BSD Singapore 2026 — Buyer Stamp Duty Calculator, Rates and Complete Guide
Purchasing property in Singapore involves several statutory costs, with Buyer Stamp Duty (BSD) representing one of the most significant upfront expenses for every transaction. As the property market evolves into 2026, understanding how BSD is calculated, when it must be paid, and how it interacts with additional buyer taxes is essential for financial planning. This comprehensive guide breaks down the 2026 BSD framework, provides exact rate tables, illustrates real-world calculations, and outlines the official IRAS payment procedures so you can complete your property purchase with full compliance and confidence.
BSD is calculated on a progressive marginal basis across six price tiers. For a standard $1 million residential property, BSD equals $24,600. For a $2 million home, it rises to $69,600, and for a $3 million property, BSD amounts to $114,600. All buyers, regardless of citizenship or residency status, must pay BSD. It is payable within 14 days of signing the Sale & Purchase Agreement (for resale) or exercising the Option to Purchase (for new launches). Payment is completed exclusively through the IRAS e-Stamping portal.

BSD Rate Table 2026
The 2026 Buyer Stamp Duty framework operates on a marginal taxation structure, meaning each portion of the property price is taxed at its corresponding tier rate rather than applying a flat percentage to the entire purchase price. This progressive model ensures that entry-level buyers pay proportionally less than premium-market purchasers. Below is the official BSD rate schedule for residential property acquisitions in Singapore for 2026:
| Property Value Tier | Marginal Rate | Cumulative BSD at Tier Cap |
|---|---|---|
| First $180,000 | 1% | $1,800 |
| $180,001 to $360,000 | 2% | $5,400 |
| $360,001 to $1,000,000 | 3% | $24,600 |
| $1,000,001 to $1,500,000 | 4% | $44,600 |
| $1,500,001 to $3,000,000 | 5% | $114,600 |
| Above $3,000,000 | 6% | Scales progressively |
This tiered structure means that if you purchase a property priced at $1.2 million, only the portion between $1 million and $1.2 million is taxed at 4%, while all lower brackets retain their respective lower rates. This approach prevents sudden tax cliffs and aligns duty obligations with the buyer’s financial capacity.

BSD Calculator — 5 Worked Examples by Property Price
Understanding marginal taxation is best achieved through practical examples. Below are five worked calculations demonstrating exactly how BSD is computed across different property valuations in 2026. Each example breaks down the tier-by-tier accumulation to show why the final figure differs from a simple flat-rate multiplication.
Example 1: Entry-Level Apartment ($650,000)
First $180,000 at 1% = $1,800
Next $180,000 at 2% = $3,600
Remaining $290,000 at 3% = $8,700
Total BSD = $14,100
Example 2: Standard 3-Room Resale Flat ($1,000,000)
First $180,000 at 1% = $1,800
$180,001–$360,000 at 2% = $3,600
$360,001–$1,000,000 at 3% = $19,200
Total BSD = $24,600
Example 3: Mid-Range Executive Condominium ($1,350,000)
Cumulative BSD up to $1M = $24,600
$1,000,001–$1,350,000 at 4% = $14,000
Total BSD = $38,600
Example 4: Prime District Private Condo ($2,000,000)
Cumulative BSD up to $1.5M = $44,600
$1,500,001–$2,000,000 at 5% = $25,000
Total BSD = $69,600
Example 5: Luxury Landed Property ($3,000,000)
Cumulative BSD up to $1.5M = $44,600
$1,500,001–$3,000,000 at 5% = $70,000
Total BSD = $114,600
These calculations reflect the exact statutory framework mandated by the Inland Revenue Authority of Singapore. Buyers should always verify the final dutiable value with their conveyancing lawyer, as IRAS may adjust the valuation slightly based on recent comparable transactions in the immediate vicinity.
When Must You Pay BSD? — Deadlines and Penalties
Timing is critical when fulfilling your stamp duty obligations. The 14-day payment window begins from the date of the relevant legal document execution. For resale transactions, the countdown starts the day after you sign the Sale & Purchase Agreement. For new launch developments, it commences the day you exercise your Option to Purchase. Missing this statutory deadline triggers substantial penalties that compound daily, making prompt payment a financial necessity rather than a mere administrative task.
If BSD is paid within 14 days, there are no penalties. Between 15 and 30 days late, IRAS imposes a penalty of $10 or the amount of duty unpaid, whichever is greater. Once payment exceeds 30 days, the penalty escalates to four times the unpaid duty amount. In addition to financial penalties, unpaid stamp duty can delay the legal transfer of title, prevent mortgage disbursement, and potentially breach your contractual obligations to the seller. Conveyancing lawyers typically factor BSD into the completion timeline and will remind clients of impending deadlines, but ultimate responsibility rests with the purchaser to ensure timely remittance through the official portal.
BSD vs ABSD — What’s the Difference?
Buyer Stamp Duty and Additional Buyer Stamp Duty (ABSD) are frequently confused, yet they serve entirely different policy objectives and operate independently of each other. BSD is a universal transaction tax applied to every residential property purchase in Singapore, regardless of whether the buyer is a Singapore Citizen, Permanent Resident, or foreign national. It funds general government revenue and scales progressively with property value.
ABSD, by contrast, is a cooling measure designed to moderate speculative demand and manage housing affordability. It applies only to specific buyer profiles and property types, with rates varying dramatically based on citizenship status and the number of existing residential properties owned. While BSD applies once to the marginal price bands outlined above, ABSD is calculated as a flat percentage on the entire purchase price or market value, whichever is higher. Crucially, ABSD is payable in addition to BSD, meaning both duties must be settled within the same 14-day window. First-time Singapore Citizen buyers pay only BSD, while subsequent purchases and foreign acquisitions attract significantly higher combined duty outlays.
How to Pay BSD in Singapore — Step by Step IRAS Guide
The Inland Revenue Authority of Singapore has fully digitized stamp duty payments, eliminating physical stamping and manual submissions. The process is straightforward, secure, and can be completed remotely by buyers or their authorized conveyancing representatives.
Step 1: Log in to the IRAS e-Stamping portal using your Singpass credentials or your property agent/lawyer’s authorized access.
Step 2: Select “Stamp Property Documents” and choose the appropriate document type, typically “Sale & Purchase Agreement” or “Option to Purchase.”
Step 3: Input the property address, purchase price, buyer particulars, and the date of signing or OTP exercise.
Step 4: The system will automatically calculate the exact BSD payable based on 2026 marginal rates. Review the breakdown carefully.
Step 5: Make payment via GIRO, credit card, PayNow, or internet banking. IRAS issues a digital Certificate of Stamp Duty immediately upon successful transaction.
Step 6: Download and store the certificate. Your lawyer will require it to register the transfer with SLA and proceed with mortgage documentation.
Payments are processed in real-time, and the digital certificate serves as legal proof of compliance. Always verify that the document reference number on the certificate matches your Sale & Purchase Agreement exactly to avoid administrative delays.

BSD for Commercial vs Residential Property
While residential BSD follows the progressive six-tier structure, commercial property acquisitions operate under a completely different duty framework. Commercial BSD applies to offices, retail spaces, industrial units, and mixed-use developments where commercial components are transacted separately. The rate is fixed at 4% of the purchase price or market value, whichever is higher, with no marginal tiers or progressive brackets.
This flat-rate structure simplifies calculations but can result in higher upfront costs for lower-valued commercial units compared to residential equivalents. For example, a $500,000 shophouse commercial component attracts exactly $20,000 in BSD, whereas a $500,000 residential unit would pay approximately $11,400 under the residential schedule. Buyers of commercial real estate should also note that ABSD does not apply
