ABSD Remission Timelines for Large and Mega En Bloc Redevelopments

The Ministry of Finance and Ministry of National Development revised the Additional Buyer’s Stamp Duty for housing developers (ABSD(HD)) remission timeline framework for qualifying large-scale en bloc redevelopments. The revised categories apply to qualifying en bloc sites purchased on or after 29 July 2026. This is a developer tax-remission framework, distinct from the owner-consent rules for a collective sale and from the ordinary ABSD rates paid by residential buyers (MOF/MND, 28 July 2026).

Revised large and mega site categories

Licensed housing developers remain subject to 40% ABSD when purchasing residential land: 5% is non-remittable and 35% is an upfront remittable component whose remission can be clawed back if the applicable development, completion and sale timelines are not met. For qualifying Category 1 en bloc sites purchased from 29 July 2026, the revised framework distinguishes a Large Site (Category 1A) yielding 700–1,399 residential units and a Mega Site (Category 1B) yielding at least 1,400 units. Both require a redevelopment yield at least 1.5 times the existing number of residential units.

For both categories, the commencement timeline remains 2.5 years. The completion-and-sale timeline becomes 6 years for a Large Site and 7 years for a Mega Site, compared with 5.5 years previously for the earlier large-site category. A Mega Site must sell at least 50% of its residential units by the end of 6 years; failing that can trigger full clawback of the 35% upfront remittable component with interest (MOF/MND, 28 July 2026).

Additional extensions and scope

If a Large or Mega Site also falls within more than one qualifying complex-project category, it receives an additional six-month extension. The resulting timelines are 3 years to commence and 6.5 years for completion and sale for a Large Site, or 7.5 years for a Mega Site. Regular en bloc sites yielding 5–699 units retain the 2-year commencement and 5-year completion-and-sale timelines, subject to the applicable framework. The revised timelines are therefore conditional remission requirements for licensed developers, not a general extension for every private housing project or every collective sale.

The framework is intended to support redevelopment that rejuvenates older estates and adds housing supply while retaining incentives for prudent land acquisition and timely delivery. It is not a general change to buyer ABSD: the revision concerns conditional remission for licensed developers acquiring qualifying redevelopment sites. A developer that meets the intermediate 50% sales condition for a Mega Site must still sell all units and complete the development by the end of the applicable final timeline to avoid the relevant clawback (MOF/MND, 28 July 2026).
