses the seller's section 356OD position. A buyer-side reps-and-warranties claim against an inadequate disclosure of the seller's main-purpose record is a real risk where the seller treated the disposal as a chargeable gain and HMRC subsequently recharacterises under section 356OD. The financial cost of recharacterisation sits with the seller, but the deal-side disruption (covenants, escrows, completion accounts) can reach the buyer.

Third, the buyer's own future exit needs to be modelled. An SPV acquired in 2026 may be sold again in 2030; section 356OD applies to the eventual share-sale disposal in the same way as it applied to the original. The corporate basis of the SPV does not reset on each share-sale transaction; the underlying land carries its tax history through successive ownership.

The Schedule 1A NRCGT framework alongside section 356OD

For sessions writing on non-resident sellers, the interaction between TCGA 1992 Schedule 1A (NRCGT on indirect disposals of UK-land-rich entities) and section 356OD warrants a separate paragraph because the two frameworks address the same operational fact pattern from different sides. Schedule 1A applies a chargeable-gain treatment with a 25 percent participation threshold (the disposer or connected persons must hold at least 25 percent of the entity at some point in the two years before disposal). Section 356OD applies a trading-profit treatment with the three-condition framework and no participation threshold (though the arrangement-and-main-purpose limbs effectively require some level of involvement).

The two frameworks produce different operational outcomes on the same fact pattern. A minority non-resident shareholder in a property-rich SPV (below 25 percent participation) is outside Schedule 1A entirely and the chargeable-gain treatment does not engage. The same minority shareholder may be within section 356OD if "concerned in an arrangement" reaches the minority position, with trading-profit treatment applying instead. Conversely, a 100 percent non-resident owner of an investment-letting SPV is within Schedule 1A on chargeable-gain treatment but outside section 356OD because the underlying business is not developer activity. Sessions advising non-resident structures need to run both frameworks at the planning stage; the operative one depends on the facts.

Practical takeaways for SPV-structured developers

For developer-side structures with planned share-sale exits, the operational implications of section 356OD are:

• The share-sale route does not avoid trading-profit treatment where the underlying activity meets the main-purpose test. Structuring the exit through an SPV is a commercial and SDLT-side choice, not a tax-rate choice on the seller's profit.
• Multi-tier holding structures (HoldCo over PropCo over UK land) are within scope through the tracing rules. Offshore parents do not insulate from Part 8ZB.
• SSE planning at the corporate-seller level is not a defence; section 356OD operates on trading profit, not on chargeable gains.
• The arrangement-and-main-purpose wording is fact-sensitive; structures where the underlying business is genuine investment-letting (not development) and the share-sale arrangement does not have a profit-on-exit main purpose may fall outside section 356OD. The documentary record at the arrangement point is what supports or undermines the position.
• For non-resident sellers, the priority rule with NRCGT means there is no elective treatment; if section 356OD engages, Part 8ZB applies and NRCGT is the backstop only where the trading-profit test is not met.

The existing NRCGT-side coverage on this site sits at NRCGT indirect disposals of property-rich companies. That page covers the chargeable-gain framework under TCGA 1992 Schedule 1A; this page covers the trading-profit framework under section 356OD. Both should be read together for non-resident-seller analyses.
