Questions about the W-9 form

Is there a 2026 W-9 form?

The IRS still lists the March 2024 revision as the current Form W-9, and its “Recent developments” says “None at this time.” That is the one to use in 2026, and it is the copy on this page (IRS, About Form W-9, read November 1, 2026). Check the IRS page if you are asked for a newer one.

Is the W-9 form free to fill out here?

Free to start. Your 2 free uses in total need no account. Filling in a form and signing it are free; the file you download counts as one of your free uses. After that, start your 7-day free trial of Pro or buy Pro for $2.99 a month.

Is my information uploaded?

No. The form is filled in your browser and never uploaded, so what you type, including any Social Security number or other tax ID, stays on your device. We do not record what you type.

Is this the latest version of Form W-9?

It is the version the agency listed as current when we last checked on 2026-10-26: Rev. March 2024. We compare our copy with the agency's every week. If the agency updates the form, this page says so and points to the official link until we update ours.

Can I sign the W-9 electronically?

Whether an electronic signature is accepted is up to whoever asked you for the form, unless the agency says otherwise. Check the agency's instructions at https://www.irs.gov/instructions/iw9. PDFinish places a picture of your signature on the page; it is not a certificate-based digital signature.

Where do I send the W-9?

In the agency's words: "Give form to the requester. Do not send to the IRS." (printed on the form) Read the agency's instructions at https://www.irs.gov/instructions/iw9.

What do I put in each box of the W-9?
