Thailand cryptocurrency tax guide

What this guide covers

This guide covers Thailand's approach to individual cryptocurrency capital gains taxation for the 2025 tax year, based on secondary reporting of a time-bound exemption introduced for 2025 through 2029. The Revenue Department's own site (rd.go.th) wasn't directly fetched in this research pass. This is educational information, not individualized tax advice.

Tax treatment of cryptocurrency

Thailand generally treats crypto gains as assessable income subject to personal income tax — but there's a major exception you should know about first. A specific exemption, running from January 1, 2025 through December 31, 2029, removes personal income tax on capital gains from selling cryptocurrency or digital tokens, provided the transaction takes place through a digital asset exchange, broker, or dealer licensed by Thailand's Securities and Exchange Commission (SEC). That licensed-platform condition is the central fact here: gains on unlicensed platforms or peer-to-peer transactions fall outside the exemption and stay taxable under ordinary rules.

Common taxable events

• Selling crypto through a platform not licensed by Thailand's SEC, or via peer-to-peer or other unlicensed channels — this stays subject to ordinary personal income tax, since the exemption doesn't apply.
• Mining rewards, staking rewards, and crypto received as payment for goods or services or as compensation — taxable income at the time of receipt. The 2025-2029 exemption is specifically for capital gains on sale through licensed platforms, not a general crypto-income exemption.

Potentially non-taxable events

• Capital gains from selling crypto or digital tokens through an SEC-licensed digital asset exchange, broker, or dealer, between January 1, 2025 and December 31, 2029 — exempt from personal income tax under this specific, time-bound measure.
• Buying and holding crypto without disposing of it isn't itself a taxable event.

Tax rates and thresholds

No personal income tax applies to a qualifying capital gain made through an SEC-licensed platform during the 2025-2029 exemption window. Gains or income falling outside that exemption — unlicensed-platform sales, mining, staking, payment-in-kind — are taxed under Thailand's ordinary progressive personal income tax rates, which this guide doesn't reproduce in full. Confirm current brackets on rd.go.th. This guide doesn't confirm whether a separate withholding-tax mechanism, sometimes discussed in earlier Thai crypto tax proposals, currently applies in addition to or instead of this framework.

Cost basis and calculation

For gains outside the exemption, the taxable amount is calculated using ordinary Thai personal income tax principles — proceeds less documented cost. This guide doesn't confirm a specific cost-basis identification method, such as FIFO, for crypto specifically.

Reporting and compliance

• Income or gains that fall outside the 2025-2029 exemption must be declared in the individual's annual personal income tax return (PND 90/91) filed with the Revenue Department.
• This guide doesn't confirm whether a qualifying exempt gain through a licensed platform must still be separately disclosed even though no tax is owed — confirm directly with the Revenue Department.

Residency and cross-border issues

Your Thai tax residency generally governs whether foreign-sourced income is taxable when remitted into Thailand, under Thailand's broader foreign-sourced-income rules, which have themselves evolved in recent years for other income types. This guide doesn't resolve how those general foreign-sourced-income rules interact with the crypto-specific exemption described above — that interaction wasn't confirmed in this research pass.

Example

This example is hypothetical, for illustration only. Niran sells crypto through an SEC-licensed Thai exchange in 2026 for a profit. Under the 2025-2029 exemption, that capital gain is exempt from personal income tax. Had Niran instead sold the same crypto through an unlicensed overseas platform or a private peer-to-peer deal, the gain would stay subject to ordinary personal income tax, since the exemption's licensed-platform condition wouldn't be met.

Limitations and review information

Tax year covered: 2025. Last verified: October 11, 2026. Known gap: rd.go.th wasn't directly fetched. This guide relies on consistent secondary legal reporting of Ministerial Regulation No. 399's exact number, gazette date, and effective dates, and doesn't confirm interaction with Thailand's general foreign-sourced-income remittance rules, whether a separate withholding mechanism applies, or whether the SEC-licensed-platform condition survived into the final gazetted text exactly as earlier reported. This is educational information only, not individualized tax advice — confirm current specifics directly with the Revenue Department or a qualified Thai tax professional.
