Do You Need a Visa and Work Permit to Do Business in Thailand?

Yes. In most cases, foreigners need both a valid visa and a work permit to engage in any kind of business activity in Thailand legally.

Registering a Thai company doesn’t automatically entitle you to work or run the business. If you intend to attend meetings, sign contracts, manage operations, or supervise staff, Thai law considers this “work,” so a work permit is legally required.

When You Do Need a Visa and Work Permit:

  • You’re a director or managing partner of a Thai company
  • You plan to work full-time or part-time in the business
  • You will sign documents, meet clients, or oversee daily operations
  • You’re being paid a salary or dividends and being actively involved

When You Might Not Need One:

  • You’re a passive shareholder or investor, not performing any active duties
  • You visit Thailand only occasionally for board meetings and do not engage in daily work
  • You manage your company remotely from abroad

⚠ Important: Even informal work (like replying to business emails or working from your home) may be considered illegal without the correct visa and permit. Thai immigration has become stricter in recent years, especially in 2024-2025.

With that being said, if you’re doing anything beyond passive investment, it’s safest and legally required to obtain both a business visa and a work permit. Let’s take a closer look at how to get a Work Permit for Foreigner Entrepreneurs in Thailand in 2025.

Can You Work for Your Own Company in Thailand?

Owning a Thai company doesn’t automatically give you the right to work in it, at least not without the proper documentation. According to Thai law, owning a business and working in it are two separate activities. Foreigners who are actively involved in their company’s operations must obtain both a Non-Immigrant “B” Visa and a Work Permit, even if they are the sole owner.

 

⏩ Roles That Require a Work Permit

The following roles are considered “work” under Thai law and require a valid work permit:

  • Managing Director or CEO
  • Authorized Signatory on official company documents
  • Operations Manager, salesperson, or project lead
  • Anyone who represents the company in meetings, signs contracts, or deals with government agencies

 

⏩ Owning vs Operating: The Legal Distinction

  • Owner/Shareholder: You may hold shares in a Thai company without living in Thailand or applying for a work permit, as long as you are not involved in operations.
  • Director: If you take part in decision-making, sign documents, or direct staff, Thai law considers you to be working, regardless of whether you’re drawing a salary.

 

⏩ What Happens If You Work Without a Permit?

  • Fines of 5,000 to 50,000 THB
  • Deportation and a 2-year ban on future permits in serious cases
  • Your company may also be fined 10,000-100,000 THB per foreign worker, face criminal charges and be blacklisted
  • Future visa and work permit applications may be rejected

 

Recent 2025 Enforcement Case: In April 2025, Thailand inspected over 500,000 foreign workers across 38,700 businesses and prosecuted 2,575 individuals under the Alien Working Act – many for taking jobs reserved for Thais or working without permits.

Business Visa vs. Work Permit: What’s the Difference and Which One Do You Need?

One of the most common sources of confusion among foreign entrepreneurs is the difference between a business visa and a work permit in Thailand. These are two entirely separate documents, and having one does not automatically entitle you to the other.

 

A Non-Immigrant “B” Visa allows you to enter and stay in Thailand for business-related purposes. It’s a visa category issued by Thai embassies or consulates abroad, and it’s often required before applying for a work permit. However, this visa alone does not grant you the legal right to work, even if your company is already registered.

 

To legally work and manage your business, you must also obtain a Work Permit issued by the Thai Department of Employment (DOE). This permit specifies your job title, employer and location of work. Without it, doing any work-related activities in Thailand, even if you are not receiving a salary, is considered illegal.

 

For example, if you enter Thailand on a Non-B visa to set up your company, you may attend basic bank appointments or view office spaces, but you cannot legally sign contracts, hire staff, or begin operating the business until you have the work permit.

 

Both documents are linked to your employing company. Your business visa and work permit must correspond. In other words, if your visa is sponsored by your company, your work permit must also be connected to that same entity.

 

You can learn more about the legal difference between the two directly from the Thai Department of Employment’s FAQ page, which clarifies that “any work done by a foreigner, whether with or without wages, requires a permit.”

Types of Business-Related Visas: Non-B, SMART Visa and LTR

Foreign entrepreneurs in Thailand have more than one visa option in 2025, depending on the nature of their business, level of investment and long-term plans. While the Non-Immigrant “B” Visa remains the most common choice, the SMART Visa and Long-Term Resident (LTR) Visa now offer flexible alternatives for qualified applicants.

