Getting married sets off a legal countdown that most couples do not notice until it is almost too late. Under the Affordable Care Act, marriage is one of the recognized qualifying life events that triggers a Special Enrollment Period outside of the regular November-to-January Open Enrollment window. The 60-day SEP starts the day of the wedding, not the day you get around to reading the fine print. Two distinct clocks run simultaneously: 60 days for the ACA Marketplace SEP and 30 days for adding a spouse to an employer plan. Letting the shorter employer-plan window expire while waiting to decide is the most common and most expensive mistake newlyweds make. The right path depends on three variables: whether either spouse has employer coverage available, your combined Modified Adjusted Gross Income (MAGI), and whether at least one of you had prior coverage in the 60 days before the ceremony. Tax filing status matters too: married couples who file taxes as married-filing-separately are disqualified from ACA premium tax credits in most cases. Getting this right in the first weeks of marriage can save thousands of dollars annually in 2026, because the enhanced ARPA and IRA subsidy rules expired on January 1, 2026, and the 400% FPL subsidy cliff has returned, making plan selection and income reporting more consequential than during the prior four years.
Four coverage paths open immediately after the wedding. The employer-plan path usually produces the cheapest monthly premium when one spouse's employer subsidizes a family or spouse-and-employee plan heavily. The Marketplace SEP path uses your combined MAGI to calculate premium tax credits on healthcare.gov or your state's exchange. Medicaid is the best choice if combined income falls under 138% of the Federal Poverty Level, roughly $29,863 for a household of 2 in 2026 per HHS ASPE guidelines, and you live in one of the 40 Medicaid expansion states plus DC. COBRA continuation from a prior plan is almost always the most expensive path and is worth considering only if you are mid-treatment with a specialist not available in any available network. For most newlyweds, the priority order is: check Medicaid first, then employer plan, then Marketplace with subsidies, then COBRA as a last resort. The sections below walk through each step in detail. If you are unsure how the ACA income limits work for 2026, the Medicaid income limits and ACA income limits pages provide the full lookup tables you need.
7 Steps to Get Coverage
Common Mistakes That Cost People Thousands
The costliest mistakes couples make with health insurance in the weeks after getting married:
- Missing the 30-day employer plan window while focused on the 60-day Marketplace SEP. Employer plan deadlines run from the wedding date and do not extend. Missing the 30-day window means waiting for the employer's next annual Open Enrollment, which could be six to twelve months away.
- Not knowing about the prior-coverage requirement. The ACA Marketplace marriage SEP requires at least one spouse to have had minimum essential coverage for at least one day in the 60 days before the wedding. Couples who were both uninsured before the ceremony do not qualify for the Marketplace SEP.
- Reporting only one spouse's income on the Marketplace application. After marriage, combined household MAGI determines subsidy eligibility. Reporting only one spouse's income produces an incorrect subsidy and a potential IRS reconciliation bill or overpayment at the end of the year on Form 8962.
- Choosing married-filing-separately on your tax return. Married-filing-separately disqualifies you from ACA premium tax credits in most cases. File jointly to preserve access to the premium tax credits and the marketplace SEP subsidy benefits.
- Defaulting to COBRA because it feels familiar. COBRA charges 102% of the full employer-plus-employee premium, often $700 to $2,000 per month for an individual and $1,500 to $2,800 per month for two people. An ACA Marketplace plan with subsidies is almost always cheaper after a household income recalculation following marriage.
The Prior-Coverage Requirement: What Counts and What to Do If Neither Spouse Qualifies
Federal rules for the ACA Marketplace marriage Special Enrollment Period require that at least one spouse had minimum essential coverage (MEC) for at least one day during the 60 days before the wedding date. Qualifying prior coverage includes any employer-sponsored plan, Medicaid, Medicare, CHIP, a Marketplace plan, or coverage through a parent's plan under the ACA dependent coverage rule (valid until age 26). Short-term limited-duration plans and health-sharing ministries do not count as minimum essential coverage and do not satisfy this requirement.
Couples who both lacked qualifying coverage before the wedding still have two paths. Medicaid has no prior-coverage requirement and is year-round in all 50 states plus DC for households meeting income thresholds. In expansion states, a household of 2 with combined income under approximately $29,863 (138% FPL for 2026) qualifies regardless of prior coverage history. The second path is waiting for the next ACA Open Enrollment Period (November 1 to January 15, 2027 for 2027 coverage). Couples in this situation should also check whether their employer offers a general open enrollment period that would cover both spouses.
How Combining Households Changes Your 2026 ACA Subsidy
Marriage changes your household size from 1 to 2 and requires combined MAGI reporting. For 2026, the ACA Marketplace uses the 2025 federal poverty guidelines as the income reference for premium tax credit calculations. Combined household income is compared against those guidelines to determine your premium tax credit. The 2026 subsidy cliff at 400% FPL (approximately $86,560 for a household of 2 based on 2025 FPL) means couples with combined income above this level receive no premium tax credits, a change from the enhanced ARP and IRA rules that expired January 1, 2026.
