A custodial fee is simply a flat fee charged by a bank or brokerage for administering or managing an IRA. Virtually every type of IRA is associated with some type of custodial fee, regardless of whether you choose a certificate of deposit, a mutual fund or some other type of IRA.
Unfortunately, the Roth IRA maintenance fee is not the only typical charge levied on accounts. One common IRA fee is an account closing fee. Customers are charged this fee if they close their IRA account or transfer it to another firm.hat means that annual maintenance fees on Roth IRAs can add up to big money. Someone who starts an IRA at age 20 and pays a $30 annual maintenance fee will have paid almost $1,200 in fees by the time they can withdraw the money without penalty at age 59 1/2.
