Singapore Crypto Tax Guide 2026: IRAS Rules for Investors and Businesses

Singapore is often called crypto-friendly, and for long-term holders that reputation is mostly earned. There is no capital gains tax. If you bought ETH in 2020 and sold it in 2026 for a substantial profit, that gain is generally not taxable.

The picture changes quickly once you start trading actively, running a Web3 business, or earning crypto income. The Inland Revenue Authority of Singapore (IRAS) does not tax capital gains, but it does tax trading income under Section 10(1) of the Income Tax Act. The line between "investor" and "trader" is the single most important question in Singapore crypto tax, and it is determined by facts, not by what you call yourself.

This guide walks through how IRAS actually treats digital tokens in 2026, where the genuine pitfalls are, and what Singapore-incorporated Web3 businesses need to keep in order.

Why Singapore has no capital gains tax (and what that doesn't cover)

Singapore's tax system simply does not include a capital gains tax. There is no equivalent to the UK's CGT or the US long-term capital gains regime. If a transaction is genuinely capital in nature, gains are not taxable. Losses are also not deductible.

That sounds clean. The catch is that "capital in nature" is a determination IRAS makes based on the substance of the activity, not on the asset class. Just because an asset is called crypto does not mean every disposal is a capital event. If IRAS concludes you are carrying on a trade in digital tokens, profits are taxable as income under Section 10(1)(a) of the Income Tax Act.

The same applies in reverse to losses. Genuine investors cannot deduct losses, but if you are classified as a trader, losses can offset trading income.

So the first question is never "what is the tax rate?" It is "am I an investor or a trader in IRAS's view?"

The investor vs trader test — IRAS factors

IRAS applies what are commonly called the "badges of trade", a set of factors developed in case law and applied across asset classes including crypto. No single factor is decisive. IRAS looks at the overall picture.

A retail investor with a few BTC and ETH wallets, holding for years, will almost always be on the investor side. A founder running an automated trading desk from Singapore, with daily volumes and leveraged positions, is likely a trader.

The grey zone is where most arguments happen: someone who DCAs, does occasional swaps, runs a few DeFi positions, claims airdrops. Whether IRAS treats that as investing or trading depends on facts that may not feel obvious in the moment but will be reconstructed from your records later.

Income tax on crypto trading (when it applies)

When IRAS classifies activity as a trade, profits are taxable under Section 10(1)(a) of the Income Tax Act. For individuals, that means progressive personal income tax rates, which top out at 24 percent for residents above SGD 1 million in chargeable income (Year of Assessment 2024 onwards).

Two practical points matter:

1. Mark-to-market is not the rule for individuals. Trading profits are generally recognised on disposal, when you actually sell or swap. Unrealised gains on unsold tokens are not taxed each year for individual traders.
2. Crypto-to-crypto swaps are disposals if you are a trader. Selling ETH for USDC is a realisation event. If you are an investor, the gain is non-taxable. If you are a trader, the gain is income.

Cost basis and lot accounting are not prescribed in the same way they are in the UK. IRAS expects a reasonable, consistent method (typically FIFO or weighted average) applied across all wallets and exchanges, and documented.

GST (Goods and Services Tax) on digital payment tokens — exempt since 2020

Before 1 January 2020, supplying crypto was treated as a taxable supply for GST. Buying a coffee with BTC could create GST on both legs, which made crypto payments structurally awkward.

That changed with the 2020 amendment. IRAS's e-Tax Guide on GST treatment of digital payment tokens introduced a category of exempt supply for "digital payment tokens" (DPTs), which broadly covers cryptographic tokens used or intended to be used as a medium of exchange: BTC, ETH, most major altcoins, and many stablecoins.

Practical consequences:

• The exchange of one DPT for another DPT is an exempt supply.
• Using DPTs to pay for goods or services is disregarded as a supply by the buyer (the sale of the goods or services itself is still subject to GST as normal).
• Lending of DPTs and provision of DPTs as collateral are also treated as exempt supplies.

Tokens that do not meet the DPT definition (most NFTs, utility tokens with limited fungibility, and security tokens) are not covered by this exemption and follow the standard GST rules.

GST registration in Singapore is required when annual taxable turnover exceeds SGD 1 million. Exempt supplies do not count toward that threshold, but if your business has both DPT and non-DPT activity, the line between exempt and taxable supplies needs to be tracked carefully.

Staking, mining, airdrops — IRAS treatment

IRAS's e-Tax Guide on the income tax treatment of digital tokens (first issued 2020, with subsequent updates) sets out how it views recurring crypto income. The treatment depends on whether the activity is carried on as a trade or business, and on the nature of the receipt.

