Change a Registered Office in Thailand

Classify the move before choosing the process

The DBD office-change guide distinguishes a move within the same province from a move to another province. A change of province can involve the memorandum and the corresponding approval process. A new operating location may instead be an additional branch, rather than a replacement of the head office.

Confirm the legal address, administrative district, postcode, unit and building details. Check whether the proposed premises can support the intended activity and the evidence needed by the relevant authorities. The lease or owner’s permission is part of the evidence file; it is not a universal guarantee that every registration or licence will be accepted.

Organise the premises evidence

• Current company documents and the proposed complete address in consistent Thai and English forms.
• Lease, owner consent and the property or occupier evidence required for the application.
• Map, photographs and location details where requested by the authority.
• Decision documents appropriate to the type of move and the company’s articles.
• Tax registration details for the existing and proposed establishments.
• List of operating licences, bank mandates and contracts that use the old address.

Agree the move date with the landlord, operations team and advisers. Record when the old premises cease to be used and when activity starts at the new location. Different authorities may ask different questions about those dates.

Review VAT notifications before the move

For a VAT-registered business, the Revenue Code provisions on changes to VAT registration distinguish changes in registered particulars, relocation and additional establishments. Some actions require advance notice. Do not assume that a DBD address amendment automatically updates the VAT registration or that every notification is due only after the move.

Prepare the relevant VAT change process with the responsible adviser before setting the operational cutover. Confirm branch identifiers, establishment certificates and any arrangements for combined or separate returns. The VAT guide explains the wider registration and return workflow.

Update commercial documents and systems

List invoices, receipts, purchase orders, supplier master data, customer contracts, bank records, insurance and delivery arrangements. Agree the effective date for the new address in each system and preserve the history of documents already issued. Do not overwrite an old invoice merely to make every historical record display the new address.

Test the billing and accounting systems after the change. Check the legal name, tax number, branch designation and address on a sample document. Tell suppliers which details should appear on future invoices and maintain a record of invoices requiring correction.

Coordinate employees, access and operational records

Review payroll and social-security employer records, employee work locations and foreign-worker documents where relevant. Update the storage location and access arrangements for accounting and statutory records. Ensure notices and official correspondence can still reach the responsible person during the transition.

For a business with several locations, use the branch guide to separate the head office from operating outlets. Review any BOI, customs or sector-specific location conditions through the relevant specialist process.

Account for the move itself

Keep rent deposits, advance rent, fit-out, equipment transfers, moving costs and lease termination amounts identifiable. Their accounting and tax treatment depends on the facts and applicable policy. Maintain an asset movement list and reconcile any refunds from the old landlord. A move can also expose old balances that should be reviewed rather than carried forward indefinitely.

Agree whether management needs a one-off relocation-cost report or a new branch reporting dimension. Compare costs on a consistent basis so a temporary overlap in rent does not become an unexplained change in operating performance.

Close the move checklist

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.

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.

Keep the updated registrations, submitted notifications, sample invoice, bank confirmation, supplier communications and premises evidence together. Mark outstanding items explicitly. The corporate-change checklist provides a practical tracking format.
