Working legally in Thailand as a foreigner requires two things: a Non-Immigrant B (Non-B) visa and a work permit (ใบอนุญาตทำงาน, bai anunyat tamngan). Both are required — the visa alone doesn't permit you to work. This guide covers the full process from a Phuket perspective, including who actually needs a work permit and what it really costs.
Working in Thailand without a valid work permit is a criminal offence under the Thai Foreign Business Act. Penalties include fines of ฿5,000–฿100,000 and/or up to 5 years imprisonment. Deportation and blacklisting from Thailand can follow. This applies to any employment, including part-time, casual, or unpaid work that would normally be paid.

Who Needs a Work Permit in Phuket?
The legal answer: any foreigner performing work in Thailand for compensation — or that would normally attract compensation — requires a work permit. This includes:
- Employed by a Thai company or international company with Thai presence
- Running a Thai-registered business as a director receiving a salary
- Teaching at a school or language institute (including TEFL)
- Working in tourism (tour guide, hotel, dive instructor)
- Healthcare professionals (doctors, dentists, nurses)
- Lawyers and legal professionals
Remote Workers: The Grey Zone
Most remote workers in Phuket — people working for foreign employers or clients via laptop — technically require a work permit under Thai law. In practice, enforcement of this has been very limited for people genuinely working for overseas entities with no Thai employer. The introduction of the Digital Nomad DTV visa acknowledges this reality and provides a cleaner legal framework for remote workers, though even DTV doesn't formally provide a work permit for Thai-based employers.
If you work remotely for foreign clients from Phuket on a DTV, LTR Wealthy Foreign Talent, or similar visa — you're operating in a grey zone that is widely tolerated. If you receive income from Thai sources or Thai clients, you need a proper work permit.
How to Get a Work Permit in Phuket
Obtain a Non-Immigrant B visa
Work permits require a Non-B visa — you cannot apply on a tourist visa or exemption stamp. Apply at a Thai embassy abroad (or from within Thailand if changing visa type via the Non-B process). Your employer sponsor must provide a job offer letter.
Your employer prepares company documents
Your Thai employer must provide: company affidavit, list of shareholders, financial statements, tax registration, VAT registration, social security registration, and proof they have at least 4 Thai employees. This typically takes 1–2 weeks to prepare.
Prepare personal documents
Gather: passport (original + copy), Non-B visa copy, recent photo (1–2 inches), educational qualifications (diploma/degree, translated and legalised), employment contract, medical certificate from approved Thai doctor.
Submit application at Phuket Department of Employment
The Department of Employment office for Phuket is located in Phuket Town on Tilok Uthit 1 Road. Hours: Mon–Fri 08:30–16:30. Bring all original documents and sets of copies. Your employer or their representative should accompany you or submit on your behalf.
Wait for processing
Processing typically takes 7–14 business days. You'll receive a receipt letter confirming your application is under review. You can legally work from the date of submission in some circumstances — confirm with your employer's lawyer.
Collect your work permit booklet
Once approved, collect your blue work permit booklet (or digital version). Keep it with you at work at all times — you must produce it on request. The work permit is tied to your specific employer and job position.

| Document legalisation (if foreign docs) | ฿2,000–฿8,000 | Degree legalisation, apostille, translation |

The work permit process involves coordination between your employer's accounts, the Department of Employment, and Immigration. A local Phuket accountant or lawyer who specialises in work permits can prepare all documents correctly and submit on your behalf. Typical professional fees: ฿5,000–฿15,000 for the full process. Attempting it yourself without Thai language ability and familiarity with the process is very difficult.
Employer Requirements for Sponsoring a Work Permit
Not every Thai company can sponsor a work permit. The standard requirements for a Thai employer:
- Minimum 4 Thai employees per foreign work permit held
- Company registered capital of at least ฿2,000,000 per work permit (some authorities)
- Current tax and social security compliance
- Genuine business operations — shell companies without real activity face scrutiny
- BOI-promoted companies may have more favourable requirements
In Phuket, common employment sectors for expats with work permits include: international schools (BISP, UWC, HeadStart), hospitality and hotel management, property agencies, diving schools, and healthcare at Bangkok Hospital Phuket or Siriroj.
Minimum Salary Requirements
Thailand sets minimum monthly salary thresholds for foreign workers by nationality:
| Nationality | Minimum Monthly Salary |
|---|---|
| Europe, USA, Canada, Australia, Japan, etc. | ฿50,000/month |
| China, India, some other Asian countries | ฿25,000/month |
| Other developing countries | ฿18,000/month |
Your employment contract must show a salary at or above this threshold. Work permits are also tied to a specific job title and scope of work — you cannot perform tasks outside what's listed in your permit without amending it.
Professions Restricted to Thai Nationals
Certain occupations are legally reserved for Thai citizens only and cannot be performed by foreigners regardless of visa or permit status:
- Legal practice (licensed lawyer, solicitor in Thai courts)
- Accounting (signing off as a licensed Thai accountant)
- Architecture and civil engineering (licensed practice)
- Medical practice beyond approved scope
- Tour guide (this is enforced in Phuket — foreign tour guides have been fined)
- Driving for hire (taxi, motorcycle taxi, tuk-tuk)
- Manual labour / unskilled work
Running a Business: Thai Company + Work Permit
Many Phuket expats run their own Thai-registered company and obtain a work permit as a director-employee. This is common for property agents, consultants, and service businesses. The key requirements:
- Form a Thai limited company (Thai Ltd.) — minimum 3 shareholders, at least 51% Thai-owned unless BOI-promoted
- Ensure your company has at least 4 genuine Thai employees
- Pay yourself above the minimum salary threshold
- Maintain proper accounting and tax filings
The alternative is an American Treaty company (US-Thailand Treaty of Amity) which allows US citizens to own a majority or fully foreign-owned Thai company in most sectors. See our Working in Phuket guide for business setup options.
