Thai Company Capital Requirements for a Foreigner’s Work Permit

The headline number is real, but its legal function is often misstated. The Ministry of Labour's published consideration criteria say that a Thai juristic person with THB 2 million of paid-up registered capital may be considered for one foreign worker. The same page lists THB 3 million of remitted foreign investment per foreign worker for a foreign juristic person and states a maximum of 10 workers under that criterion.

That wording matters. A capital threshold is part of the screening framework, not a purchase price for a permit. A company can clear the capital figure and still have a weak application if the proposed job does not fit the business, the supporting records are inconsistent, or the foreigner's status and qualifications do not line up with the route being used.

A foreign director is a good example. The title alone does not settle the issue. The employer needs a coherent story across the corporate records, the actual business, the job description and the work the person will perform. The role must also be one that a foreigner may lawfully undertake.

The same discipline is needed when adding a second foreign employee. Doubling a capital number is only an initial sense check; it does not answer the staffing, immigration or employer-category questions. BOI-promoted projects, foreign juristic persons and other special routes are assessed under different frameworks, so the standard Thai-company rule should stay in its lane.

A company's registered capital tells you what has been recorded in the corporate structure; the work-permit criterion refers specifically to the paid-up amount. That distinction is easy to lose in shorthand advice. Merely registering THB 2 million does not, by itself, prove that the employer satisfies a paid-up-capital test.

Nor is the capital a bond paid to the government for the privilege of employing a foreigner. The official OSOS FAQ says the company may use the money to run the business. What changes is the evidence burden: the employer should be able to support the capital figure with records that are consistent with the company's real financial position and activity.

A mature company will often have a richer paper trail. OSOS points to items such as the company affidavit, evidence relating to capital, the current corporate income-tax return and financial statements. A newly incorporated company may not yet have a full annual history, so the evidence will naturally look different; that is not the same thing as saying that a new company is automatically ineligible.

This is why a generic instruction to make one bank transfer and keep one receipt is too simplistic. Capital formation, accounting records and subsequent business use need to fit the company's actual circumstances. The practical test is consistency across the documents, not whether one isolated paper shows the desired number.

The familiar 2:1:4 ratio is not simply an agency slogan. An official OSOS FAQ describes a standard scenario as THB 2 million of investment capital, one foreign worker and four permanent Thai workers. The mistake is treating that shorthand as if it were a single universal rule governing every employer and every immigration basis.

Work authorization and permission to stay are connected operationally, but they are not the same approval. A company may be dealing with the Department of Employment for the work permit while also relying on a Non-B status or an extension process under Immigration. When those two tracks are compressed into one checklist, people start attributing every staffing condition to the work-permit decision itself.

For a conventional small Thai company, the OSOS ratio is a sensible planning baseline, provided the Thai headcount is genuine. Payroll, social-security records and tax filings may form part of the broader evidence that the employer is operating as a real business, depending on the application and the company's history. Creating nominal jobs purely to satisfy a number is not a legitimate substitute for actual employment.

Special regimes change the analysis. BOI-promoted projects have their own foreign-personnel approval framework, while a foreign juristic person is already treated differently on the Ministry's capital criterion. So the staffing question should follow the route selection, not precede it.

The file behind a work-permit application describes an employer, not just a capital figure. For a Thai company, current corporate registration records and the shareholder list help establish who the employer is and how it is constituted. A foreign juristic person has a different evidence trail, including the authority to operate and documentation of funds remitted into Thailand.

Financial records then have to support the corporate story. Department of Employment materials for company employers refer, depending on the case, to financial statements, tax returns and VAT records. An established business will naturally have more historical evidence than a new company. The absence of several years of accounts is therefore not the same as a failed application; inconsistency between the documents that do exist is the more obvious problem.

Staffing evidence can matter as part of the same picture. Payroll information, social-security contributions and tax records may be relevant to showing that Thai and foreign employees are real and that the employer is functioning as claimed. The exact list varies by route and circumstance, so it is better to think in evidence categories than to copy an old universal document checklist.

The foreign employee's side of the application must also connect. Passport and immigration status, qualifications, experience, job title and job description should form a credible match with the company's activity. If the title is senior but the business records and duties do not support that role, a correct capital number does not fix the mismatch.

