Spousal IRA Contributions: The Underused Retirement Strategy for One-Income Households

Spousal IRA contributions are a provision under the Internal Revenue Code that lets a married couple contribute to two separate IRAs — even when only one spouse earns income. According to the IRS’s IRA contribution guidelines, the sole requirement is that the couple files a joint federal tax return and the contributing spouse has enough taxable compensation to cover both contributions. For 2025, that means a working spouse can fund up to $14,000 total across both accounts, or $16,000 if both partners are 50 or older.

Despite its power, this strategy is dramatically underused. One-income households — including families where one partner stays home to raise children, care for an aging parent, or manages a household — often leave this tax-advantaged space completely empty, creating a retirement savings gap that compounds over decades.

What Exactly Is a Spousal IRA and How Does It Work?

A spousal IRA is not a special account type — it is a standard Traditional IRA or Roth IRA opened in the non-working spouse’s name and funded using the working spouse’s earned income. The account belongs entirely to the non-working spouse, who controls investment decisions and beneficiary designations independently.

The mechanics are straightforward. The couple must file as Married Filing Jointly. The working spouse’s earned income must equal or exceed the combined contributions to both IRAs. If the working spouse earns $20,000, they can contribute $7,000 to their own IRA and $7,000 to their spouse’s IRA — for a total of $14,000 — since $20,000 exceeds that combined amount.

Traditional vs. Roth: Which Account Type to Choose?

The choice between a Traditional and Roth spousal IRA follows the same logic as any IRA decision. A Traditional spousal IRA may provide a tax deduction now, subject to income limits if the working spouse has a workplace retirement plan. A Roth spousal IRA offers tax-free growth and withdrawals in retirement, with eligibility phasing out for joint filers with a modified adjusted gross income (MAGI) above $236,000 in 2025 per IRS limits.

What Are the 2025 Contribution Limits and Eligibility Rules?

For 2025, the standard IRA contribution limit is $7,000 per person, with a $1,000 catch-up contribution allowed for those age 50 and over, bringing the individual limit to $8,000. A couple where both spouses are 50 or older can collectively shelter $16,000 per year using this strategy.

Eligibility for spousal IRA contributions hinges on three rules. First, the couple must file a joint return. Second, the contributing spouse must have taxable compensation — wages, salaries, self-employment income, or alimony received under pre-2019 agreements qualify; investment income and Social Security do not. Third, the couple’s combined contribution cannot exceed the working spouse’s total earned income for the year.

Income Limits for Roth Spousal IRAs

Roth spousal IRA contributions phase out between a MAGI of $236,000 and $246,000 for joint filers in 2025. Above $246,000, direct Roth contributions are not permitted — though the backdoor Roth IRA strategy remains an option for higher earners. For Traditional spousal IRA deductibility, limits depend on whether the working spouse participates in an employer plan, with the deduction phasing out between $126,000 and $146,000 of MAGI in 2025.

How Much Does a Spousal IRA Actually Grow Over Time?

The compounding impact of spousal IRA contributions is substantial and often underestimated. A non-working spouse who begins receiving spousal IRA contributions at age 35, with $7,000 annually, accumulates roughly $735,000 by age 65 assuming a 7% average annual return — the commonly cited long-term equity market estimate.

Without a spousal IRA, that same non-working spouse enters retirement with zero personal retirement savings, creating a dangerous dependency on a single account and Social Security income. This gap is especially risky in divorce, disability, or the early death of the working spouse — scenarios where a separate, individually owned account provides critical financial protection. If managing finances as a one-income household feels complex, reviewing strategies for structuring joint versus separate finances after marriage can help clarify where retirement savings fit within your broader plan.

The Compounding Cost of Delay

Waiting just five years — starting contributions at 40 instead of 35 — reduces that projected balance to approximately $510,000 under the same assumptions. That $225,000 difference illustrates why financial planners consistently stress that time in the market is the most powerful variable available to younger households.

What Are the Tax Benefits of Spousal IRA Contributions?

