Problems usually come later: the bank will not open an account, the visa does not match the business, or payments are put under review. In most cases the reason is a structure that was not planned before registration.<\/p>\n\n\n\n<p class=\"lead wp-block-paragraph\">Below: which company type fits which business, what to decide before you register, the documents you usually need, the steps in the right order and the mistakes we see most often.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">In short<\/h2>\n\n\n\n<ul class=\"wp-block-list glance\"><li><strong>Decide the structure before the paperwork.<\/strong> Your business model, ownership, visa and bank account must fit together.<\/li><li><strong>The company type depends on what you do.<\/strong> Many activities are restricted for companies with majority foreign ownership.<\/li><li><strong>Thai shareholders must be real.<\/strong> Nominee shareholders are illegal, and we do not arrange them.<\/li><li><strong>Registration is only the start.<\/strong> Tax, VAT, social security, a bank account, a work permit and accounting come after it.<\/li><\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Why the structure matters more than the registration<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Banks, immigration and the tax office look at the same chain: who owns the company, what it really does, where its money comes from and whether your visa matches your activity. If this chain is clear, the company works. If it is not, even legal income looks risky.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Company \u2192 activity \u2192 income \u2192 bank transactions.<\/strong> Every document you prepare should support this chain, not only pass the registration.<\/p>\n\n\n\n<figure class=\"wp-block-video\"><video controls preload=\"metadata\" src=\"https:\/\/www.unblockpro.asia\/wp-content\/uploads\/2026\/05\/9.-What-documents-do-you-need-own-thai-company_2.mp4\"><\/video><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">Which company type fits your business<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">There is no best company type, only the one that fits your real activity. These are the options most foreigners consider:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>Thai private limited company (Co., Ltd.).<\/strong> The most common structure. At least two shareholders. If foreigners hold 50% or more, the company is treated as foreign and cannot do restricted activities without a licence.<\/li><li><strong>Foreign-owned company with a Foreign Business Licence.<\/strong> Allows majority foreign ownership in some restricted activities, such as many services. It needs government approval, higher capital and time.<\/li><li><strong>BOI-promoted company.<\/strong> For qualifying activities such as manufacturing, technology and export. Up to 100% foreign ownership and easier visas and work permits, but the approval process is longer. <a href=\"\/en\/boi-services\/\">BOI promotion in detail<\/a><\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Under the Foreign Business Act, a Thai shareholder who only lends their name is a nominee, and nominee arrangements are illegal. If you need majority foreign ownership, the legal routes are a Foreign Business Licence, BOI promotion or an activity that is not restricted.<\/p>\n\n\n\n<figure class=\"wp-block-video\"><video controls preload=\"metadata\" src=\"https:\/\/www.unblockpro.asia\/wp-content\/uploads\/2026\/05\/36.-Why-difference-between-a-Thai-Company_2.mp4\"><\/video><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">What kind of business works well for foreigners<\/h2>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>Trading and import-export.<\/strong> Importing goods into Thailand, exporting Thai products and e-commerce. It works well when every payment is backed by contracts and invoices.<\/li><li><strong>Services and consulting.<\/strong> Marketing, IT, sourcing and agency work. Check early whether your service is restricted for foreign-majority companies.<\/li><li><strong>Manufacturing and projects for BOI.<\/strong> Factories, suppliers and technology projects often qualify for BOI promotion.<\/li><li><strong>Online business with Thailand as a base.<\/strong> Possible, but the most common risk is income received into a personal account with no company behind it.<\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Whatever you choose, the company must reflect what you actually do. A company that exists only on paper is one of the most common reasons for bank account reviews.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Three things to decide before you register<\/h2>\n\n\n\n<ol class=\"wp-block-list\"><li><strong>Your real business model.<\/strong> What the company does, who pays it and how the money will move.<\/li><li><strong>Ownership and control.<\/strong> Who the shareholders and directors are, and whether your activity is open to foreign ownership.<\/li><li><strong>Visa, work permit and banking.<\/strong> The company must be able to sponsor your visa and work permit, and its activity must make sense to the bank. <a href=\"\/en\/what-documents-you-need-to-open-a-business-visa-in-thailand\/\">Non-B visa and work permit guide<\/a><\/li><\/ol>\n\n\n\n<h2 class=\"wp-block-heading\">Documents you usually need<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Personal documents<\/h3>\n\n\n\n<ul class=\"wp-block-list\"><li>Passport copies of all shareholders and directors<\/li><li>Visa or entry stamp of foreign directors<\/li><li>Contact details and address of each person<\/li><\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Company registration documents (DBD)<\/h3>\n\n\n\n<ul class=\"wp-block-list\"><li>Company name reservation, with two or three name options<\/li><li>Memorandum of Association<\/li><li>Articles of Association and the minutes of the statutory meeting<\/li><li>Shareholder list with the number of shares<\/li><li>Director details and signing authority<\/li><li>Proof of paid-up capital, where required<\/li><\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Office and address<\/h3>\n\n\n\n<ul class=\"wp-block-list\"><li>Lease agreement or consent letter from the owner<\/li><li>House registration of the property and the owner\u2019s ID copy<\/li><li>Map and photos of the office<\/li><\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Business and banking documents<\/h3>\n\n\n\n<ul class=\"wp-block-list\"><li>Clear description of the business and how it earns money<\/li><li>Expected clients, suppliers and transactions<\/li><li>Source of funds for the capital and the first payments<\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Lists change, and each office and bank can ask for more. A shareholder company from abroad, for example a Chinese parent company, also needs its corporate documents legalised for use in Thailand.