When preparing to purchase a premier Singapore new launch condominium such as One Chuan Grove along Lorong Chuan in District 19, capital planning extends far beyond the headline developer price. In Singapore's property taxation framework, transaction costs—specifically Buyer's Stamp Duty (BSD) and Additional Buyer's Stamp Duty (ABSD)—form a critical portion of the upfront liquid capital required to secure a home.
As an amalgamated mega-development of 1,056 homes spanning 326,638 sq ft by SGX Mainboard-listed Sing Holdings and Sunway Developments, One Chuan Grove offers a comprehensive mix from 1-bedroom to 5-bedroom layouts. With an underlying combined GLS land cost of S.3275 billion (S,355 psf ppr land rate) and estimated prices ranging from ~S.25M for 1-bedroom units to ~S.95M for 5-bedroom residences, calculating your exact tax exposure is essential before booking.
Following our analyses of One Chuan Grove vs Chuan Park pricing, floor plans and unit mix, and the HDB upgrader progressive payment roadmap, this guide breaks down BSD calculation tiers, ABSD rates across buyer residency profiles, married couple remission rules, restructuring considerations, and CPF Ordinary Account timelines.
1. Singapore Stamp Duty Framework: BSD vs ABSD for New Launches
Under the Stamp Duties Act administered by the Inland Revenue Authority of Singapore (IRAS), property purchases are subject to two key stamp duty levies:
- Buyer's Stamp Duty (BSD): Payable by all property buyers regardless of nationality or existing property count. BSD is calculated on the higher of the purchase price or the open market value of the property.
- Additional Buyer's Stamp Duty (ABSD): An anti-speculation measure levied on top of BSD based on the buyer's residency status (Singapore Citizen, PR, Foreigner, or Entity) and existing property count.
For buyers purchasing during the February 2027 launch preview at One Chuan Grove, stamp duty is payable within 14 days of exercising the Sales & Purchase Agreement (S&PA). Missing this statutory deadline incurs severe IRAS late penalties, making advance liquid capital planning indispensable.
2. Buyer's Stamp Duty (BSD) Tiers & Calculations for One Chuan Grove
Following Singapore Budget 2023 adjustments, high-value residential properties are subject to a progressive 6-tier BSD schedule:
- First S80,000: 1% (S,800)
- Next S80,000 (S80,001 – S60,000): 2% (S,600)
- Next S40,000 (S60,001 – S,000,000): 3% (S9,200)
- Next S00,000 (S,000,001 – S,500,000): 4% (S0,000)
- Next S,500,000 (S,500,001 – S,000,000): 5% (S5,000)
- Amounts above S,000,000: 6%
The standard formula for properties between S.5M and S.0M is: (5% of Purchase Price) - S0,400. For units exceeding S.0M, the formula is: (6% of Purchase Price) - S0,400.
| Unit Typology | Estimated Area | Indicative Price (SGD) | Buyer's Stamp Duty (BSD) | Effective BSD Rate |
|---|---|---|---|---|
| 1-Bedroom | ~474 sq ft (44 sqm) | S,250,000 | S4,600 | 2.77% |
| 2-Bedroom / 2BR+Study | 581 – 710 sq ft | S,650,000 | S2,100 | 3.16% |
| 3-Bedroom / 3BR+Flexi | 807 – 1,001 sq ft | S,180,000 | S8,600 | 3.61% |
| 4-Bedroom / 4BR Luxury | 1,076 – 1,356 sq ft | S,950,000 | S17,100 | 3.97% |
| 5-Bedroom Luxury | ~1,561 sq ft (145 sqm) | S,950,000 | S76,600 | 4.47% |

3. Additional Buyer's Stamp Duty (ABSD) Tiers & FTA Treatment
Additional Buyer's Stamp Duty is determined by citizenship and existing residential holdings under IRAS rules:
- Singapore Citizens (SC): 1st property: 0% | 2nd property: 20% | 3rd & subsequent: 30%
- Singapore Permanent Residents (SPR): 1st property: 5% | 2nd property: 30% | 3rd & subsequent: 35%
- Foreigners (Non-PR): Flat 60% on any residential property purchase.
- Entities & Trusts: Flat 65% on all residential acquisitions.
Free Trade Agreement (FTA) Exemption: Under Free Trade Agreements, nationals and permanent residents of Iceland, Liechtenstein, Norway, Switzerland, and Nationals of the United States of America (US Citizens) receive equal treatment to Singapore Citizens. For expatriates from the Australian International School (AIS) or regional business parks holding eligible nationality, a 1st residential purchase at One Chuan Grove attracts 0% ABSD.
4. ABSD Remission Rules for Married Couples Upgrading
Many local households purchasing One Chuan Grove are upgrading from mature HDB flats in Bishan or Serangoon. To avoid interim rental housing, married couples can qualify for full ABSD remission under IRAS rules:
- Joint Purchase: The unit must be bought jointly by a legally married couple, where at least one spouse is a Singapore Citizen.
- Sole Existing Property: The couple must own only one residential property at the time of purchasing One Chuan Grove.
- 6-Month Disposal Timeline: The existing property must be sold within 6 months from the Temporary Occupation Permit (TOP) date or legal completion of One Chuan Grove, whichever is earlier.
- Marriage Continuity: The couple must remain married without acquiring other residential properties prior to disposal.
Upfront Cash Flow Note: The 20% ABSD must still be paid upfront within 14 days of exercising the S&PA. IRAS disburses the full refund only after the first home is sold within the 6-month window. Furthermore, the previously enforced 15-month wait-out period for private property owners buying non-subsidized HDB resale flats has been formally scrapped, ensuring flexible transition options.
5. Decoupling vs 99-to-1 Structuring: Compliance & IRAS Scrutiny
Homeowners often explore legal ownership structures to optimize tax liabilities when acquiring a second home:
- Legitimate Part-Purchase Decoupling: For couples co-owning a private condo, one spouse can buy out the other's share at market value. The exiting spouse then enters One Chuan Grove as a first-time buyer with 0% ABSD and full 75% LTV mortgage eligibility. Upgraders can explore detailed asset structuring frameworks at Pat Ko Property.
- 99-to-1 Audit Clampdown: IRAS vigorously audits artificial 99-to-1 arrangements executed to evade ABSD under Section 33A of the Stamp Duties Act. Non-genuine fractional schemes face full ABSD clawbacks plus a mandatory 50% surcharge. Buyers must ensure all joint ownership structures reflect genuine financial equity.
6. Payment Milestones & Deploying CPF Ordinary Account for Stamp Duty
Under the Normal Progressive Payment Scheme (NPS), the initial capital outflow proceeds along statutory milestones:
- Booking Fee (5% Cash): Payable on booking day to secure the Option to Purchase (OTP).
- Exercise Fee (15% Cash/CPF): Payable upon signing the S&PA within 3 weeks of document delivery.
- Stamp Duty (BSD + ABSD): Payable within 14 days of exercising the S&PA.
Deploying CPF OA Funds: CPF Ordinary Account savings can be applied towards BSD and ABSD. However, because CPF Board drawdown requires prior legal processing, conveyancing lawyers must receive CPF instructions early. If CPF funds cannot clear before the 14-day deadline, buyers must pay via cash/cashier's order first and seek CPF reimbursement post-completion.
