Thailand taxes residents on cryptocurrency and digital asset income under a layered framework that combines the Revenue Code, the Emergency Decree on Digital Asset Businesses B.E. 2561 (2018), Royal Decrees, and Ministerial Regulations issued by the Ministry of Finance. Recent reform has materially reduced the personal income tax burden on individual traders. Ministerial Regulation No. 399 (B.E. 2568), gazetted on 5 September 2025, exempts capital gains realised on Thai Securities and Exchange Commission-licensed (SEC-licensed) venues from personal income tax for the period 1 January 2025 to 31 December 2029. The exemption sits alongside long-standing rules on the 15% withholding tax, the deductibility of capital losses, and the source-of-income rules that determine how foreign-sourced crypto gains are taxed when remitted to Thailand. This guide sets out exactly how each rule fits together for residents, foreign investors, and the digital asset operators they trade through.
Legal Framework Governing Cryptocurrency Income Tax in Thailand
Thailand's regulatory approach to digital assets developed in two parallel tracks from 2018 onward. The first track regulates who may operate a digital asset business; the second track defines how income from holding or transferring digital assets is taxed. Both tracks were created in May 2018 and have been refined repeatedly since.
Key Statutes and Regulations
| Instrument | Date in Force | Subject Matter |
|---|---|---|
| Emergency Decree on Digital Asset Businesses B.E. 2561 (2018) | 14 May 2018 | Establishes the SEC licensing regime for digital asset exchanges, brokers, dealers, fund managers, advisors, custodial wallet providers, and ICO portals. |
| Emergency Decree Amending the Revenue Code (No. 19) B.E. 2561 (2018) | 14 May 2018 | Adds cryptocurrency and digital token income to the catalogue of assessable income under Section 40(4)(h) and 40(4)(i) of the Revenue Code, and brings such income within the 15% withholding tax under Section 50. |
| Ministerial Regulation No. 380 (B.E. 2565) | 18 March 2022 | Permits residents who trade on SEC-licensed exchanges in Thailand to deduct capital losses on cryptocurrencies and digital tokens against capital gains within the same tax year. |
| Royal Decree No. 779 (B.E. 2566) | 16 August 2023 | Grants corporate income tax and VAT exemptions on the issuance and transfer of digital investment tokens, with effect from 14 May 2023. |
| Ministerial Regulation No. 399 (B.E. 2568) | 5 September 2025 | Exempts personal income tax on capital gains from cryptocurrency and digital token transfers conducted through SEC-licensed exchanges, brokers, or dealers in Thailand, for the period 1 January 2025 to 31 December 2029. |
The Revenue Code itself provides the umbrella authority. Section 40 lists every category of assessable income subject to personal income tax. Section 41 sets the source-of-income and remittance rules for residents. Section 42 lists exemptions and authorises the Ministry of Finance to issue Ministerial Regulations granting further exemptions, which is the legal basis for Ministerial Regulation No. 399. Section 50 imposes withholding obligations on persons who pay income covered by Section 40.
Definitions of Cryptocurrency and Digital Token
The Emergency Decree on Digital Asset Businesses B.E. 2561 supplies the operative definitions used throughout Thai tax law:
- Cryptocurrency is an electronic data unit created on an electronic system or network designed for use as a medium of exchange in the acquisition of goods, services, or other rights, or for the exchange between digital assets, and includes any other electronic data unit prescribed by the SEC.
- Digital token is an electronic data unit created on an electronic system or network for the purpose of either specifying the right of the holder to participate in an investment in a project or business (an investment token), or specifying the right to acquire goods, services, or other specific rights (a utility token).
The Revenue Department applies these definitions for tax purposes. Stablecoins, governance tokens, NFTs marketed as utility passes, and yield-bearing tokens generally fall within one of the two categories depending on their economic substance, not their marketing label.
Tax Residency in Thailand and Its Bearing on Cryptocurrency Income
Whether an individual must report cryptocurrency income in Thailand turns first on tax residency, then on the source of the income.
