How can expats obtain a Thai Tax Identification Number (TIN) and what is the process involved?

The process of obtaining a Thai Tax Identification Number (TIN) for expats generally requires a visit to the local Revenue office, where applicants need to provide their passport and proof of address. Some users have reported completing the process in about 10 minutes with no fees involved. However, there are discussions about tax obligations related to the DTV (Digital Nomad Visa) holders, emphasizing that becoming a tax resident after 180 days does not necessarily mean one must file taxes unless they have assessable income. It's also noted that DTV holders may not have to file tax returns.
