France Crypto Tax for Non-Residents

The non-resident crypto question has two steps, and the order is the whole game: are you actually a non-resident, and then what does the treaty say. Most disputes are lost at step one, where people assume a non-residence they cannot substantiate, especially in the year they leave. This article focuses on that residence determination and the treaty logic that follows; it sits alongside the exit-tax analysis for those departing with latent gains, and the France crypto tax guide covers the resident baseline.

The non-resident question in brief

• The obligations bind residents: Form 2086 and 3916-bis in principle apply to French tax residents.
• The residence test (article 4 B CGI) turns on home or principal place of stay, main professional activity, or centre of economic interests in France.
• The treaty allocates the rest: capital gains on movable assets like crypto are usually taxed in the residence state, not the source state, but it is treaty-by-treaty.
• The departure-year trap is real: you are often still resident for part of the leaving year, and tie-breakers can extend it.
• DAC8/CARF still reach you for prior-resident years and French-linked legacy activity.

Step 1: are you actually a non-resident?

This is where the analysis lives or dies. Under article 4 B CGI, you are a French tax resident if any of these is true:

• Your home (foyer) or principal place of stay is in France;
• You carry on your main professional activity in France;
• France is the centre of your economic interests.

It is a facts test, not an election or a postcode. Holding crypto on a French PSAN, or having a French bank account, does not make you resident. But keeping your family home, your main work, or your economic centre in France does — even if you spend significant time abroad. Many "non-resident" crypto positions fail here: the person never cleanly ceased French residence under 4 B.

Step 2: what the treaty allocates

If (and only if) you are a genuine non-resident, France taxes you only on French-source income, and a bilateral tax treaty with your residence country allocates the taxing rights. For capital gains on movable property — the category crypto generally falls in — treaties following the OECD model typically allocate the taxing right to the residence state, not the source state.

Practical consequence: a genuine non-resident's crypto gains are usually taxable in their country of residence, not France. But this is treaty-by-treaty: the France–residence country treaty governs, and some treaties have specific provisions. There is no universal answer; the treaty text is the authority. A non-resident must read their treaty, not assume the OECD default.

The 3916-bis point for non-residents

The foreign-account declaration (Form 3916-bis) is, in principle, a resident obligation (see Cerfa 3916-bis). A genuine non-resident is generally outside it. But two cautions:

1. The obligation applied for every year you were resident — non-residence now does not erase prior-resident-year 3916-bis duties.
2. The departure year is usually a part-resident year — the obligation can still bite for that year.

The departure-year trap

The most common failure: treating the year of leaving as a clean non-resident year. It rarely is. You are typically a French tax resident for the part of the year before departure; treaty tie-breaker rules (permanent home, centre of vital interests, habitual abode, nationality) can keep you French-resident longer than you assume. Crypto gains realised while still resident remain French-taxable under the PFU/150 VH bis regime, and the exit-tax analysis applies to the structure. The residence-cessation date is a precise legal question — resolve it with counsel before acting on a non-resident assumption.

The treaty tie-breaker cascade and why property matters

Under the OECD-model framework, if a person meets the residence test in both France and their new country simultaneously, the treaty resolves the conflict through a prioritised sequence:

1. Permanent home: which state has a fixed, permanently available home? A French apartment the person retained, even if rarely visited, can qualify as a permanent home and anchor treaty residence in France at this first step.
2. Centre of vital interests: where are the personal and economic ties? This is more holistic — family, professional relationships, bank accounts, business interests.
3. Habitual abode: where does the person spend more time during the year?
4. Nationality: as a last resort.

The tie-breaker is applied in order: if step 1 gives a clear answer (one permanent home only), steps 2–4 are irrelevant. This is why the decision to retain or relinquish a French property in the departure year is not merely a practical matter — it is a treaty-residence determination. Keeping the apartment means the tie-breaker may resolve at step 1 in France's favour, keeping the person French-resident under the treaty for longer than they expected. This is the most frequently overlooked mechanism in departure-year crypto-tax planning.

DAC8/CARF do not respect your move

Information reporting operates independently of current residence. A person with a French residency history, French-linked accounts, or a transition year can still surface via DAC8/CARF data shared with the DGFiP (see DAC8 vs CARF). Becoming non-resident does not retroactively erase prior-resident-year obligations or stop reporting on legacy French-linked activity. The detection layer and the residence layer are separate.

Practical guidance

1. Test residence rigorously under article 4 B CGI — foyer, main activity, economic centre. Do not assume.
2. If genuinely non-resident, read your specific France–residence-country treaty — movable-asset gains usually go to the residence state, but verify.
3. Treat the departure year as part-resident until counsel confirms the cessation date; gains while resident stay French-taxable.
4. Settle prior-resident-year obligations (2086, 3916-bis) — non-residence does not erase them.
5. Expect DAC8/CARF to surface French-linked history regardless of current residence.
6. Address the property question explicitly — retaining a French permanent home can keep treaty residence in France at the first tie-breaker step.

Where a tool fits

Waltio and Koinly reconstruct the history needed for the resident-period and departure-year French filing and any treaty/CARF reconciliation. They do not determine residence or interpret a treaty; that is a French-tax-lawyer judgement. Use a tool for the figures and counsel for residence and treaty allocation.

Where Wag3s fits

Wag3s Folio reconstructs the multi-chain history across resident and transition years, the records a holder navigating a change of residence needs to file the resident period correctly and reconcile against DAC8/CARF-reported activity. The residence determination under article 4 B and the reading of a specific bilateral treaty are a French tax lawyer's; Wag3s produces the figures, it does not decide where you are resident.
