You cannot open a joint IRA with your spouse. Federal law requires every individual retirement account to have exactly one owner tied to one Social Security number, so no bank or brokerage will let two people share the account itself. Couples still have several ways to coordinate retirement savings: funding a separate IRA for each spouse (including a spousal IRA when only one person earns income), naming each other as beneficiaries, and using joint taxable brokerage accounts for money they want to hold together.
Why the Rule Exists
The tax code defines an IRA as a trust “created or organized in the United States for the exclusive benefit of an individual or his beneficiaries.”1Office of the Law Revision Counsel. 26 USC 408 – Individual Retirement Accounts That “an individual” language is the reason joint ownership does not exist. The IRS tracks contribution limits, required distributions, and penalty thresholds per person, and each account reports under a single taxpayer identification number.2Internal Revenue Service. Form 5498 – IRA Contribution Information
Ownership structures familiar from bank accounts, like joint tenancy with right of survivorship, simply are not available for IRAs. If a custodian somehow allowed joint ownership, the account would lose its tax-advantaged status, and the entire balance could become immediately taxable.
The Spousal IRA for One-Income Households
The main workaround for couples with only one paycheck is the Kay Bailey Hutchison Spousal IRA. A working spouse can fund a separate IRA owned by a non-working or lower-earning spouse, as long as the couple files a joint federal return.3Internal Revenue Service. Retirement Topics – IRA Contribution Limits The combined contributions to both spouses’ IRAs cannot exceed the working spouse’s taxable compensation for the year.
The account still belongs entirely to the non-working spouse. That spouse chooses the investments, controls withdrawals, and names their own beneficiaries. The working spouse is only the source of the money. There is no age limit for making contributions to either a traditional or Roth IRA, so couples well into their 70s can keep contributing as long as at least one spouse has qualifying earned income.3Internal Revenue Service.

How Much Each Spouse Can Contribute in 2026
For 2026, each person can contribute up to $7,500 across all of their traditional and Roth IRAs combined. If you are 50 or older, the limit rises to $8,600.3Internal Revenue Service. Retirement Topics – IRA Contribution Limits A married couple where both spouses work could put away up to $15,000 between their two IRAs, or $17,200 if both are 50 or older.
Neither spouse can contribute more than the household’s taxable compensation for the year. Taxable compensation includes wages, salaries, tips, bonuses, commissions, and net self-employment income. It does not include investment income like dividends, interest, or rental profits, and it does not include pension or annuity payments.4Internal Revenue Service. Topic No. 451 – Individual Retirement Arrangements (IRAs) That distinction matters most for couples approaching retirement who have shifted from earned income to investment income.
Income Limits That Affect Couples
Whether you can deduct traditional IRA contributions or contribute to a Roth IRA at all depends on your household income.
Traditional IRA Deduction Phase-Outs for 2026
If you are covered by a workplace retirement plan like a 401(k), the deduction for traditional IRA contributions phases out at these 2026 income ranges:5Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500
- Single filers covered by a workplace plan: $81,000 to $91,000 of modified adjusted gross income.
- Married filing jointly, contributing spouse covered: $129,000 to $149,000.
- Married filing jointly, contributing spouse not covered but the other spouse is: $242,000 to $252,000.
That last category is the one most couples miss. If your spouse has a 401(k) at work but you do not, your ability to deduct your own IRA contribution has its own, much higher, income threshold. Below $242,000 in joint income, you get the full deduction even though you personally have no workplace plan.
Roth IRA Contribution Phase-Outs for 2026
Roth IRAs have a separate set of income limits that determine whether you can contribute at all, regardless of workplace plan coverage. Married couples filing jointly can make a full Roth contribution if their modified adjusted gross income is below $242,000. The contribution phases out gradually and disappears entirely at $252,000.6Internal Revenue Service. 2026 Amounts Relating to Retirement Plans and IRAs Single filers hit the phase-out between $153,000 and $168,000.
Naming Your Spouse as Beneficiary
The closest thing to shared ownership during the account holder’s lifetime is a beneficiary designation. Naming your spouse as the primary beneficiary sends the IRA directly to them at death without going through probate. Every married IRA owner should verify what the custodian has on file, because the beneficiary form controls even if a will says otherwise.
A surviving spouse who inherits an IRA has options no other beneficiary gets. They can roll the inherited funds into their own IRA and treat the money as if it had always been theirs, resetting required minimum distributions based on their own age.7Internal Revenue Service. Publication 590-A – Contributions to Individual Retirement Arrangements (IRAs) They can also keep the account as an inherited IRA and take distributions based on their own life expectancy, or designate themselves as the account owner.8Internal Revenue Service.

Splitting an IRA in Divorce
QDROs do not apply to IRAs. A Qualified Domestic Relations Order is a tool for splitting employer-sponsored plans like 401(k)s and pensions.9Internal Revenue Service. Retirement Topics – QDRO Qualified Domestic Relations Order IRA transfers in divorce are governed by a different provision entirely.
Under the tax code, transferring an IRA interest to a spouse or former spouse under a divorce or separation instrument is not a taxable event. The receiving spouse becomes the new owner, and from that point forward the IRS treats the account as if it had always belonged to them.1Office of the Law Revision Counsel. 26 USC 408 – Individual Retirement Accounts The divorce decree or settlement agreement drives the transfer, and the custodian needs the decree to reference specific accounts and spell out what percentage or dollar amount goes to which spouse.
Getting this wrong can be expensive. If the transfer is not handled as a direct trustee-to-trustee transfer under the divorce decree, the IRS may treat it as a distribution to the original owner. That means income tax on the full amount, and if the owner is under 59½, a 10 percent early withdrawal penalty on top of it. The QDRO penalty exception that protects distributions from employer plans does not extend to IRAs.10Office of the Law Revision Counsel. 26 USC 72 – Annuities, Certain Proceeds of Endowment and Life Insurance Contracts
Community Property States
Even while both spouses are alive and married, state law can create a shared interest in IRA funds that federal law does not recognize. In community property states, contributions made to an IRA during the marriage are often treated as belonging equally to both spouses. A divorce court can then order the account divided regardless of whose name is on it, and the community property interest can affect estate planning if a spouse dies without addressing it. Rules vary by state, and not every state follows community property principles. The practical effect where they apply is that your individually owned IRA may be treated as a shared marital asset in any legal proceeding, even though the IRS sees only one owner.
Joint Brokerage Accounts for Shared Savings
Couples who want true shared ownership and real-time joint control over investments can open a standard taxable brokerage account together. Joint tenants with right of survivorship gives both owners full access and passes the account automatically to the survivor. Tenants in common lets each owner specify their share, which can pass to anyone they name in their estate plan rather than automatically to the co-owner.
The trade-off is taxes. A joint brokerage account offers no tax deferral or deduction. You owe capital gains tax when you sell investments at a profit, and dividends and interest are taxable in the year received. For couples already funding their individual IRAs to the limit, a joint brokerage account is a natural next step for additional savings. It should not replace tax-advantaged accounts.
Planning for Incapacity
Individual ownership creates a real problem when an account holder becomes incapacitated. Because the IRA belongs to one person, the other spouse has no automatic authority to make investment changes, take required distributions, or update beneficiaries. Without advance planning, the only option is going to court to be appointed as a guardian or conservator, which takes time and money.
A durable power of attorney that specifically covers financial accounts solves this. The document should be drafted while both spouses are competent and should explicitly reference retirement accounts. Some custodians have their own power of attorney forms and may not accept a generic one, so it is worth checking with your IRA provider before you need to use it.
