IRAs at a bank

An Individual Retirement Account is a tax-advantaged account established under §408 (and related sections) of the Internal Revenue Code. The IRA is a legal structure, not a product type. Inside the IRA, the assets can be a bank deposit, a brokerage portfolio of securities, a mutual fund holding, or in narrow cases other types of investment. A "bank IRA" is an IRA whose underlying assets are deposit products at an FDIC-insured bank — typically a savings account, a money market deposit account, or a certificate of deposit. The bank serves as the IRA custodian, the deposit is the underlying asset, and the tax treatment is determined by the IRA's status under the Code.

This article describes what a bank IRA actually is, how its parts fit together, how FDIC insurance treats it, and how it differs from a brokerage IRA. It does not give tax advice on contribution limits, conversion strategies, required minimum distributions, early-withdrawal penalties, or estate-planning considerations; those are matters for the IRS publications and for a qualified tax professional.

The two layers

A bank IRA has two distinct layers that the depositor should keep separate in their thinking.

The tax wrapper is the IRA itself: a legal arrangement governed by the IRC under which contributions, growth, and distributions are subject to defined tax treatment. The principal IRA types are the Traditional IRA (contributions may be tax-deductible, growth is tax-deferred, distributions are taxed as ordinary income in retirement), the Roth IRA (contributions are not deductible, growth is tax-free, qualified distributions in retirement are tax-free), the SEP-IRA (a simplified employer-sponsored version for self-employed people and small businesses), and the SIMPLE IRA (another employer-sponsored variant). Each has contribution limits, eligibility rules, and distribution requirements that the IRS publishes and updates annually.

The underlying asset is whatever the IRA actually holds. At a bank, this is typically a savings account, an MMDA, or a CD; the IRA custodian (the bank) reports the assets to the IRS on the appropriate forms. The same IRA could, at a brokerage, hold securities; at a mutual fund company, hold fund shares. The choice of underlying asset is operationally important — it determines the yield, the liquidity, and the risk characteristics — but does not change the tax treatment, which is determined by the wrapper.

This separation is what allows a depositor to move an IRA among institutions through a trustee-to-trustee transfer (a direct transfer between custodians that does not trigger taxable distribution) or an indirect rollover (a distribution to the depositor followed by a redeposit within 60 days). The wrapper persists; the underlying asset changes.

What a bank IRA holds, in practice

The typical bank IRA holds one or more of:

• A savings or money market deposit account, paying interest at the bank's posted rate. Suitable for IRA holders who want full liquidity and federal insurance on the entire balance.
• One or more CDs ("IRA CDs"), which operate identically to non-IRA CDs but live inside the tax wrapper. Suitable for IRA holders who want a higher fixed rate and accept the early-withdrawal penalty in exchange.
• A combination: a CD ladder inside the IRA, or a CD alongside a savings account that receives rollovers or contributions.

What a bank IRA does not typically hold is securities: stocks, bonds, mutual funds, ETFs. To hold those inside an IRA, the depositor needs a brokerage IRA (sometimes called a self-directed IRA, although that term has additional technical meanings). The bank IRA is therefore appropriate for the deposit-and-CD portion of a retirement portfolio; for asset classes outside deposits, a brokerage IRA is the right vehicle.

FDIC insurance on a bank IRA

Deposits held inside an IRA at an FDIC-insured bank are insured under the "certain retirement accounts" ownership category of FDIC coverage. The coverage limit is the standard $250,000 per IRA owner per insured bank, aggregating all IRA-type accounts (Traditional, Roth, SEP, SIMPLE, self-directed Keogh) the same owner holds at the same bank. The IRA owner's IRA deposits are insured separately from the same owner's non-IRA deposits at the same bank (a single-ownership savings account, for example) because the IRA is in a different ownership category.

