Do I need a Thai tax number if I don't have tax liability in Thailand?

Hi,

I have a tax residency question.

As far as I understand, I don’t currently have any tax due in Thailand. The money I’m spending here is not from income earned this year, and I’m leaving Thailand in August. Until then, I can live from previous finances.

For administrative purposes, I wanted to file a tax return in Thailand and obtain a Thai tax number. However, when I went to apply for one, I ended up in a frustrating situation. The officer wanted me to sign documents immediately. I explained that I don’t speak Thai and simply wanted to translate the documents first before signing them. She became quite pushy, and I felt uncomfortable signing something I couldn’t read. Eventually, she found a small issue in the application and refused to issue the tax number.

This made me wonder whether I actually need a Thai tax number at all if I don’t have any tax liability in Thailand.

Am I understanding this correctly, or am I missing something? Does anyone have experience with this?

Thanks in advance!

Highly unlikely you're a Thai tax resident if you're here on a tourist visa (DTV)

What can we glean from this post? Yet another worry for DTV holders. 'Power battles' in the income tax office with the result of not knowing whether you wind up on the right or wrong side of the law.

Missing the point that you are in Thailand at the Thai revenue office.

The national language is Thai.

If you have a cell phone, download google translate, make a picture of the document and translate that using the app.
