Coinbase 1099-DA to TurboTax

TurboTax can't read the Coinbase 1099-DA PDF directly, and TurboTax Online dropped crypto CSV import in January 2026. The reliable path is TXF: upload the Coinbase 1099-DA here, reconcile any Unknown basis against your Coinbase Gain/Loss report, download the TXF, then in TurboTax Desktop go to File → Import → From Accounting Software → Other Financial Software (TXF) and select the file. On TurboTax Online, use the Form 8949 CSV/XLSX from the bundle for manual entry.

In Coinbase, open the profile menu and go to Taxes → Documents (on the web, it's under Reports/Documents in the Taxes section). The crypto 1099-DA is listed there once Coinbase generates it, usually between mid-February and early March of the year after the tax year. Coinbase also emails you when tax documents are ready.

Crypto broker basis reporting wasn't required by the IRS until January 1, 2025, so lots you held on Coinbase from before that date often report Unknown. Anything transferred in from an external wallet, another exchange, or self-custody Coinbase Wallet also shows Unknown, because Coinbase never saw the original purchase. Upload your Coinbase Gain/Loss report or the source transaction history and the reconciler fills the basis in.

The Coinbase Gain/Loss report is a CSV Coinbase generates in the Taxes section that lists each disposal with proceeds and, where Coinbase has it, cost basis. It's the cleanest source for reconciling Unknown lots on your 1099-DA — the reconciler matches each Unknown disposal to the corresponding Gain/Loss row. You only need it if your 1099-DA has Unknown basis; if every lot already has basis, the PDF alone is enough.

Coinbase Wallet is self-custody and separate from the Coinbase exchange, so moving a lot between them breaks the basis chain the same way an external transfer does — the receiving side reports Unknown. Upload the transaction history that covers the original purchase (a Coinbase Gain/Loss report, a Coinbase Wallet export via Etherscan, or an exchange CSV) alongside the 1099-DA and we bridge the basis by matching ticker, quantity, and date.

If the 1099-DA flags wash sales, the values pass through to the TXF using the standard codes (322 short-term wash, 324 long-term wash). The IRS hasn't formally extended the wash sale rule to crypto as of the 2025 filing year, but Coinbase may still report figures on the 1099-DA — we honor whatever the form says rather than overriding it.

Desktop only for the TXF. TurboTax Online doesn't accept TXF imports from any source. If you're filing with TurboTax Online, either switch this filing to TurboTax Desktop or use the Form 8949 CSV and XLSX we provide for manual entry — the import guide PDF walks through the screens either way.

No. The PDF and any CSV are processed in memory and deleted when the conversion finishes. The output bundle stays available for 24 hours behind a signed URL, then is removed. We don't keep your tax documents and there's no account to create.
