An account holder should enter into an IRA adoption agreement for traditional and Roth IRAs, as well as for education and savings accounts and health savings accounts (HSAs). Such an agreement is also concluded for qualified plans, simple IRAs, IRAs sep and a large number of employer-funded pension plans. The Internal Revenue Service (IRS) provides information guides and forms for introducing ERI and planned documentation in the form of the 5305 series. An ERI adoption agreement must be accompanied by a basic planning document explaining how a plan works. An IRA adoption agreement and a plan document are a contract between the owner of an IRA and the financial institution with which the account is kept. The IRA adoption agreement and plan document must be signed by the account holder before the individual pension account (IRA) can be valid.
