Digital Tokens and Income Tax: Payments, Mining and ICOs

Scope, edition and token classification

This article follows the nineteen-page IRAS guide published on 30 January 2026, including both annexes. Earlier editions appeared on 17 April and 9 October 2020. It concerns income tax for businesses and individuals receiving, spending, trading or issuing digital tokens. Existing income-tax provisions and applicable tax treaties govern the outcomes; GST is addressed in a separate digital-payment-token guide.

Classification follows the actual rights and use of a token rather than its name. Payment tokens such as Bitcoin and Ether function as payment instruments; utility tokens give access to goods or services; security tokens represent ownership or investment rights in underlying assets. Unusual or evolving arrangements may require individual examination. An ICO is an initial public token issue, often used for fundraising. Mining verifies transactions and adds them to a blockchain while releasing new tokens.

Payment tokens are property, and payments are barter

For income-tax purposes, the guide treats payment tokens as intangible property rather than government-issued fiat currency. Paying for goods or services with them is therefore a barter transaction. A seller recognises the value of the underlying supply, while a buyer determines any deduction using the value of the goods or services acquired. Ordinary deduction conditions still apply: using a token does not turn a private or capital purchase into an allowable business expense.

Valuation, evidence and unrealised changes

IRAS does not prescribe one mandatory token valuation method. A taxpayer may choose a rate that reasonably reflects the token’s value, provided it is verifiable and the methodology is applied consistently from year to year. An average of exchange quotations is one possible method; where quotations are unavailable, other evidence must substantiate the valuation. Retain that evidence because IRAS may ask how the amount was determined.

A fair-value gain or loss recognised in accounts while the payment token remains undisposed is not taxable or deductible under the guide’s unrealised-gain treatment. For taxable trading disposals of tokens bought at different prices, FIFO and weighted-average cost are accepted. LIFO is expressly excluded.

Where payment-token income arises

When a token gain is taxable, its source depends on the operation that produced it and where those activities took place. A business carrying out most of its operations in Singapore is likely to have Singapore-source income. Relevant facts include offices and employees here and the location of key activities such as operating and maintaining an exchange platform. No single fact settles the question; the operations must be examined together.

Utility tokens and security-token returns

A utility token may resemble a voucher for future services or a key giving platform access. The purchase is a prepayment. When the token is redeemed, an allowable business deduction may arise for the amount incurred, subject to ordinary deduction rules; redemption does not normally create taxable income for the user.

Security tokens may represent debt, equity or other investment rights, including a unit in a collective investment scheme. Their contractual rights determine whether returns are interest, dividends or another distribution and how those returns are taxed. On disposal, the holder must separately decide whether the asset and resulting gain or loss are capital or revenue in nature.

Annex A: receiving tokens for business supplies

The contract determines the income amount, assuming it reflects the open-market value of the services or goods. If a business is owed S$100 payable in Bitcoin, its income is S$100. If it is owed one Bitcoin instead, its income is the value of that Bitcoin when the income accrues. The two agreements can therefore produce different taxable amounts. IRAS generally respects the commercial form unless it does not match the substance.

Annex A: employment remuneration and purchases

An employee paid in tokens is taxed on employment income when it accrues, with the contract determining the value in the same way as a business supply. Under the guide’s stated moratorium treatment, a restricted payment accrues when the restriction is lifted and is taxable then.

Buying a payment token is not itself a taxable event. However, the buyer’s intention and the badges of trade matter when a later disposal is assessed: a trading asset and a long-term capital investment can lead to different results.

Annex A: mining on one’s own account

A miner who keeps tokens for personal use or long-term investment may have capital gains or losses on disposal, which are neither taxable nor deductible. A miner conducting a trading activity is taxed on disposal profits and can deduct qualifying losses. Merely successfully mining and holding a token does not, under this guide, create income at that point; the profit is assessed when the token is disposed of.

A company is generally formed to earn profit, so its mining activity is treated as a business. Qualifying mining expenses are deductible when incurred from business commencement, when the profit-making structure is established and commercial activity begins. Buying mining equipment and selling mined tokens can indicate commencement. For an individual, mining is initially regarded as a hobby: capital disposal gains are untaxed and mining costs are not deductible. Habitual and systematic activity aimed at profit may instead constitute a taxable mining vocation.

