The crypto tax software market has matured significantly, but choosing the wrong tool can cost you hours of manual corrections and, in some cases, incorrect tax filings. We evaluated six major platforms on the criteria that actually matter: accuracy of cost basis calculation, exchange support, ease of use, DeFi handling, and pricing. Here's what we found.
What to Look for in Crypto Tax Software
Before diving into specific tools, here are the criteria that separate good crypto tax software from mediocre options:
- Exchange integrations — Does it support all the exchanges and wallets you use?
- Cost basis accuracy — Does it correctly handle transfers between wallets, DeFi, and edge cases?
- Accounting methods — Does it support FIFO, LIFO, HIFO, and specific identification?
- Per-wallet tracking — Does it comply with new 2025 IRS requirements?
- DeFi support — Does it handle swaps, liquidity pools, staking?
- Tax report quality — Are the generated reports accurate and accepted by the IRS?
- Price — What do you get for what you pay?

TaxBit

TaxBit started as an enterprise solution for crypto exchanges and has expanded to individual users. Their accuracy is excellent for standard transactions, and they have strong IRS reporting compliance. However, it's priced for serious traders.

Limitations:
- Expensive ($175+/year)
- Complex UI for beginners

How to Choose: Questions to Ask Yourself
- How many transactions do you have? Under 100 → most tools work. Over 1,000 → look carefully at pricing tiers.
- Do you use DeFi? DeFi handling varies wildly. BasisTracker and Koinly handle it reasonably well; CoinTracker struggles.
- Do you value privacy? BasisTracker is the only major desktop option — your data never leaves your machine.
- What exchanges do you use? Verify specific exchange support before committing.
- Do you want a subscription or one-time payment? Most web tools are subscriptions. BasisTracker offers a one-time pricing model.

Conclusion
There's no single "best" crypto tax software — the right choice depends on your transaction volume, exchange mix, DeFi activity, and privacy preferences. What hasn't changed is the need for accurate records. Any of these tools is better than trying to track hundreds of transactions manually in a spreadsheet.
Our recommendation: start with BasisTracker if you're a US-based investor who values privacy and wants a local tool. If you need extensive multi-country support or have deep DeFi history, evaluate Koinly or TaxBit depending on budget.
