The main types of payroll taxes in Thailand include personal income tax withholding, social security contributions, and provident fund contributions.
Personal Income Tax Withholding
Personal Income Tax (PIT) in Thailand operates on a progressive tax system with rates from 0% to 35%. Employers must withhold this tax from employee salaries based on projected annual income. The first THB 150,000 is tax-exempt, and tax increases through seven brackets, peaking at 35% for income over THB 5,000,000. PIT must be submitted to the Revenue Department using form PND.1 by the 7th of the following month, or by the 15th if filed online. Late or inaccurate filings may incur fines and 1.5% monthly surcharges on unpaid tax.
Social Security Contributions
Employers and employees each contribute 5% of the employee’s monthly salary to the Social Security Fund, capped at THB 750 per person. Contributions are based on a salary range of THB 1,650 to THB 15,000 and fund benefits like healthcare (1.5%), pension (3%), and unemployment insurance (0.5%). Employers must register workers and remit contributions using form Sor.Por.Sor. 1-10 by the 15th of the following month. Non-compliance can result in fines of up to THB 20,000, daily penalties of 2%, or even imprisonment.
Workmen's Compensation Fund
This is an employer-only contribution between 0.2% and 1% of payroll, based on the company’s risk classification. It funds compensation for work-related injuries, illnesses, or death. Employers must register with the Social Security Office and pay contributions alongside monthly social security filings. Penalties for non-compliance include fines and legal action.
Registering with Thailand Authorities
Businesses must first register with the Department of Business Development to obtain a company registration number. Then, register with the Revenue Department for a tax ID and as a withholding tax agent. Employers with at least one employee must also register with the Social Security Office. Foreign employees require work permits from the Ministry of Labor. Documentation includes company registration, director ID, and employee details.
Choosing a Payroll System