Two practical implications. First, a single depositor can have $250,000 of insured non-IRA deposits and $250,000 of insured IRA deposits at the same bank, with full coverage on both. Second, IRA deposits at multiple banks are independently insured up to $250,000 each; spreading a large IRA across multiple bank CD issuers extends coverage beyond the single-bank limit. The brokered-CD market makes this operationally simple inside a brokerage IRA, but bank-direct IRAs at multiple institutions achieve the same effect.

The tax wrapper does not change the insurance status. An IRA holding a deposit is insured as a deposit; an IRA holding a money market mutual fund (in a brokerage IRA) is not, because the underlying asset is a mutual fund rather than a deposit. The IRA wrapper governs taxation; the underlying asset governs insurance.

Bank IRA versus brokerage IRA

The trade-offs between holding an IRA at a bank and at a brokerage are direct:

• Asset universe. Bank IRA: deposits and CDs. Brokerage IRA: deposits (in a cash sweep), CDs (brokered), mutual funds, ETFs, individual securities, sometimes options.
• Insurance. Bank IRA: FDIC insurance on the underlying deposit. Brokerage IRA: SIPC coverage on the brokerage account (with limits and a different structure); no FDIC insurance on securities, FDIC pass-through coverage on bank-deposit sweep features.
• Yield. Bank IRA: whatever the bank pays on its deposits, varying widely (often higher at online-first or credit-union institutions). Brokerage IRA: depends on the investments held; a Treasury-bill ladder inside a brokerage IRA can outperform many bank IRAs in periods of elevated short-term rates.
• Fees. Bank IRA: typically a small annual custodial fee, sometimes waived. Brokerage IRA: depends on the brokerage's fee schedule and on the funds and trading activity inside.
• Operational simplicity. Bank IRA: simple; little active management required. Brokerage IRA: more flexible but requires investment decisions.

The two are not mutually exclusive. A depositor may maintain a bank IRA for a CD component of their retirement allocation and a brokerage IRA for an equity component; trustee-to-trustee transfers allow movement between them.

Contribution, distribution, and rollover mechanics

Contributions to an IRA are made up to annual limits set by the IRS, with separate limits for traditional, Roth, and catch-up contributions for IRA holders aged 50 or over. The contribution-limit figures are adjusted for inflation; for 2025, the regular contribution limit is $7,000 with a $1,000 catch-up contribution for those 50 or older — verify against the IRS's most recent guidance before relying on a specific figure. Eligibility for tax-deductible Traditional IRA contributions and for Roth IRA contributions is phased out at higher income levels under rules specified in the Internal Revenue Code.

Distributions from a Traditional IRA before age 59½ are typically subject to a 10% additional tax on top of ordinary income tax, with exceptions for specific qualifying purposes (first-time home purchase up to a defined limit, certain education expenses, etc.). Roth IRA distributions of contributions can be taken without tax or penalty at any time; distributions of earnings before age 59½ or before the five-year rule is satisfied may be subject to tax and penalty. Required Minimum Distributions begin at the IRS-specified age (currently 73 under SECURE Act 2.0, scheduled to rise) for Traditional IRAs; Roth IRAs do not have RMDs during the original owner's lifetime.

The mechanics of contribution and distribution at a bank IRA are typically handled by the bank's IRA-specialist staff. Trustee-to-trustee transfers and 60-day rollovers are processed through standardized forms. The tax-reporting forms (5498 for contributions, 1099-R for distributions) are issued by the IRA custodian — at a bank IRA, by the bank.

Limits and uncertainty

The IRA framework is set by the Internal Revenue Code and amended periodically by Congress; SECURE Act (2019) and SECURE Act 2.0 (2022) substantially revised the rules around required minimum distributions, inherited IRAs, and catch-up contributions. The specific contribution limits, RMD ages, and phase-out thresholds are adjusted annually by the IRS and should be checked against current guidance before relying on a specific figure. The FDIC insurance treatment of bank IRAs is set by 12 CFR Part 330 and is durable. The choice between a bank IRA and a brokerage IRA is a question of asset allocation and personal preference, on which this article does not give advice.
