News & Update

For purposes of taxation, anybody who had lived in Thailand for more than 180 days is considered a resident of the country. Thailand residents are required to pay taxes on all income earned within and outside Thailand. Non-residents or those who have stayed in Thailand for less than 180 days per year will only be required to pay taxes on the income earned only within Thailand. Even those without a work permit but earn income in Thailand are not exempt from paying taxes.

To begin with, any expat working in Thailand must have his own tax ID number. This can be issued by the tax office after presenting passport or ID card. You will also need to justify the reason for needing a tax ID number. 

Personal Income Tax

All earnings that are considered to be assessable are categorized as Personal Income Tax. This includes non-cash payments such as accommodation or the use of a car. Personal Income Tax is classified as follows:

• Income from employment
• Income from a position held
• Income from royalties or dividends
• Income from rental arrangements
• Income from construction work
• Income from any business 

Deductible Expenses and Allowances

Taxpayer may deduct the Deductible expenses and allowances from his assessable income before applying the tax rate. This will lower the taxpayer’s tax base. In essence: 

Taxable Income = Assessable income less deductions (expenses) less allowances

A person completing a tax return will start with the assessable income amount less deductions such as expenses, then deduct any personal allowance. The remaining amount will be the amount that will be subject to tax. 

Personal Allowances

The following personal allowances are allowed in Thailand:

• Individual taxpayer : 30,000 Baht allowance
• Spouse of taxpayer (unemployed) : 30,000 Baht allowance
• Child allowance (below 25 years old, studying at educational institution, or a minor, or an adjusted incompetent or quasi-incompetent person) : 15,000 Baht allowance per child for up to 3 children maximum

Deductible Expenses

• Income from employment and income from copyright: deductible expenses = 40% of income but not exceeding 60,000 baht
• Income received from copyright and income from dividends and interests: No deductions are allowed.
• Income from rental of property: Actual and reasonable expenses, or a lump sum deduction of 10% to 30% depending on the type of rented property

• Income derived from business, commerce, agriculture, industry, transport, or any other income not specified above: Deductible expenses = Actual and reasonable expenses, or 65% – 85% depending on the types of income

Employers deduct a certain amount corresponding to withholding tax at source. This accumulated amount will be offset against the tax bill when filing a tax return, thus reducing the possibility of paying high tax amount.

The Thai tax year begins from 1^st January to 31st December and tax return should be filed with the tax office by 31^st March of the following year. Prompt payment of tax is encouraged in order to avoid incurring penalties for late filing and payment.