The 180-Day Rule under Section 41 of the Revenue Code
Section 41 paragraph 3 of the Revenue Code defines a tax resident of Thailand as any person who is present in Thailand for an aggregate of 180 days or more in any calendar year. The test is purely physical presence and applies regardless of nationality, visa class, or permanent residence status. Holders of long-term residency products such as the Long-Term Resident (LTR) Visa can become Thai tax residents in the same way as anyone else if they cross the 180-day threshold, although LTR holders enjoy specific tax benefits on certain categories of foreign-sourced income.
Thailand-Sourced versus Foreign-Sourced Digital Asset Income
For cryptocurrency, the source of the income is determined principally by where the disposal takes place and where the counterparty is situated. Trades executed on SEC-licensed exchanges in Thailand, or with brokers and dealers licensed by the Thai SEC, are generally Thailand-sourced. Trades executed on overseas exchanges or with overseas counterparties are foreign-sourced.
The distinction matters for two reasons. Thailand-sourced capital gains qualify for the Ministerial Regulation No. 399 exemption between 2025 and 2029. Foreign-sourced capital gains do not qualify for that exemption and remain subject to personal income tax when the income is remitted into Thailand under Section 41 paragraph 2 of the Revenue Code, regardless of when the original disposal occurred.
Categories of Taxable Cryptocurrency Income under Section 40 of the Revenue Code
The Emergency Decree Amending the Revenue Code (No. 19) B.E. 2561 inserted two new sub-categories into Section 40:
- Section 40(4)(h): any share of profits or any benefit derived from holding or possessing digital tokens.
- Section 40(4)(i): any benefit derived from the transfer of cryptocurrency or digital tokens, but only the amount in excess of the cost of investment.
These sub-paragraphs are the doctrinal basis on which every form of cryptocurrency income is taxed in Thailand. Different practical scenarios are mapped to one of the two limbs.
Capital Gains from Trading
Profits realised on the sale of cryptocurrency or digital tokens fall under Section 40(4)(i). Only the gain is taxable: the cost of acquisition is deducted from the disposal price. The Revenue Department permits two cost-basis methods: first-in-first-out (FIFO) and moving average cost. The chosen method must be applied consistently throughout the tax year and across the same type of digital asset.
Worked example. A resident purchases 1 BTC at 1,000,000 THB on 10 January and 1 BTC at 1,400,000 THB on 15 March. On 1 June he sells 1 BTC for 1,800,000 THB. Under FIFO the gain is 1,800,000 minus 1,000,000 equals 800,000 THB. Under moving average cost the average cost is 1,200,000 THB and the gain is 1,800,000 minus 1,200,000 equals 600,000 THB. Both gains are reportable under Section 40(4)(i) for the tax year of disposal.
Mining and Validator Rewards
Cryptocurrency received from mining is treated as assessable income at its market value on the date of receipt. The Revenue Department treats the mining receipt as the cost basis of the coin received: when the miner subsequently sells it, the capital gain or loss is calculated against that cost basis under Section 40(4)(i). Mining-related expenses, including electricity, hardware depreciation, and pool fees, are deductible against mining income provided they are documented and necessary for earning the income.
Staking Rewards, Airdrops, and Yield Farming
Tokens received from staking, airdrops, liquidity provision, and yield-bearing protocols are taxed under Section 40(4)(h) as a benefit derived from holding digital tokens. The taxable amount is the market value of the tokens on the date of receipt. The receipt then becomes the cost basis for any subsequent disposal. The Revenue Department's published practice does not currently exempt these returns under Ministerial Regulation No. 399, even when received through a Thai-licensed venue, because the exemption is drafted to cover capital gains on transfers, not periodic returns from holding.
Cryptocurrency Received as Salary or Payment
An employee paid in cryptocurrency receives Section 40(1) employment income, valued in Thai baht at the date of receipt. A self-employed professional paid in cryptocurrency receives income under the relevant Section 40 category for the underlying service, valued the same way. The crypto-payment character of the consideration does not change the doctrinal classification of the income.
