Annual accounts, audit and tax filing are separate deliverables
Year-end closing reconciles the company's books and supporting evidence, records justified adjustments and produces financial statements. The auditor performs an independent examination and issues a report. Preparing the accounts does not replace that report, and obtaining an audit report does not itself complete the company's tax filings.
DBD financial statements and the Revenue Department's P.N.D.50 return draw on related information but follow different processes. Accounting profit may need tax adjustments. Treating the ledger profit as the taxable result without examining the underlying items can leave a material gap.
Identify the legal entity before setting a filing calendar
A Thai limited company, registered partnership, public company and foreign entity should not be assigned one undifferentiated checklist. Shareholder approval and the BOJ 5 shareholder list concern limited-company procedures; a partnership does not become subject to those procedures merely because it prepares annual accounts.
The DBD guide requires a limited company to present its statements for general-meeting approval within 4 months after year-end and submit them within 1 month after approval. Registered partnerships submit within 5 months after year-end. A limited company submits BOJ 5 within 14 days after the ordinary shareholders' meeting. Check current-period announcements before arranging approval and submission.
Limited companies require a licensed statutory auditor. A qualifying small registered partnership may fall within an exemption from audit under accounting law, but tax-law examination and certification obligations must be assessed separately. That exemption should not be described as freedom from every form of examination. Review capital, assets, income and current eligibility rules before selecting the appropriate professional.
For entities required to submit P.N.D.50, the Revenue Department states a general deadline of 150 days after the accounting period ends. Check any applicable filing extension and submission channel separately. This tax-return deadline is not the DBD financial-statement deadline.
Records needed for a reliable handover
- Prior-year statements and auditor's report, trial balance, general ledger, opening balances and unresolved items.
- All business bank statements, cash evidence, receivables, payables and director or bank loan records.
- Sales and purchase evidence, expenses, contracts, filed tax returns and payment receipts.
- Closing inventory with count records and an asset register showing acquisitions and disposals.
- Entity registration information, accounting period, authorised signatories and actual approval documents.
An opening trial balance alone does not establish that every earlier transaction is supported. Identify gaps and reconcile the transfer from the previous accountant. Missing receipts, contracts or meeting records must not be replaced with invented retrospective documents.
Resolve reconciliation questions before audit
Match bank records to the ledger and review outstanding customer and supplier balances. Separate director funds from company funds. Check inventory and assets against evidence rather than assuming an old spreadsheet remains accurate. An unsupported expense is not automatically removable from the books or deductible for tax.
VAT-registered businesses should compare accounting revenue with relevant VAT returns and explain differences in timing or transaction treatment. A difference is not automatically a breach; matching totals do not prove that every underlying entry is correct. Refer judgement-sensitive matters to the responsible professional with the supporting facts.
Control approval, submission and proof of acceptance
Agree who prepares, checks, audits and signs. Arrange approval documents appropriate to the entity, submit through the prescribed channels and retain the acceptance receipts and tax-payment evidence. A file upload by itself is not confirmation that the authority has accepted a complete submission.
If an error is found after signing or filing, assess its significance and effect on the accounts, tax return and approval records with the relevant professionals. Do not edit the financial statements and reuse the old audit report without review. Filing authority also does not automatically grant bank-transfer authority or permission to use another person's credentials.
No trading income does not mean no closing work
A dormant business may still have capital, loans, expenses or outstanding obligations. Determine its continuing accounting and submission duties even when trading has stopped. Formal dissolution and liquidation are distinct processes; ceasing to send returns is not a substitute.
For overdue years, lost records or a changed accounting period, disclose the full history before commissioning the work. Scope the reconstruction and any corrective filings separately. We do not promise that penalties disappear or that every authority will accept incomplete evidence.
Ask for an itemised scope, not an assumed all-inclusive service
Tell our staff the entity type, year-end, VAT status, transaction volume, previous accounting arrangement and outstanding periods. Identify bookkeeping reconstruction, statement preparation, auditor coordination, approval papers, DBD submission and P.N.D.50 filing separately in the quotation. Contact our team for a quotation; the engagement determines which tasks are included.
Questions from company owners abroad
Can we appoint ILC when another firm kept the books?
Start with the prior accounts, opening balances and available records. Our staff assess the handover and missing work before confirming the scope. Do not send bank or filing passwords or one-time codes through ordinary messages.
Does an audited statement prove the tax return was filed?
No. Request the filing acceptance and any payment evidence separately. Accounts, audit and corporate tax submissions are connected but distinct deliverables.
Do partnerships follow the company AGM checklist?
Do not assume so. Establish the entity type and applicable accounting, examination and tax obligations before setting approval and submission steps.
