ABSD Rates and Exemptions in Taxation: RES Exam Deep Dive

TL;DR: Additional Buyer’s Stamp Duty (ABSD) is a wealth tax imposed on residential property purchases in Singapore, calculated based on the buyer's profile and the number of residential properties owned. As of 2025, rates range from 0% for a Singapore Citizen's first home to 65% for entities and trustees.

The legal basis for ABSD is found within the Stamp Duties Act, which empowers the Inland Revenue Authority of Singapore (IRAS) to collect duties on instruments relating to immovable property. For the RES exam, it is vital to distinguish between Basic Buyer’s Stamp Duty (BSD) and ABSD. While BSD applies to all property types (residential and non-residential), ABSD is strictly a residential tax measure.

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

For RES exam candidates, this topic falls under Taxation in Paper 2. You can practice questions on this in the Prepare app. Understanding these rates is essential because, as of 2026, there are over 33,000 registered property agents in Singapore (source: CEA Annual Report) who must accurately advise clients on these high-stakes financial obligations. ABSD rates Singapore 2025 require Singapore Citizens to pay 20% on their second residential property and 30% on subsequent purchases, while Foreigners face a flat 60% rate on all residential acquisitions to maintain housing affordability.

A common area of confusion in the RES exam involves the distinction between an 'exemption' and a 'remission.' A remission typically involves paying the tax first and claiming it back later, provided specific conditions are met. The most frequent scenario is the ABSD remission for married couples.

Under IRAS guidelines, a married couple (including at least one Singapore Citizen) can claim a refund on the ABSD paid for their second residential property if they sell their first property within six months of:

1. The date of purchase of the second property (for completed properties), or
2. The TOP/CSC date (for uncompleted properties), whichever is earlier.

Candidates must remember that the couple must remain married at the point of application and must not have purchased any other residential property since the acquisition of the second property. This nuance is frequently tested in Paper 2. For more details on related financial topics, see our CPF and Finance Guide. ABSD exemptions remission rules allow married couples with at least one Singapore Citizen spouse to claim a full refund of the ABSD paid on their second home if they dispose of their first property within the statutory six-month window.

One of the most 'tricky' edge cases in the RES exam involves Foreigners who are treated as Singapore Citizens for ABSD purposes. Under various Free Trade Agreements (FTAs), nationals and Permanent Residents of specific countries are eligible for the same ABSD treatment as Singapore Citizens.

These countries include:

• Iceland
• Liechtenstein
• Norway
• Switzerland
• United States of America (Nationals only)

In an exam scenario, if a US National is buying their first residential property in Singapore, the ABSD rate is 0%, not 60%. This is a critical distinction that separates high-scoring candidates from the rest. This topic links directly to the Singapore Property Market Context and legal foundations. According to the CEA's 2025 annual report, the RES exam pass rate remains challenging at approximately 45%, largely due to these technical nuances. Nationals of the USA, Iceland, Liechtenstein, Norway, and Switzerland enjoy ABSD treatment equivalent to Singapore Citizens, meaning they pay 0% ABSD on their first residential property purchase in Singapore under prevailing Free Trade Agreements.

To prevent the use of trusts to circumvent ABSD, the government introduced a standardized ABSD (Trust) rate. Any transfer of residential property into a living trust is subject to an ABSD rate of 65% as of 2025. This is payable even if there is no identifiable beneficial owner at the time of the transfer.

However, a Refund of ABSD (Trust) may be applied for if:

1. The beneficial owners are identifiable individuals.
2. Beneficial ownership has vested in these individuals at the time of transfer.
3. The trust is irrevocable.

In the RES exam, you may be asked to calculate the total stamp duty for a trustee purchase. You must apply the 65% rate first before considering if a refund is possible based on the beneficiary's profile. This connects to Land Law and the Estate Agents Act. The ABSD (Trust) rate of 65% is applied upfront to all residential property transfers into a trust, though a remission may be sought if the beneficial owners are clearly identified and the trust is legally irrevocable.

Q: Does ABSD apply to commercial or industrial properties? A: No. ABSD only applies to residential properties. If a property is zoned 'Commercial' under the Planning Act, no ABSD is payable. However, 'Commercial and Residential' mixed-use sites are subject to ABSD on the residential component.

Q: How is ABSD calculated for joint purchasers with different profiles? A: The highest applicable rate is used. If an SC (1st property) buys with a Foreigner, the entire purchase is taxed at the Foreigner rate of 60%.

Q: What is the passing score for the RES exam in 2026? A: The passing score is 75% (60 out of 80 questions) across two papers. The registration fee is S$408.55 (inclusive of GST) in 2026.

Q: Are HDB flats exempt from ABSD? A: No. While HDB buyers don't usually pay ABSD on their first flat, they must pay ABSD if they already own a private property. Conversely, HDB owners buying private property must pay ABSD upfront and may claim a remission later if they sell the flat. For RES exam candidates, this topic falls under Taxation in Paper 2. You can practice questions on this in the Prepare app. ABSD RES exam questions frequently test the 'highest rate' rule for joint purchasers, where the profile with the highest tax liability determines the total duty payable for the entire property transaction.

IRAS has recently intensified audits on '99-to-1' property holding arrangements. This occurs when a buyer with a lower ABSD rate (e.g., a first-timer) buys 99% of a property, and a buyer with a higher rate (e.g., a second-timer) buys 1%. Shortly after, the 1% is transferred to the second buyer to facilitate financing or future planning.

Section 33A of the Stamp Duties Act allows the Commissioner of Stamp Duties to disregard any arrangement that is carried out with the primary purpose of tax avoidance. For RES candidates, it is vital to understand that as a salesperson, advising a client to enter such an arrangement could lead to professional misconduct under the Estate Agents Act (Cap. 95A).

Feature	Mitigation (Legal)	Avoidance (Illegal/Audit Risk)
Intent	Genuine home ownership/investment	Artificial structuring to reduce tax
Example	Selling 1st home to buy 2nd (Remission)	99-to-1 share splitting to bypass ABSD
Consequence	Tax benefits within law	Surcharge of 50% + potential penalties

Internal Link: Common Exam Mistakes. IRAS actively monitors property transactions for tax avoidance schemes like the 99-to-1 arrangement, using Section 33A of the Stamp Duties Act to recover unpaid ABSD and impose a 50% surcharge on transactions deemed to have no commercial substance other than tax reduction.

ABSD does not exist in a vacuum; it is deeply intertwined with other Paper 2 topics such as HDB Resale Procedures and Sale of Properties. For instance, when a client buys a New Launch (Developer Sale), the ABSD is payable within 14 days of exercising the Option to Purchase (OTP). In contrast, for HDB resale, the timeline is tied to the completion of the resale application.

Understanding ABSD is also crucial for Real Estate Marketing and financial calculations. An agent must be able to calculate the 'Total Acquisition Cost,' which includes BSD, ABSD, and legal fees, to ensure a client's CPF and cash reserves are sufficient.

As you prepare for your 2.5-hour CBT (Computer-Based Test), remember that Taxation (Paper 2, 116 practice questions) is often the section where candidates lose marks due to calculation errors. The Prepare app offers comprehensive practice questions across all 13 RES exam topics, including detailed ABSD scenarios, to help you reach that 75% passing threshold. Mastery of ABSD rates and exemptions is a core competency for the RES exam, as it directly impacts a salesperson's ability to provide accurate financial advice and ensure compliance with Singapore's stringent property taxation laws.
