If you’re an expatriate living and working in Thailand, understanding your personal income tax obligations is essential. Whether you’re a resident or a non-resident, you may be subject to Thai taxation depending on your income sources. In this guide, we break down everything you need to know about personal income tax in Thailand as an expat.
Who Needs to Pay Personal Income Tax in Thailand?
Thailand’s tax system distinguishes between residents and non-residents:
- Residents (those who stay in Thailand for 180 days or more in a calendar year) must pay taxes on all income earned in Thailand, as well as any foreign income brought into Thailand within the same tax year.
- Non-residents are taxed only on income earned from Thai sources.
Regardless of your residency status, you must apply for a personal income tax ID if you earn taxable income in Thailand.
What Income is Taxable?
Thailand’s Revenue Department classifies assessable income into eight categories:
- Employment income – Salaries, wages, and employer-provided benefits (e.g., stock options, rent-free accommodation, tax-absorbed income).

- Royalties – Earnings from intellectual property rights, including patents and copyrights.
- Investment income – Dividends, interest on bank deposits, capital gains, and bonuses from company acquisitions or dissolutions.
- Rental income – Earnings from leasing out properties.
