ABSD Calculation: Every Buyer Profile Scenario Explained

Additional Buyer’s Stamp Duty (ABSD) is calculated as ABSD rate × higher of purchase price or valuation, and layered on top of Buyer’s Stamp Duty (BSD). As of 2026, the post‑27 Apr 2023 IRAS schedule still applies for residential property purchases.

2026 ABSD rates by buyer profile (residential property)

Buyer profile	1st residential property	2nd residential property	3rd & subsequent residential property
Singapore Citizen (SC)	0%	20%	30%
Singapore Permanent Resident (SPR / PR)	5%	30%	35%
Foreigner (non‑FTA)	60%	60%	60%
Entity (company / trust)	65%	65%	65%

For RES exam calculation questions, always: (1) identify buyer profile, (2) count residential properties correctly, (3) apply the correct ABSD tier from IRAS’ schedule, and (4) compute BSD and ABSD on the same taxable amount before summing. This four‑step chain is what exam setters test under Taxation in Paper 2.

For RES exam candidates, ABSD falls under Taxation (Paper 2) alongside BSD, SSD, property tax and GST. You can explore the broader syllabus structure in the Taxation overview and practice exam‑style ABSD questions in the Prepare app. This article focuses specifically on step‑by‑step ABSD calculation walkthroughs for every buyer profile.

2026 ABSD rates Singapore follow IRAS’ post‑27 Apr 2023 cooling measures: 0–30% for citizens, 5–35% for PRs, 60% for foreigners, and 65% for entities, always computed on the higher of price or valuation and added to BSD for total stamp duty.

“For Singapore Citizens, ABSD is 0% on the 1st residential property, 20% on the 2nd, and 30% on the 3rd and subsequent properties as at 2026.”

Formula (SC):

• 1st property: ABSD = 0%
• 2nd property: ABSD = 20% × taxable amount
• 3rd+ property: ABSD = 30% × taxable amount

Taxable amount = higher of purchase price or market valuation. BSD is always computed separately using IRAS’ BSD tiers, then added to ABSD for total stamp duty.

Worked example 1 – SC buying 1st property (no ABSD)
A Singapore Citizen buys a $1.2M condo as their first residential property.

1. Taxable amount = $1,200,000 (assume valuation equals price).
2. ABSD rate (1st property, SC) = 0%.
3. ABSD = 0% × $1,200,000 = $0.
4. BSD still applies on $1,200,000 using the standard BSD tiers.
5. Total stamp duty payable = BSD only, ABSD = $0.

This mirrors typical RES MCQs where the trap is to wrongly apply 20% ABSD on an SC’s first residential purchase. Remember: SC first property → ABSD 0%.

Worked example 2 – SC buying 2nd property
A Singapore Citizen already owns one private condo. They buy a $1.2M second condo.

1. Confirm property count: existing 1 + new 1 = 2nd residential property.
2. Taxable amount = higher of price/valuation. Assume $1,200,000.
3. ABSD rate (SC, 2nd property) = 20%.
4. ABSD = 20% × $1,200,000 = $240,000.
5. Compute BSD on $1,200,000 using the BSD tiers, e.g. IRAS’ standard residential BSD rates.
6. Total stamp duty = BSD + $240,000.

Exam trap: candidates sometimes apply 30% instead of 20% for an SC’s 2nd property. Always cross‑check: SC 2nd property → 20%; SC 3rd+ → 30%.

For RES exam candidates, SC ABSD scenarios frequently appear in case‑study MCQs under Taxation (Paper 2). You can drill similar step‑by‑step questions via Free RES Practice and the Prepare app for stronger calculation speed.

“For Singapore Permanent Residents (PRs) in 2026, ABSD is 5% on the 1st residential property, 30% on the 2nd, and 35% on the 3rd and subsequent residential properties according to IRAS’ current schedule.”

Formula (PR):

• 1st property: ABSD = 5% × taxable amount
• 2nd property: ABSD = 30% × taxable amount
• 3rd+ property: ABSD = 35% × taxable amount

Again, the taxable amount is the higher of price or valuation, and BSD must be calculated separately and added.

Worked example 3 – PR buying first residential property
A Singapore PR with no existing property buys a $900,000 resale HDB flat.

1. Check profile: PR, first residential property.
2. Taxable amount = $900,000 (assume valuation = price).
3. ABSD rate (PR, 1st property) = 5%.
4. ABSD = 5% × $900,000 = $45,000.
5. Compute BSD on $900,000 using IRAS BSD tiers.
6. Total stamp duty = BSD + $45,000.

This directly answers the common search, “IRAS ABSD rates Singapore permanent resident first residential property 2026” – PR first property → 5% ABSD on price/valuation + BSD.

