Getting Married? How It Changes Your Health Insurance

The 60-day window

Getting married qualifies both spouses for a Special Enrollment Period. You have 60 days from the date of your marriage to enroll in a marketplace plan, switch to a different plan, or add your spouse to your current one. Keep your marriage certificate handy in case the marketplace asks you to confirm the date.

This window applies whether you're already on a marketplace plan, on an employer plan, or currently uninsured. It also applies to your spouse, so you're both free to make changes.

How marriage changes your subsidy

This is where things get tricky. When you marry, the marketplace combines both spouses' incomes into a single household MAGI (modified adjusted gross income). Your household size goes up by one, but your income usually goes up by more.

For a concrete example: say you earn $30,000 as a single person in 2027. That puts you at about 188% of the federal poverty level ($15,960 for one person), which qualifies you for a solid premium tax credit. Now you marry someone who earns $60,000. Your combined household income is $90,000 for two people. The 400% FPL cutoff for a household of two is $86,560 for 2027 coverage. You're above the subsidy cliff, so you lose all premium assistance. Your credit goes from several hundred dollars a month to zero.

Even if the combined income were slightly lower and you stayed just under the cliff, you'd be expected to pay 10.22% of your income for the benchmark Silver plan, so the subsidy would be small unless premiums in your area are high. The enhanced premium tax credits expired after 2025 and were not extended, so for 2027 the subsidy cliff is still in effect: exceeding 400% FPL by even a dollar means you lose all premium assistance. That can mean going from a subsidized premium to paying hundreds of dollars more each month.

One important rule: you cannot file taxes as Married Filing Separately and claim premium tax credits. The IRS requires a joint return. So there's no way to keep your incomes separate for subsidy purposes once you're married.

Employer plan vs. marketplace: which is better?

If one or both of you has access to an employer-sponsored plan, you have a real decision to make. There's no single right answer.

When the employer plan usually wins

• The employer covers a large share of the premium. On average, employers pay about 73% of the premium for family coverage. If adding a spouse costs $200-$400/month out of your paycheck, that could be less than two separate marketplace plans.
• Your combined income puts you above 400% FPL ($86,560 for two people for 2027 coverage). With no subsidy available, employer coverage is almost always cheaper because of the employer contribution.
• You want simplicity. One plan, one network, one set of deductibles. Easier to manage.

When the marketplace might be better

• Your combined income stays below 250% FPL ($54,100 for a household of two). At this level you qualify for cost-sharing reductions on Silver plans, which lower your deductible, copays, and out-of-pocket maximum. Employer plans don't offer CSR.
• The employer plan has a high cost to add a spouse. Some employers subsidize the employee's premium generously but charge near full price to add a dependent. Check the actual payroll deduction for "employee + spouse" before deciding.
• You want separate plans. On the marketplace, each spouse can pick a different plan and metal tier. Maybe one of you needs a Gold plan for frequent specialist visits while the other is healthy and fine with a Bronze plan.

The split strategy

Some married couples do best with one spouse on an employer plan and the other on a marketplace plan. Thanks to the "family glitch" fix that took effect in 2023, a spouse can qualify for marketplace subsidies even if the employee has access to affordable employer coverage, as long as the cost to cover the spouse on that employer plan exceeds 10.22% of household income (the 2027 affordability threshold). This was a major rule change that opened up subsidized marketplace access for a lot of families.

When to keep separate plans

There are a few situations where maintaining separate coverage makes financial sense:

• Different health needs. If one spouse has a chronic condition and the other rarely sees a doctor, a Gold plan for one and a Bronze plan for the other can save money compared to putting both on a mid-tier plan.
• Different provider networks. If your doctors are in different networks, separate plans let each of you stay with your preferred providers.
• HSA eligibility. One spouse on an HSA-eligible plan can contribute to an HSA (up to $4,500 for self-only coverage in 2027) while the other stays on a lower-deductible plan. You get tax-advantaged savings without both of you dealing with high out-of-pocket costs. Since 2026, marketplace Bronze and catastrophic plans count as HSA-eligible.

What to do in the next 60 days

1. Gather both incomes. Estimate your combined household income for the full year of 2027. Include wages, self-employment income, investment income, and any other MAGI sources. This number determines your subsidy.
2. Check the employer plan.Get the exact cost to add a spouse. Look at the premium, deductible, and out-of-pocket maximum for "employee + spouse" coverage. Compare it to the employee-only cost so you know the true price of adding a dependent.
3. Run the marketplace numbers. Ask Norato find plans for your combined income and household size, or go directly to HealthCare.gov (or your state's exchange). Compare the subsidized marketplace premium to the employer plan cost.
4. Look beyond premiums. Compare deductibles, out-of-pocket maximums, and whether your doctors and prescriptions are covered in each option. A plan that costs $50/month less but has a $4,000 higher deductible may not actually save you money.
5. Enroll before the deadline.The 60-day SEP window is firm. If you miss it, you'll have to wait until Open Enrollment (November 1 through January 15 on HealthCare.gov) to make changes for the following year.