Returns from Digital Investment Tokens
Profit shares and economic returns from digital investment tokens fall under Section 40(4)(h). For the issuer, the issuance and transfer of investment tokens may benefit from the Royal Decree No. 779 corporate income tax and VAT exemptions described below, but the holder's economic return remains assessable income for personal income tax purposes.
| Type of Crypto Income | Revenue Code Classification | Withholding Tax | Eligible for the 2025-2029 Exemption? |
|---|---|---|---|
| Trading gains on SEC-licensed Thai venue | Section 40(4)(i) | 15% (waived in practice for licensed-venue order-matched trades) | Yes |
| Trading gains on overseas exchange | Section 40(4)(i) on remittance | Foreign withholding may apply; Thai 15% generally not applied where the exchange is offshore | No |
| Mining or validator rewards | Section 40(4)(h) at receipt; 40(4)(i) on disposal | 15% on the receipt where payor is identifiable | Disposal only |
| Staking, airdrops, yield farming | Section 40(4)(h) | 15% where payor is identifiable | No |
| Crypto as salary | Section 40(1) | Progressive PAYE | No |
| Returns from digital investment tokens | Section 40(4)(h) | 15% | No |
The 15% Withholding Tax under Section 50 of the Revenue Code
Section 50(2)(f) of the Revenue Code requires the payor of income falling under Section 40(4)(h) or 40(4)(i) to withhold tax at 15% of the income paid. For non-residents, Section 50(2)(a) imposes a 15% withholding rate on Section 40(4) income paid to them. The withholding obligation rests on the payor; the payee receives a withholding certificate that can be set off against the final tax liability when the annual return is filed.
Implementing the withholding rule on a peer-to-peer or order-book exchange has always been technically problematic because the matched buyer and seller are anonymous to each other. The Revenue Department resolved this in practice in 2022 by accepting that withholding cannot reasonably be performed on order-matched trades on SEC-licensed exchanges, and licensed exchanges are not in practice required to withhold on each fill. Off-exchange transfers, custodial settlements where the counterparty is identifiable, payments by employers, and payments to advisors or service providers in cryptocurrency remain within the withholding regime in the ordinary way.
The Five-Year Personal Income Tax Exemption
The most significant recent development is Ministerial Regulation No. 399 (B.E. 2568), which the Ministry of Finance issued under the authority of Section 4 and Section 42(17) of the Revenue Code and which was published in the Royal Thai Government Gazette on 5 September 2025. The exemption window runs from 1 January 2025 to 31 December 2029.
Conditions of Ministerial Regulation No. 399
Ministerial Regulation No. 399 grants residents an exemption from personal income tax on the assessable income described in Section 40(4)(i), subject to four cumulative conditions:
- The income must arise from a transfer of cryptocurrency or digital tokens executed through a digital asset business operator licensed by the Thai SEC as an exchange, broker, or dealer.
- The transfer must occur during the window 1 January 2025 to 31 December 2029.
- The taxpayer must be a tax resident of Thailand for the relevant tax year.
- The income must be capital-gain income within the meaning of Section 40(4)(i), namely the amount realised in excess of the cost of investment.
The exemption applies automatically by force of the regulation. No advance ruling, application, or registration is required. The taxpayer should nevertheless retain trade confirmations, statements from the licensed venue, and acquisition records, because the Revenue Department remains entitled to audit returns retrospectively.
Capital Loss Deductions under Ministerial Regulation No. 380
Ministerial Regulation No. 380 (B.E. 2565), gazetted on 18 March 2022, allows residents trading on SEC-licensed venues in Thailand to deduct capital losses on cryptocurrency and digital token disposals against capital gains in the same tax year. The deduction is intra-year and intra-asset-class: losses cannot be carried forward to future tax years and cannot be set off against other categories of income such as employment or rental income. During the Ministerial Regulation No. 399 exemption window, the practical effect is limited because qualifying gains are exempt anyway, but the loss-offset rule remains relevant for non-qualifying transfers and for any transitional periods.
