If one spouse is working and the other is not, retirement saving can feel lopsided fast. One 401(k) balance grows while the other person has a blank space and that blank space can create real anxiety, especially for stay-at-home parents who are doing a ton of unpaid labor.
The good news: the IRS has a clean workaround called a spousal IRA. It is not a special account type. It is a rule that allows a working spouse’s earned income to support IRA contributions for a spouse with little or no earned income, as long as you file the right way.
Below I will walk you through eligibility, contribution limits, stay-at-home versus low-income situations, Roth versus traditional decisions specifically for spousal rules, and how to coordinate everything when one or both spouses also have a workplace plan.
What a spousal IRA is
A spousal IRA is simply an IRA in the non-working or lower-income spouse’s name that is funded using the couple’s combined financial picture.
- Ownership matters: The IRA belongs to the spouse whose name is on the account, even if the other spouse earned the income or transferred the dollars.
- Two accounts, two limits: A spousal IRA does not “share” an IRA limit. Each spouse can potentially contribute up to the annual IRA maximum to their own IRA.
- Traditional or Roth: A spousal IRA can be either type. The spousal part is about eligibility, not account design.
The earned income rule
Normally, to contribute to an IRA you need earned income (also called compensation). That includes wages, salaries, tips, and self-employment income. It generally does not include investment income like interest or dividends.
Spousal IRA rules allow a couple filing jointly to use the working spouse’s earned income to cover contributions for both spouses.
Quick eligibility checklist
- You must be married.
- You must file a joint federal tax return.
- The couple must have enough earned income to cover the total IRA contributions made for both spouses.
- Each spouse must have their own IRA (in their own name).
If you file Married Filing Separately, the spousal IRA door mostly closes and the Roth IRA rules get especially restrictive. For most couples aiming to use spousal IRA rules, filing jointly is the key that unlocks the benefit.
Contribution limits
IRA contribution limits apply per person, per year. The power move with spousal IRAs is that a one-income household can sometimes contribute to two IRAs.
How much can you contribute?
The annual limit is set by the IRS and can change year to year. The simplest way to think about it:
- Each spouse can contribute up to the annual IRA maximum to their own IRA, as long as the couple’s combined earned income is at least that total amount.
- If either spouse is age 50 or older, that spouse may be eligible for an additional catch-up contribution.
Example: Jordan earns $90,000. Casey stays home with the kids and has no earned income. If the annual IRA max were $7,000 per person, they could potentially contribute $7,000 to Jordan’s IRA and $7,000 to Casey’s IRA in the same year, assuming they meet other Roth or deduction rules.
One important limitation: you cannot contribute more than the couple’s total earned income for the year across both IRAs combined.
Stay-at-home vs low-income
In practice, the spousal IRA rules help in two common situations.
Scenario A: stay-at-home spouse
This is the classic spousal IRA setup. The non-working spouse can still have an IRA funded, because the couple’s joint earned income covers it.
- Big win: Retirement savings stays “two-player,” which can improve long-term household security.
- Ownership win: The stay-at-home spouse builds assets in their own name.
Scenario B: low-income spouse
If the spouse has some earned income, they may not even need the spousal rule to contribute, but the spousal rule can still matter because it allows the couple to look at earned income as a household pool when filing jointly.
One nuance: each spouse’s contribution to their own IRA generally cannot exceed their individual earned income unless you are using the spousal IRA framework via a joint return. In other words, filing jointly is what lets a low-income spouse contribute up to the annual maximum even if their own earnings are smaller, as long as the household earned income supports the total.
Scenario C: gap year
Spousal IRAs are also useful when someone takes time off for caregiving, a layoff, going back to school, or moving for a partner’s job. If you still file jointly and one spouse has enough earned income, you can often keep contributions going for both.
Roth vs traditional
This is not just “Roth versus traditional” in general. The spousal wrinkle is that one spouse may not have wages, and that can affect both your current tax situation and your future flexibility.
When Roth often fits
- Your tax bracket is relatively low right now because you are a one-income household or the lower-income spouse stopped working.
- You want flexibility later since Roth contributions (not earnings) can generally be withdrawn tax-free and penalty-free if you follow the rules.
- You expect higher income later when the non-working spouse returns to work.
When traditional often fits
- You want a tax deduction now and you qualify to deduct it.
- You expect a lower tax rate in retirement than today.
