Yes, getting married is a qualifying life event for health insurance. It opens a special enrollment period that lets you sign up for new coverage, add your spouse to an existing plan, or switch plans outside the normal open enrollment window. The exact timeline you have to act depends on whether you’re enrolling through the Marketplace, an employer plan, or a federal employee plan.
How the Special Enrollment Period Works
A qualifying life event (sometimes called a QLE) is any major life change that triggers a window to enroll in or change health insurance outside the annual open enrollment period. Marriage is one of the most common. Others include having a baby, losing existing coverage, or moving to a new state.
The critical detail is the deadline. For Marketplace plans through HealthCare.gov, you have 60 days from your marriage date to select a new plan or make changes to an existing one. For employer-sponsored plans, the window is shorter: 30 days from the date of your marriage. Miss these deadlines and you’ll typically have to wait until the next open enrollment period, which for most people means waiting months.
Marketplace vs. Employer Plan Deadlines
If you’re enrolling through the ACA Marketplace, you or your spouse can pick a plan by the last day of the month and coverage starts the first of the following month. So if you get married on March 10 and enroll by March 31, your new coverage begins April 1.
Employer plans follow a slightly different rule. Your spouse must request enrollment within 30 days of the marriage date. Once that request is properly submitted, the plan must make coverage effective no later than the first day of the first month after the employer receives the request. Federal employees have a wider window for losing or gaining spousal coverage: enrollment changes can be made starting 31 days before and up to 60 days after a change in coverage status.
Who Can Be Added to a Plan
Marriage doesn’t just let you add your new spouse. Under federal special enrollment rules for employer group health plans, several people may become eligible at once:
- Your spouse, if they weren’t already on the plan and are otherwise eligible.
- You, if your spouse already has employer coverage and the plan covers spouses. You can join their plan.
- Stepchildren who become your spouse’s dependents as a result of the marriage, as long as the plan covers dependent children.
This means a marriage can be the mechanism for combining two separate insurance situations into one family plan, or for one previously uninsured partner to gain coverage through the other’s employer.
Documents You’ll Need
Expect to provide proof of your marriage when enrolling. A marriage certificate is the standard document. Some insurers or Marketplace exchanges may accept a marriage license, but the certificate is the safest bet. If you’re enrolling through an employer, check with your HR department about what they require, since processing times for marriage certificates vary by state and county. If your certificate hasn’t arrived yet, ask whether a certified copy of the license will be accepted temporarily.
How Marriage Affects Subsidies
If you’re buying insurance through the Marketplace, getting married can change your eligibility for premium tax credits (the subsidies that lower your monthly cost). Your “household” for subsidy purposes becomes you, your spouse, and any dependents you claim, and your combined income determines whether you qualify.
Through 2025, there’s no hard income cutoff for premium tax credits. Congress temporarily expanded eligibility so that households earning more than 400% of the federal poverty line can still receive credits if they’d otherwise pay too much relative to income. But combining two incomes on a joint return could still reduce or eliminate the subsidy you were receiving as a single person. One important rule: you generally cannot claim the premium tax credit if you file your taxes as “married filing separately.” You’ll need to file jointly to keep the credit.
If either of you had a Marketplace plan with subsidies before the wedding, report the marriage to the Marketplace promptly. Failing to update your household information can result in owing money back at tax time if you received more in credits than you were entitled to.
One Plan or Two: What to Consider
Marriage doesn’t require you to combine onto one health plan. Many couples find it makes sense to stay on separate plans, and it’s worth running the numbers both ways before deciding.
The average total premium for family coverage through an employer was about $23,968 in 2023, roughly $2,000 per month, with employers covering around 73% of that cost. That employer contribution makes a family plan attractive in many cases, but not always. Some employers charge a spousal surcharge, an extra fee on top of regular premiums, if your spouse has access to their own employer coverage but chooses yours instead. About 5% of employers had this surcharge as of 2022.
There’s also the question of out-of-pocket limits. When everyone is on one plan, a single family out-of-pocket maximum caps your total spending for the year. If you split across two plans, each plan has its own out-of-pocket limit, meaning your combined maximum exposure could be significantly higher. On the other hand, if one of you has significant health needs and the other is healthy, separate plans let you tailor coverage. The healthy spouse might choose a lower-cost, higher-deductible plan while the other selects a plan with a broader provider network and lower cost-sharing.
Transitioning Between Plans Without a Gap
If one spouse is dropping individual coverage to join the other’s employer plan, timing matters. You want the new coverage to start before the old coverage ends. Since employer plans typically become effective the first of the month after enrollment is processed, coordinate your old plan’s cancellation to align with that date. If you’re moving from a Marketplace plan to an employer plan, you can cancel the Marketplace coverage effective the day your new plan starts. Don’t cancel the old plan first and enroll later, as that creates a gap where neither of you has coverage.
If marriage also involves moving to a new state, you may have two qualifying life events at once: marriage and a change of residence. Both independently trigger a special enrollment period, so you’ll have flexibility on the Marketplace even if one event’s window is more convenient than the other’s. A move to a new state means you’ll need to enroll in a plan available in your new zip code, since Marketplace plan availability and provider networks are location-specific.
