What is the deadline for filing financial statements in Thailand?

The shareholders' ordinary meeting must approve the audited statements within four months of the financial year end, and the DBD submission then follows within one month after that approval. In practice the whole chain — closing, audit, meeting, filing — runs to that five-month window.

Our books are kept monthly. Why is closing a separate job?

Monthly bookkeeping records transactions; closing adds the adjustments that make the statements accurate — accruals, depreciation, provisions, inventory valuation and the notes TFRS requires. These are estimates and judgements, so they are prepared and reviewed as a separate exercise.

Can you close the year if another firm did the monthly work?

Yes, provided the ledger and supporting documents are complete. We reconcile the balances the audit will test before preparing the statements, and flag anything that cannot be evidenced.

What does year-end closing cost?

It depends on the state of the monthly books and the transaction volume. Send the latest trial balance and we reply with a written quote — the review costs nothing.

Year-end financial statement closing in Thailand

Year-end closing converts twelve months of bookkeeping into the financial statements a Thai company must have audited, approved by shareholders and filed with the Department of Business Development. When the monthly books were kept properly, closing is a scheduled exercise of weeks; when they were not, closing is where the problems surface — which is why we start with a trial-balance review before quoting.

What this service covers

Year-end adjustments and close

Accruals, prepayments, depreciation, provisions and inventory adjustments posted so the statements reflect the real position under Thai Financial Reporting Standards.

Financial statements in the DBD format

Statement of financial position, profit or loss, changes in equity, cash flows and notes prepared in the structure the DBD e-filing system accepts.

Audit coordination

Closing schedules and supporting evidence prepared for the independent CPA, and audit queries answered by the team that closed the books.

DBD e-filing and PND.50 reconciliation

After the shareholders' meeting approves the statements, they are filed with the DBD and the annual tax return is reconciled to them line by line.

How the engagement runs

1. Trial balance review
We review the current trial balance and flag the accounts that need correction before closing starts — this review is free and sets the quote.
2. Correction of the monthly books
Posting errors and unreconciled balances are fixed in the monthly records first, so the closing adjustments sit on clean data.
3. Closing and statement preparation
Year-end adjustments are posted and the full statement set is drafted for management review before the auditor sees it.
4. Approval and filing
After audit sign-off and shareholder approval, the statements are filed with the DBD within the statutory window.

Deadlines, rates and filing formats change. Confirm current requirements with the Revenue Department, the Social Security Office and the Department of Business Development, or ask us to confirm them for your case before you rely on a date.

Common situations we are hired for

First year-end after incorporation

The first close sets the opening balances for everything that follows; doing it properly is the cheapest audit preparation there is.

A year-end that is already overdue

Late DBD filing carries penalties and marks the company's public record. We schedule the closing, audit and filing to regularise the position in the shortest defensible order.

Group reporting in a non-Thai format

For an overseas parent, the Thai statutory statements are mapped to the group reporting package so consolidation uses the audited figures.

Monthly books kept by someone else

We close and prepare statements from another accountant's ledger after reconciling the balances that the audit will test.
