Occasional vs Habitual Crypto Trader in France

Of all the questions in French crypto tax, this one has the highest stakes and the least precise answer, which is why it gets its own article. Are you an occasional investor, taxed at 31.4% PFU on your disposals, or a habitual/professional trader taxed under BNC? France did not set a number to draw the line; it is a bundle-of-facts judgement the DGFiP makes case by case, usually after an audit and often for past years. This piece covers the criteria, the risk zone, and what an audit looks like. What the two regimes actually tax is set out in BNC vs PFU; the pillar is the France crypto tax guide.

Key points

• An occasional investor's disposals are taxed at 31.4% PFU (article 150 VH bis).
• A habitual/professional trader is taxed under the BNC regime (which replaced BIC via the Loi de Finances 2022, effective 2023).
• There is no numeric threshold; it is a bundle-of-facts test (frequency, tools, time, capital, income share, organisation).
• Reclassification usually follows an audit, often with back years reassessed.
• Genuine buy-and-hold with occasional sales is firmly occasional; bots, leverage, and daily structured trading are the risk zone.

Two statuses, two regimes

The occasional regime is the default for retail. The professional regime is heavier and is where reclassification risk lives. The two are mutually exclusive for the disposal side: you are taxed on trading either as occasional (PFU) or as professional (BNC) — not both — though reward income (staking etc.) is BNC regardless (see BNC vs PFU).

There is no number

The most important and most uncomfortable fact: France did not set a threshold. The Loi de Finances 2022 (effective 1 January 2023) clarified the criteria but deliberately produced no numeric line — not a number of trades, not a volume, not a value. The DGFiP and the courts examine the facts case by case. Documented criteria they weigh:

• Time between purchase and resale (short cycles → professional indicator)
• Number of assets sold and frequency of operations
• Conditions of acquisition and the overall pattern
• Tools used (manual vs bots, leverage, sophisticated derivatives)
• Time devoted to the activity
• Whether it is a main income source
• Business-like organisation

No single factor is decisive. It is the combination, sustained over time, that produces professional status. This is the same shape as the UK "badges of trade" or the Belgian/Irish private-vs-professional tests — but France's version is explicitly numberless.

The risk zone

The middle row is where most disputes happen. The defensible move there is contemporaneous documentation of the private-management character (holding rationale, absence of automation, secondary nature) — the burden of demonstrating occasional status effectively falls on the taxpayer once professional indicators appear.

Why reclassification is expensive

Reclassification rarely happens prospectively and politely. It typically happens after an audit, and the DGFiP can reassess back years within the reassessment period. So the cost is not "this year at BNC instead of PFU" — it can be several years reassessed, plus interest and surcharges. That is why the genuine risk-zone trader should resolve status before the audit, with an expert-comptable, rather than discover it during one.

DAC8 sharpens this from 2026: CASP-reported data gives the DGFiP a clear, multi-year picture of trading frequency and volume — exactly the pattern that triggers the professional examination (see DAC8 impact on individuals).

Practical guidance

1. Honestly profile your activity against the criteria — frequency, tools, time, capital share, income share, organisation.
2. If clearly occasional: keep it that way; light documentation of the buy-and-hold posture is enough.
3. If in the risk zone: get an expert-comptable now; document the private-management character contemporaneously.
4. If clearly professional: file under BNC (micro-BNC 34% or déclaration contrôlée) rather than wait to be reclassified with back-years.
5. Assume DAC8 makes the pattern visible — the multi-year frequency picture is now reported.

Using a tool for the evidence, not the verdict

No tool can tell you whether you are a professional; that is a legal judgement on a bundle of facts. What a tool can do is assemble the evidence base an adviser argues from. Look for one that:

• computes the occasional-investor PFU output under the 150 VH bis method, as the working assumption;
• surfaces the activity metrics the assessment turns on — operation frequency, number of assets, holding periods, capital deployed;
• preserves a dated, exportable history you can show an inspector, rather than a single summary figure;
• stops short of asserting a status, leaving that conclusion to you and your adviser.

Waltio is French-specialised and Koinly supports the French regime; both produce the PFU output and useful activity metrics. Use them for the evidence, not the conclusion.

How Wag3s fits in

Wag3s Folio surfaces the activity metrics the occasional/habitual assessment turns on — frequency, holding periods, operation counts — and produces the dated, documented history needed to argue the private-management posture, reconciled against DAC8-reported activity. The status itself is a legal judgement; Folio is built to hand an expert-comptable the evidence to make and defend it, not to reach it on your behalf.

What happens during a DGFiP audit on the professional question

For investors in the risk zone, understanding the audit process is as important as understanding the criteria. The DGFiP does not typically send a letter announcing "we think you are a professional trader." The reclassification usually emerges during a contrôle fiscal (tax audit), which can be triggered by a discrepancy between reported income and lifestyle, by CASP-reported activity under DAC8, or by a routine audit cycle.

During the audit, the inspector will request access to exchange account statements, transaction logs, and bank account records showing crypto-related proceeds. They will build a transaction frequency table. If the pattern is consistent with professional activity — daily or near-daily operations, short holding periods, significant capital deployed, bot or API-driven trading — the inspector will raise a proposition de rectification (notice of adjustment) reclassifying the activity as BNC.

The taxpayer then has 30 days to respond. The response window is where the documentation of occasional/private-management character matters. If the investor can demonstrate that high activity was due to specific, temporally bounded circumstances (a volatile market period, a one-time rebalancing event), that holding periods were in fact longer than raw transaction counts suggest, or that the activity does not represent a professional setup (no bots, no leverage, no business organisation), the argument can succeed.

If no adequate response is made, or if the inspector is not persuaded, the reassessment proceeds. The DGFiP can reassess back three years (standard) or six years (where there is evidence of intentional omission). For a high-frequency trader reassessed over three years at BNC rates, the difference from PFU can be substantial — progressive income tax is not capped at 31.4%; at higher income levels the marginal rate is 45% plus social charges.

The practical implication: maintain contemporaneous records of the rationale for trades (investment thesis notes, even brief ones), the absence of automation, and the secondary nature of the activity relative to total income. These records are evidence in an audit; there is no substitute for them after the fact.
