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

TL;DR: BSD applies to almost every property purchase, ABSD is an extra tax on certain residential buyers/profiles, and SSD is a tax on selling residential property within a minimum holding period. For the RES exam, you must know the rates, who pays, and how to calculate each duty.

Buyer’s Stamp Duty (BSD) is a progressive tax charged on the higher of the purchase price or market value of all properties in Singapore. For residential property, the current IRAS schedule (effective from 15 Feb 2023 and still in force in 2026) is: 1% on the first S$180,000; 2% on the next S$180,000; 3% on the next S$640,000; 4% on the next S$500,000; 5% on the next S$1.5 million; and 6% on the amount above S$3 million. This progressive structure underpins every BSD calculator you see online, and exam questions often test your ability to compute BSD step by step. BSD is payable on both residential and non‑residential properties.

Additional Buyer’s Stamp Duty (ABSD) is a cooling measure targeting buyers of residential properties based on their profile and property count. Current IRAS guidance shows that Singapore Citizens pay 0% ABSD on their first residential property, 20% on the second, and 30% on the third and subsequent properties; Permanent Residents pay 5%, 30% and 35% respectively; foreigners pay 60% on any residential property; while entities and trustees generally pay 65%. Housing developers face an additional 35% plus a non‑remittable 5% duty. These high rates mean ABSD is often the largest tax component of an investment property purchase.

Seller’s Stamp Duty (SSD) applies to residential properties sold within a prescribed holding period. For acquisitions on or after 4 Jul 2025, IRAS specifies a 4‑year holding period with SSD rates of 16% (up to 1 year), 12% (more than 1 year and up to 2 years), 8% (more than 2 and up to 3 years), and 4% (more than 3 and up to 4 years). For properties bought from 11 Mar 2017 to 3 Jul 2025, the older 3‑year schedule of 12%, 8% and 4% still applies. SSD is always calculated on the higher of price or market value.

For RES exam candidates, these duties fall under Taxation in Paper 2, alongside property tax and GST. Knowing who pays, when it’s due, and how to compute each duty is essential, because case-study MCQs often combine BSD, ABSD, SSD and financing scenarios in one problem. In the market, these rules directly affect affordability, investment returns and holding strategies for buyers and sellers.

“BSD is the baseline stamp duty every property buyer pays, calculated on a progressive scale on the higher of price or market value.” This is the core sentence you should memorise for both the exam and real‑life practice.

According to IRAS, for residential properties, BSD from 15 Feb 2023 onwards is charged as follows:

• First S$180,000: 1%
• Next S$180,000: 2%
• Next S$640,000: 3%
• Next S$500,000: 4%
• Next S$1,500,000: 5%
• Remaining amount above S$3,000,000: 6%

The same page notes that BSD is always based on the higher of purchase price or market value, not the lower number. For non‑residential property, the top marginal rate is 5%, but the exam will usually specify if the property is residential or non‑residential. Candidates are expected to apply these bands accurately and be able to compute BSD to the nearest dollar, as IRAS rounds duty down to the nearest S$1.

Example (RES‑style): A buyer purchases a residential condo at S$2,200,000. Assuming the price reflects market value, BSD is:

• First S$180,000 @1% = S$1,800
• Next S$180,000 @2% = S$3,600
• Next S$640,000 @3% = S$19,200
• Next S$500,000 @4% = S$20,000
• Remaining S$700,000 (from S$1.5m to S$2.2m) @5% = S$35,000 Total BSD = S$79,600.

In practice, many buyers rely on a BSD calculator, but in the RES exam you must understand how each tier is applied. Expect MCQs that:

• Ask for the exact BSD amount for a given price
• Compare two properties and ask which incurs higher BSD and by how much
• Combine BSD with ABSD and test total upfront cash required, especially in Paper 2 case studies

For RES exam candidates, BSD and other stamp duties sit under Taxation in Paper 2. You can practise detailed BSD calculation questions in the Prepare app, especially alongside other tax topics like property tax and GST. A solid grasp of the BSD rate bands and calculation steps is a reliable way to secure marks in Paper 2.

“ABSD is an extra stamp duty on residential property, based on the buyer’s residency status and the number of properties owned.” Remember this definition — it often appears almost verbatim in RES MCQs and case studies.

IRAS specifies ABSD rates by profile and property count. Current guidance (updated after the latest rounds of cooling measures) shows broadly:

• Singapore Citizens: 0% on 1st residential property, 20% on 2nd, 30% on 3rd and subsequent properties
• Permanent Residents (PRs): 5% on 1st, 30% on 2nd, 35% on 3rd and subsequent properties
• Foreigners: 60% on any residential property
• Entities & Trustees: typically 65% on any residential property
• Housing Developers: 35% ABSD plus a non‑remittable 5% (total 40%), with additional conditions

ABSD is charged on the higher of the purchase price or market value of the residential portion, similar to BSD. Where the buyer is a trustee, IRAS applies a specific ABSD (Trust) rate of 65% on any conveyance of residential property to be held in trust. This is a frequent exam trap: candidates must identify when a purchase is made by or for a trustee, not just the beneficial owner.