 

Non-Immigrant “B” Visa (Business Visa)

This is the standard visa for foreigners who intend to do business or work in Thailand. It’s typically required before applying for a work permit and is issued in two common formats:

  • A single-entry visa (valid for 90 days)
  • A multiple-entry visa (valid for 1 year with 90-day stays)

 

To apply, you usually need a company sponsor. It can be either your own registered Thai business or a company inviting you to work with them. In 2025, Thai embassies still require a full set of corporate documents, including company registration, shareholder lists and sometimes proof of capital or employment contracts.

 

SMART Visa

The SMART Visa program was created to attract skilled professionals, tech entrepreneurs and investors in targeted industries like fintech, robotics and health tech. SMART Visa holders can work in Thailand without a separate work permit and may stay for up to 4 years, depending on their category.

 

Key categories include:

  • SMART “S” – Startup entrepreneurs (must be part of an approved incubator or hold qualifying funds)
  • SMART “I” – Investors in targeted sectors
  • SMART “E” – Executives with experience in innovative industries
  • SMART “T” – Talent in science, engineering, or digital tech fields

 

Unlike the Non-B visa, the SMART Visa has stricter eligibility criteria, including salary thresholds, educational background, or BOI-supported company affiliation. Details are available from the SMART Visa portal.

 

Long-Term Resident (LTR) Visa

Launched in 2022 and still gaining popularity in 2025, the LTR Visa is designed for wealthy individuals, foreign experts and entrepreneurs with long-term plans in Thailand. Business owners may qualify under the “Wealthy Global Citizen” or “Work-From-Thailand Professional” categories if they meet the income and investment thresholds.

 

LTR visa holders benefit from:

  • 10-year visa validity
  • Streamlined 90-day reporting (once per year)
  • Permission to work legally in Thailand (digital work permit)
  • Fast-track services at immigration and airports

 

To qualify, applicants typically need:

  • Proven income of USD 80,000+ per year
  • Health insurance or sufficient assets
  • Thai company involvement or global employment

How to Get a Work Permit in Thailand Step-by-Step in 2025

Once you acquire a valid Non-Immigrant “B” visa or SMART Visa, the next step to legally work in Thailand is applying for a Work Permit. The DOE issues this permit under the Ministry of Labour and is legally required for almost all types of work, including running your own company.

Here’s how the process works in 2025:

Eligibility Requirements

To sponsor a foreigner for a work permit, a Thai company must meet the following conditions:

  • Registered capital of at least 2 million THB per foreign employee (or only 1 million THB if the foreigner is married to a Thai national)
  • At least 4 full-time Thai employees per work permit
  • The company must be properly registered with the Ministry of Commerce and have a valid VAT registration

(Companies under the Board of Investment (BOI) may be exempt from the first two listed requirements.)

Documents Required

  • Approved company name reservation form via the Department of Business Development (DBD)
  • Memorandum of Association (MOA)
  • Articles of Association
  • List of shareholders with their identification details
  • Directors’ details and consent to act as directors
  • Proof of the registered business address, such as a lease agreement
  • Power of Attorney (if filing through a representative)

Application Process

  1. Prepare and submit documents to the local DOE office
  2. Pay application fee (ranges from 750 THB to 3,000 THB depending on permit length)
  3. Wait for approval. Processing usually takes 7 to 10 business days
  4. Once approved, receive the blue work permit book (digital alternatives are being piloted but not yet universal)

The work permit is generally valid for 1 year, renewable as long as the visa and company remain compliant. The place of work and job title must match exactly what the permit states. Any changes require a formal amendment.

For more details, the DOE foreign labor section provides official updates on rules and forms.

Tip: Applying inside Thailand requires that your Non-B visa be converted into an extendable visa first. Not all embassies issue this directly, so plan your visa and permit timeline carefully.

Visa Extensions, TM30 and 90-Day Reporting in Thailand

After receiving your visa and work permit, your responsibilities don’t stop there. To maintain legal status while living and working in Thailand, you must follow ongoing immigration requirements, including visa extensions, address reporting (TM30) and 90-day check-ins.

 

Extending Your Non-B Visa

A Non-B visa initially grants you a stay of up to 90 days. If you’re working in Thailand or operating your own company, you can apply for a 1-year extension through the Thai Immigration Bureau.

 

To extend your visa:

  • You must have an approved work permit
  • Your company must be in good legal standing (correct staff ratios, taxes, and capital)
  • You’ll need to submit financial statements, tax documents, and employee records

 

Once approved, you receive a 1-year stay extension, which is renewable annually. Please note that this extension is tied to your work permit, meaning that if one becomes invalid, the other may be affected.

