Center on Budget and Policy Priorities: Trapped by the Firewall – Policy Changes Are Needed to Improve Health Coverage for Low-Income Workers
The Affordable Care Act (ACA) expanded health coverage to more than 20 million people, principally by improving access to Medicaid and the individual insurance market. While the law put in place new protections for people with employer-sponsored health insurance, it did not dramatically change that market, the major source of health coverage for people under age 65. Employer-sponsored coverage often works well, allowing many people to enroll in comprehensive health benefits using employer contributions that make premiums affordable. But the picture can be quite different for low-income workers./1
Frequently, low-income workers get less employer help with their premiums, are offered less robust coverage, and must pay a greater share of their income toward health care costs compared to higher-income workers. And even if an employer's offer of health coverage is not comprehensive or is unaffordable in practice, it may still disqualify low-income workers and their family members from getting a premium tax credit (PTC) for coverage in the marketplace. This is because the ACA included a "firewall" that makes people with employer-sponsored coverage offers ineligible for PTCs, provided that the employer coverage meets minimum federal standards for affordability and comprehensiveness./2 But the standards are insufficient, barring many low-income people from enrolling in subsidized marketplace coverage that would be far more affordable and comprehensive.
Low-income workers deserve renewed attention from policymakers to further expand health coverage and make it more affordable for those who have it. Roughly 2.7 million uninsured people have incomes under 400 percent of the poverty line (the income cut-off for PTCs) but can't claim the PTCs due to an offer of employer coverage./3 Millions more enroll in employer plans but struggle to pay premiums or find they have inadequate protection against high out-of-pocket costs. On average, workers with employer coverage with incomes below 200 percent of the poverty line spend 14 percent of income on premiums and out-of-pocket costs, compared to 7.9 percent for those between 200 and 400 percent of the poverty line, and 4.5 percent for those above 400 percent of the poverty line./4
Eliminating the ACA firewall would let low-income workers choose their best coverage offer, whether it's with their employer or at the marketplace with assistance from a PTC. That would reduce costs for workers and decrease the number of uninsured, but it would come at a high budgetary cost.
Short of eliminating the firewall, a range of policies could work around it to make coverage more affordable for workers by making more people eligible for PTCs and increasing awareness of the marketplace enrollment option:
Fix the "family glitch." Today an offer of affordable, adequate employee-only coverage disqualifies all family members from PTC eligibility, even when the family premium is very high as a share of income; this is referred to as the "family glitch." One fix would be to measure family affordability based on the cost of family coverage, rather than the cost of an employee-only plan.
Raise the standards for employer coverage offers. An employer coverage offer can be considered affordable and comprehensive under federal standards while still imposing high out-of-pocket expenses or covering a skimpy set of benefits. Raising these standards would improve employer coverage or, if the offer doesn't meet the improved minimum requirements, free more workers to enroll in subsidized marketplace plans.
Better equip PTC-eligible employees to enroll in marketplace coverage. Employers could do more to facilitate marketplace enrollment of employees who are ineligible for the workplace coverage. They could also be required to provide better upfront information about whether the employer offer is affordable and comprehensive or whether the worker can bypass the employer offer for subsidized coverage in the marketplace.
