Singapore Stamp Duty: What Buyers & Aspiring Agents Must Know

TL;DR: Singapore stamp duty is a mandatory tax on property documents, consisting of Buyer’s Stamp Duty (BSD), Additional Buyer’s Stamp Duty (ABSD), and Seller’s Stamp Duty (SSD). For property buyers, it is a significant upfront cost, while for RES exam candidates, it is a core component of the Paper 2 Taxation syllabus.

Every property purchase in Singapore attracts Buyer’s Stamp Duty (BSD), regardless of the buyer's nationality. BSD is calculated based on the purchase price or the market value of the property, whichever is higher. As of the latest adjustments, the residential BSD rates are tiered: 1% on the first $180,000, 2% on the next $180,000, 3% on the next $640,000, 4% on the next $500,000, 5% on the next $1,500,000, and 6% on any amount exceeding $3,000,000.

For RES exam candidates, mastering these tiers is essential for the Taxation section of Paper 2. You will often be required to manually calculate the BSD for a given property price without a stamp duty calculator. For example, a $2 million property would incur a BSD of $69,600. Understanding the Estate Agents Act (Cap. 95A) and the role of the Inland Revenue Authority of Singapore (IRAS) in tax collection is fundamental to your professional practice.

Buyer’s Stamp Duty is a progressive tax applied to all property transactions in Singapore, ensuring that higher-value acquisitions contribute more to national revenue. Candidates must memorize the specific percentage tiers and thresholds to accurately advise clients and pass the Paper 2 Taxation module with the required 75% score.

The ABSD Singapore framework is a critical cooling measure designed to manage demand and ensure housing remains affordable. Unlike BSD, ABSD rates depend heavily on the buyer's profile—specifically their residency status and the number of residential properties they already own. According to the CEA Annual Report, staying updated on these regulatory shifts is a core competency for the 33,000+ registered agents in Singapore as of 2026.

Buyer Profile	1st Property	2nd Property	3rd & Subsequent
Singapore Citizens (SC)	0%	20%	30%
Singapore Permanent Residents (SPR)	5%	30%	35%
Foreigners (FR)	60%	60%	60%
Entities / Trustees	65%	65%	65%

For RES exam candidates, this topic falls under Taxation in Paper 2. You can practice questions on this in the Prepare app. It is vital to note that under Free Trade Agreements (FTAs), nationals or residents of certain countries (like the USA or Switzerland) may be eligible for the same ABSD treatment as Singapore Citizens.

Additional Buyer’s Stamp Duty (ABSD) serves as a significant financial barrier for property investors and foreign buyers, with rates reaching as high as 60% for non-citizens in 2026. Aspiring agents must accurately identify buyer profiles to provide correct financial advice and avoid professional negligence under CEA regulations.

While BSD and ABSD affect buyers, the Seller’s Stamp Duty (SSD) targets those looking to sell residential property shortly after acquisition. The primary goal of SSD is to curb short-term 'flipping' and stabilize the market. The duty is payable if a residential property is sold within a three-year holding period.

The rates are strictly time-dependent: 12% if sold within the first year, 8% within the second year, and 4% within the third year. After three years, the SSD rate drops to 0%. Candidates studying for the stamp duty RES exam questions must be careful with dates, as the holding period is calculated from the date of acquisition (usually the Option to Purchase date) to the date of disposal.

In the context of HDB Properties, SSD applies in addition to the Minimum Occupation Period (MOP) rules, though most HDB owners will have cleared the three-year SSD window by the time their five-year MOP concludes.

Seller’s Stamp Duty is a cooling measure designed to curb short-term property flipping in Singapore. It applies to residential properties sold within three years of purchase, with rates decreasing from 12% in the first year to 4% in the third year, ensuring market stability and long-term investment focus.

The Real Estate Salesperson (RES) Examination is known for its rigor, with a typical pass rate of approximately 45% according to 2025 industry benchmarks. To become one of the 33,000+ registered agents, candidates must pass two papers, each consisting of 40 MCQs. Paper 2 is particularly calculation-heavy, covering Sale of Properties and Taxation.

In 2026, the registration fee for the exam is S$408.55 (inclusive of GST). To succeed, you must achieve a passing score of 75% (60 out of 80 questions total). The Taxation topic alone accounts for a significant portion of Paper 2, with 116 practice questions available in the Prepare app to help you master BSD, ABSD, SSD, Property Tax, and GST.

Candidates often struggle with the distinction between 'Contract Date' and 'Completion Date' when calculating stamp duty deadlines. Remember, stamp duty must be paid within 14 days of the execution of the sale agreement (if signed in Singapore).

The RES exam requires a 75% passing threshold, making the Taxation module a critical area for candidates to master. Understanding the nuances of stamp duty calculations and timelines is essential for passing Paper 2 and securing a license from the Council for Estate Agencies in 2026.

How much is the RES exam fee in 2026? The registration fee is S$408.55 (inclusive of GST) for both papers. Candidates who need to retake a single paper pay a reduced fee, but most aim to pass both in one sitting to begin their career quickly.

Is a stamp duty calculator allowed during the RES exam? While you cannot use an online stamp duty calculator, you are permitted to use a physical, non-programmable calculator. You must be able to calculate tiered BSD and varying ABSD rates manually based on the scenarios provided in the exam booklet.

What is the passing score for the RES exam? You must score at least 75% in both Paper 1 and Paper 2. This high bar ensures that all registered agents possess a deep understanding of the Planning Act and Land Titles Act.

How long should I study for the RES exam? Most successful candidates dedicate 2 to 4 months of intensive study. Given the 45% pass rate, utilizing practice questions for all 13 topics, including Taxation, is highly recommended for exam readiness.

Achieving the 75% passing score on the RES exam requires a comprehensive understanding of Singapore's property tax laws and transaction procedures. Candidates should focus on high-weightage topics like stamp duty and HDB regulations to ensure they meet the rigorous standards set by the Council for Estate Agencies.

To excel in both the RES exam and your future career as a property agent, you must go beyond rote memorization. Practice applying stamp duty rules to complex scenarios, such as 'decoupling' or purchases involving multiple buyers with different residency statuses. For example, if a Singapore Citizen and a Foreigner buy a property together, the higher ABSD rate of 60% typically applies to the entire purchase price.

Always refer to official resources like the IRAS website for the most current tax circulars and the CEA website for regulatory updates. In the exam, read the questions carefully—sometimes the 'purchase price' and 'market value' differ, and you must always calculate duty based on the higher amount.

For RES exam candidates, this topic falls under Taxation in Paper 2. You can practice questions on this in the Prepare app, which offers over 2,000 practice questions across all 13 RES exam topics to ensure you are fully prepared for the Computer-Based Test (CBT) format.

Mastering stamp duty involves understanding the tiered calculation of BSD, the residency-based application of ABSD, and the time-sensitive nature of SSD. This knowledge is vital for passing the RES exam and providing professional, accurate financial advice to clients in Singapore’s dynamic and highly regulated real estate market.
