Foreign Income: How to File Without Errors in 2026 (2035 Tax Return)

Sophie, an osteopath in Lyon, discovered in 2023 that she needed to report her virtual sessions with Belgian patients. The problem? She filled out her 2035 tax return as if these were French income, without checking the boxes for international revenue. The result? A notice from URSSAF in 2024 for unpaid social contributions on those amounts, plus a 10% penalty. Her mistake? Assuming that income received in euros via Stripe was automatically "French."

With the rise of teleconsultations and online training, more and more self-employed wellness practitioners (naturopaths, psychologists, physiotherapists, etc.) are earning income abroad. In 2024, according to a study by the Fédération Française des Praticiens de Santé (FFPS), 18% of wellness practitioners billed at least one client outside France—up from just 5% in 2020. Yet fewer than 30% of them report this income correctly, according to DGFiP data.

Why? Because the 2035 tax return isn’t designed for cross-border income. The dedicated fields are hard to find, tax rules vary by country, and social contributions become a headache. This article explains how to report your international income on the 2026 2035 tax return, avoid double taxation, and optimize your tax situation—without getting lost in jargon.

1. Which Income Is Affected (and Which Isn’t)?

Not all foreign income is reported the same way. Here’s a simple breakdown to clarify.

1.1 Income to Report in France (Even If Earned Abroad)

The basic rule: If you’re a French tax resident, you must report all worldwide income, including earnings from abroad. This includes:

• Teleconsultations: Virtual sessions with patients in Switzerland, Belgium, Canada, etc. (even if paid in euros via Stripe or PayPal).
• Online workshops: Live or recorded training sessions or conferences billed to foreign participants.
• Digital product sales: E-books, coaching programs, or subscription-based content (e.g., an online sophrology platform).
• Royalties: Copyright earnings from books or audio recordings sold internationally.

Real-world example: Thomas, a hypnotherapist in Bordeaux, hosts monthly online workshops for Canadian clients. In 2025, he earned €4,200 via Zoom and Stripe. This income must be reported in France, even though it came from abroad.

1.2 Income Not to Report in France (Under Certain Conditions)

Some income is exempt from French taxation if you can prove you’ve already paid taxes in the source country. This applies to:

• Income earned in a country with a tax treaty with France (e.g., Switzerland, Belgium, Canada). These treaties prevent double taxation. Note: You still must report this income in France but can claim a tax credit.
• Occasional income under €3,050/year (2026 threshold for micro-entrepreneurs). Above this, it becomes taxable in France.

Common pitfall: Income processed through platforms like Doctolib or Médoucine is often treated as "French" by default, even if the client is abroad. Always verify your client’s country of residence.

1.3 The Special Case of Social Contributions

Social contributions (URSSAF, CARPIMKO, etc.) don’t follow the same rules as income tax. Even if you’re exempt from French taxes due to a tax treaty, you may still owe social contributions in France.

• If you’re self-employed: You contribute to URSSAF or your professional fund (e.g., CARPIMKO for physiotherapists) on all worldwide income, unless you prove you’re already contributing in another EU/EEA country (via a Form S1).
• If you’re a micro-entrepreneur: You contribute on both French and foreign income, unless you can justify affiliation with a foreign social security system.

Key stat: In 2024, 62% of URSSAF audits for wellness practitioners involved unreported foreign income (source: URSSAF).

2. Where to Report This Income on the 2035 Tax Return

The 2035 form doesn’t have a dedicated "international income" field. Here’s where to report it based on your situation.

2.1 For Non-Commercial Profits (BNC)

If you’re on the controlled declaration regime (actual expenses), you must:

1. Report the total amount in Box 5HQ ("Taxable foreign income").
2. Detail income by country in Annex 2047 (required if income exceeds €1,500 per country).
3. Attach an explanatory note if income comes from multiple sources (e.g., teleconsultations + workshops).

Example: Sophie (osteopath) earned €3,200 from Swiss teleconsultations and €1,800 from Belgian workshops. She reports €5,000 in Box 5HQ and fills out Annex 2047 with amounts per country.

2.2 For Micro-Entrepreneurs

If you’re on the micro-BNC regime, report foreign income in:

• Box 5HN ("Non-commercial income") on the 2042 C PRO supplementary return.
• Annex 2047 if foreign income exceeds €1,500 (even for micro-entrepreneurs).

Important: Micro-entrepreneurs must also report this income in their quarterly URSSAF declaration ("Other income" box).

2.3 Specific Fields to Avoid Double Taxation

If you’ve already paid taxes abroad, you can claim a tax credit in France. To do this:

1. Fill in Box 8TK ("Tax credit equal to foreign tax paid") on Form 2042.
2. Attach a tax certificate from the source country (e.g., "Certificate of Tax Residence" for Switzerland).
3. Keep payment proofs (bank statements, invoices) for 6 years.

Case study: Marc, a psychologist in Lille, paid €800 in Belgian taxes on his teleconsultation income. He reports this amount in Box 8TK and attaches the Belgian tax certificate. Result: He won’t pay French taxes on this income.

3. Key Tax Treaties to Know (By Country)

France has tax treaties with over 100 countries to avoid double taxation. Here are the rules for the most common countries among wellness practitioners.

3.1 France-Switzerland: The "Occasional Income" Trap

• Rule: Income earned in Switzerland is taxable there if you work there occasionally (fewer than 90 days/year). Beyond that, it’s taxable in France.
• Exception: Income from teleconsultations (without physical presence in Switzerland) is taxable in France.
• Social contributions: You contribute in France unless you prove affiliation with Swiss AVS.

Source: France-Switzerland Tax Treaty (Article 14), updated 2023.