Annex A: mining services, airdrops and hard forks

A miner acting for customers and returning the mined tokens to them is providing a service. The service fees are taxable, even though the miner does not retain the tokens.

An airdrop received without providing anything in return is not income at receipt. Tokens given for a service, or in expectation of one, can instead be taxable income. A hard fork can produce a separate token alongside the original; a holder receiving it without doing anything in return has a non-taxable windfall at receipt. A trader’s subsequent disposal gains remain taxable, including for tokens originally received through an airdrop or hard fork.

Annex A: spending tokens creates two separate questions

First, calculate any deduction for the goods or services purchased under sections 14 and 15. If S$100 is owed and settled in Bitcoin, the relevant expense is S$100. If one Bitcoin is owed, use its value when the supplier becomes entitled to it, assuming the contract reflects open-market value.

Second, examine the gain or loss on disposing of the token itself. A revenue disposal can create a taxable gain or deductible loss when realised and accrued. This separate calculation is needed even where the purchased goods or services qualify for a deduction. Exchanging a token for fiat currency or for a different payment token also requires the capital-versus-revenue assessment; a crypto-to-crypto conversion is still a disposal.

Annex B: payment-token fundraising proceeds

For an issuer carrying on a trade in payment tokens, issued tokens are generally trading stock and proceeds are taxable on issuance, when willing parties can trade the issued token. The guide notes that this type of ICO is uncommon and the precise facts may need examination. Its overall rule does not mean every token fundraising receipt is automatically taxable.

Annex B: utility and security fundraising proceeds

A utility-token issuer promises future goods or services. The receipts are revenue in nature, but generally deferred until the performance obligation is met, for example when goods are delivered or platform services are provided. Receiving the funds and fulfilling the promise are distinct events.

A security-token issue grants rights resembling those of a shareholder, lender or another investor. The fundraising receipt is capital in nature and is not taxable on issue. It may be called an STO. Interest, dividends and other distributions received by investors remain subject to their applicable rules, including withholding obligations where relevant payments go to non-residents. The issuer’s deduction for distributions is determined under sections 14 and 15; issuing a token does not make every distribution deductible.

Annex B: source of fundraising and investment returns

For payment and utility fundraising, consider the issuer’s physical presence, the location and conduct of ICO marketing, where participants are based and where blockchain developers work. These non-exhaustive factors are assessed together because digitally executed transactions may span several countries. For investment returns, ordinary source rules apply: interest generally refers to where lending occurs and dividends to the paying company’s tax residence. Missing information about an issuer may require a closer factual examination.

Failed ICOs and pre-commencement expenses

If an issuer cannot complete a promised platform and refunds investors, the refunded amount is not taxed on the issuer. Any retained receipts still need classification as capital or revenue, taking account of the main business, the purpose of the ICO and the contractual obligations. A failed project does not by itself make retained proceeds tax-free.

An ICO may precede business commencement. The usual pre-commencement expense rules apply; section 14R may allow expenses from the basis period relating to the YA immediately before the deemed commencement date. Existing conditions also govern carrying unused loss items forward or using Group Relief.

Founder tokens: remuneration or capital contribution

Tokens rewarding a founder’s development services are remuneration and revenue in nature. Tokens representing ownership or voting rights in return for a money contribution to the company or ICO may instead be a capital asset. Determine why the award was made rather than classifying every founder allocation alike.

Service-related tokens are taxable when the founder becomes entitled to them. The guide states that, where a lock-in period or moratorium applies, accrual is deferred until it ends; taxation then uses the token value at release. The restriction and entitlement terms therefore affect both timing and amount.

Records, contact routes and amendments

Keep transaction dates, quantities received or sold, values at transaction time, the exchange rates used, transaction purposes, customer or supplier details for purchases and sales, ICO information and expense invoices or receipts. These records must be available to IRAS on request. The PDF lists 1800-356 8622 for corporate tax and 1800-356 8300 for individual tax enquiries.

The October 2020 revision clarified that security tokens can represent other securities or investment instruments, with returns beyond interest and dividends. The January 2026 revision updated statutory numbering to the Income Tax Act 1947 (2020 Revised Edition) and made editorial changes. Both annexes are included in the explanations above; the source link allows readers to examine the original wording.
