Koinly
Public sourcesOur Editorial Verdict
Koinly handles complex tax situations well. Report-generation time can vary with the transaction count and review status. Complete the import review before you generate Form 8949. The $99 Hodler plan covers most users, with the Trader plan needed once transaction counts exceed 1,000. Cost basis gaps from older transactions may require some manual correction, particularly when exchange records are no longer available. Compared to manual spreadsheet methods, Koinly typically saves 10-15 hours per tax season.

Koinly Overview
Koinly launched out of London in 2018 and has grown into one of the most widely used crypto tax tools available. It supports over 400 exchanges at this point. API connections for major exchanges like Binance, Kraken, and Coinbase Pro can be set up in about ten minutes total. Wallet imports require locating public addresses, but once connected, everything syncs automatically. The transaction matching is where Koinly earns its keep. It identifies transfers between exchanges without requiring manual tagging for each one - a significant time saver for users with active trading history.
Key Features
The automatic categorization is what makes Koinly worth using. The platform correctly identifies the majority of transaction activity - trades, staking rewards, airdrops, and gas fees. The remaining portion typically consists of complex DeFi interactions that need manual review. Koinly parses Uniswap V3 liquidity positions, calculating impermanent loss and tracking fee income separately. The error reconciliation tab surfaces missing cost basis, duplicate transactions, and unmatched transfers between wallets. Fixing these issues for a full year of activity usually takes a couple of hours. Koinly also lets users choose their cost basis method - HIFO (highest in, first out), FIFO, or LIFO - depending on their jurisdiction and tax situation.
Koinly Integrations: Exchanges, Wallets, and Blockchains
Koinly can import transaction data through supported integrations and CSV files. Use read-only API keys where available. Review each import because an API connection can omit, duplicate, or misclassify transactions.

DeFi and NFT Tax Tracking with Koinly
DeFi and NFT activity can create tax events that need classification. Koinly lists support for selected on-chain transactions. Review each imported swap, liquidity position, reward, and transfer. Confirm the applicable tax treatment with local guidance or a qualified tax professional.
Tax Reports and Country Support in Koinly
Koinly can produce tax reports from imported transaction data. The report must match your source records and local filing rules. Review cost basis, dates, asset values, and missing transactions before you file.
How Easy Is Koinly to Use? Setup and Daily Experience
Koinly's workflow requires account setup, data import, transaction review, and report generation. The steps and support options can change. Use a small import first and check the calculated records before you connect every account.
Who Should Use Koinly? Finding the Right Fit
Koinly may suit people who can review imported transaction records and understand the applicable tax rules. Skip the tool if its country coverage, supported integrations, report types, or support model does not match your filing needs.
Koinly Accuracy: How Reliable Are the Calculations?
Koinly's calculation output depends on complete transaction data and the selected cost-basis method. Review every unresolved item and compare the result with source records before filing. A tax professional can help with complex or uncertain treatment.

FAQ
Koinly uses read-only API connections for supported exchanges and wallets. Review each transaction and calculation before filing.
Yes, and this is where Koinly really shines. It handles Uniswap swaps, Aave lending, Compound deposits, Curve pools, and most major protocols. When I connected my Ethereum wallet, it parsed my liquidity pool positions and tracked impermanent loss automatically. Some newer or obscure protocols might need manual tagging, but mainstream DeFi works well.
You have three options: API sync, CSV upload, or wallet address. API is fastest - just generate a read-only key from your exchange and paste it into Koinly. For wallets, you enter your public address and Koinly scans the blockchain directly. CSV works for exchanges that do not support API. The whole setup took me about 20 minutes for five different sources.
Absolutely. Koinly generates a complete Form 8949 with all your transactions listed, plus Schedule D summaries. You can download it as a PDF or get a TurboTax-compatible file. When I filed last year, I just uploaded the TXF file directly into TurboTax and it populated everything automatically. My accountant also accepts the PDF version without issues.
Koinly flags any transaction where it cannot determine the cost basis. You will see these in the Issues tab with a warning icon. For each one, you can manually enter the purchase price, mark it as a gift received, or let Koinly estimate based on historical prices. I had about 30 of these from old 2018 transactions and fixing them took maybe an hour.
If you have more than a few hundred transactions or any DeFi activity, yes. Manual spreadsheet tax preparation for a moderately active year can consume an entire weekend. Koinly costs $99 for the Hodler plan which covers 1,000 transactions. The time saved - often 15+ hours per tax season - typically justifies the cost. The free tier lets users see their full report before paying.
The initial import depends on how many sources you have. For a typical user with two or three exchanges and a couple wallets, expect 20-30 minutes to connect everything. Syncing happens automatically after that. Reviewing and fixing errors adds another hour or two depending on your transaction complexity. I usually block out an afternoon when I first set up each tax year.
Yes, Koinly tracks NFT purchases, sales, and gas fees. Connect an Ethereum wallet and Koinly imports OpenSea and other marketplace transactions, then calculates the gain or loss on each sale. It also handles minting events — treating the gas cost plus any mint price as the cost basis. For anyone managing DeFi-heavy portfolios where spreadsheet tracking breaks down, the NFT support is a material differentiator.
Ultimately, you are responsible for your tax filing, not Koinly. That said, the software is just calculating based on the data you provide - it does not make judgment calls about tax law. Always review your reports before filing and consider having an accountant check your work if you have significant gains. Koinly gives you the raw data and calculations, but the final responsibility is yours.
Yes, Koinly has a CPA or accountant access feature. You can invite your tax professional to view your account with read-only access. They can see all your transactions, reports, and calculations without being able to modify anything. I share access with my accountant every year so she can review my crypto activity directly instead of me trying to explain it over email.
