The five areas head to head
AI AnalysisFees & Costs
The tool is free to use after signup — importing, automatic categorisation, portfolio tracking and DeFi and NFT coverage require no payment. What is chargeable is access to the reports, the tax-loss harvesting tool and priority support. Plans run per tax year: around $49 for 100 transactions, $99 for 1,000, $249 for 10,000 and $499 for up to 100,000. There is no permanently free report. As of August 2026.
Not enough reviews available.
Usability & User Experience
Setup is more demanding than at the beginner-oriented competitors — in exchange the tool handles complex transaction histories that others fail on. A suggestion engine categorises ambiguous entries automatically. For simple portfolios the feature set is arguably oversized. As of August 2026.

Features & Offering
With more than 2,900 integrations across exchanges, wallets and blockchains, coverage is the broadest in this comparison — particularly relevant for DeFi, Web3 and NFT activity, where other tools run out of road early. Country-specific tax formats cover several jurisdictions. In October 2025 Crypto Tax Calculator was renamed Summ, marking the shift from a pure tax calculator to a broader digital-asset management platform. As of August 2026.

Verdict
In our overall rating Waltio leads with 4.5 against 2.9 for Summ.
For most investors Waltio is therefore the better choice.
Summ (formerly Crypto Tax Calculator) is especially valued for its industry-leading number of over 2,900 integrations. No other platform in this comparison offers such broad coverage of exchanges, wallets, and blockchains. Support for FIFO, LIFO, HIFO, and ACB as tax methods, along with country-specific tax formats for over 20 countries, makes the tool appealing for internationally active crypto investors.
Particularly noteworthy is the comprehensive Web3 and DeFi support, which also fully captures NFT transactions. The developer API enables advanced use cases and integrations into existing workflows. Prices ranging from 49 to 299 USD per year are considered moderate by market standards and offer tiered options for different portfolio sizes.
A free plan is not currently available, which raises the barrier to entry compared with some competitors. Setup is described as moderately complex, and audit support is still unavailable.
In addition, personal communication with the team — particularly interactions with Mathieu M. — raised concerns regarding the company’s level of professionalism and seriousness in handling certain matters. Given past industry scandals where early warning signs were often reflected in communication practices and internal handling of issues, these interactions may be viewed by some users as a potential red flag worth considering during due diligence.
Waltio is built for investors who want to get their crypto transactions in order without deep tax knowledge. Setup is guided step by step, and with more than 700 supported exchanges, wallets and blockchains it copes with portfolios spread across several platforms. DeFi is not an afterthought here: staking, lending, NFTs and airdrops are all captured in full, which is more than many cheaper tools manage.
The pricing makes for an easy start. Portfolio tracking is free indefinitely; you only pay once you want to generate an official tax report. Plans run from €39 to €999 a year depending on transaction volume – trade very actively and you will land at the upper end quickly. FIFO, LIFO and HIFO are all available as calculation methods, covering the approaches most European tax regimes expect.
The clearest limitation is where the product comes from. Waltio grew up in the French market, and you can see it in the export formats: alongside a general tax statement it produces France's form 2086, with no equivalent for other countries. Germany is on the covered list, but the depth of localisation does not match what specialist local providers offer. If you file outside France and need a report your tax office will accept without rework, check that before you buy.
On balance, Waltio is a sound choice for European investors with DeFi-heavy portfolios who appreciate the free entry point. For a purely German or Austrian tax case, a provider with stronger local coverage remains the more obvious pick.
