Why “Excel” Doesn’t Work

“I’ll just download the CSV file.” Famous last words.
When you move 1 BTC from Coinbase to your Ledger Wallet, the IRS thinks you SOLD it unless you match the transfers perfectly.

Task Manual (Excel) Software
Time Required 40+ Hours 15 Mins
Accuracy Low (Human Error) High (API Sync)
DeFi / NFTs Impossible Supported
Cost $0 (Cost of Sanity) $50 – $200
The “Read-Only” Safety
Paranoid about connecting your wallet? Don’t be. These tools use Read-Only APIs. They can see your transaction history, but they cannot touch or move your funds. It is safe.

Detailed Comparison

1. Koinly (The Reviewer’s Choice)

Koinly is like the “Android” of crypto tax. It gives you tons of control. You can see every transaction and fix errors easily.
Pros: Excellent “Free Preview” (you can see your profit/loss before paying). Great support for weird DeFi protocols.
Cons: The UI is a bit dense for total beginners.

2. CoinTracker (The “Apple” Choice)

If you use Coinbase, you’ve seen this. They partner with big exchanges. It is beautiful and simple.
Pros: Seamless integration. The mobile app is a great portfolio tracker.
Cons: Expensive. If you have a lot of transactions, the price jumps to $199+ very quickly.

3. TokenTax (The “White Glove” Service)

Do you have millions in crypto? TokenTax isn’t just software; they have actual CPAs who check your file.
Verdict: Overkill for most, but essential for whales.

Pro Tip: Harvest Your Losses

The software isn’t just for paying taxes; it’s for saving taxes.

The Dashboard Check

Log into Koinly/CoinTracker in December.
Look for the “Unrealized Losses” column. If you see a coin down 90%, sell it before Dec 31st to lock in that loss. The software will calculate exactly how much tax you save.
(Note: It pays for the software subscription instantly).

Frequently Asked Questions

Does the IRS really know?
YES. Centralized exchanges (Coinbase, Kraken) are required to send Form 1099-DA to the IRS. If your tax return doesn’t match their data, you get an audit letter.
What about NFTs?
NFTs are taxed as property (capital gains). Most software now detects OpenSea transactions automatically, but you might need to manually tag the “Gas Fees” as costs.
