Key Takeaways
- Every Thai company must state a registered office address in Thailand at incorporation. That part has not changed.
- What changed is DBD Order 4/2568: once an address is already shared by five or more registered companies, the DBD now wants a signed landlord consent letter plus a title deed or lease agreement, not just an address on a form.123
- A virtual office is generally fine for company registration itself. Whether it holds up for VAT registration is genuinely disputed, and one side of that dispute is a virtual-office provider.
- The signed order is dated 15 December 2025. Its widely repeated 1 January 2026 start date could not be confirmed anywhere.
In Detail
The requirement itself is not new
A Thai limited company has always had to give a registered office address as part of incorporation. It is a basic filing requirement, not a policy choice, and no source disputes it. What has changed in 2026 is not whether you need an address. It is what you now have to prove about it.
DBD Order 4/2568: the five-company trigger
The Department of Business Development’s Order No. 4/2568 requires registrars to cross-check a submitted registered address against Thailand’s national civil registration database.2 Where that address has already been used by five or more existing registered companies or partnerships, the applicant must now submit a consent letter from the property owner or authorised occupant, together with documentary evidence of the right to use the premises, a title deed if the property is owned, or a lease agreement if it is rented.3
That threshold applies in three places, not just at first incorporation: address-change filings and branch-office registration are caught the same way.4 A company that moves office, or a foreign company adding a Thai branch, faces the same documentation test as a brand-new registration.
Why this lands squarely on virtual and serviced offices
Sharing one address across dozens of client companies is not an incidental feature of a virtual or serviced office product. It is the product. A building that hosts thirty registered companies clears the five-company threshold many times over, on day one, for every single one of them.
One law firm’s commentary on the order makes the practical point directly: as an address approaches the five-company mark, the landlord or the virtual-office provider itself may become reluctant to keep issuing consent letters or sharing title documents, since each new letter puts their own name on record against a growing list of tenants.5 The provider’s incentive and the applicant’s need for a straightforward filing start to pull in different directions right at the point most Singapore owners are trying to keep setup simple.
**The 1 January 2026 effective date.** DBD Order 4/2568 is a signed instrument dated 15 December 2025. That date is solid. The 1 January 2026 effective date attached to it everywhere in commentary could not be confirmed against the order itself or any other primary instrument, across two separate research passes. Treat the order as real and dated, and treat its start date as reported, not established.
**Whether a virtual office survives VAT registration.** This is genuinely open, not just under-researched. One source states plainly that the Revenue Department has, in practice, rejected some VAT applications tied to virtual-office and co-working addresses, and that it typically conducts, or reserves the right to conduct, a site inspection before issuing the VAT certificate (Por Por 20).6 That same source also says a virtual office with proper documentation "typically passes" inspection. It is worth naming plainly that this source is a virtual-office provider, so its favourable framing carries a commercial interest in the answer. No primary Revenue Department statement of policy was found either way. Raise this with your accountant before you commit to an address, rather than assuming either outcome.
**Work permits, on a single source.** One source reports that the Department of Employment assesses whether a registered address is a genuine place of work, and that a registered-office or mail-forwarding-only service is reported as insufficient to support a Non-Immigrant "B" business visa application at Immigration, even though the same address can still support VAT and Social Security registration and, in some cases, a work permit.7 This was not independently corroborated. It is plausible and worth checking case by case, not a settled rule.
The practical decision
For DBD company registration on its own, a virtual or serviced office address is generally accepted, provided the supporting documents are in order. If all you need at incorporation is a compliant address and you are not registering for VAT or sponsoring a work permit from that address in the near term, a virtual office is a reasonable risk.
The calculation changes the moment VAT registration or a work permit enters the picture. If you expect to cross the THB 1.8 million VAT threshold, or to sponsor a foreign employee’s work permit from this address, do not treat the cheapest virtual-office package as settled. Ask your provider directly whether they will still issue a signed consent letter and share their title deed or lease once your filing goes in, and ask your accountant how the same building has fared at Revenue Department inspection recently. A single address decision can pass one authority and fail another, three separate authorities in fact: the DBD, the Revenue Department, and the Department of Employment can each look at the same address and reach a different conclusion.
Keep the lease agreement or title deed and the signed consent letter regardless of which way you go. The bank will ask for the same paperwork when you open the corporate account, which is opening a bank account.
Before you lock in a registered address
- Roughly how many other companies are already registered at this address? If it is anywhere near five, ask about the consent letter before you sign anything.
- Can the landlord or provider actually produce a title deed or lease agreement, not just an invoice for the address service?
- Will you need to register for VAT within the first year? If yes, ask your accountant how this specific building has fared at a Revenue Department site inspection before you commit.
- Will you sponsor a work permit from this address? If yes, check separately whether it will support the Non-Immigrant “B” visa application at Immigration, not only the work permit itself.
- Have you kept a copy of the lease or title deed and the consent letter somewhere you can find them? The bank will ask for them again.
