Thailand BOI guide

BOI tax incentives

Tax privileges are activity-based, time-limited and often capped by reference to invested capital.

Corporate income tax

The best known privilege is a corporate income tax exemption for a defined number of years, with the length driven by the activity group and any additional merit-based criteria met by the project. Exemptions are commonly capped by reference to the investment amount excluding land and working capital.

Duties and other privileges

Depending on activity, promotion may include import duty exemption or reduction on machinery and on raw materials used for export production, plus permission for additional deductions in some merit categories.

What tax privileges do not do

They do not remove VAT obligations, withholding tax, payroll obligations or accounting and audit duties. Promoted companies also carry reporting conditions and can lose privileges if conditions are breached.

BOI eligibility depends on the specific activity, project and current regulations. This page provides general information and is not official BOI advice.
