CryptoTax DeFi vs Koinly: Which Crypto Tax Tool Is Better for DeFi?

Why This Comparison Matters

Koinly is one of the most popular crypto tax tools on the market, with support for hundreds of exchanges and a polished user experience. But when it comes to DeFi accuracy and user privacy, there are meaningful differences. This comparison helps you decide which tool fits your needs.

DeFi Accuracy

CryptoTax DeFi: Built specifically for DeFi from the ground up. Uniswap v3 concentrated liquidity positions are tracked individually by NFT position ID. Bridge transfers are automatically detected as non-taxable self-transfers. Staking rewards from protocols like Lido and Rocket Pool are categorized as income events at the correct fair market value.

Koinly: Supports basic DeFi transaction import but relies heavily on manual categorization for complex DeFi interactions. Uniswap v3 LP positions may be misclassified as simple swaps. Bridge transactions often appear as unknown transfers that require manual tagging. Staking reward detection works for major protocols but misses many smaller ones.

Verdict: If you are a DeFi-heavy user with LP positions, cross-chain activity, and protocol interactions, CryptoTax DeFi provides significantly more accurate automatic categorization.

Privacy and Data Handling

CryptoTax DeFi: All calculations run locally on your device. Your wallet addresses, transaction history, and financial data never leave your machine. There is no cloud storage, no server-side processing, and no database of your information to breach.

Koinly: Your data is uploaded to Koinly's cloud servers for processing. This includes your wallet addresses, full transaction history, and calculated gains and losses. Koinly states they use encryption and security best practices, but your data does live on their infrastructure.

Verdict: If privacy is a priority, CryptoTax DeFi's local-first approach is fundamentally more secure. There is no data to breach because there is no centralized database.

Pricing

CryptoTax DeFi:

• Free: 100 transactions, 1 wallet
• Pro: $9.99/month for 5,000 transactions, 5 wallets, all chains

Our Honest Take

Koinly is a solid product that works well for exchange-heavy traders. But if DeFi is a significant part of your crypto activity, Koinly's categorization limitations can lead to incorrect tax calculations, particularly for LP positions and bridge transfers. CryptoTax DeFi was built to solve exactly that problem, with the added benefit of never sending your data to an external server.
