Very few I suspect including sections of the revenue department.I went to Jomtien tax office this morning after following the simple tax guide to get a tin number as per the law and came away empty handed.They told my wife and I to come back next year with a bank statement.This will be way past the mandated 60 days deadline for bringing assessable income into Thailand and my residence cert. might be expired after 30 days.A total waste of time and money!
