Foreign-Sourced Income

If you transfer your investments to Thailand, you may be subject to capital gains tax. Any tax already paid can potentially be used as a credit against the tax owed in Thailand. Remitting funds to Thailand from investments would classify as an assessable income source.

The Canadian / Thai DTA is quite favourable for Thai tax residents. Pensions are only taxable in Canada and for investment capital gains you can use any tax paid in Canada as a credit.

For Thai tax residents, capital gains are calculated based on the gains realised when selling assets. This applies regardless of whether the investments were held before 2024. It does not follow the “cash in the bank” rule.

Investments are taxed on all-time capital gains. Unlike pre-2024 cash in the bank, investment gains are taxable regardless of when the assets were acquired.

Yes, crypto and investment income can be taxed for DTV visa holders if they are tax residents.  Residents pay tax on Thai-sourced income and foreign income brought into Thailand, which includes capital gains or dividends derived from cryptocurrency. Mining income is also taxable.

It is not the whole account profit that is taxed, but the gains on assets you sell and remit into Thailand. For example, if you sell shares for a gain and remit the proceeds, the gain portion is taxable in Thailand. Accurate records of cumulative gains are essential for compliance.
