your 1099-DA form: what to export, and what the numbers leave out
Getting your your 1099-DA form history out takes about thirty seconds. Making it produce a defensible tax number takes more, because every platform loses something on the way — and the parts it loses are the parts your tax authority never sees either. Here is exactly what we read from this export, what routinely breaks, and what a free scan shows you before you pay anything.
Export your your 1099-DA form history
- Open our 2-minute 1099-DA CSV template
- Copy the boxes from the form into it — one row per line on the form
- Drop it into the free scan
Drop the file straight into the free scan — the format is detected automatically, nothing is uploaded to a third party, and unsaved scans delete themselves after seven days.
What happens when you drop it in
The format is fingerprinted from its own column headers, every row becomes a ledger entry with the source row cited beside it, and lots are rebuilt wallet by wallet. Rows we cannot price defensibly are listed as skipped with the reason — never booked at zero and never averaged away.
What breaks on your 1099-DA form
These are not hypotheticals: each one is a case our own importer handles or deliberately refuses to guess at.
The form is the fastest way to see the problem: with nothing but your 1099-DA we can show what it overstates before you gather a single exchange export.
Blank or zero basis lines are the whole story. Each one asks the IRS computer to treat the entire sale price as profit, and each one is fixable with evidence you already have.
Wash-sale and box codes change the treatment of a row; we read them rather than averaging everything into one number.
What the reporting leaves out
Brokers report what they can see. Every coin that arrived from another platform or a wallet is, by construction, unpriced on the form.
The number you correct is not the broker's error — it is the gap between what they can know and what you can prove.
This importer is drafted from your 1099-DA form's documented export format and is locked against real exports as customers supply them. Where a row does not match what we expect, the scan says so instead of quietly dropping it.
