Check your SSN or EIN before you sign
A wrong digit in Part I is the most common W-9 mistake. This checks the number's format against IRS and SSA rules — on this device only, nothing is sent or saved.
Type the 9 digits; dashes are optional.
A format check can't confirm the number is yours or matches IRS records — only that it could be a real number.

Who gets a W-9?
Form W-9 goes to the business that will pay you — not to the IRS. They use it to issue your 1099. Many requesters accept a signed PDF; if they have their own secure portal, use that instead of email.
Only send a W-9 to someone you're actually doing business with. Unexpected W-9 requests by email are a common identity-theft scam.
W-9 questions
Do I have to sign a W-9?+
For many payments, such as freelance fees, the IRS only requires your signature if you were told your number was wrong before — but almost every business asks for a signed W-9, and it must be signed for interest, dividends and real estate transactions. See our line-by-line guide.
Is an electronic signature OK on a W-9?+
The IRS allows requesters to accept electronic W-9s. Most accept a signed PDF; check with yours if unsure.
Is it safe to type my SSN here?+
The form is processed only in your browser. We never receive your file or your number.
What does it cost?+
Free to try. Downloading your signed PDF costs €2.99 a month or €24.99 a year, and you can cancel anytime.
