Key Deadlines for Submitting Financial Statements (Fiscal Year 2025)

        As we enter 2026, many business owners are now receiving notifications from their accounting firms to prepare their “year-end closing documents” for the 2025 fiscal year.
But did you know that the financial statement submission deadlines and forms differ between the Department of Business Development (DBD) and the Revenue Department (RD)?

       Even a one-day delay can result in fines ranging from THB 1,000 to 200,000.
So today, Nong Muang from ACC Consulting will summarize everything in simple terms — what needs to be filed, when, and what documents you should prepare.
