According to the IRS, an entity that is not a bank (or an insurance company in the case of Archer Medical Savings Accounts and health savings accounts) can request to be a nonbank trustee/custodian by applying in writing and demonstrating that certain requirements will be met.
The IRS says that it will post periodic updates to the list on its web site, and that it will “frequently update this list” as other nonbank trustees or custodians are added or removed. Entities will be removed from the list after their withdrawal or revocation has become final.
The IRS notes that an approved nonbank trustee or custodian is required to notify the IRS of any change in entity name, address or any other change that may affect the entity’s status as an approved nonbank trustee or custodian.
The list, as of September 1, 2011, is at http://www.irs.gov/pub/irs-tege/nonbank_trustee_list.pdf.
