Does Thai labour law apply to a foreign executive on a home-country contract?

Where the executive works in Thailand for a Thai employer, the protections of Thai labour law apply regardless of the nationality of the employee or the law chosen in the contract. That includes severance based on length of service, notice rules and unfair dismissal claims.

If we use a fixed-term contract, do we avoid severance when it ends?

Usually not. The exemption from severance for fixed-term contracts is narrow: it covers specific work such as a special project outside the employer's normal business, occasional work, or seasonal work, each completed within two years under a written contract. An ordinary two- or three-year executive contract that is not renewed generally still attracts severance.

Is a housing or car allowance part of wages for severance?

Regular, fixed payments made as part of the pay for work can count as wages for calculating severance, depending on how they are structured and paid. Reimbursements of actual expenses usually do not. How the package is structured therefore affects both severance and tax.

Our foreign managing director is also a director of the Thai company. Is removing them as a director the same as ending their employment?

No. Directorship and employment are separate relationships. Removing someone as a director is a shareholders' decision registered with the registrar; ending the employment is a termination under labour law, with notice and severance. Handle both, in the right order.

What must happen to the work permit when employment ends?

The employer has notification duties when a foreign employee's employment ends, and the visa that depends on that employment ends with it. Plan the exit timeline around the work permit and visa so the executive has time to leave or change status lawfully.

Employing Expatriate Executives in Thailand: Contract Terms, Termination and Work Permits

Home-country contracts meet Thai law

Foreign executives are often hired on a contract drafted by the parent company, under its home law, with a secondment letter or a local contract added later. In Thailand, that structure does not remove Thai labour law. Where someone works in Thailand for a Thai employer, Thai labour protections apply — whatever the contract's governing law says.

The consequences surface at the end of the assignment: severance, notice, and sometimes an unfair dismissal claim from an executive who assumed they had none.

1. Who is the employer?

Structure	Practical position
Local hire by the Thai company	Thai company is the employer; Thai law governs
Secondment from the parent	Work permit still needed; the Thai entity is often treated as the employer for Thai purposes
Dual contracts / split payroll	Both contracts need to fit together; pay under both may count in severance and tax

Decide the structure deliberately and document it. An executive paid partly offshore and partly in Thailand, with no clear employer, is the hardest case to unwind.

2. Terms an expatriate contract should contain

Position and duties that match the work permit
Reporting line, including to the parent
Pay and allowances, stating which are wages and which are expense reimbursements
Tax treatment — who bears Thai tax, any equalisation. See Thai tax residency and foreign income
Benefits — housing, school fees, flights, insurance
Notice periods consistent with Thai law
Termination grounds and process
Confidentiality and IP
Post-employment restrictions, drafted to be reasonable in scope and duration
Equity awards, aligned with the plan rules. See employee share options and RSUs
Governing law and forum, recognising that Thai mandatory protections apply anyway

3. Why a fixed term rarely avoids severance

The fixed-term exemption from severance is narrow. It covers specific work — such as a special project outside the employer's normal business, occasional work, or seasonal work — completed within two years under a written contract.

A standard executive contract for a set number of years, doing the company's ordinary business, generally still attracts severance when it ends without renewal. Budget for it. See severance pay in Thailand.

4. The wage base

Severance is calculated on wages. Regular, fixed allowances paid as part of pay for work can count, depending on how they are structured. Reimbursements of actual expenses usually do not. A package designed with this in mind avoids arguments about what the severance should have been.

5. Director or employee — or both

Many expatriate managing directors are both directors of the Thai company and employees. These are separate relationships:

Removal as director is a shareholders' decision, registered with the registrar — see changing directors after registration
Ending employment is a termination under labour law, with notice and severance
Update the signing arrangement so the company is not left without an authorised signatory

6. Ending the assignment

Decide the reason and the process — resignation, non-renewal, restructuring, or dismissal for cause
Give notice or pay in lieu, and calculate severance on the correct wage base
Handle directorship changes and signing authority
Deal with equity awards under the plan rules
Complete work permit and visa steps and notifications
Agree handover, return of property and confidentiality
Document any settlement carefully

For disputes, see defending an employer in the Labour Court.

7. Work permit and visa

The work permit is tied to the employer and the position. When employment ends, the employer has notification duties, and the visa that depends on the employment ends too. Build the exit timeline around this so the executive can leave or change status lawfully. See visas and work permits in Thailand.
