Stamp Duty Declaration (Singapore)

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

Section 4 of the Stamp Duties Act provides that every instrument chargeable with duty must be duly stamped before it is executed, and Section 22 sets out the time limits for stamping — 14 days from execution for instruments executed in Singapore, and 30 days from receipt in Singapore for instruments executed overseas. Late stamping attracts penalties under Section 46: S$10 or the duty amount (whichever is greater) for delays up to 3 months, and up to 4 times the duty for longer delays. IRAS administers stamp duty collection through the e-Stamping portal, an online system that allows taxpayers and their solicitors to declare instrument details, compute duty, and make payment electronically.

For property transactions, the Stamp Duties Act imposes several categories of duty. Buyer's Stamp Duty (BSD) under Section 22 and the First Schedule applies to all property purchases at progressive rates: 1% on the first S$180,000, 2% on the next S$180,000, 3% on the next S$640,000, and 4% on amounts exceeding S$1 million (with higher rates for residential properties above S$1.5 million introduced in the 2023 Budget). Additional Buyer's Stamp Duty (ABSD) under Section 22A applies additional rates depending on the buyer's residency status and the number of properties owned — Singapore citizens pay 20% ABSD on their second residential property, permanent residents pay 30% on their second, and foreigners pay 60% on any residential property purchase (rates as of 2024).

Seller's Stamp Duty (SSD) under Section 22B applies when a seller disposes of residential property within a holding period (currently 3 years from the date of acquisition). SSD rates range from 4% to 12% depending on the holding period, designed to discourage speculative short-term property trading. The Housing and Development Board (HDB) applies additional restrictions on resale timing that interact with SSD obligations.

For share transfers, stamp duty is payable at 0.2% of the higher of the purchase price or the net asset value of the shares under the First Schedule to the Stamp Duties Act. The Singapore Exchange (SGX) requires stamp duty to be paid on share transfers executed outside the Central Depository (CDP) system. Transfers of shares in Singapore-incorporated companies or shares in companies with substantial assets in Singapore are subject to duty regardless of where the transfer instrument is executed.

The Commissioner of Stamp Duties — a function exercised by the Comptroller of Income Tax at IRAS — has broad powers under Section 37 to assess the value of instruments and to raise additional assessments if the declared consideration is below market value. Section 39 provides for objections and appeals to the Commissioner's assessment, with further appeals to the High Court. The Stamp Duties (Relief from Stamp Duty upon Reconstruction or Amalgamation of Companies) Rules provide relief for qualifying corporate restructurings approved by IRAS.

A Stamp Duty Declaration to the Inland Revenue Authority of Singapore (IRAS) is required whenever a dutiable instrument is executed in connection with a property transaction, lease agreement, or share transfer in Singapore. Section 4 of the Stamp Duties Act (Cap. 312) mandates stamping of all chargeable instruments, and failure to declare and pay stamp duty within the prescribed timeframe triggers penalties under Section 46.

Purchasers of residential or commercial property in Singapore must submit a Stamp Duty Declaration and pay Buyer's Stamp Duty (BSD) — and Additional Buyer's Stamp Duty (ABSD) where applicable — within 14 days of executing the Option to Purchase or the Sale and Purchase Agreement. The conveyancing solicitor typically handles the e-Stamping submission through the IRAS e-Stamping portal, but the buyer bears the legal liability for timely payment under Section 22 of the Stamp Duties Act.

Sellers of residential property who dispose of the property within the Seller's Stamp Duty (SSD) holding period (currently 3 years from acquisition) must submit a declaration and pay SSD at rates ranging from 4% to 12%. The SSD obligation applies to all residential property sellers regardless of nationality, and the Housing and Development Board (HDB) tracks holding periods for HDB resale flats through its resale procedures.

Tenants and landlords executing lease agreements for residential or commercial premises must declare and pay stamp duty on the lease instrument. Lease duty rates under the First Schedule to the Stamp Duties Act depend on the lease term: 0.4% of the total rent for leases up to 1 year, 0.8% for leases of 1 to 3 years, and 1.6% for leases exceeding 3 years. The Singapore Land Authority (SLA) may require evidence of stamping for lease registration.

Parties to share transfer agreements involving shares in Singapore-incorporated companies or shares in companies with Singapore-situated assets must declare and pay stamp duty at 0.2% on the higher of the consideration or net asset value. The Accounting and Corporate Regulatory Authority (ACRA) requires evidence of stamping before registering share transfers in the company's register of members.

