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.
Turning a year of transactions into filed statements
The year-end close converts twelve months of activity into a reviewed set of statements that can be approved by shareholders and filed with the authorities. The work runs in a fixed order: confirm completeness, post accruals and prepayments, record depreciation, translate foreign currency balances, recognise provisions where the reporting framework requires them, and then explain each resulting balance in a working paper.
What delays a close is almost never technical. It is a missing supplier invoice, a payment nobody can identify, an asset that cannot be located, or a shareholder balance with no agreement behind it. Because those items take time to resolve externally, we assess document condition first and issue the shortfall list immediately, so the recovery work happens in parallel with the accounting rather than after it.
Statutory deadlines then govern the rest of the timetable. Shareholders must approve the accounts within the period allowed after the year end, and the filing follows approval. Counting backwards from those dates produces the only realistic schedule for closing, auditing and convening the meeting — which is why we set the plan at the start of the process rather than negotiating it under pressure.
Dormant does not mean exempt
A company with no revenue still prepares and files statements; leaving the year unfiled exposes the directors and risks removal from the register.
Related-party disclosure
Balances and transactions with directors or affiliated companies must appear in the notes, supported by documentation that makes the terms explainable.
Late or backlog years
Where several years are outstanding we sequence them oldest first, because each year's closing balances become the next year's starting point.
Judgement areas that decide the final numbers
Most of a year-end close is mechanical, but a handful of judgements determine what the statements actually say. Whether a receivable is still collectible, whether stock is worth what it cost, whether a warranty or a legal exposure requires a provision, and how a foreign-currency balance is translated at the reporting date all change the result. Each of these needs a basis recorded in the working papers, because the auditor will test the reasoning rather than the arithmetic.
Presentation matters as much as measurement. Thai reporting requirements differ depending on whether the company applies the framework for non-publicly accountable entities or the full standards, and the notes expected under each are not the same. Related-party transactions, commitments, subsequent events and the basis of preparation all belong in the disclosures, and omitting them is the sort of finding that turns a straightforward review into a round of redrafting.
Comparability across years is the quiet requirement that catches companies out. Statements present the current year alongside the previous one, so a change in how something is classified must either be applied to both or explained in the notes. Reclassifying a cost from one heading to another without restating the comparative makes the trend meaningless and is exactly the kind of inconsistency a reviewer raises. We check the prior-year presentation before finalising this year's format.
The close is also the natural moment to correct the year's accumulated small errors. Items misposted between periods, expenses coded to the wrong account, and capital purchases treated as running costs are all easier to fix now than in a later restatement. We work through those adjustments in one documented pass so the audited figures and the tax computation start from the same reconciled ledger.
Accounting profit is not taxable profit
The two diverge through non-deductible items, depreciation differences and timing adjustments. We prepare the reconciliation between them so the return and the statements can be explained side by side.
Approval and filing dates
The shareholder meeting, the audited statements and the corporate return each have their own deadline. Missing one usually means missing the next, so the schedule is planned as a single chain.
Handling it in-house versus engaging us
Closing the year internally frequently ends with paying someone to review or redo it, because the judgemental steps — accruals, classification of shareholder balances, provisioning — determine the tax actually payable. Added to the hours consumed and the risk of statements being questioned, engaging a team that closes hundreds of sets each year is the cheaper starting point rather than the fallback.
Every engagement is quoted individually after we review your documents and agree the scope, so you know the fee and the timeline before any work starts. Send the details on LINE or by email and we will come back with a written proposal.
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.

Questions owners ask first
- 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.