These options for making coverage more affordable for low-income workers could complement broader strategies for reducing health care costs and improving the quality of employer-sponsored insurance for all workers. Unfortunately, the
Low-Income People Face High Costs Even in "Affordable" Employer Coverage
The cost of employer-sponsored insurance has increased steadily in the last several decades and has consistently outpaced workers' earnings growth, even though premium growth has slowed notably since the ACA's passage. Between 2000 and 2010, family premiums increased by 114 percent, compared to a 36 percent increase in earnings; between 2010 and 2019, family premiums increased by 49 percent compared to a 23 percent increase in earnings./5
Employee premiums for employer-sponsored coverage are particularly burdensome for low-income workers. Employees pay, on average, 18 percent of the premium for single coverage and 30 percent for family coverage./6 Any given employee premium represents a higher share of income for low-income workers. For example, the average annual dollar amounts that covered workers contribute for family coverage is
High out-of-pocket costs also create hardships for low-income families./9 Total out-of-pocket health spending increased by 54 percent and deductibles by 176 percent from 2006 to 2016, according to the
All told, low-income workers pay a substantial share of their income toward health costs. Among workers who enroll in employer coverage, people with income below 200 percent of the poverty line spend, on average, 14 percent of their income on premiums and out-of-pocket costs./15 For comparison, people with income between 200 and 400 percent of poverty spend 7.9 percent of income, and people with income over 400 percent of the poverty line spend only 4.5 percent. (See Figure 1.)
Low insurance offer and take-up rates contribute to striking disparities in employer-sponsored coverage enrollment by income and race. In the lowest quartile of the wage distribution, only about one-third of private sector workers are offered coverage, with 22 percent of them actually participating. This compares to 92 percent of workers in the top wage quartile being offered coverage and 80 percent participating./16 (See Figure 2.)
See chart here (https://www.cbpp.org/research/health/trapped-by-the-firewall-policy-changes-are-needed-to-improve-health-coverage-for-low).
Employer-sponsored coverage is less common among Black and Hispanic people. About 60 percent of non-Hispanic white people have coverage through the workplace compared to 46 percent of Black people and 41 percent of Hispanic people./17 These groups are less likely to have workplace coverage mainly because they are disproportionately likely to be in lower-income households where employer coverage is less available, but these disparities exist at nearly every income level. (See Figure 3.)
Inadequate Employer Offers Can Make Workers Worse Off
The ACA's premium tax credits defray premium costs for low- and moderate-income families purchasing coverage in the marketplace, and cost-sharing reductions decrease out-of-pocket spending for people with income below 250 percent of the poverty line. Having an offer of employer-sponsored coverage makes someone ineligible for these subsidies, unless the offer is considered unaffordable or fails to meet a minimum value test. An offer is unaffordable if the lowest-cost plan covering only the employee costs more than about 10 percent of income (9.86 percent in 2019). A plan falls short of minimum value if its "actuarial value" is below 60 percent, meaning that it pays, on average, less than 60 percent of the cost of allowed benefits. If the employer offer is deemed affordable and meets minimum value, the employee is "firewalled" -- that is, blocked from receiving marketplace subsidies.
Because of the firewall, having an offer of employer coverage can make a lower-income worker worse off compared to a worker with no offer of coverage at all. A major issue is that the affordability standard is set at a level that requires low-income workers to pay a far greater share of income for an employer plan than people with the same income are expected to pay toward marketplace coverage. A single person making
In addition, minimum value is a relatively meager standard. Large employers (with 50 or more full-time workers) aren't required to cover the package of essential health benefits that plans in the individual or small group markets must cover. Instead, employer plans can meet minimum value if they cover preventive services, physician visits, and hospital inpatient services and meet the 60 percent actuarial value standard. But this can leave some workers, particularly lower-wage ones, with skimpy benefit plans that may not cover needed care. Notably, 60 percent is far lower than the actuarial value of coverage that low-income marketplace enrollees can generally purchase in the marketplaces and translates to sizeable out-of-pocket costs, such as deductibles in excess of
These factors create disparities between families with and without employer coverage offers and show why some employees may be better off if they are free to shift to the marketplace. For example:
A single person with income of
In the marketplace, a cost-sharing reduction would raise this consumer's benchmark plan's actuarial value to 94 percent. Deductibles for such plans average
For a family of three with income of
They'd also be guaranteed a plan with an 87 percent actuarial value in the marketplace, in line with a typical employer plan but much more generous than the 60 percent minimum value requirement.

