Crypto Taxation in Thailand

Thailand's approach to cryptocurrency taxation has shifted materially since 2022 and again in 2025. The base framework treats gains from digital-asset disposals as assessable income under the Revenue Code, subject to the same progressive personal income tax (PIT) rates that apply to other income categories. However, a five-year exemption for capital gains realised through SEC-licensed platforms, a permanent VAT exemption for licensed-exchange transactions, and a 2024 change to how foreign-source income is taxed all interact in ways that practitioners and individual investors must understand together.

What personal income tax rates apply to crypto gains in Thailand?

Thailand's Revenue Code, amended by the Emergency Decree B.E. 2561 (2018), classifies crypto income under Section 40(4): specifically sub-clause (h) for profit-sharing or benefit from holding digital tokens, and sub-clause (i) for the benefit derived from the transfer of cryptocurrency or digital tokens exceeding the investor's cost of investment. Both are assessable income subject to the standard progressive PIT schedule. The brackets, which have remained stable since 2013, are as follows:

Crypto gains are aggregated with other assessable income in the same tax year before applying the brackets. A 15% withholding tax applies to Section 40(4)(h) and 40(4)(i) income under Section 50(2)(f) of the Revenue Code; however, the Revenue Department has accepted that anonymous order-matched trades on SEC-licensed exchanges cannot be withheld at source in practice, so the withholding does not function as a final tax for most exchange-based traders -- annual PIT filing via PND.90 or PND.91 remains required.

Cost basis is tracked using either first-in-first-out (FIFO) or moving average cost. The chosen method must be applied consistently throughout the tax year and per asset type. Capital losses realised on SEC-licensed venues in the same tax year may offset capital gains under Ministerial Regulation No. 380; losses cannot be carried forward.

What is the 2025-2029 licensed-exchange capital gains exemption?

Ministerial Regulation No. 399 (B.E. 2568), published in the Royal Gazette on 5 September 2025 and effective retroactively from 1 January 2025, grants individual taxpayers a personal income tax exemption on capital gains derived from the sale or transfer of cryptocurrency or digital tokens, provided the transaction is executed through a digital asset business operator licensed by the Securities and Exchange Commission (SEC) of Thailand -- specifically a licensed Digital Asset Exchange, Digital Asset Broker, or Digital Asset Dealer. The exemption window runs from 1 January 2025 to 31 December 2029.

The policy rationale stated in the Cabinet approval (17 June 2025) is to stimulate the Thai digital asset market and position Thailand as a global digital asset hub. Only individual (natural person) investors qualify; companies trading digital assets remain subject to corporate income tax at 20% and are not eligible.

The exemption applies automatically to qualifying transactions -- no prior application or registration is required. However, investors must retain acquisition records, disposal documentation, trade confirmations, and cost-basis substantiation because the Revenue Department may audit the factual conditions of the exemption (i.e., whether the platform was in fact SEC-licensed at the time of the trade).

Critically, the following income categories remain fully taxable under the standard progressive PIT schedule even during the 2025-2029 window: mining proceeds, staking rewards, airdrop income, yield-farming and DeFi protocol returns, profits from unlicensed or peer-to-peer transactions, and gains realised on foreign (non-Thai-SEC-licensed) exchanges. For those categories, gains are assessable income aggregated with all other PIT income.

How does the VAT exemption work for crypto transactions?

Separate from the PIT exemption, trades of cryptocurrency and digital tokens executed through SEC-licensed exchanges, brokers, and dealers have been exempt from the standard 7% VAT since 1 April 2022 (originally under Royal Decree No. 744, extended under Royal Decree No. 779 in 2023, and made permanent under Royal Decree No. 788 in 2024). The VAT exemption covers secondary-market transfers by both individuals and juristic persons. OTC trades and transactions on unlicensed platforms remain technically within the general VAT framework, though enforcement against small-scale retail P2P activity has been limited in practice.

How does Thailand tax foreign-source crypto income?

Prior to 2024, Thai-resident individuals could avoid Thai PIT on foreign-source income by not remitting it to Thailand in the same calendar year it was earned -- a rule that allowed offshore crypto gains to be held abroad indefinitely without Thai liability. Departmental Instruction No. Por. 161/2566, issued by the Director-General of the Revenue Department on 15 September 2023 and effective from 1 January 2024, changed this fundamentally.

Under the revised rule, foreign-source assessable income (including crypto gains realised on non-Thai-licensed exchanges, staking rewards from foreign protocols, and mining income from offshore operations) earned from 1 January 2024 onwards is taxable in Thailand in the year the funds are remitted into Thailand, regardless of how many years later that remittance occurs. Income earned before 1 January 2024 and not yet remitted remains permanently exempt -- the Revenue Department confirmed this via Departmental Instruction No. Por. 162/2566 issued 20 November 2023.

Practical implications for crypto holders: a Thai resident who sold Bitcoin on a non-Thai exchange in 2024 and holds the proceeds in a foreign bank or crypto wallet will trigger Thai PIT on remittance when those funds are brought into Thailand -- whether by bank wire, e-banking transfer, or physically carrying cash across the border. Spending from a foreign crypto wallet via a debit card while physically in Thailand is an area where official guidance remains incomplete as of 2026; practitioners generally treat card-based foreign-currency spending as a remittance for conservatism. The 2025-2029 Ministerial Regulation No. 399 exemption does not apply to foreign-source income; it covers only gains on trades executed through Thai SEC-licensed platforms.

Double-tax agreement (DTA) relief may be available where the source jurisdiction has also taxed the same gain. Thailand has DTAs with over 60 countries. Crypto-specific treaty interpretation varies and practitioners should verify the applicable treaty article before claiming a foreign tax credit.

What compliance obligations apply for crypto filers in Thailand?

Individual Thai-resident investors file annual personal income tax returns on PND.90 (mixed income) or PND.91 (employment income plus other categories). The paper deadline is 31 March following the tax year; e-filing extends to 8 April. SEC-licensed exchanges are required to provide annual transaction summaries (typically CSV exports with timestamps, asset types, transaction sides, THB-equivalent prices, fees, and net consideration) which serve as primary supporting documentation.

Five-year record retention is required under Section 87 of the Revenue Code. Non-compliance carries a surcharge of up to 200% of any underpayment plus interest at 1.5% per month under Section 27, and wilful evasion carries criminal liability under Section 37. Where material foreign-source positions are involved -- multi-exchange records, DeFi protocol interactions, or cross-border remittances -- taxpayers typically engage a credentialed Thai tax practitioner to coordinate cost-basis consolidation and treaty-credit substantiation. Practitioners listed in the Thailand country overview can assist with multi-source crypto filing requirements.
