What Is the ABSD Remission for Married Couples?
When a married couple purchases a second residential property in Singapore, they are ordinarily liable for Additional Buyer’s Stamp Duty (ABSD) on the purchase price. As at Q2 2026, a married couple where at least one party is a Singapore Citizen (SC) would face a 20% ABSD on a second property.
However, IRAS provides a specific remission for married couples who are selling their existing HDB flat and purchasing a private residential property as an upgrade. The remission allows the couple to pay the ABSD upfront at the time of purchase and then claim a refund once the HDB flat is sold within the qualifying window — or in some cases, to defer the ABSD entirely subject to conditions.
Key framing: The remission is not an automatic exemption. The couple pays ABSD at the point of purchase and receives a refund only if they satisfy all conditions. The government holds the money as a security deposit on the couple’s commitment to sell their HDB flat.
Eligibility Conditions for the Remission
To qualify for the ABSD remission under the married couple upgrader scheme, all of the following conditions must be met at the time of purchase and within the window period:
1. At Least One Buyer Must Be a Singapore Citizen
The remission applies to married couples where at least one party holds Singapore Citizenship. SC-SPR married couples qualify. SC-foreigner married couples do not qualify for this remission (the foreigner buyer’s ABSD still applies separately).
2. The Couple Must Not Own Any Other Residential Property
At the point of purchasing the private property, the couple must not own any other residential property beyond their existing HDB flat. If either spouse owns a private property (locally or overseas), the remission does not apply to the new purchase.
3. The Existing HDB Flat Must Be Sold Within 6 Months
This is the most critical and most frequently missed condition. The existing HDB flat must be disposed of (sale completed, i.e. keys handed over) within 6 months from:
- The date of purchase of the private property (for completed properties — when the Option to Purchase is exercised), or
- The date of issue of the TOP or CSC (Certificate of Statutory Completion), whichever is earlier, for uncompleted (new launch) private properties.

Understanding the 6-Month Clock
The 6-month window starts from a different point depending on whether the client is buying a completed or uncompleted property.
| Property Type | 6-Month Clock Starts | HDB Sale Must Complete By |
|---|---|---|
| Completed resale private property | Date of purchase (OTP exercise) | Within 6 months of purchase date |
| New launch (uncompleted) private property | Date of TOP or CSC, whichever is earlier | Within 6 months of TOP or CSC, whichever is earlier |
For new launches, this is actually more forgiving — the couple can continue to live in their HDB flat throughout the construction period and only needs to sell after the private property is ready for occupation.
Common mistake: Agents sometimes miscount the window for resale purchases. The 6 months starts from when the OTP is exercised (the purchase date), not from when the couple collects the keys or moves in. For resale properties, the timeline can be tight if the couple has not yet found a buyer for their HDB flat.
The ABSD Payment and Refund Process
The procedural flow for the remission works as follows:
- Purchase the private property. The couple pays the full ABSD amount (currently 20% for SC first buyer, second property) at the point of exercising the OTP or signing the Sale and Purchase Agreement.
- Sell the HDB flat within the 6-month window. The couple completes the sale of their HDB flat (keys handed to buyer) within 6 months of the applicable start date.
- Apply for the refund. After the HDB sale is completed, the couple submits an ABSD refund application to IRAS with supporting documents (Sale and Purchase Agreement, Temporary Occupation Permit if applicable, HDB flat completion documents).
- IRAS processes the refund. If all conditions are met, IRAS refunds the ABSD paid, typically within a few weeks of the application.
What Happens If the 6-Month Deadline Is Missed?
If the HDB flat is not sold within 6 months, the couple forfeits the ABSD paid. IRAS does not grant extensions except in exceptional circumstances (such as a court order preventing the sale). The ABSD amount is retained and is not refundable.
On a SGD 2,000,000 private property purchase, the forfeited ABSD would be SGD 400,000. This is not a theoretical risk — it has happened to upgrader couples who could not sell their HDB flat in time due to market conditions, buyer financing failures, or delays in the legal process.
SC-SPR Married Couple Scenario
For SC-SPR married couples, the ABSD situation is more complex. The ABSD rates depend on which party is treated as the buyer and whether the purchase is in joint names.
As at Q2 2026, the ABSD rate for an SPR buying a second property is 30%. If an SC-SPR married couple purchases a property jointly and the SPR is named as co-purchaser, the higher SPR rate may apply. The remission conditions for SC-SPR couples purchasing as their second property should be verified directly with IRAS, as the applicable rate and refund mechanism depend on how the purchase is structured.
Agent action: For SC-SPR upgrader clients, direct them to seek legal and tax advice on the purchase structure before signing any OTP. The difference in ABSD liability between a sole SC purchase and a joint SC-SPR purchase can be material.
Alternative Strategy: Decoupling Before the Upgrade
Some upgrader couples explore decoupling as an alternative to the ABSD remission approach. Decoupling involves one spouse transferring their share of the HDB flat to the other spouse, so that one spouse is free from property ownership and can purchase the private property as a first-property buyer (no ABSD).
Decoupling has its own rules and costs — stamp duty on the transfer, eligibility conditions for HDB flats, and potential CPF accrued interest refund obligations. It is not always cheaper or simpler than the remission route, but it eliminates the 6-month deadline risk.
Refer to the LEVR Decoupling Guide for a fuller treatment of the decoupling option and when it makes sense versus the remission approach.
Pre-Transaction Checklist for Upgrader Clients
Before your client exercises the OTP on a private property while still owning an HDB flat, confirm all of the following:
- At least one spouse is a Singapore Citizen (SC-SC or SC-SPR couple)
- Neither spouse owns any other residential property (local or overseas) beyond the HDB flat
- The couple has a realistic plan and timeline to sell the HDB flat within 6 months of the private property purchase date (for resale private) or within 6 months of TOP (for new launch)
- The ABSD amount has been factored into the client’s cash planning — they will need to pay it upfront and wait for the refund after HDB sale
- The legal conveyancing timelines for both transactions (HDB sale + private purchase) have been discussed with a lawyer
- If the private property is a new launch, the couple understands that the 6-month window starts at TOP or CSC, whichever is earlier (typically TOP) — they do not need to sell the HDB flat during the construction period
Using LEVR to Model the Upgrade Scenario
LEVR’s ABSD Calculator allows you to check the ABSD liability for any buyer profile and property count instantly. For upgrader clients:
- Run the ABSD Calculator with the client as an SC buying their second property to see the full ABSD liability before remission
- Confirm with the client that their cash position covers the upfront ABSD payment (even if it is refundable) alongside the down payment
- Model the timeline risk: what happens to the client’s financial position if the HDB sale is delayed and the ABSD refund is deferred?
Coming into a client meeting without these numbers means you cannot answer the first question every upgrader asks: “Do I need to pay ABSD and will I get it back?”
