The Article to Read Before You Decide to Decouple
Let’s be honest: you are here because you and your partner are looking to buy another property but you are trying as hard as you can to avoid having to fork out a sum of money for the dreaded Additional Buyer’s Stamp Duty—a tax that s levied on property buyers.
Judging by how “How can I avoid paying ABSD” is a commonly searched up question on Google, it is no wonder “decoupling” has been (and continues to be) a buzzword in the property world. While the term is often thrown around when it comes to property ownership, not many have a clear idea about what it is exactly, and what it entails.
This article covers everything you need to know about decoupling. You will learn about the who, what, where, when, and how of this buzzword. At the end of it, you can make a more informed decision on whether or not you should decouple!
What is decoupling?
To fully understand what decoupling means, let’s go back to the basics to look at the dictionary definition of the word. According to the dictionary, to decouple is to separate, disengage, or dissociate (something) from something else.
At its core, that is exactly what decoupling in the property market means—it is to divide the shared ownership of a property between a couple. Decoupling property is a legal exercise whereby you sell your share in the private property to your spouse.
Ownership of the title is then legally transferred and the property becomes solely owned. This also means that mortgage payments would become solely taken up by one instead of split between two. To accomplish this, couples have to sign and submit an instrument in the requisite forms prepared by lawyers to the Singapore Land Authority.
Here, it is important to note that there is a distinction to be made between decoupling for HDB flats and decoupling for private properties—for married couples, only private properties can be jointly owned and subsequently decoupled. Married couples are not allowed to decouple their HDB flat. Decoupling for a HDB flat is only allowed for buy over from an ex-spouse or for the transfer of the flat between family members.
Why, the double standard, you ask? Because the HDB ownership transfer rule was tightened in 2016 after it was found that many HDB homeowners were abusing it. Subsequently, only transfers under six special cases: marriage, divorce, death of an owner, financial complications, renunciation of citizenship and medical reasons were allowed.
Why do people want to decouple?
As mentioned earlier, the main motivation for people looking to decouple is to avoid having to pay fees like the ABSD.
For the uninitiated, ABSD is a tax that’s levied on top of Buyer’s Stamp Duty (a tax that property buyers have to pay when they buy a property), and it’s computed based on the valuation or the selling price of the property, whichever is higher. ABSD was first introduced in 2011 to manage the surge in demand for property and to keep housing prices affordable for Singaporeans.
ABSD applies differently to different groups of people according to nationality and residency status. Here is a brief breakdown:
To demonstrate, let’s say you’re a Singaporean citizen who is buying a $1 million property. You will be subjected to 12% ABSD.
The ABSD amount that you’ll need to pay is $1 million x 12% = $120,000.
With that said, decoupling is then a strategy that people use to avoid having to pay ABSD. In other words, the rule is to decouple, and purchase a property as your ‘first’ property again.
How much does it cost to decouple?
If decoupling will most definitely help a couple to save money, there would be no need to discuss this, and no need for the tons of articles debating on whether or not to decouple. The truth is, the process of decoupling incurs multiple costs.
Legal Fees
Legal documents need to be prepared to handle the purchase of property and transfer of ownership. The buyer will have to pay for the conveyancing fees. On the other hand, the seller needs to engage a lawyer to handle the transfer and sale of their share of the property. Typically, the two sets of lawyers would set you back $6,000 to $7,000.
Buyer Stamp Duty
Buyer’s Stamp Duty is tax paid on the acceptance of Option to Purchase (OTP) / Sale & Purchase Agreements (S&P). These are documents (i.e. OTP or S&P) that are prepared and signed when you buy or sell your property. Despite having part of the ownership of a property, the buyer would still have to buy for Buyer Stamp Duty during the decoupling process.
Seller Stamp Duty
If decoupling is done within the first three years of the property purchase, you’ll need to consider Seller Stamp Duty—12% of the price on the first year, 8% on the second year, and 4% on the third year. To avoid this, couples would wait for at least three full years before decoupling.
Penalties for Pre-payment
As strange as it sounds, this is a penalty for trying to pay off your home loan early. In the first three years, many home loans impose prepayment or early redemption penalties for homebuyers. This usually works out to 1.5% of the amount being prepaid. Be sure to check the terms and conditions of your home loan to avoid this additional fee.
CPF Refund
When you sell a property, you must return the amount you used from CPF with accrued interest when you sell the property. What this means is that you could end up with zero cash on hand. Worst still, your cash might end up being locked up in CPF and you will not have enough cash on hand to finance for your next property.
Two tips people wish they knew before decoupling
If you’ve been zoning out, here’s where you need to start paying attention. There have been many real estate regrets that people have. Many times, couples regret decoupling. Here are some things people wish they knew before they jumped straight into the decoupling process.
The cost of decoupling may add up to cost more than ABSD
When the costs of decoupling outweigh the ABSD cost, decoupling is not an economically viable option. This is especially so if the second property that you are buying is cheaper than the first. For a $1 million property, decoupling expenses can easily go up to $150,000 or more. In such cases, the 12% ABSD may be the better option. Furthermore, decoupling may not be the best solution for owners with multiple assets.
Calculation mistakes are common and very, very painful
Calculating the different amounts of ABSD based on your specific residential status and nationality can be a very stressful and confusing process. Mistakes are common! So, it is advised to engage a professional to handle the numbers for you.
Before you decide to decouple, consult a real estate agent or qualified financial advisor to work out your finances and options. Not only will they be able to decouple your properties to get the best returns, they will advise you on the best course of action for your specific situation.

