Thai social security contributions fund healthcare, unemployment, and pensions:
Contributions cover healthcare at government hospitals, maternity benefits, disability, death benefits, and unemployment insurance.
Thailand's consumption tax system:
VAT registration required for businesses with annual revenue exceeding ฿1.8 million. Certain goods and services are exempt or zero-rated, including basic food, agricultural products, and exported services.
Important deadlines for Thai taxpayers:
Individual tax returns for 2024 must be filed by March 31, 2025. Monthly VAT returns are due by the 15th of the following month.
Popular tax deductions for Thai taxpayers:
