Cryptocurrency taxation is one of the most concrete reasons why some expats choose their next country of residence carefully. Between France’s 30% flat tax, conditional exemptions in Germany, zero taxation in the UAE, and the new reporting rules now in force across Europe, the subject is complex but decisive. This guide covers what actually applies in 2026 depending on your situation.
Tax residency: the primary determining factor
Why it drives everything
With cryptocurrencies, the rule seems simple: you are taxed where you are a tax resident, not where your exchange is located. Whether your account is on Binance in the Seychelles, Coinbase in the United States, or Kraken in Europe, it is your country of tax residence that determines the rate applicable to your capital gains.
Tax residency is determined by specific criteria: location of your main home, length of stay (often 183 days or more per year), location of your economic and professional interests. In France, these criteria are set out in article 4 B of the General Tax Code, and the Direction générale des Finances publiques recommends formalising the transfer with a non-residency notice.
What this means in practice
As long as you are a French tax resident, all your cryptocurrency disposals are subject to the French regime. Once you change your tax residency and sell after that change, it is the new country’s taxation that applies. The timing of your sales relative to your change of residency can represent tens of thousands of euros of difference on a significant portfolio.

French crypto taxation: what applies in 2026
The 30% flat tax
In France, capital gains realised on cryptocurrency disposals by individuals are subject to the single flat-rate levy (PFU) of 30%: 12.8% income tax + 17.2% social levies. This rate applies to the net gain (sale price minus weighted average acquisition price).
It is possible to opt for the progressive income tax scale if more advantageous, particularly for low-income households. But for most crypto holders with significant gains, the 30% flat tax is the applicable regime.
The detailed calculation and declaration rules are published on impots.gouv.fr.
What is taxable (and what is not)
Taxable in France: sales of crypto for euros or other fiat currencies, purchases of goods or services using crypto. Not taxable: crypto-to-crypto swaps (since the Pacte law, a BTC/ETH swap is not a taxable event), simple holding, transfers between your own wallets.
The rules have evolved and may continue to do so: always check the official French tax bulletin (BOFiP) for the most current guidance.
Exit tax and crypto: a nuanced point
The principle of exit tax
The French exit tax (article 167 bis of the General Tax Code) aims to tax unrealised gains when a taxpayer transfers their tax residency outside France. Its purpose is to prevent someone from leaving just before realising a gain in order to escape French taxation.
The exit tax applies to securities (shares, partnership interests, bonds, social rights) with a total value above 800,000 euros, or representing more than 50% of a company’s profits.
The status of cryptocurrencies under exit tax
This is where the subject becomes nuanced. Under current French law (Q3 2026), cryptocurrencies do not constitute securities within the meaning of the General Tax Code and therefore fall outside the scope of the traditional exit tax. A Bitcoin or Ethereum portfolio, however large, is not caught by article 167 bis.
However, if you hold tokens that resemble equity interests in a company (certain security tokens, tokenised fund units), the analysis may differ depending on their precise legal qualification.
This position may evolve: several parliamentary reports have raised the possibility of extending exit tax to digital assets. Consult a specialist tax adviser before any departure if you hold a significant portfolio. This is an area of law still under construction.
Timing: the most strategic variable
Sell before or after changing residency?
This is the central question for any expat holding crypto with unrealised gains. A concrete example: you have 500,000 euros of unrealised gains and plan to settle in Dubai.
- If you sell before leaving (still a French tax resident): 30% flat tax, meaning 150,000 euros in tax.
- If you sell after establishing residency in Dubai (UAE tax resident): 0% tax on crypto capital gains.
The difference is considerable. But the change of tax residency must be real, not simulated. You must have genuinely severed your tax domicile from France, established your home in the UAE, and be able to prove it (lease, residency visa, local bank statements, effective presence of over 183 days).
The 183-day rule is not always enough
Some taxpayers believe that spending 183 days outside France is sufficient to stop being taxable there. This is an oversimplification. The French tax authority can reassess residency if the centre of economic or family interests remains in France. Significant crypto portfolios are potential audit targets when a departure looks like a fictitious domiciliation.
Crypto-friendly countries in 2026: a comparison
Portugal
Portugal has undergone significant changes to its crypto taxation. Since 2023, capital gains on crypto held for less than one year are taxed at 28%. In contrast, cryptos held for more than 365 days remain exempt from capital gains tax for individuals. This regime makes Portugal very attractive for long-term holders.
The NHR (Non-Habitual Resident) status was reformed in 2024 and replaced by the IFICI regime, but crypto continues to benefit from favourable treatment for long-term holders. Find all the practical details in our guide on moving to Portugal.
United Arab Emirates (Dubai)
The UAE has no personal income tax, no capital gains tax. Crypto gains are therefore taxed at 0% for residents. It is one of the most sought-after destinations for crypto investors with substantial portfolios.
To establish residency, you need a residence visa (through employment, a free zone, an investor visa, or the Golden Visa). Our full guide: moving to Dubai.
Germany
Germany applies a long-established and well-known exemption rule: cryptocurrencies held for more than 12 months by individuals are completely exempt from capital gains tax upon sale. Below one year of holding, the gain is taxed at the taxpayer’s marginal income tax rate (up to 45% plus the solidarity surcharge).
This rule, arising from the classification of cryptos as “other assets” (private Veräußerungsgeschäfte) under German tax law, has been stable for several years. It represents one of the most favourable tax regimes in Europe for a patient long-term holder.
