Tax Filing for Virtual Asset Trading: Are Bitcoin and Ethereum Gains Taxable?

Hong Kong’s Inland Revenue Department (IRD) has not issued specific guidance on virtual assets, but the 2024-25 Budget Speech delivered by Financial Secretary Paul Chan Mo-po on 28 February 2024 signalled the government’s intent to finalise a regulatory framework for over-the-counter (OTC) virtual asset trading by mid-2025. This follows the Securities and Futures Commission’s (SFC) licensing regime for virtual asset trading platforms, which came into full effect on 1 June 2023. For Hong Kong taxpayers who have traded Bitcoin, Ethereum, or other virtual assets, the central question remains: are gains from such trading subject to Hong Kong profits tax? The answer turns on the territorial source principle of the Inland Revenue Ordinance (Cap. 112) and the nature of the trading activity—whether it constitutes a trade, a capital gain, or an offshore transaction. This article examines the applicable tax treatment, the implications of the SFC’s licensing regime, and the practical steps taxpayers should take for the 2024-25 tax year.

The Territorial Source Principle and Virtual Asset Trading

Hong Kong’s tax system operates on a territorial basis. Under Section 14 of the Inland Revenue Ordinance (Cap. 112), profits tax is chargeable only on profits “arising in or derived from Hong Kong” from a trade, profession, or business carried on in the territory. This principle applies equally to virtual asset trading, though its application is more complex than for traditional securities.

Determining the Source of Profits from Virtual Asset Trading

The IRD has historically applied the “operations test” to determine the source of profits, as established in the leading case CIR v. Hang Seng Bank Ltd (1990) 3 HKTC 351. The test asks where the operations that produce the profit take place. For virtual asset trading, this typically involves the location of the trading platform’s servers, the execution of orders, and the management of the trading activities.

For a Hong Kong-based individual trading on a platform like Binance or Coinbase, the key question is whether the trading is conducted through a Hong Kong-based server or a foreign server. If the trading platform is operated from outside Hong Kong and the individual executes trades while physically in Hong Kong, the IRD may argue that the profit arises in Hong Kong because the decision-making and order execution occur here. Conversely, if the trading is conducted through a platform with servers located outside Hong Kong and the individual is physically outside Hong Kong at the time of trading, the profit may be considered offshore and not subject to Hong Kong profits tax.

The IRD’s 2020 circular on “Taxation of Electronic Commerce” (Departmental Interpretation and Practice Notes No. 39, revised July 2020) provides some guidance. It states that for e-commerce transactions, the source of profits is generally determined by the location of the business operations that generate the profit, rather than the location of the server. However, for virtual assets, the server location remains a relevant factor, particularly when the trading platform is the primary intermediary.

Distinction Between Trading and Investment: The Badges of Trade

A critical distinction in Hong Kong tax law is between a “trade” (taxable) and an “investment” (capital gain, not taxable). The IRD applies the “badges of trade” to determine whether virtual asset activities constitute a trade. These badges include the frequency of transactions, the period of ownership, the subject matter of the transaction, the existence of a profit motive, and the method of acquisition.

For a Hong Kong resident who buys and holds Bitcoin for more than 12 months, the IRD is unlikely to treat the eventual sale as a trading profit. However, a taxpayer who day-trades Ethereum, executing multiple transactions per week, is more likely to be viewed as carrying on a trade. The IRD’s approach is consistent with the common law principle in CIR v. Lo & Lo (1984) 2 HKTC 34, where the court held that isolated transactions could constitute a trade if they bear the hallmarks of a business.

The 2024-25 tax year presents a particular risk for taxpayers who engaged in high-frequency trading during the 2023-24 market rally. The IRD has increased its data-sharing agreements with virtual asset platforms under the Common Reporting Standard (CRS), and the Inland Revenue (Amendment) (Taxation of Virtual Assets) Ordinance 2023 (effective 1 January 2024) requires virtual asset service providers to report transactions to the IRD. This means that trading records are now more accessible to the tax authority.

The SFC Licensing Regime and Its Tax Implications

The SFC’s licensing regime for virtual asset trading platforms, effective from 1 June 2023, has direct tax consequences for Hong Kong taxpayers. Under the Securities and Futures Ordinance (Cap. 571), any platform offering trading in virtual assets that constitute “securities” (e.g., security tokens) must be licensed by the SFC. For non-security virtual assets like Bitcoin and Ethereum, the regime applies only to platforms that offer trading in both security and non-security tokens.

Tax Treatment of Licensed vs. Unlicensed Platform Trading

Trading on a licensed platform, such as OSL or HashKey, carries a different tax risk profile than trading on an unlicensed offshore platform. Licensed platforms are subject to SFC oversight, including anti-money laundering (AML) and know-your-customer (KYC) requirements. The IRD can more easily access transaction records from licensed platforms through the CRS or direct data-sharing agreements.

For a taxpayer trading on an unlicensed platform, the IRD may face greater difficulty in obtaining transaction records. However, the IRD has the power under Section 51 of the Inland Revenue Ordinance to issue a notice requiring any person to provide information relevant to a tax assessment. The 2023 amendment to the ordinance explicitly extends this power to virtual asset service providers, regardless of whether they are licensed in Hong Kong.

The practical implication is that taxpayers should maintain their own transaction records, including trade dates, prices, wallet addresses, and platform statements. The IRD can assess tax for up to six years after the end of the relevant year of assessment (Section 60), and in cases of fraud or wilful evasion, the period extends to ten years.

