Understanding Crypto Taxation in Thailand
Reporting cryptocurrency income is mandatory for Thai residents under the Revenue Department’s regulations. Since 2022, Thailand treats crypto as a taxable asset, meaning profits from trading, mining, or staking must be declared. The legal basis stems from Section 40 of the Revenue Code, which categorizes crypto gains as assessable income. Failure to comply can lead to audits, penalties, or legal action.
Types of Crypto Income Subject to Tax
Thai tax authorities recognize several crypto-related activities as taxable events:
- Trading profits: Gains from selling crypto at higher prices than purchase cost
- Mining rewards: Value of coins received from mining operations
- Staking/yield farming: Earnings from DeFi protocols or proof-of-stake networks
- Airdrops and forks: Free tokens received through distributions
- Crypto payments: Income from goods/services paid in cryptocurrency
Note: Personal transfers between your own wallets aren’t taxed, but conversions to fiat currency trigger tax obligations.
Step-by-Step Guide to Reporting Crypto Income
- Calculate your net gain: Subtract acquisition costs (purchase price + fees) from disposal value. Use FIFO (First-In-First-Out) method for cost basis calculation.
- Determine tax rate: Crypto profits are taxed as personal income at progressive rates from 0% to 35%, based on your total annual income bracket.
- File via P.N.D.90 or P.N.D.91: Use Form P.N.D.90 for individuals with business income, or P.N.D.91 for employment income. Declare crypto earnings under “Other Income” (Section 40(8)).
- Submit by March 31: Annual tax filing deadline for the previous calendar year. Extensions may apply for e-filing.
- Pay owed taxes: Settle liabilities within September following the tax year to avoid penalties.
Required Documents and Records
- Transaction history from exchanges (Binance, Bitkub, etc.)
- Wallet addresses and transfer proofs
- Receipts for hardware/operational costs (for miners)
- Bank statements showing fiat conversions
- Digital copies of Form P.N.D.90/91 submissions
Retain records for 5 years as the Revenue Department may audit past filings.
Common Mistakes to Avoid
- Ignoring small transactions – all gains are taxable regardless of amount
- Mixing personal and business crypto wallets
- Forgetting to report losses (which can offset gains)
- Using wrong cost-basis calculation methods
- Missing deadlines for quarterly payments if crypto is primary income source
Penalties for Non-Compliance
Failure to report crypto income may result in:
- 1.5% monthly penalty on unpaid taxes
- 100% surcharge on evaded amounts
- Criminal charges for severe cases (up to 7 years imprisonment)
- Asset freezing through the Anti-Money Laundering Office (AMLO)
Voluntary disclosure before audits typically reduces penalties by 50%.
Frequently Asked Questions (FAQ)
Q: Is cryptocurrency legal in Thailand?
A: Yes, but exchanges must be licensed by Thailand’s SEC. Trading is legal with tax obligations.
Q: Do I pay tax if I hold crypto without selling?
A: No – only realized gains (converted to fiat or used for purchases) are taxable. Unrealized gains aren’t taxed.
Q: How are losses handled?
A: Capital losses can offset crypto gains in the same tax year. Unused losses carry forward up to 5 years.
Q: What if I use international exchanges?
A: You still must report income. Provide translated transaction records if audited.
Q: Are NFTs taxable?
A: Yes – NFT sales profits follow the same capital gains rules as cryptocurrency.
Q: Can I deduct crypto investment expenses?
A: Only for business-related activities (e.g., mining electricity costs). Personal trading fees aren’t deductible.
