Section 13W Share Disposal Gains: 2026 Rules, Group Holdings and Property Exclusions

Edition and the 2026 change

This article follows the twenty-seven-page fourth edition of 30 September 2025. Earlier editions were published on 30 May 2012, 15 July 2016 and 10 December 2020. Section 13W provides upfront certainty for qualifying equity-disposal gains, supporting restructuring and reducing compliance uncertainty. The original scheme began on 1 June 2012. Budget 2025 removed the 31 December 2027 sunset and introduced eligible preference shares and company-group assessment for disposals from 1 January 2026.

Ordinary tax treatment remains the starting point

The guide says capital gains are not taxed, while revenue gains and losses can be taxable or deductible. Character is assessed using the facts and badges of trade: acquisition motive, holding period, similar transaction frequency, disposal reasons and acquisition finance. Section 13W gives certainty when its conditions are met; failure to qualify does not automatically turn a capital gain into taxable income. Other applicable regimes and awarded incentive rules must still be considered.

Which shares and investees are within scope

Before 1 January 2026, the scheme covers ordinary-share disposals from 1 June 2012 through 31 December 2025. From 1 January 2026, it also covers preference shares accounted for as equity by the investee under its applicable accounting principles. If the investee is not required to follow accounting principles, use IFRS for this classification. A marketing label or the seller’s classification alone does not establish qualifying equity. Investees may be Singapore or foreign, listed on SGX or another exchange, or unlisted, subject to the property exclusions.

Before 2026: continuous entity-level 20%

Immediately before disposal, the seller must have maintained at least 20% ordinary-share ownership on every day of the preceding twenty-four months. Before 2026, this is an entity test, not group aggregation. Annex A1 illustrates why an earlier qualifying sale can reduce the holding and prevent a later sale from meeting the test.

From 2026: the capital measure and two routes

The 20% threshold refers to the total paid-up share capital of ordinary and qualifying preference shares. The seller must hold at least 20% continuously for the twenty-four months immediately preceding disposal. First assess its own holding. If that fails, qualifying companies may use a group basis. Registered business trusts and VCCs can use the scheme on their own holdings, but cannot use group assessment. Do not confuse this capital-value threshold with the separate group-membership test based on numbers of ordinary shares.

Group membership: more than 50% beneficial ownership

Companies are in the relevant group when one, including the seller, beneficially owns directly or indirectly more than 50% of the total issued ordinary shares of the other, or a common company beneficially owns more than 50% in each. Indirect percentages require multiplication through the chain. A non-company intermediary, such as an LLP, breaks the company relationship illustrated in the guide. Exactly 50% does not meet a more-than-50% condition.

Five steps for the group route and FIFO

Identify the disposal date; establish the preceding twenty-four months; identify eligible group members; aggregate only investee shares each member held continuously throughout that entire period; and then determine which disposed shares were also continuously held for that period. Apply first-in-first-out to disposals for the aggregation and qualifying-disposal tests. A group percentage at or above 20% on each date is not sufficient when different newly acquired parcels replace the old continuously held shares. Under this route, a recently acquired disposed parcel does not qualify merely because older group shares satisfy the threshold.

Excluded sellers and property rules before June 2022

A seller whose disposal gains form section 26 income is excluded. For disposals before 1 June 2022, the scheme excludes unlisted shares in investees trading Singapore immovable property or principally holding Singapore property for passive or no income. Property development was not then excluded on that basis, and the section 10D property-letting business remained within scope. This historical rule differs from the wider property exclusions that follow.

Property exclusions from 1 June 2022

For unlisted investees, the exclusions extend to property in Singapore or abroad: trading immovable property; principally holding it for passive or no income; or having undertaken property-development activity. The development exception requires both use of the developed property in the investee’s own business to derive trade income and no development activity in the sixty months before the share disposal. A genuine property-letting business may derive section 10D trade income; entirely passive rental is different. Property held as trading stock does not count as own-business use.

Development, structural work and the sixty-month clock

Development includes constructing or causing construction of all or part of a building, including acquiring land or a building for that construction. Only structural additions or alterations requiring Building Control approval count. Overseas works are judged by whether equivalent works would need that approval in Singapore. The activity is completed on issuance of the Certificate of Statutory Completion, or CSC, not merely by the passage of time or a change in use. Consider all development undertaken; the guide explains disposals more than sixty months after all relevant CSCs meet the no-recent-development condition.

Losses, incentives and claiming the scheme

A loss in otherwise qualifying circumstances is not automatically disregarded: ordinary capital-versus-revenue rules apply. Gains that fail the threshold, fall within exclusions or arise on pre-2026 non-ordinary shares are not automatically taxed. Where an awarded tax incentive governs such gains or losses, its rules also apply.

The company chooses whether to claim. Provide the required information in the return for the YA whose basis period includes the disposal, and retain sufficient holding, equity-classification and exclusion evidence. Documents need not accompany the return, but must be supplied on request. Without the required claim information, IRAS applies the ordinary character analysis.

Seven FAQs and the S$500,000/S$200,000 example

The FAQs confirm the choice to claim, access for companies already enjoying incentives, entity-only access for registered business trusts, and access regardless of seller tax residence. Converted bonds start the ordinary-share holding clock on conversion; the bond holding period is not added. Under an elected section 34C amalgamation, the successor steps into the predecessor’s position and inherits the original acquisition date.

Where one qualifying disposal gains S$500,000 and another loses S$200,000, the financial statements’ S$300,000 net result does not decide tax. The qualifying S$500,000 gain is not taxable, while the S$200,000 loss requires its own ordinary character assessment. Do not exempt or disallow the net amount automatically.

Annex A1: the first sale qualifies but the second does not

A company acquires 40% on 1 March 2010, sells 30% on 1 September 2012 and the remaining 10% on 1 August 2013. Before the first disposal it maintained at least 20% for thirty months, so the first gain qualifies. The later twenty-four-month period, 1 August 2011–31 July 2013, includes ownership below 20% after the first sale. The second gain fails the certainty condition and returns to ordinary analysis. A long original investment history does not cure the later reduction.

Annex A2-1: all six group-membership examples

Example 1: A owns 100% of B; both hold 10% in the investee, so A and B are group members. Example 2: A owns 80% of B and B owns 70% of C, giving A 56% of C; A and C are members. Example 3: A owns 60% of B LLP, which owns C; the LLP intermediary prevents the company-group test.

Example 4: common A owns 80% of B, 70% of foreign C and 60% of D; all three are members, holding 5%, 10% and 5% in the investee. Example 5: A owns 80% of foreign B, B owns 70% of D; A also owns 80% of C, C owns 60% of foreign E. D is indirectly held at 56%, but E at 48%, so D and E are not in the same qualifying group. Example 6 replaces E’s intermediary with an LLP, again preventing group membership even though the diagram shows 60% and 100% links.

Annex A2-2, example 1: only the old 10% qualifies

B and C share a qualifying parent. On 1 January 2025 each holds 10%, producing 20% group ownership. B adds 5% on 31 December 2025 and sells all 15% on 1 January 2027. The relevant period is 1 January 2025–31 December 2026. The original 10% held by each throughout that period meets the 20% group threshold. FIFO identifies B’s sold parcels as the old 10% and newer 5%. Only gains on the old 10% qualify through the group route; the newer 5% did not span the full period.

Example 2: the complete holding timeline

On 1 January 2025 B holds 15% and C 10%; on 31 December 2025 B adds 5%, making 20%/10%. On 1 January 2026 C sells 5%, leaving 20%/5%. On 31 December 2026 B adds 5%, making 25%/5%; on 1 January 2027 C adds 5%, making 25%/10%. On 31 December 2027 B sells 25% and C sells 5%, leaving 0%/5%. Each disposal requires a separate test, not just the final 30% sale total.

Example 2: the three disposal outcomes

B’s 25% sale on 31 December 2027 qualifies entirely on its own entity basis, because B held at least 20% throughout 31 December 2025–30 December 2027. This includes the extra 5% acquired on 31 December 2026: the stricter disposed-parcel rule described for the group route is not imposed on this qualifying entity-level sale.

C’s 5% sale on 1 January 2026 fails because neither member had shares throughout 1 January 2024–31 December 2025. C’s later 5% sale on 31 December 2027 qualifies through group aggregation: B’s old 20% plus C’s surviving old 5% were held throughout 31 December 2025–30 December 2027, and FIFO identifies C’s sold 5% as the old parcel acquired on 1 January 2025.

Example 3: a constant headline 20% is insufficient

On 1 January 2025 B and C hold 10% each. On 31 December 2025 B sells its 10% while C adds 10%, leaving 0%/20%. On 1 January 2026 B acquires 5% while C sells 5%, leaving 5%/15%; on 1 January 2027 each sells 5%, leaving 0%/10%. Across 1 January 2025–31 December 2026, FIFO leaves B with no original parcel and C with only 5% continuously held. Both 1 January 2027 sales therefore fail the group 20% condition. C’s 1 January 2026 sale also fails its earlier twenty-four-month test.

The printed example describes B’s 31 December 2025 sale using group steps even though group assessment only starts on 1 January 2026. That is a chronological inconsistency in the example, not permission to apply the new route early. B’s sale still fails: under the applicable pre-2026 entity rule, its holding never met 20% for twenty-four months. The example’s outcome is preserved while the differing legal route is identified.

Annexes B1 and B2: practical decision order

First exclude a section 26 seller and check whether an unlisted investee falls within the property exclusions for the disposal date. Then identify eligible share classes and whether the disposal produced a gain. Before 2026, test the seller’s continuous 20% ordinary-share holding. From 2026, test ordinary and qualifying preference capital on the entity basis, then, if needed and available, the five-step group route. A qualifying gain can use certainty; a loss or failed condition returns to normal tax rules, including an applicable incentive. This reproduces both flowcharts as a readable process.

Annex C: all five property-use examples

A owns 100% of X and sells on 1 January 2023. X completed its only development with CSC on 1 January 2017 and had no later development, satisfying the sixty-month condition. Case 1 uses the factory and office for manufacturing: qualifies. Case 2 uses part for manufacturing and lets two floors for passive rent: the example still qualifies because the property supports its manufacturing trade. Case 3 operates the developed hotel: qualifies. Case 4 conducts a section 10D commercial-property letting trade: qualifies. Case 5 develops residential units as stock for sale: excluded property trading.

If development is ongoing at disposal or occurred within the preceding sixty months, the development exception fails regardless of present or planned property use. Ordinary character analysis then determines whether the gain is taxable; failure of section 13W does not itself make it revenue income.
