Short Answer
Do not put one date into the checklist and label it simply “dissolution date.”
Different Thai corporate and tax obligations can run from different events.
For a voluntary dissolution by shareholders, the company is legally dissolved when the special resolution to dissolve is passed. The liquidator’s corporate steps—such as registering the dissolution and notifying creditors—are tied to that legal dissolution date.
Corporate income tax uses a different trigger: section 72 of the Revenue Code treats the date on which the registrar registers the dissolution as the last day of the accounting period and starts related tax deadlines from that registration event.
Value added tax can use yet another concept: cessation of the taxable business.
Why This Matters
A dissolution checklist can look perfectly organised and still be wrong if the trigger date is wrong.
The real implementation problem is that a team may count the correct number of days from the wrong starting point. A company can therefore miss a filing or tax deadline even though its spreadsheet appears precise.
Typical Scenario
Shareholders pass a special resolution to dissolve a Thai company.
The dissolution is registered with the DBD several days later.
The finance team then prepares one timetable for DBD registration, creditor notice, liquidation accounts, corporate income tax, value added tax and final liquidation.
Management asks:
“Which date should we use as Day 1?”
There is no single answer for every task.
Practical Analysis
01Start with the legal dissolution event.
DBD guidance and its published interpretation of section 1236 confirm that where shareholders voluntarily dissolve a company by special resolution, the dissolution is legally effective from the date of that resolution.
That is important because the company does not wait for the registrar to create the dissolution.
02Corporate liquidation steps use the company-law trigger.
DBD currently instructs liquidators to file the dissolution registration within 14 days from the company’s dissolution.
Its liquidation guidance also requires publication of the dissolution notice and registered-mail notice to creditors within the same 14-day period.
For a voluntary shareholder dissolution, the timetable should therefore start from the date the special resolution takes effect, subject to the actual terms of the resolution and the reason for dissolution.
03Corporate income tax uses the registration date.
Revenue Code section 72 expressly provides a different rule.
The liquidator and manager must notify the Revenue Department within 15 days from the date the registrar accepts registration of the dissolution. For income-tax purposes, that registration date is treated as the final day of the accounting period, and the company’s return and tax obligations follow from that tax accounting period.
This is why the corporate and tax calendars should not be merged into one undefined “dissolution date.”
04Value added tax needs its own cessation analysis.
Section 85/15 of the Revenue Code requires a VAT-registered operator to notify cessation of business within 15 days from the date it ceases the VAT business.
That factual cessation date may need to be reconciled with the corporate dissolution and registration dates.
05Liquidation creates later triggers as well.
If liquidation continues, periodic liquidation reporting and annual shareholder reporting may arise. Once the final liquidation report is approved, a separate deadline applies to registration of completion of liquidation.
The project therefore has multiple clocks, not one.
What We Usually Look At
We map the shareholder resolution date, effective wording of the resolution, DBD registration date, actual business-cessation date, VAT status, accounting cut-off, creditor notices, liquidation financial statements, tax returns and final liquidation approval.
Common Traps
Typical mistakes are using the DBD registration date for every corporate deadline, using the shareholder-resolution date for every tax deadline, treating cessation of business and dissolution as automatically identical, and failing to record the trigger beside each task.
Practical Next Step
Use a trigger matrix:
obligation → legal trigger → deadline → evidence of trigger → responsible person
Avoid a spreadsheet column headed only “dissolution date.”
