Buying property in Thailand as a French resident — or as a French citizen living in Thailand — has significant tax implications. Understanding the interaction between the French and Thai tax systems is essential for any French buyer.
How does the France–Thailand double tax treaty work?
France and Thailand signed a Double Tax Agreement (DTA) that prevents the same income from being taxed twice. Key provisions:
| Income Type | Taxed In | How It Works | |-------------|----------|-------------| | Rental income | Thailand (source country) | France grants a tax credit for Thai tax paid | | Capital gains on sale | Thailand (where property is located) | France does not tax Thai property gains | | Inheritance | Thailand (property location) | France may tax if resident — see below | | Interest income | Thailand (source country) | France grants tax credit |
How Tax Credits Work
If you pay Thai tax on rental income (5–35% progressive), you can claim a credit against your French income tax:
- Declare the Thai rental income on your French tax return
- Declare the Thai tax paid (from your Thai tax assessment)
- France applies a tax credit equal to the Thai tax paid
- If French tax is higher, you pay the difference; if lower, no additional French tax
How is Thai rental income taxed for French residents?
If You Are French-Resident
| Income Band (EUR) | French Tax Rate | Thai Tax Rate | Net After Treaty | |-------------------|----------------|---------------|------------------| | 0–10,777 | 0% | 0% (first 150K THB exempt) | 0% | | 10,778–27,478 | 11% | 5–10% | ~11% | | 27,479–78,570 | 30% | 10–20% | ~30% | | 78,571–168,994 | 41% | 20–25% | ~41% | | 168,995+ | 45% | 25–35% | ~45% |
Note: The 17.2% French social charges (prélèvements sociaux) may also apply to rental income, depending on your health insurance status.
If You Are Thai-Resident (Expat)
If you live in Thailand and are tax-resident there (183+ days per year):
- Thai tax applies to Thai-source rental income (5–35%)
- French tax does not apply to Thai-source rental income
- You file a Thai tax return annually
Does the French wealth tax (IFI) apply to Thai property?
France's Impôt sur la Fortune Immobilière (IFI) applies to real estate assets exceeding 1.3 million EUR.
| Asset Location | IFI Treatment | |----------------|---------------| | French property | Taxable (standard IFI rules) | | Thai property held directly | Taxable (included in IFI calculation) | | Thai property via Thai company | May be taxable (as real estate shares) |
Important: If your total global real estate assets exceed 1.3M EUR, your Thai property is included in the IFI calculation. The DTA does not eliminate IFI — it only prevents double taxation of income.
How are capital gains on Thai property taxed for French owners?
| Factor | France | Thailand | Net | |--------|--------|----------|-----| | Tax rate | 19% + 17.2% = 36.2% | 0% for individuals | 0% Thai, 19% French | | Holding period allowance | 6%/year after 5th year (full exemption at 22 years) | N/A | Better in Thailand | | Primary residence exemption | Yes (full exemption) | N/A | Comparable | | Non-resident rate | 33.33% (no allowance) | 0% | Thailand wins |
How are inheritance and succession handled for French owners of Thai property?
| Scenario | France | Thailand | |----------|--------|----------| | French resident dies owning Thai condo | French inheritance tax applies (up to 60%) | 0% Thai tax | | Thai resident dies owning Thai condo | 0% French tax (if non-resident at death) | 0% Thai tax | | French non-resident dies owning Thai condo | French inheritance tax may apply (limited scope) | 0% Thai tax |
The Hidden French Tax Risk
Even though Thailand has zero inheritance tax, French inheritance tax can still apply to Thai property if the deceased was a French resident. Key exemptions:
- Spouse: 100,000 EUR allowance, then 5–45% on the excess
- Children: 100,000 EUR each, then 5–45%
- Non-relatives: 1,594 EUR allowance, then 60%
Strategy: French residents with significant Thai property should consider:
- Holding the property through a Thai company (may limit French inheritance tax exposure)
- French notarial will addressing the Thai property
- Life insurance (assurance-vie) as a non-probate vehicle
Which professionals do French owners of Thai property need?
| Professional | Role | |-------------|------| | French tax lawyer (Paris or Bangkok) | Cross-border tax planning | | Thai lawyer (French-speaking) | Property acquisition, due diligence | | French notaire | French will, succession planning | | French accountant (expat specialist) | Annual tax filing (France + Thailand) |
REVR Warning: French tax law for foreign property is complex and changes frequently. The information above is a general guide — always consult qualified tax and legal professionals before making a purchase.

Does France Give a Tax Credit, or an Exemption, for Thai Rental Income?
The section above describes a tax credit. That is not what the France–Thailand convention does with property income. Under Article 6 of the convention of 27 December 1974, income from immovable property is taxable in the state where the property is situated, so the Thai rent is taxed in Thailand. Article 23 then relieves double taxation in France by the exemption method for that income, not by a credit. France does not tax the Thai rent and does not credit the Thai tax against French tax; it leaves the income to Thailand, while still counting it to set the effective rate applied to the taxpayer's other French income. The income-band table above, which nets the two systems against each other, therefore does not describe the mechanism.
Do French Social Charges Apply to Thai Rental Income?
Yes, and this is the most commonly missed point in cross-border planning. A French tax resident is liable to prélèvements sociaux on worldwide property income, and specifically on foreign property income that is exempt from French income tax under a treaty. The rate on revenus fonciers in 2026 is 17.2%: CSG at 9.2%, CRDS at 0.5% and the prélèvement de solidarité at 7.5%. The LFSS for 2026 raised CSG to 10.6% for most capital income, taking those to 18.6%, but Article L.136-8 IV of the Code de la sécurité sociale expressly keeps revenus fonciers at 9.2%, so property income stays at 17.2%. Of that, 6.8 points of CSG are deductible from taxable income the following year where the income is taxed at the progressive scale.
The only carve-out is social-security affiliation, not health insurance: a French resident affiliated to the compulsory social-security scheme of an EEA state or Switzerland pays only the 7.5% solidarity levy. Holding a private policy is not that. Foreign property income is declared on form 2047 and carried to the 2042 and 2044 returns.
How Are Gains on Thai Property Taxed for a French Resident?
The table above assigns 19% plus 17.2% to France. That is not what the treaty does. Article 13 gives the state where the property is situated the right to tax the gain, so Thailand taxes it, and Article 23 exempts the gain in France. On the Thai side an individual seller pays no personal income tax on the gain, but Specific Business Tax at 3.3% of the higher of price and appraised value applies where the property has been held for less than five years, and stamp duty of 0.5% applies instead where it has not. The practical Thai exit cost is therefore not zero.
Does the French Property Wealth Tax Reach Thai Property?
Yes, for a French tax resident. IFI applies once worldwide net real estate exceeds €1,300,000 on 1 January of the tax year, and Thai property held directly sits inside that base. A non-resident of France, by contrast, is within IFI only for French property. The treaty does not remove IFI; it prevents double taxation of income. A French resident holding a Thai villa above the threshold should treat the French wealth tax as live.
One caution on the Thai company idea floated above. Land held by a Thai company on behalf of a foreigner through nominee shareholders is the structure Thai authorities police most actively, and since 1 January 2026 DBD Order 2/2568 requires the Thai shareholders of a foreign-involved company to evidence the source of their capital. It is not a tax-planning step to take casually, and it is not a substitute for advice.
