Introduction: foreign prop firms and French residents
Prop firm trading has become a popular way to access financial markets without committing personal capital. However, a reality quickly imposes itself on every French trader: most prop firms are based abroad.
Whether you trade with Phidias Propfirm (Europe-based), Topstep or Apex (USA), FTMO (Prague) or other international players, a question systematically arises: how to declare this income in France and what are my tax obligations?
The taxation of foreign prop firms is a topic often poorly understood by traders. Between the legal nature of income, declaration obligations for foreign accounts, currency conversion and international tax treaties, the pitfalls are numerous.
This guide aims to give you a clear and synthetic vision of your obligations. It does not replace the advice of a professional, but it will allow you to ask the right questions and avoid the most common mistakes.
Important reminder: This article is a general informational guide. It does not constitute personalized tax advice. As each situation is unique, we strongly recommend consulting a chartered accountant or tax lawyer for your particular case.

Where are the main prop firms based?
Before addressing taxation, it's essential to know where the prop firms you work with are domiciled. This information largely determines your declaration obligations and applicable tax treaties.

The location of the prop firm has a direct impact on several aspects: forms to fill out, applicable tax treaties, possible withholding tax, and obligations to declare accounts abroad.
By choosing a European-based prop firm like Phidias Propfirm, you considerably simplify your tax obligations. No W-8BEN form, no complexity related to extra-European treaties. Discover it with code LUCAS for -80%.
The principle of tax residency
The fundamental concept to understand is that of tax residency. In French tax law, this is the criterion that determines in which country you are liable for tax on all your income.
Who is a French tax resident?
According to article 4 B of the French General Tax Code, you are considered a French tax resident if you meet at least one of the following criteria:
- Family home in France: your spouse and/or children live in France, even if you work abroad.
- Main stay in France: you spend more than 183 days per year on French territory.
- Main professional activity in France: your main economic activity is exercised in France.
- Center of economic interests in France: your main investments, business headquarters or the place where you manage your assets is in France.
The worldwide income rule
If you are a French tax resident, you are subject to the obligation to declare in France all your worldwide income, regardless of geographical source. This means that:
- Income from an American prop firm (Topstep, Apex) must be declared in France.
- Income from a Czech prop firm (FTMO) must be declared in France.
- Income from a UAE prop firm must be declared in France.
- Income from a European prop firm (Phidias) must be declared in France.
Warning: The fact that the prop firm is based in a country without income tax (like the UAE) in no way exempts you from declaring this income in France if you are a French tax resident. France taxes its residents on their worldwide income, independently of the source country's taxation.
There are situations where a trader can have dual tax residency. In this case, bilateral tax treaties between France and the other country contain tie-breaker rules to determine a single country of residence.
Legal nature of income: BNC, not capital gains
One of the most frequent confusions among prop firm traders concerns the tax qualification of their income. Many wrongly think it's capital gains subject to PFU (Prélèvement Forfaitaire Unique — flat tax of 30%). This is generally not the case.
Why BNC and not capital gains?
Income from prop firm trading is generally classified as BNC (Bénéfices Non Commerciaux — Non-Commercial Profits). Here's why:
- You don't trade with your own capital. The capital belongs to the prop firm. You therefore don't realize capital gains on your personal assets.
- You provide an intellectual service. The prop firm compensates you for your trading skill, via a profit-sharing mechanism (profit split).
- It's a service provision. Legally, the relationship between the trader and the prop firm is akin to a service provision compensated by a percentage of the gains generated.
Tax implications of the BNC regime
| Criterion | BNC (Prop Firm) | Capital gains (PFU) |
|---|---|---|
| Tax rate | Progressive IR scale + social contributions | Flat tax 30% |
| Capital used | Prop firm capital | Personal capital |
| Micro-BNC allowance | 34% (if receipts < 77,700 EUR) | Not applicable |
| Declaration | 2042-C PRO | 2042 / 2074 |
| Social contributions | URSSAF (if regular activity) | Social levies 17.2% |
Micro-BNC or controlled declaration?
If your prop firm income does not exceed 77,700 EUR per year (2026 threshold), you can opt for the micro-BNC regime. In this case, a 34% flat-rate allowance is applied to your receipts, and you are only taxed on the remaining 66%.
Beyond this threshold, or if you have significant deductible expenses, the controlled declaration regime may be more advantageous. It allows you to deduct your actual expenses (platform subscriptions, equipment, training, etc.).
Is auto-entrepreneur status suitable? Yes, it's a popular option for prop firm traders. Check our complete guide on auto-entrepreneur status and prop firm to understand the advantages and limitations of this regime.
Declaration of foreign accounts: form 3916
This is the least known obligation for prop firm traders, yet one of the most important. If you hold an account with a foreign prop firm, you are potentially concerned by the obligation to declare financial accounts abroad.
What is form 3916 / 3916-bis?
