Employer identification number

What is an employer identification number?

Also called EIN, or federal tax ID.

An employer identification number (EIN) is the federal tax ID that identifies a production company, or a loan-out corporation, to the IRS.

Every production entity needs one to run payroll, and every loan-out and vendor has to provide theirs on a W-9 before accounting can issue payment. A mismatch between the name and EIN on a W-9 triggers IRS backup withholding notices months later, so vendor onboarding checks it up front.

Example

A loan-out corporation submits a W-9 showing a name and EIN that do not match IRS records. Payments go out anyway, and eight months later the production entity, now wound down, receives a backup withholding notice for 24% of everything it paid.

Figures are illustrative, chosen to show the mechanics rather than to quote market rates.

Where you'll see it

Collected on the W-9 at vendor onboarding, before the first payment. Every production entity needs its own to run payroll at all.

Common mistake

Accepting a W-9 without checking the name against the EIN. Mismatches produce IRS notices and backup withholding months later, usually after the entity has wound down.

Related questions

Does a loan-out company need its own EIN?
Yes. The production is engaging a separate corporation, so it needs that corporation's own EIN on a W-9 before any payment is issued.
What happens if a W-9 name and EIN do not match?
The IRS issues a mismatch notice and the payer can become liable for backup withholding on amounts already paid, which is why it is checked at onboarding.