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Step by step<\/h2>\n\n\n\n<ol class=\"wp-block-list\"><li><strong>Check your situation.<\/strong> Business model, ownership, visa and banking, before any document is signed.<\/li><li><strong>Reserve the company name<\/strong> with the Department of Business Development (DBD).<\/li><li><strong>Prepare and sign the registration documents<\/strong> in Thai, with English versions for you.<\/li><li><strong>Register the company.<\/strong> Registration usually takes about a week once all documents are ready and signed.<\/li><li><strong>Register for VAT and social security<\/strong> when the business requires it, for example when turnover exceeds the VAT threshold or you hire staff.<\/li><li><strong>Open the business bank account<\/strong> with a clear explanation of the activity. <a href=\"\/en\/open-new-thai-bank-account\/\">Bank account opening help<\/a><\/li><li><strong>Arrange visas and work permits<\/strong> for foreign directors and staff.<\/li><li><strong>Keep it in order.<\/strong> Monthly accounting, tax filings, the annual audit and the shareholder meeting.<\/li><\/ol>\n\n\n\n<h2 class=\"wp-block-heading\">Common mistakes<\/h2>\n\n\n\n<ul class=\"wp-block-list\"><li>Registering quickly with a standard template and no plan for banking<\/li><li>Using nominee shareholders<\/li><li>Opening a company with no real activity, address or staff<\/li><li>Receiving business income into a personal account<\/li><li>Working in your own company on a tourist or DTV visa, without a work permit<\/li><li>Choosing the cheapest setup without checking ownership restrictions<\/li><li>Forgetting accounting and filings after the registration<\/li><\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">A typical situation<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Someone earns from online services or trading and receives the money into a personal Thai bank account. While the amounts are small, nothing happens. As the income grows, the bank asks for contracts, invoices and the source of funds, and there is no company to explain them. The account is put under review or frozen.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The fix is a real structure: a company with the right activity, a business account, a visa and work permit, and payments backed by documents. It works much better when it is built before the problem. If your account is already restricted, start there first. <a href=\"\/en\/unblock-thai-bank\/\">Frozen bank account help<\/a><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">For Chinese companies<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">If you are a company from China setting up a subsidiary, a factory or a supplier in Thailand, we have a separate guide with modules for registration, BOI and staff from China. <a href=\"\/en\/thailand-setup-chinese-companies\/\">Thailand setup for Chinese companies<\/a><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How we can help<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">We check your business model and the right company type, prepare the documents in Thai and English, coordinate the registration with our licensed partners and help you open the business bank account. Visas, work permits and accounting can be planned in the same process. We are not a law firm: licensed Thai lawyers and accountants handle the parts that require them. We cannot promise any decision, but we tell you honestly what is realistic before you pay.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Company setup from 31,900 THB, company with a business bank account from 89,900 THB, monthly accounting from 5,290 THB, all including 7% VAT. Government fees are separate. <a href=\"\/en\/company-setup-compliance-thailand\/\">Company setup and prices<\/a><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Questions we often hear<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Can a foreigner own 100% of a Thai company?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Only in some cases: with BOI promotion, a Foreign Business Licence or for activities that are not restricted. In an ordinary Thai company, foreigners usually hold up to 49%.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Can I use a Thai friend as a shareholder on paper?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">No. A shareholder who only lends their name is a nominee, and this is illegal. Thai shareholders must be real investors.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How long does registration take?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Usually about a week once all documents are ready and signed. Documents from abroad, legalisation, BOI and the bank account take longer.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Do I need a work permit to work in my own company?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Yes. Owners and directors who work in the company need a Non-B visa and a work permit.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Can I open the company remotely?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Often yes, with a power of attorney and documents signed and legalised abroad. Opening the business bank account usually needs the director in person.<\/p>\n\n\n\n<p class=\"note wp-block-paragraph\"><em>This article is general information, not legal advice.
