What to know at First Interstate

First Interstate opens estate accounts under the Fiduciary Accounts clause of its deposit agreement, which lets executors and administrators under court orders open and maintain an account. Its online application excludes business, trust and other specialty accounts, which are opened at a branch, and does not say whether an estate account falls in that group.

First Interstate's published guidance does not state whether an estate account can be opened online. It states the account can be opened in a branch.

First Interstate asks for: Court order appointing the executor or administrator; Name, address, date of birth, and driver's license or other ID for the person opening the account.

First Interstate does not state the opening deposit, monthly fee, or fee-waiver balance for an estate account. The estate account carries the fees of whichever of First Interstate's 9 published accounts it is opened as.

An estate account is a bank account titled to the estate itself — not to the person who died and not to the executor personally. The court-appointed executor or administrator opens it to deposit money owed to the estate (final paychecks, refunds, proceeds from closed accounts), pay the estate's debts and expenses, and distribute what remains. Checks made out to "the Estate of" can only be deposited into an account titled this way.

The estate is its own taxpayer, separate from the person who died. Banks open estate accounts under the estate's Employer Identification Number (EIN) from the IRS, not the deceased's Social Security Number. The free EIN application prepares IRS Form SS-4 for the estate.
