Enter a purchase price and a buyer profile to compute the full stamp duty on a One Chuan Grove purchase — Buyer’s Stamp Duty on the current tiered scale plus Additional Buyer’s Stamp Duty for that profile, using the rates detailed on the stamp duty page.
Both duties are payable within 14 days of exercising the Option. Nationals and permanent residents of the United States, and nationals of Iceland, Liechtenstein, Norway and Switzerland, receive Singapore Citizen treatment under free trade agreements — select the matching citizen row. Married couples with at least one citizen spouse, where neither owns residential property, qualify for full ABSD remission; on a second property a refund may be claimed if the first is sold within six months — strict IRAS conditions apply. Rates per IRAS, verified 18 September 2026.
The purchase price above defaults to a round $1,500,000 purely so the calculator has a figure to work from. It is an illustration and bears no relation to One Chuan Grove, whose pricing is released by the developer in due course.
The profile choice dominates the arithmetic. On the same unit, a first-home citizen and a second-property citizen can be hundreds of thousands of dollars apart in total duty, which is why upgraders plan the sequence: selling before exercising restores the zero-per-cent band and the 75 per cent LTV ceiling at the same time.
Married couples with at least one Singapore Citizen spouse may also qualify for the ABSD refund when replacing a first home, subject to strict timelines. Stack this result with the maximum loan and the staged payment schedule for the complete picture, or ask the Sales Concierge to walk through a specific scenario.