Spousal IRA contributions generate the same tax advantages as any IRA — and for one-income households, those benefits can be especially concentrated. A Traditional spousal IRA contribution is potentially fully deductible if the working spouse does not participate in a workplace retirement plan such as a 401(k) or 403(b), regardless of income level.

For households where the working spouse does have a workplace plan, the deductibility of a Traditional spousal IRA for the non-working spouse follows a separate, more generous phase-out range. The non-working spouse’s deduction phases out between a MAGI of $236,000 and $246,000 in 2025 — meaning many middle-income families can still deduct the full spousal IRA contribution even when the working spouse’s Traditional IRA deduction is limited.

For households focused on long-term tax efficiency, a Roth spousal IRA is often the stronger choice. Contributions grow tax-free, qualified withdrawals are tax-free, and Roth IRAs are not subject to Required Minimum Distributions (RMDs) during the owner’s lifetime under current law. To understand how RMD rules have evolved, see our breakdown of what changed in Required Minimum Distributions in 2026. For households also using Health Savings Accounts, pairing an HSA with a spousal IRA can create a powerful dual tax shelter — a strategy covered in detail in our guide to HSAs as a retirement tool.

What Mistakes Do Couples Make With Spousal IRA Contributions?

The most common mistake is simply not making the contribution at all. According to data from the Employee Benefit Research Institute (EBRI), a significant share of IRA-eligible households contribute nothing in a given year, with non-working spouses especially likely to have zero retirement savings in their own name.

A second frequent error is contributing more than the working spouse’s earned income. If the working spouse earns only $8,000 in a tax year — from part-time work or self-employment — total spousal IRA contributions cannot exceed $8,000 across both accounts. Excess contributions are subject to a 6% excise tax per year until corrected, per IRS rules.

Couples also commonly overlook the contribution deadline. Spousal IRA contributions for a given tax year can be made up to the federal tax filing deadline — typically April 15 of the following year — giving households additional time to fund accounts even after the calendar year ends. If you are also working to eliminate debt before ramping up retirement contributions, our article on budgeting mistakes that keep people broke even on a good salary covers how to prioritize competing financial goals. Additionally, if the working spouse has an old 401(k), understanding common 401(k) rollover mistakes can prevent costly errors when consolidating retirement assets.

Frequently Asked Questions

Can I contribute to a spousal IRA if my spouse had no income at all this year?

Yes. A non-working spouse with zero earned income qualifies for spousal IRA contributions as long as the working spouse has sufficient taxable compensation and the couple files a joint return. The contribution is made to an account in the non-working spouse’s name.

Does a spousal IRA count toward the working spouse’s contribution limit?

No. A spousal IRA contribution counts against the non-working spouse’s individual annual limit, not the working spouse’s. Each spouse has a separate $7,000 limit ($8,000 if 50+), allowing a combined $14,000 contribution from one income source.

What happens to a spousal IRA in a divorce?

Because the spousal IRA is legally owned by the non-working spouse, the account belongs to them outright — not to the working spouse who funded it. In a divorce, the account is treated as the non-working spouse’s separate retirement asset, subject to any applicable state law or divorce decree provisions.

Can we do both a spousal IRA and a 401(k) in the same year?

Yes. IRA contributions and 401(k) contributions are governed by separate limits and can be made simultaneously. The working spouse can maximize their 401(k) — up to $23,500 in 2025 — and both spouses can still contribute to their respective IRAs, subject to income limits for deductibility.

Is there an age limit for spousal IRA contributions?

No age limit applies to Traditional or Roth IRA contributions under current law. The SECURE 2.0 Act eliminated the prior age cap of 70.5 for Traditional IRA contributions. As long as the working spouse has earned income and the couple files jointly, spousal contributions are permitted at any age.

Can a self-employed spouse fund a spousal IRA?

Yes. Self-employment income, including income from freelance work, sole proprietorships, or partnerships, qualifies as earned income for IRA contribution purposes. A self-employed working spouse can fund both their own IRA and a spousal IRA, and may also contribute to a Solo 401(k) in the same tax year for additional retirement savings capacity.
