Go to KoinlyWhat is Koinly
Koinly is a tax service focused on an international audience. Founded in 2018 in Singapore, headquartered in London, CEO Robin Singh. It automatically imports trades from exchanges and wallets, calculates profits and losses under your country's rules, and produces ready-made forms: UK Capital Gains Summary, German Anlage SO, Australian myTax, Canadian Schedule 3, and others.
Who it's for
Crypto investors in countries where CoinLedger has limited presence: UK, Germany, France, Sweden, Netherlands, Austria, Canada, Australia, New Zealand, Japan, South Korea. It also works in the US, but there the choice between Koinly and CoinLedger is less clear-cut.
Problem it solves
Unlike CoinLedger, Koinly ships ready-made tax forms for local requirements in 20+ countries from day one. For a European or Australian investor, that means generating a report and taking it straight to the tax office, rather than adapting a US form manually.

Competitors and alternatives
CoinLedger is the main direct competitor. Koinly wins in non-US jurisdictions (20+ countries with ready-made forms vs 7 for CoinLedger), offers more DeFi integrations, and supports more coins. CoinLedger is better for US residents due to direct TurboTax integration and the Expert Review option. CryptoTaxCalculator is a solid choice for Australia and the UK, but falls behind Koinly on DeFi. ZenLedger is popular in the US. For Germany, there is local CoinTracking, but it is more complex and less automated.
What users say
Trustpilot 4.6/5 on 2,241 reviews (February 2026), one of the highest ratings in the category. Most common complaints: inaccurate detection of internal transfers for unusual wallets, confusion around lost/stolen transactions (requiring manual tagging), slower support during peak season. In December 2025, there was an email leak via Mixpanel. Wallet and tax data were not affected, but it is worth factoring in.
Why we included it
For CoinMagnetic readers outside the US, Koinly is our first pick. The UK, Germany, Sweden, and other major jurisdictions are all covered. DeFi categorization works better than any other tax software we have tested. For active airdrop farmers, Koinly automatically detects claim transactions and marks them as income.
FAQ
Koinly vs CoinLedger: which one to pick?
If you're in the US, CoinLedger for TurboTax. In any other country from the 20+ list, Koinly. For active DeFi users, Koinly is the clear call: the categorization is better.
Does Koinly work for users in restricted regions?
There's no local tax form for every jurisdiction. You can get a detailed profit/loss report in USD and adapt it manually. Many of our readers use Koinly as a data source and build their final filing from there.
How much does the annual subscription cost?
From $49 for Newbie to $279 for Pro. There's a free plan with a portfolio tracker, but the report cannot be downloaded on it.
Is it safe after the Mixpanel leak?
The December 2025 leak only affected email addresses via a third-party processor. Wallet data and tax forms were not compromised. Koinly has since disconnected Mixpanel and conducted an audit. You can decide how much weight to give that incident.
Is DeFi and NFT supported?
Yes, 7,200+ protocols. Liquidity pools, staking, yield farming, and airdrop claims are all detected automatically. NFT transactions on Ethereum, Polygon, Arbitrum, Base, Avalanche, and BSC are supported.
Is tax loss harvesting available?
Yes, from the Hodler plan ($99). It shows losing positions that can be closed to reduce your tax bill.
