Starting a new job in 2026 feels like a fresh start until the benefits packet arrives and says health coverage begins after a waiting period. Federal rules under the Affordable Care Act cap that waiting period at 90 calendar days, so an employee hired on October 1, 2026 must be covered no later than December 30, 2026. Many employers choose the first of the month after 30 or 60 days instead, but the legal ceiling is 90 days, and the wait is real money if you get sick, need a prescription refilled, or schedule a procedure in the meantime. Your old coverage usually ends on your last day of work or the last day of that month, which is what creates the gap. Bridging it takes three decisions: which bridge to use (COBRA, Marketplace, spouse's plan, or Medicaid), how to time the start date so no day is uncovered, and how to hand off cleanly when the employer plan begins so you do not pay for two plans. Federal guidance at healthcare.gov and the Department of Labor confirms every deadline below, and this page anchors each one to a concrete 2026 example so you can count your own days.
Most people in this situation fall into one of two groups. The first group leaves one job and starts another within weeks, so the old plan ends and the new plan has not begun. That group has a clear Marketplace SEP because losing employer coverage is a qualifying life event (QLE), and it can also elect COBRA. The second group was already uninsured or on a plan that did not end, then takes a job with a waiting period. Starting a new job alone does not open a Marketplace SEP, so that group relies on Medicaid or CHIP (open year-round), a spouse's plan, a short-term plan, or waiting for the employer plan. State programs such as Medi-Cal in California, AHCCCS in Arizona, BadgerCare in Wisconsin, and MassHealth in Massachusetts accept applications every day of the year. The 2026 rules also matter for money: the enhanced premium tax credits expired on January 1, 2026, so the 400% FPL subsidy cliff is back, and a higher salary at the new job can reduce or end Marketplace help. The steps below sequence the decision so the cheapest legal bridge comes first.
7 Steps to Get Coverage
Common Mistakes That Cost People Thousands
The costliest mistakes when starting a new job in 2026 involve timing, not price:
- Assuming coverage starts on day one. Federal rules allow a waiting period of up to 90 days, so ask HR for the exact effective date before you resign.
- Letting the 60-day window pass. Marketplace SEP and COBRA election both close 60 days after your old coverage ends, and neither can be reopened.
- Skipping COBRA entirely. Electing within 60 days and paying only if you need care is a legal, low-cost safety net for short gaps.
- Keeping the Marketplace plan and subsidy after the employer plan starts. Advance premium tax credits must be repaid if you were eligible for affordable employer coverage.
- Reporting the wrong income. Marketplace subsidies use your projected 2026 household income, including the new salary, so update it to avoid a tax bill on Form 8962.
How the 90-Day Waiting Period Works in 2026
Federal law under 45 CFR 147.116 bars group health plans from imposing a waiting period longer than 90 calendar days once an employee is otherwise eligible. Day one is your eligibility date, and coverage must begin no later than day 91. An employee who becomes eligible on October 1, 2026 must therefore have coverage by December 30, 2026. Employers may set shorter waits, such as the first of the month after 30 or 60 days, and many do. Orientation periods, hours-based eligibility for variable-hour staff, and union plans have their own rules, so confirm the details in your summary plan description. The waiting period also matters for subsidies: during the wait you are not yet eligible for the employer plan, so Marketplace premium tax credits remain available for those months if your income qualifies. Once employer coverage that meets minimum value and costs no more than 9.96% of household income for self-only coverage in 2026 becomes available, subsidy eligibility ends, and you should cancel the Marketplace plan.
COBRA vs Marketplace vs Spouse's Plan: Which Should You Choose?
After leaving a job in 2026, four bridges open, and the right one depends on gap length and health needs. COBRA preserves your old plan at 102% of the full premium, typically $400 to $900/mo for an individual and $1,200 to $2,800/mo for a family in 2026, but its 60-day election window and 45-day first-payment grace make it a cheap safety net for short gaps. ACA Marketplace plans cost less for most enrollees below the 400% FPL subsidy line in 2026, with the trade-off that provider networks may differ from your old plan. A spouse's employer plan often costs less than COBRA and offers a 30-day special enrollment for the loss of other coverage. Medicaid or CHIP costs nothing if 2026 income qualifies and never expires as an option. A practical decision order: Medicaid first, spouse's plan second, Marketplace with subsidies third, and COBRA for gaps under two months, ongoing treatment with an out-of-network specialist, or a deductible you have already met for the year.
Documents That Prove Your Coverage Loss and Income in 2026
Marketplace SEP applications ask for proof because the loss of coverage is what creates eligibility, not the new job itself. A termination letter or COBRA notice from your old employer states the exact last day of coverage, which fixes your 60-day window. Offer letters and pay stubs from the new job matter for a second reason: the Marketplace calculates subsidies from projected 2026 household income, so a start-date salary that is higher than your old one can shrink or remove the premium tax credit. Medicaid and CHIP agencies use current monthly income instead of annual income, so recent pay stubs or an unemployment award letter carry more weight there. Keep copies of everything, because a Marketplace data-matching request can arrive within 30 days and asks for the same paperwork again.
