On 23 December 2021, the Thai Revenue Department has published a notification on amendments to the filing deadlines for Country-by-Country (CbC) reports. Previously CbC report filing deadline was as same as the annual tax return deadline, which is generally due 150 days following the close of the accounting period.

According to this notification, the CbC reporting deadline has been amended to 12 months after the close of the relevant accounting period. The notification also indicates that in cases where secondary local filing requirements apply for non-parent constituent entities resident in Thailand, the deadline to submit a CbC report is 60 days after the receipt of a notice to file from the tax authority.

Furthermore, Thailand’s CbC reporting requirements apply from 1 January 2021, therefore the first primary CbC report filing will be due by 31 December 2022.
