Crypto Tax in Thailand 2026: 15% Rate, Forms & Deadlines

Taxation of cryptocurrencies in Thailand

In Thailand, capital gains on cryptocurrencies are subject to tax. The calculation method used is FIFO with a rate of 15%. Understanding these rules is essential to stay compliant with tax legislation.

The FIFO method explained in detail

The First-In-First-Out (FIFO) method considers that the first assets purchased are the first sold. The gain is calculated on the difference between the sale price and the purchase price of the oldest lot.

Taxable events

In Thailand, private investors' crypto gains are generally exempt from income tax.

• ●Crypto-to-crypto exchange (in some countries only)
• ●Transfer between your own wallets
• ●Holding (HODL): holding without selling does not create any tax obligation (except in the Netherlands, Box 3)

Tax declaration procedure in Thailand

You must declare your crypto capital gains on the following forms: PND 90/91. We recommend keeping the complete history of your transactions as proof.

Exemption thresholds and allowances

In Thailand, there is currently no specific exemption threshold for crypto capital gains. This means that any capital gain, however small, is theoretically taxable. It is therefore important to declare all of your gains.

Deadlines and tax calendar

Each EU country has its own tax filing deadlines. In Thailand, the income tax return (including crypto capital gains) must generally be filed between April and June of the following year. We strongly recommend preparing your crypto tax return in advance with Taxes Crypto rather than waiting until the last moment.

Penalties for non-declaration

Failing to declare your crypto capital gains can lead to significant penalties: tax surcharges (10% to 40%), late-payment interest, and in serious cases, criminal prosecution for tax fraud. With DAC8 (2026), Binance automatically transmits your data to tax authorities, making detection of non-filers virtually automatic.

Tax treatment of crypto-to-crypto exchanges

In Thailand, a crypto-to-crypto swap (e.g. BTC → ETH) is a taxable event: the gain is computed at each swap, even without converting to fiat. Every transaction must therefore be tracked and valued.

NFTs, DeFi and derivatives

In Thailand, NFTs are generally treated like other crypto-assets: selling at a gain is taxable under the applicable regime (15%). DeFi income (staking, lending, yield farming) and derivatives (futures, options) are also taxable, each under its own regime. Regularly creating or selling NFTs may qualify as a professional activity.

Obligation to declare crypto accounts and wallets

In Thailand, check your obligations to report digital-asset accounts held abroad. International information-exchange standards (the OECD's CARF) are being rolled out gradually.

Practical calculation examples in Thailand

In Thailand, a crypto gain realised by a private individual — say 350,000 ฿ — is generally not taxed. The exemption covers private wealth management, outside any professional activity.

Tax calendar and key dates in Thailand

In Thailand, your crypto gains are usually filed by March for the previous year, via PND 90/91. Gather your statements early to meet this deadline.

Specific tips for Thailand

Crypto taxation in Thailand has certain specificities that are important to know. The FIFO calculation method imposes a precise logic for determining the order of disposals. Investors should be particularly vigilant about the following: crypto-to-crypto exchanges may be taxable depending on the jurisdiction, airdrops and hard forks have specific tax treatment, and staking or mining income is generally considered taxable income upon receipt. In case of a change of tax residence, the rules of your new country apply for future transactions, but unrealised gains may be subject to an exit tax in certain cases. Consult a tax professional if your situation is complex.
