FAQ

Is there a w-2 parsing API?

Yes. W-2 Parser exposes a REST endpoint — POST a w-2 file to /api/extract with your API key and receive structured JSON. No SDK required; it is a standard multipart upload.

How is the w-2 API priced?

By document, not per page. Free includes 3 w-2s; paid plans run from $9/mo (20 docs) to $199/mo (1,000 docs) with full API access on every tier. No per-page surprises and no enterprise minimums.

What does the API return?

A JSON object with the extracted fields (Wages, tips, other comp (Box 1), Federal income tax withheld (Box 2), Social Security wages & tax (Boxes 3-4), and more) plus a per-field confidence score. You can also request CSV/Excel exports.

How do I get an API key?

Sign up (free, no credit card), open your dashboard, and copy your key. You can start calling the API within a minute.

Can I process w-2s in batch?

Yes. Use the batch and async endpoints to submit many w-2s at once and poll for results — ideal for high-volume automation.
