ABSD, BSD, and SSD: Complete Taxation Guide for the RES Exam

TL;DR: Stamp duty is a tax on documents relating to immovable properties in Singapore, consisting primarily of Buyer’s Stamp Duty (BSD), Additional Buyer’s Stamp Duty (ABSD), and Seller’s Stamp Duty (SSD). For the RES exam, candidates must be able to calculate these duties based on the higher of the purchase price or market value.

Buyer’s Stamp Duty (BSD) is payable by all property buyers, regardless of nationality or property count. Under the current IRAS (opens in a new tab) framework, residential property 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. Non-residential properties follow a different schedule, peaking at 5% for the portion exceeding $1,500,000.

For RES exam candidates, this topic falls under Taxation in Paper 2. You can practice questions on this in the Prepare app. Mastery of the BSD calculator logic is essential for Paper 2 Section B, where case studies often require precise multi-tier calculations to determine the total acquisition cost for a buyer. A common exam pitfall is forgetting that BSD applies to both residential and commercial transactions, whereas ABSD is specific to residential property.

Buyer's Stamp Duty (BSD) is a mandatory tax on all property acquisitions in Singapore, calculated using a tiered rate system applied to the higher of the purchase price or market value, with residential rates currently topping out at 6% for properties valued above $3 million.

Additional Buyer’s Stamp Duty (ABSD) was introduced as a cooling measure to manage demand for residential property. Unlike BSD, ABSD Singapore rates depend heavily on the buyer's profile (Singapore Citizen, Permanent Resident, or Foreigner) and the number of residential properties currently owned.

Buyer Profile	1st Residential Property	2nd Residential Property	3rd & Subsequent
Singapore Citizen (SC)	0%	20%	30%
Permanent Resident (PR)	5%	30%	35%
Foreigners	60%	60%	60%
Entities / Trustees	65%	65%	65%

Candidates should note that for joint purchases involving different profiles, the highest applicable ABSD rate typically applies, unless specific remissions under Free Trade Agreements (FTAs) or matrimonial exemptions exist. For example, a Singapore Citizen and a Foreigner buying their first home together as a married couple may apply for a remission if they meet IRAS (opens in a new tab) criteria. Understanding these nuances is critical for the RES Exam Guide requirements, as Paper 2 frequently tests the application of ABSD on multi-owner scenarios.

Additional Buyer's Stamp Duty (ABSD) is a residential-only tax that varies by citizenship and property count, with current 2026 rates reaching 60% for foreigners and 65% for entities, serving as a primary tool for the Singapore government to maintain housing affordability and market stability.

Seller’s Stamp Duty (SSD) is designed to curb short-term property flipping. The rules for SSD property transactions depend strictly on the date of acquisition. According to current regulations, residential properties acquired on or after 4 July 2025 are subject to a 4-year holding period. If sold within this window, the rates are 16% (Year 1), 12% (Year 2), 8% (Year 3), and 4% (Year 4).

Properties acquired between 11 March 2017 and 3 July 2025 follow the older 3-year holding period schedule: 12% (Year 1), 8% (Year 2), and 4% (Year 3). For the RES exam, you must pay close attention to the acquisition date provided in the case study to determine which SSD regime applies. Industrial properties also attract SSD, but with a different 3-year schedule (15%, 10%, and 5%).

When studying the RES Course Guide, remember that SSD is calculated on the sale price or market value, whichever is higher. This tax is a significant consideration in the Planning Act (opens in a new tab) and property transaction lifecycle, as it directly impacts a seller's net proceeds.

Seller's Stamp Duty (SSD) applies to residential properties sold within a specific holding period, with a 4-year tiered rate starting at 16% for properties acquired from 4 July 2025 onwards, and a 3-year tiered rate starting at 12% for those acquired between 2017 and mid-2025.

Timing is everything in stamp duty compliance. In Singapore, stamp duty must be paid within 14 days of signing the Sale and Purchase Agreement (or Option to Purchase) if signed locally, or within 30 days if signed overseas. Failure to meet these deadlines results in significant penalties, which can be up to four times the amount of duty unpaid.

RES candidates must also understand remissions. For instance, a Singapore Citizen couple may be eligible for a refund of ABSD paid on their second residential property if they sell their first property within six months of the purchase of the second (for completed properties) or the TOP date (for uncompleted properties). This is a common scenario in HDB Resale Procedures and private market transitions.

For RES exam candidates, this topic falls under Taxation in Paper 2. You can practice questions on this in the Prepare app. The Estate Agents Act (Cap. 95A) (opens in a new tab) emphasizes the duty of a salesperson to provide accurate financial advice, which includes informing clients about these critical timelines and potential tax liabilities.

Stamp duty in Singapore must be settled within 14 days of document execution for local signings, and candidates must be familiar with ABSD remission rules for matrimonial HDB upgraders to pass the Paper 2 taxation competency unit effectively.

Q: Is the passing mark for the RES exam really 75%? No. The passing mark is 60 for each paper, subject to CEA review. You must pass both Paper 1 and Paper 2 to become a licensed salesperson.

Q: Where do I sit for the RES examination in 2026? The exam is a paper-based examination at Singapore Institute of Management Headquarters (SIM HQ), 461 Clementi Road. It is not a computer-based test.

Q: How often is the RES exam held? CEA holds the exam three times a year. The 2026 examination schedule published by CEA includes dates on 14-15 Mar, 18-19 Jul, and 31 Oct-1 Nov.

Q: What are the 2026 examination fees? The 2026 examination fees are S$512.30 for a full sitting (2 papers) and S$283.40 for a modular sitting (1 paper).

Q: Can I use a calculator for stamp duty questions in the exam? Yes, you are allowed to use a CEA-approved calculator. You will need it to calculate tiered BSD and ABSD amounts quickly during the 2 hour 30 minute duration of Paper 2.

The Singapore RES exam requires a passing score of 60 per paper and is conducted as a paper-based test at SIM HQ three times annually, with 2026 full-sitting fees set at S$512.30 including GST.

Taxation is one of the five core topics in Paper 2 of the RES exam. While Paper 1 focuses on legal foundations like the Land Titles Act (opens in a new tab), Paper 2 tests your practical ability to handle transactions. You should expect at least one case study in Section B to revolve around a buyer's financial calculation, incorporating BSD, ABSD, and potentially CPF usage limits.

To prepare effectively, start by memorizing the BSD tiers and the current ABSD table. Note that the CEA's revised RES syllabus applies to exams from 1 Jan 2027, but for 2026, the focus remains on current IRAS rates and HDB regulations.
