Referral Bonuses in France?

Article 79 of the French General Tax Code (CGI) sets the general principle: all income that is not expressly exempt is, in theory, taxable. The question is therefore: is a referral bonus "income" within the meaning of the CGI? The answer hinges on a fundamental distinction in French tax law — that between a commercial discount (remise commerciale) and business income (revenu d'activité).

The DGFiP has not published a specific administrative ruling on referral bonuses paid by online banks, energy providers, or cashback apps. The tax authority therefore applies general principles, and French tax case law clearly leans towards classifying occasional referral bonuses linked to a subscription as a commercial discount — not taxable income.

This is not unique to France: most European tax systems make the same distinction between a price reduction on a service and income derived from an activity. The key word here is "occasional" — the moment referral becomes organised and systematic, the legal analysis changes.

This is the most common scenario — and the most favourable for individuals. When you open a Fortuneo or BoursoBank account via a referral link and receive a welcome bonus of €80 to €150, French tax experts treat this sum as a commercial discount.

The reasoning: you have performed a consumption act (opening a bank account, subscribing to a financial service). The bank offers you an advantage in return to attract and retain you — exactly like a discount voucher offered on a first online purchase. This discount reduces your cost of entry into the service, but does not remunerate a service you have provided.

The same logic applies to cashback received via apps like Joko: cashback is a retrospective discount on purchases you have made. It is no more taxable than a supermarket loyalty programme. And for energy referral bonuses (Octopus Energy, La Bellenergie), the same rule applies: a bonus paid on activating an energy contract is a commercial advantage linked to a subscription.

In practical terms: if you received €300 in bank referral bonuses and €80 in cashback during 2025, you have no boxes to fill in on your 2026 income tax return for these amounts.

That said, we recommend keeping all your records (bonus payment confirmations, bank statements, confirmation emails) for 3 years — the French tax limitation period. In the event of a query, you will be able to justify the nature of these payments.

Crypto platforms such as Binance or Coinbase often pay their referral bonuses not in euros but in cryptocurrencies (BTC, ETH, or their own tokens). This case is fiscally different — and considerably more complex.

Article 150 VH bis of the CGI, which governs the taxation of digital assets in France, imposes the 30% flat tax (PFU — prélèvement forfaitaire unique) on capital gains realised when digital assets are sold. The regime applies from the moment total disposals exceed €305 in the year.

In practice, this means your crypto bonuses are not taxed when received, but when sold. If you hold your tokens indefinitely, no tax is due. It is only at the point of sale that the flat tax applies.

By contrast, if a platform pays your referral bonus directly in euros (SEPA bank transfer), the commercial discount logic applies again — a cash payment is not a capital gain on a digital asset disposal.

For active users across multiple crypto platforms accumulating significant token bonuses, a dedicated crypto tax tracking tool (Waltio, Koinly, CoinTracking) is strongly recommended. These tools automatically calculate your gains and generate the annexe 2086 required for your French tax return.

There is a threshold that the most active referrers in France need to be aware of: the line between occasional referral and an organised, habitual activity. The distinction is set by Article 92 of the CGI, which defines BNC (non-commercial profits) as covering "all benefits from liberal professions [...] and all lucrative occupations and sources of profits not falling under another category of income."

In practice: if you run a blog, an Instagram account, or a dedicated website for referral codes — systematically recruiting new customers and generating regular, significant income from it — the DGFiP could reclassify your activity as BNC. The criteria typically considered are:

• ! Habitual nature: you perform referral operations repeatedly and in an organised manner throughout the year
• ! Profit motive: the primary objective is to generate profit (not simply to use a service you genuinely appreciate)
• ! Significant amounts: several thousand euros in referral bonuses per year generated through an organised activity

As a practical guideline, if you accumulate more than €1,500 to €2,000 annually in referral bonuses across all categories from an organised activity (website, social media, email campaigns), consulting an accountant is strongly recommended. The micro-BNC regime allows you to declare these revenues with a flat-rate deduction of 34%.

In contrast, referring 3 or 4 close friends and collecting a few hundred euros a year does not constitute a professional activity in the tax sense. This is the normal use of a loyalty programme — no different from someone who always buys their fuel at a petrol station offering loyalty points.

For the vast majority of people who use referral bonuses occasionally to save money in France, the tax risk is practically non-existent. Opening two or three bank accounts via referral codes, switching energy provider, and using a cashback app does not constitute a professional activity.
