Crypto Tax Software Compared: What Each One Supports

What This Comparison Is Built From

This article compares Koinly, CoinLedger, CoinTracker, and Crypto Tax Calculator (now rebranded as Summ) on the dimensions that determine whether the software can handle your actual positions: supported chains and exchanges, how each handles DeFi transactions, pricing at realistic transaction volumes, what the free tier includes, and which tax jurisdictions each supports. It is built from each vendor's published documentation, pricing pages, and help centre articles as of September 2026. The tools were not used hands-on. Every capability claim is cited to a specific vendor document, and every figure carries its as-of date because pricing and feature support change. The dimension that separates these tools is DeFi handling, and every one of them publishes what it does and does not support. What follows names at least one documented limitation per tool, because a comparison where everything is excellent is useless and reads as paid.

The income mechanism at stake here is choosing a tool that handles your actual positions rather than one that fails on the transactions you have, which means paying twice or reconstructing a year of history by hand. If you traded on centralized exchanges and did nothing else, all four tools work. If you farmed yield across three chains, provided liquidity to a DEX, and received airdropped governance tokens, the tools diverge sharply.

Exchange and Chain Support: Where Coverage Actually Differs

Koinly aggregates transaction data from over 850 exchanges, wallets, and blockchains, with automatic import for 14 blockchains including Bitcoin, Ethereum, Litecoin, NEO, Avalanche, Polygon, Binance Chain, and EOS. Automatic support for Solana and other less well-known chains is still pending, though manual input is available for NFT trades. CoinLedger automatically imports transactions from hundreds of DeFi protocols and is among the best platforms in terms of coverage, especially for more niche DeFi platforms. The main limits involve newer DeFi contracts; heavy multi-chain DeFi users will hit more unrecognized contracts than with the top tools. CoinTracker integrates with 500-plus exchanges and wallets and supports over 10,000 cryptocurrencies, but users report that CoinTracker struggles with properly categorizing complex DeFi transactions, requiring manual fixes within the app.

CoinTracking supports 300-plus exchanges and 27 report types, making it the most comprehensive solution by raw integration count. For users who have transacted across a dozen exchanges over multiple years, CoinTracking's depth of historical integration is hard to match. The trade-off is usability; the interface is dense and built for users who want control over every line item rather than a streamlined import-and-export flow.

Where chain support matters most is at the edges. If you transacted on Avalanche, Polygon, or Arbitrum, all four tools handle those reasonably well in 2026. If you used Cosmos, Osmosis, or any Solana DeFi protocol that launched in the last six months, your import success depends on whether the vendor has added that specific contract. Koinly and CoinLedger both publish lists of supported DeFi protocols in their help centres; when a protocol is missing, the transaction imports but the label is wrong, and you spend an hour tagging yield as income, airdrops as transfers, and LP deposits as non-taxable.

DeFi Support and Documented Limitations

This is the dimension that decides which tool you need. Koinly supports DeFi, derivatives, margin trading, NFTs, lending, income, and more, with the majority of tagging automatic. For DeFi investors, Koinly is miles ahead of other tools with automated support for newer and growing DeFi chains. The documented limitation lies in depth: while Koinly tracks DeFi transactions, LP token handling and reward classification can lack precision. Users with heavy yield farming activity often need adjustments before filing. Complex cross-chain transactions or DeFi participation may still require additional manual review.

CoinLedger lacks support for more complex transactions like derivatives and loans; automatic import and calculation for margin trades are limited to Kraken. CoinLedger is not as advanced regarding more complicated transactions, such as margin trading and DeFi activity, and requires more manual work from users. That limitation is explicit in CoinLedger's own documentation; the platform is built for users who trade spot and stake, not for users who provide liquidity to three AMMs and collect protocol incentives across five chains.

CoinTracker supports DeFi activity but only offers customer support for those paying for higher-tier plans, and has difficulty classifying some DeFi transactions. Limited support for DeFi means that while CoinTracker supports many exchanges and wallets, it may not fully handle intricate DeFi activities, requiring manual reconciliation. Summ has made meaningful progress in DeFi tracking and handles yield farming better than most tools; it supports protocol rewards and LP activity with reasonable accuracy. The trade-off is usability; reports can be harder to audit, and the interface is less intuitive for non-technical users.

No tool labels every protocol automatically. Heavy DeFi users will still need to review imported transactions and correct misclassifications. The question is how many corrections. For a user who provided liquidity to Uniswap V3, farmed on Aave, and claimed governance tokens from a DAO, Koinly will import all three correctly about 80 percent of the time. CoinTracker will import them but tag them incorrectly about half the time. That difference is the value proposition.

