If you've ever moved crypto to a personal wallet, your tax form shows missing cost basis. CoinTracker is Coinbase's official tax partner — it reads the on-chain history your broker cannot see.

This is not a glitch. It is a structural gap the new IRS regulations created — and it affects every investor who has ever used a personal wallet.
Completely normal. Recommended, even. But the moment assets left Coinbase, your acquisition history became invisible to your broker.
Not an error. The law mandates they report what they can see. Off-platform wallet history is outside their legal scope. So they report zero.
As Coinbase's official tax partner, it accesses the full on-chain record of every wallet transfer and reconstructs your actual cost basis automatically.
Taxable gain — assumes $0 cost basis
Real gain — cost basis was $12,000
Difference: $2,640 in taxes you should not owe (22% bracket)
The only crypto tax software natively embedded inside Coinbase. Connect once, get your real numbers in minutes.
API access to 500+ exchanges and every major blockchain, including every wallet transfer your broker never recorded.
Traces each asset back to its original acquisition, proving what you actually paid — not what the broker estimated.
Exports directly into TurboTax or H&R Block. One click. No spreadsheets, no manual re-entry, no format errors.
Prime tier identifies every harvestable loss in your portfolio and calculates the exact tax offset before December 31.
Backfile 2021, 2022, and 2023 under one subscription. Competitors charge $49 per tax year — that's $150 for a 3-year backfile.
CoinTracker cannot move or trade your assets. It reads transaction history only. Your private keys never leave your device.

"Without this software, there is NO way I could have figured out all of the transactions across wallets and exchanges. It's bad enough with help from software, but impossible without it."
"The IRS list they sent me was everything they were missing. If you can't match it you'll probably have to put the cost basis as $0. CoinTracker solved that in about 20 minutes."
"It would have been a full-time job just fixing it manually to avoid getting slammed with huge capital gains. CoinTracker found cost basis I thought was gone forever."
Unlike competitors who charge per tax year, one CoinTracker plan covers your complete filing history.
