The Expensive Lesson on Seller's Stamp Duty (SSD)
This is my first post here, so I thought I'd start with something that stayed with me — a property transaction involving a surprisingly large Seller's Stamp Duty bill, and a few sleepless nights.
Some deals teach you something even when you've done your checks. This was one of them.
Before a buyer signs an Option to Purchase (OTP), I check the ownership history. It's part of the due diligence I carry out when acting for a buyer.
My buyer was purchasing a private property for around $2 million. The records showed a change in ownership about two years earlier, so SSD appeared to be applicable.
I asked the seller's co-broke agent to confirm that the seller was aware. He told me he had checked and that the seller knew.
So my buyer paid the 1% deposit and received the OTP.
On the day my buyer went to the law firm to exercise the option and pay the remaining 4%, the lawyer asked me to confirm once more that the seller was aware that the SSD would be 8% — at the time, roughly $160,000.
I said yes.
But 8% is a big number, so I called the co-broke agent again, right there at the law firm. This time, he sounded shocked.
My impression was that the seller had been told that SSD would apply, but perhaps not that the applicable rate was 8%. His answer was still to proceed, as the seller had already given the go-ahead.
My buyer exercised the option.
Two days later, the co-broke agent called to ask whether the exercise date could be delayed because the 8% SSD was more than the seller had expected.
By then, however, the option had already been exercised and the bank had endorsed the cashier's order.
Looking at the ownership records, I suspected there may have been a misunderstanding about the applicable holding period or SSD rate.
I turned to my client's lawyer, who took the matter very seriously. At that stage, changing the exercise date could have created legal and tax issues, so I was advised that we should proceed according to the agreed timeline.
I was acting for the buyer, so my responsibility was to protect my buyer's interests. I wasn't representing the seller, and I had done my checks.
Still, the situation weighed on me, and I lost a few nights of sleep.
I just hoped the co-broke agent wouldn't have to pay for this lesson.
A few things worth double-checking before an OTP
For sellers
Check whether SSD applies to your property and confirm the applicable amount with your lawyer before agreeing to a sale.
Check the relevant purchase and sale dates carefully. The applicable SSD rules depend on the acquisition date, disposal date and the SSD regime in force at the time. IRAS sets out the specific rules and dates in its SSD guidance (for Residential Property).
Plan your timeline around the applicable holding period. Don't assume that being "around two years" into ownership automatically means a particular SSD rate applies.
For buyers
Verify ownership information through official records, such as SLA's INLIS, rather than relying solely on verbal confirmation.
If there has been a recent change in ownership, it is reasonable to ask the seller's side to confirm whether SSD applies and whether the seller has obtained the appropriate advice on the amount payable.
If a significant SSD amount may be involved, make sure the key figures and dates have been properly checked before committing to the transaction.
For everyone
Re-confirm the important dates and figures at each milestone — before the OTP, and again before the option is exercised.
A verbal "yes, it's been checked" may not be enough when the amount involved is significant.
One important update
This experience took place before 4 July 2025. Singapore's SSD rules have since changed, so the 8% rate mentioned in this story should not be used to determine the SSD payable for a current or future transaction. Please refer to the latest IRAS guidelines for the rules applicable at the time of your transaction.
For residential properties acquired between 11 March 2017 and 3 July 2025, the SSD rates were 12% if disposed of within 1 year, 8% if disposed of after more than 1 year but within 2 years, and 4% if disposed of after more than 2 years but within 3 years.
For properties acquired on or after 4 July 2025, the holding period was extended to 4 years and the SSD rates were revised to 16%, 12%, 8% and 4% across the four-year holding period.
These are the rules applicable at the time of writing. As SSD rules may be revised from time to time, please refer to the latest IRAS guidelines when considering a current transaction.
So if you're reading this at a later date, don't use the 8% figure in my story to work out your own SSD.
The applicable SSD depends on the specific circumstances, including the property type, acquisition date and disposal date.
For the latest rules and calculation guidance, please refer to IRAS — Seller's Stamp Duty (SSD) for Residential Property.
The lesson I took away
Cross-check the dates, figures and key terms — not just once, but again before the important milestones.
And when a number as significant as SSD is involved, don't rely on a verbal confirmation alone. Make sure everyone is clear on the amount and that the appropriate professional advice has been obtained where needed.
I hope sharing this experience helps someone avoid the same worry.