3.2 France-Belgium: The 183-Day Rule

• Rule: Belgian income is taxable in Belgium if you spend more than 183 days/year there. Otherwise, it’s taxable in France.
• Remote work: Teleconsultation income is always taxable in France, even if the client is Belgian.
• VAT: If you bill over €35,000/year to Belgian clients, you must register for Belgian VAT (OSS scheme).

Key stat: In 2024, 12% of French physiotherapists billed Belgian clients (source: Ordre des Masseurs-Kinésithérapeutes).

3.3 France-Canada: Online Workshops

• Rule: Canadian income is taxable in Canada if you have a "permanent establishment" there (e.g., an office, even temporary). Otherwise, it’s taxable in France.
• Online workshops: Income from live sessions for Canadian participants is taxable in France.
• Social contributions: You contribute in France unless affiliated with the Canadian RRQ system.

3.4 How to Find Your Country’s Tax Treaty

1. Visit impots.gouv.fr > "International" > "Tax Treaties."
2. Select the relevant country.
3. Look for articles on non-commercial profits (BNC) or independent income.

Tip: Use the DGFiP simulator (link here) to check your situation.

4. Common Pitfalls (and How to Avoid Them)

Reporting international income is like navigating a minefield—one mistake can be costly. Here are the most common traps and how to sidestep them.

4.1 Forgetting VAT on Digital Services

Since 2021, digital services (teleconsultations, online workshops, e-books) are subject to the client’s country VAT, even if you’re VAT-exempt in France.

• EU clients: Apply their country’s VAT (e.g., 21% for Belgium, 19% for Germany) and report it via the OSS scheme.
• Non-EU clients: No VAT, but document this in your accounting.

Example: Clara, a sophrologist, sold a €50 e-book to a Belgian client. She must charge €50 + €10.50 Belgian VAT (21%) and report it via OSS.

Tools to simplify:

• PratiConnect: Automatically generates invoices with the correct VAT for the client’s country.
• Quaderno or Taxamo: Calculate VAT based on the client’s location.

4.2 Misreporting Social Contributions

Many practitioners assume foreign income is exempt from French social contributions. This is false.

• Self-employed: Contribute to URSSAF on all worldwide income, unless you prove affiliation with a foreign social security system (e.g., EU/EEA Form S1).
• Micro-entrepreneurs: Contribute on both French and foreign income, unless exempt.

Trap: Some countries (e.g., Switzerland) don’t consider teleconsultations as local activity. Result: You may owe contributions in both France and Switzerland without a credit.

Solution: Always check the source country’s rules with an international tax accountant (e.g., Expertis, Fiducial).

4.3 Failing to Keep Payment Proofs

During an audit, URSSAF or DGFiP may ask for proof of foreign income. Without documentation, it’s treated as unreported French income.

Documents to keep for 6 years:

• Bank statements (Stripe, PayPal, wire transfers).
• Invoices (with client’s country noted).
• Client tax residence proofs (if applicable).
• Foreign tax certificates (for tax credits).

Tools:

• PratiConnect: Automatically archives invoices and bank statements.
• Deel or Wise: Generate detailed records for international payments.

4.4 Confusing Tax Residency with Nationality

You can be a French tax resident even with a foreign nationality or spending time abroad. The rules:

• You’re a French tax resident if you spend >183 days/year in France.
• OR if your primary home/family is in France.
• OR if your main economic interests (primary income source) are in France.

Example: Laura, a naturopath, spends 6 months/year in Portugal. She assumes she’s not a French tax resident. Wrong: Her main practice is in Paris, and 80% of her income comes from French clients. She must report worldwide income in France.

FAQ

Can I Report Foreign Income as a Micro-Entrepreneur?

Yes, but with limits. As a micro-entrepreneur, report foreign income in Box 5HN of Form 2042 C PRO. Problem: You can’t deduct actual expenses (only a 34% flat deduction applies). If foreign income exceeds €10,000/year, switch to the controlled declaration regime (actual expenses) to optimize taxes.

How Do I Prove I Paid Taxes Abroad?

Provide a tax certificate from the source country proving you paid taxes on the income. Examples:

• Switzerland: "Certificate of Tax Residence" from the cantonal authority.
• Belgium: "Certificate of Tax Residence" from myminfin.be.
• Canada: "Notice of Assessment" from the CRA.

Attach this certificate to your 2035 return and report the tax paid in Box 8TK.

What If I Get an URSSAF Notice for Foreign Income?

1. Don’t panic: URSSAF notices for foreign income are common (62% of audits in 2024, per URSSAF).
2. Check the reason: URSSAF may claim you didn’t report the income or didn’t pay social contributions.
3. Respond with proof: Provide bank statements, invoices, and foreign tax certificates.
4. Request a payment plan: URSSAF often allows installments for large amounts.
5. Get help: An accountant can negotiate penalty reductions (up to 50% in some cases).

Do I Owe French VAT on Foreign Income?

No, if your clients are outside France. Here’s how it works:

• EU clients: Apply their country’s VAT (e.g., 21% for Belgium) and report via OSS.
• Non-EU clients: No VAT, but document this in your accounting.
• French clients: Apply French VAT (20% or 10%, depending on your service).

Exception: If you’re VAT-exempt (turnover < €36,800 in 2026 for BNC), you don’t charge VAT, even for French clients.

How Do I Report Cryptocurrency Income?

Cryptocurrency income (Bitcoin, Ethereum, etc.) is taxable in France like euro income. Here’s how to report it:

1. Convert to euros at the transaction date’s exchange rate (use CoinMarketCap or CoinGecko).
2. Report in Box 5HQ (BNC) or 5HN (micro-BNC).
3. Keep records: Screenshots of transactions, wallet statements (e.g., Ledger, Trezor).

Warning: If you hold crypto for over a year, it becomes a capital gain (taxed at 30% in 2026).
