Koinly and CoinTracker are the two crypto tax tools most people end up deciding between, and the honest answer to “which is better” is that it depends on what your crypto activity actually looks like. As a CPA firm that has cleaned up reports from both, we can tell you where each one shines and where each one needs a human.
Here is the short version: Koinly tends to win for active, multi-chain, DeFi-heavy traders, and CoinTracker tends to win for cleaner portfolios that live mostly on major US exchanges. Below is the full breakdown.

Quick Answer: Which Should You Pick?
If you trade actively across many exchanges and chains, or you have real DeFi activity, Koinly usually fits better thanks to broader coverage and more flexible cost basis handling. If your portfolio is simpler, lives mostly on major US exchanges, and you value a clean interface plus easy TurboTax export, CoinTracker is often the smoother ride. Both can produce an accurate report. Neither does DeFi perfectly on autopilot.
Side-by-Side Comparison
| Factor | Koinly | CoinTracker |
|---|---|---|
| Exchange & wallet coverage | Very broad | Broad, strong on major US exchanges |
| DeFi & multi-chain | Wider chain/protocol support | Solid, but narrower for deep DeFi |
| Cost basis methods | Flexible (FIFO, HIFO, and more) | Supported, fewer options in lower tiers |
| Interface | Functional, data-dense | Clean, portfolio-friendly |
| TurboTax export | Yes | Yes, tight integration |
| Per-wallet (2025 rule) | Updated | Updated |
| Pricing | By transaction count | By transaction count |
| Best for | Active / DeFi / multi-chain | Simpler portfolios on major exchanges |
Where Koinly Wins
- Coverage. Broad support across exchanges, chains, and protocols, which matters for active and multi-chain traders.
- Cost basis flexibility. More method options, useful for optimizing gains and matching your accountant’s approach.
- DeFi reach. Wider protocol recognition, though it still needs review.
Where CoinTracker Wins
- Interface and portfolio tracking. Cleaner to navigate, with strong ongoing portfolio views, not just tax season.
- US exchange integration. Tight connections with major US exchanges and a smooth TurboTax handoff.
- Simplicity. For a straightforward portfolio, it is often the faster path to a finished report.
What Neither Tool Does Well on Its Own
Both platforms share the same real-world limits, and pretending otherwise sets you up for a wrong report.
Both also depend entirely on getting every wallet and exchange connected. A single missing source produces $0 cost basis and phantom gains on either tool. And both surfaced surprises this year as the 2025 per-wallet rule (Rev. Proc. 2024-28) changed how basis is tracked.
The CPA’s Bottom Line
For a clean portfolio, either tool plus careful review will get you a correct return. Choose CoinTracker for simplicity, Koinly for coverage.
But the tool is not the hard part once your activity gets complex. High volume, meaningful DeFi, multiple wallets across chains, years of unreconciled history, or a 1099-DA that conflicts with your own records: in those cases the software is a starting point, not the finish line. A crypto CPA who works in both tools daily will reconcile the account, apply the per-wallet rules correctly, and give you a report you can actually defend. Plenty of our clients run the software themselves and bring us in for the reconciliation and the sign-off.
Key Takeaways
- Koinly for active, DeFi, multi-chain traders. CoinTracker for simpler portfolios on major exchanges
- Both price by transaction count, so cost scales with how much you trade
- Both updated for the 2025 per-wallet rule. Confirm your settings apply it
- Neither tool automates DeFi accurately. Manual review is required on both
- For complex activity, the software is the start and a crypto CPA is the finish