Example: A Singapore Citizen already owns one condo and buys a second residential unit at S$1.8 million (market value S$1.9 million). ABSD is based on S$1.9 million. At 20%, ABSD = S$380,000. BSD is then computed separately on S$1.9 million using the BSD bands. Together, BSD plus ABSD can significantly increase the cash and CPF required for completion.

In Paper 2, exam questions commonly test:

• How many properties a buyer is treated as owning (including partial shares)
• Distinguishing residential vs non‑residential property for ABSD
• ABSD on joint purchases (e.g., SC + PR spouses, or with a company)
• ABSD (Trust) when buying under a family trust

For both the public and RES candidates, ABSD directly shapes investment decisions, upgrading plans, and structuring of joint purchases. For RES exam candidates, ABSD sits squarely under Taxation in Paper 2, and you can practise corresponding calculations under the Taxation topic in the Prepare app and on our Taxation page.

“SSD is a tax on selling residential property within a minimum holding period, with higher rates for shorter holding periods.” Knowing which schedule applies by acquisition date is critical both for the exam and for advising clients.

IRAS distinguishes SSD rates based on when the residential property was acquired. For acquisitions on or after 4 Jul 2025, SSD applies over a 4‑year holding period:

• Sold within 1 year: 16% of the higher of price or market value
• More than 1 year and up to 2 years: 12%
• More than 2 years and up to 3 years: 8%
• More than 3 years and up to 4 years: 4%
• More than 4 years: No SSD

For properties acquired between 11 Mar 2017 and 3 Jul 2025 (both dates inclusive), the older 3‑year SSD schedule continues to apply:

• Sold within 1 year: 12%
• More than 1 year and up to 2 years: 8%
• More than 2 years and up to 3 years: 4%
• More than 3 years: No SSD

A key exam point is that SSD applies only to residential properties and is calculated on the higher of selling price or market value at the time of disposal. Candidates must pay attention to the date of purchase and the date of sale to determine the correct rate.

Example: A unit bought on 10 Aug 2025 for S$1,000,000 is sold on 9 Aug 2027 (holding period just under 2 years). The applicable schedule is the new 4‑year regime. SSD rate is 12% (more than 1 year, up to 2 years). If the sale price is S$1,100,000 (and market value is the same), SSD = S$132,000.

For exam questions, expect SSD to be tested alongside capital gains assumptions (Singapore generally has no capital gains tax) and property flipping scenarios. For real‑world clients, SSD can materially erode profits if they sell too early, so salespersons must be able to explain the holding period and cost implications clearly.

“Think of BSD as the standard entry tax, ABSD as a cooling‑measure surcharge on certain residential buyers, and SSD as an exit tax on short‑term sales.” Having this mental model helps you quickly categorise any stamp duty scenario in exams and practice.

Below is a compact comparison table you can memorise or adapt into your own notes:

Feature	BSD	ABSD	SSD
Main purpose	Baseline stamp duty on buying or acquiring property	Additional cooling measure on buying residential property	Tax on selling/disposing residential property within holding period
Applies to	All property (residential and non‑residential)	Residential property only	Residential property only
Key basis	Higher of purchase price or market value	Higher of purchase price or market value	Higher of selling price or market value
Who pays	Buyer / acquirer	Buyer / acquirer (by profile and property count)	Seller / disposer
Rate structure	Progressive: 1% to 6% for residential	Flat rate by profile: 0%–65%+, developers additional 5% non‑remittable	Flat % based on holding period (up to 16%)
Main variables	Property type and price	Residency, number of properties, entity/trust	Acquisition date and holding period

In Paper 2 Taxation, exam questions often combine all three:

• Compute BSD for a purchase
• Add ABSD based on buyer’s profile and existing properties
• Consider SSD if the client has another property to sell

Remember that these duties are grounded in Singapore’s statutory framework, including the Stamp Duties Act, and must be read together with broader real‑estate laws like the Land Titles Act and planning controls under the Planning Act. For HDB transactions, you should also be familiar with HDB Resale Procedures, as they determine timelines and documentation that interact with stamp duty payment deadlines.

For RES exam candidates, this topic is part of Taxation in Paper 2, which sits alongside other practical topics like HDB, CPF, marketing and sale procedures. If you are planning your study roadmap, our RES Exam Guide and RES Course Guide can help you structure revision to cover stamp duties systematically before your exam window.

