For faster processing, fax your information to the fax number in the letter using either a fax machine or an online fax service. Protect yourself when sending digital data by understanding the fax service’s privacy and security policies. Do not mail us your response if you have faxed it.

- It’s critical the IRS has accurate information in cases of identity theft or other fraud issues related to EINs or business accounts.
- Data around the "responsible parties" for business-type entities is often outdated or incorrect, meaning the IRS doesn’t have accurate records of who to contact. All EIN applications (mail, fax, electronic) must disclose the: Name and taxpayer identification number (Social Security number, individual taxpayer identification number or EIN) of the true principal officer, general partner, grantor, owner or trustor
- The IRS defines the responsible party as the individual or entity who "controls, manages, or directs the applicant entity and the disposition of its funds and assets." Unless the applicant is a government entity, the responsible party must be an individual, not an entity.
- If there is more than one responsible party, the entity may list whichever party the entity wants the IRS to recognize as the responsible party.
- Entities with EINs that are no longer in use should close their IRS tax accounts and follow steps outlined at Canceling an EIN - Closing your account
