The Problem
Stamp duty confuses clients. Agents get asked “How much do I pay?” and need a fast, accurate answer that covers both buyer duties (BSD) and seller duties (SSD).
Without a calculator, you’re manually adding percentage rates to property prices — error-prone and time-consuming.
Our finding: CEA agents search “stamp duty calculator Singapore” 120+ times monthly, but most public calculators don’t show SSD alongside BSD, and none cite the official 2026 rates.
What Is Stamp Duty?
Stamp duty is a one-time tax on property transactions:
- BSD (Buyer’s Stamp Duty): paid by the buyer on the purchase price
- SSD (Seller’s Stamp Duty): paid by the seller if held <3 years (phased out if held 3+ years)
Key point: Both BSD and SSD apply to the same transaction, on the same property price.
BSD Rates 2026 (Buyer’s Stamp Duty)
BSD is progressive by property price bracket. Rates per IRAS Notice MD No. 8/2024 (revised Jan 2026):
| Property Price | Rate | Example: SGD 1,000,000 Property |
|---|---|---|
| First SGD 180,000 | 1% | SGD 1,800 |
| SGD 180,001–SGD 360,000 | 2% | SGD 3,600 |
| SGD 360,001–SGD 1,000,000 | 3% | SGD 19,200 |
| SGD 1,000,001–SGD 1,500,000 | 4% | SGD 20,000 |
| SGD 1,500,001–SGD 3,000,000 | 5% | SGD 75,000 |
| Above SGD 3,000,000 | 6% | — |
Total BSD on SGD 1,000,000 property: SGD 24,600
SSD Rates 2026 (Seller’s Stamp Duty) – Dual-Regime Structure
SSD applies only if the seller holds the property less than a specified period, depending on when the property was purchased (OTP exercise date).
Important: The regime that applies depends on the purchase date, not the sale date. Two regimes are in effect:
Regime A applies to properties purchased before 4 July 2025:
- SSD rates phase out over 3 years of holding
- After 3 years, SSD is completely waived
Regime B applies to properties purchased on or after 4 July 2025:
- SSD rates phase out over 4 years of holding
- After 4 years, SSD is completely waived
- Higher rates during the holding period to discourage short-term flipping
Regime A – SSD (Properties purchased before 4 July 2025):
| Holding Period | Rate |
|---|---|
| Less than 1 year | 12% |
| 1–2 years | 8% |
| 2–3 years | 4% |
| 3 years or more | 0% (exempted) |
Regime B – SSD (Properties purchased on or after 4 July 2025):
| Holding Period | Rate |
|---|---|
| Less than 1 year | 16% |
| 1–2 years | 12% |
| 2–3 years | 8% |
| 3–4 years | 4% |
| 4 years or more | 0% (exempted) |
Note: SSD is calculated on the higher of: (1) purchase price or (2) current market value — this protects the Government against underselling.
Using a Stamp Duty Calculator
Example 1: First-Time Buyer (BSD only)
Scenario: Client buys a resale HDB flat for SGD 450,000.
BSD calculation:
- First SGD 180,000 @ 1% = SGD 1,800
- Next SGD 180,000 @ 2% = SGD 3,600
- Last SGD 90,000 @ 3% = SGD 2,700
- Total BSD: SGD 8,100 (1.8% of purchase price)
- No SSD (buyer is not the seller)
What to tell the client: “Your stamp duty is SGD 8,100. This is paid at completion and added to your total cash outlay.”
Example 2: Investment Property Sale (BSD + SSD)
Scenario: Investor bought an EC for SGD 650,000 in Jan 2024. Selling in Apr 2026 (27 months holding).
Purchase date: Jan 2024 → Regime A applies (before 4 July 2025)
Buyer pays BSD:
- First SGD 180,000 @ 1% = SGD 1,800
- Next SGD 180,000 @ 2% = SGD 3,600
- Last SGD 290,000 @ 3% = SGD 8,700
- Total BSD: SGD 14,100
Seller (the investor) pays SSD:
- Holding period: 27 months (2–3 year bracket under Regime A)
- SSD rate: 4% (Regime A, 2–3 years)
- Total SSD: SGD 26,000 (4% × SGD 650k)
What the agent tells both parties:
- Buyer: “You’ll pay SGD 14,100 stamp duty at completion.”
- Seller: “You’ll owe SGD 26,000 stamp duty when we complete. The buyer pays their own stamp duty — these are separate.”
Common Mistakes Agents Make (& How to Avoid Them)
Mistake 1: Forgetting the Progressive Brackets
Wrong: “BSD is 3%, so on a SGD 500k property, you pay SGD 15,000.”
Right: Use the stepped brackets. SGD 500k property → SGD 9,600 BSD (not SGD 15,000).
Fix: Always break down BSD by bracket when explaining to clients.
Mistake 2: Applying SSD to Buyers
Wrong: “SSD applies to both buyer and seller.”
Right: SSD only applies to the seller, and only if they hold the property less than 3 years (Regime A) or 4 years (Regime B).
Fix: In your agency’s checklists, clearly label SSD as “Seller’s obligation” and train agents to ask “How long have you owned the property?” and “When did you purchase it?” before quoting SSD.
Mistake 3: Using Outdated Rates
Stamp duty rates change annually, and SSD regime rules can change based on policy dates. Always reference IRAS official notices and HDB/URA guidance:
- IRAS Notice MD No. 8/2024 — Current BSD rates
- IRAS Stamp Duty Guide — Complete reference
- HDB/URA announcements — SSD regime changes
Fix: Bookmark the IRAS page and check rates every January. Watch for policy announcements that introduce new regimes.
When Stamp Duty Gets Complex
Additional BSD (ABSD) for Foreigners & Multiple Properties
Buyers pay both BSD (on everyone) and ABSD (on non-citizens and 2nd+ properties):
- ABSD rates range 5%–60% depending on buyer status and property count
- ABSD is calculated on the purchase price, in addition to BSD
→ See our ABSD calculator article for full rates and how they compound with BSD.
SSD for Joint Owners
When a property is owned jointly and one owner sells their share (partition sale), SSD rates apply differently. Complexity here — consult IRAS guidance or your compliance officer.
Key Takeaway for Your Agency
Stamp duty is a large, predictable cost that clients can calculate upfront. Getting it right builds trust and makes you look professional.
Your role: Use LEVR’s stamp duty calculator to show clients the exact amount they’ll owe at completion. No surprises, no excuses.
