What is the Thai Tax Law about?

The Revenue Code is the comprehensive legal structure that regulates multiple aspects of tax in Thailand, as outlined in our Tax Guide for Foreigners in Thailand. It encompasses numerous tax-related rules and processes that provide a defined framework for the assessment, collection, and administration of various taxes. These include stamp duty, value-added tax, tax liability, particular business tax, and personal and corporate income tax.

This framework creates processes for determining tax amounts due, methods of collection, and the legal implications for different taxes. As a result, taxation in Thailand is kept transparent and uniform, ensuring that all taxpayers are aware of their responsibilities and enabling the government to effectively raise funds for public services and projects.

What are the different Income Tax Rates for Expats in Thailand?

Expatriates who qualify as employees under a business in this ‘Tax Guide for Foreigners in Thailand’ have the potential to benefit from a general tax arrangement. Specifically, they are subject to a fixed income tax rate of 15% for a period extending up to four years. This advantageous tax treatment simplifies the tax experience during their initial years of employment in Thailand. Below is a list of different tax categories that you should be familiar with:

  • Taxation Basis: Residents and non-residents in Thailand are taxed based on their Thailand-source income. Thai residents are liable for tax on foreign-source income only if the income is repatriated into Thailand in the year it is earned.
  • Residency Criteria: For personal income tax purposes in Thailand, an individual is considered a resident in Thailand if present for 180 days or more in a given calendar tax year.
  • Tax Filing Status: Married couples have the option to choose between joint or separate assessments for employment income. In cases where the wife earns passive income, it must be included in the husband’s return, even if the couple elects to file separately.
  • Taxable Income: Personal income tax applies to employment income, including most employment-related benefits. Profits from a trade or profession are generally taxed under the personal income tax regime. Dividends and interest are subject to source-based taxation at rates of 10% and 15%, respectively. 
  • Capital Gains Tax: Capital gains are exempt from personal income tax if the sold shares belong to a public company registered on the stock exchange of Thailand. Otherwise, gains are subject to the standard progressive personal income tax rates.
  • Tax Deductions and Allowances: Deductions are granted for various expenses, including insurance, mortgage interest, retirement or long-term equity plans, and charitable contributions, subject to specific restrictions. Personal allowances are available for the taxpayer, their spouse, children, and parents.

Things to consider as an Expat in Thailand

Tax in Thailand is a mandatory aspect for all residents, as detailed in this ‘Tax Guide for Foreigners in Thailand,’ irrespective of their residency status. Notably, the Value-Added Tax (VAT) at a standard rate of 7% applies to the majority of goods and services islandwide. Property and vehicle owners must also manage property tax and car tax, respectively. Expatriates in Thailand encounter personal income tax as a primary obligation, contrary to common misconceptions about tax law in Thailand.

Is Foreign-Earned Income Subject to Taxation?

Tax of income earned abroad in Thailand depends on the tax status and timing of repatriation. Non-tax residents are exempt from tax on foreign-earned income, but repatriation within the same calendar year requires taxes.

  • How to File Your Income Tax in Thailand: Filing for personal income tax in Thailand runs from January 1st to December 31st, with a filing period from January 1st to March 31st. The Thai Revenue Department facilitates online E-filing, but language constraints necessitate assistance for non-Thai speakers. Employers often aid in the filing process.
  • Other Tax Considerations: For those contemplating property purchases, awareness of specific business tax, transfer fees, withholding tax, and stamp duty is crucial. Thailand’s Value-Added Tax applies at 7% to goods and services. Inheritance tax, capital gains tax, and corporate taxes are also discussed, emphasising the absence of a specific tax on capital gains.
  • Withholding Tax in Thailand: Withholding tax, ranging from 0% to 35% applies to various income sources. Rates can be reduced or waived based on Double Taxation Agreements or specific Thai laws.
