Crypto tax regularization

Crypto tax regularization allows you to secure your digital assets, substantiate your wealth to third parties (banks, notaries), and mitigate penalties in the event of a tax audit.

Crypto-asset taxation is now a central priority for the French tax administration. The annual reporting by exchange platforms and the Automatic Exchange of Information between States, effective as of January 1, 2026, make non-disclosure particularly risky. Many individual investors hold undisclosed foreign crypto accounts or have incorrectly reported their capital gains and other operations (staking, airdrops, etc.). Voluntary tax disclosure is therefore an essential step to preempt sanctions, demonstrate good faith, and secure one’s estate.

What is crypto tax regularization?

Crypto tax regularization consists of correcting past tax returns to include transactions, accounts, or income related to digital assets that went unreported. It helps avoid heavy fines and reduces risks associated with a tax audit. Given the specificities of crypto taxation, regularizing these operations requires a meticulous reconstruction of transaction histories.

Crypto tax regularization for individuals

The question of disclosure typically arises for individuals who:

Did not declare crypto capital gains during taxable events (e.g., conversion to fiat or purchase of goods and services) via Form 2086;
Omitted foreign crypto accounts opened on platforms such as Kraken, Coinbase, or other exchanges not established in France, via Form 3916-bis;
Hold income from Decentralized Finance (DeFi)—staking, lending, airdrops, mining—without integrating them into their income tax returns.

Crypto tax regularization for professionals

Though less frequent, regularization can also involve company executives, startup founders, or entrepreneurs who received tokens, stock options, or digital asset income without anticipating the tax treatment. In these cases, the process aims to secure the company’s compliance while limiting personal risks related to the taxation of such income.

Why hire a tax attorney for crypto tax regularization?

Crypto regularization is a sensitive procedure requiring a fine-tuned analysis of flows, mastery of tax rules, and a tailored strategy. Hiring a specialized tax attorney allows you to:

Adapt the strategy: Every situation is unique; we determine whether it is best to disclose immediately, request a tax ruling, or engage in limited dialogue on a specific point of law. A prior audit allows for an upfront determination of costs and audit risks.
Limit sanctions: Voluntary disclosure significantly reduces the risk of tax fines (notably for foreign accounts) and surcharges.
Demonstrate good faith: A taxpayer’s voluntary initiative is always viewed more favorably than a correction imposed following an audit.
Secure your estate: Correctively integrating crypto-assets into income tax returns and succession planning.
Preempt a tax audit: Preparing a robust file limits the risk of litigation during any subsequent examination.

Our methodology in crypto tax regularization

At ORWL_, our support for crypto tax regularization is based on a proven methodology:

Preliminary transaction audit: We conduct a full analysis of transactions, on-chain histories, and exchange statements to trace movements economically and materially, justifying the source of funds and identifying taxable events.
Review of past filing obligations: We review foreign account disclosures and capital gains filings to identify omissions, allowing us to precisely quantify the financial cost of regularization.
Definition of a disclosure strategy: We determine the best filing options and approach to adopt with the tax authorities based on the nature and severity of the breaches.

This method ensures a seamless and secure officialization of crypto portfolios that often remained “off the grid” due to unclear rules or habit, allowing our clients to enjoy their wealth without difficulty.

Frequently asked questions (FAQ) related to crypto tax regularization

How do I regularize my undeclared crypto capital gains?

Regularization requires filing amended tax returns. For individuals, gains from taxable disposals must be reported on Form 2086. This requires a faithful reconstruction of transactions from on-chain history and exchange records. A tax attorney ensures the accuracy of calculations and engages the administration on solid ground.

Must I declare accounts held on Binance, Kraken, or Coinbase?

Any foreign crypto account opened with a platform not domiciled in France must be declared via Form 3916-bis, even if no transactions were made. Failure to do so results in a flat fine (€1,500 per account, rising to €10,000 for non-cooperative jurisdictions). Note that while Binance has a French entity, others like Coinbase or Kraken are established abroad.

What are the statutes of limitations for crypto regularization?

The standard statute of limitations is three years. However, this is extended to ten years in the event of a failure to declare accounts opened abroad. Voluntary disclosure prior to any audit limits the risk of this extension.

What are the penalties for not declaring foreign crypto accounts?

Failure to disclose is sanctioned by a flat fine of €1,500 per account (Art. 1736, IV of the CGI). These fines are added to the evaded tax, late interest (0.20% per month), and penalties for deliberate breach (40%) or fraud (80%). Regularization significantly reduces this exposure.

Does regularization protect against a future crypto tax audit?

It does not grant immunity, but it drastically reduces the risk of aggravated assessments. By coming forward voluntarily, the taxpayer demonstrates good faith and avoids the heaviest surcharges.

How long does the procedure take?

The audit and reconstruction phase can take weeks to months depending on volume. Once amended returns are filed, the administration typically takes three to six months to process them. The entire process generally spans six months to one year.

What is the payment deadline after a crypto rectification?

Tax authorities usually issue the notice of assessment for the additional taxes a few weeks or months after filing. It is possible to request payment plans or installments from the public accountant.

How much are the legal fees for crypto regularization?

Fees vary based on the complexity (number of accounts, transaction volume, variety of protocols). We offer either flat-fee packages for the audit and filings or hourly billing for full representation. At ORWL_, fees are defined transparently from the start.
