Form 1099-DA export format

reference — converter in development

This is the format reference for Form 1099-DA PDF — where the file comes from, what each column means, and the export quirks that matter. The converter for this format is still in development; the reference below documents the layout itself.

Layout evidence: Box layout per the official IRS form (irs.gov f1099da.pdf), documented in research/parser-fixture-validation-2026-10.md — issuer PDFs are custom-styled.

How to export the file

Open your broker’s tax center — Coinbase → Statements, Kraken → Documents, Gemini → Tax Documents, etc.
Download the Form 1099-DA PDF for the tax year — the full form, not an activity summary.
Keep the PDF as issued — do not print-to-PDF or copy tables into a spreadsheet (layout is what extraction reads).

Column reference

IRS Form 1099-DA (2025) — box layout

The federal box order is fixed; each issuer renders it in its own styled PDF.

Column	What it means
`Box 1a`	Digital-asset code.
`Box 1b`	Name/description of the digital asset.
`Box 1c`	Units sold or disposed.
`Box 1d`	Date acquired.
`Box 1e`	Date sold or disposed.
`Box 1f`	Gross proceeds.
`Box 1g`	Cost or other basis.
`Box 1h`	Accrued market discount.
`Box 1i`	Wash-sale loss disallowed.
`Box 2`	Whether basis was reported to the IRS.
`Box 3a`	Gross vs net proceeds election.
`Box 3b`	QOF (qualified opportunity fund) indicator.
`Box 4`	Federal income tax withheld.
`Box 5`	Loss not allowed indicator.
`Box 6`	Short-term / long-term indicator.
`Box 7`	Cash-only (noncash) indicator.
`Box 11a/11b`	Aggregate reporting indicators.

Format quirks

For 2025 sales, custodial brokers report gross proceeds only — mandatory basis reporting on covered assets starts with the 2026 forms. A missing basis column is normal, not a redaction.
Every issuer styles the form differently — the IRS box order is fixed but the PDF layout is per-issuer, which is why extraction is adapter-by-adapter.
Boxes 6/7/11 decide how rows map onto Form 8949 categories (short/long term, cash-only, aggregate) — the same split your tax software applies.
Unlike the CSV tools on this site, PDF extraction is planned as a server-side step — the format reference is real today; the converter pages stay marked planned until the extractor ships.

⚠ Extraction adapters are in development (NEEDS-SERVER) — this page documents the form itself, verified against the official IRS layout.