The family-glitch fix that took effect in 2023 added a separate affordability test for family members. Under this rule, if the lowest-cost employee-plus-family premium at your employer exceeds approximately 9.96% of your combined household MAGI, your spouse can purchase a subsidized Marketplace plan even if your self-only employer coverage is considered affordable under the old single-person test. Check healthcare.gov's subsidy calculator with your actual household numbers to see whether this helps. Cost-sharing reductions on Silver plans are available for households between 100% and 250% FPL (approximately $22,310 to $55,760 for a household of 2 in 2026), providing additional savings beyond the premium tax credit.
Documents You Need to Enroll After Getting Married
Both the ACA Marketplace and most employer benefit offices require documentation to verify a qualifying life event before activating a Special Enrollment Period. Gathering these in advance prevents delays that can push enrollment past the 60-day or 30-day deadline.
- Marriage certificate or marriage license (official certified copy showing ceremony date and issuing county or state)
- Proof of prior minimum essential coverage for at least one spouse: insurance member card with coverage dates, HIPAA certificate of creditable coverage, a 1095-A, 1095-B, or 1095-C form, or a termination letter from a prior insurer showing coverage ended within the past 60 days
- Social Security numbers for both spouses
- Proof of current address for both spouses (utility bill, lease agreement, or government-issued ID with matching address)
- Immigration documents if either spouse is a lawfully present non-citizen (Form I-551, I-94, current visa, or Employment Authorization Document)
Frequently Asked Questions
What is the SEP window for getting married?
Marriage triggers a 60-day Special Enrollment Period on the ACA Marketplace starting on your wedding date. For example, if you married on June 15, 2026, your Marketplace SEP window runs through August 14, 2026. The employer plan window is shorter at 30 days from the wedding date. Medicaid has no SEP deadline and accepts applications year-round in all 50 states plus DC.
Does one spouse need to have had health insurance before the wedding to use the marriage SEP?
Yes, for the ACA Marketplace SEP. At least one spouse must have had minimum essential coverage (any qualifying health plan) for at least one day during the 60-day period before the wedding. Qualifying coverage includes employer-sponsored plans, Medicaid, Medicare, CHIP, and ACA Marketplace plans. Short-term limited-duration plans and health-sharing ministries do not qualify. If neither spouse had prior coverage, you cannot use the Marketplace marriage SEP; apply for Medicaid if income qualifies, or wait for November Open Enrollment.
How do I document the marriage for the SEP application at healthcare.gov?
Healthcare.gov and most employer plans require an official certified copy of your marriage certificate or marriage license, showing the ceremony date and the issuing county or state. You also need proof of prior minimum essential coverage for at least one spouse, such as an insurance card with coverage dates, a HIPAA certificate of creditable coverage, a 1095-A, 1095-B, or 1095-C tax form, or a termination letter from a prior insurer. Healthcare.gov may accept a self-attestation for up to 90 days if you are waiting for the certificate from the county clerk.
What if I miss the 60-day marriage SEP window?
Missing the 60-day Marketplace SEP typically means waiting until the next ACA Open Enrollment Period, which runs November 1 to January 15, 2027 for coverage starting January 1, 2027. You can still apply for Medicaid year-round with no deadline if combined income qualifies. Going without coverage in the gap is risky: a single emergency room visit without insurance can cost $3,000 to $10,000 or more out of pocket.
Can my new spouse get retroactive coverage from the wedding date?
Retroactive coverage to the wedding date itself is not standard for the ACA Marketplace marriage SEP. Coverage typically starts the first day of the month after you enroll, or the first of the following month if you enroll after the 15th. Employer plans vary, with some making coverage effective the date of the qualifying event and others starting on the first of the next month. Check with your employer's HR department for the exact effective date rule.
How does getting married change my ACA subsidy eligibility in 2026?
Marriage requires you to report combined household MAGI on your Marketplace application. A spouse with a high income can push combined MAGI above 400% FPL (approximately $86,560 for a household of 2 in 2026), which eliminates all premium tax credits because the enhanced ARPA and IRA subsidies expired January 1, 2026, and the subsidy cliff is back. You must also file taxes jointly to access premium tax credits; married-filing-separately disqualifies you in most cases. Conversely, if both spouses had low individual incomes, combining into one household of 2 may increase subsidies.
What state-specific rules apply for adding a spouse to health insurance after marriage?
Employer plan rules are governed by ERISA and IRS regulations at the federal level, meaning the 30-day qualifying event window applies in all states. For Medicaid, state rules vary significantly: the 40 expansion states plus DC cover households of 2 under 138% FPL (about $29,863 in 2026), while the 10 non-expansion states have much stricter rules. State-named Medicaid programs include Medi-Cal (California), AHCCCS (Arizona), MassHealth (Massachusetts), Apple Health (Washington), BadgerCare (Wisconsin), and HUSKY Health (Connecticut). Some states have state-only programs that supplement federal Medicaid for lawfully present non-citizens, so check your specific state's agency if immigration status is a factor.
Can my spouse and I qualify for Medicaid after getting married?
Yes, if your combined 2026 household income is under 138% of the Federal Poverty Level for a household of 2 (approximately $29,863 in expansion states per HHS ASPE 2026 guidelines). Apply through healthcare.gov or your state Medicaid agency year-round with no SEP deadline. In the 10 non-expansion states, the income threshold is much lower and most non-disabled adults do not qualify for Medicaid. CHIP is also available for children in your household at higher income levels (typically 200 to 300% FPL) regardless of whether you personally qualify for Medicaid.
