Thailand Crypto Tax Guide 2026

Thailand taxes cryptocurrency under Section 40(4)(h) of the Revenue Code, which classifies crypto gains as assessable income from "capital gains on transfer of digital assets." The Revenue Department has issued guidelines clarifying that both capital gains from selling crypto and income from mining/staking are taxable. Thailand applies a 15% withholding tax on crypto gains paid through authorized exchanges, which serves as a prepayment of your annual personal income tax (PIT) liability. The Securities and Exchange Commission (SEC) regulates crypto exchanges in Thailand, and authorized exchanges report transaction data to the Revenue Department.

Crypto gains are included in your total assessable income and taxed at progressive PIT rates: 0% up to THB 150,000, 5% for THB 150,001-300,000, 10% for THB 300,001-500,000, 15% for THB 500,001-750,000, 20% for THB 750,001-1,000,000, 25% for THB 1,000,001-2,000,000, 30% for THB 2,000,001-5,000,000, and 35% above THB 5,000,000. The 15% withholding tax by authorized exchanges is credited against your annual PIT liability. If your effective PIT rate is below 15%, you can claim a refund of the excess withholding. Capital gains are calculated as disposal proceeds minus acquisition cost.

Authorized Thai exchanges withhold 15% tax on gains at the time of disposal. For 2024 onwards, the government has explored exemptions for certain types of crypto income, including potential VAT exemptions on crypto transfers through authorized exchanges. Losses from crypto disposals can offset crypto gains within the same tax year when calculating annual PIT, but losses cannot be carried forward. Gains from crypto-to-crypto trades on authorized exchanges are subject to the same withholding and reporting rules. Transactions on foreign exchanges are self-reported without withholding.

Mining and staking rewards are treated as assessable income under Section 40(8) — income from business or other sources. They are valued at THB fair market value when received and taxed at your marginal PIT rate. If mining constitutes a business, additional requirements may apply. Airdrops are taxable at receipt at their fair market value. DeFi yields and lending interest are treated similarly as assessable income.

Taxxy calculates crypto gains using FIFO and converts all values to THB using historical exchange rates. The platform tracks the 15% withholding tax deducted by exchanges and calculates the remaining PIT liability or refund due. Taxxy generates an annual income summary compatible with Revenue Department filing requirements and separates capital gains from income events like staking and mining.
