The Health Insurance Waiting Period at a New Job, and How to Cover the Gap

How long a new employer can make you wait

Under the Affordable Care Act, a group health plan cannot make an eligible employee wait more than 90 days for coverage to begin. The count is in calendar days, not business days, so weekends and holidays count toward the 90.

A few details change the math:

• The clock starts when you become eligible, which for most full-time hires is the first day of work.
• An employer may add an orientation period of up to one month before the 90-day waiting period begins, if it is a genuine part of onboarding. In that case the wait can run about four months.
• If your hours vary, the employer may use a measurement period to decide whether you count as full time before you are eligible at all. That can take considerably longer than 90 days.
• Many employers use a shorter wait, such as coverage beginning the month after 30 or 60 days of work. Some cover new hires from day one.

The 90-day rule sets a maximum, not a standard. Your plan's own wait is in the benefits packet.

Why the gap is often longer than it looks

The gap begins when your old coverage ends, not on your new start date. Some plans run to the end of the month you leave; others stop on your last day. Then add the new plan's wait.

Say you leave your old job on March 10, and that coverage ends March 31. You start the new job March 17, and its plan begins the month after 60 days of work, which is June 1. All of April and May are uncovered.

Five questions to ask your new HR department

1. On exactly what date does my coverage begin?
2. Is there an orientation period before the waiting period starts?
3. Am I classified as full time, part time or variable hour?
4. Can my spouse and children be covered on the same date?
5. What will the plan cost per paycheck, and what is the deductible?

Then get your old plan's end date in writing.

Option 1: COBRA from your old job

If your old employer had 20 or more employees, you can usually keep the same plan under federal COBRA, and many states have similar continuation rules for smaller employers. You pay the full premium plus up to a 2 percent fee. That surprises people who only ever saw the employee share.

Two COBRA rules matter for a short gap:

• You have 60 days to elect, counted from the later of the date your coverage ends or the date you receive the election notice.
• Once you elect and pay, coverage is retroactive to the day your group plan ended. Your first payment is generally due within 45 days of electing.

Because of that, some people with a short, predictable gap hold the COBRA election as a backup and elect only if they need care. That carries real risk: a doctor or pharmacy may ask you to pay up front while your coverage shows as inactive, and missing a deadline ends the option for good. If you are in treatment, take regular prescriptions or have already met this year's deductible, simply electing COBRA is usually the cleaner choice. The COBRA alternatives page compares it with the other paths.

Option 2: A Marketplace plan through special enrollment

Losing job-based coverage opens a 60-day special enrollment period on the Marketplace, and you can apply up to 60 days before the loss as well. A Marketplace plan must accept you regardless of health and covers pre-existing conditions. If you pick a plan before your old coverage ends, the Marketplace plan generally begins at the start of the month after the loss, which avoids a gap when your old plan ends on the last day of a month.

You can end the Marketplace plan when the employer plan takes effect. If you elect COBRA first, you can still switch to the Marketplace within that original 60-day window, but voluntarily dropping COBRA later does not open a new one.

How a job offer affects Marketplace financial help

The premium tax credit is not available for months when you are eligible for employer coverage that counts as affordable and meets minimum value. During a waiting period you are not yet eligible for the job's plan, so a Marketplace plan for those months can still qualify for help. The credit is based on your expected household income for the whole year, and that includes the new salary, which can push some households over the 2027 limit of 400 percent of the federal poverty level. Once the employer plan is available and affordable, the credit stops even if you turn the job's plan down. Report the new coverage to the Marketplace and end the Marketplace plan on the day the employer plan begins, so you do not pay for two plans or receive credit you may have to repay. General information, not tax advice — confirm with your CPA based on your specific entity structure.

Option 3: A private plan for the gap

A private, medically underwritten plan is another route, especially if you are healthy and your household income will land above the subsidy line.

• You can apply year-round, without a special enrollment period.
• If approved, coverage can start on the first of the month after your old plan ends.
• Approval depends on your health answers, and pre-existing conditions may be excluded.
• Benefits vary by plan, and private plans are not Marketplace plans.
• You can cancel it once your employer plan takes effect. Ask how cancellation works before you apply so the dates line up.

Keep your COBRA election window open while the application is reviewed. It is your fallback if underwriting does not go your way.

What about short-term plans?

Short-term plans are often marketed for exactly this kind of gap. I do not sell them. They do not have to follow ACA rules and often exclude pre-existing conditions. If you are considering one, read short-term health insurance first so you know what they do and do not cover.

Matching the bridge to your situation

• Healthy, no regular prescriptions, gap of a month or two. Compare a private plan with a Marketplace plan, and keep COBRA as the backup.
• In treatment, pregnant or managing a chronic condition. COBRA or a Marketplace plan, since both accept you regardless of health. COBRA keeps your current doctors.
• New salary below the subsidy line. A Marketplace plan with financial help for the waiting months is often the most affordable bridge.

Once the employer plan begins, it is usually the better deal, because the employer pays part of the premium.

A simple example

Dana, 38, leaves her job on August 15, and her old coverage ends August 31. She starts her new job September 2, and its plan begins November 1, after a 60-day wait. That leaves September and October uncovered. She is healthy, takes no regular prescriptions, and her new salary puts her above the subsidy line. She applies for a private plan that, if approved, starts September 1, and she keeps her COBRA election window open. If she is approved, she cancels the private plan effective October 31. If she is not, she elects COBRA, which reaches back to September 1.
