What is Koinly?

Koinly is a specialized web application built to solve the critical pain point of cryptocurrency taxation. Its core purpose is to eliminate the manual, error-prone process of tracking trades, calculating cost basis, and determining capital gains or losses across potentially dozens of platforms. By automatically syncing data from exchanges, wallets, and blockchains, Koinly creates a unified financial picture. It then applies the relevant tax rules (like FIFO, LIFO, or HIFO) to calculate your tax liability and generates official reports such as IRS Form 8949, Schedule D, and international equivalents. It's primarily for individual crypto traders, DeFi users, mining operators, and the accountants who serve them.

Key Features of Koinly

Automated Data Import & Sync

Koinly supports over 1,000 integrations, including all major exchanges (Coinbase, Binance, Kraken), wallets (MetaMask, Ledger, Trezor), and blockchains. You can connect via API for real-time sync or upload CSV files. The platform automatically classifies transactions (trades, income, gifts, loans) and reconciles your portfolio, saving countless hours of data entry.

Accurate Capital Gains Calculations

The software automatically calculates your capital gains and losses for every disposal, applying your chosen accounting method (e.g., FIFO). It handles complex scenarios like transfers between your own wallets, margin trading, futures, and staking rewards, ensuring your cost basis is correctly tracked for accurate tax liability.

Compliant Tax Report Generation

With one click, generate tax reports formatted for your country's tax authority. Key reports include the Capital Gains Report (IRS Form 8949), Income Report, and a comprehensive Tax Summary. Reports are updated annually to reflect the latest tax laws, giving you confidence in your filing.

Tax-Loss Harvesting & Planning Tools

Koinly isn't just for year-end. Use its dashboard to view your unrealized gains/losses in real-time, identify opportunities for tax-loss harvesting to offset gains, and forecast your potential tax liability. This proactive feature helps you make smarter trading decisions throughout the year.

Portfolio Tracking & Performance

Beyond taxes, Koinly acts as a unified portfolio tracker. See your total net worth, asset allocation, and historical performance across all your connected accounts. This gives you a holistic view of your crypto investments in one dashboard.

Who Should Use Koinly?

Koinly is essential for any crypto participant with a tax filing requirement. This includes active day traders and swing traders managing high volumes of transactions, long-term 'HODLers' with complex cost-basis histories, DeFi users engaging in yield farming, lending, and liquidity pools, crypto miners and stakers receiving income, and freelance professionals or businesses paid in cryptocurrency. It's equally valuable for accountants and tax advisors who need to efficiently prepare accurate returns for their crypto-holding clients.