Worked example 4 – PR upgrading to 2nd property (retains 1st)
A PR owns a $600,000 HDB and buys a $1.4M condo without selling the HDB.

1. Property count at purchase: 1 existing + 1 new = 2nd residential property.
2. Taxable amount for ABSD/BSD = higher of price/valuation; assume $1,400,000.
3. ABSD rate (PR, 2nd property) = 30%.
4. ABSD = 30% × $1,400,000 = $420,000.
5. Compute BSD on $1,400,000.
6. Total stamp duty = BSD + $420,000.

RES exam trap: many candidates mistakenly apply the 5% “PR first property” rate because the condo is their first private property. ABSD is based on total residential count, not whether it is the first private home. PR with one existing HDB buying a condo → 2nd property ABSD 30%.

“In 2026, foreign individuals without FTA relief pay 60% ABSD on any residential purchase, while entities and trusts generally pay 65% ABSD regardless of property count.”

Formula (foreigner / entity):

• Foreigner (non‑FTA): ABSD = 60% × taxable amount (any property)
• Entity / company / trust: ABSD = 65% × taxable amount (any property)
• Housing developers: IRAS applies special developer ABSD, often 40% (35% remittable + 5% non‑remittable) under current rules.

Worked example 5 – foreigner buying a $2M condo
A foreign individual (no FTA pact) buys their first Singapore condo at $2,000,000.

1. Profile: foreigner, residential, no remission.
2. Taxable amount = higher of price/valuation; assume $2,000,000.
3. ABSD rate = 60% (1st, 2nd or 3rd – same rate).
4. ABSD = 60% × $2,000,000 = $1,200,000.
5. Compute BSD on $2,000,000 using residential BSD tiers.
6. Total stamp duty = BSD + $1,200,000.

Exam trap: some questions hide the foreigner profile in a long vignette. Always identify citizenship first; if non‑SC/PR and no FTA remission, apply flat 60% ABSD.

Worked example 6 – company buying $3M residential property
A Singapore‑incorporated company buys a $3,000,000 residential building for investment.

1. Profile: entity (company), residential use.
2. Taxable amount = higher of price/valuation; assume $3,000,000.
3. ABSD rate (entity) = 65% in 2026, per IRAS schedule.
4. ABSD = 65% × $3,000,000 = $1,950,000.
5. Compute BSD on $3,000,000.
6. Total stamp duty = BSD + $1,950,000.

Housing developers face separate ABSD rules (often quoted as an effective 40% rate with a non‑remittable 5%), but such scenarios are rarely tested in depth at RES level. The more common exam focus is the 60% foreigner and 65% entity ABSD calculation, added to BSD.

For RES exam candidates, foreigner and entity ABSD questions typically appear in Paper 2 case‑studies under Taxation. You can explore related cooling measures like LTV and TDSR via official MAS releases and reinforce calculations using the Homejourney stamp duty calculator mentioned in their ABSD guide.

“Every RES exam stamp duty question expects you to compute BSD + ABSD on the same taxable amount. Many candidates lose marks by calculating ABSD only or using the wrong base (price vs valuation).”

General calculation chain (2026):

1. Identify property type (residential vs non‑residential).
2. Identify buyer profile (SC, PR, foreigner, entity).
3. Count current residential properties at the time of purchase.
4. Determine taxable amount = higher of purchase price or market valuation.
5. Compute BSD using IRAS BSD tiers (not covered in full here).
6. Apply relevant ABSD rate from the 2026 schedule.
7. Total stamp duty payable = BSD + ABSD.

Worked example 7 – SC buying 3rd property with higher valuation
A Singapore Citizen owns two condos. They buy a third condo:

• Purchase price: $1,800,000
• Bank valuation: $1,900,000

Step‑by‑step:

1. Profile: SC; property count after purchase = 3 → 3rd property ABSD 30%.
2. Taxable amount = higher of $1,800,000 (price) and $1,900,000 (valuation) = $1,900,000.
3. BSD: apply IRAS BSD tiers on $1,900,000 (e.g. progressive rates for residential property).
4. ABSD: 30% × $1,900,000 = $570,000.
5. Total stamp duty = BSD on $1,900,000 + $570,000.

Common RES exam traps in ABSD calculation questions:

• Using purchase price instead of higher of price/valuation.
• Forgetting to add BSD and ABSD.
• Miscounting properties (e.g. ignoring jointly‑owned units or recently TOP‑ed units).
• Applying SC rates to PRs or vice versa.

The safest exam strategy is to write out the steps explicitly: profile → property count → ABSD tier → taxable amount → BSD → ABSD → total. In 40‑mark case‑study MCQs, this written chain helps you avoid mis‑clicks and trap answers.

