The Singapore Government has revised the Additional Buyer’s Stamp Duty regime for licensed housing developers undertaking large-scale residential en bloc redevelopment projects.
The changes are intended to give developers more time to complete and sell units in very large developments, while encouraging the rejuvenation of older estates and the addition of new housing supply.
The revised timelines apply to qualifying en bloc sites purchased on or after 29 July 2026.
Key Highlights
- Large en bloc sites are defined as developments yielding between 700 and 1,399 residential units.
- Large sites may receive six years to complete the development and sell all units.
- Mega en bloc sites are developments yielding at least 1,400 residential units.
- Mega sites may receive seven years to complete the development and sell all units.
- Mega-site developers must sell at least 50% of the units by the end of the sixth year.
- The redevelopment must generally produce at least 1.5 times the number of units in the existing development.
How Developer ABSD Works
Licensed housing developers purchasing residential land are generally subject to Additional Buyer’s Stamp Duty of 40%.
This comprises:
- A 5% component that is non-remittable; and
- A 35% component that may be remitted upfront, subject to development and sales conditions.
Under the general framework, a developer must commence the housing development within two years and complete the project and sell all residential units within five years from the acquisition date.
If the applicable conditions are not met, the remitted ABSD may be clawed back together with interest.
Revised Timelines for En Bloc Redevelopments
| Site Category | Units After Redevelopment | Commencement | Completion and Sale | Intermediate Condition |
|---|---|---|---|---|
| Regular En Bloc Site | 5–699 units | 2 years | 5 years | None |
| Large En Bloc Site | 700–1,399 units | 2.5 years | 6 years | None |
| Mega En Bloc Site | At least 1,400 units | 2.5 years | 7 years | At least 50% sold by the end of year 6 |
Large En Bloc Sites
A qualifying large en bloc site is one that can yield at least 700 but fewer than 1,400 residential units after redevelopment.
For these projects, the completion and sale timelines will be extended from the previous 5.5 years to six years.
The commencement timeline remains at 2.5 years. The redeveloped project must also generally yield at least 1.5 times the number of residential units in the original development.
Mega En Bloc Sites
A mega en bloc site is one that can produce at least 1,400 residential units after redevelopment.
These developments will receive up to seven years to complete the project and sell all residential units, compared with the previous timeline of 5.5 years.
However, an intermediate sales condition will apply. Developers must sell at least 50% of the residential units by the end of the sixth year.
Important Condition for Mega Sites
If fewer than 50% of the units are sold by the end of year six, the developer will face a full clawback of the 35% remittable ABSD component, together with interest. Even after meeting the 50% condition, the developer must still complete the project and sell all units by the end of year seven.
Further Extensions for Complex Projects
A large or mega en bloc project that also qualifies under another category of the ABSD remission timeline extension framework may receive an additional six-month extension.
This may apply to projects involving complex technical or infrastructure requirements, the Strategic Development Incentive scheme, or qualifying construction technologies and productivity measures.
Where the additional extension applies:
- The commencement timeline may be extended to three years;
- Large sites may receive 6.5 years for completion and sale; and
- Mega sites may receive 7.5 years for completion and sale.
Mega developments must still satisfy the requirement to sell at least 50% of their units by the end of the sixth year.
Why the Government Is Revising the Framework
Very large en bloc redevelopments are often more complicated than conventional residential developments. Developers may need more time to demolish existing buildings, plan the redevelopment, manage infrastructure requirements and construct a significantly larger number of homes.
The revised framework seeks to make large collective-sale sites more viable for developers while preserving the Government’s objective of ensuring that new housing supply is released in a timely manner.
The changes may also encourage the redevelopment and rejuvenation of ageing private residential estates that could otherwise be difficult to sell collectively because of their size.
Possible Impact on the En Bloc Market
The longer timelines could improve developer interest in very large collective-sale sites, as developers will have more time to build and sell a substantial number of units.
However, developers will still have to assess construction costs, financing expenses, market demand, sale prices, planning restrictions and the substantial acquisition cost of a large en bloc site.
The revisions do not guarantee that every large estate will successfully complete an en bloc sale. Reserve prices and redevelopment potential must still be commercially viable.
What En Bloc Owners Should Consider
- Estimate the potential number of units that can be built after redevelopment.
- Confirm whether the site meets the minimum 1.5-times intensification requirement.
- Review the development baseline, plot ratio and planning controls.
- Assess whether the reserve price remains attractive to developers.
- Consider construction, financing and ABSD-related risks faced by potential buyers.
- Obtain professional valuation, planning, legal and collective-sale advice.
TopBroker’s View
The revised timelines address a practical challenge faced by developers considering exceptionally large collective-sale sites. Allowing six or seven years for qualifying projects could improve their commercial feasibility, but acquisition price, financing, planning potential and expected demand will remain decisive. Owners should therefore avoid assuming that the extended timelines alone will make an ambitious reserve price acceptable to the market.
