Client Asks for a W-9 Before Paying: Email Templates to Send It and Get Paid

A W-9 request usually means your invoice is close to being paid: the client's accounts team needs your taxpayer details on file before they can set you up as a vendor. The risk is that the form goes back and forth and the payment date quietly slides. Send it once, send it safely, and ask for the date in the same message.

Before you send your W-9

• Confirm the request is real. If it arrives from an unfamiliar address, check with your usual contact before sending a form that contains your tax ID.
• Use the current form from irs.gov, fill in your legal name exactly as it appears on your invoice payee line, and sign and date it.
• Prefer a secure channel: the client's vendor portal, an encrypted upload link, or a password-protected PDF with the password sent separately. Avoid pasting your SSN or EIN into an email body.
• If you have an EIN, many freelancers use it on vendor forms instead of their SSN.

When to send and what to ask for

• Reply the same day. Every day the form is missing is a day your invoice cannot enter the payment run.
• In the same email, restate the invoice number, amount, and due date, and ask when it will be paid once the form is processed.
• Ask whether they need anything else for vendor setup (ACH form, vendor questionnaire, PO number) so you can send it all at once.
• If two business days pass with no confirmation, follow up once to check the form was received and the invoice is scheduled.

Free template 1: Send the W-9 with the payment details

Replace every [bracket] before sending.

Hi [Client Name],

Thanks for the heads-up. My completed W-9 is [attached as a password-protected PDF / uploaded to your vendor portal / available at this secure link: Link]. [If PDF: I will send the password in a separate message.]

For reference, this is for invoice [Invoice #] for [Amount], due [Due Date]. Once your team has the form on file, could you confirm the date the invoice will be paid?

If vendor setup needs anything else (ACH form, PO number, vendor questionnaire), let me know and I will send it today.

Thanks,
[Your Name]

Free template 2: Check the form was received (2 business days later)

Replace every [bracket] before sending.

Hi [Client Name],

Just checking that my W-9 came through on [Date Sent] and that vendor setup is complete.

Could you confirm invoice [Invoice #] ([Amount]) is now scheduled for payment, and the expected date? If anything on the form needs correcting, tell me and I will turn it around the same day.

Thanks,
[Your Name]

Free template 3: Verify a W-9 request from an unfamiliar sender

Replace every [bracket] before sending.

Hi [Usual Contact Name],

I received a request for my W-9 from [Sender Name / Email] about invoice [Invoice #]. Before I send a form with my tax details, can you confirm that request came from your team and where I should send it?

Once confirmed, I will send it straight away so the invoice ([Amount], due [Due Date]) is not held up.

Thanks,
[Your Name]
