Yes, since January 1, 2024, all tax residents in Thailand must declare their foreign income repatriated in the year it is received. This rule applies regardless of your nationality. Income repatriated the following year remains, in practice, subject to declaration according to the instructions from the Thai Revenue Department.
The Thai Tax Reform: What Has Changed Since 2024
Before 2024, an informal rule allowed tax residents to repatriate foreign income the year after it was received without declaring it in Thailand. The Revenue Department ended this practice through instruction Por.161/2566, which took effect on January 1, 2024.
Now, if you are considered a tax resident in Thailand (meaning you stay there for 180 days or more in a calendar year), all foreign-source income that you repatriate to a Thai bank account — salaries, dividends, rents, capital gains — must be included in your annual income tax return.
⚠️ Important
This rule applies to anyone residing 180 days or more in Thailand, regardless of nationality: French, Belgian, Swiss, Canadian, Moroccan, Senegalese, or any other foreign national. Check your tax residency status with a local professional.
What Income Is Affected?
Foreign-source income subject to declaration in Thailand includes:
- Salaries and business income earned abroad and transferred to Thailand
- Dividends and interest from foreign accounts or investments
- Rental and real estate income generated outside Thailand
- Capital gains from the sale of assets (stocks, real estate) abroad
- Pensions and retirement income paid from your home country
- Online business income (freelance, e-commerce) earned abroad
💡 Good to Know
Income generated and kept outside Thailand, and not repatriated to a Thai account, is generally not taxable in Thailand. It is the effective transfer to Thailand that triggers the tax obligation.
Tax Treaties: Are You Protected Against Double Taxation?
Thailand has signed double taxation agreements with over 60 countries, including France, Belgium, Switzerland, Canada, Morocco, and Tunisia. If your home country has such an agreement with Thailand, you may benefit from a tax credit or exemption for income already taxed in your country.
Check if your home country is on the list of countries with agreements published by the Thai Revenue Department (rd.go.th).
✅ Practical Advice
Keep all proof of taxation in your home country (tax notices, tax certificates from the DGFiP, SPF Finances, AFC, Canada Revenue Agency, or your local administration) to justify a tax credit in Thailand.
How to Declare This Income in Practice?
The income tax return in Thailand (form PND 90 or PND 91) must be submitted between January and March of the following year (or April if filing online via the Revenue Department portal). Key steps include:
- Obtain or renew your Thai Tax Identification Number (TIN) from the Revenue Department
- Gather all documentation for repatriated foreign income (bank statements, transfer confirmations)
- Apply applicable deductions and allowances (personal, family, local life insurance)
- Submit the form online at efiling.rd.go.th or in person at a Revenue Department office
