Company Compliance in Thailand

A compliance calendar should reflect the business that exists: entity type, accounting period, ownership, activities, sites, staff, tax status and any special approvals. A generic calendar can miss an event-driven requirement or apply a deadline meant for another entity.

Create an obligations register with the responsible authority, legal or approval basis, due-date rule, owner, preparer, reviewer and evidence of completion. Separate statutory duties from contractual obligations such as insurance, lender reporting and lease conditions. Both can matter, but they have different consequences and sources.

Close and reconcile the books regularly, review payroll and payments, and identify the returns actually required. VAT registrants generally file PP.30 monthly, including months without sales. Withholding, payroll and other returns depend on the facts and registrations.

Use the Revenue Department’s current calendar for the exact form, period, filing method and payment deadline. Standard paper due dates, electronic extensions, weekends and special notices can differ. Keep filing and payment as separate completion checks, with the official acknowledgement and receipt for each.

Have a second person review unusual transactions, nil returns and large changes. A zero-sales month does not necessarily remove returns or record obligations, and an accountant’s invoice does not prove that a return was accepted.

For an ordinary Thai private limited company, arrange the annual statements and audit early enough for shareholder approval within four months of the accounting-period end. DBD financial-statement submission is due within one month of approval. Different entity types have different rules; confirm the category before using this timetable.

The private company’s annual shareholder-list copy, Bor.Or.Jor.5, is a distinct filing generally due within 14 days of the ordinary general meeting. Keep it consistent with the company’s actual shareholder register and the relevant meeting date. Filing a list does not itself create or transfer share ownership.

Schedule notices, approvals, signatures and filing access before the deadlines. Keep the final signed statements, auditor’s report, meeting records, shareholder information and accepted submission. Do not leave everything to the last DBD filing date.

The ordinary corporate income-tax timetable includes an annual return within 150 days of the accounting-period end and, where applicable, a half-year return within two months after the first six months of the period. Confirm the entity’s obligations, estimates and any current electronic filing extension.

Reconcile the tax calculation to the accounts, withholding credits, payments and supporting schedules. DBD acceptance of financial statements does not show that the Revenue Department return and payment are complete. Keep each process visible in the calendar.

The official employer-registration procedure describes registration of the employer and insured employees within 30 days from having the first employee, subject to the applicable coverage rules. Confirm employee eligibility and the appropriate Social Security Office process rather than relying on an old brochure’s wording.

Maintain payroll, contribution, leave, working-time and safety records as required. Track hires, pay changes, departures and any work-rule obligations. For foreign staff, keep visa, stay, work-authorisation, reporting and employer-change tasks separate, with a responsible person for each.

An issued licence, certificate or promotion approval can carry scope, location, capital, reporting and operating conditions. Record those conditions alongside the expiry or review dates. Some obligations arise even when the permission has no simple annual renewal.

Before adding an activity, site, product, shareholder or manager, check whether the existing permission must be amended or a notification made. Make the approval check part of the change process rather than waiting for the next annual review.

Maintain the entity’s registers, authorisations, resolutions and registered particulars. Review changes to directors, signing powers, address, capital and ownership with the relevant adviser and authority. An internal decision and completion of the required registration or notification are separate steps.

Keep company-controlled access to filing systems and a reliable handover when staff or providers change. Use authorised delegation and approval controls. Store evidence in a structure that another responsible person can navigate without relying on one individual’s email account.

Review privacy notices, access, processors, retention and incident response against the personal data actually handled. Match the retention schedule to record type and legal basis. Do not destroy records simply because a software subscription ends or a routine retention date passes during a dispute.

Track contract notice dates, insurance, intellectual-property renewals and customer commitments. Preserve original evidence and readable exports. A central calendar should point to the responsible records without unnecessarily copying passports, payroll or other sensitive data into a broadly shared task list.

Identify the precise missed duty, period, authority and current status. Obtain the actual filing history and payment evidence before assuming a provider completed it. Ask the authority or qualified adviser about correction, penalties, interest and any effect on other permissions.

Do not backdate meetings, fabricate receipts or submit inconsistent documents to make the calendar look complete. Record the corrective action, owner and accepted outcome, then address the process that allowed the omission. Negotiating with a provider does not itself extend a statutory deadline.