Activities Excluded from the Exemption
The following activities sit outside Ministerial Regulation No. 399 and remain fully taxable in the ordinary way:
- Transfers executed on overseas exchanges or with overseas brokers, including peer-to-peer transfers settled offshore.
- Mining receipts, staking rewards, airdrops, and yield-farming returns, which are categorised under Section 40(4)(h) rather than 40(4)(i).
- Cryptocurrency received as salary, professional fees, or commercial consideration.
- Business income earned by a juristic person or by an individual carrying on a digital asset trading business; the exemption is drafted for personal capital gains and not for trading-as-a-business activity.
- Returns from digital investment tokens and utility tokens classified under Section 40(4)(h).
VAT Treatment of Cryptocurrency and Digital Token Transfers
Cryptocurrency and digital token transfers are nominally services for VAT purposes. The Revenue Department has issued sequential exemptions to align the tax outcome with the underlying economic reality.
SEC-Licensed Exchange VAT Exemption
Transfers of cryptocurrency and digital tokens executed on SEC-licensed exchanges have been VAT-exempt continuously since 1 April 2022. The exemption was extended in 2024 and remains in force, removing the 7% VAT charge that would otherwise apply to the transfer itself. The exemption protects retail and professional traders from the cascading VAT cost that would otherwise make active trading uneconomic.
Royal Decree No. 779 and Digital Investment Tokens
Royal Decree No. 779 (B.E. 2566), in force from 16 August 2023, exempts companies and registered partnerships from corporate income tax and VAT on income from the issuance and primary-market sale of digital investment tokens, applied to all primary issuance from 14 May 2023. The same Decree exempts from VAT the secondary-market transfer of digital investment tokens by both individuals and juristic persons. Investment-token issuers benefit from the corporate income tax leg; individual holders benefit from the secondary-market VAT leg when they later transfer their tokens.
Foreign-Sourced Cryptocurrency Income and the Remittance Rule
Section 41 paragraph 2 of the Revenue Code applies to residents earning foreign-sourced income. As reinterpreted by the Revenue Department in Departmental Instruction Paw. 161/2566 (issued 15 September 2023, effective for income earned from 1 January 2024), foreign-sourced income is assessable for personal income tax in the year of remittance to Thailand, regardless of the year in which the income was originally earned. The previous practice, which exempted foreign-sourced income remitted in a year subsequent to the year of accrual, no longer applies for income earned from 1 January 2024 onward.
For cryptocurrency, this means that a Thai resident who realises a capital gain on an offshore exchange and later remits the proceeds into Thailand reports the gain as Section 40(4)(i) income for the year of remittance. The Ministerial Regulation No. 399 exemption does not assist because the gain is not realised through a Thai-licensed venue. Tax credit may be available against any foreign tax paid on the gain, in accordance with the relevant Double Tax Agreement between Thailand and the source country. Thailand maintains an extensive network of Double Tax Agreements with around 60 jurisdictions, and most include credit relief for taxes paid on capital gains.
Practical structuring options for Thai residents holding offshore positions therefore include realising the gain on a Thai-licensed venue (which currently qualifies for the exemption), keeping the proceeds offshore and not remitting them to Thailand in any year of Thai residency, or, where applicable, ceasing to be a Thai tax resident in the year of disposal. Each option carries collateral consequences and should be assessed in the context of the wider tax position and any applicable investment objectives in Thailand.
Filing, Recordkeeping, and Compliance Obligations
Annual Return on Form PND 90
Residents with cryptocurrency or digital token income file the annual personal income tax return on Form PND 90 (or PND 91 if the resident's only income is employment income, which would be the case where crypto was received as salary). The return is due by 31 March following the tax year, with an extension of approximately one week for taxpayers filing online via the Revenue Department's e-Filing system at efiling.rd.go.th.
