Decoupling Property in Singapore (2026): ABSD Savings, BSD, SSD and the Rules That Apply

Decoupling means one spouse sells their share of a jointly owned private home to the other, so the seller can buy again as a first-timer. A Singapore Citizen then pays 0% ABSD, instead of the 20% a couple pays on a joint second home. The costs are BSD on the share, possible SSD and a CPF refund.

Updated 27 September 2026. ABSD rates have not changed since 27 April 2023. SSD rates and holding periods changed for homes bought on or after 4 July 2025.

What are the ABSD rates in 2026?

These are the IRAS rates for purchases on or after 27 April 2023. They are still in force.

When two or more buyers with different profiles buy together, IRAS applies the highest rate among them to the whole price. A property you own even partly counts as one whole property. This is why a couple who own one home jointly both count as owning one property.

How does decoupling work?

1. One spouse sells their share of the home to the other spouse at market value.
2. The spouse who buys the share now owns the whole home. IRAS says that a Singapore Citizen who owns only that one property and buys more of it from a co-owner pays no ABSD on that purchase. They still pay BSD on it.
3. The spouse who sold now owns no residential property. IRAS removes a property from your count once there is a contract to sell it and the buyer has exercised the option. A Singapore Citizen in this position pays 0% ABSD on their next home.

The rule in step 2 depends on the buyer's profile. If the spouse buying the share is a PR, or already owns another property, different rates and a partial remission may apply. See IRAS's page on the acquisition of additional interest.

How much does decoupling cost?

Buyer's Stamp Duty on the share. IRAS charges BSD on the higher of the price paid or the market value of the share. The residential rates since 15 February 2023 are:

Seller's Stamp Duty. The spouse who sells pays SSD if their share is sold within the holding period. For homes bought on or after 4 July 2025, SSD is 16%, 12%, 8% or 4% if you sell within one, two, three or four years of buying. For homes bought between 11 March 2017 and 3 July 2025, it is 12%, 8% or 4% within three years. SSD is charged on the higher of the price or the market value of the share.

CPF refund. The spouse who sells must put back into their CPF account the CPF money they used on the property, plus accrued interest (CPF Board). This money isn't lost, because it goes back to their own CPF. But the buying spouse needs cash or CPF to pay for the share.

Loan. MAS requires the borrower on a housing loan to also be a mortgagor of the property, so the first home's loan must move into the buying spouse's sole name. Their total debt repayments must stay within the 55% total debt servicing ratio (TDSR). If someone else is brought in to help meet TDSR, MAS treats that person as a co-borrower, and lower LTV limits apply to their future housing loans. The spouse who sold has no outstanding housing loan, so MAS allows them to borrow up to 75% of the next home's value, with at least 5% paid in cash. With one outstanding housing loan, the limit drops to 45% and at least 25% must be paid in cash.

Legal and valuation fees also apply. They vary by firm, so we have not estimated them here.

Is decoupling still worth it? A worked example

SG Properties estimate, using IRAS rates as at 27 September 2026. A married couple, both Singapore Citizens, jointly own one condo valued at S$2,000,000. They bought it more than four years ago, so no SSD applies. They want to keep it and buy a S$2,500,000 home.

Working: BSD on S$1,000,000 is S$1,800 + S$3,600 + S$19,200 = S$24,600. BSD on the S$2.5 million home is the same in both cases, so we leave it out.

The saving is large, but it comes with conditions:

• Each loan normally rests on one spouse's income. The spouse who sold finances the new home under TDSR, and the other spouse carries the first home's loan. If either spouse helps the other meet TDSR, MAS counts them as a co-borrower, which lowers the LTV limit on their own loan.
• Ownership becomes separate. Each home is owned by one spouse only, and that affects who controls a sale and what happens under a will or intestacy. Get legal advice.
• ECs and HDB flats. For 30 months after selling private residential property, you cannot apply to buy a new EC (HDB). This guide covers private homes only. HDB flats and ECs have their own ownership rules, and EC owners cannot buy another residential property during the MOP.

If you plan to sell the first home anyway, you may not need to decouple. IRAS refunds the ABSD on a couple's joint second home if they sell the first one within 6 months of buying the second (for a completed home), or within 6 months of TOP or CSC (for an uncompleted one). Other conditions apply: the couple must include a Singapore Citizen and buy in both names only.

Does IRAS treat decoupling as tax avoidance?

IRAS says it "takes a stern view" of arrangements made to reduce or avoid stamp duty. Under Section 33A of the Stamp Duties Act, the Commissioner can disregard such an arrangement, recover the duty owed and add a 50% surcharge. Penalties of up to four times the unpaid amount can follow if these are not paid on time. IRAS also says it may use Section 33A if a sale of a previous property looks "fictitious" and was set up to avoid ABSD.

The best-known cases involve "99-to-1" purchases, where a new home is bought in two steps to reduce ABSD. In a reply to Parliament on 7 May 2024, Lawrence Wong, then Deputy Prime Minister and Minister for Finance, said IRAS had reviewed 187 such cases and found tax avoidance in 166. About S$60 million in ABSD and surcharges would be clawed back. That reply dealt with 99-to-1 purchases and did not discuss decoupling an existing home. A decoupling transfer should be a real sale at market value. Get legal advice before you start.

FAQ

Do I pay ABSD when my spouse sells me their share of our home?

If you are a Singapore Citizen and this is the only residential property you own, IRAS says no ABSD is payable when you buy more of it from a co-owner. BSD is still payable.

How much BSD is payable on decoupling?

BSD is charged on the higher of the price or the market value of the share, at 1% to 6%. On a S$1,000,000 share, it is S$24,600.

Does SSD apply when decoupling?

Yes, if the spouse who sells is still within the SSD holding period. That period is four years (4% to 16%) for homes bought on or after 4 July 2025, and three years (4% to 12%) for homes bought between 11 March 2017 and 3 July 2025.

What ABSD does the spouse who sold pay on the next home?

Once the transfer contract is in place, they own no residential property. A Singapore Citizen pays 0% ABSD and a PR pays 5% on their next home, plus BSD.

Is decoupling the same as a 99-to-1 purchase?

No. A 99-to-1 purchase splits ownership of a new home to reduce ABSD. IRAS has treated many of these as avoidance under Section 33A. Decoupling is the sale of a share in a home you already own. IRAS's anti-avoidance powers still apply to any arrangement it finds contrived.
