Do I need to install any software to use Formize’s PDF filler?

No. Formize runs completely in your web browser on a secure HTTPS connection. No downloads or plugins are required.

Is the information I enter into the W-9 kept private?

Yes. All data stays in your browser session and is only transmitted when you choose to download or email the completed PDF.

Can I save my progress and finish the form later?

Formize does not store your data on its servers, so you’ll need to download the partially‑filled PDF and re‑upload it later if you want to continue.

What if I make a mistake after I’ve signed?

You can clear the signature field, correct the mistake, and re‑sign. The form will automatically update.

Is the fillable W-9 PDF from Formize officially accepted by the IRS?

Yes. The PDF is the exact same document as the official IRS version (fw9.pdf). Using a fillable version does not change its legal validity.

Can I use the completed W‑9 for multiple payers?

You can reuse the same information, but each payer may require a newly signed form. It’s best to generate a fresh copy for each request.
