Additional Buyer Stamp Duty Declaration (Singapore)

An Additional Buyer Stamp Duty Declaration in Singapore captures the particulars required for the filing or submission it supports.

ABSD is an additional layer of stamp duty imposed on top of the standard Buyer's Stamp Duty (BSD) payable under Section 22 of the Stamp Duties Act (Cap. 312). BSD is assessed on a progressive scale: 1% on the first S$180,000 of the purchase price or market value (whichever is higher), 2% on the next S$180,000, 3% on the next S$640,000, and 4% on the portion exceeding S$1,000,000 — with an additional 5% on the portion exceeding S$1,500,000 and 6% on the portion exceeding S$3,000,000 (effective from 15 February 2023). ABSD is then calculated as a flat percentage of the entire purchase price or market value, with the rate determined by the buyer's residency status, citizenship, and the number of residential properties already owned.

The current ABSD rates effective from 27 April 2023 are structured as follows: Singapore citizens pay 0% on their first residential property, 20% on their second, and 30% on their third and subsequent properties. Singapore Permanent Residents (PRs) pay 5% on their first property, 30% on their second, and 35% on their third and subsequent properties. Foreigners (including non-PR holders) pay 60% ABSD on any residential property purchase. Entities (companies, trusts, and associations) pay 65% ABSD on any residential property acquisition. The Urban Redevelopment Authority (URA) and the Housing and Development Board (HDB) coordinate with IRAS on property transaction data to verify ABSD declarations.

ABSD remission may be available in specific circumstances. Married couples consisting of a Singapore citizen and a Singapore PR purchasing their first matrimonial property jointly may apply for ABSD remission under the Stamp Duties (Married Couple Remission) Rules. Housing developers who purchase residential land for development and sale may qualify for ABSD remission under the Stamp Duties (Housing Developers — Remission of ABSD) Rules, subject to completing and selling all units within a prescribed timeframe (typically 5 years from the date of purchase). The Monetary Authority of Singapore (MAS) and the Ministry of National Development (MND) jointly oversee the ABSD framework as part of Singapore's broader macroprudential property measures.

ABSD forms part of a broader set of property cooling measures implemented by the Singapore government since 2009, which also include Seller's Stamp Duty (SSD) under the Stamp Duties (Seller's Stamp Duty) Rules, Total Debt Servicing Ratio (TDSR) limits imposed by MAS, and Loan-to-Value (LTV) ratio caps on property financing. The Commissioner of Stamp Duties, appointed under Section 3 of the Stamp Duties Act, has broad powers to investigate ABSD declarations and to impose penalties for under-declaration or false declarations under Section 62 of the Stamp Duties Act. Penalties for ABSD evasion or under-declaration can reach up to 4 times the amount of duty that should have been paid, and criminal prosecution may follow in cases involving deliberate fraud.

An Additional Buyer's Stamp Duty Declaration is required in Singapore whenever a person or entity purchases residential property and ABSD is applicable based on the buyer's profile and existing property ownership.

When a Singapore citizen purchases a second residential property, the citizen must declare and pay ABSD at the rate of 20% of the purchase price or market value. Many Singapore citizens purchase a second property as an investment while retaining their owner-occupied HDB flat or private residence. The Housing and Development Board (HDB) maintains records of HDB flat ownership, and IRAS cross-references this data when assessing ABSD liability through the e-Stamping system.

When a Singapore Permanent Resident purchases their first residential property, ABSD of 5% applies under the current rates effective from 27 April 2023. PRs upgrading from their first property to a second residential property face a substantially higher ABSD rate of 30%, which the Ministry of Finance introduced as a demand management measure targeting investment purchases by non-citizens.

When a foreigner — including an Employment Pass holder, S Pass holder, or Work Permit holder who has not obtained permanent residency — purchases any residential property in Singapore, ABSD of 60% of the purchase price is payable. The 60% rate, introduced in the April 2023 revision, represents one of the highest foreign buyer stamp duties globally and was designed to prioritise housing affordability for Singapore citizens and PRs. The Singapore Land Authority (SLA) administers the Residential Property Act (Cap. 274), which separately restricts foreign ownership of landed residential property.

