CoinTracker

CoinTracker is a portfolio tracker that also does tax, and that ordering is the real difference between it and the tax-first tools beside it in this directory. It maintains a live picture of what you hold across every exchange and wallet you connect, with a mobile app worth opening, and produces the tax forms as an output of the same data rather than as a once-a-year exercise you start from scratch. It has official integrations with Coinbase, TurboTax and H&R Block, which removes a genuine amount of manual work.

The pricing shape matters more than the exact numbers, which change. Tracking is free with no cap on transactions, so you can connect everything and watch the portfolio without paying. Downloading tax forms requires a paid plan, tiered by how many transactions you have, and — unlike the per-tax-year purchase some competitors use — it is billed as an annual subscription. If what you want is a live portfolio you look at all year, that is the right shape. If what you want is forms once each spring, compare the total against a tool that charges per year filed, because the same job can cost meaningfully more here. Check their pricing page rather than any review, including this one; the tiers have moved several times.

User data has been exposed twice, both times through a supplier rather than CoinTracker itself. In December 2022 a compromise at the email provider SendGrid exposed email addresses for more than 1.5 million CoinTracker users. In November 2025 the analytics provider Mixpanel was breached and attackers exported email addresses, locations derived from IP, device metadata and — this is the part that matters — summaries of users' transactions. In neither case were funds, passwords or keys involved, and in both cases the failure was genuinely at a vendor. That distinction is true, and it is also cold comfort: you chose CoinTracker, and CoinTracker chose them.

The second leak is the serious one, and specifically because of what this product is. A tax tool used once a year holds a snapshot. A portfolio tracker holds a continuously updated picture of what you own, which means a leak from one carries an implication about how much crypto a named person has. Attach that to an email address and an approximate location and you have the ideal input for targeted phishing, and for the small but real category of attacks that stop being digital. The pattern is the same one that runs through this whole site: the breach is not the loss. The message three weeks later, from someone who knows more about you than a stranger should, is the loss. Nobody from CoinTracker will ever contact you asking for a seed phrase, a private key, or for you to move funds anywhere.

Connect exchanges with read-only API keys and nothing more. A tracker only ever needs to read. A key with withdrawal permission grants far more than the job requires, and the two incidents above are a decent argument for granting the minimum to any third party, however well run.

One thing worth naming plainly, given where you are reading this. CoinTracker is the tax tool several large exchanges recommend inside their own apps. That is a commercial arrangement, the same species as the one disclosed at the top of this page. It is not a reason to distrust the product — the integrations are real and they do save work — but "my exchange suggested it" is a marketing placement rather than a verdict, and it is worth knowing which one you are reading.

It is not a tax adviser. Staking, DeFi, airdrops and NFTs remain genuinely unsettled in many jurisdictions, and software has to choose a treatment and then present it with the same confidence as a simple spot trade. For a straightforward year it is fine. For anything with real complexity, treat the output as a well-organised starting point for a professional — see the records you need before tax time for what to keep so that either route works.