Companies undergoing corporate restructurings — mergers, amalgamations, or transfers of undertakings between related companies — may apply to IRAS for stamp duty relief under the Stamp Duties (Relief from Stamp Duty upon Reconstruction or Amalgamation of Companies) Rules. The declaration must demonstrate that the restructuring qualifies for relief and that no cash consideration exceeding 10% of the consideration is involved.

Foreign buyers of Singapore residential property face the highest ABSD rates (currently 60% for foreign individuals, with even higher rates for entities) and must submit the Stamp Duty Declaration with accurate residency status information. Misrepresentation of residency status to reduce ABSD liability constitutes a criminal offence under Section 62 of the Stamp Duties Act, punishable by fines and imprisonment.

A Stamp Duty Declaration submitted to the Inland Revenue Authority of Singapore (IRAS) through the e-Stamping portal must contain accurate and complete information about the dutiable instrument, the parties, the consideration, and the duty computation. The Stamp Duties Act (Cap. 312) grants the Commissioner of Stamp Duties powers to raise additional assessments and impose penalties for inaccurate or incomplete declarations.

The instrument details section identifies the type of dutiable instrument — Sale and Purchase Agreement, Option to Purchase, Tenancy Agreement, Deed of Assignment, Share Transfer Form, or other chargeable document — and provides the instrument execution date, which determines the stamping deadline. Section 22 of the Stamp Duties Act requires stamping within 14 days of execution for Singapore-executed instruments and 30 days for overseas-executed instruments.

The property or asset identification section provides the full address and title reference of the property (for property transactions registered with the Singapore Land Authority under the Land Titles Act 1993, Cap. 157), the postal code, the property type (HDB flat, private condominium, landed property, commercial property, industrial property), and the strata lot number where applicable. For share transfers, the section identifies the company by name, UEN registered with the Accounting and Corporate Regulatory Authority (ACRA), and the number and class of shares transferred.

The parties section records the transferor (seller, landlord, or share transferor) and transferee (buyer, tenant, or share transferee) by full name, NRIC or passport number, nationality, residency status, and the number of residential properties owned in Singapore. Residency status and property ownership count are critical for computing Additional Buyer's Stamp Duty (ABSD) — Singapore citizens, permanent residents, foreigners, and entities each face different ABSD rates, and the rate increases with the number of properties owned.

The consideration and value section declares the purchase price, premium, or rent payable, and the open market value of the property or shares. The Commissioner of Stamp Duties computes duty on the higher of the declared consideration and the market value under Section 37 of the Stamp Duties Act. For property transfers between related parties at below-market value (such as gifts or transfers between family members), the Commissioner may assess duty on the market value determined by an independent valuation. Licensed valuers registered with the Singapore Institute of Surveyors and Valuers (SISV) or the Royal Institution of Chartered Surveyors (RICS) provide acceptable market valuations.

The duty computation section calculates the total stamp duty payable — comprising Buyer's Stamp Duty (BSD), Additional Buyer's Stamp Duty (ABSD) where applicable, and Seller's Stamp Duty (SSD) where applicable. BSD rates are set out in the First Schedule to the Stamp Duties Act, ABSD rates are prescribed under Section 22A, and SSD rates under Section 22B. The IRAS e-Stamping portal automatically computes duty based on the declared information, but the declarant is responsible for the accuracy of the inputs.

Remission and relief applications, where applicable, must be included in the declaration. IRAS provides stamp duty remission for specific situations, including the remission for married couples transferring property between themselves, the relief for corporate restructurings under the Stamp Duties (Relief from Stamp Duty upon Reconstruction or Amalgamation of Companies) Rules, and the aborted sale relief under Section 22(6) where a transaction does not complete. Each remission has specific qualifying conditions published in IRAS e-Tax Guides.

The declaration and undertaking section requires the declarant to confirm that all information provided is true, correct, and complete. Section 62 of the Stamp Duties Act imposes criminal penalties for furnishing false information — including fines up to S$10,000 and imprisonment up to 7 years. Forms-legal.com provides the Stamp Duty Declaration template for preparatory reference before submitting through the IRAS e-Stamping portal, allowing parties and their solicitors to organise all required information before initiating the online declaration process.
