Crypto tax software compared: Koinly, CoinTracker, CoinLedger — pricing and accuracy
The moment a crypto portfolio crosses from a few casual trades into active involvement — multiple exchanges, a wallet or two, some DeFi positions, maybe an NFT mint — the tax question stops being theoretical. Every swap is a disposal, every transfer between exchanges is a potential audit flag if misreported, and a year of DeFi activity can generate thousands of taxable events that no human can reasonably inventory by hand. This is the gap that crypto tax software exists to fill: connect your exchanges and wallets, reconstruct your transaction history, apply the cost basis rules of your country, and produce the forms your accountant actually files. Three products dominate that market — Koinly, CoinTracker and CoinLedger — and they are similar enough in concept that choosing between them comes down to differences that only appear in use: how well each imports your data, how it handles the messy edge cases like missing cost basis and staking rewards, what its pricing does as your transaction count grows, and whether its support team can actually resolve a reconciliation problem or merely point you at documentation. Those differences matter more than feature-list comparisons suggest, because in this category the product is not the interface — it is the accuracy of the numbers underneath it. A tax report that is beautifully formatted and subtly wrong is worse than no report at all.
What these tools actually do — and what they cannot do
Before comparing the three, it is worth being precise about the category. Crypto tax software is not a filing service and not a legal advisor: it ingests transaction history, classifies events, computes gains and losses under a chosen method (FIFO, HIFO, or specific identification depending on jurisdiction) and outputs reports — most commonly Form 8949 and Schedule D for US users, capital gains summaries for UK and EU users, and income reports for staking, mining and interest. All three products in this comparison perform this core loop, and all three support the major exchanges, the major blockchains and the major wallets.
The part that separates quality products from adequate ones is edge-case handling, and the edge cases are where crypto taxes actually live:
- Missing cost basis. Coins bought in 2017 on an exchange that no longer exists, or received before you started keeping records. Each tool handles this differently — some let you assign a historical price manually, some assume zero cost basis (which overstates gains), some flag the gap prominently. How a tool treats unknown-basis holdings materially changes your reported gains.
- Transfer matching. Moving crypto from Exchange A to your own wallet is not a taxable event, but naive software counts it as a sale and a purchase. All three products attempt to match transfers across wallets; the accuracy of that matching — especially when timestamps drift or addresses are reused across platforms — is a genuine differentiator and a common source of user corrections.
- DeFi complexity. Liquidity provision, yield farming, lending collateral and DEX swaps generate transaction patterns that resist simple classification. Tools that offer native DeFi integrations for major protocols handle these cleanly; tools that rely on generic contract-parsing label many DeFi events ambiguously, leaving the user to correct classifications manually.
- NFTs. Mints, purchases, sales and royalty flows — particularly when priced in ETH — require cost basis tracking across two assets at once. NFT support ranges from functional to fragile across the category.
With that frame in place, the comparison itself can be concrete rather than generic — because the three products differ most precisely in how much of this mess they resolve automatically versus how much lands on the user’s spreadsheet skills.
The head-to-head: pricing, coverage and support
The three products cover the same conceptual ground, but their pricing structures, geographic focus and support quality diverge in ways that matter over a full tax year. The snapshot below reflects publicly listed pricing tiers as of 2026; all three revise pricing periodically, and all three offer free plan tiers that let you import data and preview calculated gains before paying — which is the correct way to evaluate any of them.
| Dimension | Koinly | CoinTracker | CoinLedger |
|---|---|---|---|
| Free tier | Import data, preview gains, no download | Import data, preview gains, limited download | Import data, preview gains |
| Paid tiers (approx.) | $49–$279 per year by transaction count | $59–$649 per year by transaction count | $49–$299 per year by transaction count |
| Exchange integrations | 300+ exchanges and wallets; among the broadest | 300+; strong on major US venues | 300+; strong on major US venues |
| DeFi handling | Dedicated protocol integrations plus manual classification | Improving, historically weaker on complex DeFi | Solid generic handling; fewer protocol-specific integrations |
| NFT support | Functional, including ETH-priced sales | Supported, with some edge-case gaps | Supported at a basic level |
| Tax report focus | Broad international coverage — 100+ country templates | Deepest on US; good UK, Canada, Australia | Deepest on US; covers India prominently |
| Support quality | Live chat with generally competent responses; paid tiers faster | Email and chat; historically uneven response times | Responsive chat; leaner team, faster on simple issues |
| Consensus reputation | Strongest for complex, multi-year international portfolios | Strongest for straightforward US exchange activity | Strongest value for US-centric portfolios under ~5,000 transactions |
Reading the table honestly: for a US-based user with activity mostly on Coinbase and a couple of wallets, all three will produce correct-enough results, and the choice can be made on price and interface preference. The differentiation shows up at the edges. Koinly’s historical strength has been international tax coverage and multi-year portfolio reconstruction, which is why it is the most common recommendation among expats and users with tangled histories. CoinTracker’s strength is its polish and its integration depth with mainstream US exchanges, along with partnerships that embed it directly in products like MetaMask — convenient, occasionally to the point of lock-in. CoinLedger competes by being the value option: for portfolios that are not exotic, its lower tiers deliver the same outcome for less money, and its Indian market focus makes it the default recommendation there, a niche the other two treat as secondary.
Pricing in practice: where costs actually bite
The sticker prices above describe the cheapest tier; real pricing depends on transaction count, and this is where the three products’ models produce different outcomes. All three gate full report downloads behind paid tiers and scale those tiers by the number of transactions in the year — so a heavy DeFi user generating 10,000 events pays more than a buy-and-hold investor, regardless of portfolio size.
