An employer identification number (EIN) is a tax identification number used by businesses and other entities. EIN holders are required by regulation to update responsible party information with the IRS. The IRS should be notified within 60 days of certain changes.

The IRS points out this requirement is a key security issue. If data on file with the IRS is outdated or incorrect, this jeopardizes the IRS’s ability to quickly contact the business in case of identity theft.

EIN holders should use Form 8822-B, Change of Address or Responsible Party-Business to provide updated information about the entity’s responsible party or business location.

Individuals or entities with EINs that are no longer in use should follow the steps in Canceling an EIN-Closing Your Account.
