2025 Taiwan Virtual Currency Taxation Ultimate Guide: Full Analysis of Over the Counter Trading, Regulations, and Tax Filing Procedures

After earning profits from virtual currency investments, have you started worrying about “whether I need to pay taxes” or “how to file my tax return”? As Taiwan cryptocurrency regulations become increasingly clear, understanding the relevant virtual currency taxation rules has become essential for every investor. In particular, frequent over the counter virtual currency trading (OTC) is more likely to attract attention from tax authorities. This article provides the most comprehensive virtual currency taxation guide, covering regulatory status, tax calculation, and filing procedures, helping you invest with confidence and legally reduce your tax burden. 📈

Current Status of Taiwan Virtual Currency Regulations: Do I Need to Pay Taxes?

Simply put: as long as there is a profit, you may need to pay taxes. Although Taiwan does not yet have a “specific tax law” for virtual currencies, this does not mean that gains from trading are tax exempt. Tax authorities classify such gains under the existing tax system, and the core issue depends on the source of your income and your identity.

Who Is the Competent Authority? Latest FSC Regulatory Scope Explained

The main regulatory authority for virtual currency in Taiwan is the Financial Supervisory Commission (FSC). Since July 2021, the FSC has officially included “virtual asset service providers” (VASP) within the scope of anti money laundering regulations. This means that although the FSC does not intervene directly in price fluctuations, it enforces strict requirements regarding platform operations, real name verification (KYC), and fund flows.

Recently, the FSC released the “Guidelines for the Management of Virtual Asset Platforms and Trading Businesses (VASP)”, strengthening regulations on transaction transparency, asset segregation, and customer protection. This also indicates that the government’s ability to monitor fund movements has increased, and investors must take tax reporting obligations more seriously. 

Legal Status of Virtual Currency in Taiwan: Money or Commodity?

This is a key question. At present, Taiwan’s Central Bank and the FSC do not recognize Bitcoin or other virtual currencies as “legal tender”. In legal and tax terms, they are more likely to be regarded as high risk digital “commodities” or “virtual assets”.

• Not currency: You cannot use it to pay taxes, fines, or conduct major statutory transactions.
• An asset/commodity: Therefore, the price difference generated from buying and selling this “commodity” constitutes “income” and must be taxed according to law.

Tax Classification: Personal Overseas Income vs. Domestic Business Income

After understanding that virtual currency is treated as a “commodity”, the next step is determining which type your trading gains fall under, as this directly affects tax rates and filing methods:

• Personal overseas income: This applies to the vast majority of Taiwan investors. If you trade through overseas exchanges (such as Binance or OKX), your gains are classified as “overseas income” for tax purposes. If your total overseas income exceeds TWD 1,000,000 in a given year, it must be included in your personal basic income calculation. If your total basic income exceeds TWD 6,700,000, you will be subject to a 20% basic tax amount (commonly known as the Alternative Minimum Tax).
• Domestic business income: If you trade virtual currencies frequently and in large amounts within Taiwan (especially as a P2P or OTC merchant), either under a company name or as an individual, and you do so as a business activity, tax authorities may classify you as a “profit-seeking enterprise”. In this case, you must pay a 5% business tax, and your gains must be included in profit-seeking enterprise income tax (20% rate) or calculated under the business income category of personal comprehensive income tax.

How Is Virtual Currency Taxed? From Domestic Trading to Over the Counter Transactions

After understanding tax classification, the next step is looking at the actual calculation methods. Different trading models come with different tax calculations and risks. Knowing how to calculate cryptocurrency trading income is the first step toward accurate tax filing.

Profits from Overseas Exchanges: How Do You Calculate Basic Income and File Taxes?

For individual investors, profits earned on overseas exchanges make up the majority of taxable cases. The calculation method is as follows:

Annual overseas income = Total annual overseas revenue − Total annual overseas cost

For example, if in 2024 your total sell amount on an overseas exchange is TWD 8,000,000 and your total purchase cost is TWD 6,000,000, then your annual overseas income is TWD 2,000,000.

Filing Procedure:

1. Determine Whether Filing Is Required: If overseas income does not reach NT$1 million, filing is not required.
2. Calculate the Basic Income Amount: Add overseas income (NT$2 million in this example) to other items that must be included in the basic income amount (such as specific insurance payouts, non-cash donations, etc.).
3. Determine Whether Tax Is Payable: If the total “basic income amount” exceeds the exemption threshold (currently NT$6.7 million), basic tax must be paid. The formula is: (Basic income amount – NT$6.7 million) x 20%.
4. Compare the Tax Amounts: If the calculated basic tax exceeds your “comprehensive income tax payable”, you must pay the difference.

Domestic Exchanges or Profit-Making: Business Tax and Corporate Income Tax Explained

If your trading activities are classified domestically as a “profit-seeking enterprise”, tax calculations become far more complex. This typically applies to OTC dealers, professional traders, or corporate entities.

• Business Tax: For each transaction, the price difference (profit) requires an invoice to be issued, and a 5% business tax must be paid.
• Corporate Income Tax: After deducting all costs and expenses from total annual profits, a 20% corporate income tax must be paid.

For example, if an OTC merchant buys and sells USDT within one month and earns a price difference profit of NT$100,000, they must pay NT$5,000 in business tax on that NT$100,000, and this profit will ultimately be included in the calculation base for annual corporate income tax.

Key Note: Tax Risks and Filing Methods for Over-the-Counter (OTC) Crypto Transactions

Over-the-counter (OTC) or P2P crypto transactions are popular due to their privacy and convenience, but they also come with extremely high tax and legal risks.

