As the 2025 tax season approaches, more individuals involved in cryptocurrency trading are turning their attention to tax compliance. While Taiwan’s regulatory framework for virtual assets is still evolving, the current tax treatment of digital currencies is based on existing income tax laws. This guide breaks down everything you need to know about virtual currency taxation — from classification and reporting requirements to filing procedures and strategic tax-saving methods.
What Type of Income Is Crypto Gains Considered?
In Taiwan, virtual currencies like Bitcoin are generally treated not as legal tender but as virtual commodities, according to financial regulators. This classification means that profits from buying and selling crypto are viewed similarly to gains from selling digital goods in online games.

Under Article 14, Paragraph 1, Category 7 of the Income Tax Act, these profits fall under property transaction income. This is the primary category used when reporting crypto-related gains during annual tax filing.
However, a critical distinction arises based on trading frequency. If an individual engages in frequent trading — such as arbitrage or day trading — authorities may deem this activity as having a commercial nature. In such cases, the trader could be required to register for business operations and pay value-added tax (VAT) if monthly sales exceed NT$80,000.
When Do You Need to Pay Taxes on Crypto Gains?
Tax liability arises only when a taxable event occurs — specifically, when virtual currency is converted into fiat money (e.g., TWD or USD) and withdrawn to a personal bank account. This concept is known as "realization of gain or loss."
Simply holding crypto, even if its market value increases significantly, does not trigger taxation. Similarly, swapping one cryptocurrency for another (e.g., BTC to ETH) is not considered a realized gain under current interpretations.
Only upon conversion to fiat and withdrawal does the transaction become reportable for tax purposes.
Tax Implications: Withdrawing Crypto as TWD to a Local Bank Account
When you sell cryptocurrency on a local exchange like BitoPro, ACE, or MAX and transfer the proceeds in New Taiwan Dollars (TWD) to your domestic bank account, this income is typically classified as domestic-sourced income.
This type of gain must be reported under the Comprehensive Income Tax system. Since these platforms follow Know Your Customer (KYC) protocols, tax authorities can access transaction records under Article 30 of the Tax Collection Act if necessary.
It's important to note: even if your trades occur primarily on overseas exchanges, transferring funds through a Taiwanese exchange may still result in the income being treated as domestic unless you provide documentation proving otherwise.
Additionally, banks are required to report any single withdrawal exceeding NT$5 million to the Financial Supervisory Commission under anti-money laundering regulations. While this doesn’t directly involve tax reporting, it may draw regulatory attention.
Tax Implications: Receiving Crypto Proceeds in Foreign Currency via Wire Transfer
If you convert cryptocurrency to USD on an international exchange and receive the funds via wire transfer (telegraphic transfer) into a foreign currency account in Taiwan, this income is generally treated as overseas-sourced income.
To ensure proper classification during tax season:
- Declare the remittance purpose as "268 - Sale of Overseas Virtual Assets" when releasing funds at your bank.
- Retain proof of transaction, including exchange statements and wire confirmation.
While overseas income isn't included in standard Comprehensive Income Tax calculations, it may affect your liability under the Minimum Tax Liability System (Basic Income Tax).
Under this system:
- Individuals with annual overseas income exceeding NT$1 million must report it.
- A total deduction of NT$6.7 million applies across seven categories of basic income.
- After deductions, taxable basic income is taxed at 20%.
- You only pay the difference if your calculated basic tax exceeds your regular comprehensive income tax.
For example:
If your comprehensive tax liability is NT$5 million and your basic tax comes to NT$4 million, no additional payment is due.
Careful planning is essential — especially if you have other forms of high-value income — to maximize use of the NT$6.7 million deduction threshold.
Does the Tax Filing System Automatically Include Crypto Income?
Currently, most local cryptocurrency exchanges are not required to submit users’ annual transaction data to tax authorities. As a result, the e-filing system will not auto-populate crypto gains.
However, this does not mean crypto profits are tax-exempt. The Ministry of Finance clearly states that all virtual asset gains must be manually declared by taxpayers.
Failure to report could lead to penalties if discrepancies are later discovered during audits.

Is There a Tax Liability If I Convert Crypto to TWD but Don’t Withdraw?
No — not yet.
Funds held within a local exchange (even after converting crypto to TWD) remain in a trust account managed by the platform, not your personal bank account. Therefore, no gain has been "realized" until the money is transferred out.
Until withdrawal occurs, there is no taxable event, and thus no obligation to report or pay taxes.
This provides strategic flexibility: traders can time their withdrawals to align with favorable tax planning windows.
Can Losses from FTX Bankruptcy Be Claimed for Tax Relief?
Unfortunately, not currently — because the loss has not been "realized."
According to a Ministry of Finance announcement, investors affected by FTX's collapse may prepare documentation of their original investment costs. However, since assets remain frozen and cannot be sold, the loss is considered unrealized.
Only realized losses — where assets were sold or disposed of at a loss — qualify for deduction against capital gains.
Once FTX users recover partial value or receive distribution through bankruptcy proceedings, any resulting shortfall compared to original cost basis may then be recognized as a deductible loss.
Can Other Crypto Trading Losses Be Used to Offset Taxes?
Yes — but with conditions.
Realized crypto losses can be claimed as a special deduction under "property transaction losses," reducing your overall taxable capital gains.
Key rules:
- Must provide verifiable records (trade history, wallet transfers, exchange statements).
- Losses can offset gains in the same year.
- Unused losses can be carried forward for up to three subsequent years.
- Cannot offset salary or other non-capital income.
Note: Overseas crypto losses cannot be offset against domestic gains. They can only reduce overseas gains in the same year and cannot be carried forward beyond that scope.
Step-by-Step Guide: How to File Crypto Taxes
✅ Reporting Domestic Property Transaction Income
- Log in to the Comprehensive Income Tax E-Filing System.
- In Step 2 ("Enter Income"), add a new entry.
- Select:
"Property Transaction Income (Non-Residential – Cost Not Provable)"
(Most common choice when cost basis documentation is incomplete)
Even if you have proof of cost, many filers use this category due to lack of automated integration with exchanges.
✅ Claiming Domestic Property Transaction Losses
- Navigate to Step 3 ("Special Deductions").
Under "Amend Property Transaction Loss Details," submit:
- Date of transaction
- Asset description
- Sale price
- Original cost
- Supporting documents
Losses reduce taxable gains dollar-for-dollar within limits.
✅ Reporting Overseas Property Gains or Losses
- Go to Step 4 ("Basic Tax Calculation").
Add new entry:
- Category: Overseas Income
- Type: 76 – Property Transaction Income
- Enter income amount and allowable costs/losses on the same form.
Remember: Overseas losses are strictly limited in deductibility and timing.
Smart Tax-Saving Strategies for Crypto Traders
- Delay Withdrawals: Keep profits in exchange wallets until withdrawal is necessary. No realization = no tax trigger.
- Split Large Withdrawals: For recurring income needs, withdraw less than NT$80,000 per month to avoid potential VAT registration.
- Use Wire Transfers for Large Amounts: Transferring USD via telegraphic transfer helps classify income as overseas, potentially qualifying for higher deductions under minimum tax rules.
- Maintain Accurate Records: Track purchase dates, prices, fees, and sale details across all platforms.
- Time Realizations Strategically: Realize gains or losses near year-end to optimize carryforward benefits.
Frequently Asked Questions (FAQ)
