Switching jobs is one of the most common health insurance gaps in the United States, affecting millions of workers every year. The transition looks simple on paper: old job ends on Friday, new job starts Monday. But health coverage rarely works that cleanly. Most employer plans end on the last day of employment or the last day of the month, and most new employer plans have a 30 to 90 day waiting period before coverage begins. That gap, even if it is only a few weeks, is when something expensive can happen. The ACA's Loss-of-Coverage Special Enrollment Period exists to protect you during exactly this scenario. Under federal law, losing job-based coverage is a qualifying life event that opens a 60-day window to enroll in either an ACA Marketplace plan or your new employer's plan if that plan allows mid-year enrollment for new hires. The key is acting within that window. Waiting it out without coverage is legal but risky, and missing the 60-day SEP after your old coverage ends could leave you uninsured until November's Open Enrollment if your new employer's waiting period extends past the SEP deadline.
Job switching in 2026 comes with one important change from prior years: ACA premium tax credits are less generous than they were in 2021 through 2025. The enhanced premium tax credits from the American Rescue Plan Act and the Inflation Reduction Act expired on January 1, 2026, meaning the 400% FPL subsidy cliff is back. For a single person with income above $63,840 in 2026, Marketplace subsidies drop to zero. For workers switching to higher-paying jobs, this changes the Marketplace math. For workers with a temporary income gap or stepping into a lower-salary role, the ACA income limits are still relevant. Check the ACA income limits to see whether your transition-year income qualifies for premium tax credits. Medicaid income limits also apply year-round for those with a genuine income drop during the gap. This guide walks through the four options in order of likelihood, with the exact 60-day window math, documents you will need, and the mistakes that cost people coverage.
7 Steps to Get Coverage
Common Mistakes That Cost People Thousands
The most costly mistakes people make when switching jobs and bridging health coverage in 2026:
- Assuming the new employer plan is automatic. Most new employer plans require you to actively enroll within 30 days of your start date. Missing that window usually means waiting until the employer's next annual open enrollment.
- Defaulting to COBRA without comparing Marketplace. COBRA costs 102% of the full premium. A 45-day Marketplace bridge plan often costs under $100 per month after subsidies for workers with lower transition-year income, making COBRA the worst financial choice for most people.
- Using your old salary for Marketplace subsidy estimates. The Marketplace uses projected 2026 income for subsidy calculations. During a job gap, your projected income may be lower than your old salary, which means larger subsidies. Use the income you will actually earn for the remainder of the year.
- Not verifying the exact coverage end date. Some employer plans end on the last day of the month even if you leave mid-month, which can delay the SEP start date and give you more time. Others end on your last day of work. Call HR to confirm before making any decisions.
- Going uninsured during a short gap. A weekend without insurance might seem low-risk, but a single emergency room visit can generate a $5,000 to $30,000 bill. A 30-day short-term Marketplace plan or even enrolling in COBRA retroactively within 60 days costs far less than one uninsured hospitalization.
- Forgetting about children. Even if you bridge the gap yourself with COBRA, children may qualify for CHIP at incomes up to 200-300% FPL depending on your state. CHIP enrollment is year-round and far cheaper than adding children to COBRA.
COBRA vs ACA Marketplace vs New Employer Plan: Which Should You Choose?
Job-switching coverage decisions in 2026 come down to three variables: how long the gap is, what your transition-year income looks like, and whether your ongoing medical needs are tied to a specific provider or specialist. COBRA preserves your old plan's network at 102% of the full premium. For a typical individual, that runs $500 to $1,200 per month in 2026. For a family plan, expect $1,500 to $2,800 per month. COBRA's only advantages are zero network disruption (your current doctors and in-progress treatments continue) and retroactive activation (you can elect COBRA after the fact up to 60 days, backdating coverage to when your old plan ended). Those advantages are rarely worth $1,500 per month unless you have a specific ongoing treatment with an out-of-network specialist.
ACA Marketplace plans through healthcare.gov are the best bridge option for most workers with a gap of 30 days or more and income under $63,840 in 2026 (400% FPL for a single person). Marketplace plans for bridge coverage can be enrolled on a month-by-month basis: enroll under the Loss-of-Coverage SEP, use the plan during the gap, then terminate when your new employer coverage begins. Premium tax credits are recalculated at tax time using your actual annual income via Form 1095-A and IRS Form 8962. For higher-income workers (above the 400% FPL cliff), the ACA Marketplace offers no subsidy and plans can cost $400 to $800 per month unsubsidized. In that scenario, COBRA's continuity may actually be cost-competitive for a short gap.
