Withholding Tax for Personal Income Tax (PIT)

Certain incomes are subject to withholding taxes at source, this includes employment incomes. Employers are obligated to withhold tax, file tax return, and remit the withheld amount to The Revenue Department of Thailand.

Social Security Fund Contribution

The Social Security Act of 1990, amended in 1999, requires employers to withhold social security contributions from the monthly wages of employees and remit to the Social Security Fund. The fund is used to compensate employees for sickness, maternity, disability, death, child allowance, old-age and unemployment. The current rate of contribution for both the employee and employer’s share is 5% of the employee’s salary and the maximum contribution amount is THB750 per month.

Thailand Corporate Tax Rates

Corporate Income Tax (CIT) is levied on companies carrying out business activities in Thailand and companies not carrying out business activities in Thailand but deriving certain income from Thailand. A company is considered a taxpayer in Thailand if it is incorporated under the Thai jurisdiction or incorporated under foreign jurisdiction and carrying out business activities in Thailand or deriving Thailand-sourced income.

The standard corporate income tax rate in Thailand is 20% of the company’s net income, however, rates may vary depending on the type of taxpayer.

Corporate Income Tax for Small Business

Companies are considered a small business or company when it has a paid-up capital less than THB 5 million at the end of each accounting period. These companies are taxed at a rate between 0% and 20%.

Employees’ Income Tax in Thailand

As an employer, it is important, and a responsibility, to understand and facilitate your employee’s tax obligations in addition to your own.

Taxpayers of personal income tax (PIT) in Thailand are categorized into two groups: resident and non-resident. An individual is considered a resident for tax purposes when he or she has resided in Thailand for a period of more than 180 days or periods aggregating more than 180 days in one tax year. Resident taxpayers are taxed on any Thailand-sourced income as well as a portion of foreign income brought into Thailand. Non-resident taxpayers are taxed only on Thailand-sourced income.

Employment income of both resident and non-resident are taxed on the same progressive scale of up to 35% on taxable income.
