We tested the major crypto tax platforms so you don't have to. Here's the honest breakdown of what works, what doesn't, and what might cost you more than you think.
How We Tested
We tested each platform with:
- Multi-chain portfolios (Ethereum, Solana, Bitcoin)
- DeFi transactions (swaps, staking, liquidity)
- NFT purchases and sales
- Cross-chain bridges
- Accuracy of cost basis calculations

What Nobody Tells You
The Hidden Costs
- Per-chain fees — Most tools charge extra for each blockchain
- Transaction limits — Free tiers cap at 100-500 transactions
- API credits — Some charge per API sync
- Hidden "premium" features — 1099-DA often costs extra
The Bridge Problem
Most crypto tax software incorrectly taxes bridge transactions. When you bridge ETH from Ethereum to Arbitrum, many tools count it as:
- Selling ETH on Ethereum (taxable)
- Buying ETH on Arbitrum (taxable)
This is wrong. Bridging your own assets between chains is a non-taxable transfer. Arthur Labs is one of the few tools that detects and handles this correctly.
Our Recommendation
- Simple portfolio (2-3 chains, mainly exchanges): CoinTracker or Koinly
- Heavy DeFi user: Arthur Labs (better bridge/DeFi handling)
- NFT trader: TokenTax or Arthur Labs
- Budget-conscious: Arthur Labs ($7.50/wallet vs $49+)
