How Much Does Decoupling Cost in Singapore?
Quick answer:
Decoupling costs buyer’s stamp duty on the transferred share, two sets of legal fees, a valuation and any loan charges. Seller’s stamp duty applies only inside the holding period, and ABSD only in specific cases.
The total moves with the share’s value. The CPF refund isn’t a cost: it goes back into your own CPF account.

Decoupling cost breakdown: what you actually pay
The largest cost in most decouplings is buyer’s stamp duty on the share being transferred. Everything else is smaller, and two duties apply only in certain cases.
Buyer's stamp duty on the transferred share
The staying owner pays BSD on the share they take over.
IRAS assesses BSD on the higher of the price or the market value, so a transfer priced below market does not lower the duty.
The tiers apply to the share’s value, not the whole property.
| Portion of the share's value | BSD rate |
|---|---|
| First S$180,000 | 1.0% |
| Next S$180,000 | 2.0% |
| Next S$640,000 | 3.0% |
| Next S$500,000 | 4.0% |
| Next S$1,500,000 | 5.0% |
| Above S$3,000,000 | 6.0% |

ABSD, only in specific cases
A Singapore Citizen who owns only this home pays no ABSD on taking over the co-owner’s share, IRAS confirms.
ABSD applies if the staying owner already holds another residential property.
A permanent resident pays ABSD on the share, which IRAS remits down to the first-home rate.
Check your profile on the stamp duty calculator.
Seller's stamp duty, only inside the holding period
The exiting owner pays SSD only if their share changes hands within the holding period.
IRAS counts each part from the date it was acquired, so the clock runs from when the exiting owner bought in.
| Holding period | Bought 11 Mar 2017 to 3 Jul 2025 | Bought on or after 4 Jul 2025 |
|---|---|---|
| Up to 1 year | 12.0% | 16.0% |
| 1 to 2 years | 8.0% | 12.0% |
| 2 to 3 years | 4.0% | 8.0% |
| 3 to 4 years | 0.0% | 4.0% |
| Over 4 years | 0.0% | 0.0% |
Legal fees, valuation and loan costs
You pay two sets of legal fees. Singapore’s conveyancing rules generally stop one law firm acting for both sides of the same sale, so each owner appoints their own.
Ask two firms for quotes.
A valuation sets the market value that both duties and the CPF sums rest on.
If the loan is still in its lock-in period, the bank may charge a redemption fee.
The staying owner then refinances in one name and must qualify alone; the affordability calculator shows where you stand.
Is the CPF refund a cost of decoupling?
No. The CPF refund is the exiting owner’s own money going back into their own CPF account.
CPF requires the amount used, plus accrued interest, to be refunded when a share is sold.
Back in the Ordinary Account it keeps earning, at 2.5% a year from October to December 2026, and can be used again for the next home within CPF’s rules.
It is retirement money returning to where it belongs.
What the refund changes is cash in hand.
The exiting owner receives the share price, less their part of the loan, less the CPF refund.
A large refund can mean less cash for the next downpayment, even though nothing has been lost.
If the proceeds fall short of the full refund, a sale at market value doesn’t need a cash top-up; CPF applies a formula instead. So the refund belongs in the plan for the next move, not on the cost list.
Is decoupling worth it? How to work out the break-even
In cost terms, decoupling is worth it when the friction of the transfer is smaller than the ABSD it removes from the next purchase.
That answer is specific, not general.
It moves with the share’s valuation, the loan against it, how much CPF each owner used, and the price of the next home.
| Item | Illustrative figure |
|---|---|
| Condo valuation | S$2,000,000 |
| Share transferred (50%) | S$1,000,000 |
| BSD on the share | S$24,600 |
| ABSD (citizen, no other home) | S$0 |
| SSD (bought 2018) | S$0 |
| Legal fees, valuation, loan charges | Your quotes |
| ABSD otherwise due on a S$1,500,000 second home | S$300,000 |
Note: These figures are illustrative and opinion-based, produced with calculation tools — not a valuation or financial advice. Human error is possible; verify against official sources before relying on them.
The BSD is 1.0% of S$180,000, 2.0% of the next S$180,000 and 3.0% of the remaining S$640,000.
The S$300,000 is 20% ABSD on a citizen’s second home.
Here the duty is a small fraction of the ABSD removed.
The second test is funding: whether the exiting owner’s cash and restored CPF cover the next downpayment, and whether each owner passes the loan test alone.
IRAS assesses the duty and your conveyancing lawyer handles the transfer. My part is the property side: financing, which asset, the order of moves and the exit.
Decoupling is one route. Here's the other.
Selling the home and buying two also frees a name, and it suits different owners.
Neither route frees more by default.
Which releases more depends on the share’s valuation, the loan against it and how much CPF each owner used, and not every owner used CPF.
Run the sums on both before choosing.
| Factor | Decouple | Sell one, buy two |
|---|---|---|
| What changes hands | One share | The whole property |
| The home | Keep one you value, which may be hard to find again | Change size, location or age |
| Disruption | No sale commission, no move | A sale, a purchase and a move |
| Next loans | Staying owner refinances alone | Two names, two first housing loans |

Should you decouple or sell?
Now that the costs are on paper, the next question is whether this is a home you want to keep.
The short self-assessment below sorts the factors that point each way, so you can see where your situation leans.
Two short steps. First, whether each route can be financed. Then, where your reasons for moving actually sit.
Answer the three questions in Step 1 to continue.
With both limits in place, the picture below is background rather than a plan.

@agent_rick_longDecoupling next steps: five figures to gather
Five figures decide what decoupling costs you and whether it breaks even. Gather these before you speak to a lawyer or a bank:
- A recent valuation of the whole property
- The outstanding loan, and whether it is still in its lock-in period
- How much CPF each owner used, plus accrued interest (shown on your CPF home ownership dashboard)
- The date you bought, which decides any SSD
- The price of the next home you have in mind
With those five in hand, the sum is short work — and the decision stays yours.
What's left is the part no guide can do — your own figures. Send me the valuation and your outstanding loan, and I'll work out whether it breaks even.

Common questions about decoupling costs
Can we transfer the share at a lower price to cut the stamp duty?
No. IRAS assesses BSD on the higher of the price or the market value, so a lower price doesn't lower the duty. SSD on the exiting owner's share works the same way.
Do we need two lawyers to decouple?
Yes. Singapore's conveyancing rules generally stop one firm acting for both the buyer and the seller in the same sale, so each owner appoints their own. Get quotes from two firms.
Does the CPF refund come back to us in cash?
No. It goes back into the exiting owner's CPF account with accrued interest, where it keeps earning and can be used toward the next home within CPF's rules. Only what's left after the loan and the refund is paid in cash.
