Employers can complete the following forms within this Component:
- Identity verification (liveness check)
- IRS Form 8655
- Any required state authorization form that allows Check to file and remit taxes on the employer's behalf
Identity verification
Before signing their filing authorization forms, employers complete a liveness check - they validate a government-issued ID against a real-time facial capture. This appears as the first step in the Component for companies where liveness checks are enabled, which covers most partners.
No integration changes are required. The Component URL returned by this endpoint automatically presents the right flow for each company, and completion states and webhook behavior are the same whether or not the liveness step is shown.
For more on how liveness checks work, see our Help Center article.
To learn how to add this Component to your application, see our embedding guide.
Liveness checks are enabled for most partners. If you're not sure whether they're enabled for your account, reach out to your Check contact.
