Common ongoing company obligations

This is a non-exhaustive routing checklist, not a compliance calendar or certification. Obligations depend on entity, accounting period, activity, licences, promotion, employees, transactions and regulator.

Confirm separately: DBD corporate changes, shareholder and financial-statement filings; accounting records and auditor requirements; Revenue Department CIT, VAT, withholding and transfer-pricing filings; SSO and payroll; DOE work permissions and notifications; BOI certificate conditions; sector licences and data and privacy duties.

Do not assume a Thai limited company is audit-exempt because it falls below a generic asset or revenue threshold. Have a Thai accountant or auditor confirm the entity's financial-statement and audit requirements.

Build the calendar from the actual accounting period and current official filing systems. Record the form, legal due date, filing channel, receipt and responsible professional for each obligation.

Do not send accounts, tax, employee, beneficial-ownership or filing records through a general enquiry. Independent provider scope, fees and any referral compensation are disclosed before consented transfer.

Review status: Editorially reviewed 20 September 2026 against the current DBD, Revenue Department, SSO, DOE and BOI service routes. Next scheduled review: 20 December 2026. Build deadlines and filing duties from the entity's current facts and the responsible authority's live instructions.

Professional review: Not performed. No qualified Thai accounting, tax, employment, corporate or legal approval.
