Short Answer
No—not merely because the auditor is late.
An audit delay does not automatically move statutory corporate or tax deadlines.
For a Thai limited company, annual compliance contains several separate clocks. The annual financial statements must go through the corporate approval and Department of Business Development filing process. The annual corporate income tax return generally has its own 150-day deadline from the end of the accounting period, and the Revenue Code requires the relevant audited accounts to accompany that filing.
If the audit is at risk of missing a deadline, the company should identify the affected obligation and any legally available extension rather than treating the auditor’s revised delivery date as an extension granted by the authority.
Why This Matters
Management often receives one status report:
“Accounts are still with the auditor.”
That description can hide several different exposures.
The annual shareholders’ meeting may be overdue. The shareholder list may still be capable of being filed. The corporate income tax return may have a different deadline. A half-year tax filing may already have fallen due independently of the annual audit.
The source matter involved multiple entities with audit, corporate-registration and tax backlogs. The practical insight was to track each obligation by entity and accounting period rather than give the whole group one “audit pending” status. fileciteturn13file1L42-L46
Typical Scenario
A Thai company reaches year-end with unresolved accounting reconciliations.
The auditor says the signed financial statements will be delivered later than originally planned.
Finance asks:
“Can we just move the tax and DBD filings to the new audit date?”
Not unless the relevant law or authority has actually moved those deadlines.
Practical Analysis
01Separate the annual shareholders’ meeting from the audit project plan.
Department of Business Development guidance states that a Thai limited company should present its financial statements to the annual general meeting within four months after the end of the accounting year.
The audit timetable should therefore be built backward from the corporate deadline.
02Track the financial-statement filing separately.
For a limited company, DBD guidance requires the approved financial statements to be filed within one month after approval by the shareholders’ meeting.
The filing clock is therefore connected to the meeting—not simply to the date the auditor originally promised the report.
03Do not forget the shareholder list.
The company’s annual shareholder list, commonly known as Bor.Or.Jor.5, is generally filed with DBD within 14 days after the annual general meeting.
That is another separate compliance item.
04Corporate income tax has its own statutory deadline.
Revenue Code section 68 requires the annual corporate income tax return and tax payment within 150 days after the end of the accounting period.
Section 69 requires the relevant accounts audited and certified by the prescribed auditor to accompany the filing.
Auditor delay therefore creates a compliance problem; it does not itself create extra time.
05Half-year tax should remain on a separate line.
Section 67 bis establishes the half-year corporate income tax framework, generally requiring filing and payment within two months after the first six months of the accounting period for taxpayers within its scope.
Annual audit delay is not the trigger for that obligation.
06Verify any extension before using it.
Electronic-filing extensions, holiday adjustments or exceptional relief can change the practical deadline.
Use the actual applicable Revenue Department or DBD instrument for the entity and year concerned. An internal email saying “the auditor needs two more weeks” is not evidence of official relief.
What We Usually Look At
We prepare an entity-by-entity schedule covering accounting year-end, audit status, annual general meeting, financial-statement filing, shareholder-list filing, half-year tax, annual tax, any outstanding returns, authority notices and evidence of any extension.
Common Traps
Typical mistakes are using one “audit due date” for every obligation, assuming tax can wait until the audit is convenient, overlooking Bor.Or.Jor.5, applying an extension from the wrong year and reporting the whole group as overdue when some entities or filings remain current.
Practical Next Step
Create an obligation matrix:
entity → obligation → legal trigger → ordinary deadline → audit dependency → available extension? → owner → evidence of completion
Where the audit threatens a statutory date, escalate that specific deadline immediately rather than moving the entire compliance calendar.
