Do You Know How to Register a Tax ID Number in Thailand?
With recent changes in Thailand’s tax regulations, it’s important for individuals to familiarize themselves with the new rules, especially concerning the declaration of income earned abroad. One key element of ensuring compliance is to register a Tax ID number in Thailand. This step is obligatory for all taxpayers in Thailand and must be completed before submitting tax returns by March 31st, 2025. If you already do your taxes or have a work permit, you already possess a Tax ID Number. But the pink ID card is not linked to your tax number. Thai citizens use their Thai ID number for taxes but expats living in Thailand normally do not have one.
This is an example of a Tax ID number in Thailand for a foreigner done in Bangkok on 15th November 2024.

Understanding Tax Residency in Thailand
If you’ve stayed in Thailand for more than 180 days in a calendar year, you’re considered a tax resident as defined by Thai law. As a tax resident, you’re required to follow Thailand’s tax laws, including the new rules about foreign income. We have prepared a detailed document explaining these new regulations, but it might be a bit complex. If this affects you, you may need to register a Tax ID number in Thailand.
New Rules on Foreign Income Starting January 1st, 2024
Starting January 1st, 2024, tax residents must declare any income earned abroad if it is brought into Thailand, regardless of when it was earned. This is a significant change from the previous rule where only income made in Thailand was taxed if remitted in the same tax year. Obtaining a Tax ID Number is essential to comply with these new regulations.
