Taiwan Crypto Tax Guide 2026: Reporting Scenarios, Records, Overseas Income, and Common Mistakes

Last fact-checked: October 6, 2026. Laws, tax rules, and platform policies can change; confirm with the regulator or official notice.

Short Answer: The Key Question Is the Nature of Income

Taiwan's Ministry of Finance has published guidance related to virtual asset gains and losses in the context of the FTX event. The explanation states that an individual's gains from non-recurring domestic trading of virtual assets are property transaction income under Income Tax Act Article 14, paragraph 1, category 7. Individual income tax in Taiwan is territorial, so overseas income may instead involve the Income Basic Tax Act (alternative minimum tax). Corporate taxpayers can face different treatment under business income tax rules.

The Ministry has also described the calculation direction. Non-recurring domestic personal virtual asset gains may be treated as property transaction income, calculated from proceeds minus cost and fees. For domestic businesses, sales or exchanges of virtual assets are calculated by subtracting related costs and expenses from revenue. Either way, you need evidence of cost and fees.

This means the practical question is not simply whether crypto is taxable. You need to document:

Whether you are an individual, company, business, or custodian.
Where the transaction occurred and where the platform or counterparty sits.
Whether the income came from trading gains, mining, staking, airdrops, salary, services, or another source.
Whether you can prove cost basis, fees, exchange rates, and transaction history.
Whether overseas income and annual basic-income thresholds are relevant.

Common Scenario Table

Scenario	Possible Tax Direction	Records to Keep
Individual trades on Taiwan exchange	May involve property transaction income	Trade history, cost basis, fees, TWD deposits and withdrawals
Individual trades on overseas exchange	May involve overseas income analysis	Platform reports, fund flows, FX rates, location facts
Company account trades crypto	May involve business income tax	Accounting records, statements, valuation method, internal controls
Mining, node, or staking rewards	Income type requires case analysis	Reward time, token, amount, market value, cost
Airdrops, tasks, referral rewards	Not always simple capital gains	Campaign terms, receipt records, value at receipt
DeFi swaps or liquidity mining	High transaction count and complex basis	Wallet addresses, TxIDs, contract interactions, price source
Scam or platform collapse loss	Deductibility depends on evidence and rules	Police report, platform notice, transaction records, loss evidence

This table is not a filing conclusion. Facts and evidence decide the result.

What Records to Keep: Trade History Alone Is Not Enough

Many users remember sale proceeds but not acquisition cost. At minimum, you should be able to answer:

When you bought, how much you bought, and what asset or fiat you used.
Which fees, FX rates, and gas costs are part of the cost.
When you sold, how much you sold, and what asset you received.
Whether swaps, transfers, staking, rewards, or airdrops occurred in between.
Whether platform reports, bank records, and on-chain TxIDs can cross-check the story.

This applies even if you only buy and hold. You still need acquisition cost evidence for future disposals.

Records are not only for tax. The FTX case shows they also matter for disputes, insolvency, and loss documentation.

A Monthly Record-Keeping Routine

Do not wait until filing season. Platforms can change their interface, lock accounts, or shut down, and missing data is hard to rebuild later. Once a month:

Export spot, convert, earn, deposit, and withdrawal history from every exchange as CSV or PDF, and keep the original files.
For each wallet transfer, save the TxID, network, address, amount, time, and purpose of the transfer.
Consolidate into one spreadsheet with at least: date, platform, asset, cost, proceeds, fees, and notes.
Store exchange emails, KYC notices, freeze notices, and support ticket screenshots in the same folder.
Back up the whole set.

You do not need a screenshot of every trade. Exports cover routine activity. Take screenshots of large transfers, abnormal deposits or withdrawals, and support disputes. Screenshots alone, without exports, are not enough.

