When it comes to crypto taxes, accuracy isn’t optional. An incorrect report can lead to underpayment penalties, missed deductions, or an IRS audit. Koinly is designed to deliver precise, country-compliant tax calculations — but how does it actually achieve that? This guide covers the reports Koinly generates, how it handles complex scenarios like crypto-to-crypto trades and transfer fees, and what to do when something looks off.
What Tax Reports Does Koinly Generate?
Koinly produces a comprehensive suite of reports depending on your country:
For US users: IRS Form 8949 (capital gains and losses), Schedule D summary, TurboTax-compatible CSV, TaxAct import file, and a complete transaction history.
For international users: Country-specific capital gains reports, income summaries, and formats compatible with local filing requirements for the UK (HMRC), Canada (CRA), Australia (ATO), Germany, and more.
All reports are available in CSV, Excel, and PDF formats, giving you flexibility to share with accountants or upload directly to tax software.
Is Koinly Accurate?
Koinly takes accuracy seriously and works closely with leading accounting firms in key markets to ensure compliance. The platform has completed formal tax methodology reviews with firms in the United States, Canada, and other major markets. These audits verify that Koinly’s calculations align with local regulations — from FIFO and LIFO in the US to the Adjusted Cost Basis method in Canada and Share Pooling in the UK.
That said, accuracy depends on the quality of your input data. If transactions are missing, mislabeled, or imported from unsupported sources without proper formatting, the calculations may be off. This is why Koinly flags issues with the “Review Needed” warning.
What Does the “Review Needed” Warning Mean?
When you see a “Review Needed” notice on your Tax Reports page, it means Koinly has identified potential issues with your data that could affect accuracy. Common triggers include: negative balances (selling more of a coin than you appear to own), missing cost basis for certain assets, unmatched transfers, or duplicate transactions. Koinly provides a guided workflow to help you resolve each issue before generating your final report.
How Does Koinly Handle Crypto-to-Crypto Trades?
In most countries, including the US, UK, and Canada, exchanging one cryptocurrency for another is a taxable event. For example, if you swap Bitcoin for Ethereum, the IRS treats this as a sale of Bitcoin at the market price of the Ethereum you received. Koinly automatically identifies these events, calculates the gain or loss on the disposed asset, and records the new cost basis for the received asset.
If your country does not treat crypto-to-crypto swaps as taxable, Koinly includes a setting called “Realize gains on crypto-to-crypto trades” that can be toggled off.
Are Transfer Fees Taxable in Koinly?
When you transfer crypto between your own wallets, the transfer itself is not a taxable event. However, the network fee you pay (in cryptocurrency) may be treated as a disposal and could trigger a small capital gain or loss. Koinly tracks this automatically and includes a setting called “Treat transfer fees as disposals” that you can toggle based on your jurisdiction’s rules.
Does Koinly Work With My Country’s Tax Rules?
Yes. Koinly applies country-specific cost-basis methods and tax rules automatically based on your selected country. This includes FIFO, LIFO, HIFO, and average cost methods for the US; Share Pooling (Section 104) for the UK; ACB for Canada; and specific methodologies for Australia, Germany, France, Japan, and over a dozen other countries. You can also manually select your preferred cost-basis method if your accountant recommends a specific approach.
