Personal Income Tax in Thailand

Personal income tax in Thailand (PIT, Personal Income Tax) is a direct tax levied on personal income.

Tax Identification Number

In Thailand, a tax identification number is assigned to any taxpayer subject to income tax. Composed of 10 digits, this number is a liaison instrument between the taxpayer and the Thai Ministry of Revenue. A resident of Thailand is liable for income tax on the sources of income in Thailand as well as on the part of the income from foreign sources, unless a tax treaty provides for other provisions. This may be the case, for example for French pensions, as provided for in the convention between the government of the French republic and the government of the kingdom of Thailand for the avoidance of double taxation and the prevention of tax evasion in matters income taxes.

As a beneficiary of a scholarship, allowance or reward paid to him, essentially for pursuing studies or research, a scientific, educational, religious or charitable institution is not taxable in that other State on account of the sums it receives to cover its maintenance, study or training costs and on account of any sum consisting of remuneration for services rendered in that other State, provided that these services are related to his studies or training, or that they are necessary to cover his maintenance costs.

Taxable persons

There are two categories of taxpayers in Thailand: residents and non-residents. A resident taxpayer is a person who has resided in Thailand for a period totaling more than 180 days, in which case income collected in Thailand and income collected abroad are subject to tax in Thailand, subject to the provisions contained in the Franco-Thai tax treaty. For non-residents, only income from work in Thailand is subject to tax.

Taxable income

Taxable income covers all income in cash and in kind. Therefore, benefits granted by an employer or others, such as a house without paying rent or the amount of tax paid by the employer on behalf of the employee, are also considered taxable income.

Taxable income is divided into eight categories, as follows:

Income from personal services rendered to employers;

Income received from jobs, positions or services rendered;

Income from copyright, franchise, other rights, annuity or income in the nature of annual payments from a will or any other legal act or judgment; Income in the nature of dividends, interest on deposits with banks in Thailand, profit shares or other advantages of a legal company, legal partnership or mutual fund, payments received following a transfer of capital, a bonus, an increase in capital or holdings, gains from the merger, acquisition or dissolution of companies or legal partnerships, and gains from the transfer of shares or partnership funds;

Dividend tax credit

Any taxpayer who is domiciled in Thailand and receives dividends from a legal company or a company incorporated in Thailand is entitled to a tax credit of 3/7 of the amount of dividends received. In calculating taxable income, the taxpayer must increase his dividends by the amount of the tax credit received. The amount of the tax credit is charged to its tax debt.
