Additional Buyer's Stamp Duty is the single largest line item most Singapore property buyers underestimate. It is not bracketed like income tax it is a flat percentage of the full purchase price, due within 14 days of exercising the Option to Purchase, and it sits on top of standard Buyer's Stamp Duty. Get the ABSD calculation wrong on a $1.8M second property and you're off by $360,000, not a rounding error.
I've built this hub because ABSD questions almost never arrive as "what's the rate." They arrive as "can I avoid this," "does my situation qualify for remission," "should we decouple," or "what happens if I inherit a flat I didn't ask for." Every article below answers one of those actual questions, verified against current IRAS and HDB rules. I organise every client conversation around three questions, and I've grouped the reading the same way:
What does ABSD actually cost on this specific purchase, and is there a legitimate remission, FTA exemption, or structure that reduces it?
Is there a disposal window, a remission deadline, or a sequencing decision (sell first vs retain) that determines whether you pay ABSD at all?
Is the structure you're considering (99 to 1, trust, decoupling) actually defensible under IRAS scrutiny, or does it create more risk than the ABSD it saves?

Frequently asked questions
What is ABSD and when is it due?
Additional Buyer's Stamp Duty is a flat percentage of the full purchase price, not bracketed like income tax, and it sits on top of standard Buyer's Stamp Duty. It is due within 14 days of exercising the Option to Purchase.
How much can ABSD add to a second property purchase?
Get the calculation wrong on an $1.8M second property and you can be off by $360,000, not a rounding error. It is the single largest line item most Singapore property buyers underestimate.
What is the highest ABSD rate, and who pays it?
Rates run as high as 60% for foreign buyers. Trust purchases attract an even higher 65% rate, the highest band on the schedule, though a trust can still make sense in some situations despite it.
What are the legitimate ways to reduce ABSD?
Every legitimate lever sits under one of three questions: is there a remission, FTA exemption or structure that lowers the bill (Money); does a disposal window or sequencing decision avoid it altogether (Timing); and is a structure such as 99 to 1 or decoupling actually defensible under IRAS scrutiny (Safety).
What is the disposal window for ABSD remission?
Remission and refund timing is the most common way buyers forfeit a legitimate claim, and the 6 month disposal window is the deadline most often missed. Separate deadlines also apply to filing the refund claim with IRAS and to how ABSD applies on inherited property.