What drives real-world cost:
- Transaction count, not portfolio value. Someone with $5 million sitting in cold storage and three transactions pays the lowest tier; someone with $8,000 spread across yield farming pays a high one. If your activity is transaction-heavy, compare the highest tier you would need — not the advertised entry price.
- Multi-year history inflates counts. Importing five years of history when you first sign up can push you into a higher tier immediately, since prior-year disposals must be computed to establish opening cost basis. Koinly and CoinLedger both handle this gracefully; CoinTracker’s tier thresholds have historically been less generous at high counts.
- Annual repurchase is the norm. Pricing is annual, and the tax years you actually file determine what you pay: many users need two or three tax years’ reports (current year, and prior years if catching up), effectively multiplying the sticker price.
Practical buying advice follows from this: import all your data on the free tier first, let each tool compute your gains, and only then choose — because the free previews reveal both the true tier you need and, more importantly, whether the tool’s classification of your actual transactions matches your understanding of them. The differences between tools are invisible until your data is inside; paying before importing is how users discover pricing surprises.
Accuracy: where the tools differ when it matters
Accuracy in this category is not about arithmetic — all three compute gains correctly given the same inputs. It is about the inputs: whether the import captured everything, whether transfers matched correctly, whether classifications match reality. Errors in these layers produce wrong tax numbers that the interface still displays with full confidence, and the user, trusting the formatting, files them.
Where each product’s accuracy genuinely stands:
- Koinly earns its reputation through editability: nearly every computed number can be inspected, traced to source transactions and manually corrected when the automation errs. Its transfer matching across many exchanges is mature, and its handling of multi-year gaps — assigning reasonable historical prices for missing basis — is the most developed of the three. The trade-off is that the interface surfaces complexity: users sometimes face more decisions upfront.
- CoinTracker is accurate for what it is designed around — mainstream exchange activity and simpler wallets — and its polished interface lowers the error rate for inexperienced users by making mistakes visible early. Its historically weaker areas are complex DeFi patterns and some cross-venue transfer matching; users with heavy on-chain activity report more manual corrections than Koinly users with identical data.
- CoinLedger computes accurately for the transaction patterns it handles well — exchange trading, standard staking, simple DeFi — and its leaner feature set means fewer places to go wrong. Its weakness is the inverse of Koinly’s: exotic transactions are more likely to land in a generic category the user must fix, and protocol-specific integrations are fewer.
Two accuracy habits matter regardless of which tool you choose. First, reconcile the totals yourself before filing: compare the tool’s computed cost basis for your holdings against your own records, and investigate any gap — the largest single source of wrong crypto tax reports is missing import history, not bad math. Second, treat the tool’s output as a draft for a tax professional in any year with unusual events: audits, gifts, airdrops, DeFi liquidations and lost wallets all have tax treatments that software defaults do not necessarily match for your jurisdiction.
The differences that do not show in feature lists
Support quality and data ergonomics shape the experience more than any feature matrix, and they differ noticeably across the three:
- Koinly’s live chat is the strongest support channel of the three, with responses that usually engage the actual reconciliation problem rather than reciting documentation; its paid tiers shorten wait times further. Its interface, however, is denser — users occasionally need the documentation to find where a setting lives.
- CoinTracker’s interface is the most approachable, and its wallet and exchange connection flow is the smoothest; its support has historically been slower and less consistent, which matters most in April, when everyone’s questions arrive at once.
- CoinLedger’s support is responsive for its size, and its interface is clean; the trade-off is a narrower feature surface, which for its target user is mostly a benefit — fewer knobs means fewer mistakes.
Data portability is worth checking at signup: all three can export your full transaction ledger as CSV, which matters if you switch tools later or hand your data to an accountant. None of the three locks your underlying data away, but the completeness of what exports — classifications versus raw transactions — varies, and Koinly’s exports are the most complete in preserving your corrections.
Which one fits which user
The honest recommendation matrix is smaller than the marketing suggests:
- Choose Koinly if your history is messy — multiple exchanges across years, missing records, international reporting, or heavy DeFi — and you want the tool most likely to reconstruct it correctly with the most manual-correction leverage.
- Choose CoinTracker if you are US-based, your activity is concentrated on major exchanges, and you value a polished, low-friction experience over maximum flexibility; the embedded wallet integrations are a real convenience for MetaMask-centric users.
- Choose CoinLedger if you are value-conscious with a moderately complex US portfolio, or you are in India, where its local tax report support is the best of the three and its pricing is the most accessible.
The overlap zone — a US user with a few thousand transactions on two exchanges — is served equally by all three, and there the deciding factors are interface preference and the current pricing tier your transaction count lands in. Checking the free preview across two tools before committing costs an hour and routinely saves both money and correction time.
Conclusion
Koinly, CoinTracker and CoinLedger have converged on the same core competence — accurate gain computation from well-imported data — and diverged on the margins that complexity exposes. Koinly is the strongest for tangled histories and international coverage; CoinTracker is the most polished path for mainstream US exchange activity; CoinLedger is the value choice for portfolios whose complexity does not require the others’ depth. Pricing across all three scales with transaction count rather than portfolio size, which makes heavy DeFi users the segment where tier selection matters most, and the free import-plus-preview flow is the correct way to evaluate any of them before paying.
The deeper point about this category survives the comparison: no tax software replaces reconciliation. The tools compute what you give them, and the accuracy of any report is bounded by the completeness of the import history underneath it — which is why the users who get clean results are the ones who connect every account, verify transfer matching, review DeFi classifications and compare computed cost basis against their own records before filing. Software turns a week of spreadsheet labor into an afternoon of review; it does not turn a neglected portfolio into an accurate one. Among the three, any of them will serve you well if you feed it honestly — and the differences between them, while real, are smaller than the difference between a reconciled portfolio in any of them and an unreviewed export in all of them.
