Who is Waltio? History and key figures 2026
Founded in 2019 by Pierre Morizot and Benjamin Chevallereau, Waltio is a French startup specializing in simplifying crypto tax declarations for individuals and professionals. Waltio offers a platform that allows you to track all digital assets, calculate gains and losses, and generate tax documents compliant with current regulations.

Waltio review: how good is the Waltio offering?
The Waltio offering is built on a SaaS platform designed to automate and ensure the reliability of digital asset tax management. Its main objective is to simplify the declaration of gains from cryptocurrency operations, in compliance with the French tax framework. To do this, Waltio automatically aggregates transactions carried out on various crypto exchange platforms via API connections or CSV file imports, and then performs a rigorous calculation of capital gains and losses, applying French tax rules based on the method of calculating the global portfolio and the total acquisition price.
The Waltio tool then generates official tax documents, including Form 2086, which is often complex to fill manually. Beyond calculation, Waltio offers a clear and interactive interface, detailed reports, and a crypto wealth-tracking dashboard. The entire solution is designed to streamline the declaration process, minimize potential errors, and provide a structured view of crypto activity, essential for effective and compliant wealth management.
How much does Waltio cost in 2026?
Waltio offers a range of subscriptions tailored to the needs of cryptocurrency investors, based on the annual transaction volume.
Waltio Free offering (€0)
The Waltio Free offering is completely free and does not require a credit card or subscription. It primarily allows unlimited tracking of your crypto portfolio by easily linking exchanges and wallets. You can also manually calculate your P&L, i.e., your profits and losses. However, automatic performance calculation is only available with paid plans. This Free offering also provides access to the foreign account declaration form, a requirement for French investors. It is therefore an excellent solution for portfolio tracking, but to stay fully up to date with your tax obligations, you will need to upgrade to a higher plan.
Waltio Lite offering (€39 per year)
Designed for users making up to 50 transactions per year, the Lite subscription at €39 offers the essential features to track your crypto portfolio and generate the necessary tax documents. You will have the foreign account declaration (Form 3916bis) and income declaration (Cerfa 2086) included, to be in compliance with your tax declaration obligations.
Waltio Starter offering (€99 per year)
Designed for those making between 50 and 1,000 transactions annually, the Waltio Starter includes, in addition to the Lite features, a tax certificate certifying the conformity of the declarations.
You also get a guide to filing your tax return on Impots.gouv.fr
From this plan onward, the Waltio tool also accounts for staking income.
Waltio Smart offering (€249 per year)
Suitable for investors making between 1,000 and 10,000 transactions per year, this Smart Waltio subscription offers advanced features such as document export, optimization of fees and staking, as well as monthly account synchronization.
Waltio Unlimited offering (€999 per year)
Designed for the most active traders, with no transaction limit, this Unlimited Waltio plan includes, in addition to the previous benefits, exclusive services such as assistance in case of a tax audit, bank fund repatriation, and priority support.
These Waltio prices allow users to choose the plan best suited to their crypto activity, while benefiting from personalized support to ensure the conformity of their tax declarations.
Waltio review: who is Waltio for?
The Waltio offering targets primarily French-resident individual investors who hold or trade cryptocurrencies, regardless of their experience level or transaction volume. Whether a casual investor who has completed a few trades in a year or an active trader carrying out thousands of transactions, Waltio provides a solution tailored to each profile through its tiered pricing.
The Waltio platform is also suitable for people who have used multiple crypto exchanges, which complicates the traceability of operations, as well as those engaging in activities like staking, airdrops, or DeFi, which are often difficult to declare manually. Finally, Waltio will also interest professional profiles or entrepreneurs operating in the Web3 space, though its core target remains individuals.
By centralizing data and automating tax calculations, the Waltio tool proves particularly useful for anyone seeking to declare their digital assets in compliance with French regulations, without resorting to a chartered accountant.

Our Waltio opinion
Here at Café de la Bourse, we consider Waltio’s offering essential for any French investor wishing to declare their crypto assets in full compliance with the current tax regulations.
Calculating crypto capital gains can quickly become a real headache, especially when transactions multiply and involve several digital assets. Buying Bitcoin, swapping it for Ethereum, converting it to Ripple, and finally ending up in Solana… then attempting to manually reconstruct the gain realized in euros is virtually impossible.
Added to this is the diversity of crypto platforms used, each with its own transaction history formats. In this context, Waltio stands out for its ability to centralize, normalize, and rigorously calculate all operations, while generating tax documents that meet the authorities’ requirements. A tool we deem not only useful but nearly indispensable at a time when crypto taxation is becoming more structured and tax audits are more frequent.
