Submitting financial statements to Thailand's DBD: deadlines and penalties
DBD deadlines for Thai companies and partnerships, the e-Filing process, what to prepare, how to request an extension, and the fine ceiling.
A limited company must submit financial statements through DBD e-Filing within 1 month of the date a meeting approves them. A registered partnership must submit within 5 months of the closing date. Missing the deadline carries a civil fine, so book your auditor and meeting date early.
Who has to submit statements?
Juristic persons with a duty to keep accounts, such as limited companies and registered partnerships, submit statements to the Department of Business Development. This is separate from filing PND 50 with the Revenue Department.
How do companies and partnerships differ?
- Limited company: put audited statements to a shareholders' meeting for approval within 4 months of the closing date, then submit within 1 month of approval
- Registered partnership: submit statements and the audit report within 5 months of the closing date
Under the DBD manual, a registered partnership with capital up to 5 million baht, total assets up to 30 million baht, and total revenue up to 30 million baht does not need a certified public accountant to audit its statements. Its PND 50 filing still needs a report from a tax account auditor.
What are the DBD e-Filing steps?
- Close the accounts and finish the financial statements
- Have them audited as the law requires
- For a company, hold a shareholders' meeting to approve them
- Prepare the data and files in the DBD e-Filing format
- Submit through the system and keep the filing evidence
The steps before this are in closing your books.
What should you prepare before logging in?
- The audited financial statements
- The auditor's report, as applicable to your business
- The approval meeting date, for a company
- Entity details and system access rights
Do not wait until the last day, because you may need time to fix files or request information from the auditor. If you change who handles your accounts, also check who holds system access.
What does late or missed submission cost?
The Department of Business Development's manual treats failure to submit on time as a civil-penalty offense, with a ceiling of up to 50,000 baht each for the entity and for the managing director or managing partner.
That figure is a ceiling, and not every case pays the full amount. The actual amount depends on the agency's decision.
Can you request an extension?
With a necessary reason, you can write to the Director-General of the Department of Business Development to request an extension or postponement. It must be filed before the deadline and is decided case by case.
Do not assume that filing a request means you have an extension. Keep the reply and plan to submit as soon as possible.
Can you handle it yourself?
Yes, if your audited statements are finished, your data is complete and someone manages the system. Most problems come from starting late, such as a year's worth of incomplete documents or not booking an auditor in time. Having our bookkeeping team involved during the year helps reduce this risk. See the service scope on the pricing page.
Frequently asked questions
How do you count if you do not close on December 31?
Count from your actual closing date, which is not always December 31.
Does filing PND 50 count as DBD submission?
No. They are separate duties and systems, so check both.
Does a company with no income still submit?
Assume the duty remains for as long as the juristic person has not been dissolved through the proper process. If unsure, ask an accountant or the Department of Business Development.
