Taxation and Audit Challenges in Cryptocurrency Transactions

·

The rapid growth and increasing mainstream adoption of virtual currencies have made the question of whether and how they should be taxed a critical issue for tax authorities and individuals alike. With geopolitical events—such as the devaluation of the Russian ruble during the Ukraine conflict—driving more people toward assets like Bitcoin and USDT, the functional role of digital currencies in global finance can no longer be ignored.

Parallel to this trend, new digital asset classes like NFTs (Non-Fungible Tokens) have emerged, further complicating the regulatory and taxation landscape. While Taiwan’s Financial Supervisory Commission (FSC) introduced the Virtual Currency Platforms and Transactions Anti-Money Laundering and Counter-Terrorist Financing Measures on June 30, 2021, formal tax guidance remains limited. Although Security Token Offerings (STOs) are regulated as financial products, no legally issued security tokens currently exist in Taiwan. Meanwhile, payment tokens (e.g., Bitcoin, Ethereum) and utility tokens (e.g., loyalty points) remain largely unregulated, creating ambiguity around tax treatment—even if they are broadly considered taxable property.

This article explores the taxation framework for cryptocurrency transactions in Taiwan, focusing on three primary transaction types: crypto-to-crypto, crypto-to-NFT, and fiat-to-crypto exchanges. We’ll examine current legal interpretations, practical enforcement challenges, and compliance strategies.


Crypto-to-Crypto Transactions: The Taxation Dilemma

One of the most common forms of digital asset activity is trading one cryptocurrency for another—commonly known as "coin-to-coin" trading. For instance, a user might exchange Bitcoin for USDT or use Ethereum to purchase another altcoin.

If virtual currencies were treated as legal tender, such trades could resemble foreign exchange transactions. However, current judicial practice in Taiwan—including the Taiwan High Court's 107th Annual Jin Appeal No. 83 ruling—classifies cryptocurrencies not as currency but as crypto-assets or digital commodities. This means that exchanging one crypto asset for another constitutes a barter transaction, falling under Article 14, Paragraph 1, Category 7 of the Income Tax Act: property transaction income.

According to this provision:

"Where property or rights are acquired at cost, the amount by which the transaction value exceeds the original acquisition cost and all expenses related to acquisition, improvement, and transfer shall be treated as taxable income."

For example, if a taxpayer purchases Bitcoin for NT$100,000 and later uses it to acquire USDT worth NT$200,000, the NT$100,000 difference is considered taxable income.

However, real-world application presents significant hurdles:

These factors make enforcement extremely challenging. Without reliable data sources, tax authorities struggle to verify transaction values or even detect taxable events.


Crypto-to-NFT Transactions: New Frontiers in Digital Taxation

Non-Fungible Tokens (NFTs) represent another rapidly growing segment of the digital economy. Unlike fungible cryptocurrencies (where each unit is identical), each NFT is unique—often representing digital art, collectibles, or access rights.

When a taxpayer uses cryptocurrency (e.g., Ethereum) to purchase an NFT, this again constitutes a property exchange. Under current interpretation, both the disposal of crypto and the acquisition of the NFT trigger potential tax implications. Specifically:

Take the case of artist Chen Ling-Jiu’s “YOLO Cat” NFT collection. Buyers received not just digital artwork but also benefits such as:

Such hybrid characteristics blur the line between collectibles and securities. While Taiwan does not currently classify non-STO tokens as securities, income derived from royalty distributions could arguably fall under Category 1: Business Income of the Income Tax Act if structured as profit-sharing agreements.

Yet enforcement remains problematic:

International approaches vary: The U.S. IRS treats crypto transactions similarly to capital assets, applying capital gains tax (20%) or a higher 28% rate for collectibles. Taiwan lacks such a distinction and continues to treat all such gains under general property transaction rules—without specific exemptions or special rates.


Fiat-to-Crypto Transactions: The Entry and Exit Points

Converting fiat currency (like TWD or USD) into cryptocurrency—and vice versa—is typically the most traceable type of transaction. When users buy crypto using bank transfers through regulated exchanges, financial institutions may flag large transactions under anti-money laundering (AML) rules.

Selling crypto for fiat triggers a clear taxable event. The gain is calculated as:

Sale Proceeds (in TWD) – Acquisition Cost (in TWD) – Transaction Fees = Taxable Gain

But even here, complications arise:

Without comprehensive record-keeping tools, taxpayers risk underreporting—or overpaying due to conservative estimates.


Frequently Asked Questions (FAQ)

Q: Are cryptocurrency gains taxed in Taiwan?
A: Yes. Gains from selling or exchanging cryptocurrencies are generally treated as property transaction income under Article 14 of the Income Tax Act.

Q: Do I need to report every crypto-to-crypto trade?
A: Yes. Each trade is considered a disposal of one asset and acquisition of another, potentially triggering a taxable gain or loss.

Q: How should I value my crypto transactions if there’s no official exchange rate?
A: Use a reputable exchange rate from a major platform at the time of transaction. Consistency across reporting periods is key.

Q: Are NFTs taxed differently than regular cryptocurrencies?
A: Not explicitly in Taiwan. Both are treated as property, though NFTs with investment features may trigger additional income classifications.

Q: What records should I keep for tax purposes?
A: Maintain logs of transaction dates, types, amounts in crypto and TWD equivalents, wallet addresses, exchange records, and cost bases.

Q: Can tax authorities track my crypto transactions?
A: Increasingly yes—especially on centralized exchanges that comply with AML/KYC rules. Decentralized transactions are harder to trace but not immune to future regulation.


Conclusion: Toward a Clearer Framework

While Taiwan has taken steps toward regulating virtual currency platforms through AML frameworks, comprehensive tax guidelines remain underdeveloped. The absence of standardized valuation methods, reporting obligations, and enforcement mechanisms creates uncertainty for taxpayers and compliance risks for authorities.

As digital assets evolve—from simple payment tools to complex financial instruments—the need for updated tax policies becomes urgent. Until then, individuals must proactively maintain detailed records and seek professional advice to navigate this gray area responsibly.
