A fixed term IRA is an ordinary Individual Retirement Account that holds a certificate of deposit instead of stocks or mutual funds. The money earns a guaranteed interest rate for a term you pick at the outset, commonly six months to five years, and your ending balance is calculable to the penny the day you open it. The account is not a separate category under federal tax law. It is a Traditional or Roth IRA whose underlying investment happens to be a CD.
How a Fixed Term IRA Works
When you open one at a bank or credit union, you are doing two things at once: setting up a tax-advantaged retirement account and purchasing a CD inside it. The bank locks in an interest rate for the chosen term, and that rate stays the same regardless of what broader interest rates do while your money is tied up.
The predictability is the entire point. An IRA invested in an S&P 500 index fund could swing 20% in either direction over a year. A fixed term IRA trades that upside for certainty: the principal does not drop in value, and interest accrues on a set schedule. For someone within a few years of retirement who cannot afford a market downturn, that tradeoff often makes sense.
One distinction worth knowing: CDs held in IRAs come in two varieties. A bank CD is purchased directly from the issuing institution, earns interest from the deposit date, and carries an early withdrawal penalty if you cash out before maturity. A brokered CD is purchased through a brokerage account and may be sold on a secondary market before maturity instead of redeemed early, but the sale price fluctuates with interest rates and there is no guarantee of finding a buyer. Most fixed term IRAs at banks and credit unions use bank CDs. If you are working through a brokerage, ask which type you are getting, because the liquidity rules differ significantly.
Contribution rules are the same as for any other IRA. For 2026 the annual cap is $7,500, or $8,600 if you are 50 or older, and you need earned income to contribute at all.1Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,5002Office of the Law Revision Counsel. 26 U.S. Code 219 – Retirement Savings
Traditional or Roth: Which Tax Wrapper
“Fixed term IRA” describes what is inside the account. The tax rules depend on whether you opened a Traditional IRA or a Roth IRA to hold the CD.
With a Traditional IRA, your contribution may be tax-deductible in the year you make it, and the CD’s interest grows tax-deferred. You pay income tax only when you withdraw the money in retirement. Whether the deduction is available depends on your income and whether you or your spouse are covered by a workplace retirement plan.3Internal Revenue Service. IRA Deduction Limits Even if your income is too high to deduct, you can still make a nondeductible Traditional contribution, and the interest still grows tax-deferred.
A Roth IRA flips the timing. You contribute money you have already paid tax on, and in exchange, the interest the CD earns and your eventual withdrawals come out tax-free, provided you follow the qualification rules.4Office of the Law Revision Counsel. 26 USC 408A – Roth IRAs For the withdrawal to be fully tax-free, it must be a “qualified distribution,” which requires two conditions: you must be at least 59½, and at least five tax years must have passed since your first Roth IRA contribution of any kind. The five-year clock starts on January 1 of the tax year of that first contribution. Pull earnings out before meeting both tests and you will owe income tax on the earnings portion and potentially the 10% early withdrawal penalty too.
What Happens When the CD Matures
This is where people get tripped up. A fixed term IRA has an internal timeline, the CD’s maturity date, that runs independently of the broader IRA rules. When your CD reaches the end of its term, the bank gives you a grace period to decide what to do. Federal regulations require at least five calendar days when the bank uses an alternative disclosure method, and most banks offer seven to ten days in practice.5eCFR. 12 CFR Part 1030 – Truth in Savings (Regulation DD)
During the grace period, you have three choices: roll the money into a new CD at the current rate, move it into a different investment within the same IRA, or transfer it to an IRA at another institution. Do nothing and the bank will almost certainly auto-renew the CD into a new term at whatever rate it is currently offering, which may be meaningfully higher or lower than your old one. Once auto-renewal kicks in you are locked up again and would face an early withdrawal penalty to get out.
None of these moves is a taxable event as long as the money stays inside an IRA. Shifting a matured CD into a money market fund at the same custodian, or sending it to another bank’s IRA, is not a distribution. You are rearranging what sits inside the tax-advantaged wrapper.
