If your Robinhood 1099-DA shows proceeds that look too high, transferred crypto with incomplete history, or missing cost basis, your taxable gain may be overstated. This Robinhood mismatch checker helps you spot warning signs before you file or send records to a tax preparer.
Robinhood may report crypto sales based on records available inside the platform. If you bought assets elsewhere and later transferred them in, the form may not reflect your full acquisition history. That can make gains appear higher than they should be.

A common issue happens when crypto is bought on another exchange, transferred into Robinhood later, and then sold on Robinhood. In that case, Robinhood may report the sale proceeds while showing limited acquisition history inside the platform. If the original cost basis does not carry over fully, the reported gain can look higher than it should.
1. Why does my Robinhood 1099-DA show proceeds but not a clear cost basis?
Robinhood may only report the data available inside the platform. If crypto was transferred in or originally purchased elsewhere, the full basis history may not appear automatically.2. Can transferred crypto make my Robinhood gains look too high?
Yes. If the original buy records are missing or incomplete, reported proceeds may be compared against too little basis, which can overstate gains.3. Should I reconcile Robinhood crypto records before filing?
If your records include transferred assets, outside purchases, or missing acquisition history, reconciliation is strongly recommended before filing.4. What does this checker actually review?
