Thailand Company Registration for Foreigners: Steps & Timeline

Can foreigners start a business in Thailand?

Yes. Foreigners can own and register Thai companies in most activities. The question is never whether you can register, but what you can own and do once registered: Thailand's Foreign Business Act restricts foreign participation in a list of service and trading activities, while manufacturing and export-oriented activities are generally more open.

A company is classed as foreign by shareholding, so where an activity is restricted, the lawful routes to foreign majority are BOI promotion, a Foreign Business Licence, or a genuine joint venture. Nominee shareholding to disguise foreign control is illegal and will surface at the worst possible time — at sale, at audit or in a dispute.

• Unrestricted activity — a standard Thai company may be enough
• Restricted activity needing foreign control — BOI or a Foreign Business Licence
• A genuine Thai partner — often the fastest lawful structure

Decide these things before you file anything

Registration goes smoothly when the decisions behind it are already made. Each of the following feeds directly into the filings.

• Exact business activity, written down — it drives licences, ownership and work permits
• Shareholders and the ownership split, including any Thai partners
• Registered capital, set against work permit and licence requirements, not just the statutory minimum
• Directors, company name options (prepare two or three) and a registered office

The registration steps, in order

The sequence below is how a standard Thai private limited company is registered. Steps three onward are where a good local professional earns their fee.

• Reserve the company name with the Department of Business Development (DBD)
• File the memorandum of association with shareholder and capital details
• Hold the statutory meeting and adopt the articles
• Register the company and receive the company affidavit
• Obtain the tax ID and register for VAT where applicable
• Open a corporate bank account — expect in-person meetings and documentation
• Apply for activity-specific licences and register for social security

How long it takes and what it costs

Registration itself is a matter of weeks when the paperwork is right. The realistic end-to-end timeline for a trading business — company, tax, bank account, licences and staff permissions — runs months, not weeks.

Costs divide into official government fees (modest and published) and professional fees (variable and significant). Scope drives price: an unrestricted activity with no licences is the cheapest case; a licensed or BOI-promoted activity is not. Get two or three written quotes with a defined scope rather than one verbal estimate.

After registration: what to keep on top of

Registering is the easy part. Thai companies live under monthly and annual obligations, and foreign-owned companies get proportionally more scrutiny.

• Monthly VAT and withholding filings, and annual audited accounts
• Social security registration and contributions for staff
• Work permit rules: registered capital and Thai employment ratios under the standard route
• Immigration reporting for foreign directors and staff

The three mistakes we see most

First, incorporating before defining the activity — the activity determines ownership, licences and permits, so work backwards from it. Second, nominee arrangements to sidestep ownership rules, which unwind expensively. Third, undercapitalising to save on filings, then struggling with work permits, licences and bank credibility later.
