Crypto Asset Disclosure / Transaction Declaration (Singapore)

A Crypto Asset Disclosure / Transaction Declaration in Singapore captures the particulars required for the filing or submission it supports.

MAS regulates digital payment token (DPT) services under the Payment Services Act 2019 (PSA), which requires entities providing DPT services — including cryptocurrency exchanges, wallet providers, and OTC trading desks — to hold a licence from MAS under Part 3 of the PSA. MAS Notice PSN01 (Prevention of Money Laundering and Countering the Financing of Terrorism — Digital Payment Token Service) imposes anti-money laundering (AML) and know-your-customer (KYC) obligations on licensed DPT service providers, including customer due diligence, transaction monitoring, and suspicious transaction reporting to the Suspicious Transaction Reporting Office (STRO) under the Corruption, Drug Trafficking and Other Serious Crimes (Confiscation of Benefits) Act (Cap. 65A).

IRAS's e-Tax Guide on Income Tax Treatment of Digital Tokens (published in 2020, updated in 2023) establishes the tax treatment framework. Payment tokens (Bitcoin, Ethereum) used to pay for goods and services are treated as barter transactions, with the value of goods or services received constituting taxable income. Security tokens representing ownership or debt interests are taxed according to the nature of the underlying instrument. Utility tokens are taxed based on the economic substance of the transaction. For individuals and businesses that trade cryptocurrency as a regular activity (buying and selling with profit-seeking intent), profits from trading are taxable as income under section 10(1)(a) of the Income Tax Act 1947. Casual investors who hold cryptocurrency as a long-term investment and realise gains upon disposal are generally not subject to income tax, as Singapore does not impose a capital gains tax.

The crypto asset disclosure document is used in several contexts: voluntary disclosure to IRAS during tax filing; mandatory AML declarations required by licensed DPT service providers under MAS Notice PSN01; due diligence declarations for financial institutions conducting enhanced customer due diligence on clients with cryptocurrency holdings; and corporate governance disclosures for companies holding cryptocurrency on their balance sheets under the Singapore Financial Reporting Standards (SFRS) and ACRA reporting requirements.

Singapore's status as a digital assets hub — with over 1,000 blockchain and cryptocurrency companies registered with ACRA according to industry estimates — makes the crypto asset disclosure a frequently used document across the financial services, technology, and legal sectors. The Singapore FinTech Association and the Blockchain Association Singapore provide industry guidance on standard practices for crypto asset documentation and regulatory compliance.

Singapore's position as a digital assets hub is supported by the regulatory clarity provided by MAS through the PSA licensing framework and the IRAS tax treatment guidelines. The MAS FinTech Regulatory Sandbox has been used by several cryptocurrency businesses to test innovative products before obtaining full licensing. The Blockchain Association Singapore and the Singapore FinTech Association publish industry standard practices for crypto asset documentation, regulatory compliance, and responsible innovation within MAS's regulatory perimeter.

A Crypto Asset Disclosure is needed in Singapore in several regulatory and commercial contexts where the holder or transactor of cryptocurrency must formally declare their holdings, transaction activity, and compliance status.

IRAS tax filing triggers the need for a crypto asset disclosure when an individual or business has derived income from cryptocurrency activities during the Year of Assessment. Under the Income Tax Act 1947, assessable cryptocurrency income includes: profits from cryptocurrency trading (buying and selling digital tokens with profit-seeking intent); income received in cryptocurrency for goods or services (treated as barter transactions at fair market value); cryptocurrency earned through mining, staking, or yield farming (if conducted as a business activity); and airdrops or hard fork tokens received in connection with a trade or business. IRAS expects taxpayers to maintain detailed records of all cryptocurrency transactions and to declare assessable income in their annual income tax returns.

MAS-licensed DPT service providers require customers to complete crypto asset declarations as part of their customer due diligence (CDD) obligations under MAS Notice PSN01. Cryptocurrency exchanges operating in Singapore — including licensed entities — must verify the source of customers' digital assets, screen transactions against sanctions lists, and maintain transaction records for at least five years. Enhanced due diligence applies to high-value transactions and customers from higher-risk jurisdictions.

Banking and financial institution due diligence in Singapore increasingly requires cryptocurrency holders to disclose their digital asset positions. Banks regulated by MAS (DBS, OCBC, UOB, and foreign banks licensed in Singapore) may request crypto asset declarations from corporate and individual clients during account opening, periodic reviews, or when unusual transaction patterns are detected. The disclosure helps the bank assess AML/CFT risk and comply with MAS Notice 626 (Prevention of Money Laundering and Countering the Financing of Terrorism — Banks).

