The Thai personal income tax filing season for the 2025 tax year has already begun. As in the previous year, the approaches adopted by the Thai tax authorities—particularly those affecting foreign-sourced income—continue to raise concerns among many taxpayers, especially foreigners.

One of the most significant developments remains the approach adopted by the Thai tax authorities in relation to foreign-sourced income remitted into Thailand. This approach, which was first applied in 2024, continues to be applied in 2025 and has resulted in ongoing uncertainty and confusion among taxpayers.
