The effective tax rate is the actual percentage of income paid in tax — lower than the top marginal rate because lower brackets are taxed at lower rates.

Thailand uses a progressive income tax system with rates ranging from 5.00% at the lowest bracket to 35.00% at the top bracket (2024).

The number and thresholds of brackets vary by country and are typically adjusted annually for inflation.

Tax residents are liable for income tax at the same rates as citizens — 5.00% to 35.00% — on their Thailand-sourced or worldwide income depending on the tax regime.

Freelancers and self-employed individuals in Thailand typically pay income tax at the same progressive rates as employees — 5.00% to 35.00% — on their net profit after allowable business expenses. Unlike employees who split social security with their employer, self-employed workers often pay both the employee (5.00%) and employer (5.00%) portions themselves, significantly increasing the total tax burden. Self-employed workers are usually required to file a self-assessment tax return and make advance tax payments during the year.