New employer plans are the simplest long-term solution, but timing is everything. Federal law under the ACA caps waiting periods at 90 days for employer plans with 50 or more full-time-equivalent employees. Many employers start coverage immediately or after 30 days. If your new plan starts within your 60-day SEP window and the gap in between is very short (under 2 weeks), going briefly uninsured may be a calculated risk. For any gap longer than 2 weeks, a Marketplace bridge or COBRA election protects against the statistical risk of an uninsured hospitalization. Spouse plans deserve special attention: a job switch is a qualifying event under most employer plans, giving your spouse 30 days to add you under Section 9831 of HIPAA. Spousal employer coverage is typically cheaper than any individual bridge option.
Medicaid Eligibility During a Job Transition in 2026
Medicaid eligibility during a job transition depends on your projected annual household income using Modified Adjusted Gross Income (MAGI) methodology. The 40 Medicaid expansion states plus DC use 138% FPL as their eligibility ceiling. For 2026, that means $22,025 for a single person and $45,540 for a family of 4 based on HHS ASPE 2026 poverty guidelines. Workers stepping from a high-salary role into unemployment or a significant pay cut may cross below that threshold for part of the year. Medicaid counts current monthly income annualized, not your prior-year income, so a genuine gap in earnings can create temporary Medicaid eligibility even for workers who previously earned well above the threshold. Apply through healthcare.gov or your state agency.
State Medicaid programs go by different names: California's Medi-Cal, Arizona's AHCCCS, Washington's Apple Health, Massachusetts's MassHealth, Wisconsin's BadgerCare, Oregon's OHP (Oregon Health Plan), Connecticut's HUSKY Health, and New Jersey's NJ FamilyCare. The 10 non-expansion states (Alabama, Florida, Georgia, Kansas, Mississippi, South Carolina, Tennessee, Texas, Wisconsin, Wyoming) have stricter income limits, typically below 100% FPL for non-disabled adults without children. Workers in non-expansion states who do not qualify for Medicaid and whose income is below 100% FPL fall into the coverage gap, where Marketplace subsidies also do not apply. For those workers, COBRA or going briefly uninsured are the only realistic bridge options unless the new employer plan starts within weeks.
Documents You Need for a Job-Switch SEP Application in 2026
Applying for a Special Enrollment Period through healthcare.gov after a job switch requires documentation that proves you lost qualifying employer coverage. The Marketplace may ask you to upload documents within 30 days of application. Submitting complete documentation upfront prevents delays and denial of SEP eligibility. The most common reason SEP applications are flagged for review is missing or mismatched proof-of-loss documentation: the date on your termination letter must align with the coverage end date you report.
- Proof of prior coverage loss: termination letter from your old employer on company letterhead showing your last day of employment and coverage end date, OR a COBRA election notice from your old employer
- HIPAA certificate of creditable coverage (your old insurer issues this automatically within 44 days of coverage loss; confirms prior coverage for Section 9831 SEP triggering)
- Social Security numbers for everyone applying (enrollee plus dependents)
- Current address and ZIP code (determines plan availability and network options)
- Projected 2026 household income estimate (use new-job salary prorated for remaining months plus any income from old job for months already worked)
- New employer offer letter or benefits start date confirmation (to document when new employer coverage begins, helping determine your bridge gap length)
- Birth certificates or adoption documents for any dependents being added
How the New Employer Waiting Period Interacts With Your 60-Day SEP
Federal law under the ACA (29 CFR 2590.715-2708) prohibits employer group health plans from imposing waiting periods longer than 90 days for otherwise eligible employees. Most large employers start coverage on the first of the month after 30 days of employment or immediately. The interaction with your 60-day SEP creates four scenarios. Scenario A: new coverage starts within 30 days of old coverage ending. No action needed; the gap is minor or nonexistent and likely not worth the administrative complexity of a bridge plan. Scenario B: new coverage starts 31 to 60 days after old coverage ends. A Marketplace SEP bridge plan makes sense; apply at healthcare.gov on day 1 of the gap. Scenario C: new coverage starts 61 to 90 days after old coverage ends. The 60-day SEP may expire before new coverage begins. Elect COBRA within 60 days as a backstop, or apply for a Marketplace plan immediately. Scenario D: new employer has no group health plan or you are a 1099 contractor. Treat this as a full job-to-self-employment transition; the Marketplace SEP is your primary option and COBRA may still apply from the old job.