For current submissions, the Department of Employment operates the e-WorkPermit system. Its official portal includes online work-permit applications for eligible foreign workers. Older DOE document lists remain useful for understanding the kinds of evidence authorities have historically required, but they should not be presented as a paper-only workflow that still governs every case.

A BOI-promoted employer starts from a different question: does the promoted project need this foreign position? BOI's published procedure requires the company to seek approval for the position first, explaining its responsibilities, headcount, duration and necessity. Only after the position is approved does the company place a named foreign expert into it, with qualifications and experience that match the approved role. The work-permit application then follows through the Department of Employment or the relevant provincial office.

That sequence is why standard non-BOI ratios should not be pasted onto a BOI case. Under the Investment Promotion framework, BOI determines the approved positions, number of foreign personnel and duration according to the project. Visa status, permission to stay and work authorization remain distinct administrative steps even when they are coordinated through the promoted-project process.

BOI also imposes its own personnel criteria. In a July 2025 official update, it announced that manufacturing businesses with 100 or more employees must maintain at least 70% Thai nationals. The same update introduced monthly income thresholds for foreign personnel seeking BOI-related visa and work-permit privileges: at least THB 150,000 for executive-level personnel and THB 50,000 for expert-level personnel. Those figures should be applied only where the relevant BOI category and position fall within the revised criteria.

So BOI is not shorthand for 'no capital or staffing rules'. It replaces the ordinary route with a индивидуально для проекта approval framework that asks different questions. IEAT and other special statutory bases can also operate differently, but each needs its own current rules rather than a borrowed non-BOI checklist.

Scenario one is a Thai Limited Company hiring one foreign director. The Ministry's THB 2 million paid-up-capital criterion is the obvious first filter, but it should be tested alongside the company's Thai workforce, the director's actual duties, immigration status and the evidence the employer can produce. A newly formed company will have a shorter record by definition, so current formation and operating documents carry more weight than nonexistent historic accounts.

Scenario two is the same company adding a second foreign manager. Capital planning may suggest another THB 2 million under the standard criterion, and the OSOS staffing ratio becomes relevant as a planning benchmark. Yet the second role still needs its own rationale. More capital does not cure an incoherent job description or an employer record that cannot support the additional foreign headcount.

Scenario three is a fresh company with declared and paid capital but little or no turnover history. That is not automatically a dead end. The file may instead depend on incorporation records, evidence of paid-up capital, current contracts, licenses where applicable, tax registrations and a credible business setup. The weaker case is an empty shell whose only strong-looking number is the capital line.

Scenario four is an operating company with an established Thai team and a tax trail. It can usually show more corroborating evidence—accounts, payroll, social security and tax records—so the application is easier to assess as a real employment situation. The permit still depends on the employee and route; history improves evidence, not entitlement.

Scenario five is a BOI-promoted company. Start with the promoted project and approved foreign position, then apply the current BOI personnel criteria. Multiplying the non-BOI capital and Thai-headcount shorthand may be irrelevant to the actual approval sequence.

One weak pattern is capital that exists only as a registration number. Where the criterion is paid-up capital, the employer needs records that support that status. Conflicting corporate and financial figures can turn a seemingly clean THB 2 million number into the main question in the file.

Another is a job title that does not fit the business. Calling someone a director, expert or manager does not make the role self-explanatory. Authorities can compare the company's activity with the proposed duties and the person's qualifications; a capital threshold cannot compensate for a role that looks detached from the employer's real operation.

Staffing can also expose inconsistencies. A Thai headcount that appears nominal, unstable or unsupported by payroll and social-security evidence may undermine the picture of a genuine employer. Fabricated employment arrangements are not a legitimate way to satisfy a planning ratio.

A different class of errors comes from collapsing separate procedures. A work permit is not the same approval as a Non-B visa or an extension of stay. BOI promotion is also not automatic clearance for any foreign employee: the project and position still pass through BOI's foreign-personnel process.

Finally, old procedure guides can age badly. The Department of Employment now operates e-WorkPermit, so a historic paper checklist should be treated as background, not as the current interface. Strong applications are coherent across the employer category, capital, staffing, business activity, position and the foreigner's status.
