Por.161/2566 offshore income tax remittance rule impact
Effective 1 Jan 2024
Revenue Department Order Por.161/2566 (issued September 2023, effective from the 2024 tax year) reverses Thailand's prior carve-out that exempted offshore income from personal income tax unless remitted into Thailand in the same year it was earned. Under the new rule, any offshore income brought into Thailand in any subsequent year is taxable. The change has materially reshaped HNW client booking behaviour, accelerating onshore consolidation for income-generating portfolios while pushing growth assets toward Singapore booking centres. Thai private banks have built tax-planning advisory bench strength as a result.

What not to do with it
Por.161 is a regulatory regime change rather than a numeric statistic; included here because of its material impact on onshore AUM consolidation and offshore booking-centre flows.
