What Is an IRA Share Account and How Does It Work?

An IRA share account is a retirement account at a credit union where your money sits as an insured deposit earning a fixed dividend rate, rather than being invested in stocks or bonds. It’s a savings account wearing the tax rules of an Individual Retirement Arrangement. For 2026, you can put in up to $7,500 ($8,600 if you’re 50 or older), and the balance is federally insured up to $250,000 by the National Credit Union Share Insurance Fund.¹

How It Differs From a Brokerage IRA

At a brokerage firm, an IRA holds investments — mutual funds, ETFs, individual stocks — and the value rises and falls with the market. An IRA share account holds cash or cash equivalents and pays a dividend rate set by the credit union. Your principal doesn’t fluctuate.

The word “share” is credit union terminology. When you deposit money at a credit union, you’re technically buying ownership shares in a cooperative rather than making a deposit at a for-profit bank. Your retirement funds represent shares in the institution, and the credit union pays dividends on those shares instead of interest.

The trade-off is predictability in exchange for lower long-term returns. Historically, diversified stock portfolios have outpaced savings-style returns over long periods, and the gap compounds meaningfully over decades. For someone five years from retirement who can’t stomach a downturn, that trade often makes sense. For a 30-year-old, using a share account as the only retirement vehicle is a harder case.

Share Account vs. Share Certificate

Credit unions usually offer two deposit-based IRA products, and they’re not the same thing.

An IRA share account works like a regular savings account. You can add money whenever you want within IRS limits, and the dividend rate may adjust over time.

An IRA share certificate is the credit union version of a bank CD. You lock the money in for a set term, commonly 30 days to 60 months, and in exchange you typically earn a higher fixed rate. Withdraw before the term ends and you’ll owe an early withdrawal penalty to the credit union, which is separate from any IRS penalty for taking retirement money out early.

Both types carry the same federal insurance. NCUSIF coverage on IRA and Keogh retirement accounts is up to $250,000 per member, separate from the coverage on your regular checking or savings at the same credit union.¹

The Tax Wrapper You Choose

The share account is just the container. How the money is taxed depends on which type of IRA you open on top of it. Credit unions commonly offer three.

Traditional IRA

Contributions may be tax-deductible, which lowers your taxable income for the year you contribute. Whether you get the full deduction, a partial one, or none depends on your income and whether you or your spouse have access to a workplace retirement plan.² The money grows tax-deferred. You pay ordinary income tax on withdrawals in retirement.

Roth IRA

Roth contributions are made with money you’ve already paid taxes on, so there’s no upfront deduction. Qualified withdrawals in retirement come out completely tax-free, growth included. Roth IRAs also have income eligibility limits: for 2026, contributions phase out between $153,000 and $168,000 in modified adjusted gross income for single filers, and between $242,000 and $252,000 for married couples filing jointly.³ Above the top of the range, you can’t contribute directly to a Roth at all.

SEP IRA

The Simplified Employee Pension IRA is for self-employed individuals and small business owners. Only the employer contributes; employees don’t contribute separately, and contributions are tax-deductible to the business.⁴ The contribution ceiling is far higher than the Traditional or Roth limit, which is why high-earning self-employed people gravitate toward it.

Contribution Limits and Who Can Contribute

For the 2026 tax year, the combined limit across all your Traditional and Roth IRAs is $7,500, or $8,600 if you’re 50 or older (the extra $1,100 is the catch-up contribution).⁵ If you have both types, the total going into both accounts can’t exceed that figure.⁶

You can only contribute up to the amount of your earned income for the year. Wages, salaries, commissions, and net self-employment earnings count; passive income like dividends, rental income, and pension payments doesn’t.⁷ One exception matters for couples: if you file jointly, a non-working spouse can contribute to their own IRA based on the working spouse’s income, and each spouse can contribute up to the full limit as long as combined earned income covers both.⁶

SEP IRA limits work differently. For 2026, an employer can contribute the lesser of 25% of an employee’s compensation or $72,000.⁸

You have until the federal tax filing deadline to make contributions for a given tax year, so contributions for the 2025 tax year are due by April 15, 2026.⁹

Being able to contribute is not the same as being able to deduct. Anyone with earned income can contribute to a Traditional IRA, but the deduction phases out at certain income levels if you or your spouse are covered by a workplace retirement plan. For 2026, the phase-out ranges are $81,000 to $91,000 for a single filer covered at work, $129,000 to $149,000 for married filing jointly when the contributor is covered, and $242,000 to $252,000 when the contributor isn’t covered but the spouse is. If neither spouse is covered by a workplace plan, the deduction applies in full at any income level.³

Getting Money Out

The number that governs IRA withdrawals is 59½. Take money out before that age and you’ll generally owe income tax on the taxable portion plus a 10% early withdrawal penalty from the IRS.¹⁰ That 10% is on top of regular income tax.

The IRS waives the 10% penalty in specific situations, including:

First-time home purchase, up to $10,000 over your lifetime.
Higher education expenses for you, your spouse, or dependents.
Unreimbursed medical expenses that exceed 7.5% of adjusted gross income.
Amounts seized from your plan by an IRS levy.
Total and permanent disability.

These exceptions waive the penalty, not the income tax. A Traditional IRA distribution still gets taxed as ordinary income even when a penalty exception applies.¹⁰

Traditional and SEP IRAs require you to start taking withdrawals at age 73.¹¹ The required minimum distribution each year is based on your prior year-end balance and a life expectancy factor from IRS tables. Skip or shortchange your RMD and you face a 25% excise tax on the shortfall, which drops to 10% if you correct it within two years.¹²

Roth IRAs have no RMD requirement during the original owner’s lifetime.¹²

Who It’s a Good Fit For

An IRA share account works best when preserving what you have matters more than growing it fast. If you’re within a few years of retirement and can’t afford to ride out a market crash, an insured share account or share certificate eliminates that risk. The same logic applies to retirees already drawing income who want a portion of the portfolio completely stable.

Younger savers can still use one — just not as the whole plan. Nothing stops you from holding an IRA share account alongside a brokerage IRA and treating the share account as the low-risk slice of a broader strategy. Credit unions sometimes pay slightly higher dividend rates than banks offer on comparable savings products, and the $250,000 per-member NCUA insurance on IRA accounts provides the same protection as FDIC coverage at a bank.¹³ If capital preservation and simplicity are the goal, an IRA share account delivers both.
