A new job in 2026 rarely brings health insurance on day one. Federal law under the Affordable Care Act caps the employer waiting period at 90 calendar days, so a worker who becomes eligible on November 2, 2026 must have employer coverage begin no later than January 31, 2027. Until then, the new hire is uninsured unless a bridge plan fills the gap. Starting a job is not a qualifying life event for a Marketplace Special Enrollment Period (SEP), which surprises many people who assume a new employer or a coverage gap automatically opens enrollment. Your bridge options depend on what happened to your prior coverage: COBRA from the old employer, a spouse's plan, Medicaid or CHIP if income is low, a Marketplace plan through a loss-of-coverage SEP or 2027 Open Enrollment, or a short-term plan with real limits. The waiting period also applies to dependents, so a spouse and children face the same gap. This page walks through the 90-day rule, the clocks that start when old coverage ends, and the cheapest way to cover each week of the gap, using 2026 rules from healthcare.gov, dol.gov, and medicaid.gov.
The calendar works in your favor in October 2026. ACA Open Enrollment for 2027 coverage opens November 1, 2026 and HealthCare.gov accepts applications through January 15, 2027, with January 1, 2027 coverage when you enroll by December 15, 2026. Many November hires can therefore buy a Marketplace plan for January 1 and need a short bridge only for November and December, such as COBRA or a short-term plan. Hires whose prior coverage ended in 2026 hold a separate 60-day Marketplace SEP. The core trade-off is cost against risk: one unplanned emergency room visit can exceed several months of premiums, and the 2026 out-of-pocket maximum for Marketplace plans is $10,600 for an individual. Once employer coverage begins, a Marketplace plan with premium tax credits generally must end, and credits received for months you were eligible for affordable employer coverage are repaid when you file Form 8962 with your 1095-A. Plan affordability and minimum value decide whether you keep subsidies after your new employer plan starts.
7 Steps to Get Coverage
Common Mistakes That Cost People Thousands
Workers bridging a new-job waiting period make these costly errors in 2026:
- Assuming the new job opens a Marketplace SEP. Starting work is not a qualifying life event, so only a loss of prior coverage or Open Enrollment lets you buy a plan.
- Letting the 60-day COBRA and SEP clocks run while waiting for HR. Both windows start on your last coverage day, not on your first paycheck.
- Skipping bridge coverage entirely. One 2026 emergency visit can cost more than the 90-day gap in premiums.
- Keeping Marketplace premium tax credits after employer coverage starts. Credits for months you could have enrolled in affordable employer coverage must be repaid on Form 8962.
- Buying a short-term plan without reading the exclusions. Short-term plans can deny pre-existing conditions and skip essential health benefits.
- Forgetting the employer enrollment deadline. Most plans give 30 days after your eligibility date, and missing it can mean waiting for the next employer open enrollment.
How the 90-Day Employer Waiting Period Rule Works in 2026
Federal ACA rules, codified at 29 CFR 2590.715-2708 and enforced by the Department of Labor, prohibit any group health plan from imposing a waiting period longer than 90 calendar days. The clock counts every day including weekends and holidays, and the plan may not extend it because day 90 lands on a Saturday. A waiting period begins on the date you meet the plan's eligibility conditions, such as full-time status or a job category, and an employer may require a reasonable orientation period of up to one month before that clock starts. For a worker eligible on November 2, 2026, the latest legal coverage start is January 31, 2027. Plans that tie eligibility to hours worked, such as a 130-hour monthly threshold for variable-hour employees, follow separate measurement-period rules that can run longer. Many employers start coverage on the first of the month after 30 or 60 days, so ask HR which rule applies to you and whether the dependents' coverage starts the same day. The dol.gov ACA FAQ Part IV and healthcare.gov both publish the official language.
COBRA vs Marketplace vs Spouse's Plan vs Short-Term Plan: Which Should You Choose in 2026?
After leaving a prior employer, four pathways bridge the new-job waiting period in 2026. COBRA preserves your old plan at 102% of the full premium in 2026, typically $400 to $900/mo for an individual and $1,200 to $2,800/mo for a family, and it is retroactive, so you can elect it only if you actually need care. Marketplace plans bought through the 60-day SEP or 2027 Open Enrollment often cost less in 2026 once premium tax credits apply, though you may change providers and your plan starts the first of the month after selection. A spouse's employer plan frequently beats both on price if your spouse's employer offers a 30-day special enrollment. Short-term limited-duration plans cost less per month but sit outside ACA protections, and the 2024 federal rule capping them at 4 months total has had enforcement paused since August 2025 while the agencies rewrite it, so state law decides what you can buy. The practical order for 2026: Medicaid or CHIP first if income qualifies, then a spouse's plan, then a Marketplace plan with subsidies, then COBRA for the shortest necessary stretch, and a short-term plan only for a healthy adult with a gap of a few weeks.