Tax is computed at the progressive personal income tax rates, which range from 0% on the first 150,000 THB to 35% on income above 5,000,000 THB. Withholding tax already collected at source is credited against the final liability. Where Ministerial Regulation No. 399 applies, the relevant capital gains are simply not entered as taxable income on the return; supporting documentation should nonetheless be retained.
Recordkeeping Best Practice
Section 87 of the Revenue Code obliges taxpayers to keep records sufficient to substantiate every item on the return for at least five years. Practical recordkeeping for cryptocurrency activity includes:
- Trade-by-trade exports from each licensed exchange, broker, or dealer used during the year, in CSV or PDF format with timestamps in Thai time.
- Wallet addresses and on-chain transaction hashes for any transfers between exchanges or to private wallets.
- Acquisition records for tokens received from mining, staking, airdrops, or yield farming, with the THB market value applied at the date of receipt.
- Bank or e-money statements evidencing deposits and withdrawals between Thai accounts and exchange accounts.
- Documentation of any foreign tax paid on offshore disposals, for use in claiming Double Tax Agreement credit relief.
- Identification of the cost-basis method (FIFO or moving average cost) applied during the year, used consistently per asset.
Penalties for Non-Compliance
Section 27 of the Revenue Code imposes a surcharge of 1.5% per month, capped at the amount of the underpaid tax, on tax assessed and not paid by the due date. Section 22 of the Revenue Code adds penalties of up to 100% of the deficient tax for incorrect returns and 200% for failure to file. Criminal liability for tax evasion under Section 37 of the Revenue Code attracts a fine of up to 200,000 THB, imprisonment of up to seven years, or both, depending on the nature of the offence.

How Juslaws & Consult Can Help
Cryptocurrency taxation in Thailand has shifted from the punitive default of 2018 toward a calibrated regime that favours residents trading on Thai-licensed venues. The Ministerial Regulation No. 399 exemption is generous but precisely scoped, and the rules around foreign-sourced gains, mining, staking, and digital investment tokens all have their own contours. Our tax and digital asset practice advises Thai-resident traders, foreign investors, family offices, mining operators, and digital asset business operators on personal tax exposure, structuring, residency planning, and compliance reviews. We also support clients on the upstream regulatory questions, including SEC licensing for digital asset operators, broader cryptocurrency and digital token taxation for businesses, company registration for token-issuance vehicles, and contract drafting for crypto-denominated commercial relationships. If you are weighing whether to realise a position before the 31 December 2029 exemption sunset, structuring an offshore portfolio for remittance into Thailand, or filing your first PND 90 with crypto income, contact us for a confidential consultation.
Frequently Asked Questions
Is cryptocurrency legal in Thailand?
Yes. The Emergency Decree on Digital Asset Businesses B.E. 2561 (2018) makes the issuance, trading, and intermediation of cryptocurrencies and digital tokens lawful, subject to SEC licensing for businesses. Individuals may hold and trade digital assets without a personal licence; only the operators that intermediate the transactions need a licence.
Are my crypto profits really tax-free in Thailand?
Capital gains on cryptocurrency and digital token transfers executed through SEC-licensed exchanges, brokers, or dealers in Thailand are exempt from personal income tax for transfers occurring between 1 January 2025 and 31 December 2029, under Ministerial Regulation No. 399 (B.E. 2568). Gains realised on overseas exchanges, plus mining, staking, airdrop, salary, and profit-share income, are not exempt and remain taxable under the ordinary rules.
Who is a tax resident of Thailand?
Section 41 of the Revenue Code defines a tax resident as a person physically present in Thailand for an aggregate of 180 days or more in any calendar year. Nationality, visa class, and permanent residence status are irrelevant. Days are counted as physical days of presence, regardless of the time of arrival or departure.
Do I have to pay Thai tax on crypto gains made on Binance or Coinbase?
Gains made on overseas exchanges are foreign-sourced. They are not covered by the Ministerial Regulation No. 399 exemption. They become taxable in Thailand for a Thai resident in the year the proceeds are remitted into Thailand, under Section 41 paragraph 2 of the Revenue Code as reinterpreted by Departmental Instruction Paw. 161/2566 (effective for income earned from 1 January 2024). Foreign tax credit may be available under an applicable Double Tax Agreement.
