Koinly is one of the more polished cryptocurrency tax platforms available, and it genuinely simplifies what would otherwise be a nightmare of spreadsheet calculations. It supports over 800 exchanges, wallets, and blockchains, making it one of the most comprehensive options for importing transaction data. The auto-sync via API connections works well for major exchanges, and the platform does a reasonable job of detecting transfers between your own wallets to avoid false taxable events. Tax report generation covers multiple countries, which is a strong differentiator. However, the free tier is quite limited — you can track your portfolio but need a paid plan to actually generate tax reports, and pricing can feel steep for casual investors with smaller portfolios. The platform occasionally struggles with DeFi transactions and complex protocols, requiring manual adjustments. Despite these friction points, Koinly remains one of the best options for crypto tax compliance, especially for users with activity across multiple platforms.