Corporate governance and financial reporting under the Companies Act 1967 and SFRS require companies holding cryptocurrency on their balance sheets to disclose these holdings in their financial statements. ACRA requires companies to maintain accurate accounting records under section 199 of the Companies Act, and auditors assess the fair value and classification of cryptocurrency holdings under SFRS (Int) Interpretation.

Legal proceedings — including divorce proceedings in the Family Justice Courts, bankruptcy applications in the High Court, and estate administration — may require a party to disclose cryptocurrency holdings as part of the discovery of assets process.

A Singapore Crypto Asset Disclosure must contain the following categories of information to satisfy MAS regulatory requirements, IRAS tax filing obligations, and commercial due diligence standards.

**Declarant Identification** requires the full name of the individual or registered entity name, NRIC or passport number (for individuals), UEN registered with ACRA (for entities), residential or registered address, and contact details. For corporate declarants, the name and designation of the authorised officer making the disclosure must be stated.

**Cryptocurrency Holdings** lists each digital asset held by the declarant: the token name (Bitcoin, Ethereum, USDT, etc.), the quantity held, the wallet type (hardware wallet, software wallet, exchange-hosted wallet), the name of the exchange or custodian (for exchange-hosted holdings), and the approximate fair market value in Singapore dollars as at the disclosure date. The valuation should reference a recognised pricing source (CoinGecko, CoinMarketCap, or the exchange's published price).

**Transaction History Summary** provides an overview of cryptocurrency transactions during the relevant period: the number of buy, sell, transfer, and swap transactions; the total value of acquisitions and disposals in SGD; the exchanges and platforms used (including MAS-licensed DPT service providers and overseas exchanges); and the net gain or loss from trading activity. IRAS expects taxpayers engaged in cryptocurrency trading to maintain detailed transaction records, including timestamps, counterparties, and transaction hashes.

**Regulatory Compliance Declarations** confirm the declarant's compliance with applicable Singapore regulations: adherence to MAS Notice PSN01 requirements (for DPT service providers and their customers); compliance with IRAS income tax obligations for assessable cryptocurrency income; screening of transactions against the MAS sanctions list and the United Nations Security Council sanctions list; and reporting of suspicious transactions to STRO where required. The declarant must confirm that no cryptocurrency holdings originate from sanctioned jurisdictions or illicit activities.

**Source of Funds and Assets** states the origin of the cryptocurrency holdings — whether acquired through purchase with fiat currency, mining or staking rewards, salary or payment received in cryptocurrency, airdrops, initial coin offerings (ICOs), or inheritance. MAS Notice PSN01 requires DPT service providers to verify the source of customers' digital assets as part of enhanced customer due diligence.

**Tax Position Declaration** (for IRAS filing purposes) states whether the declarant's cryptocurrency activities constitute a trade or business (making profits taxable as income) or a personal long-term investment (making gains non-taxable under Singapore's no-capital-gains-tax regime). IRAS considers factors such as the frequency and volume of transactions, the holding period, the declarant's intention, and whether the activity is systematic in determining tax status.

**DeFi and Staking Positions** (where applicable) declares any holdings in decentralised finance protocols — liquidity pool positions, staking deposits, yield farming allocations, and governance token holdings — with the protocol name, token amounts, and estimated SGD value. IRAS has not issued specific guidance on DeFi taxation as of 2024, but the general income tax principles under the Income Tax Act 1947 apply, and taxpayers should declare DeFi income where it constitutes a trade or business activity.

The forms-legal.com Crypto Asset Disclosure template consolidates these elements into a structured declaration that can be used for IRAS tax filing support, MAS-regulated due diligence, banking KYC processes, and corporate governance reporting.

**Wallet and Custody Details** section requires the declarant to identify all cryptocurrency wallets and custodial arrangements: hardware wallets (Ledger, Trezor), software wallets (MetaMask, Trust Wallet), exchange-hosted wallets (with the exchange name and MAS licensing status), and institutional custody solutions (with the custodian name and regulatory status). For DeFi positions, the protocol name, blockchain network, and smart contract address should be recorded. MAS Notice PSN01 requires DPT service providers to verify that customers' wallets are not associated with sanctioned addresses.

Under Singapore law, the Payment Services Act 2019 and the Income Tax Act 1947 govern the core requirements for this type of document. Under Singapore law, Section 8 of the Employment Act 1968 (Cap. 91) and Section 13 of the Personal Data Protection Act 2012 (PDPA) govern the core requirements for this type of document.
