DBD e-Filing | Department of Business Development | Submission of annual financial statements and shareholders’ meeting documents |
II. RD e-Filing (Revenue Department Electronic Filing System)

IV. TMA Group Professional Reminder
RD e-Filing is responsible for tax filing, while DBD e-Filing handles statutory corporate document submissions—both are indispensable.
There are mandatory monthly and annual filing obligations that must be fulfilled according to the regulations set by the Thai Revenue Department and the Department of Business Development (DBD).
Failure to submit on time or omission of submissions will result in substantial penalties and potential tax audit risks.
