Payroll Tax in Thailand: What You Need to Know

Payroll tax is a vital aspect of the global taxation system, and Thailand is no exception. For organizations operating in Thailand or seeking to establish a presence, knowing payroll tax legislation is vital to maintaining compliance with local laws.

This article gives a complete description of payroll tax in Thailand, its purpose, who is responsible for paying it, and how it fits into more expansive concerns like Thailand company formation or establishing a representative office in the country.

What is Payroll Tax?

Payroll tax is a government-mandated fee levied on salaries and wages paid to workers. It is used to support public services such as healthcare, social security, and unemployment compensation. Payroll tax is typically collected straight from employee earnings and augmented by contributions from the employer. In Thailand, payroll taxes are intimately related to the social security system and personal income tax regulations.

What Does Payroll Tax Pay For?

Payroll taxes contribute to many social welfare initiatives in Thailand. These include:

• Social Security Contributions: Employers and workers in Thailand are obliged to pay to the Social Security Fund (SSF), which supports benefits including unemployment insurance, healthcare, and maternity benefits. 
• Workmen’s Compensation Fund: Employers pay to this fund to offer financial help for workers who are injured or incapacitated due to workplace incidents.
• Personal Income Tax: Employers in Thailand are responsible for withholding personal income tax from employees’ salaries and remitting it to the Revenue Department. 

These taxes and contributions help maintain a safety net for workers while assuring access to important services. 

Who Pays Payroll Tax in Thailand?

Both employers and workers share the duty of paying payroll tax in Thailand, while contributions to the Social Security Fund (SSF) are shared equally between employers and employees.

Employers are required to deduct income tax from employees’ salaries and remit it to the authorities. Additionally, they must contribute 5% of each employee’s wage (capped at THB 750 per month) to the Social Security Fund (SSF), with employees contributing an equal amount. Employers are also responsible for contributions to the Workmen’s Compensation Fund, which is calculated as a percentage of the annual payroll and varies based on industry risk levels.

On the other hand, employees are individually liable for income tax, which is deducted based on progressive tax rates ranging from 0% to 35%. They must also contribute 5% of their salary (capped at THB 750 per month) to the Social Security Fund (SSF), matching the employer’s contribution.
