Best Crypto Tax Software Compared for 2025 Filing
Tax season never ends for crypto traders. Every swap, every airdrop, every liquidity pool deposit can be a taxable event. The right software is the difference between a clean Form 8949 and a headache. Here is how the major platforms compare.
CoinTracker vs koinly: the market leaders
CoinTracker and Koinly dominate the space for good reason. Both support thousands of exchanges and wallets. Both export IRS-ready forms. The differences are in the details.
CoinTracker integrates directly with Coinbase and TurboTax. That direct connection matters if you use either service. It tracks over 20,000 assets. Its DeFi coverage is strong for Ethereum and Solana. But it struggles with lesser-known chains. BSC-based tokens, for example, often require manual import. CoinTracker’s free tier covers up to 3,000 transactions. Beyond that, paid plans start at $14/month for 10,000 transactions.
Koinly supports 20,000+ coins and 700+ exchanges. Its DeFi recognition is broader than CoinTracker’s. It handles L2 solutions like Arbitrum and Optimism natively. Koinly also recognizes NFT sales as capital events - a feature CoinTracker added later and still lags on. The free tier allows up to 10,000 transactions. Paid plans start at $49/year for 10,000 transactions, scaling to $299/year for unlimited.
Where each falls short
CoinTracker’s weakness is complexity. If you use multiple wallets across different chains, manual tagging becomes tedious. Its cost-basis methods are limited to FIFO and LIFO. No HIFO or Specific ID support. That matters if you want to optimize tax lots.
Koinly’s weakness is accuracy on complex DeFi positions. It sometimes mislabels yield farming rewards or pool deposits. Users report needing to manually fix 5-10% of transactions for intricate strategies. Koinly also has no direct TurboTax import - you must download a CSV.
Other Contenders
TokenTax offers the deepest integration for institutional-grade reporting. It supports HIFO and Specific ID. But it costs $199/year for 5,000 transactions. Not for casual users.
CryptoTaxCalculator is a dark horse. It handles BSC and Polygon well. It also recognizes liquidity pool events more reliably than CoinTracker or Koinly. Free tier: 500 transactions. Paid: $99/year for 10,000.
Accointing focuses on simplicity. Good for beginners. Poor for anyone with more than one wallet. Free tier: 1,000 transactions. Paid: $99/year.
Tax-Loss Harvesting Features
CoinTracker offers a “Tax Loss Harvesting” dashboard. It scans your portfolio for unrealized losses. You can batch sell and repurchase within a single interface. Works for spot positions only. Not for DeFi.
Koinly has no dedicated harvesting tool. You must identify losses manually. That is a gap for active traders.
TokenTax includes automated harvesting. So does CryptoTaxCalculator. Both support HIFO, which is the most effective method for minimizing gains.
NFT Support
CoinTracker added NFT recognition in late 2024. It works for Ethereum-based NFTs. Solana and Polygon NFTs often appear as unidentified transfers.
Koinly handles NFTs better. It recognizes sales, purchases, and minting events across Ethereum, Solana, and Polygon. The cost basis for NFTs is tracked individually.
Form Export Quality
Both CoinTracker and Koinly generate IRS Form 8949 and Schedule D. Both produce CSV exports for filing. CoinTracker’s forms are more polished - less manual editing needed. Koinly’s forms sometimes require transaction-level corrections before export.
Free Tier Limitations
None of these tools is truly free for active traders.
- CoinTracker: 3,000 transactions free. No DeFi support on free tier.
- Koinly: 10,000 transactions free. No CSV export on free tier.
- TokenTax: No free tier.
- CryptoTaxCalculator: 500 transactions free.
- Accointing: 1,000 transactions free.
The Bottom Line
CoinTracker is the choice if you use Coinbase and want TurboTax integration. Koinly wins for multi-chain DeFi users who can tolerate manual fixes. TokenTax is for high-volume traders who need HIFO and automated harvesting. CryptoTaxCalculator is the best value for BSC and Polygon users.
No software is perfect. Expect to spend 1-3 hours fixing transaction labels. That is the cost of accurate filing. Choose the tool that minimizes that time for your specific wallet setup.
