Crypto Tax Tools Compared: CryptoTaxCalc vs Koinly vs CoinLedger vs CoinTracker
The short answer: if you want a quick, private, per-trade estimate with no sign-up and no data upload, CryptoTaxCalc is free and runs entirely in your browser. If you need a full tax return with automatic exchange syncing and official forms, Koinly, CoinLedger or CoinTracker are the established paid options — they cost $49–$299 depending on how many trades you have. Here's how they actually compare.

When to use CryptoTaxCalc
CryptoTaxCalc is built for a specific job: fast, private estimates without handing your trading history to a third party. It's the right fit when:
- you want a quick tax estimate on a single trade before you sell;
- you're checking whether to harvest a loss and how much it would save;
- you'd rather not connect your exchange accounts or upload CSV files to a startup's servers;
- you batch-import a CSV and want a short-term/long-term breakdown locally.
It is not a replacement for tax-filing software. It doesn't sync your exchanges, generate Form 8949, or file for you. For that, you still need one of the tools below — but you can use CryptoTaxCalc for free to sanity-check their numbers.
When to use Koinly, CoinLedger or CoinTracker
The paid tools do the heavy lifting that a browser-only calculator can't: they pull transactions from every exchange and wallet you use, match buys to sells across years, and produce the forms your tax authority wants. Use them when:
- you traded across multiple exchanges or wallets and need one unified history;
- you have hundreds or thousands of transactions;
- you need official tax forms (Form 8949, Schedule D, HMRC reports, etc.) to file;
- you want automated cost-basis matching, transfer detection and audit trails.
The trade-off is privacy and cost: these tools store your complete trading history on their servers (encrypted, but still third-party-held) and charge $49–$399 per tax year depending on transaction volume.
Pricing reality check
A common misconception: "I'll just use the free tier." The free tiers of Koinly and CoinTracker let you see a summary but typically lock the downloadable tax report behind a paid plan. If you actually need to file, budget for the paid tier. CoinLedger does not offer a full free tier at all — its plans start at the entry report level. CryptoTaxCalc is the only one in this comparison that charges nothing, ever, because it doesn't run a server that processes your data.
Honest bottom line
If you're an active trader needing a complete, audit-ready return, Koinly, CoinLedger or CoinTracker are worth the money — pick whichever supports your exchanges and countries best. If you want a zero-cost, zero-sign-up estimate that never sees your data, CryptoTaxCalc is the only game in town for that specific use case. You can even use both: calculate on CryptoTaxCalc for privacy, then verify against your paid tool's output before filing.