The bottom-line
Purchasing a property is a big decision and a milestone in one’s life. It is completely normal that you are looking for ways and strategies to cut costs as much as possible. While decoupling is a strategy that many people employ to reduce the cost of their investment, many others find that decoupling may instead incur more costs than just paying ABSD.
To avoid having to pay more or to go through the processes and paperwork associated with decoupling for nothing, make sure you consult a professional and do your calculations before deciding on decoupling.
Moving Forward to 2025 Government Stand on Decoupling – Critical Advice Moving Forward: A 4-Point Plan
In 2025, a recent High Court case from June 2025, Jake v Millie, between two Singaporean owners has thrown a huge spotlight on the risks of this strategy. This is a must-know for every property agent.
The Story in a Nutshell: What Happened?
The Setup: A couple, Jake and Millie, bought a condo together. On paper, it was a 99/1 split, with Millie owning 99% and Jake owning 1%.
The Money: But here’s the twist – Jake paid for most of the property, far more than his 1% share. The main reason for the 99/1 split was to make Millie feel secure in the relationship as she was worried Jake would cheat on her.
The Breakup: The couple broke up. Millie claimed she owned 99% of the property as per the legal documents. Jake argued that since he paid for most of it, he should own most of it.
The Court’s Decision: The court sided with Jake. They looked past the 99/1 paper title and focused on who actually paid for the property. The judge decided that Millie was only holding a large portion of the property “in trust” for Jake. In the end, Jake was declared the true owner of over half the property (54.22%), not just his 1% share.
The Illegality: However the court also highlighted that the couple’s intended future decoupling and intention to pay stamp duty on only 1% share value constituted an illegal purpose being a breach of section 4 of the Stamp Duties Act.
Why This Case may be a Game-Changer for You.
This isn’t just a relationship drama; it has three major implications for all property transactions involving a 99/1 split.
1. The Paper Title Isn’t Everything
Firstly, the names and percentages on the title deed are not the final say. The law also cares about the financial reality and parties intentions behind the deal. If someone pays for 50% of a property, the court can decide they own 50% of it, even if the paper says they only own 1%. This is called a “resulting trust.”
2. The “Decoupling” Plan Can Lead to Serious Trouble with IRAS
We all know the “decoupling” plan: the 1% owner sells their share to the 99% owner, allowing them to buy a second property as a “first-time” buyer without ABSD.
This case exposes the danger. When the 1% owner sells their share, stamp duty is paid on the value of that 1%. But if they truly own 50% (because they paid for 50%), then they are under-declaring the value of their share to IRAS. The court made it clear that this is a form of unlawful understamping or false declaration to IRAS. IRAS has the power to investigate these deals, and the penalties can be severe.
The new case shows that when decoupling, it’s important that the stamp duty paid reflects the true ownership arrangement. If financial contributions don’t align with the 1% legal share, paying stamp duty on only the 1% value can create issues. To ensure everything is handled correctly, it is crucial for clients to seek specific legal advice.
3. The “ABSD loophole” is under the microscope.
The government and the courts are aware of these schemes. While the 99/1 split isn’t illegal by itself, using it with the sole intention of avoiding tax is a red flag. If it’s clear that a deal was structured just to get around ABSD, IRAS can disregard the arrangement and charge the full ABSD, plus a potential 50% surcharge.
Special Section: What if You Already Own a 99/1 Property and Want to Decouple Now
For owners who are in this situation, the stakes are higher. Here’s a step-by-step guide.
1. You MUST Re-evaluate Your True Ownership Share
The starting point is to figure out the real beneficial ownership. This isn’t about the 99/1 on paper; it’s about the money trail.
Action: Clients need to dig through all their financial records – bank statements, CPF payments, loan agreements—to calculate the exact percentage each person contributed to the property. This is a factor the Court may look at in determining their true share and ascertaining parties’ intentions.
2. Stamp Duty Must Be Paid on the TRUE Share
If the review shows the 1% owner actually funded, say, 40% of the property, then their beneficial share is 40%.
Action: When decoupling, stamp duty must be paid on the value of the 40% beneficial share being transferred, not the 1% legal share. Paying on 1% is understamping and a breach of the law. This can lead to paying the shortfall in tax plus heavy penalties.
3. The Original Purchase Can Still Be Audited by IRAS
Fixing the stamp duty now for the decoupling doesn’t erase all risks.
Action: IRAS can still investigate the original 99/1 purchase. If IRAS decides it was a scheme to avoid ABSD from the start, they can re-assess the tax for the initial purchase and impose a surcharge of up to 50%. There is no time limit for this.
4. The Critical Advice Moving Forward: A 4-Point Plan
Consider IRAS Adjudication First:
Before proceeding with the decoupling, clients can voluntarily seek adjudication from IRAS. This involves presenting their case to IRAS, who will then determine the correct amount of stamp duty to be paid. This is a proactive way to gain certainty and avoid future penalties for understamping.
Get Professional Help:
You must get independent legal advice to formalize their beneficial ownership and tax advice to ensure they are fully compliant, especially when preparing for adjudication.
Document Everything:
The reasons for the original split and the calculations for the true beneficial ownership must be well-documented. This is their defence if challenged.
Accept the Risk:
Clients must understand that while they can take steps to decouple correctly now (including adjudication), there is a lingering risk that the original transaction could be flagged by IRAS as a tax avoidance scheme.
