- From 29 July 2026, developers of large collective sale sites get longer to build and sell before ABSD becomes payable: six years for 700 to 1,399 units, seven years for 1,400 or more.
- Smaller sites are unchanged at two years to start work and five years to sell out.
- The two larger tiers must also intensify the site by at least 1.5 times, and the largest tier must sell half its units by year six.
- This is a developer-side change. Buyer-side ABSD rates were not touched by this package.
- Two large collective sales that failed — Pine Grove and Braddell View — are the kind of site this is aimed at.
How the ABSD deadline works
When a licensed housing developer buys residential land, ABSD is charged on the purchase. The developer can have most of it remitted, but only by meeting a deadline: finish the project and sell every unit within a set number of years.
Miss the deadline and the remitted ABSD becomes payable, with interest, on the whole land price. On a large site that is a very big number, and it lands whether the developer sold ninety per cent of the units or nine.
So the deadline is not an administrative detail. It is the single biggest risk a developer prices in when bidding for a collective sale site — and the bigger the site, the harder that risk is to carry.
What changed on 29 July
The deadline is now tiered by the size of the completed redevelopment.
| Units after redevelopment | Start work within | Complete and sell out within | Other conditions |
|---|---|---|---|
| 5 – 699 | 2 years | 5 years | None |
| 700 – 1,399 | 2.5 years | 6 years | Intensify the site at least 1.5× |
| 1,400 or more | 2.5 years | 7 years | Intensify at least 1.5×, and sell 50% of units by year 6 |
A site that qualifies under more than one complexity category gets a further six months on top — so six and a half years for the middle tier, seven and a half for the largest.
Read the conditions together and the intent is clear. The extra time is not a general loosening. It is offered to developers who take on a big site and build significantly more homes on it than were there before.
Why this needed fixing
Very large collective sales had stopped working.
A site of well over a thousand units cannot realistically be demolished, redeveloped and fully sold in five years. Demolition alone takes time. Then there is the construction programme, and then a sales run long enough to absorb more than a thousand units without dumping them on the market at a discount.
Faced with that, developers either bid low enough to cover the ABSD risk — which owners then reject as below their reserve price — or they do not bid at all.
Pine Grove and Braddell View are the two names PropNex points to. Both are large sites. Both went to the market. Neither sold.
The new tiers change that arithmetic. A seven-year runway on a 1,400-unit project is a materially different risk from a five-year one, and it should show up in what developers are willing to bid.
What it means if you own in a large estate
If you own a unit in a big, ageing development that has talked about a collective sale, this is the most relevant thing in the July package for you.
It does not make an en bloc happen. It removes one specific reason large sites were not attracting bids. Everything else is exactly as it was: you still need the consent threshold, you still need a reserve price the market will meet, and you still need the redevelopment maths to work for a buyer.
What it may change is the level of interest, and therefore the price. Owners in very large estates who have watched two rounds fail now have a better case for going again.
One practical note. A longer sales runway for the developer also means a longer wait before the new project completes. If you are planning your own next move around en-bloc proceeds, the timeline you should plan against just got longer at the far end, not shorter.
What this does not change
This is a developer measure. It does not change the ABSD you pay as an individual buying a second or third property, and it does not change the remission route married couples use when they buy before selling.
Those rates and rules sit with IRAS and were not part of this announcement. If you are working out your own ABSD position on a purchase, that is a separate calculation, and we are happy to run it with you.
What we are watching next
Two things.
First, whether large sites come back to market, and at what reserve. The test is not whether owners launch — it is whether developers bid, and whether the bids clear.
Second, the effect on new launch supply from about 2029 onward. If several very large sites transact over the next eighteen months, that is a meaningful volume of units arriving at roughly the same time, and it belongs in any long-range plan for a resale exit.
Questions we are being asked
Does this change the ABSD I pay as a buyer?
No. This revision applies to the remission conditions for licensed housing developers buying residential land for redevelopment. Buyer-side ABSD rates for individuals were not changed by the 29 July package. Confirm your own position with IRAS or your conveyancing lawyer before you commit.
How long does a developer now have to sell out?
Five years for a completed project of 5 to 699 units, six years for 700 to 1,399 units, and seven years for 1,400 or more. Sites qualifying under more than one complexity category get a further six months. Work must begin within two years for the smallest tier and two and a half for the larger two.
What does "intensify at least 1.5 times" mean?
The completed redevelopment has to deliver at least one and a half times what the site had before. The extended deadlines are reserved for projects that add housing supply, not for like-for-like rebuilds.
Does this make a collective sale more likely for my estate?
It improves the odds specifically for very large ageing sites, where the five-year deadline made the risk hard to price. It does not change your consent threshold, your reserve price, or whether the redevelopment maths works. If your estate is under a few hundred units, nothing here applies to you.
What happens if the developer still misses the deadline?
The remitted ABSD becomes payable with interest. The extension changes the deadline, not the consequence of missing it.
