Mileage rates in Thailand
Thailand has no private-sector tax-free mileage rate. The 4 baht a kilometre is what the government reimburses its own officials for using a private car on official travel, set by the Ministry of Finance in July 2007 and unchanged since; a motorcycle is 2 baht. Private employers set their own rate, and the Revenue Department treats a payment as tax-free only where it is a necessary expense of assigned work, approved and evidenced.
