Marketplace vs. Employer Plan: When the Marketplace Is Actually Cheaper

The affordability test: 9.96% of income

The ACA says you can only get marketplace subsidies if your employer's plan is either unaffordable or doesn't meet minimum value requirements. The IRS indexes the affordability threshold each year. For 2026, it is 9.96% of household income for self-only coverage (up from 9.02% in 2025). That increase means more employer plans are now considered "affordable" under the test, which makes it harder to qualify for marketplace subsidies.

If the employee-only premium your employer charges exceeds 9.96% of your household income, the plan is considered unaffordable, and you can shop the marketplace with full subsidy eligibility.

For example: if your household income is $50,000 and your employer charges you $420/month ($5,040/year) for self-only coverage, that's 10.1% of your income. That exceeds the 9.96% threshold, so you qualify for marketplace subsidies.

But if your employer charges $400/month ($4,800/year), that's 9.6% of income, which is under the threshold. In that case, you're generally locked out of marketplace subsidies even if the plan isn't great.

The family glitch (and the fix)

For years, there was a painful loophole in how affordability was calculated. The IRS only looked at the cost of employee-only coverage when deciding if a plan was affordable. If self-only coverage cost $200/month but adding your spouse and kids pushed it to $1,200/month, the plan was still considered "affordable" based on that $200 figure. Your family couldn't get marketplace subsidies even though covering them through the employer plan would eat up a quarter of your paycheck.

That changed in 2023. The IRS issued a rule that now measures affordability separately for the employee and for family members. If the cost of family coverage through your employer exceeds the affordability threshold as a percentage of household income, your spouse and dependents can qualify for marketplace subsidies on their own, even if the employee's self-only coverage is considered affordable.

This matters a lot. A family of four might save several hundred dollars a month by keeping the employee on the employer plan while putting the spouse and kids on a subsidized marketplace plan.

When marketplace subsidies beat employer coverage

There are several common situations where the marketplace comes out ahead:

• Your employer charges a lot for family coverage. On average, employers pay about 84% of individual premiums but only about 73% of family premiums. The employee share for family coverage averages around $6,850 per year. If your employer is less generous than average, or if your income qualifies you for substantial marketplace subsidies, the marketplace may be cheaper for covering dependents.
• Your household income is moderate. Marketplace subsidies are based on income relative to the federal poverty level. A family of four earning $60,000 could receive a significant monthly tax credit. If that credit exceeds what the employer contributes, the marketplace wins on price.
• You qualify for cost-sharing reductions. If your income is below 250% FPL and you pick a Silver marketplace plan, you get reduced deductibles, copays, and out-of-pocket maximums. Employer plans don't offer this. A CSR Silver plan can have an effective actuarial value of 87% or even 94%, which is better than most employer Gold plans.
• Your employer's plan has a high deductible. Some employers offer plans that technically meet the minimum value test (60% actuarial value) but have deductibles of $5,000 or more. A subsidized marketplace Silver plan might have a lower deductible and lower out-of-pocket costs.

The "affordable but bad" employer plan problem

This is the frustrating middle ground. Your employer's plan passes the affordability test (employee premium is under the threshold), so you can't get marketplace subsidies. But the plan itself has a $7,000 deductible, limited provider networks, and high coinsurance.

In this case, your options are limited. You can take the employer plan and absorb the high out-of-pocket costs. You can buy a marketplace plan, but you'll pay full price without subsidies. Or you can see if your employer offers multiple plan options at different price points.

If your employer offers an HSA-eligible plan, one strategy is to pair that high-deductible plan with a Health Savings Account. You and your employer can both contribute pre-tax dollars, which helps offset the deductible. But this only works if you can afford to set money aside.

How to compare total costs

Premiums alone don't tell the story. To compare an employer plan against a marketplace plan, you need to look at the full picture:

1. Monthly premium. For the employer plan, this is what's deducted from your paycheck (pre-tax). For the marketplace, it's the plan premium minus your tax credit.
2. Deductible. How much you pay out of pocket before insurance covers anything. Employer plans range widely. Marketplace plans with CSR can be very low.
3. Copays and coinsurance. What you pay per visit or per service after the deductible. Compare the common services you actually use: primary care, specialists, prescriptions, labs.
4. Out-of-pocket maximum. Your worst-case annual spending. The 2026 ACA limit is $9,200 for an individual. Employer plans may set it higher or lower.
5. Provider network. Will your doctors accept the marketplace plan? Employer plans often have broader networks, but not always.
6. Tax treatment. Employer premiums are pre-tax, which effectively gives you a discount equal to your marginal tax rate. Marketplace premiums are paid with after-tax dollars (the tax credit is applied separately). Factor this in.

A simple approach: estimate your expected annual spending under each option. Multiply the monthly premium by 12, add in realistic estimates for deductible and copay spending based on how much care you typically use, and compare the totals.

Can you have both?

You can enroll in an employer plan and a marketplace plan at the same time. There is no law against it. But you generally cannot receive marketplace subsidies if you have access to affordable employer coverage that meets minimum value. So while you could technically buy both, you'd be paying full price for the marketplace plan, which rarely makes financial sense.

The exception is the family glitch fix scenario: the employee stays on the employer plan, while family members who don't have access to affordable family coverage go on the marketplace with subsidies. This split approach is increasingly common and can be the cheapest option for households with moderate incomes.

When to stick with employer coverage

Employer plans are usually the better deal when:

• Your employer pays a large share of the premium (80%+ for family coverage).
• Your income is too high for meaningful marketplace subsidies (roughly above 400% FPL in 2026 with the return of the subsidy cliff).
• Your employer offers good plan options with reasonable deductibles and a strong provider network.
• Your employer contributes to an HSA or HRA that adds real value.
• You want the simplicity of payroll deductions and the tax advantage of pre-tax premiums.

For many people, employer coverage is still the best option. But it is not automatically the best option. If your situation involves high family premiums, moderate income, or thin employer benefits, run the numbers both ways before assuming your employer's plan is the right call.