 

TM30 Reporting: Address Notification

Thai law requires that landlords or property owners notify immigration when a foreigner stays at their property using Form TM30. If you’re renting an apartment or condo, the building staff often handles this, but you are still legally responsible.

 

You can submit the TM30:

 

Failure to file or update TM30 may result in fines when applying for a visa extension or re-entry permit.

 

90-Day Reporting

All foreigners staying in Thailand for over 90 days on a long-stay visa must report their presence every 90 days using Form TM47.

 

How to report:

 

Reports must be submitted within 15 days before or 7 days after the 90-day mark. Missing the window may result in a fine of 2,000 THB, and repeat violations can lead to visa problems.

Visas for Family Members of Foreign Entrepreneurs in Thailand

If you plan to relocate to Thailand with your family, you will need an additional visa for your spouse, children, or other dependents. While Thailand offers pathways for dependents to stay legally, there are clear rules on what they can and cannot do, especially regarding working or studying.

 

Non-Immigrant “O” Visa (Dependent Visa)

The most common option for spouses and children is the Non-Immigrant “O” visa, issued based on dependency. This visa is typically granted to family members of someone holding a Non-B or SMART Visa.

 

To apply, you’ll need:

  • A valid Non-B or SMART visa holder as the sponsor
  • Proof of relationship (marriage or birth certificate, translated into English)
  • Passport copies and photos
  • Company registration and employment documents of the sponsor

 

Once approved, the dependent visa is usually issued for 90 days initially, with the option to apply for a 1-year extension (matching the sponsor’s visa duration).

 

For SMART visa holders, bringing dependents is much simpler, and the rules are not as strict. For example, spouses can work without a separate work permit, provided the job is not on Thailand’s prohibited occupations list.

 

Education Visas for Children

If you have school-age children, you may also apply for a Non-Immigrant “ED” visa for them, especially if they are attending an international school or language institute in Thailand. The school will usually assist with the paperwork.

 

Requirements include:

  • Official enrollment letter from the school
  • Academic plan and curriculum
  • Tuition payment confirmation
  • TM30 address registration

 

Can Dependents Work in Thailand?

In most cases, dependents on an “O” visa cannot work unless they independently qualify for a work permit and a Non-B visa. The only exception is under the SMART Visa, where the spouse may be eligible to work without obtaining a separate permit, subject to approval.

 

If your spouse plans to work, it’s often easier to apply separately for a Non-B visa tied to their employer or business.

Top Legal Mistakes Foreigners Make When Starting a Business in Thailand

Starting a business in Thailand as a foreigner comes with unique legal requirements, and failing to follow them can result in fines, visa problems, or even deportation. In 2025, Thai authorities continue to tighten enforcement, especially in popular business hubs like Bangkok, Phuket and Chiang Mai. Here are the most common legal mistakes you can make when starting your first business in Thailand and how to avoid them.

 

  1. Working Without a Permit

Many new entrepreneurs believe they don’t need a work permit to manage their own company. This is false. If you sign contracts, hire staff, manage operations, or even supervise projects, you’re considered to be “working” under Thai law. This requires both a valid visa and a work permit.

 

  1. Using Nominee Shareholders

Thai law restricts foreign ownership in many industries to 49%. Some foreigners try to bypass this using Thai “nominee” shareholders. This is illegal, and authorities are actively cracking down. Violations can lead to criminal charges, company closure and deportation.

 

  1. Relying Too Heavily on Visa Agents

While some visa agents provide helpful services, others offer shortcuts that may not be legal, such as fake employment contracts or false addresses. If your visa or work permit is based on incorrect information, you are liable. Always verify what agents submit on your behalf.

 

  1. Operating Under a Tourist or Education Visa

Using a tourist visa to run a business, attend meetings, or manage staff is illegal, even if you’re not being paid. Education visas are also not meant for business activity. With recent crackdowns, immigration officers routinely check social media, office listings and company registration data more often to identify unauthorized work.

 

  1. Failing to File TM30 and 90-Day Reports

Many foreigners forget to update their addresses via form TM30 or submit 90-day reports. While these seem like minor administrative steps, repeated violations can raise immigration flags that affect their ability to renew their visas or apply for re-entry permits.

 

It is advisable to use Thailand’s official immigration portal to submit reports or check your visa status. Do not rely solely on third parties!

Conclusion

Doing business in Thailand as a foreigner is fully possible in 2025, as long as you follow the legal requirements. That means securing the correct visa, obtaining a valid work permit and staying compliant with immigration and labor regulations.
