Monitor TINs for newly formed businesses

TINs for newly formed businesses may take up to two weeks to appear in the IRS database. As a result, initial TIN verification through Middesk may fail, even if the business information is correct.

TINs associated with new businesses are sometimes unverifiable, yielding an unknown status when initially verified through Middesk’s TIN Match. This is due to a data lag in the IRS’s TIN matching program. When a TIN returns an unknown status, it’s typical to request documentation from the business.

Middesk’s TIN Discovery feature provides an alternative approach that seamlessly attempts to re-verify a business’s TIN without further friction imposed on the customer. If a TIN is not found and the business was formed within the last 30 days, Middesk continues verification attempts for up to two weeks after the initial attempt. With TIN Discovery, Middesk attempts to verify the businesses TIN multiple times, at 1, 3, 7 and 14 days after the business is subscribed to monitoring.

TIN Discovery lifecycle

Here’s the typical lifecycle of TIN Discovery:

1. A business gets created with the POST /businesses endpoint.

2. The business is subscribed to TIN monitoring.
3. A TIN verification is attempted at 1, 3, 7 and 14 days after subscribed.
4. A webhook event is sent to registered webhook endpoint(s) if a new TIN status is found.
5. The client application ingests and evaluates the change in the business record.

Middesk runs checks on a set cadence for 2 weeks to find TINs for businesses whose TINs were previously unknown.

Using webhooks, watch for tin.retried events to receive updates whenever a discovery attempt is made.