For a wider Taxation overview, including SSD and property tax rules, refer to the Taxation page and official IRAS stamp duty guidance. For exam structure (2 papers, 60+20 MCQs, 2h30 each, passing mark 60 per paper), the RES Exam Guide provides detailed context aligned with CEA’s latest information.

“To pass ABSD questions quickly, memorise the 2026 ABSD buyer profile table and then plug the correct rate into your calculation chain.”

ABSD rates 2026 by buyer profile and property count

Buyer profile	1st residential property ABSD	2nd residential property ABSD	3rd+ residential property ABSD	Key exam notes
Singapore Citizen (SC)	0%	20%	30%	Only 2nd and 3rd+ properties attract ABSD; count all residential units, including joint‑ownership.
Singapore PR (SPR)	5%	30%	35%	PR first property still has ABSD (5%); common exam trap vs SC 0%.
Foreigner (individual)	60%	60%	60%	Flat 60% for all residential properties if no FTA remission; check nationality carefully.
Entity / Company / Trust	65%	65%	65%	Flat 65% on residential acquisitions; housing developers have special ABSD rules (often 40% with non‑remittable portion).

This table summarises the current IRAS ABSD schedule (post‑27 Apr 2023 measures, still in force in 2026) that you must apply in exam calculations.

Related RES exam context
The RES Examination, administered by the Council for Estate Agencies (CEA) via NTUC LearningHub, has 2 papers. Each paper has 60 MCQs in Section A and 20 case‑study MCQs in Section B, lasts 2 hours 30 minutes, and currently requires a passing mark of 60 per paper, subject to CEA review. The 2026 exam fees are S$512.30 for a full sitting and S$283.40 for a modular sitting, according to recent CEA and LearningHub schedules.

ABSD falls under Paper 2 – Taxation together with BSD, SSD, property tax and GST. For RES candidates, practice usually spans about 2–4 months of study, with exam windows such as 14–15 Mar, 18–19 Jul, and 31 Oct–1 Nov in 2026, based on CEA’s published schedule. These dates guide your revision plan and mock‑calculation practice.

For deeper legislation context, ABSD is part of Singapore’s property cooling measures, interacting with laws like the Estate Agents Act (Cap. 95A), the Land Titles Act, and policies on residential investment. Study those in your RES course materials and reinforce the calculation side using step‑by‑step examples such as those in this article.

Q1. How do I calculate ABSD for any buyer profile in Singapore?
A: Use this universal formula: ABSD = applicable ABSD rate × higher of purchase price or valuation. Identify the buyer profile (SC, PR, foreigner, entity), count existing residential properties, pick the correct 2026 rate tier from IRAS’ ABSD table, then add BSD to get total stamp duty.

Q2. What is the ABSD rate for a Singapore PR buying their first residential property in 2026?
A: The ABSD rate for a PR’s first residential property is 5%, computed on the higher of price or valuation, plus BSD. Example: PR buying a $900,000 first home pays ABSD = 5% × $900,000 = $45,000, on top of BSD.

Q3. Do Singapore Citizens pay ABSD on their first residential property?
A: No. In 2026, Singapore Citizens pay 0% ABSD on the 1st residential property, 20% on the 2nd, and 30% on the 3rd and subsequent properties. For exam questions, confirm that the buyer has no other residential unit (including joint‑ownership) before applying 0%.

Q4. What is the ABSD rate for foreigners and companies?
A: Foreign individuals without FTA relief pay a flat 60% ABSD on every residential purchase, while companies and trusts pay 65% ABSD. Housing developers are subject to separate ABSD rules (often 40% with a non‑remittable component) under IRAS’ cooling measures.

Q5. Are BSD and ABSD both tested in the RES exam? Which paper covers them?
A: Yes. BSD, ABSD, SSD, property tax and GST are core parts of the Taxation topic in RES Paper 2, which covers practical transaction issues. Questions appear in standard MCQs and case‑study MCQs, often requiring full calculation chains rather than just final answers.

Q6. How can I practice ABSD calculation questions effectively?
A: Combine: (1) official IRAS examples, (2) a stamp duty calculator like Homejourney’s for self‑checking, and (3) exam‑style MCQs. On howtopassres.com you can use Free RES Practice, our Pricing page for full access, and the Prepare app for ABSD calculations across realistic RES scenarios.

Whether you are a property buyer or an exam candidate, mastering ABSD calculation means memorising the current 2026 rates and then drilling the step‑by‑step process. The Prepare app supports this with practice questions across all 13 RES topics, including detailed Taxation case‑studies that mirror CEA’s computer‑based test format.
