Best free crypto tax software, with the catch stated.

There is no pricing section for free software, so this is the price of leaving free — what the first paid step costs on each platform, checked in November 2026:

• Koinly: $49 per tax year unlocks downloadable reports (up to 100 transactions; $99 to 1,000). You pay per filing year.
• CoinLedger: $49 per tax year (Hobbyist, up to 100 billable transactions; $99 Investor to 1,000). Readers of this site get 10% off with code CRYPTOTAX10, which makes its first paid step the cheapest exit from free anywhere in this table.
• CoinTracker: $59 per year (Base, up to 100 transactions). More than the others for one year — but the subscription also generates forms for past years in your account, which per-year platforms charge for separately.
• TokenTax: $49 per tax year — but with no free tier in front of it, that $49 is also your cost of finding out whether the platform fits you at all.

• Every platform’s free tier breaks at the same wall: the downloadable report. Form 8949 and Schedule D output is the product; the preview is the advertisement. Plan on paying someone if your history is too large to transcribe by hand.
• Free previews break on bad imports. A preview computed from an incomplete import looks authoritative and is wrong. Duplicated exchange connections and unclassified transfers are the usual causes — the preview is only as good as the reconciliation you do inside it.
• Our free tools break on volume and complexity. Honestly stated: manual entry stops being sane somewhere past a few dozen disposals, and our calculators estimate rather than generate filing documents. Past that point the paid platforms earn their fee — which is exactly the handoff this page exists to make.
• Free breaks when something goes wrong in February. Free tiers come with community help and documentation, not a human who knows your return. If your import turns into a research project at deadline time, the paid tier’s support — or a professional’s hour — stops being a luxury. Reconcile early, while free is still a choice rather than a trap.

1. Estimate free first. Run your biggest trades through the capital gains calculator and check any 1099-DA against your own basis with the reconciler. For simple histories, this is the whole workflow.
2. Import free into two platforms. Koinly for the 10,000-transaction ceiling, CoinLedger for the full-report preview. Two independent totals that agree are strong evidence your records are complete.
3. Not sure you need software at all? Take the two-minute quiz — it routes simple histories back to the free tools and complex ones to the right tier.
4. Pay once, at the platform whose preview reconciled. Download the report, file, and keep the audit trail. Next year starts free again.

The newest filing task — checking your return against the broker’s Form 1099-DA — is also, conveniently, one of the most free-able. The form’s weakness is structural: for transferred-in and pre-2026 assets it reports proceeds with no basis, so the reconciliation is arithmetic on records you already own.

• Free, completely: our 1099-DA reconciler computes the gain the form implies versus the gain your basis produces, per lot, with the short/long-term split — in your browser, no account. Paired with the 1099-DA guide, a simple history is fully handled at $0.
• Free as a preview: Koinly and CoinLedger will import your full exchange history and show you their version of the same reconciliation. Use it as a cross-check on your own numbers; pay only if you want their report document.
• Where free stops: scale and mess. Hundreds of lots across wallets, or basis that must be reconstructed from fragments, is where the paid platforms’ lot-matching earns its fee — the arithmetic is free everywhere, the bookkeeping is not.

One discipline matters more than tooling: reconcile before filing season peaks, while your records are findable and brokers can still issue corrected forms without a queue.

• We take pricing, free tiers, and billing models from the vendors’ own public pages, cross-checked against independent roundups — and we date every check, because these numbers move.
• We do not accept payment for placement or ranking. Where a link on this page can earn us a commission, the disclosure at the top and bottom says so, and says which vendor it applies to.
• We do not publish user counts, star ratings, or testimonials we cannot verify, and we label integration counts as vendor-reported because every vendor counts differently.
• When sources disagree, the vendor’s current pricing page is the final authority — confirm there before buying.

• The full software hub — all four platforms, all tiers.
• Koinly vs CoinLedger — the two $49 platforms head to head.
• CoinTracker vs CoinLedger — subscription vs per-year math.
• Do I need software? — the two-minute routing quiz.