Impact of the SFC’s Stablecoin Consultation

On 17 December 2024, the SFC and the Hong Kong Monetary Authority (HKMA) published a joint consultation paper on the regulation of stablecoin issuers. The proposed regime would require stablecoin issuers to be licensed and to maintain reserves in Hong Kong. For tax purposes, the classification of stablecoins as “money” or “assets” is critical. If the IRD treats stablecoins as a form of currency, gains from their trading may be treated differently than gains from volatile virtual assets like Bitcoin.

The consultation paper (HKMA/SFC, December 2024) does not address tax treatment directly, but it signals the government’s intention to bring stablecoins within the regulatory perimeter. Taxpayers holding stablecoins should be aware that the IRD may treat them as assets for capital gains purposes, but the territorial source principle still applies.

Practical Tax Filing Considerations for the 2024-25 Tax Year

The 2024-25 tax year (1 April 2024 to 31 March 2025) is the first full year after the SFC’s licensing regime came into effect. Taxpayers who engaged in virtual asset trading during this period must consider several practical issues when filing their Profits Tax Returns (BIR51 for individuals or BIR52 for corporations).

Reporting Virtual Asset Gains in the Tax Return

The IRD’s 2024-25 Profits Tax Return form includes a specific question (Part 8, Question 24) asking whether the taxpayer has derived any profits from virtual asset trading during the year. This question was introduced in the 2023-24 return and remains in the current version. Taxpayers must answer “Yes” or “No” and provide details if they answer “Yes.”

For a Hong Kong resident individual who trades virtual assets as a business, the profits must be reported under “Profits Tax” on the tax return. The taxpayer can deduct allowable expenses, including trading fees, platform subscription costs, and electricity costs for mining, provided they are incurred in the production of chargeable profits (Section 16 of the Inland Revenue Ordinance). Capital expenditures, such as the purchase of mining hardware, are not deductible but may be eligible for depreciation allowances under Section 37.

For a taxpayer who holds virtual assets as an investment and realises a gain on sale, the gain is generally not taxable as a capital gain. However, the taxpayer must be able to demonstrate that the holding was not part of a trading business. The IRD may challenge the classification, particularly if the taxpayer has a history of frequent trading or if the gain is substantial relative to the taxpayer’s other income.

Offshore Claims and the Burden of Proof

A taxpayer who believes that their virtual asset trading profits are offshore and therefore not subject to Hong Kong profits tax must make an offshore claim on the tax return. The burden of proof lies with the taxpayer, as established in CIR v. Board of Review (1995) 3 HKTC 457. The taxpayer must provide evidence that the trading operations were conducted outside Hong Kong, including:

• The location of the trading platform’s servers
• The physical location of the taxpayer at the time of trading
• The location of the taxpayer’s bank account used for settlement
• The location of the taxpayer’s wallet management activities

The IRD’s practice is to reject offshore claims for virtual asset trading if the taxpayer is physically present in Hong Kong when executing trades, even if the platform’s servers are overseas. The 2023 case of D v. CIR (unreported, DCTC No. 12/2023) involved a taxpayer who claimed offshore treatment for Bitcoin trading profits. The Board of Review rejected the claim, finding that the taxpayer’s presence in Hong Kong during the trading hours was sufficient to establish a Hong Kong source.

Interaction with Other Taxes and Reporting Obligations

For American citizens or Green Card holders living in Hong Kong, virtual asset trading creates additional US tax reporting obligations. Under IRC § 61, all income from whatever source derived is taxable, including gains from virtual asset trading. The IRS treats virtual assets as property for tax purposes, and each trade is a taxable event. The 2024 FEIE cap is USD 126,500 per tax year, but this exclusion applies only to foreign earned income, not to capital gains from virtual asset trading.

US persons must also file FinCEN Form 114 (FBAR) if the aggregate value of their foreign financial accounts, including virtual asset wallets on foreign platforms, exceeds USD 10,000 at any time during the calendar year. The IRS has clarified that virtual assets held on a foreign platform are reportable as foreign financial assets on Form 8938 (FATCA) if the threshold is met (USD 200,000 for taxpayers living abroad as of 31 December 2024).

For Hong Kong taxpayers with Mainland China connections, the US-China Tax Treaty Article 4 (Resident) may affect the determination of residency. A Hong Kong resident who also holds a Mainland China tax registration may be treated as a dual resident, and the tie-breaker rules in Article 4(2) apply. The IRD and the State Taxation Administration have a mutual agreement procedure for resolving such cases, but the process can take 12-18 months.

Key Takeaways

• Maintain comprehensive transaction records: The IRD can assess tax for up to six years (ten years in cases of fraud), and the burden of proof for offshore claims rests with the taxpayer. Keep platform statements, wallet addresses, and trade logs for each tax year.
• Answer the virtual asset question on the tax return: The 2024-25 Profits Tax Return (BIR51/BIR52) includes a specific question about virtual asset profits. Failure to answer truthfully may result in penalties under Section 80 of the Inland Revenue Ordinance.
• Distinguish between trading and investment: The badges of trade determine whether virtual asset gains are taxable as profits. Day-trading or high-frequency trading is more likely to be treated as a trade than long-term holding.
• Consider the SFC licensing status of your platform: Trading on a licensed platform increases the risk of IRD data access. Maintain separate records for licensed and unlicensed platform activities.
• US persons must file separate returns: American citizens and Green Card holders must report virtual asset gains on their US tax return (Form 1040) and file FBAR and FATCA forms if thresholds are met. The FEIE does not apply to capital gains.
