AI Analysis

Fees & Costs

Summ
Summ

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.

Koinly
Koinly

Importing is free: up to 10,000 transactions can be loaded, wallets and exchanges connected without limit, and capital gains previewed. Payment is only due when downloading the finished tax report, charged per tax year: around $49 for 100 transactions, $99 for 1,000, $199 for 3,000 and $299 from 10,000 upwards. Anyone needing a report once a year pays for that year only. As of August 2026.

Usability & User Experience

Summ
Summ

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.

Koinly
Koinly

Setup is regarded as the most approachable entry point among tax tools: exchanges connect by API or CSV and categorisation runs largely automatically. Users with heavy DeFi activity still need to reconcile manually. As of August 2026.

Features & Offering

Summ
Summ

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.

Koinly
Koinly

More than 800 exchanges and wallets are connected. Country-specific tax reports are available for the US, UK, Canada, Australia, Germany and around 20 further jurisdictions, which matters because the output has to match the local filing format. Portfolio tracking and iOS and Android apps round this out. As of August 2026.

SummOur Opinion

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.

KoinlyOur Opinion

Koinly is especially valued for its beginner-friendly interface and broad coverage of more than 800 exchanges and wallets. The setup is considered straightforward, which is particularly helpful for users who are dealing with the tax reporting of cryptocurrencies for the first time. With support for FIFO, LIFO, HIFO, and ACB as tax methods, Koinly covers the calculation methods commonly used in Germany. DeFi, staking, and mining transactions are also automatically recognized and categorized.

The free portfolio tracking makes it easy to get started without having to pay right away. The mobile app for iOS and Android is positively regarded as a practical addition to the web version. The pricing tiers from USD 49 to 279 per year are considered moderate in market comparison, although the costs at high transaction volumes are seen as room for improvement. Koinly offers country-specific tax reports for more than 20 countries, underlining its international usability.

The German localization is occasionally described as room for improvement, as the focus is more on the English-speaking market. Audit support is also currently missing, which may be relevant for users with more complex tax requirements. Overall, Koinly is seen as a solid choice for beginners and users with medium transaction volumes who are looking for an intuitive tool with broad exchange coverage and mobile access.
