W-9

What is a W-9?

Also called W9, or taxpayer identification request.

A W-9 is the form on which a vendor, loan-out corporation, or independent contractor certifies its legal name, entity type, and taxpayer identification number so the production can report payments correctly.

No vendor should be paid without one on file, because the production is responsible for 1099 reporting and for backup withholding if the details are missing or mismatched. Name and EIN mismatches generate IRS notices months later, typically after the entity has wrapped.

Example

A vendor's W-9 shows a trading name while the EIN belongs to the registered company. Payments go out, and months later the production receives an IRS notice and a backup withholding obligation on everything it paid that vendor.

Where you'll see it

Collected at vendor onboarding, before the first payment. The basis of the production's 1099 reporting.

Common mistake

Accepting a trading name that does not match the EIN. The mismatch produces an IRS notice and a backup withholding obligation months later.

Related questions

Why does a production need a W-9 from a vendor?
To certify the vendor's legal name, entity type, and taxpayer identification number, so the production can report payments and avoid backup withholding.
Can a vendor be paid without a W-9?
It should not be. The production carries the 1099 reporting obligation and the backup withholding exposure if the details are missing or wrong.
