Let me tell you my personal experience of why I stopped using just one Tax tool for crypto.
In 2024, I had over 600 DeFi transactions, three active wallets, and income from staking, airdrops, NFT royalties, and validator rewards.
I used one of the “top 3” crypto tax platforms.
Guess what happened?
- 70+ transactions went uncategorized
- My gas fees were misclassified
- My airdrops were taxed wrong
- And worse, cross-chain swaps were treated as non-taxable, even though the IRS sees them otherwise
That tax return almost got flagged.
That is when I discovered a method no one talks about: Combining multiple crypto tax software together.
2025 Crypto Tax Software at a Glance
Most tools miss edge cases. Combining platforms gives you better tax accuracy, smarter tracking, and peace of mind. The IRS doesn’t care which app you use; instead, you are responsible for reporting it correctly. Read on to see how to do it better than 95% of traders.
Why One Platform Isn’t Enough Anymore for Crypto Tax?
Let’s be clear: tools like Koinly, CoinTracker, Accointing, and TokenTax are excellent, but none are complete.
Why?
| Limitation | How It Hurts You | Use case |
| Misses’ certain chains | You underreport or misreport | zkSync or Base network transactions not captured |
| Doesn’t track NFT royalties correctly | You overpay taxes or miss write-offs | Lazy Minting sales misclassified |
| Poor CSV handling | Data import fails or duplicates | Wallets using Rainbow or Argent |
| Weak smart contract support | Loss of yield data | Rebase tokens or wrapped LP tokens untracked |
That is why power users and pros are now blending tools, and when done correctly, it is 100% IRS-safe.
So, let’s talk about the method to combine multi-crypto tax tools safely.
Combining multiple crypto tax software together?
Follow the steps to Combine multi–Crypto Tax software (as per my experience, it is the safest method)
Step 1: Use Koinly or CoinTracker as your base platform
- These support API + CSV + exchange integration
- Auto-detect staking, NFTs, farming income
- Good UI for review
But here is the twist
Step 2: Use Accointing for wallet-specific DeFi or NFT edge
- Tracks multi-chain DeFi more reliably
- Strong CSV import matching
- Better control over wallet syncing manually
My tip: I use Accointing only for Layer 2s and NFT-heavy wallets, then manually export to merge.
Step 3: Use Token Tax for Final Accuracy + Tax Form Filing
- Offers real CPA audits
- Let you upload merged data
- Fixes cost basis, wrapped tokens, LP positions
How I Sync Everything Together for crypto tax?
Let me share my strategy to combine crypto tax software with you. First,
| Data Type | Tool Used | What I Do |
| Layer 1 tokens (ETH, BTC, SOL) | Koinly | Sync API + tag rewards manually |
| DeFi (Aave, Yearn, Curve) | Accointing | Export CSV and validate gas fees |
| NFTs | Accointing + TokenTax | Track mint-to-sale flow manually |
| Layer 2 (Arbitrum, zkSync) | Accointing | Tag bridge transfers clearly |
| Final Report | TokenTax | Reconcile all CSVs + match with 8949 |
Then, I manually create a master CSV that Token Tax can finalize.
The result?
1. Precise gain/loss reports
2. Correct staking/taxable income reporting
2. Peace of mind during IRS season
Why do 3 Tools greater than 1 Tool?
Let me share with you a client story:
In 2024, a client had:
- 4 wallets (ETH, Polygon, Base, Solana)
- Income from YouTube tips (in crypto)
- NFT royalties (3 different collections)
We used:
- CoinTracker for ETH + staking income
- Accointing for NFT logs + Solana
- TokenTax for Form 8949 + Form 8275 (for disputed staking logic)
Final result:
We uncovered $4,322 in missed losses and avoided a $1,700 tax overpayment.
When to Use Which Crypto Tax Tool?
Copy my techniques if you are in a similar situation to me.
| Tool | Best For | Weakness | Use In This Stack |
| Koinly | Clean Layer 1 wallets, staking, 1099-B import | Struggles with L2 DeFi | Start here |
| CoinTracker | Multichain basics, portfolio tracking | NFT royalty data weak | Swap with Koinly optionally |
| Accointing | DeFi, gas-heavy chains, manual tagging | Interface less intuitive | Use for L2 + NFT |
| TokenTax | Final tax forms, CPA review | Expensive tiered pricing | Use to close + file with IRS |

My Professional Tips for Crypto Tax Software?
These are my advice from personal experience. So don’t forget to thank me in the comments section if you benefited.
- Tag your transactions instead of trusting automation; especially LP adds/removes.
- Always use UTC timestamps across platforms.
- Keep PDFs of export logs. Why? IRS may ask for “proof of gain/loss method.”
- Run two tools in parallel for Q3–Q4 as a dry test.
- If a token is rebased (OHM forks), check if your platform auto-adjusts cost basis.
Key Takeaways (Bookmark This Now)
- No single platform handles all wallets, all chains, and all types of income.
- Koinly is best for clean Layer 1 income + staking rewards.
- Accointing handles NFT + gas fee-heavy chains better.
- TokenTax provides CPA-compliant output and IRS documentation tools.
- Combining platforms helps catch underreported or misclassified activity.
- Final merged CSV + Form 8275 can shield you from penalties.
- Manual tagging matters more than automation, especially gas fees, rebates, and bridge moves.
- Bookmark your reconciliation files because the IRS may question you 1–3 years later.

Concluding Thought
So, should you combine crypto tax tools? Yes, with following conditions.
| If you | Then… |
| Are a casual trader with only 1 wallet | Use Koinly or CoinTracker solo |
| Use DeFi, NFTs, and multiple chains | Combine Koinly + Accointing + TokenTax |
| Are earning staking/yield across protocols | Manually tag rewards across tools |
| Want CPA-grade documentation | Use TokenTax for final report |
| Plan to scale in 2025 | Start tracking each wallet + CSV today |
My final advice: Relying on one platform is like filing fiat taxes with only your PayPal history & it is dangerous. Combine smart. Audit early. File confidently.
Frequently Asked Questions (FAQ) about combining multiple crypto tax software?
Is combining tools legal with the IRS?
Yes. The IRS cares about accurate reporting, not which tool you use, as long as the trail is documented.
Will combining multiple crypto tax tools cost more?
Maybe. But $49–$150 in software costs can easily save you $1,000+ in tax accuracy or penalties.
Should I use an accountant, too, for crypto tax?
Only if your return is complex or over $25k in gains. But this method still gives you 90% of the cleanup before a CPA touches it.
How do I merge CSVs for crypto tax tools?
You can merge CSVs by using Google Sheets or Excel. Use consistent column headers to align wallet names, timezones, and amounts.
