On 14 January 2021, the Revenue Department of Thailand has published a notice making it mandatory for companies to submit their transfer pricing (TP) disclosure forms via the Revenue Department’s website or the Ministry of Finance’s electronic tax service unless they have reasonable grounds for filing a paper form, effective for accounting periods commencing on or after 1 January 2020.
Only companies with Baht 200 million or more in revenues in an accounting period must file the TP disclosure form. If a TP disclosure form is filed by paper it must be accompanied by a letter explaining the causes why the company cannot submit the form through online platform.