Article 1649 A of the French General Tax Code requires French tax residents to declare financial accounts opened, held, used or closed abroad during the year. This declaration is made via form 3916-bis, an annex to the income tax return.
Are prop firm accounts concerned?
The question is debated and depends on the qualification of the account. Here are the elements to consider:
- If the prop firm opens an account in your name on which funds transit, this account can be classified as a financial account abroad. Declaration is then probably mandatory.
- If you use a foreign payment intermediary (Rise, Wise, PayPal type) to receive your payouts, these accounts must also be declared.
- If the prop firm pays directly to your French bank account without an intermediary account in your name, the obligation is less obvious. Nevertheless, as a precaution, declaration is recommended.
How to fill form 3916-bis?
-
Identify all your accounts abroad List all accounts opened with foreign prop firms, payment intermediaries (Rise, Wise, Deel, PayPal) and trading platforms.
-
Gather necessary information For each account: organization name, address, account number, opening date, and if applicable closing date.
-
Fill form 3916-bis Accessible during your online declaration on impots.gouv.fr. Check box 8UU on your 2042 declaration to indicate you hold accounts abroad.
-
Attach form to your declaration Form 3916-bis is an annex to your income tax return. Submit it at the same time as your annual return.
Sanctions in case of non-declaration
The sanctions are heavy:
- 1,500 EUR fine per undeclared account if the account is located in a State having concluded an assistance treaty with France.
- 10,000 EUR fine per undeclared account if the account is located in a State that has not concluded such a treaty (non-cooperative State).
- Rights increase: in case of correction, undeclared income related to these accounts can be increased by 80%.
- Income presumption: sums transiting on an undeclared account can be presumed to constitute taxable income, unless proven otherwise.
Practical advice: In doubt, declare. It's always better to declare an account as a precaution than to expose yourself to a 1,500 EUR fine or more. The tax administration is much more lenient with a good-faith taxpayer who over-declared than with one who omitted to declare.
Income in foreign currencies: USD/EUR conversion
Most prop firms pay their traders in US dollars (USD). However, your French tax declaration must be established in euros. The question of the applicable exchange rate is therefore crucial.
Which exchange rate to use?
Several approaches are accepted by the tax administration:
- Exchange rate on the day of funds receipt: this is the most commonly used rate. You convert each payout at the EUR/USD exchange rate published by the ECB on the day the funds arrive in your bank account.
- Annual average exchange rate: to simplify, some accountants use the year's average exchange rate published by the ECB. This approach is simpler but may be less accurate.
- Rate applied by your bank: if your bank performs the conversion automatically, the euro amount credited to your account can serve as a basis.
Practical example
Imagine you receive a 5,000 USD payout on March 15, 2026:
| Method | EUR/USD rate | Amount in EUR |
|---|---|---|
| ECB rate of the day | 1 EUR = 1.08 USD | 4,629.63 EUR |
| Annual average rate | 1 EUR = 1.10 USD | 4,545.45 EUR |
| Rate applied by bank | 1 EUR = 1.09 USD (fees included) | 4,587.16 EUR |
The gap between methods may seem small on a single payout, but it becomes significant over an entire year with multiple payouts.
Best practice: Whatever method you choose, remain consistent throughout the year and keep supporting documents (bank statements, exchange rate screenshots, prop firm payment confirmations). In case of audit, consistency and traceability are your best assets.
Foreign exchange gain or loss
If you receive funds in USD and keep them before converting them to EUR, the exchange rate variation can generate a foreign exchange gain or loss. This gain or loss is not prop firm income per se, but it can have additional tax implications. Consult a tax specialist if you are in this situation.
International tax treaties
Bilateral tax treaties aim to avoid double taxation: being taxed twice on the same income in two different countries. Here is an overview of the most relevant treaties for prop firm traders.
General principle: tax credit
When income is taxed at source in a foreign country (withholding tax), the tax treaty generally provides for a tax credit mechanism in France. This credit reduces French tax by the amount of tax paid abroad, within the limit of the corresponding French tax.
1994 (amended) Franco-American tax treaty. Independent service income is generally taxable in the country of residence (France). No withholding tax if W-8BEN form is correctly filled.
Action: Fill out form W-8BEN with the prop firm to avoid the 30% American withholding tax.
Favorable treatyFranco-British tax treaty. Independent activity profits are taxable in the State of residence (France) unless the trader has a permanent establishment in the UK. Generally no withholding tax on service provisions.
Favorable treatyTax treaty signed in 1989. The UAE does not tax personal income. However, as a French resident, you remain taxed in France on this income. No tax credit since no tax paid in the UAE.
Neutral — no tax creditSome prop firms are registered in Cyprus. Tax treaty with France exists. Independent service income is taxable in France. Note Cyprus's perception as an advantageous tax jurisdiction: tax administration vigilance.
