You can enroll in Covered California even if your employer offers insurance. Nothing in state or federal law forces you to take the job-based plan. What changes when your employer offers coverage is your access to Premium Tax Credits: if that plan is considered affordable and meets a minimum value standard, you’ll pay full price on the marketplace. If it fails either test, you can buy a subsidized plan through Covered California instead.
The 9.96% Affordability Test
The federal government decides whether your employer’s plan is “affordable” using a single percentage. For the 2026 plan year, the plan is affordable if your share of the premium for the cheapest self-only option that meets minimum value is 9.96% or less of your household income.1IRS.gov. Rev Proc 2025-25 Only the employee-only cost counts here, not what you’d pay to add a spouse or kids.
The math is quick. Multiply your total household income by 0.0996. If the annual cost of the cheapest self-only plan your employer offers is higher than that number, the plan fails and you can shop Covered California with subsidies.2Office of the Law Revision Counsel. 26 USC 36B – Refundable Credit for Coverage Under a Qualified Health Plan If it’s lower, the plan is affordable and Premium Tax Credits are off the table, though you can still buy a marketplace plan at full price.
The Minimum Value Standard
Affordability is one gate. Minimum value is the other. An employer plan meets minimum value when it’s designed to cover at least 60% of expected costs for covered benefits and provides substantial coverage for physician and hospital services.3Internal Revenue Service. Minimum Value and Affordability Most traditional group plans clear this easily. Some limited-benefit or skinny plans don’t.
If the plan fails minimum value, you’re treated as though no employer offer exists, and you can receive the full subsidy your income qualifies you for.3Internal Revenue Service. Minimum Value and Affordability Your HR department can tell you whether the plan meets the standard; the answer also appears on the Employer-Sponsored Coverage Worksheet you’ll use when applying.
When Family Members Qualify Separately
The affordability test used to look only at the employee’s self-only premium, even when adding a spouse and children pushed the total cost far past what a household could carry. Regulatory changes fixed this starting in 2023. Family members are now judged on the cost of family coverage. If covering the whole family through your employer costs more than 9.96% of household income for 2026, your spouse and children can get Premium Tax Credits through Covered California even if you individually cannot.2Office of the Law Revision Counsel. 26 USC 36B – Refundable Credit for Coverage Under a Qualified Health Plan This matters most when the employer heavily subsidizes the employee tier but charges a lot more for dependents.
Income Limits Still Apply
Even if your employer plan fails the affordability test, you still need household income in the eligible range for Premium Tax Credits. The baseline ACA rule sets that range at 100% to 400% of the federal poverty level.4Internal Revenue Service. 5HHS ASPE. 2026 Poverty Guidelines
Between 2021 and 2025, Congress lifted the 400% cap so higher earners could receive partial help. That expansion expired at the end of 2025, and early in 2026 the House passed a three-year extension. Whether it becomes law affects anyone above 400% FPL, so check the current status before assuming you’re out.
California also runs its own state premium assistance on top of federal credits. Households between 100% and 165% of FPL qualify for extra state subsidies that can bring premiums to zero or near-zero for the 2026 plan year.6Covered California. 2026 California State Premium Subsidy Program
What to Get From Your Employer Before You Apply
Covered California uses an Employer-Sponsored Coverage Worksheet to collect the information the system needs to run the affordability calculation.7Covered California. Employer-Sponsored Coverage Worksheet Three numbers matter:
- The monthly premium you’d pay for the cheapest self-only plan that meets minimum value.
- The monthly cost of family coverage, if you’re checking eligibility for dependents.
- Your projected household income for the coverage year, including wages, tips, investment income, and other taxable sources.
HR can usually pull these figures on request. Once you have them, enter the numbers on the Covered California application and the site handles the affordability math for you.
When You Can Actually Switch
Open enrollment for 2026 coverage runs from November 1 through January 31, 2026.8Covered California. Covered California Open Enrollment 2026 Inside that window, anyone can enroll or switch plans for any reason.
Outside open enrollment, you need a qualifying life event. Losing your employer-sponsored coverage is one of the most common. You can report the loss up to 60 days before or after it happens and still qualify for a Special Enrollment Period.9CMS. Understanding Special Enrollment Periods Marriage, a new baby, a move, and loss of Medi-Cal also count.10Covered California. Major Life Changes
Here’s the trap. Voluntarily dropping your employer’s plan while everything else stays the same does not create a Special Enrollment Period. If you want to move to Covered California without a qualifying event, you wait for open enrollment.
COBRA Doesn’t Lock You In, But the Clock Does
When you lose your job, you’ll likely be offered COBRA. You don’t have to take it. Losing job-based coverage triggers a 60-day SEP on Covered California, and marketplace coverage with subsidies almost always beats unsubsidized COBRA on price.
If you do elect COBRA, you can still use the loss-of-coverage SEP to switch to a marketplace plan, but only if you’re within 60 days of when your employer-sponsored plan actually ended.11CMS. COBRA Coverage and the Marketplace After that, dropping COBRA on your own doesn’t open a new window. You wait for open enrollment or for COBRA itself to run out. Compare prices immediately when you lose your job, not weeks later.
Going Without Coverage Isn’t a Free Option
California requires residents to maintain minimum essential coverage or pay the Individual Shared Responsibility Penalty at state tax time.12California Legislative Information. California Code GOV 100705 For 2025, the penalty is at least $950 per uninsured adult and $475 per uninsured child, or 2.5% of household income above the filing threshold, whichever is higher.13FTB.ca.gov. Health Care Mandate – Personal These figures are indexed and typically rise each year. If you turn down your employer’s plan, don’t leave a gap before Covered California coverage begins.
Reconcile at Tax Time
If you take advance Premium Tax Credits through Covered California, you reconcile them on your federal return using Form 8962.14Internal Revenue Service. Premium Tax Credit – Claiming the Credit and Reconciling Advance Credit Payments Covered California sends Form 1095-A early in the year with the numbers you’ll need. Skipping this step delays any refund you’re owed.
Your subsidy is based on the income you projected when you applied. Earn more than you estimated and your actual credit shrinks, so you’ll owe the difference. Earn less and you get more credit back. For the 2026 tax year, there is no cap on repayment of excess advance credits.15IRS. Updates to Questions and Answers About the Premium Tax Credit That’s a real change from earlier years, when repayment was capped by income. Report income changes to Covered California as they happen so your monthly subsidy adjusts in real time. Getting your estimate close to actual is the single best way to avoid a tax-time surprise.
