Decoupling is a property strategy used by married couples in Singapore to structure their property ownership in a way that allows one spouse to acquire a second property without triggering Additional Buyer's Stamp Duty (ABSD). It has been a popular planning tool, though its use requires careful consideration of both financial and personal implications.
How Decoupling Works
When a couple jointly owns a property, both names are on the title — meaning each individual is counted as owning a property. If they want to purchase a second property, ABSD applies at the rate for a second property (currently 20% for Singapore Citizens).
Decoupling involves one spouse transferring their share of the existing property to the other, leaving the first spouse as sole owner of the original property. The transferring spouse then has no property in their name — and can purchase a second property as a "first-time buyer," with no ABSD. The couple effectively holds one property each, structured to avoid the second-property ABSD on the new acquisition.
The Costs of Decoupling
The transfer of one spouse's share is not cost-free. Buyer's Stamp Duty applies on the value of the share transferred, calculated on the current market value of the property. Legal fees apply. And a new bank loan arrangement may be needed. These costs need to be weighed against the ABSD savings from the second purchase. At current BSD rates and for most property values, the savings from avoiding ABSD on the new purchase typically justify the decoupling costs — but the calculation should be done explicitly.
The Risks
The primary risk of decoupling is that it involves one spouse owning the original property solely. If the relationship changes — through divorce or other circumstances — the sole owner holds 100% of the asset. The couple should ensure their financial and legal arrangements around ownership are documented and understood before proceeding. This is a conversation that should happen with a lawyer, not just a property agent.