What is the withholding tax rate on crypto income in Thailand?
Section 50(2)(f) of the Revenue Code requires the payor of income falling under Section 40(4)(h) or 40(4)(i) to withhold tax at 15%. The Revenue Department accepts that withholding cannot be performed on anonymous order-matched trades on SEC-licensed exchanges, so these are not subject to withholding in practice. Off-exchange transfers, employer payments, mining payouts, and staking rewards remain within the withholding regime when the payor is identifiable.
Can I deduct crypto trading losses against my employment income?
No. Ministerial Regulation No. 380 (B.E. 2565) allows losses on cryptocurrency and digital token disposals to be netted against gains in the same category and the same tax year on SEC-licensed venues, but losses cannot be carried forward and cannot be set off against employment income, rental income, or other categories of assessable income.
How are mining rewards taxed?
Mining rewards are assessable income under Section 40(4)(h) at the THB market value on the date of receipt. The receipt becomes the cost basis for any subsequent disposal, which is then a Section 40(4)(i) event. Documented mining expenses, including electricity, hardware, and pool fees, are deductible against mining income. The Ministerial Regulation No. 399 exemption does not apply to mining income because it is structured as a return on holding rather than a transfer.
How are staking and airdrops taxed?
Staking rewards, airdrops, and yield-farming returns are taxed under Section 40(4)(h) at the THB market value on the date of receipt. The 15% withholding tax under Section 50(2)(f) applies where the payor is identifiable. The exemption under Ministerial Regulation No. 399 does not extend to these returns because the regulation covers transfer income only.
Is VAT charged on cryptocurrency trading in Thailand?
Cryptocurrency and digital token transfers conducted on SEC-licensed exchanges have been VAT-exempt since 1 April 2022, with the exemption renewed and extended. The 7% VAT does not apply to qualifying trades. Royal Decree No. 779 (B.E. 2566) further exempts the issuance and secondary-market transfer of digital investment tokens from VAT.
Which form do I use to report crypto income?
Personal income tax is filed on Form PND 90 for residents with mixed sources of income, including any Section 40(4)(h) or 40(4)(i) crypto income. Form PND 91 is used only where the resident's sole income is employment income. The deadline is 31 March of the year following the tax year, with a short extension for online filings via efiling.rd.go.th.
What records must I keep for the Revenue Department?
Section 87 of the Revenue Code requires taxpayers to retain records sufficient to substantiate every item on the return for at least five years. For cryptocurrency, this means trade exports from each licensed venue, on-chain transaction hashes, mining and staking receipts with THB valuations, deposit and withdrawal statements, and documentation of any foreign tax paid on offshore disposals.
What happens if I do not declare crypto income?
The Revenue Department may assess the unpaid tax with a surcharge of 1.5% per month under Section 27, capped at the amount of the underpaid tax, plus a penalty of up to 200% of the deficient tax under Section 22 for failure to file. Criminal sanctions under Section 37 include a fine of up to 200,000 THB and imprisonment of up to seven years for tax evasion.
Will the exemption be renewed after 31 December 2029?
Ministerial Regulation No. 399 has a fixed sunset date of 31 December 2029. Renewal would require a further Ministerial Regulation. The wider policy of positioning Thailand as a digital asset hub suggests continued favourable treatment is plausible, but no extension is automatic and prudent planning should not assume one.
Can a foreign investor benefit from the Ministerial Regulation No. 399 exemption?
The exemption applies to tax residents of Thailand. A foreign investor who is in Thailand for 180 days or more in a calendar year is a Thai tax resident and qualifies on the same terms as a Thai national. Trading must still be executed through an SEC-licensed Thai exchange, broker, or dealer for the exemption to apply. Foreign investors weighing residency strategy may also wish to consider the Long-Term Resident (LTR) Visa and the broader landscape of investment opportunities in Thailand.