The pattern is consistent: passive receipts to a long-term holder tend to be outside the income tax net, while receipts that look like compensation for services, or accrue to someone running a business, are taxable. Once a token is received as taxable income, its market value at receipt becomes the cost base for any future disposal.

If your activity is on the trading side, the subsequent sale of any received tokens is itself a taxable event. If you are an investor, the eventual disposal is generally outside the tax net.

Crypto businesses: corporate income tax, foreign income exemption

Singapore-incorporated entities (exchanges, custodians, asset managers, foundations, or operating companies for DAOs) pay corporate income tax at a flat 17 percent on chargeable income. Several features make this manageable in practice:

• Partial tax exemption: 75 percent exemption on the first SGD 10,000 of chargeable income and 50 percent on the next SGD 190,000.
• Start-up tax exemption: For qualifying new companies, 75 percent exemption on the first SGD 100,000 and 50 percent on the next SGD 100,000 for the first three years of assessment.
• Foreign-sourced income exemption (Section 13(8)): Foreign-sourced dividends, branch profits, and service income may be exempt when remitted to Singapore, subject to the "subject to tax" and "headline rate" conditions.

For a Web3 business, the practical questions usually are: where is the income sourced, what counts as trading versus capital, and how are token treasuries treated on the balance sheet.

Token treasury accounting in Singapore generally follows Singapore Financial Reporting Standards (SFRS), which currently treat crypto held by a non-trading entity as an intangible asset measured at cost less impairment, or at fair value if held for trading. The accounting treatment does not always match the tax treatment, and reconciling the two is one of the more time-consuming parts of a Singapore Web3 audit.

ICOs and token issuance from Singapore

Singapore has been a common jurisdiction for token issuance, and IRAS has issued specific guidance. The tax treatment of a token issuance depends primarily on the nature of the token issued.

• Payment tokens (DPTs): Proceeds raised are generally treated as capital receipts if the issuer is genuinely raising funds for capital purposes. If the issuer is in the business of trading tokens, treatment can differ.
• Utility tokens: Proceeds are generally treated as deferred revenue and recognised over time as the underlying services are provided. This often results in taxable income recognition spread across several years.
• Security tokens: Treated under the same principles as conventional securities. Equity-like tokens follow equity rules, debt-like tokens follow debt rules.

The Monetary Authority of Singapore (MAS) regulates token issuance separately under the Securities and Futures Act and the Payment Services Act. Tax treatment and securities regulation are independent questions, and getting one right does not solve the other.

Reporting and record-keeping for IRAS

IRAS requires taxpayers to keep proper records for at least five years. For crypto, that means more than just exchange statements.

A defensible record set typically includes:

• All wallet addresses controlled by the taxpayer or entity.
• Full transaction history for each wallet and exchange account.
• The SGD value of each transaction at the time it occurred, with the exchange rate source documented.
• Cost basis records for every disposal, with the chosen accounting method applied consistently.
• Documentation of intent: board minutes for a treasury, investment mandates, or trading strategy documents that support the investor or trader classification.

For individuals, crypto activity is reported as part of the annual Form B / B1 income tax return. There is no separate crypto schedule. Trading profits, employment income paid in crypto, and other taxable receipts are folded into the relevant lines.

For companies, crypto activity flows through the Form C / C-S corporate return and supporting financial statements. IRAS has been increasing its data-matching capabilities and has obtained information on Singapore residents from major exchanges in recent years. Quietly omitting crypto activity is a poor strategy.

FAQ

Do I pay tax in Singapore if I just hold BTC for years and sell? If your activity is genuinely investment in nature (long holding period, no trading pattern, own funds), gains on disposal are generally not taxable in Singapore. Document the holding pattern in case the classification is questioned later.

Are stablecoin transactions taxable? For investors, swapping into and out of stablecoins is not taxable. For traders, each swap is a disposal and potentially generates trading income or loss. GST is not charged on DPT-to-DPT exchanges.

I am an employee paid partly in tokens. What do I report? Employment income paid in crypto is fully taxable as employment income at the SGD market value on the date received. Your employer should report this on the IR8A. Keep your own records of the receipt value because it becomes your cost base for any future disposal.

Does staking through a Singapore exchange create a taxable event? Receipt of staking rewards by a passive holder is generally not taxable. If you are running staking as a business, or staking is part of a broader trading activity, rewards are taxable as income at fair market value on receipt.

My DAO is incorporated as a Singapore foundation. How is the treasury taxed? A Singapore-incorporated foundation is a taxable entity. Treasury appreciation on long-held tokens is generally not taxable, but trading activity, fee income, and any taxable services rendered will be subject to corporate income tax at 17 percent. The investor versus trader distinction applies at the entity level just as it does for individuals.
