Property decoupling commonly refers to one co-owner transferring or selling their share of a property to the other co-owner. After the transaction, one person becomes the sole owner of the property while the outgoing owner no longer has an ownership interest.
For stamp-duty purposes, a transfer or purchase of an interest in a property can be treated as a property acquisition or disposal, so BSD, ABSD and SSD may apply depending on the circumstances.
For example: If a couple each owns 50% of a private property, one owner may sell their 50% share to the other. The remaining owner will then own 100% of the property.
The transaction may involve payment for the transferred share, repayment or restructuring of the existing home loan, CPF refunds, stamp duties and legal documentation. The exact structure will depend on the owners’ financial situation and the existing property loan.
Common costs may include:
BSD is generally calculated on the higher of the purchase price or market value of the property interest being transferred.
Your actual costs will depend on the property value, ownership share, citizenship, number of properties owned, CPF usage and financing arrangement.
It depends on your citizenship and the number of residential properties you own.
Importantly, if you are a Singapore Citizen who owns only one residential property and you are buying the remaining share of that same property from your co-owner, IRAS states that no ABSD is payable on the acquisition, although BSD remains payable.
The treatment can be different if you already own other residential properties or if you are a Singapore Permanent Resident or foreigner. For example, IRAS provides specific partial ABSD remission rules in certain cases where an owner acquires an additional share in a property they already partly own.
Because ABSD can be substantial, the applicable treatment should be confirmed before proceeding.
Not necessarily. The financing arrangement depends on the existing mortgage, outstanding loan amount and how the part-purchase is structured.
If the remaining owner needs additional or new financing, the bank will assess the application based on its lending criteria and applicable MAS requirements. For property loans subject to TDSR, the current TDSR limit is generally 55% of the borrower’s monthly income.
Depending on the situation, the existing loan may need to be refinanced or restructured. The available options will depend on the bank and the borrower’s eligibility.
Yes, you may be able to use your CPF Ordinary Account (OA) savings to fund the part-purchase, subject to CPF housing rules and the amount of CPF you are eligible to use.
CPF OA savings can generally be used for a residential property purchase, including the downpayment, housing loan payments and certain stamp duty and legal fees. However, the amount you can use depends on factors such as the property value, remaining lease, your age, existing CPF usage and the type of housing loan.
For example, if you are buying your co-owner’s 50% share of a private property, your available CPF OA savings may be used towards the amount you need to pay for that share, subject to the applicable CPF withdrawal limits.
It is also important to account for the outgoing owner’s CPF. If they previously used CPF for the property, they will generally need to refund the CPF principal used plus accrued interest when their share is transferred or sold.
In simple terms: CPF can help reduce the amount of cash you need for the part-purchase, but the amount available will be different for every case.
HDB flats do not follow the same decoupling process as private properties.
HDB does allow certain changes in flat ownership, including a resale of part-share, where one existing owner sells their share to another eligible owner. However, the transaction must meet HDB’s eligibility conditions and receive HDB approval.
This means HDB owners generally cannot simply remove one spouse or co-owner from the flat in the same way private-property owners may structure a decoupling. Factors such as the family nucleus, citizenship, Minimum Occupation Period (MOP), existing ownership and HDB eligibility requirements may affect whether the ownership change can proceed. HDB also requires core members to remain in the flat application and physically occupy the flat during the applicable MOP.
For this reason, if your intention is to change ownership of an HDB flat, you should first check whether you qualify for HDB’s Change in Flat Ownership or Resale of Part-Share process.