FIFO, Weighted Average, and Specific Identification

Crypto platforms do not always provide tax reports like securities brokers. Discuss the appropriate cost method with a tax professional and apply it consistently. Common approaches include:

Specific identification: matches disposed units to specific acquisition lots, requiring strong records.
FIFO: assumes earliest acquired assets are disposed first.
Weighted average: averages cost across holdings and can be useful for many small trades.

The goal is not to switch methods for the best result after the fact. The goal is to use a defensible method supported by data.

Overseas Income Is Not Only About the App's Country

Many Taiwan users trade on overseas exchanges. Overseas income analysis is not solved by the app language or brand name. You may need to document fund source, transaction location, counterparty, platform, banking route, and annual income totals. Ministry of Finance materials indicate that overseas income above certain amounts may be included in basic income calculations. Thresholds and rules can change, so verify current-year official sources before filing.

Practical workflow:

Separate local and overseas platforms in your ledger.
Store exchange reports, bank flows, and on-chain TxIDs separately.
Calculate annual gains and losses from transaction history, not only dashboard net worth.
If amounts are large, transactions complex, or company funds involved, consult a CPA or tax lawyer early.

If an overseas exchange export is incomplete, export whatever is available, then fill the gaps with bank records, TxIDs, emails, and screenshots, and note what is missing in your spreadsheet.

Scam Losses, FTX-Type Events, and Collapsed Platforms

A platform collapse, scam, theft, or frozen withdrawal does not automatically create a deductible tax loss. You need evidence of the event, fund flow, loss timing, recovery status, and legal treatment. The Ministry of Finance FTX explanation distinguishes individual and business treatment and notes limits around property transaction losses.

Save:

Platform suspension or bankruptcy notices.
Account balance screenshots and exported reports.
Deposit, withdrawal, trade, and transfer records.
Police reports, legal letters, or creditor claim records.
Bank or on-chain evidence proving cost and loss.

2026 Pre-Filing Checklist

Export CSV files from every exchange, not just annual summaries.
List all wallet addresses and major TxIDs, with each transfer's purpose labeled.
Collect TWD deposits, withdrawals, and bank statements.
Separate spot trades, futures, staking, airdrops, referral rewards, and DeFi.
Mark local and overseas platforms.
Document the cost-basis method used.
Store fee, gas, and exchange-rate sources.
For large losses, save police reports or platform event evidence.
For complex years, contact a professional before the filing deadline.
Follow Ministry of Finance, tax authority, and professional advice over blog summaries.

Common Mistakes

Assuming no TWD withdrawal means no records are needed.
Keeping only screenshots instead of CSV or PDF exports.
Treating transfers as sales, or missing swaps.
Not recording fiat value at the time of crypto-to-crypto swaps.
Withdrawing to self-custody without labeling the purpose.
Forgetting fees, gas, and FX effects.
Ignoring overseas exchange activity.
Having no police report or evidence for scam losses.
Treating online articles as formal tax opinions.

FAQ

Q: If I never converted crypto back to TWD, do I still need to care?

A: Do not assume no. Income type, transaction location, platform, fund flow, and annual totals can matter. No TWD withdrawal does not eliminate the need for records.

Q: Do I need records if I only buy and hold?

A: Yes. Unrealized gains are usually not the realized income you calculate, but you still need acquisition cost evidence for future disposals.

Q: What if the exchange does not provide a tax form?

A: Keep your own records. Export CSV files, save bank records and TxIDs, and consult a professional if needed.

Q: What if an overseas exchange export is incomplete?

A: Export whatever is available, then supplement it with bank records, TxIDs, emails, screenshots, and notes on the gaps.

Q: Do I need screenshots for every trade?

A: Not every trade. Keep exports for routine trades, and screenshot large transfers, abnormal deposits or withdrawals, and support disputes.

Q: Can scam losses offset tax?

A: Not automatically. Deductibility depends on income type, evidence, law, and facts. Preserve evidence, report the case, and seek tax advice.

Q: I only made small trades. Should I still keep records?

A: Yes. Small balances are the cheapest time to build the habit. Reconstructing data later is much harder.
