How to navigate Thailand's tax system as an expat

Moving to Thailand? Your tax situation is about to change. This guide explains what you'll owe and how to file correctly.

Tax System Overview

Income Tax in Thailand

Thailand operates a progressive income tax system, meaning higher earners pay a higher percentage on their income above certain thresholds. The top marginal rate is 35%.

What Does This Mean in Practice?

On a gross annual salary of €90,000, you would pay an effective tax rate of approximately 6%, resulting in a net monthly income of approximately €6,267. This accounts for income tax and mandatory social contributions.

For context, the average monthly salary in Thailand is approximately €820.

VAT (Value Added Tax)

The standard VAT rate in Thailand is 7.0%. VAT is included in consumer prices and applies to most goods and services. Reduced rates typically apply to:

• Basic food items and groceries
• Medical supplies and pharmaceuticals
• Books and educational materials
• Public transport (in some cases)

Special Tax Regimes for Expats

Yes — Reduced rate. Thailand Elite Visa Tax Benefits: Reduced tax rates on foreign-source income

If eligible, these regimes can provide substantial savings during your initial years in Thailand. Always verify current requirements with a qualified tax professional, as rules change frequently.

Tax Filing Requirements

As a tax resident of Thailand, you are generally required to:

1. Register with tax authorities upon establishing residence
2. Obtain a tax identification number
3. File an annual tax return (deadlines vary)
4. Declare worldwide income if you are a tax resident
5. Report foreign bank accounts if applicable

Double Taxation

Thailand has double taxation agreements (DTAs) with numerous countries. These treaties determine which country has the right to tax specific types of income and help prevent you from being taxed twice on the same income. Before moving, check whether a DTA exists between Thailand and your home country.

Tax Tips for Expats

• Hire a local tax adviser familiar with expat situations during your first year
• Keep records of all income, deductions, and tax payments from day one
• Understand residency rules: most countries consider you a tax resident after 183 days
• Check for exit tax: some countries impose tax on unrealised gains when you leave
• Social security contributions are often separate from income tax and can add 10-20% to your total burden

Additional Data Points

Recent reports and expat sources provide these additional figures for Thailand:

• Thailand is not a tax haven. In Thailand, there are two main types of taxpayers — residents and non-residents. A resident is a person who resides in Thailand for more than 180 days in a calendar year, and a resident is liable to pay tax on any income earned in Thailand , as well as on a portion of any income that is brought into Thailand from overseas. However, a non-resident is only subject to tax on income that is earned in Thailand.
• Income tax in Thailand is based on assessable income, which covers employment salary, professional fees, interests, dividends, and capital gains on securities, royalties, property rental, and income from consulting or contracting. Basically, most forms of earnings over THB 150,000 per year are taxable in Thailand.
• If you haven't spent all 180 out of 365 days in Thailand, you may still be able (and, in some cases, required) to obtain a TIN. This typically happens when you have potential tax liability in the country. In this case, you will need to present other documentation to prove your tax residence: proof of investment, papers showing intent to purchase property, etc.
• Tax residents are people who reside in Thailand for 180 days or more during a calendar year. Non-residents are those who spend under 180 days in the country during one calendar year.
• In summary, digital nomads or remote workers who spend less than 6 months in Thailand and work for employers overseas will not need to pay taxes in Thailand. Keep in mind this is not legal without a Thai work permit and the right visa.
• Note that when you are legally employed in Thailand, you will also need to make social security contributions. In the Thai social security system, the employee contributes 5% of the first THB 15,000 of their income. The employer will then match that contribution. Finally, the Thai government will also add a 2.5% contribution to your social insurance.
