Getting married opens a window to combine or change coverage — but it is two different windows of two different lengths, and one of them has a requirement most couples have never heard of.
Two Deadlines, Not One
You have 30 days to add a new spouse to an employer plan and 60 days to enrol together in a Marketplace plan. Both windows start on the wedding date. The 30-day employer deadline is the one people miss, because it is half as long as the Marketplace window most articles mention.
Put the 30-day date in your calendar before the honeymoon rather than after it. Employer plans are not obliged to make exceptions, and “we were away” is not a reason they have to accept.
The Requirement Nobody Mentions
Can we get Marketplace coverage just because we got married? Only if at least one of you already had coverage. The Marketplace marriage special enrollment period requires that one spouse had minimum essential coverage for at least one day during the 60 days before the wedding. If neither of you had any coverage, marriage alone does not open the Marketplace to you and you would wait for open enrollment. There are exceptions if one spouse lived abroad or in a U.S. territory, or is a member of a federally recognised tribe or an Alaska Native.
This surprises people, and it is the single most common reason a marriage special enrollment application is refused. If you are both currently uninsured and planning a wedding, getting one of you covered beforehand — even briefly — preserves the option.
One Plan or Two?
Should we join one plan or keep our own? Run both. Two separate employer plans are sometimes cheaper than one family plan, because many employers subsidise the employee heavily and the spouse barely at all. Compare the total premium plus both deductibles against the family plan’s premium and single family deductible, and check that both of your doctors are in whichever network you pick.
The deductible comparison is the part people skip. Two individual deductibles of $2,000 are not obviously better or worse than one family deductible of $4,000 — it depends entirely on whether the spending lands on one of you or is spread across both.
When the New Coverage Actually Starts
When does coverage start after we add a spouse? For a Marketplace plan chosen under the marriage special enrollment period, coverage starts on the first day of the month after you select the plan, regardless of which day of the month you enrol. Employer plans commonly backdate to the wedding date, but that varies by plan, so confirm the effective date with HR rather than assuming.
If there is a gap, that matters more than it sounds: a prescription refill or an urgent care visit inside the gap is billed to you at full price.
If One of You Is Offered Insurance at Work
Can I get a subsidy if my spouse is offered insurance at work? Possibly. Since 2023 the affordability test for family members looks at the cost of the family premium rather than employee-only coverage. If covering the whole family through that job would cost more than 9.96% of household income in 2026, the family members can qualify for Marketplace premium tax credits instead. This is the fix to what used to be called the family glitch, and a lot of households still assume the old rule.
Marriage also merges your incomes for subsidy purposes, which cuts both ways. Two people who each qualified for a credit separately can find the combined household sits above 400% of the federal poverty level — about $84,600 for a couple in 2026 — where the credit disappears entirely with no taper.

If Either of You Is Self-Employed
A 1099 spouse has no employer plan to be added to, so the choice is between the W-2 spouse’s family coverage and an individual-market plan for one or both of you. That is usually worth pricing properly rather than defaulting to the plan at work, particularly if the employer contributes little toward dependents. Health insurance when you are self-employed →
