From choosing the right entity structure to filing with the Department of Business Development — what foreign founders actually need to know before they start. The structure you pick on day one determines Foreign Business Act exposure, BOI eligibility, capital requirements, and whether you can later employ foreign staff or repatriate profits.
Start with structure, not forms
Registration itself is a filing exercise. The expensive mistakes happen earlier: picking a Thai limited company when BOI promotion was available, or committing to majority foreign shareholding without a legal basis to operate the intended activities. We map nationality, industry, staffing plans, and capital against the available structures before anyone drafts Memorandum and Articles of Association.
What the DBD actually needs
The Department of Business Development expects a coherent package: company name reservation, MoA and AoA, shareholder and director identity documents, registered address, and evidence of paid-in capital at the right moment. Incomplete or inconsistently translated documents are the usual reason a three-day filing turns into three weeks.
Capital evidence and bank timing
Registered capital must be evidenced, not merely declared. For foreign-majority companies, banks often want the entity already registered before they will open an account — while the DBD wants to see capital evidence as part of registration. Sequencing those two requirements is one of the most common stalls for first-time founders.
After the company exists
VAT and tax ID registration, social security, a corporate bank account, and — if you will employ foreigners — the staffing and capital ratios needed to sponsor work permits. Registration is day one. Treat the downstream steps as part of the same workstream or they will sit unfinished while the operating clock is already running.