Medicaid and CHIP During the Waiting Period in 2026
Medicaid eligibility turns on current monthly income, so a new employee still waiting on employer coverage may qualify even with a salary offer on file. In the 40 expansion states plus DC, the 2026 limit is 138% of the Federal Poverty Level, or $22,025 for one person and $45,540 for a family of 4 in 2026. State programs go by local brands: California's Medi-Cal, Arizona's AHCCCS, Massachusetts's MassHealth, Wisconsin's BadgerCare, Connecticut's HUSKY Health, and New Jersey's NJ FamilyCare. Ten states (Alabama, Florida, Georgia, Kansas, Mississippi, South Carolina, Tennessee, Texas, Wisconsin, Wyoming) have not expanded Medicaid, leaving a coverage gap for adults below 100% FPL in 2026. Children often qualify for CHIP at household incomes of 200% to 300% FPL in 2026 even when parents do not, and CHIP enrollment runs year-round. Apply at healthcare.gov or your state agency listed on medicaid.gov, and report the new salary when your employer coverage starts so the state can end or coordinate benefits.
Frequently Asked Questions
What is the longest waiting period an employer can require for health insurance?
Federal ACA rules cap the employer waiting period at 90 calendar days from the date you become eligible, with no extension for weekends or holidays, per the Department of Labor at dol.gov. A worker eligible on November 2, 2026 must have coverage begin by January 31, 2027. Employers may add an orientation period of up to one month before the clock starts, and variable-hour employees follow separate measurement-period rules. Many employers start coverage sooner, on the first of the month after 30 or 60 days, so ask HR for the exact written start date.
Does starting a new job give me a Special Enrollment Period?
Starting a new job is not a qualifying life event, so it does not open a Marketplace Special Enrollment Period by itself. A loss of prior coverage does: you have a 60-day window from the last day of your old plan to enroll at healthcare.gov, and you can apply up to 60 days before it ends. Without a loss of coverage, you wait for 2027 Open Enrollment, which begins November 1, 2026. Medicaid and CHIP remain open year-round regardless of the job change.
How do I document the coverage gap for a Marketplace SEP?
Upload a termination letter, COBRA notice, or insurer letter showing the last day of your prior coverage when healthcare.gov requests proof. The Marketplace usually asks for documents within 30 days of your application. Keep your offer letter with the hire and eligibility dates, plus pay stubs or the offer salary to estimate 2026 income. If you were uninsured before the job, no document can create an SEP, so plan around Open Enrollment or Medicaid instead.
What if I miss the 60-day SEP window after my old coverage ended?
Missing the 60-day Marketplace SEP means you cannot buy a Marketplace plan until Open Enrollment, which starts November 1, 2026 for 2027 coverage and runs through January 15, 2027 on HealthCare.gov. Enroll by December 15, 2026 for a January 1, 2027 start. Your employer plan may start before then, which ends the problem. Medicaid and CHIP stay available year-round, and COBRA has its own 60-day election window that also ends if missed.
What is the difference between COBRA and Marketplace for bridging a waiting period?
COBRA keeps your old plan, doctors, and met deductible at 102% of the full premium in 2026, about $400 to $900/mo for an individual, and it is retroactive to the day coverage ended. Marketplace plans start the first of the month after you choose them and may cost less after 2026 premium tax credits, but networks differ. For a gap under two months, COBRA elected only after a claim can be cheaper. For three months or more, a subsidized Marketplace plan usually wins.
Can I get retroactive coverage during a new-job waiting period?
COBRA is the main retroactive option: coverage reaches back to the day your old plan ended once you elect and pay within the 60-day and 45-day deadlines. Marketplace plans are not retroactive and start the first of the next month. Employer plans do not cover care before the waiting period ends. Many state Medicaid programs, such as Medi-Cal and MassHealth, can cover medical bills from up to 3 months before your application month in 2026 if you met the income rules then.
Do I qualify for Medicaid while waiting for my employer plan?
Medicaid looks at your current monthly income, so you may qualify during the waiting period. In expansion states the 2026 limit is 138% FPL, $22,025 for one person and $45,540 for a family of 4, as shown in the household-size table above. Apply at healthcare.gov or your state agency such as Medi-Cal, AHCCCS, or BadgerCare. Report your new salary and the employer coverage start date so the state can end or coordinate benefits.
What happens to my children's coverage during the waiting period?
Children face the same employer waiting period as you, but they often qualify for CHIP at household incomes of 200% to 300% FPL in 2026, even when adults do not qualify for Medicaid. CHIP enrollment is year-round, and premiums are low or zero. Your children also qualify for the Marketplace SEP if their prior coverage ended. Add dependents to the employer plan within its enrollment window, usually 30 days after your eligibility date, or you wait for the next employer open enrollment.
