Latest tax return and transfer pricing filing deadlines

HLB Thailand Tax Team


As we head into the last months of the tax filing season, here is a recap of the latest filing dates for annual tax returns and transfer pricing disclosure forms plus the extensions granted for filing other tax returns.

E-filing of 2020 personal income tax returns

The deadline for filing personal income tax returns (PND 90 and PND91) electronically for the 2020 tax year has been extended to 30 June 2021.

E-filing of corporate income tax returns and transfer pricing disclosure forms

The deadline for filing corporate income tax returns online that are due for filing in May and June 2021 has been extended to 30 June 2021. For companies listed in the SET, the extension will only be granted if the company had scheduled its AGM between 26 April and 30 April and the meeting has been postponed by not more than one month, due to COVID-19 control measures.

Limited companies with a 31 December 2020 year end will therefore now have until Wednesday 30 June 2021 to file their annual corporate income tax return electronically.

Limited companies that must submit a transfer pricing disclosure form will also have until Wednesday 30 June 2021 to file the form electronically.

Only companies with Baht 200 million (USD 6.7M) or more in revenues in an accounting period must file the disclosure form with the Revenue Department, disclosing details of their related parties and transactions during the year with related parties.

The Director-General of the Revenue Department has issued a notification making it mandatory for companies to submit their transfer pricing disclosure forms online unless they have reasonable grounds for filing a paper form.

Companies listed in the SET that are eligible for the filing date extension must notify the dates of the first AGM and the rescheduled AGM to the Director-General of the Revenue Department on the Revenue Department’s website by 31 May 2021.

Extended deadline for e-filing of WHT and VAT returns

For monthly WHT returns and VAT returns filed electronically, which are normally due for filing during the months of February 2021 to June 2021, the filing date has been extended to the last day of the month.

This extension therefore applies to withholding tax returns (PND 1, PND 2, PND 3, PND53) and VAT returns (Por Por 30 and Por Por 36) for the tax months of January 2021 to May 2021.
