How capital gains tax works in Thailand
Thailand does not have a standalone personal capital gains tax. In most cases, gains are taxed under the ordinary personal income tax rules, so the effective rate can be as high as 35% depending on the taxpayer's total income.
Important exemptions include gains on listed shares sold on the Stock Exchange of Thailand, gains on mutual fund units, gains on certain non-interest-bearing debt instruments, and qualifying digital-asset gains through licensed Thai platforms from 1 January 2025 to 31 December 2029.
Thai residents also need to track foreign-source gains carefully, because gains and other investment income earned from 1 January 2024 onward can become taxable when remitted to Thailand.

Watch out for
- Thailand taxes many gains as ordinary income, so the label "capital gains" can be misleading if the asset is not one of the statutory exemptions.
- Digital asset gains are only exempt through licensed Thai exchanges, brokers and dealers during the 2025 to 2029 window.
- Capital losses generally do not offset capital gains under the same broad way investors expect in a dedicated CGT system.
