IRAS Stamp Duty Declaration (Property) Singapore

An IRAS Stamp Duty Declaration (Property) in Singapore sets out the income, deductions, and tax position to be reported to the authority.

The BSD rates for residential property in Singapore follow a progressive structure under the First Schedule of the Stamp Duties Act: 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$1,500,000; and 6% on the portion exceeding S$3,000,000. For non-residential property (commercial, industrial), the rates are: 1% on the first S$180,000; 2% on the next S$180,000; and 3% on the portion exceeding S$360,000. The Singapore Land Authority (SLA) maintains the register of land titles, and stamp duty must be paid before the transfer can be registered with SLA under the Land Titles Act 1993 (Cap. 157).

Additional Buyer’s Stamp Duty (ABSD) may apply on top of BSD for certain categories of buyers. Singapore Citizens purchasing their second residential property pay 20% ABSD, and 30% on their third and subsequent properties. Singapore Permanent Residents (SPRs) pay 5% on their first residential property, 30% on their second, and 35% on their third and subsequent properties. Foreign buyers pay 60% ABSD on any residential property purchase. ABSD rates are prescribed by the Stamp Duties (Section 4A) Order and are subject to periodic revision by the Ministry of Finance.

An IRAS Stamp Duty Declaration differs from an Additional Buyer Stamp Duty Declaration, which specifically addresses the ABSD component for qualifying buyers. A Mortgage Discharge Application relates to the removal of a mortgage from the land register. A Landed Property Sale Agreement is the underlying transaction document that triggers the stamp duty obligation.

Seller’s Stamp Duty (SSD) may also apply when residential property is sold within a specified holding period — currently 12 months from the date of acquisition. SSD rates range from 12% (sold within the first year) and are designed to discourage speculative property trading. Late payment attracts a penalty of up to 4 times the stamp duty amount under Section 46 of the Stamp Duties Act. Under Singapore law, the Stamp Duties Act (Cap. 312) and Section 13 of the Personal Data Protection Act 2012 (PDPA) govern the core requirements for this type of document.

An IRAS Stamp Duty Declaration in Singapore is required whenever a dutiable instrument relating to the purchase, transfer, or lease of immovable property is executed.

When a buyer purchases residential property — whether an HDB flat, private condominium, landed property, or executive condominium — Buyer’s Stamp Duty (BSD) must be declared and paid through the IRAS e-Stamping portal within 14 days of the date the Option to Purchase (OTP) is exercised. Under the Stamp Duties Act (Cap. 312), the OTP becomes a dutiable instrument upon exercise, and stamp duty is computed on the purchase price or the market value assessed by the Chief Valuer (whichever is higher).

When a buyer who is a Singapore Permanent Resident, a foreigner, or a Singapore Citizen purchasing a second or subsequent residential property executes a purchase, Additional Buyer’s Stamp Duty (ABSD) must be declared in addition to BSD. The ABSD declaration requires the buyer to state their citizenship status, the number of residential properties currently owned, and the applicable ABSD rate.

When commercial or industrial property is purchased — including office units, retail shops, factory premises, and warehouse spaces — BSD is payable at the non-residential property rates. Non-residential property transactions are not subject to ABSD or SSD.

When property is transferred by way of gift (voluntary transfer without monetary consideration), IRAS assesses stamp duty based on the market value of the property as determined by the Chief Valuer. A Stamp Duty Declaration must be filed for gift transfers, and the transferee is responsible for payment.

When a lease of property with a term exceeding 4 years is granted, stamp duty is payable on the lease instrument based on the average annual rent (AAR) multiplied by the lease term. The HDB Resale Checklist should be reviewed for HDB-specific stamp duty considerations, as HDB flats have additional eligibility and pricing rules. Under Singapore law, the Stamp Duties Act (Cap. 312) and Section 13 of the Personal Data Protection Act 2012 (PDPA) govern the core requirements for this type of document.

An IRAS Stamp Duty Declaration for property transactions in Singapore must contain the following mandatory elements for processing through the IRAS e-Stamping system.

Buyer details must include the buyer’s full legal name, NRIC number (for Singapore Citizens and PRs), FIN number (for foreigners), nationality, citizenship status, and the number of residential properties currently owned by the buyer. Citizenship status determines the applicable ABSD rate, and IRAS cross-references the buyer’s property ownership records with SLA and HDB databases to verify the declared information.

Property details must specify the property address, type (HDB flat, private residential, landed, commercial, industrial), land area and floor area, title reference (lot number and mukim for freehold properties, or lease reference for leasehold properties), and whether the property is classified as residential or non-residential under the Property Tax Act (Cap. 254). The property classification determines the applicable BSD rate schedule.

BSD calculation must show the purchase price or market value (whichever is higher), the applicable BSD rates under the First Schedule of the Stamp Duties Act (Cap. 312), and the total BSD payable. IRAS provides an online BSD calculator on the e-Stamping portal, and the declared BSD must match the calculator output for the stated purchase price.

Additional Buyer’s Stamp Duty section must state whether ABSD applies, the buyer’s residency category (Singapore Citizen, SPR, foreigner, or entity), the number of residential properties owned, the applicable ABSD rate, and the ABSD amount. IRAS verifies ABSD eligibility through automated checks against SLA and HDB records.

Payment and filing details must confirm the filing date (within 14 days of execution for instruments executed in Singapore), the payment method (electronic payment through the e-Stamping portal via GIRO, credit card, or PayNow), and the solicitor or conveyancing lawyer handling the transaction. Under Section 46 of the Stamp Duties Act, late stamping attracts a penalty — S$10 or an amount equal to the stamp duty payable (whichever is greater) if stamped within 3 months, and up to 4 times the stamp duty for later stamping.

The forms-legal.com IRAS Stamp Duty Declaration template covers all mandatory fields including the BSD rate schedules for residential and non-residential property, the ABSD calculation section, and the e-Stamping filing timeline. Buyers should also review the Landed Property Sale Agreement template for the underlying transaction document. Under Singapore law, the Stamp Duties Act (Cap. 312) and Section 13 of the Personal Data Protection Act 2012 (PDPA) govern the core requirements for this type of document. Under Singapore law, Section 8 of the Employment Act 1968 (Cap. 91) and Section 169 of the Companies Act 1967 (Cap. 50) govern the core requirements for this type of document.