Switzerland
Switzerland is generally favourable for individual crypto holders. Capital gains on crypto are in principle exempt from income tax for individuals who do not engage in professional trading. However, crypto assets are subject to wealth tax (cantonal and federal). The cantons of Zug (Crypto Valley), Schwyz, and Nidwald are known for their advantageous wealth taxation.
The distinction between exempt private gains and taxable professional activity depends on several criteria: frequency of transactions, leverage used, proportion of total income. A prior cantonal tax ruling is recommended.
El Salvador
El Salvador was the first country to adopt Bitcoin as legal tender (2021). In theory, gains on Bitcoin are not taxed there. In practice, this country remains poorly suited to structured wealth expatriation: limited financial infrastructure, institutional instability, absence of a real international business community. Interesting on paper, risky in reality.
Comparison table
| Country | Crypto capital gains rate | Conditions | Real attractiveness |
|---|---|---|---|
| France | 30% (flat tax) | French tax residency | Low for holders |
| Portugal | 0% / 28% | Exemption if > 365 days held | Very high (long-term) |
| UAE (Dubai) | 0% | Residency visa required | Very high |
| Germany | 0% / marginal rate | Exemption if > 12 months | High (long-term) |
| Switzerland | 0% (private portion) | Outside professional activity | High, wealth tax applies |
| El Salvador | 0% (BTC) | Institutional instability | Limited |

Reporting obligations: what you cannot ignore
Declaring foreign digital asset accounts
Since 2020, French tax residents have been required to declare their digital asset accounts held with foreign entities (form 3916-bis, to be attached to the annual income tax return). This obligation applies to all foreign exchanges: Binance, Coinbase, Kraken, Bybit, etc.
Failure to declare exposes you to a fine of 750 euros per undeclared account, rising to 125 euros per month of delay and potentially up to 10,000 euros if the account is in a non-cooperative state. These amounts may seem modest, but they compound, and non-declaration can also constitute evidence of tax fraud in a broader audit.
Declaring disposals (form 2086)
In each year of disposal, you must complete form 2086 detailing the crypto capital gains and losses realised. This form automatically calculates the taxable base using the total portfolio value method and weighted average cost.
Maintaining a precise record of all your transactions (purchase price, date, euro value at the time of purchase) is essential. Specialist tools such as Waltio or Koinly can generate these reports automatically from your exchange histories.
Pitfalls to avoid
Pitfall 1: fictitious domiciliation
This is the main risk for expats with large crypto portfolios. Officially relocating to Dubai while maintaining real life in France (family, apartment, activity, daily spending) changes nothing from a tax perspective. The tax authority can reassess residency and claw back all capital gains.
Pitfall 2: forgetting to declare foreign accounts
Even without a disposal, even without realised gains, you must declare your accounts on foreign exchanges as long as you are a French tax resident. Many recent expats are still unaware of this.
Pitfall 3: returning to France within 5 years
If you sold crypto after leaving France and return within 5 years, some of the gains may be clawed back under French taxation depending on applicable tax treaties and anti-abuse rules. Worth monitoring if you are considering a temporary expatriation.
Pitfall 4: reclassification as professional trading activity
If you trade actively with leverage, execute a large number of transactions, or your gains represent a predominant share of your income, some tax authorities (including France’s) may reclassify your activity as professional trading. The applicable rates are then significantly higher than the flat tax.
Pitfall 5: ignoring the new DAC8 rules
The European DAC8 directive has, since 2026, required exchanges operating in Europe to automatically transmit information on their EU-resident clients’ transactions to tax authorities. The era of crypto tax opacity in Europe is over. Transactions are traceable.
Frequently asked questions
If I change my tax residency, do I pay tax on my unrealised crypto gains?
No, in principle. Cryptocurrencies are not currently within the scope of the French exit tax. You do not pay tax on unrealised gains when you leave. Taxation only occurs upon actual disposal. This is precisely what makes the timing of sales so important.
What is the difference between a foreign exchange and a personal wallet?
A foreign exchange (Binance, Coinbase, Kraken) is an account held with a third-party entity: it must be declared on form 3916-bis. A non-custodial wallet (hardware wallet, self-managed Metamask) is not an account held with an entity: it is not subject to the same declaration obligation, even though it must naturally be included in your capital gains calculation.
Are staking rewards and airdrops taxable?
In France, income from staking is taxed as non-commercial profits (BNC) at the time of receipt, based on its euro value at the date of receipt. Airdrops are treated differently depending on their nature. This regime is distinct from the capital gains disposal regime. Check the latest positions of the French tax authority on impots.gouv.fr.
How do I prove my foreign tax residency to the French tax authority?
You need to build a solid dossier: foreign residency certificate (or equivalent), local lease, local bank statements, visa or residency permit, documented effective presence (tickets, passport stamps), and if possible termination of professional activity in France. The larger the portfolio, the more thoroughly documented the file needs to be.
Crypto taxation for expats is a field where mistakes are costly and where the right decisions need to be made in advance, not under pressure. Tax residency is the pivot of any strategy; the timing of your disposals is its practical expression. For a broader view of the tax dimension of your expatriation, see our guide on expat taxes.
The information in this guide is current as of the third quarter of 2026. Cryptocurrency taxation is a rapidly evolving area, both at the French level and across Europe (DAC8, MiCA). Before any significant financial decision, consult a tax adviser specialising in digital assets and international taxation.