“Many RES candidates struggle not with the concepts, but with applying stamp duty rules under time pressure.” This Q&A addresses the most common practical and exam‑oriented questions.

Q1: How important are ABSD, BSD and SSD for the RES exam?
Stamp duties fall under the Taxation topic in Paper 2, which covers stamp duty, property tax, GST, ABSD and SSD. Because Paper 2 uses both standard MCQs and case‑study MCQs, stamp duty scenarios are a reliable source of marks, and they frequently appear together with HDB, CPF and financing questions.

Q2: Will the RES exam test the latest ABSD, BSD and SSD rates?
The Council for Estate Agencies (CEA) expects candidates to be familiar with current Singapore laws and IRAS guidelines. Where there are recent changes, such as the new 4‑year SSD regime from 4 Jul 2025, exam questions may specify the acquisition date. For safety, always use the latest official rates in your revision.

Q3: Is it enough to memorise the tables, or do I need to practise calculations?
You must be able to calculate BSD, ABSD and SSD quickly for different property prices and profiles. In the Computer‑Based Test (CBT) format, each paper lasts 2 hours 30 minutes, with 60 MCQs and 20 case‑study MCQs, so speed and accuracy are critical.[RES exam context] Practising with realistic numbers (e.g., S$1m–S$2m properties) is more effective than rote memorisation alone.

Q4: How do stamp duties interact with CPF and cash requirements?
Stamp duties are usually payable within a short period after exercise of the Option to Purchase or completion of the sale, and can often be paid using CPF savings subject to CPF Board rules. In the exam, you may see questions that require you to compute total cash plus CPF needed, including BSD and ABSD, and to assess affordability for the client.

Q5: How much does it cost to sit the RES exam, and does this include stamp duty topics?
For 2026, the examination fee is S$512.30 for a full sitting (both papers) and S$283.40 for a modular sitting (one paper), as published by CEA’s appointed administrator NTUC LearningHub.[RES exam context] Both Paper 1 and Paper 2 are required to qualify as a salesperson, and Taxation (including stamp duties) is part of Paper 2’s syllabus. If you are budgeting for your RES journey, you can review our Pricing page for course and practice options.

For the general public, understanding stamp duties helps you plan when to buy, sell or hold property, and what costs to expect. For RES exam candidates, these same rules are tested in applied scenarios, so combining concept understanding with timed practice is the best preparation strategy.

“For the RES exam, you must be able to replicate what a stamp duty calculator does — manually, quickly and accurately.” Treat each BSD, ABSD and SSD question as a step‑by‑step computation problem, not a memory test.

Here are practical strategies:

1. Memorise BSD bands with anchor numbers.
   Anchor the residential BSD thresholds at S$180k, S$360k, S$1m, S$1.5m and S$3m, corresponding to 1%, 2%, 3%, 4%, 5% and 6% respectively. Practise writing out the bands quickly on scrap paper at the start of the CBT session. This reduces mental load when doing multiple questions.

2. Use a systematic layout for calculations.
   For each problem, write:

• Price / market value (pick the higher as your base)
• Break down into BSD bands
• Apply ABSD rate next (if residential and applicable)
• Consider SSD separately if a sale within the holding period This mirrors how most BSD calculator tools work, but in the exam you’re your own calculator.

3. Pay attention to acquisition dates for SSD.
   Always determine if the property was acquired before or after 4 Jul 2025, then apply the correct 3‑year or 4‑year SSD schedule. Many case‑study MCQs are designed to test whether you notice the date and pick the correct rate.

4. Cross‑link to other topics.
   Stamp duty questions frequently link to:

• Estate Agents Act (Cap. 95A) – duty of care and disclosure when advising clients on costs
• Land Titles Act and Planning Act – property type, zoning, and whether a property is treated as residential
• HDB Resale Procedures – timing of HDB approvals and when stamp duties are paid Understanding these linkages can help you eliminate wrong options in integrated case studies.

5. Simulate exam conditions.
   The RES exam is a Computer‑Based Test with multiple sessions scheduled throughout the year, including 14–15 Mar, 18–19 Jul, and 31 Oct–1 Nov 2026.[RES exam context] Aim to complete each paper’s 80 questions (60 MCQs + 20 case‑study MCQs) within 2 hours 30 minutes, targeting a score of at least 60 marks per paper, which is the current passing mark (subject to CEA review).[RES exam context]

For RES exam candidates, ABSD, BSD, SSD and other stamp duties belong to Taxation in Paper 2. You can practise stamp duty, property tax, GST and related questions across all 13 RES topics using the Prepare app’s question bank and Free RES Practice. The app offers realistic, exam‑style scenarios that reinforce the exact skills you need: interpreting Singapore laws correctly, applying IRAS rules, and computing duties with confidence.