Frequently Asked Questions
How long do I have to enroll in health insurance when switching jobs?
You have 60 days from the date your old employer coverage ends to enroll in an ACA Marketplace plan under the Loss-of-Coverage Special Enrollment Period. For your new employer's plan, the window is typically 30 days from your hire date (some plans allow 60 days). Medicaid has no deadline and is available year-round in expansion states. For COBRA, you have 60 days from your old coverage end date to elect continuation coverage. Missing the 60-day Marketplace SEP window generally means waiting until November 2026 Open Enrollment unless another qualifying life event occurs.
What documents do I need to prove I lost job coverage for the SEP?
Healthcare.gov requires proof that you lost qualifying employer coverage. The most accepted documents are a termination letter from your old employer on company letterhead showing your last day and coverage end date, a COBRA election notice, or a letter from your old insurer confirming coverage termination. The date on the document must match the coverage end date you report during enrollment. Your old insurer is required to issue a HIPAA certificate of creditable coverage within 44 days of your coverage loss, which also works as proof. Keep all these documents together before starting the SEP application.
Is COBRA worth it when switching jobs?
For most job switchers in 2026, COBRA is not the best financial choice. COBRA charges 102% of the full premium, meaning you pay your old employee contribution plus the employer's contribution plus a 2% admin fee. That typically runs $500 to $1,200 per month for individual coverage and $1,500 to $2,800 per month for family coverage in 2026. ACA Marketplace plans for a bridge period often cost $50 to $300 per month after premium tax credits for workers earning under 400% FPL ($63,840 single). The exception: if you have ongoing treatment with a specialist who is out of network on every available Marketplace plan in your area, COBRA's network continuity may justify the extra cost for a short period.
What if my new employer has a 90-day waiting period?
A 90-day waiting period means your new employer coverage begins 90 days after your hire date. Federal law caps waiting periods at 90 days under the ACA for applicable large employers. If your old coverage ends on the day you leave and your new coverage starts 90 days later, you need a bridge plan because your 60-day SEP expires before new coverage begins. Apply for a Marketplace SEP plan within the first 60 days. Alternatively, elect COBRA from your old employer within 60 days, which activates retroactively and provides continuous coverage until your new employer plan starts.
Can I temporarily enroll in Medicaid while between jobs?
Yes, if your income during the gap falls below 138% FPL in a Medicaid expansion state. For 2026, that is $22,025 for a single person or $45,540 for a family of 4. Medicaid uses current monthly income, not your prior annual income, so a genuine pay gap can create eligibility even if you earned above the threshold previously. Apply through healthcare.gov or your state Medicaid agency. Medicaid is free and has no enrollment deadline. Note: Medicaid is not available in the 10 non-expansion states for non-disabled adults without children.
What happens to my children's coverage when I switch jobs?
Your children may qualify for CHIP (Children's Health Insurance Program) at incomes up to 200 to 300 percent FPL depending on your state, even if your income disqualifies you from Medicaid. CHIP enrollment is year-round, and premiums are very low or free. Your job switch is also a qualifying event under your new employer's plan, and children can be enrolled within the 30-day new hire window. For children already on your old employer plan, CHIP is often cheaper than adding them to a Marketplace bridge plan or to COBRA.
Do I need a Form 1095-A if I use a Marketplace bridge plan during my job gap?
Yes. Healthcare.gov will mail you a Form 1095-A in January 2027 covering any months you were enrolled in a Marketplace plan during your 2026 job transition gap. You must use the 1095-A to complete IRS Form 8962 when you file your 2026 federal tax return. Form 8962 reconciles the advance premium tax credits you received (paid directly to the insurer) against your actual 2026 income. If your actual income was higher than estimated, you may owe back some subsidy as a tax liability. If lower, you receive a refundable credit.
What if I miss the 60-day SEP after my job switch?
Missing the 60-day SEP after losing job coverage means you generally cannot enroll in a Marketplace plan until the next ACA Open Enrollment Period, which runs November 1 through January 15 for 2027 coverage. Coverage under a plan picked during OEP starts January 1, 2027. Exceptions: if another qualifying life event occurs (marriage, birth, moving to a new state), that opens a new SEP. Medicaid is not subject to the 60-day rule and remains available year-round if you qualify by income. COBRA must also be elected within 60 days of the original coverage loss.