When a corporate entity, trust, or association purchases residential property in Singapore, ABSD of 65% applies. The entity ABSD rate is designed to discourage the use of corporate structures to circumvent individual ABSD obligations. IRAS examines the beneficial ownership of purchasing entities, and the Stamp Duties (Anti-Avoidance) provisions empower the Commissioner of Stamp Duties to disregard arrangements that have the effect of avoiding or reducing ABSD liability.

When a married couple seeks ABSD remission on their joint purchase of a first matrimonial home, both spouses must complete the ABSD declaration and submit a separate remission application to IRAS. The remission is available where at least one spouse is a Singapore citizen, the property is their first jointly owned residential property, and the application is filed within 6 months of the date of the instrument of transfer.

An Additional Buyer's Stamp Duty Declaration in Singapore must contain several mandatory elements to satisfy IRAS requirements under the Stamp Duties Act (Cap. 312) and the ABSD Rules.

Declaration details must specify the type of property transaction — whether the purchase is under an Option to Purchase (OTP), a Sale and Purchase Agreement (SPA), or a transfer instrument — and the date of the instrument. IRAS assesses ABSD based on the date of the instrument, and the applicable ABSD rate is the rate in force on that date, not the date of completion or property handover.

Buyer identification and residency status form the core of the ABSD declaration. For individual buyers, the declaration must state the buyer's full name, NRIC number (for citizens and PRs) or FIN/passport number (for foreigners), nationality, PR status (if applicable), and date of obtaining PR status. IRAS determines the applicable ABSD rate based on the buyer's citizenship and PR status at the date of the instrument, so accurate identification is critical. For entity buyers, the company name, UEN, and the identity of the beneficial owners must be provided.

Property details must identify the property being purchased, including the full address, property type (HDB flat, private condominium, landed property, or executive condominium), land lot number, and the strata title plan number if applicable. The Urban Redevelopment Authority (URA) property classification determines whether the property is residential (and therefore subject to ABSD) or non-residential (exempt from ABSD). Mixed-use properties with a residential component are assessed for ABSD on the residential portion only.

The ABSD amount must be calculated and declared based on the higher of the purchase consideration and the market value of the property. The forms-legal.com Additional Buyer Stamp Duty Declaration template includes fields for stating the purchase consideration, the market value (if different), the buyer's existing property count, and the resulting ABSD rate and payable amount. IRAS may request a valuation report from a licensed valuer accredited by the Singapore Institute of Surveyors and Valuers (SISV) if the stated purchase consideration appears below market value.

Existing property ownership must be declared in full. The buyer must list all residential properties currently owned in Singapore, including HDB flats, private residential properties, and any properties held through nominees or trusts. IRAS cross-references the declaration against the Singapore Land Authority (SLA) records and the HDB ownership database. Under-declaration of existing property ownership constitutes an offence under the Stamp Duties Act (Cap. 312) and may result in penalties of up to 4 times the amount of stamp duty evaded under Section 62.

Remission eligibility should be addressed if the buyer qualifies for ABSD remission. Married couples applying for the spouse remission must declare their marital status, the date of marriage, the citizenship status of each spouse, and confirm that neither spouse currently owns a residential property in Singapore. Housing developers must declare the development timeline and the expected completion date to qualify for the developer remission under the Stamp Duties (Housing Developers — Remission of ABSD) Rules.

Supporting valuation documentation should accompany the ABSD declaration when the purchase consideration differs from the market value or when IRAS requests verification. Licensed valuers accredited by the Singapore Institute of Surveyors and Valuers (SISV) provide independent property valuations that IRAS accepts for stamp duty assessment purposes. For related-party transactions, such as transfers between family members, associated companies, or parties acting in concert, IRAS routinely requests a professional valuation to verify that the declared consideration reflects the true market value. Under Section 22 of the Stamp Duties Act (Cap. 312), stamp duty is assessed on the higher of the consideration and market value, and declaring a purchase price below market value does not reduce the ABSD payable.

Conveyancing lawyer coordination is a practical element of the ABSD declaration process. Singapore law requires property purchase instruments to be stamped before the transfer can be registered with the Singapore Land Authority (SLA), and conveyancing lawyers typically manage the e-Stamping submission, ABSD calculation, and payment on behalf of their clients. The Law Society of Singapore's Conveyancing Practice Directions set out the professional obligations of lawyers handling property transactions, including verification of the buyer's citizenship and residency status for ABSD purposes.
