A strategy where one co-owner of a property buys out the other's share so that one owner no longer counts as a property owner, usually to free that person to buy another property as a 'first' purchase and reduce Additional Buyer's Stamp Duty. In Singapore this works only for privately-owned property — HDB flats generally cannot be decoupled simply to buy a second home.
Example: Two co-owners of a private condo might decouple so one fully owns it and the other can buy a second property at lower ABSD. But the buy-out itself triggers Buyer's Stamp Duty on the transferred share (and possibly Seller's Stamp Duty if within the holding period), so the ABSD saving must be weighed against these costs. Confirm all rates with IRAS.
Decoupling is when one co-owner transfers their share of a property to the other co-owner, leaving a single owner. The exiting party no longer owns that home, so they can buy another property as a first-timer and avoid the Additional Buyer's Stamp Duty that a second purchase would otherwise attract.
No. Since 2016 HDB has barred decoupling of HDB flats — co-owners can no longer transfer a share to one another purely to free up the other for a second purchase. Ownership changes are generally allowed only in limited situations such as divorce or by court order. Decoupling now applies in practice to private property.
The transferred share still attracts Buyer's Stamp Duty, and you pay legal fees for two conveyancing firms — often around S$5,000 to S$6,000 in total — plus any valuation and refinancing costs. The sums only make sense if the ABSD saved on the next purchase clearly exceeds these costs.
Genuine decoupling of private property is legal, but IRAS scrutinises arrangements engineered mainly to dodge ABSD. Contrived 99-to-1 structures set up at purchase to enable later tax avoidance have been challenged and back-taxed with penalties, so the transaction must have real commercial substance.