- You need to reduce taxable income to qualify for other benefits (this is situational, but it comes up).
The catch: workplace plans
Here is the spousal-specific landmine: if either spouse is covered by a workplace retirement plan (like a 401(k), 403(b), or 457), the ability to deduct a traditional IRA contribution can be limited based on your income. Even if the spouse contributing to the traditional IRA is not personally covered at work, the deduction rules can still change when the other spouse is covered.
One important clarification that helps a lot of middle-income couples: the IRS uses different MAGI phase-out ranges depending on who is covered by a workplace plan. If the spouse making the IRA contribution is not covered by a workplace plan, the deduction phase-out is typically much higher than it is for someone who is covered. That means a stay-at-home spouse (or a spouse without a workplace plan) may still be able to fully deduct a traditional IRA contribution even when the working spouse has a 401(k), depending on your MAGI.
Translation: a traditional spousal IRA contribution may be allowed, but it might be non-deductible depending on your modified adjusted gross income and workplace plan coverage. That is not necessarily “bad,” but it adds paperwork and can change which type is best for you.
How to coordinate accounts
Spousal IRAs shine when you coordinate them with whatever workplace plans are available. Here is a simple priority order many households use, with a few real-world notes.
Step 1: Get the match
If the working spouse has a 401(k) match, treat it like part of your paycheck. Contribute enough to get the full match before you prioritize extra investing elsewhere.
Step 2: Pick the next best dollar
After the match, many couples compare:
- 401(k) fees and investment options
- Whether you want Roth or pre-tax contributions
- Whether you want the flexibility of IRAs
Often, IRAs win on flexibility and investment choice. But a solid low-fee 401(k) can be great too.
Step 3: Fund both IRAs
If you can, funding two IRAs (one for each spouse) can be a powerful baseline habit. Then you can go back and increase 401(k) contributions.
If both spouses have plans
Spousal IRA rules matter less if both spouses have strong earned income, but they can still matter in a year where one spouse’s income drops or stops. The coordination question becomes: should you max both 401(k)s, both IRAs, or a mix? The answer usually comes down to fees, match, and whether you are aiming for Roth, pre-tax, or both.
How to open and fund one
This is simpler than it sounds.
- Open an IRA in the spouse’s name at a brokerage, bank, or robo-advisor.
- Choose Roth or traditional based on your tax strategy and eligibility.
- Contribute from any account you want. The money can come from a joint checking account, the working spouse’s account, or the non-working spouse’s account. What matters is that your household has enough earned income for the year and you file jointly.
- Invest the contribution if you opened an IRA at a brokerage. Many people forget this part and accidentally leave cash sitting in the IRA.
- Track your contributions so you do not exceed the annual limits.
Common mistakes
- Assuming it is a joint IRA: IRAs are individual accounts only. Spousal IRA is a rule, not a shared account.
- Filing Married Filing Separately without realizing the tradeoff: This can limit or eliminate Roth IRA eligibility and complicate IRA deductions.
- Overcontributing: If you contribute over the limit, you may face penalties unless you correct it.
- Forgetting the earned income check: Make sure total IRA contributions do not exceed your household earned income for the year.
- Not coordinating with workplace plan coverage: This can lead to assuming a deduction you do not actually qualify for.
Mini FAQ
Can we do this if we are not married?
No. Spousal IRA rules are for married couples filing a joint return.
Can the non-working spouse contribute if they are older?
Yes. Each spouse’s IRA is based on their own eligibility, and the household earned income supports the contribution as long as you file jointly. If the non-working spouse is 50 or older, they may be eligible for a catch-up contribution.
Do we have to contribute the same amount?
No. You can split contributions however you want, as long as each person stays within the annual limit for their own IRA and the household has enough earned income to cover the total.
What if we already max the 401(k)?
You can still potentially fund IRAs on top of that, subject to the IRA contribution rules and, for Roth IRAs, income eligibility.
The bottom line
If one spouse is not earning much or is not earning anything at all, a spousal IRA is one of the cleanest ways to keep retirement saving fair and consistent. The core rules are straightforward: file jointly, have enough earned income as a household, and open the IRA in the spouse’s name.
If you are unsure how workplace plan coverage, MAGI limits, or deduction rules apply to your household, it is worth confirming the details with a qualified tax professional or a fiduciary financial advisor before you file and fund accounts.