Early Withdrawal Hits You Twice
Pulling money from a fixed term IRA before you are supposed to can cost you twice, because two independent penalty systems apply at the same time.
The Bank’s CD Penalty
Cash out a CD before its maturity date and the issuing bank will charge an early withdrawal penalty. Federal law sets a floor of seven days’ simple interest for withdrawals within the first six days after deposit, but no federal cap on the penalty applies after that.6HelpWithMyBank.gov. What Are the Penalties for Withdrawing Money Early From a CD? Banks commonly charge anywhere from three to twelve months of interest depending on the term. A five-year CD will carry a steeper penalty than a one-year CD. Read the account agreement before you buy; these terms vary widely.
The IRS’s 10% Penalty
Separately, if you take a distribution from any IRA before age 59½, the IRS adds a 10% tax on the taxable portion of the withdrawal.7Office of the Law Revision Counsel. 26 U.S. Code 72 – Annuities; Certain Proceeds of Endowment and Life Insurance Contracts For a Traditional IRA, you will also owe regular income tax on the full amount withdrawn. These federal consequences apply regardless of whether the CD has matured. You could wait until the CD’s term ends, dodge the bank penalty entirely, and still get hit with the IRS penalty if you are under 59½.
The IRS does carve out exceptions to the 10% penalty, including a first home purchase (up to $10,000 lifetime), qualified higher education expenses, unreimbursed medical expenses above 7.5% of adjusted gross income, health insurance premiums while unemployed, total and permanent disability, up to $5,000 per child for a birth or adoption, up to $1,000 once per calendar year for emergency personal expenses, and up to $22,000 for federally declared disaster losses. The full list is longer.8Internal Revenue Service. Retirement Topics – Exceptions to Tax on Early Distributions Even when an exception applies, you still owe regular income tax on Traditional IRA withdrawals. The exception only waives the extra 10%.
Required Minimum Distributions and CD Terms
If your fixed term IRA is a Traditional IRA, the IRS will eventually force you to start withdrawing money. Under current law, required minimum distributions begin the year you turn 73, with the first RMD due by April 1 of the following year and subsequent RMDs due by December 31 each year.9Internal Revenue Service. Retirement Plan and IRA Required Minimum Distributions FAQs The RMD age is scheduled to rise to 75 in 2033.
This matters more for fixed term IRAs than for other kinds, because your CD may not mature when you need to take a distribution. If an RMD comes due and your money is locked in a three-year CD with two years remaining, you will either break the CD early and eat the bank’s penalty or need other IRA funds available to satisfy the requirement. Planning your CD terms around your RMD schedule becomes essential once you approach 73. Missing an RMD triggers a 25% excise tax on the shortfall, dropping to 10% if you correct it within two years.10Internal Revenue Service. Retirement Topics – Required Minimum Distributions (RMDs)
Roth IRAs have no RMDs during the original owner’s lifetime, which is one practical reason to use a Roth as the wrapper for a long-term CD.
FDIC and NCUA Insurance
Because a fixed term IRA holds a deposit product rather than securities, it qualifies for federal deposit insurance. At a bank, the FDIC covers IRA deposits up to $250,000 per depositor, per institution.11FDIC.gov. Financial Institution Employee’s Guide to Deposit Insurance – Certain Retirement Accounts At a credit union, the NCUA provides the same $250,000 limit.12National Credit Union Administration. How Your Accounts Are Federally Insured
IRA deposit insurance is separate from coverage on your regular checking or savings accounts at the same institution. You could hold $250,000 in a personal savings account and another $250,000 in an IRA CD at the same bank and have both fully insured. If you hold multiple IRAs at the same bank, though, those balances are combined for insurance purposes, and naming beneficiaries does not raise the ceiling. When your IRA balances at one institution approach $250,000, spread new deposits across other banks or credit unions.
