The 60-Day Marriage Special Enrollment Period
Under ACA rules confirmed by healthcare.gov, marriage is a qualifying life event. That gives you and your spouse 60 days from the wedding date to enroll in or change a health plan. Coverage can typically start on the first day of the month after you enroll.
Do not wait until day 55 to start the process. Employer HR departments often require paperwork within 30 days, and documentation requests from the Marketplace can delay your start date if you scramble at the end.
Important 2026 note: A rule proposed in 2025 would have required more enrollees to submit proof of qualifying events before coverage could start. As of early 2026, that requirement has been blocked by a federal court, but verification rules could still change. Gather your marriage certificate before you apply anyway.
Your Four Health Insurance Options After Marriage
Option 1: Join Your Spouse's Employer Plan
If your spouse's employer offers group health insurance and the plan covers dependents, you can add yourself (or your spouse can add you) within the 60-day SEP window. The cost depends entirely on the employer's premium contribution for spouse coverage.
Watch for spousal surcharges. Many large employers charge an extra $50 to $200 per month when the spouse has access to coverage through their own employer. Ask HR about this before enrolling.
Option 2: Keep Your Own Employer Plan and Skip the Switch
Both of you keeping your own plans is often the cheapest path if both employers contribute generously to individual premiums. Compare total annual costs across three scenarios: both keep individual plans, one joins the other's plan, both enroll in a Marketplace plan. The lowest monthly premium is not always the lowest total-cost option once you factor in deductibles and out-of-pocket maximums.
Option 3: Enroll in an ACA Marketplace Plan
If neither of you has employer coverage, or if employer options are unaffordable (defined by the ACA as costing more than roughly 9% of household income for the employee-only tier), you can shop on the Marketplace at healthcare.gov. As a newly married couple, you file jointly and count as a household of two.
The 2026 ACA subsidy structure uses the enhanced tax credits from prior years. Starting in 2026, the expanded premium tax credits that applied from 2021 through 2025 have expired, which means the 400% FPL "subsidy cliff" is back. If your combined household income exceeds 400% of the federal poverty level, you will not qualify for premium tax credits. Plan accordingly.
Option 4: One Spouse on Medicaid, One on Marketplace
If one spouse has very low income, they may qualify for Medicaid. In states that expanded Medicaid, eligibility runs up to 138% of the federal poverty level. The other spouse could enroll in a Marketplace plan with or without subsidies, depending on their income. This "mixed household" scenario is allowed, and the Marketplace will calculate subsidies for the higher-income spouse based on their share of the household income.
Check medicaid.gov for your state's current expansion status.
2026 ACA Income Limits by Household Size
The table below shows the 2026 income ranges that qualify for ACA premium tax credits. Subsidy eligibility for 2026 plans uses the 2026 federal poverty guidelines published by HHS at aspe.hhs.gov.
ACA Premium Tax Credit Income Limits, 2026 (48 Contiguous States and DC)
| Household Size | 100% FPL (minimum) | 400% FPL (maximum) | Notes |
|---|
| 1 | $15,960 | $63,840 | Single person |
| 2 | $21,640 | $86,560 | Most newlywed couples |
| 3 | $27,320 | $109,280 | Couple plus one child |
| 4 | $33,000 | $132,000 | Couple plus two children |
| 5 | $38,680 | $154,720 | Couple plus three children |
| 6 | $44,360 | $177,440 | |
| 7 | $50,040 | $200,160 | |
| 8 | $55,720 | $222,880 | |
| Each additional | +$5,680 | +$22,720 | |
For Medicaid eligibility, the relevant cutoff in expansion states is 138% of FPL. For a household of two, that is approximately $29,863 in 2026.

How Combining Incomes Affects Your Benefits
When you get married, you and your spouse are counted as a single household for most healthcare programs. This can cut both ways.
It helps when:
- You previously earned below 100% FPL as a single person and were ineligible for Marketplace subsidies in some states. Adding a spouse may bring your household income above the 100% FPL floor and make you eligible.
- A two-person household has a higher FPL threshold than a one-person household, so more income is allowed before subsidies phase out.
It hurts when:
- One spouse earned very little and qualified for Medicaid. Adding a higher-earning spouse can lift the combined income above the Medicaid threshold, ending eligibility.
- Both spouses earned near the 400% FPL limit individually. Combined, the household income may exceed the 2026 subsidy cliff.
If you are unsure which category you fall into, check your eligibility at CoveredUSA before the 60-day window closes. The screener takes about two minutes and accounts for household size, combined income, and state of residence.
How to Apply for Health Insurance After Getting Married
Step 1: Gather your documents
You will need:
- Marriage certificate (original or certified copy)
- Social Security numbers for both spouses
- Proof of income: pay stubs, W-2s, or most recent tax return
- Current insurance cards or policy numbers if switching
- Employer HR contact information for both employers
Step 2: Compare all available plans side by side
Before filling out any application, write down the three-scenario comparison: both keep individual employer plans, one joins the other's employer plan, or both go to the Marketplace. For each scenario, note the monthly premium, the annual deductible, and the out-of-pocket maximum.
