IRS form W-9

Collect and fill Form W-9 for every vendor and client

Form W-9 is how a business gets a payee's correct name and taxpayer identification number (TIN) for the information returns it files, such as Forms 1099-NEC and 1099-MISC. It doesn't go to the IRS: whoever asked for it keeps it on file. With BoltPDF you collect W-9s from every vendor through one link, or fill them for all your clients at once.

Form
Form W-9: Request for Taxpayer Identification Number and Certification
Issued by
Internal Revenue Service (United States)
Who uses it
Contractors, vendors and other US payees fill it for the businesses that pay them. Bookkeepers collect it before 1099 season, and firms fill it for clients who are asked for one.

What’s on Form W-9

The March 2024 revision of the form asks for:

Upload the W-9 once and BoltPDF finds its fields. Then make a share link that asks for a signature and send it to your vendors, or put it on your website. Each vendor fills in their name, classification, address and TIN, confirms their email and signs. Every submission becomes a record in BoltPDF with the signed PDF and its audit trail, so the TINs you need for 1099s are already typed in, not sitting in a stack of scans.

Fill W-9s for all your clients at once

When your clients are the ones being asked for a W-9, keep each client’s details as a record. BoltPDF fields share standard names, so the name, EIN and address you enter once also fill Form 8821, Form 2848 and any other form that asks for them. To do a whole client list, import a CSV with one row per client and download every filled W-9 in one ZIP.

Keep TINs out of reach

A W-9 carries a full SSN or EIN. In the records spreadsheet, SSN and EIN columns show only their last four digits until someone chooses to show them, and each record keeps a log of who viewed or changed it. If you need to pass a W-9 on with the TIN blacked out, redact it in BoltPDF first. It happens in your browser, and the TIN is taken out of the file, not just covered.

Questions about Form W-9

Do I send Form W-9 to the IRS?

No. The business that requested it keeps it and uses the name and TIN on the information returns it files, such as Form 1099-NEC. The IRS gets the 1099, not the W-9.

Can vendors fill out and sign a W-9 online?

Yes. Send a BoltPDF share link that asks for a signature. Each vendor fills in the form, confirms their email with a code, and signs; you get the signed PDF with a record of who signed and when. The IRS's Instructions for the Requester of Form W-9 list what an electronic W-9 system has to do, so check them against your process.

How do I get W-9s from 50 vendors at once?

Share one link with all of them, or, for vendors already saved as records, send a client request to up to 50 records in one go. Requests can have a due date, and BoltPDF emails reminders to anyone who hasn't answered.

Can I fill W-9s for many clients from a spreadsheet?

Yes. Import a CSV with one row per client and BoltPDF fills a W-9 for each row, downloaded together as one ZIP.
