Koinly Review 2026: Is It Still the Best Crypto Tax Software?

Crypto tax software lives or dies on one question: can it turn a messy year of trades, swaps, staking rewards, and wallet transfers into a report your tax authority will actually accept? Koinly has been the default answer for several years running — but the space has matured, regulations have tightened, and the free tiers that once felt generous have been trimmed across the board. So is Koinly still the one to beat in 2026? After working through what it does, where it strains, and how its pricing compares, here’s the honest picture.

At a Glance: Koinly 2026

What Koinly Does Well

Koinly’s core strength is that it doesn’t assume you file US taxes. Most crypto tax tools are built around IRS forms with everywhere else treated as an afterthought; Koinly produces jurisdiction-specific reports for over 20 countries — a real difference if you file in the EU, UK, Australia, or Canada. It connects to more than 850 exchanges, wallets, and blockchains through direct API or read-only keys, and auto-categorizes the large majority of transactions — staking, yield, liquidity mining, margin trades, and loans included — without line-by-line manual cleanup.

For 2026 specifically, Koinly is in a stronger position than most rivals because it tackled Form 1099-DA — the new US broker reporting form — head-on, and turns your activity into clean Form 8949 and Schedule D figures plus a TurboTax export. Its reconciliation tools are also worth noting: they flag missing cost-basis entries and surface gaps from closed exchanges or missing history before you generate a final report, not after.

The interface stays beginner-friendly despite all that depth, which is why it remains the lowest-friction path to a usable filing document for most people. We feature Koinly as our top overall pick in our best crypto tax software comparison for exactly this reason.

Pricing — What You Actually Pay

The model is simple: the free tier lets you connect everything, track your portfolio, and preview your tax liability — you only pay when you want to download the actual report. Paid plans are annual and tiered by transaction volume, running from roughly $49 for light filers up to a few hundred dollars for high-volume traders. For anyone with more than about 100 transactions across multiple platforms, that’s competitive value against the hours of manual reconciliation it replaces. The important nuance: the free plan is preview-only, so budget for a paid plan if you actually need to file.

Where Koinly Falls Short

Two honest limitations. First, there’s no dedicated audit support — if your situation is complex enough that you might face questions from a tax authority, you’ll want an accountant in the loop rather than relying on the software alone. Second, very complex DeFi — deep multi-protocol activity with unusual contract interactions — can still produce edge cases that need a manual review before filing. That’s true of every tool in this category, but it’s worth setting expectations: Koinly removes 90% of the work, not 100%.

Who Koinly Is Best For

Koinly is the right default for the large majority of investors: anyone with activity spread across multiple exchanges and wallets, anyone filing outside the US who’s tired of US-centric tools, and anyone who wants to preview their liability for free before committing to a paid report. If you’re a casual holder with a single exchange and a handful of trades, the free tier plus a $49 plan is more than enough. If you run an active, multi-chain DeFi strategy, Koinly still handles most of it — just budget time to review the gnarly edge cases, and consider an accountant if an audit is even a remote possibility.

The Bottom Line

In 2026, Koinly remains the tool to beat for everyday crypto tax filing — broad coverage, genuine multi-country support, 1099-DA readiness, and a free tier that lets you see your numbers before you pay. It isn’t flawless: no audit support and the usual DeFi edge cases keep it from being a complete hands-off solution. But for the lowest-friction path from messy on-chain history to a report your accountant can use, Koinly is still the one we recommend first.
