What’s the best crypto tax software in 2025? We compare Koinly, CoinTracker, TokenTax, and TaxAnon — with a focus on DeFi, NFTs, and HMRC/IRS compliance.
🧩 Popular Crypto Tax Tools in 2025
-
Koinly – one of the most popular globally, integrates with 700+ exchanges and wallets.
-
CoinTracker – US-focused, partnered with Coinbase.
-
TokenTax – hybrid model (software + optional accountant support).
-
ZenLedger – simple UI, decent for basic trading records.
👉 These tools are a great starting point — but they’re not perfect.
❌ Limitations of Crypto Tax Software
-
DeFi & NFT Complexity
-
Many tools still can’t categorize yield farming, liquidity pool exits, or NFT minting properly.
-
HMRC/IRS often require manual classification.
-
-
Wrong FX Conversions
-
Crypto-to-crypto trades need fair market value in GBP/USD at the time of trade.
-
Some tools pull inconsistent or missing exchange rates.
-
-
Wallet Transfers = Double Counting
-
Moving ETH from MetaMask → Ledger isn’t taxable.
-
Software often treats it as a disposal, inflating gains.
-
-
Garbage In = Garbage Out
-
If CSVs are messy (and they usually are), the software can’t fix it.
-
Output = incomplete or non-compliant.
-
-
No Professional Liability
-
If the report is wrong, HMRC/IRS won’t accept “the software did it.”
-
The liability is always on you, not the app.
-
✅ Benefits of Done-for-You (Human + Software Hybrid)

-
Compliance Guarantee: Reports structured exactly how HMRC/IRS expect them.
-
48h Turnaround: Faster than waiting for a confused accountant to untangle CSVs manually.

-
Loss Optimization: We ensure all allowable losses are applied correctly — most software misses these.

🔎 Final Thoughts
Crypto tax software is great for simple cases — a few trades, one or two exchanges, no DeFi/NFTs.
But for most traders in 2025, the reality is:
-
Multiple wallets.
-
Dozens of exchanges.
-
Complex DeFi/NFT activity.
👉 That’s where TaxAnon’s hybrid model shines: automation + human review = a report you can actually trust with HMRC, IRS, CRA, or ATO.
