What to watch for on a Coinbase 1099-DA

The Coinbase details that trip up a clean Excel / Google Sheets filing — and how the converter handles each.

Note 01

Coinbase issues a 1099-DA for your 2025 disposals, but TurboTax can't import the PDF — TXF is the format TurboTax Desktop still accepts.

Note 02

Lots held from before 2025, transferred in from a wallet, or moved through Coinbase Wallet come back marked Unknown cost basis.

Note 03

Import the 1099-DA as-is and Unknown lots are taxed at zero basis — reconciling against the Coinbase Gain/Loss report fixes that.

Coinbase to Excel / Google Sheets FAQ

Where do I get my Coinbase 1099-DA?

Download the Coinbase 1099-DA PDF from Taxes → Documents. If it shows Unknown cost basis, also grab your Coinbase Gain/Loss report so the reconciler can fill in the missing numbers.

What exactly do I download?

A Form 8949 CSV — one row per disposal with description, acquisition and sale dates, proceeds, cost basis, gain/loss, and any wash sale adjustment. Open it in Excel or Google Sheets, or hand it to your CPA.

Why does my Coinbase 1099-DA show Unknown cost basis?

Crypto broker basis reporting wasn't required before January 1, 2025, so lots held from before then often report Unknown — as do coins transferred in from a wallet or another exchange. Upload your Coinbase Gain/Loss report and the reconciler fills the basis in before writing the CSV.

Are wash sales handled?

If your 1099-DA includes wash sale figures, they pass through using the standard crypto codes (322 short-term, 324 long-term). The IRS has not formally extended the wash sale rule to digital assets for the 2025 filing year, so we honor whatever your source reports rather than inferring new adjustments.

Is my file stored anywhere?

No. Your upload is processed in memory and deleted when the conversion finishes. The output bundle stays available for 24 hours, then is removed. There's no account to create.

I just want a clean spreadsheet from my Coinbase 1099-DA — can I get that?

Yes. Choose the Excel / Google Sheets option and you get a Form 8949 CSV — one row per disposal with dates, proceeds, cost basis, gain/loss, and wash sale — after reconciling any Unknown basis against your Coinbase Gain/Loss report. It's ready for your own worksheet or a CPA hand-off.
