Sorry this is probably a really dumb question as a first post but I wanted to make sure, is the Taiwan Taxpayer Identification Number (TIN) in Taiwan just our ARC number? I don’t see any mention of it in the tax forms, and maybe because I’m extremely tired right now, the documentation from the MOF website is confusing me.