Medicaid and CHIP Eligibility During a Job Change in 2026
Medicaid can be the cheapest bridge when a job change leaves a month or two of low income. In the 40 expansion states plus DC, adults qualify at or below 138% FPL, which is $22,025 for one person and $45,540 for a family of four in 2026. The 10 non-expansion states (Alabama, Florida, Georgia, Kansas, Mississippi, South Carolina, Tennessee, Texas, Wisconsin, Wyoming) set stricter limits for adults, though Wisconsin covers adults through BadgerCare at a lower threshold. State brand names differ: Medi-Cal in California, AHCCCS in Arizona, MassHealth in Massachusetts, HUSKY Health in Connecticut. CHIP covers children at higher incomes in all 50 states and DC, usually 200% to 300% FPL in 2026, and enrollment stays open all year. Medicaid.gov confirms that no Special Enrollment Period is needed, so a parent can enroll children in CHIP on day one of the gap even if the parent uses COBRA.
Frequently Asked Questions
What is the SEP window when I start a new job in 2026?
The Marketplace Special Enrollment Period lasts 60 days from the date your old coverage ends, and you can also select a plan up to 60 days before that date. If your old coverage ends September 30, 2026, your window runs October 1 through November 29, 2026. Starting a new job is not itself a qualifying life event, so the SEP depends on losing your prior coverage. If you were uninsured before the job, you need Medicaid, CHIP, a spouse's plan, or Open Enrollment (November 1, 2026 to January 15, 2027) instead. Healthcare.gov lists the full set of qualifying events.
How long can a new employer make me wait for health insurance?
Federal law caps the waiting period at 90 calendar days, so coverage must begin no later than the 91st day after you become eligible. If you become eligible on October 1, 2026, the latest start date is December 30, 2026. Many employers start coverage sooner, often the first of the month after 30 or 60 days. Ask HR for the exact effective date before your first day, because the waiting period drives how long your bridge coverage must last. Union plans and variable-hour roles can follow different eligibility rules.
How do I document my coverage loss for a Marketplace SEP?
Upload a termination letter from your old employer, a COBRA election notice, or a final pay stub that shows the coverage end date. Healthcare.gov may ask for the document within 30 days of your application, and coverage can be delayed until it arrives. Keep an offer letter from the new job too, because your projected 2026 household income, including the new salary, determines your premium tax credit. Accurate income reporting avoids owing money on Form 8962 after you receive Form 1095-A.
What if I miss the 60-day window between jobs?
Missing the 60-day window ends both the Marketplace SEP and your COBRA election right. Your options become Medicaid or CHIP (open year-round), a spouse's employer plan if its own window is open, a short-term plan, or waiting for the new employer plan to start. ACA Open Enrollment for 2027 coverage runs November 1, 2026 to January 15, 2027, with coverage beginning January 1, 2027 for plans selected by the December deadline. Going without coverage in the meantime leaves you exposed to full medical costs.
Can I get retroactive coverage while waiting for my employer plan?
COBRA is the main retroactive option. If you elect it within 60 days, coverage reaches back to the day your old plan ended, and your first premium is due 45 days after you elect. Marketplace coverage is not retroactive; it starts the first of the month after plan selection. Medicaid can cover medical bills from up to three months before your application month in many states, though some states have waived this rule. Confirm with your state Medicaid agency.
What is the difference between COBRA and Marketplace for a short gap?
COBRA keeps your exact old plan, network, and any deductible you already met, at 102% of the full premium, typically $400 to $900/mo for an individual in 2026. Marketplace plans have new networks and reset deductibles but can cost far less after premium tax credits, if income is under 400% FPL. For a gap under two months, COBRA elected and paid only when you need care is often the best value. For longer gaps, compare Marketplace premiums at healthcare.gov.
Do I qualify for Medicaid between jobs in 2026?
Medicaid uses your current monthly income, not last year's salary. In the 40 expansion states plus DC, a single adult qualifies at or below 138% FPL, which is $22,025 per year in 2026, and a family of four at $45,540. State brands include Medi-Cal, AHCCCS, BadgerCare, and MassHealth. Apply at healthcare.gov or your state agency any day of the year, and see the household-size table on this page for sizes 1 through 8.
What happens to my children's coverage when I change jobs?
Children can keep coverage through COBRA, join a spouse's plan, or enroll in CHIP, which serves families at roughly 200% to 300% FPL in 2026 depending on the state. CHIP enrollment is open all year and often costs little or nothing, even when a parent does not qualify for Medicaid. Once your new employer plan begins, add dependents within its enrollment window, usually 30 days from your eligibility date, or you may wait until the next annual open enrollment.
