What is Form W-9?

Form W-9, Request for Taxpayer Identification Number and Certification, is the IRS form a business uses to collect a contractor's or vendor's legal name, tax classification, address and taxpayer ID. The payer uses it to file information returns such as Form 1099-NEC or 1099-MISC.

Who needs to fill out a W-9?

Independent contractors, freelancers, consultants, sole proprietors, LLCs and other U.S. businesses fill out a W-9 when a client or payer asks for one. Banks and brokers may also ask for it when you open an account.

How to fill out Form W-9?

Form W-9 Preview

1. Open the W-9 in the Profi PDF editor. The blank IRS form is already loaded.

2. Line 1: enter your name exactly as it appears on your tax return. For a disregarded LLC, enter the owner's name.

3. Line 2: enter your business name or DBA if it differs from line 1. Otherwise leave it blank.

4. Line 3a: check one tax classification box. Check line 3b only if it applies to your partnership, trust or estate.

5. Line 4: enter exemption codes if you have them. Most individuals leave it blank.

6. Lines 5 and 6: enter the mailing address where the payer should send your 1099.

7. Part I: enter your SSN or EIN.

8. Part II: sign and date the form with the signature tool.

9. Download the PDF and send it to the person who asked for it.

Where do I send my completed W-9?

Send it to the business or person who asked for it, not to the IRS. The form carries your SSN or EIN, so use the requester's secure portal or another safe channel instead of plain email when you can.

When is a W-9 due?

The IRS sets no deadline. Send it when the payer asks, usually before your first invoice is paid. A late W-9 can hold up your payment or lead to backup withholding.

When is a W-9 not required?

Employees don't fill out a W-9: they give their employer a W-4 and get a W-2. Foreign persons use Form W-8BEN (individuals) or W-8BEN-E (entities) instead.

How do I sign a W-9 online?

After you fill in the form, click the signature tool, draw, type or upload your signature, and place it in Part II. Most requesters accept an e-signed W-9. If yours asks for ink, download the form, print it and sign by hand.

Is this the current W-9 for 2026?

The editor has the Rev. March 2024 W-9, the revision the IRS issued in March 2024. Before you send it, you can confirm on irs.gov that no newer revision has been released.
