Best Free Crypto Tax Software: What Is Actually Free?

“Free crypto tax software” is usually a paywall map, not a yes-or-no product category.

One tool lets you import for free but charges for the report. Another shows the portfolio for free but locks filing output. Another lets you preview a calculation that still contains unresolved exceptions.

So I would compare free plans by where the paywall appears in the evidence chain.

Draw the five-stage paywall map

The best free plan is the one that lets you learn enough before the paywall to decide whether paying is rational.

Koinly places the paywall late enough to diagnose a large ledger

Koinly’s current free plan allows unlimited wallets and up to 10,000 transactions. Users can view imported transactions, gains on individual trades and the tax summary.

The paywall appears at the report stage: the free plan cannot generate tax reports and excludes some advanced tools such as cost analysis and bulk editing in Excel.

That makes Koinly the strongest free starting point when the first job is investigation. A user can discover missing purchases, transfer issues and other reconciliation problems before deciding whether the report is worth buying.

The caveat is important: if the account exceeds the free transaction ceiling, calculations can stop until the user moves to a suitable paid plan.

CoinLedger lets you reach the report workflow—but exceptions still matter

CoinLedger is useful for importing, reviewing and previewing a tax workflow before purchasing the final report.

Its current skipped-transaction feature is the reason I would inspect the preview carefully. Problematic records can be excluded from tax-report calculations while the report itself still generates successfully.

So a free or preview-stage total is informative only after checking whether skipped transactions exist and whether they are material.

CoinLedger’s paywall is relatively easy to understand because tax reports are priced by billable transaction count for the tax year.

CoinTracker’s free value is mainly workflow fit

CoinTracker’s strongest differentiation is its US filing sequence: account review, transaction review, Form 1099-DA reconciliation and final tax forms.

The free layer is useful for deciding whether the portfolio and account structure fit that ecosystem. Full tax-report access sits in the paid plan structure.

For a US user, that can be enough to answer an important question before paying: does this product organise my actual accounts in the way I want to file?

But workflow progress is not the same as ledger completeness. CoinTracker’s guided flow can allow users to skip flagged-transaction review and continue with current data.

CoinTracking is the free-plan question I would verify live

CoinTracking has a long-standing ledger and reporting model with a free tier, but the useful ceiling depends heavily on the current transaction, import and feature limits.

I would not publish a timeless “free up to X” claim unless the live plan page supports it at the time of use.

The right test is whether the free allowance can contain the complete history required for the intended job. A free plan that forces the user to omit older records is not free reconciliation; it is a partial dataset.

Do not compare free plans by transaction count alone

A larger number can look generous and still be the wrong metric.

Transaction counting differs across products. Order fills, rewards, spam, imports and other records can be grouped or treated differently. More importantly, a high free limit does not help if:

• the required historical source cannot be imported;
• the product hides unresolved records;
• the normalised data cannot be exported usefully;
• the required local tax report does not exist;
• the free layer ends before the user can test the difficult transactions.

Use one deliberately imperfect test ledger

Before paying any vendor, give the free layer enough real complexity to expose its boundaries:

1. one active exchange connection;
2. one historical CSV;
3. one self-custody wallet;
4. one transfer with a network fee;
5. one missing acquisition;
6. one staking or income event;
7. one complex DeFi or NFT event if relevant.

Then ask:

• Which records imported?
• Which warnings appeared?
• Can the missing acquisition be traced?
• Are any transactions skipped or ignored?
• Can I export the cleaned history?
• Which exact output becomes paid?
• What plan would the complete ledger require?

When paying is cheaper than staying free

Free software becomes expensive when it causes repeated manual reconstruction or traps corrections inside a product the user later abandons.

I would pay only after three conditions are met:

1. the complete ledger can be represented;
2. material exceptions can be explained;
3. the paid output is exactly the form, report or filing handoff required.

Payment should unlock a useful output from a ledger you already understand—not buy hope that the software will somehow fix the data afterward.

My ranking of the free stage

Koinly is the strongest free diagnostic environment for a large or messy ledger because the paywall comes after substantial import and reconciliation visibility.

CoinLedger is useful for testing a simpler review-to-report path, but skipped transactions must be inspected before trusting the preview.

CoinTracker is most useful free as a fit test for a US portfolio-to-filing workflow, particularly when Form 1099-DA will matter.

CoinTracking is worth testing when the user wants a granular ledger environment, but its current free limits should be verified immediately before committing a large history.

The larger rule is the one I would keep: free import, free reconciliation, free calculation and free filing are four different promises.