Step 3: Notify HR within 30 days
If adding a spouse to an employer plan, notify HR immediately. Most employers set an internal 30-day window even though the ACA SEP is 60 days. Missing the employer's internal deadline can mean waiting for the next open enrollment regardless of ACA rules.
Step 4: Apply through the appropriate channel
- Employer plan: Contact HR or your benefits portal directly
- ACA Marketplace: Go to healthcare.gov and create or log into your account, click "Report a life change," and select marriage
- State Marketplace: Some states run their own exchanges (California, New York, Washington, and others). Find your state's exchange through healthcare.gov
- Medicaid: Apply through your state Medicaid agency or through healthcare.gov
Step 5: Confirm coverage start date
After submitting your application, confirm the exact date your new coverage begins. If there is a gap between your old coverage ending and new coverage starting, you may want to ask HR about retroactive coverage or COBRA as a bridge.
Common reasons applications get denied or delayed:
- Marriage certificate not yet issued (apply for it immediately after the wedding)
- Income reported inconsistently between spouses
- Missed HR internal deadline even though ACA SEP was still open
- Choosing a plan but failing to pay the first premium (coverage does not start without payment)
- Submitting documents after the Marketplace verification request deadline
What About COBRA?
If one spouse had employer coverage and is now joining the other's plan, there is no need for COBRA. COBRA is an option when someone loses coverage entirely and needs to continue their existing plan temporarily. At roughly 102% of the full premium, COBRA is expensive. For most newly married couples switching to a joint plan or the Marketplace, COBRA is not the right choice.
The one exception: if you are mid-treatment with a specific doctor or hospital and do not want to risk a coverage gap, COBRA lets you stay on your exact current plan while you finalize your new coverage.
Special Situations
Both spouses have good employer coverage: Keep both individual plans if the employer contributions are strong. You each pay the individual premium rather than a family premium, which is frequently cheaper.
One spouse is self-employed: The self-employed spouse cannot get a tax-deductible employer plan, but can deduct 100% of their health insurance premiums from their federal income taxes if they are not eligible for coverage through their spouse's employer. If eligible for the spouse's employer plan, that deduction disappears.
One spouse is under 26 and on a parent's plan: Marriage does not automatically remove someone from a parent's plan before age 26 unless they choose to leave. You can stay on a parent's plan and your new spouse can get their own coverage independently.
One spouse has a pre-existing condition: The ACA prohibits insurers from denying coverage or charging more for pre-existing conditions on all individual and family plans sold on or off the Marketplace. This protection applies regardless of when you enroll during the marriage SEP.
Frequently Asked Questions
How long do I have to add my spouse to my health insurance after marriage?
You have 60 days from your wedding date to change your health insurance under the ACA Special Enrollment Period rules. Employer plans may have shorter internal deadlines (often 30 days), so check with HR immediately after getting married.
Can my spouse and I be on different health insurance plans?
Yes. You and your spouse can each keep your own employer-sponsored plans, or one can be on an employer plan while the other uses the Marketplace or Medicaid. There is no requirement to be on the same plan.
Does getting married affect my Medicaid eligibility?
Yes. Medicaid counts both spouses' incomes once you are married. If your combined household income exceeds the Medicaid limit for a two-person household (approximately $29,863 in expansion states in 2026), you would lose Medicaid eligibility. You could then apply for an ACA Marketplace plan with a possible subsidy.
Do I qualify for ACA subsidies as a newly married couple in 2026?
As a two-person household in 2026, you qualify for ACA premium tax credits if your combined income is between $21,640 and $86,560. Above $86,560, the 2026 subsidy cliff means no premium tax credits are available.
What documents do I need to apply for the marriage SEP?
You need your marriage certificate, both Social Security numbers, proof of income (pay stubs or tax returns), and information about any current health coverage. The Marketplace may request documentation within 30 days of your enrollment.
What if I miss the 60-day marriage SEP window?
If you miss the 60-day window, you cannot enroll in or change a Marketplace plan until the next open enrollment period, which typically runs from November 1 through January 15 for coverage starting January 1. Employer plans follow their own open enrollment schedules, usually in the fall.
Is getting married a qualifying event for employer health insurance too?
Yes. Marriage is a qualifying life event for employer-sponsored plans as well as ACA Marketplace plans. Most employer plans allow a 30-day or 60-day window to add a spouse or change coverage after marriage.
Can I stay on my parents' health insurance after getting married?
If you are under 26, you can remain on a parent's plan after getting married. Marriage does not end dependent coverage for adults under 26. Your new spouse would need separate coverage, however, as they cannot be added to your parent's plan.
Marriage is one of the few times outside of open enrollment when you can freely change your health insurance setup. Use the full 60-day window, but do not wait until the last week. Gather your marriage certificate, run the three-scenario cost comparison, and lock in coverage before the deadline.
