Free W-9 Form Filler

Yes, completely free with no account or sign-up required, and no limit on how many you fill out.

No, and this matters more here than on any of our other free tools. The PDF is filled in entirely inside your own browser — your name, address, and SSN or EIN are never transmitted anywhere, not even to SignFastAi. You can disconnect from the internet after the page loads and the tool still works.

Yes. This tool fills in the actual current IRS Form W-9 (Rev. March 2024) PDF, not a lookalike — the fields line up exactly with what a requester (like a client paying you as a contractor) expects to receive.

No. The official W-9 itself leaves "Signature of U.S. person" and "Date" as a blank line, not a fillable field — you still need to sign it. You're welcome to print and sign it by hand, or upload the PDF this tool downloads straight into SignFastAi to sign it electronically.

Most individuals and sole proprietors enter their Social Security Number. If you have an Employer Identification Number for a business entity, use that instead — enter one or the other, not both. If you're unsure, the IRS's own W-9 instructions (linked on the form itself) cover this in more detail.

This page just fills in and downloads a W-9 PDF for you to send however you like. SignFastAi's core product lets you upload any document, place signature fields on it, and send a secure signing link to get it actually signed online.
