What is a W-9 form?
Form W-9 is used to provide your taxpayer identification number to a business or individual who will pay you as a contractor or freelancer. If a client asked you to "fill out a W-9 online," you can upload the PDF they sent you, type in your name, address, and taxpayer ID, and download the completed form to send back — no printing, signing by hand, or scanning required.

What information goes on a W-9
A standard W-9 asks for your full legal name, your business name if it's different, your federal tax classification (individual, sole proprietor, LLC, corporation, partnership, and so on), your address, and your Social Security number or Employer Identification Number. Most freelancers and contractors fill out a W-9 once per client relationship, so getting the details right the first time means you usually won't need to touch it again until something changes, like a new address or a change in business structure.
Why clients ask for a W-9
If a business pays you $600 or more in a year as a non-employee, they're required to report that payment to the IRS on a 1099, and they need your taxpayer ID to do it. That's why a new client almost always asks you to fill out a W-9 online before they send your first payment. Sending it back as a properly filled PDF — rather than a photo of a handwritten form — looks more professional and avoids back-and-forth over illegible handwriting.
Filling out a W-9 without special software
You don't need Adobe Acrobat, a printer, or a scanner to fill out a W-9 online free. Many W-9 PDFs that clients send out aren't proper fillable forms — they're flat scans or simple templates — which is exactly the case our auto-detection is built to handle. The tool finds the labeled blanks on the page and turns them into editable fields, so you can complete the entire W9 form fill out online process in your browser in a couple of minutes.