Vigilance requiredFTMO is based in Prague. Applicable Franco-Czech tax treaty. As an EU member, information exchanges are automatic. Independent service income is taxable in France. Relatively simple situation.
Favorable treaty — EUFor EU-based prop firms (like Phidias), the situation is the simplest. Automatic information exchanges, no specific W-8BEN type forms, and no complexity related to extra-European treaties.
Simplest situationPractical case: American withholding tax
American prop firms (Topstep, Apex) are subject to American tax law. Without the W-8BEN form, they are required to withhold 30% withholding tax on payments made to non-American residents.
The W-8BEN form (Certificate of Foreign Status of Beneficial Owner) allows to reduce or eliminate this withholding by invoking the Franco-American tax treaty. If the prop firm requests it, fill it out carefully. It's a standard document and most US prop firms offer it at registration.
Advantage of a European prop firm: By choosing an EU-based prop firm like Phidias Propfirm, you completely avoid the complexity of W-8BEN and extra-European tax treaties. It's a real asset to simplify your tax situation. Compare options on our 2026 prop firm comparison.
Crypto and prop firm: tax implications
Some prop firms offer cryptocurrency payouts (Bitcoin, USDT, USDC). If this is your case, you face an additional layer of tax complexity.
Potential double taxation regime
When you receive a payout in crypto, two tax events can occur:
- Payout receipt (BNC): The prop firm income is a BNC, regardless of payment method. It must be valued in euros at the cryptocurrency rate at the time of receipt.
- Conversion of crypto to euros (capital gain): If you then convert the crypto to euros and the rate has evolved between receipt and conversion, you realize a capital gain (or loss) on digital assets subject to 30% PFU.
Beware of the double taxation trap: You pay social contributions and IR on the BNC at the time of receipt. Then, if the crypto rate increases, you pay 30% again on the capital gain upon conversion to euros. This is an unfavorable situation to anticipate. If possible, convert your crypto payouts to euros quickly to minimize this risk.
Additional declaration obligations
If you hold cryptocurrencies, additional obligations apply:
- Declaration of foreign crypto-asset accounts: If you use a foreign crypto platform (Binance, Kraken, etc.), these accounts must be declared on form 3916-bis.
- Declaration of digital asset capital gains: Any digital asset disposal (crypto to fiat) must be declared on form 2086.
- Tracking of acquisition price: You must keep track of the crypto rate at the time of payout receipt to correctly calculate your capital gain upon conversion.
If the tax complexity related to cryptos worries you, favor prop firms that offer classic bank transfers. Phidias Propfirm makes its payouts via Rise in direct bank transfer, which considerably simplifies your tax situation.
Warning: consult a professional
This guide does not replace professional tax advice
International taxation is a complex and constantly evolving field. The information presented in this article is provided for informational and educational purposes. It does not constitute personalized tax, legal or accounting advice.
We strongly recommend consulting a chartered accountant or tax lawyer specialized in international taxation in the following cases:
- Your prop firm income exceeds 20,000 EUR per year.
- You trade with multiple prop firms based in different countries.
- You receive cryptocurrency payouts.
- You have doubts about your tax residency (expatriation, dual residency).
- You are considering creating a legal structure (micro-entreprise, SASU, EURL) for your trading activity.
- You omitted to declare accounts or income in previous years (regularization possible).
The cost of consulting a professional (between 100 and 300 EUR for an initial appointment) is insignificant compared to the risks of tax adjustment (fines, surcharges, late interest) in case of error or omission.

Frequently Asked Questions
Yes, as a French tax resident, you must declare all your worldwide income, including income from prop firms based abroad (USA, UK, UAE, etc.). This income is generally declared as BNC (Non-Commercial Profits) on your annual income tax return via form 2042-C PRO.
Prop firm income is generally classified as BNC (Non-Commercial Profits), as it is an intellectual service compensated by profit sharing. You don't trade with your own capital, so it's not capital gains subject to the 30% PFU (flat tax). The micro-BNC regime with 34% allowance can apply if your receipts are below 77,700 EUR.
Yes, if your trading account with a foreign prop firm can be classified as a financial account opened abroad, you must declare it via form 3916-bis. Failure to do so can result in a 1,500 EUR fine per undeclared account, or even 10,000 EUR if the account is located in a non-cooperative State. In doubt, declare as a precaution.
For tax declaration, you must convert your USD income to euros. The applicable exchange rate is generally the ECB rate on the day of actual receipt of funds in your bank account. You can also use the annual average rate to simplify. Keep proof of conversion (bank statements, payment screenshots) to justify the declared amounts.
Yes, payouts received in cryptocurrency are taxable. The prop firm income remains a BNC valued at the crypto rate at the time of receipt. Moreover, if you then convert this crypto to euros with a capital gain, it is subject to the digital assets regime (30% flat tax). There is therefore potentially double taxation to anticipate. Favor payouts by bank transfer to simplify.