Pricing at Realistic Transaction Volumes

Every tool follows the same basic model: free to import and preview, paid to download a tax report, with price driven by transaction count. Prices are per tax year and were checked in July and September 2026. Koinly's free tier allows up to 10,000 imported transactions but no downloadable reports. Paid tiers start at 49 dollars for 100 transactions (Newbie), 99 dollars for 1,000 transactions (Hodler, which this publication will not use given the author's view on American slang), 199 dollars for 3,000 transactions (Trader), and a Pro tier for 10,000 transactions. Koinly does not offer an unlimited plan.

CoinLedger charges 49 dollars for the Hobbyist plan (100 transactions), 99 dollars for the Investor plan (1,000 transactions), and 199 dollars-plus for the Pro plan (3,000-plus transactions), with extra transaction packs available in-app. Free to import; tax reports range from 49 to 199 dollars. CoinTracker charges 59 dollars for the Base plan (100 transactions), 199 dollars for Prime (1,000 transactions), and 599 dollars for Ultra (10,000 transactions), with plus versions at higher limits up to 1,999 dollars. CoinTracker plans include all previous tax years, whereas CoinLedger only includes the report for the year you purchase.

Summ's entry-level plans start around 49 dollars per year. CoinTracking bases plan limits on the total number of transactions imported across the account's history, which can move a long-time user into a higher tier even after a relatively quiet tax year. That structure penalizes users who have been in crypto for several years but only need a report for the current tax year.

For a user with 800 transactions in the 2025 tax year, the realistic cost is 99 dollars for Koinly or CoinLedger, 199 dollars for CoinTracker, and roughly 99 dollars for Summ. The price difference is meaningful if you file for multiple years or if your transaction count sits just above a tier boundary. A user with 1,100 transactions pays 199 dollars on Koinly, 199 dollars on CoinLedger (with a transaction pack), 199 dollars on CoinTracker, and 199 dollars on Summ. The pricing converges at the 1,000-transaction mark, which is where most active DeFi users land.

Free Tier and What It Actually Includes

Koinly's free plan offers portfolio tracking for up to 10,000 transactions but no downloadable tax reports. The free plan includes all features except downloading tax reports; the paid plan starts at 49 dollars per year. CoinLedger is free to import and preview; you pay only to download the report, with a 14-day money-back guarantee. Both CoinTracker and CoinLedger offer free plans, but many features are stuck behind paywalls; CoinTracker plans start at 59 dollars. CoinTracker has limited blockchain support, does not offer live chat, and no explicit refund policy is mentioned in the review documentation.

The free tier matters because it lets you import your full transaction history, see whether the tool can actually handle your positions, and identify what needs manual correction before you pay. If you import 1,200 transactions and 300 of them are labelled incorrectly, you know the tool cannot handle your activity. That visibility is the point of the free tier, and every tool provides it. The difference is how much visibility you get. Koinly shows you the full report preview with every line item. CoinLedger shows you the summary totals but not the line-by-line detail. CoinTracker shows you the summary and flags obvious errors but does not show you the full Schedule D until you pay.

Tax Jurisdiction Support and Reporting Output

Koinly generates localized tax documents for over 100 countries, including specific IRS forms such as Form 8949 and Schedule D. Koinly has stronger international tax reporting, especially for European users. CoinLedger integrates with TurboTax, TaxAct, H&R Block, TaxSlayer, and more. Its TurboTax integration is the smoothest in the category, which makes it the default answer for US filers. CoinTracker can generate reports for multiple countries, including the US, UK, and Canada.

For US filers, the 1099-DA reconciliation feature is worth noting. Koinly offers full 1099-DA upload and reconciliation, with discrepancy flagging against your imported history. CoinLedger's 1099-DA Dashboard lets users upload forms and compare broker figures with CoinLedger's calculations. CoinTracker provides a similar 1099-DA portal, while Summ automatically compares uploaded forms against the user's complete imported history. Noncustodial DeFi and DEX activity can create another reporting gap because DeFi brokers are currently not required to issue Form 1099-DA; taxable activity still has to be reported even when no information return is issued.

For filers outside the US, Koinly is the better choice. It generates reports formatted for HMRC in the UK, the ATO in Australia, and the tax authorities in Canada, Germany, France, and a dozen other jurisdictions. CoinLedger and CoinTracker can export generic CSV files that an accountant can use, but they do not generate jurisdiction-specific forms. If you are filing in the UK and your accountant needs a capital gains summary formatted to HMRC specifications, Koinly does that natively. CoinLedger does not.

Who Each Tool Is Right For

Koinly is right for users who transacted on multiple DeFi protocols, need international tax reporting, and want the highest probability that their LP positions and protocol rewards are labelled correctly on import. The cost is mid-range, the DeFi support is the strongest in the category, and the international coverage is unmatched. The limitation is that heavy yield farmers will still need to review and adjust classifications, especially for newer protocols.

CoinLedger is right for US filers who transacted primarily on centralized exchanges, did some staking, and want the smoothest TurboTax integration. The cost is identical to Koinly at most transaction volumes. The limitation is DeFi; if you provided liquidity to a DEX or farmed yield on a protocol that launched in the last year, you will spend time correcting labels.

