What is a Spousal IRA?

Spousal IRA is an IRA that a non-working or lower-earning spouse can contribute to based on the couple’s combined earned income. It’s not a separate account type; it’s a regular Traditional or Roth IRA that uses an IRS rule allowing married couples filing jointly to fund both spouses’ retirement accounts even when one spouse doesn’t have a job.

Normally, you need earned income to contribute to an IRA. The spousal IRA exception changes that. As long as the working spouse earns enough to cover both contributions, the non-working spouse can max out their own IRA. For couples where one person stays home with kids, goes back to school, or takes a career break, this keeps retirement savings on track for both people rather than just the one with a paycheck.

Spousal IRA Rules

The IRS doesn’t actually use the term “spousal IRA.” The rule (IRC Section 219©) says that for married couples filing jointly, each spouse’s IRA contribution limit is based on the couple’s combined earned income rather than their individual income.

• You must file jointly. Married filing separately doesn’t qualify.
• The working spouse’s earned income must equal or exceed the total IRA contributions for both spouses combined.
• IRAs are always individually owned; there’s no such thing as a joint IRA. Each spouse opens and controls their own separate account.
• The same annual contribution limits, deadlines, and age rules apply to each spouse’s account independently.

The account belongs entirely to the spouse whose name is on it. The working spouse has no legal claim to or control over the other spouse’s IRA.

Spousal IRA Contribution Limits

Spousal IRA contributions follow the same annual limits as any other IRA. For 2026:

The combined maximum assumes both spouses max out. If the working spouse earns less than the combined limit, that earned income becomes the cap. A couple where the working spouse earns $10,000 can contribute up to $10,000 total across both accounts, split however they choose.

Contributions must be made by the tax filing deadline (typically April 15) for the tax year in question. You can contribute to one spouse’s IRA, the other’s, or both, as long as the total doesn’t exceed the working spouse’s earned income or the combined limit, whichever is lower.

Spousal Roth IRA vs. Traditional

A spousal IRA can be either Traditional or Roth, and the choice follows the same logic as any IRA decision.

Traditional spousal IRA: Contributions may be tax-deductible depending on income and whether either spouse is covered by an employer retirement plan. Withdrawals in retirement are taxed as ordinary income. The deduction rules for a non-working spouse are more generous than for someone covered by an employer plan, which makes the Traditional option attractive for many one-income households.

Spousal Roth IRA: Contributions are after-tax. Qualified withdrawals in retirement are completely tax-free, including all growth. Income limits apply; above a certain modified adjusted gross income (MAGI) threshold, direct Roth contributions aren’t allowed.

For many couples, the decision depends on whether you expect to be in a higher or lower tax bracket in retirement. If the non-working spouse plans to return to work and push the household into a higher bracket later, Roth contributions now can lock in today’s lower rate. If the household is in a high bracket now and expects lower income in retirement, the Traditional deduction has more value.

Spousal IRA Income Limits

Income limits depend on the account type and whether the working spouse has an employer retirement plan.

Roth spousal IRA (contribution limits)

Traditional spousal IRA (deduction limits)

An important detail: the working spouse’s own Traditional IRA deduction phases out at $129,000-$149,000 if they’re covered by an employer plan, while the non-working spouse’s deduction stays fully available up to $242,000 at the same income level. This asymmetry means it can make sense for the working spouse to contribute to a Roth while the non-working spouse takes the Traditional deduction.

Above the Roth income limits, you can still contribute to a Traditional IRA; it’s just non-deductible. That sets up the backdoor Roth strategy.

Spousal Backdoor Roth IRA

If your household income exceeds the Roth IRA limits, the backdoor Roth works the same way for a spousal IRA as for any other:

1. Contribute to a non-deductible Traditional IRA in the non-working spouse’s name
2. Convert the balance to a Roth IRA

The pro-rata rule applies to each spouse independently. If the non-working spouse has existing pre-tax Traditional IRA balances from a previous career, part of the conversion will be taxable. The cleanest path is to convert when the non-working spouse has no pre-tax IRA money to complicate the math.

This is one of the few strategies that lets high-income couples get Roth money into both spouses’ accounts regardless of income. For the full mechanics, see the backdoor Roth IRA guide.

Frequently Asked Questions

What is a spousal Roth IRA? A Roth IRA opened for a non-working or lower-earning spouse, funded based on the couple’s combined earned income. It follows all the same Roth IRA rules: contributions are after-tax, qualified withdrawals are tax-free, and income limits apply. The only difference from a regular Roth IRA is that the contribution is allowed without the account holder having their own earned income.

What are the spousal IRA contribution limits for 2026? The same as any IRA: $7,500 if you’re under 50 and $8,600 if you’re 50 or older. Each spouse has their own limit, so a couple can contribute up to $15,000-$17,200 combined depending on ages.

Can I contribute to a spousal IRA if my spouse works part-time? Yes. The spousal IRA rule applies whenever one spouse earns less than the contribution limit, not only when they earn zero. If your spouse earns $3,000 part-time, they can contribute up to their full individual limit as long as your combined earned income covers it.

What is a spousal inherited IRA? When your spouse dies and you inherit their IRA, you have options that non-spouse beneficiaries don’t. You can treat it as your own IRA (rolling it into your existing account or retitling it), which resets the required minimum distribution timeline based on your own age. This is generally the most flexible option for surviving spouses.
