As Bitcoin and cryptocurrency adoption surges in Thailand, investors face crucial questions about tax compliance. Reporting Bitcoin gains correctly is essential to avoid penalties from the Revenue Department. This comprehensive guide breaks down Thailand’s cryptocurrency taxation rules, providing clear steps to calculate, declare, and pay taxes on your digital asset profits while highlighting common pitfalls.
Understanding Bitcoin Taxation in Thailand
Thailand’s Revenue Department treats cryptocurrency as a digital asset under the Emergency Decree on Digital Asset Taxation (2018). Key principles include:
- Taxable events: Selling Bitcoin for fiat currency, trading between cryptocurrencies, or using crypto for goods/services
- Non-taxable events: Buying Bitcoin with fiat, transferring between personal wallets, or holding without disposal
- Tax classification: Gains are typically taxed as either capital gains (for individual investors) or business income (for frequent traders)
- Tax rates: Progressive personal income tax rates from 0% to 35% based on annual income brackets
Step-by-Step Guide to Reporting Bitcoin Gains
- Track All Transactions
Record every buy/sell/trade with dates, amounts in THB (using exchange rates at transaction time), wallet addresses, and purpose. Use crypto tax software like Koinly or CoinTracking for accuracy. - Calculate Net Gains
Apply this formula for each disposal: (Selling Price – Purchase Cost – Allowable Expenses) = Taxable Gain. Use FIFO (First-In-First-Out) method unless specific identification is documented. - Classify Your Income
Determine if gains qualify as:- Capital gains: Occasional trading (add to ‘Other Income’ on tax return)
- Business income: Frequent/high-volume trading (requires corporate tax filing)
- File Tax Return
Submit Form P.N.D.90/91 by March 31st of the following year. Include crypto gains under Section 40(4)(i) for capital gains or Section 40(8) for business income. - Pay Taxes Due
Remit payments via bank transfer, Revenue Department offices, or online portals before the filing deadline to avoid 1.5% monthly penalties.
Common Reporting Mistakes to Avoid
- Ignoring small transactions: Even minor gains from crypto swaps or DeFi activities are taxable
- Poor record-keeping: Failing to document cost basis leads to overpayment
- Mixing personal/business wallets: Creates tracing difficulties during audits
- Omitting foreign exchange gains: THB conversion differences must be reported
- Forgetting loss deductions: Capital losses can offset gains for 5 years

Recent developments signal evolving regulations:
