Taxation in Thailand: Complete Guide for Expats

Thailand has become the number one destination for expats in Southeast Asia. Tropical climate, rock-bottom cost of living, incredible food, ultra-fast internet... The country ticks every box. On the tax side, things are interesting too: a territorial taxation system, progressive rates starting at 0%, and an LTR visa offering a 17% flat tax for qualified professionals.

In this guide, we cover everything you need to know about Thai taxation: income tax brackets, foreign income rules, LTR visa, cost of living, banking and daily expat life. If you're considering relocating to Thailand, this is your starting point.

1. The Thai Tax System: Overview

The Thai tax system is based on progressive rates ranging from 0% to 35%. Income is expressed in Thai baht (THB). For reference: EUR 1 equals approximately THB 38.

The Thai Revenue Department manages the entire tax system. The fiscal year matches the calendar year, and tax returns must be filed by March 31 of the following year.

Tax Residency

You become a Thai tax resident if you spend 180 days or more per year in the country. Note that this is 180 days, not 183 as in most countries. As a resident, you are taxed on Thai-source income and, since 2024, on foreign income remitted to Thailand.

2. Income Tax Brackets

Here are the progressive rates applicable to resident individuals:

• 0 to THB 150,000 (0 to EUR 3,950): 0%
• THB 150,001 to 300,000 (EUR 3,950 to 7,900): 5%
• THB 300,001 to 500,000 (EUR 7,900 to 13,150): 10%
• THB 500,001 to 750,000 (EUR 13,150 to 19,740): 15%
• THB 750,001 to 1,000,000 (EUR 19,740 to 26,300): 20%
• THB 1,000,001 to 2,000,000 (EUR 26,300 to 52,600): 25%
• THB 2,000,001 to 5,000,000 (EUR 52,600 to 131,600): 30%
• Above THB 5,000,000 (EUR 131,600+): 35%

Worked Example

Take a freelancer earning THB 2,000,000 per year (approximately EUR 52,600). After standard personal deductions (THB 60,000), here is the calculation:

• THB 0-150,000 bracket: EUR 0 in tax
• THB 150,001-300,000 bracket: THB 7,500
• THB 300,001-500,000 bracket: THB 20,000
• THB 500,001-750,000 bracket: THB 37,500
• THB 750,001-1,000,000 bracket: THB 50,000
• THB 1,000,001-1,940,000 bracket: THB 235,000
• Total: THB 350,000, approximately EUR 9,210
• Effective rate: approximately 18%

That is significantly less than the 30-45% a similar profile would pay in France. To compare with other destinations, check our ranking of countries with the lowest taxation.

3. Territorial Taxation and the 2024 Rule Change

Historically, Thailand operated a pure territorial taxation system. In practice: foreign-sourced income was only taxed if remitted to Thailand in the same year it was earned. Many expats simply waited until the following year to transfer their funds.

What Changed in 2024

Since January 1, 2024, the rule has evolved. Foreign-sourced income remitted to Thailand is now taxable regardless of the year it was earned. The one-year deferral workaround is gone.

In practice, for a French expat in Thailand:

• Thai-source income: always taxable at progressive rates
• Foreign income remitted: taxable since 2024, regardless of timing
• Foreign income not remitted: still exempt (the territorial principle remains)

This change mainly affects expats who live off foreign income and transfer it to Thailand. For those who structure their finances carefully, territorial taxation remains an advantage. Read our article on tax mistakes to avoid when expatriating to plan ahead.

The France-Thailand Tax Treaty

France and Thailand have signed a double taxation treaty. Income taxed in one country is not re-taxed in the other, with a tax credit mechanism. An important point to check if you retain French-source income (rental income, dividends, etc.).

4. The LTR Visa: 17% Flat Tax

The Long-Term Resident (LTR) visa, launched in 2022 by the BOI (Board of Investment), is Thailand's flagship program to attract foreign talent and investors. It offers a 10-year stay with significant tax benefits.

The 4 LTR Visa Categories

• Wealthy Global Citizen (wealthy retirees): passive income of USD 80,000+/year or USD 250,000+ investment in Thailand. Foreign income exemption.
• Wealthy Pensioner: pension of USD 80,000+/year or USD 40,000+ with USD 250,000+ investment. Foreign income exemption.
• Work-from-Thailand Professional: income of USD 80,000+/year (or USD 40,000+ with a master's degree or IP). 17% flat tax on Thai income, foreign income exemption.
• Highly Skilled Professional: income of USD 80,000+/year in a targeted sector. 17% flat tax on Thai income.

LTR Visa Benefits

• 10-year stay (renewable)
• 17% flat tax on Thai income (professional categories)
• Foreign income exemption (retiree/investor categories)
• Digital work permit included
• Fast-track immigration (no more endless queues)
• Simplified annual reporting (instead of every 90 days)

For eligible profiles, the LTR is clearly the most attractive option. Check our page on the best digital nomad visas to compare with other countries.

5. Corporate Tax and VAT

If you set up a company in Thailand, here are the main taxes to know:

Corporate Income Tax

The standard rate is 20% on net profits. Reductions exist for SMEs:

• Net profit up to THB 300,000: 0% (exempt)
• Net profit from THB 300,001 to 3,000,000: 15%
• Above THB 3,000,000: 20%

Important: setting up a company in Thailand as a foreigner is regulated by the Foreign Business Act. In most sectors, a foreigner can hold a maximum of 49% of the share capital. Exceptions exist through investment treaties and BOI programs.

VAT

The VAT rate is 7% (temporarily reduced for years, the statutory rate being 10%). This is one of the lowest rates in Asia. Companies with annual turnover exceeding THB 1,800,000 (approximately EUR 47,400) must register for VAT.

Capital Gains

Capital gains on SET-listed shares (Stock Exchange of Thailand) sold through a licensed broker are exempt. Other capital gains are taxed as ordinary income (progressive rates 0-35%).

6. Cost of Living in Thailand

This is Thailand's knockout argument. The cost of living is among the lowest in the world for a high level of comfort. Bangkok remains cheaper than most European capitals, and Chiang Mai is even more affordable.

• Rent (studio/1-bedroom in central Bangkok): EUR 400-600/month
• Rent (same in Chiang Mai): EUR 200-350/month
• Local meal (street food or simple restaurant): EUR 1.50-3
• Nice restaurant meal: EUR 10-20
• Fiber internet: EUR 15-25/month (200 Mbps average)
• Transport (BTS/MRT in Bangkok, pass): EUR 30-40/month
• Private health insurance: EUR 60-120/month
• Coworking space: EUR 80-150/month

Compared to Paris where a similar budget easily exceeds EUR 2,500, the purchasing power gain is considerable. For more details, check our Thailand country page.

7. Banking and Finances

Opening a bank account in Thailand is possible but not always straightforward. Procedures vary from one branch to another, even within the same bank.

Main Banks

• Bangkok Bank: the largest, relatively open to foreigners
• Kasikorn Bank (KBank): popular, good mobile app
• SCB (Siam Commercial Bank): decent service, extensive network

What You Need to Open an Account

• A long-stay visa (non-immigrant B, O, O-A, or LTR)
• Passport + copy
• Certificate of residence (available from your embassy in Bangkok)
• Sometimes proof of employment or a letter from your company

For international transfers, Wise remains the most cost-effective solution. Traditional SWIFT transfers work but with higher fees. The Thai baht (THB) is a stable and easily convertible currency.

Cryptocurrencies

Thailand regulates cryptocurrencies through the Thai SEC. Local platforms like Bitkub allow buying and selling Bitcoin and other cryptos. Capital gains on crypto are taxed at 15% (withholding tax).

8. Digital Nomad Life in Thailand

Thailand has been the favorite playground of digital nomads for years. And for good reason: fast internet, minimal cost of living, active international community.

Bangkok vs Chiang Mai

Bangkok is a metropolis of 10 million people. You will find everything there: skyscrapers, temples, gigantic malls, intense nightlife and a legendary street food scene. It is the ideal city if you enjoy urban energy and need an international airport within reach.

Chiang Mai, in the north, is the other digital nomad HQ. Quieter, greener, more affordable. Mountains replace skyscrapers. The freelance community is tight-knit with numerous coworking spaces (Punspace, CAMP, etc.) and regular meetups.

Internet and Infrastructure

With an average speed of 200 Mbps, Thailand offers one of the best internet networks in Asia. 5G is deployed in major cities. Coworking spaces are numerous and affordable (EUR 80-150/month for unlimited access).

Time Zone

The time zone is UTC+7, which is +6 hours from Paris. If your clients are in Europe, you can work early mornings (7 AM in Thailand = 1 AM in France) or late afternoons (3 PM in Thailand = 9 AM in France). The time difference requires organization but remains manageable.

9. Pros and Cons

10. Health and Daily Life

Thailand's private healthcare system is world-renowned. Hospitals like Bumrungrad in Bangkok are global references in medical tourism. Care costs a fraction of European prices, often for equivalent quality.

• GP consultation (private hospital): EUR 20-40
• Private health insurance: EUR 60-120/month depending on age and coverage
• Full check-up: EUR 100-200

The public system is free but reserved for Thai citizens. As an expat, private health insurance is essential. Private hospitals in Bangkok often have French or English-speaking staff.

For daily life, Thailand offers a pleasant living environment. The country is relatively safe (safety score of 6/10), the food is excellent, and Buddhist culture creates a relaxed atmosphere. Administrative procedures (visa extensions, 90-day reports) can be tedious, but the LTR visa greatly simplifies life for those who qualify.

FAQ

Does Thailand tax foreign income?

Since 2024, yes, if you remit it to Thailand. Foreign income you keep abroad remains exempt (territorial taxation principle). Before 2024, only income remitted in the same year it was earned was taxed.

How much does the Thai LTR visa cost?

The LTR visa costs THB 50,000, approximately EUR 1,300. It is valid for 10 years and includes a digital work permit, fast-track immigration and simplified reporting. The main requirement is annual income of USD 80,000 or more.

Can a French freelancer live in Thailand legally?

Yes, the LTR visa "Work-from-Thailand" category is designed for this. If your income exceeds USD 80,000/year (or USD 40,000 with a master's degree), you can legally work from Thailand with a digital work permit included.

What is the real cost of living in Bangkok?

A single person can live comfortably in Bangkok for approximately EUR 1,200/month all-inclusive. This includes a modern studio in the city center (EUR 500), food (EUR 300), transport (EUR 40), health insurance (EUR 80) and leisure. In Chiang Mai, expect EUR 800-900.

Does Thailand have a tax treaty with France?

Yes. The double taxation treaty between France and Thailand prevents being taxed twice on the same income. A tax credit mechanism applies. This is an important point if you retain French-source income (rental income, pensions, dividends).