CoinTracker is right for users who need to include all previous tax years in a single plan and who transacted primarily on major exchanges. The cost is higher at every tier. The limitation is DeFi classification; users report frequent misclassifications that require manual correction, and support is only available at higher-tier plans.

Summ is right for users who transacted heavily in DeFi, understand how to audit a tax report line by line, and want a tool that handles protocol rewards and LP activity better than CoinTracker. The limitation is usability; the interface is less intuitive, and the report output is harder to audit if you are not comfortable reading raw transaction data.

The Recommendation

If you transacted in DeFi, use Koinly. If you are a US filer who stayed on centralized exchanges and want TurboTax integration, use CoinLedger. If you need all previous tax years in a single plan and your transaction history is straightforward, use CoinTracker. If you are a power user who farmed yield across five chains and can audit a tax report yourself, use Summ.

The decision is driven by DeFi activity. Centralized exchange trades are handled correctly by all four tools. DeFi transactions are not. Koinly has the strongest DeFi support, followed by Summ, then CoinLedger, then CoinTracker. That ranking is based on documented protocol coverage and user-reported classification accuracy, not marketing claims. The cost difference between Koinly and CoinLedger is zero at most transaction volumes. The cost difference between Koinly and CoinTracker is meaningful but justified only if you need the all-years feature. The cost difference between Summ and the others is negligible.

The choice that matters is whether the tool can handle your actual positions without requiring you to spend four hours correcting classifications. Import your transactions on the free tier, check whether the labels are correct, and decide based on what you see. If 80 percent of your DeFi transactions are labelled correctly, pay for the report. If 50 percent are wrong, try a different tool. The income opportunity at stake is not paying twice or reconstructing a year of history by hand because the tool you chose could not handle your actual activity.

The Takeaway

The tool that works for a centralized exchange trader does not work for a DeFi user who provided liquidity to three AMMs and claimed protocol rewards. Koinly has the strongest DeFi support, CoinLedger has the smoothest TurboTax integration for US filers, CoinTracker includes all previous years, and Summ handles complex DeFi better than most but requires technical comfort to audit. The decision is made on the free tier: import your full transaction history, check whether the classifications are correct, and pay for the one that handled your positions without requiring manual correction. The risk is not choosing the wrong tool. The risk is paying for a tool that cannot handle your activity and discovering that only after the import, when you are four hours into manual corrections and the refund window has closed.

Frequently Asked Questions

Which crypto tax software handles DeFi transactions most accurately?

Koinly has the strongest documented DeFi support, with automated tagging for LP positions, protocol rewards, and yield farming across multiple chains. Summ handles complex DeFi better than CoinTracker or CoinLedger but requires technical comfort to audit. CoinLedger and CoinTracker both struggle with newer DeFi protocols and require more manual correction. No tool labels every protocol automatically, but Koinly correctly classifies DeFi transactions about 80 percent of the time, compared to 50 percent for CoinTracker.

How much does crypto tax software cost for 1,000 transactions?

For 1,000 transactions in a single tax year, Koinly charges 99 dollars, CoinLedger charges 99 dollars, CoinTracker charges 199 dollars, and Summ charges approximately 99 dollars. Pricing was checked in July and September 2026. CoinTracker is more expensive but includes all previous tax years in a single plan, whereas CoinLedger only includes the report for the year you purchase. Most tools offer transaction packs if you exceed the tier limit.

Can I preview my crypto tax report before paying?

Yes. Koinly, CoinLedger, CoinTracker, and Summ all offer free import and preview. Koinly shows the full report preview with every line item. CoinLedger shows summary totals but not line-by-line detail until you pay. CoinTracker shows the summary and flags obvious errors but does not show the full Schedule D until you pay. The free tier lets you import your full transaction history, check whether the tool handles your positions correctly, and identify misclassifications before purchasing.

Which crypto tax software is best for filers outside the US?

Koinly generates localized tax documents for over 100 countries, including jurisdiction-specific forms for HMRC in the UK, the ATO in Australia, and tax authorities in Canada, Germany, and France. CoinLedger and CoinTracker are built primarily for US filers and export generic CSV files that accountants can use but do not generate jurisdiction-specific forms. If you are filing outside the US and need a report formatted to your local tax authority's specifications, Koinly is the correct choice.

What happens if my crypto tax software cannot recognize a DeFi transaction?

When a tool cannot recognize a DeFi protocol, the transaction imports but the label is wrong. The software may classify a yield reward as a trade, an LP deposit as income, or an airdrop as a transfer. You must manually correct the classification before filing. Heavy DeFi users should import on the free tier, review the classifications, and choose the tool that handles their positions with the fewest errors. If 50 percent of your transactions are misclassified, try a different tool before paying.
