February Focus: Tax Season is Coming

February marks the beginning of tax season in Thailand. With the March 31 personal income tax deadline approaching, now is the time to get organized.

 

Why February Matters

The March 31 deadline applies to personal income tax (PIT) for the previous calendar year (2025). If you:

• Worked in Thailand during 2025
• Received salary from a Thai company
• Are a business owner taking income
• Spent 180+ days in Thailand

...you likely need to file.

• Covers: January 1 - December 31, 2025
• Deadline: March 31, 2026 (can extend to May 31 online)
