BUSINESS IN THAILAND / CORPORATE HUB
Company registration is the beginning of an ongoing record and decision process. When directors, shareholders, premises, capital or business locations change, the company needs a coordinated plan for approvals, registrations, accounting and operational updates. These guides help you prepare that plan and identify the responsibilities to agree with the relevant advisers.

| Stage | Questions to answer |
|---|---|
| Define the transaction | What changes, for which legal entity, and on what intended date? |
| Review authority | Who can approve it and what do the articles or relevant permissions require? |
| Prepare evidence | Which documents, signatures, notices and payments support the change? |
| File and notify | Which authorities and counterparties need an update, and when? |
| Reconcile and retain | Do the registers, accounts and operational systems agree with the completed outcome? |
Corporate registration, accounting entries, tax notifications and bank mandates are separate workstreams. Agree which adviser prepares each document, who approves it and which authority receives it. The final file should include the signed approvals, submission evidence, updated records and any outstanding follow-up. A proposed change should not be treated as completed simply because a form has been drafted.
Use current registration instructions
Use the current Ministry of Commerce announcement on DBD Biz Regist when planning the filing channel. It states that partnership and private limited company registration applications move to DBD Biz Regist from 1 November 2026. Older manuals may still show counter-filing arrangements. Check current identity, signing and evidence requirements before scheduling the transaction.
The DBD duties guide is a useful official reference for ongoing responsibilities. Requirements differ by entity type and transaction. These pages focus primarily on Thai private limited companies; a public company, partnership or foreign-company branch may follow different rules.
What to prepare before requesting assistance
- Current company affidavit, memorandum, articles and relevant permissions.
- Shareholder register and existing resolutions relevant to the proposed change.
- A clear description of the intended outcome and effective date.
- Identity and authority of the people who will approve and sign.
- Relevant contracts, premises evidence, funding records or payment information.
- Known filing deadlines, disputes, authority notices or unresolved records.
Explain whether the change is planned, already effective or overdue. Do not alter the dates to fit a preferred timetable. If a deadline has been missed, the adviser needs the actual facts to assess the correct next step.
Keep the finance team involved
Corporate decisions can change the facts behind the accounts. Director balances, share capital, branch codes, leases, tax details and related-party information may all need review. Give the accountant the approved documents and completion evidence, not just a verbal description of the proposed change.
Connect this work with ongoing accounting, payroll and visa and work-permit guidance where relevant. The scope should distinguish accounting support from legal drafting, government fees and specialist approvals.
Build a continuing company record system
Use the statutory records guide to organise decisions and filings, the new director guide to establish responsibilities, and the corporate-change tracker to follow open actions. Clear ownership of the records reduces the risk of the same issue being rediscovered at the next audit or transaction.
Frequently asked questions
Does a corporate filing update all other agencies?
Do not assume so. Tax, banking, payroll, licences and immigration records may require separate actions.
Can a proposed change be treated as complete once documents are drafted?
No. Track the approvals, effective date, filing outcome and related updates. Drafting is only one stage.
Are all corporate changes covered by the monthly accounting package?
Only if the written scope includes them. Legal drafting, registration work, government fees and specialist reviews should be identified separately.
What if the company’s records are already inconsistent?
Preserve the existing evidence, identify the differences and obtain a review of the actual position before preparing further changes.
