Employment & HR in Thailand

What you need to know

Hiring in Thailand starts with a role-specific compliance check and a clear written employment agreement. Record the job, workplace, start date, pay and benefits, normal hours, probation arrangements, leave, notice, confidentiality and any ownership of work product. Contract terms and workplace policies cannot remove statutory minimum protections. Before making an offer, identify the current minimum-wage rate for the workplace and any covered business category, decide who can approve pay and overtime, and make sure personal-data collection is limited to what the hiring and employment process actually needs.

Working time, rest, holidays and leave should be configured in the HR and payroll systems rather than handled informally. Ministry of Labour guidance states that normal work is generally limited to eight hours a day and 48 hours a week, with lower limits for designated hazardous work. Employees are entitled to weekly rest and at least 13 traditional holidays including National Labour Day, while an employee who completes one uninterrupted year is entitled to at least six working days of annual holiday. Overtime, holiday work and premium pay depend on the work and circumstances. Once the workforce reaches 10 employees, the employer must issue Thai-language work rules within 15 days and keep them available at the workplace.

Payroll should connect the employment agreement, time and leave records, statutory deductions and the accounting ledger. Confirm whether each worker must be registered for social security, complete the relevant employer and employee processes with the Social Security Office, and keep contribution administration current. For tax, salary, wages, allowances and some employer-provided benefits can be assessable employment income. The Revenue Department method annualises periodic pay when calculating withholding, so payroll should capture taxable benefits and changes in pay rather than applying an unsupported flat percentage. Reconcile gross pay, deductions, net pay, withholding filings, social-security submissions and payment evidence every payroll period.

Foreign nationals require a separate check of immigration status, the work-authorisation route, the proposed occupation and the employer, role and workplace details covered by the permission. Do not assume a visa alone authorises work, and do not let a worker start while a required permission is outstanding. Track expiry dates and report changes through the applicable Department of Employment process. At termination, review notice, final pay, unused leave, statutory severance where applicable, social-security updates, tax documents and return of company property; lawful outcomes depend on service, contract terms and the reason for termination. A useful next step is to audit every active worker against a single register covering contract, pay, hours, leave, social security, tax and work-authorisation status.
