A resident is taxed on income from Thai sources and, under the Por.161/2566 interpretation effective 1 January 2024, on foreign-source income remitted into Thailand in any year (the previous 'same-year-only' interpretation no longer applies).

The Revenue Code is the primary tax statute of Thailand. It governs personal income tax (PIT), corporate income tax (CIT), value added tax (VAT), specific business tax (SBT) and stamp duty. The Code is administered by the Revenue Department of the Ministry of Finance and is regularly supplemented by Revenue Department Notifications (Por.), Departmental Instructions, and Royal Decrees that grant exemptions or set detailed thresholds.