• Cash Flow Is Hard to Explain: Frequent large fiat deposits and withdrawals can easily be flagged by banks as abnormal transactions and may trigger anti-money-laundering investigations.
• High Tax Risk: Due to the lack of standardized exchange records, if you cannot provide complete cost evidence, tax authorities may directly classify the transaction as “income” during audits, requiring back taxes and penalties.
• Filing Method: Individuals engaging in OTC transactions who earn substantial profits are still advised to file in the same manner as overseas income. Be sure to retain all chat records, transfer receipts, and on-chain transaction IDs (TXID) to verify your fund sources and costs.

Step-by-Step Guide: Complete Tutorial for Filing Crypto Taxes

Once you understand the regulations and calculation methods, the actual filing process is not difficult. Below is a simplified procedure for the annual May tax season to help you complete your crypto tax filing. ✍️

Step 1: How Do You Organize and Calculate Your Annual Crypto Gains and Losses?

This is the most important and also the most tedious step. Accurate records are the foundation of lawful tax savings.

1. Export Transaction Records: Export a full annual transaction report (usually a CSV or Excel file) from the backend of every exchange you use (such as Binance, MAX, ACE, etc.).
2. Consolidate All Transactions: Combine records from different platforms into a single spreadsheet. The content should include the buy/sell date, token, quantity, price, and total amount (converted into TWD).
3. Calculate Costs and Income: Use the “first-in, first-out method” (FIFO) or the “weighted average method” to calculate your transaction costs. In simple terms, each sale is matched with the corresponding purchase cost to determine the profit or loss for each transaction.
4. Sum Up Annual Gains and Losses: Add all transaction gains and losses to determine your total annual profit or loss. You may also use third-party accounting software (such as Koinly or CoinTracker) to automate this process. 

Step 2: Required Documents and Online Filing System Instructions

After preparing your gains and losses worksheet, you can proceed to the filing stage.

• Required Documents:
  1. Annual gains and losses summary sheet.
  2. Original transaction records exported from each exchange.
  3. OTC transaction chat records, transfer records, and on-chain records.
• Online Filing:
  1. Log in to the Ministry of Finance e-Filing and Tax Payment Service website.
  2. Under “Income Categories”, locate the “Overseas Income” field under “Basic Income Amount”.
  3. Enter your calculated annual total profit in this field. The system will automatically determine whether basic tax is payable.

What If You Forget to File? Supplementary Filing Procedure and Penalty Explanation

If you forget to file due to unfamiliarity with the regulations, do not ignore it. Taking the initiative to file before the tax authority discovers it usually reduces penalties.

• Supplementary Filing Procedure: Submit a written application for supplementary filing to the branch office or tax collection office of the National Taxation Bureau in your registered household area and pay the outstanding tax.
• Related Penalties: If the tax authority discovers unreported or underreported overseas income, you may be required to pay the tax owed and a fine of up to twice the amount of the unpaid tax. If malicious tax evasion is involved, criminal liability may also apply.

Frequently Asked Questions (FAQ)

Q: Can crypto losses be used to offset taxes?

A: Under current regulations, losses from overseas property transactions can only be used to offset overseas property transaction income in the same year, and the offset amount cannot exceed that income. For example, if you earned NT$500,000 in overseas stock income this year and incurred NT$300,000 in overseas crypto losses, you may use the loss to offset the income, resulting in NT$200,000 in overseas income to be reported. However, if there is no other overseas property transaction income that year, the loss cannot be deducted and cannot be carried forward to future years.

Q: Do mining, staking, or airdrop income need to be reported for tax purposes?

A: Yes, all of these are considered income. For tax purposes, the “market price at the time” you receive the crypto is regarded as your cost (usually zero or very low). When you sell these tokens in the future, almost the entire sale amount will be treated as income. Therefore, it is recommended to record the token, quantity, and market price on the day you receive it for future cost reference.

Q: When conducting over-the-counter (OTC) crypto transactions, how do I keep transaction records for tax filing?

A: Keeping records for OTC transactions is crucial. It is recommended to create a dedicated folder and store the following information for each transaction: 1. Complete chat records with the counterparty (including confirmation of price, quantity, and payment method). 2. Screenshots of your fiat transfer or bank statements. 3. The on-chain transaction record (Transaction ID/Hash) showing the counterparty’s transfer to you. 4. The date and time of the transaction. The more complete the records, the more reassurance you will have during tax audits in the future.

Q: Are profits from NFT transactions also taxable?

A: Yes. NFTs (non-fungible tokens) are also classified as “virtual assets” for tax purposes. Therefore, the profit generated from buying and selling NFTs follows the same tax treatment principles as general virtual currency. If you trade through overseas platforms (such as OpenSea), the profit is considered overseas income. If you are a creator who continually issues NFTs and earns profit, it may be treated as business income.

Conclusion

In summary, as long as you generate profit from virtual currency transactions in Taiwan, you should proactively understand Taiwan’s cryptocurrency regulations and file your taxes honestly. As the regulatory framework becomes increasingly comprehensive, any flow of funds may leave a record. Whether you operate through overseas exchanges or engage in frequent over-the-counter crypto transactions, it is strongly recommended to keep complete and detailed transaction records. Although the specifics of crypto taxation remain unfamiliar to many, proactively developing bookkeeping habits and consulting a professional accountant when situations become complex is the best way to ensure you can enjoy your investment results with peace of mind.
