How Much Capital Is Required to Register a Company in Thailand-and How to Raise It Safely

When registering a company in Thailand, many investors become confused by the concept of “paid-up capital”: How much money must actually be deposited? Where should the funds come from to ensure compliance and stability? And what common pitfalls exist in the process? Without clarity on these questions, delays in company registration may occur-or worse, complications may arise later with bank account opening, visa applications, and even tax filings.

Basic Rules on Registered Capital for Thai Companies

Thailand’s Civil and Commercial Code and the Foreign Business Act do not prescribe a uniform mandatory minimum registered capital. In practice, however, the amount must be determined holistically-considering the company type, industry nature, and business plan. For an ordinary limited company (Co., Ltd.), registered capital is declared voluntarily by shareholders, denominated in Thai Baht (THB) at registration, and does not require an official capital verification report. Nevertheless, the declared amount must be genuine and fully realizable.

Once registered, the capital forms the statutory basis for the company’s liability to third parties; therefore, misrepresentation is strictly prohibited. If it is later discovered that capital has not been contributed or has been withdrawn improperly, shareholders may face joint and several liability.

How to Safely Fulfill Paid-Up Capital Requirements

1. Full payment of registered capital is not required prior to registration. Instead, it must be completed within the timeframe stipulated in the company’s Articles of Association-commonly within 30 to 90 days after incorporation.

2. The source of funds must be clear and traceable. We recommend transferring funds from a personal overseas bank account directly into the newly established Thai corporate bank account, clearly indicating the purpose as “Registered Capital” or “Share Capital Contribution” in the transfer memo.

3. Funds may be remitted in foreign currency but must be converted into THB at the prevailing bank exchange rate upon receipt. The bank will issue an official foreign exchange conversion certificate-a critical document required for subsequent tax reporting.

4. Avoid using third-party payments, cash deposits, or undocumented transfers from related parties. Such practices raise red flags regarding fund authenticity and may jeopardize BOI promotion applications or work permit approvals.

5. Upon completion of capital contribution, a licensed Thai accountant must issue a formal “Capital Contribution Confirmation Letter.” Additionally, the company’s accounting records must be updated to reflect the paid-up capital under the appropriate equity account-ensuring full alignment between financial books and official commercial registration.

Common Misconceptions About Capital Contribution-and How to Avoid Them

1. Temporarily routing funds through another person’s account-only to withdraw them shortly thereafter-is a classic case of capital withdrawal (“capital flight”). Thailand’s Office of the Auditor General and Revenue Department have intensified scrutiny of such anomalous fund flows in recent years.

2. Using loan proceeds as registered capital is impermissible if the loan agreement explicitly states the purpose as “working capital” or “operational liquidity.” Doing so would constitute improper accounting treatment.

3. Contributing assets such as machinery or vehicles as non-cash capital requires formal valuation by a Thai government-accredited appraisal agency, followed by legal title transfer procedures. This process is both complex and time-consuming-therefore, it is generally discouraged unless absolutely necessary.

4. Making multiple small, staggered capital contributions to simulate full funding triggers automated bank monitoring systems that flag transaction linkages. Fragmented deposits often increase, rather than reduce, regulatory scrutiny.

How Registered Capital Interacts with Post-Registration Compliance

1. The size of registered capital directly affects the number of work visas a company may sponsor: typically, one visa quota for a foreign director or manager is allocated per THB 2 million of registered capital.

2. When opening a corporate bank account, most local Thai banks require submission of proof of capital contribution, along with the relevant clause(s) from the company’s Articles of Association specifying the method and timeline of capital contribution.

3. During the company’s first-year tax filing, a statement confirming capital contribution status must be submitted concurrently. Failure to meet the prescribed contribution deadline may disqualify the company from certain corporate income tax incentives.

4. For companies seeking Board of Investment (BOI) privileges, registered capital must meet the minimum threshold specified in the applicable BOI-promoted activity category-and full payment must be completed within six months of BOI approval, accompanied by formal verification documentation.

The above outlines the core logic and practical essentials concerning paid-up capital in Thai company registration. Should you have specific questions-or wish to explore further details-we strongly recommend engaging a local certified public accountant experienced in Thai corporate law and tax practice, who can conduct a tailored pre-registration assessment aligned with your business model and shareholding structure.
