The Overlooked Tax Break For Retirement Savers That Many Couples Miss

If one spouse isn't working, many couples assume they can't contribute to an IRA for that person. That assumption is costing them real money.

In reality, the IRS allows something called a spousal IRA, which lets a working spouse fund a retirement account for a non-working or lower-earning spouse. It's one of the simplest ways for couples to boost retirement savings, yet it's widely underused. Here's how it works and why so many households miss out.

What a spousal IRA actually is

A spousal IRA is not a special type of account. It's a rule that allows a married couple to contribute to two separate IRAs, even if only one spouse has earned income. The official name is the Kay Bailey Hutchison Spousal IRA, but most people simply refer to it as a spousal IRA.

Normally, you need earned income to contribute to an IRA. With this rule, the working spouse's income can cover contributions for both partners. Each spouse still owns their own IRA. The accounts remain separate, with individual contribution limits, investment choices, and withdrawal rules.

How much couples can contribute

For the 2026 tax year, the contribution limit is $7,500 per person, or $8,600 for those age 50 or older. That means a qualifying couple could contribute up to $15,000 total, or as much as $17,200 if both spouses are 50 or older.

Even better, contributions can be made up until the tax filing deadline. For 2025 contributions, that means as late as April 15, 2026, and for couples trying to boost retirement savings later in life, this creates a valuable opportunity to catch up.

Why so many couples miss it

The biggest reason couples overlook the spousal IRA is simple confusion. Many assume that if one spouse is not earning a paycheck, that person cannot contribute to a retirement account. That is true for single filers, but not for married couples filing jointly.

Others assume they are already saving enough through a workplace retirement plan and do not revisit additional options. Data suggests this is a widespread issue. According to the Investment Company Institute, only about 37% of IRA-owning households were making contributions as of mid-2024.

Notably, that means the majority of households with IRAs are not actively adding to them, even when they may be eligible.

Traditional vs. Roth: choosing the right option

Couples using a spousal IRA can choose between a traditional IRA and a Roth IRA. A traditional IRA may offer an upfront tax deduction, depending on income levels and whether either spouse is covered by a workplace retirement plan. This can lower taxable income in the current year.

A Roth IRA does not provide a deduction upfront, but qualified withdrawals in retirement are tax-free. For many couples, the choice comes down to tax strategy.

Those who expect to be in a lower tax bracket in retirement may prefer the immediate deduction of a traditional IRA. Those who want tax-free income later or more flexibility in retirement may lean toward a Roth.

Using a mix of both can help create tax diversification, giving retirees more control over their income in the future.

The Saver's Credit

For some couples, the benefits of a spousal IRA do not stop with the contribution itself.

Lower- and moderate-income households may also qualify for the Saver's Credit, formally known as the Retirement Savings Contributions Credit. This credit can be worth up to $1,000 for single filers or $2,000 for married couples filing jointly, depending on income and contribution levels.

For example, a couple contributing $10,000 across two IRAs could potentially receive a tax credit in addition to any deduction or tax-free growth. That combination makes the spousal IRA one of the more powerful but overlooked tools available to retirement savers.

Who benefits the most

The spousal IRA can be especially valuable for couples in a few common situations.

It often applies to households where one spouse has stepped away from the workforce to raise children or care for family members. It can also apply to couples where one partner has already retired while the other is still working.

In both cases, the rule allows both spouses to continue building retirement savings, even if only one person is earning income.

It can also help address a common imbalance. Without a spousal IRA, one partner may accumulate significantly more retirement savings than the other, which can limit flexibility later.

Contributions as retirement approaches

As couples get closer to retirement, the ability to contribute meaningful amounts becomes more important. The years leading up to retirement are often the last opportunity to boost savings and reduce future tax exposure.

A couple in their 50s who contribute the full $17,200 annually for several years could significantly increase their retirement balance, especially when factoring in compound growth.

At the same time, contributions to a traditional IRA may reduce taxable income during peak earning years. That combination of immediate tax benefits and long-term growth makes the spousal IRA particularly valuable in the final stretch before retirement.

Bottom line

The spousal IRA is one of the most straightforward ways for couples to increase retirement savings, but many never take advantage of it. When combined with potential tax deductions, tax-free growth, and credits like the Saver's Credit, the impact can be significant.

For couples who have assumed they were limited by a single income, this is one tax break worth revisiting before the next filing deadline to help support a more stress-free retirement.
