The spousal IRA: retirement savings for a non-earning spouse

Normally, you need earned income to contribute to an IRA — no paycheck, no contribution. The spousal IRA is the exception, and it exists precisely because raising kids or managing a household is work that doesn't come with a W-2. If you're married filing jointly and one spouse earns enough to cover it, the non-earning (or low-earning) spouse can fund a full IRA of their own every year. It's not a special account — it's a regular IRA using the household's income to qualify.

How the rule works

• You must be married and file taxes jointly.
• The working spouse's earned income must cover both spouses' total contributions.
• Each spouse can contribute up to the normal limit — $7,000 in 2025, or $8,000 if 50 or older. A couple can shelter up to $14,000–$16,000 a year this way.
• The account belongs entirely to the spouse whose name is on it — it is their asset, not a joint one, regardless of whose paycheck funded it.
• It can be a Roth IRA (subject to the household's joint income limits) or a traditional IRA (deductibility depends on income and workplace-plan coverage).

Why this matters more than it looks

Career breaks are the biggest silent driver of retirement gaps, especially for women, who take most caregiving years and then live longer on smaller balances. A parent who steps out of the workforce from 30 to 40 doesn't just lose ten years of salary — they lose ten years of 401(k) matches and compounding at the front of the curve, where compounding matters most. The spousal IRA is the tool that keeps the flywheel spinning through those years.

Roth vs. traditional for the spousal IRA

For most single-income households, Roth wins. The household is often in a lower bracket during one-income years than it will be later with two incomes — pay today's lower rate and never pay tax on the growth. A traditional spousal IRA makes sense mainly when household income is high and the deduction is both available and valuable. When in doubt, Roth is the forgiving default: contributions can be withdrawn anytime, and there are no required distributions later.

Setting it up takes fifteen minutes

1. Open an IRA in the non-earning spouse's name at any major brokerage — there is no product called a 'spousal IRA'; it's just an IRA.
2. Link the household checking account and set an automatic monthly transfer ($583/month maxes the 2025 limit).
3. Invest the contributions — a target-date fund or three-fund portfolio is plenty. Cash sitting uninvested is the most common IRA mistake.
4. Confirm at tax time that the working spouse's earned income covers both spouses' contributions and that you're filing jointly.
5. Revisit the Roth income limits each year if household income is climbing; the backdoor Roth works for spousal contributions too.

What the gap years cost without it

The chart shows two things at once. First, the obvious one: funding versus not funding the at-home years is a six-figure difference at retirement. Second, the subtler one: the same ten years of contributions are worth more than twice as much when the break happens young, because every dollar gets an extra decade of compounding. Households often deprioritize retirement saving precisely when a parent leaves work in their early 30s — which is exactly when each skipped contribution is most expensive.

Common spousal IRA mistakes

• Assuming ineligibility. The number-one issue is simply not knowing the rule exists — surveys of one-income couples consistently show most have never funded an IRA for the at-home spouse.
• Filing separately. Married-filing-separately kills the spousal IRA (and nearly all Roth eligibility). The rule requires a joint return.
• Stopping contributions during part-time years. If the at-home spouse earns some income, they can contribute based on their own earnings AND still top up under the spousal rule as long as combined contributions don't exceed the working spouse's income plus their own.
• Leaving the money in cash. The contribution is step one; unbought index funds don't compound. Check the account once a year.
• Forgetting the catch-up: from age 50 the at-home spouse's limit rises to $8,000 too — the catch-up isn't reserved for workers.
• Missing the deadline flexibility: contributions for a given tax year can be made until the April filing deadline, so a bonus in February can still fund last year's IRA.

Where it fits in the household plan

Order matters when dollars are limited. Capture the working spouse's full 401(k) match first — that's an instant 50-100% return. Then fund both IRAs, the spousal one included, before maxing the rest of the 401(k), because IRAs typically offer cheaper funds and the Roth version adds tax diversification the household otherwise lacks. A one-income couple following just those two steps — match plus two IRAs — is saving roughly $18,000-$21,000 a year in tax-advantaged accounts, which at typical returns builds a seven-figure joint retirement over a career even if they never do anything fancier.

The bottom line

One income doesn't have to mean one retirement account. If your household includes a spouse out of the workforce — for kids, caregiving, school, or anything else — the spousal IRA keeps their retirement compounding and puts assets in their name. It's fifteen minutes of setup, up to $16,000 a year of shelter, and one of the most underused rules in the entire tax code.