Eliminating Firewall Would Reduce Disparities But Is Costly
Eliminating the firewall that prevents most people with employer-sponsored coverage offers from PTC eligibility would make an estimated 2.7 million more people 9 percent of the total uninsured population eligible for affordable coverage./23 Under this policy, employees would have a choice to enroll in their employer coverage or go to the marketplace. Many employees would likely choose to remain in employer-sponsored coverage, particularly middle- and higher-income workers whose income is too high for the PTC but who benefit substantially from the tax exclusion for employer-sponsored health insurance premiums. Workers who have less generous coverage offers or who are eligible for substantial PTCs would enter the marketplace.
Several groups the
The downside is cost. Many low- and moderate-income workers, particularly those with families, would move to the marketplace, generating increased federal costs for PTCs and cost-sharing assistance that would substantially exceed the federal savings from the tax exclusion for employer-sponsored coverage. Employers could also take certain measures that could further increase federal costs. First, some employers may encourage sicker or older workers to move to the marketplace, perhaps through design decisions that make their plans less attractive to people with serious health needs or through less subtle steering. Strong non-discrimination provisions would be necessary to prevent this. Second, employers would presumably be motivated to restructure their plans to maximize the benefits of both PTCs and the tax exclusion. That is, they'd probably have less incentive to keep premiums low for low-income workers (as long as they could avoid the penalty) since those workers could just go to the marketplace. Beyond further increasing federal costs, that could also mean that some middle-income people would see higher employee premiums (although employers could increase wages to compensate and employee dissatisfaction could mitigate premium increases).
Other Ways to Improve Coverage for Workers
Short of eliminating the firewall, a range of policies could work around it to make coverage more affordable for workers by making more people eligible for the PTC. To the extent a policy change increases PTC eligibility, there would be some degree of crowd-out: a substitution of one type of coverage for another, instead of uninsured people becoming newly covered. But that is balanced by the desirability of giving more affordable coverage to currently insured workers, particularly low-income workers. In addition, one potential benefit of enrolling more people in marketplace coverage is a modest premium reduction in the marketplace, as a result of more healthier people who previously didn't enroll in employer coverage due to cost joining the risk pool.
Fix the Family Glitch
More than 6 million people live in families that are ineligible for PTCs because they have an employer offer of single coverage that meets the federal affordability standard, even though the cost of family coverage from the employer exceeds the premium threshold, according to the
One potential fix would allow family members with unaffordable coverage offers to be eligible for PTCs, while the employees themselves remain subject to the firewall. An estimated 3 million people would become eligible for tax credits under this proposal, according to the
A second analysis concurred that fixing the family glitch would reduce families' average total health care spending by thousands of dollars and drop their risk of spending at least 20 percent of income on health care by more than two-thirds./29
Raise the Standards for Employer Coverage Offers
As explained above, employer-sponsored coverage is considered unaffordable if the employee's share of the premium for the lowest-cost plan exceeds roughly 10 percent of household income (9.86 percent in 2019). Reducing this threshold could prod more employers to improve coverage affordability or release more workers to seek subsidized marketplace plans if their employers did not meet the new standard. This could increase penalty collections, helping to finance the shift of workers to marketplace coverage with PTCs. Alternatively,
Lowering the affordability threshold would primarily benefit low-income workers, who are more likely to have high premiums relative to income and would be eligible for the most substantial assistance if no longer firewalled. It would also complement congressional proposals to make PTCs more generous for marketplace consumers. For example, legislation by Representatives
But even if the affordability threshold were reduced to 8.5 percent, a low-income person with an employer plan could pay considerably more for less coverage than someone with the same income who is eligible for a marketplace subsidy. For example, a person with income at 150 percent of the poverty line (
Another way to improve health care affordability for people with offers of job-based coverage would be to increase the share of anticipated health costs that the plan pays for. As explained above, a large-employer or self-insured group plan currently meets the minimum value standard if it covers at least 60 percent of the plan's total allowed benefit cost, according to an online calculator that the
One option would be to raise the minimum value standard from 60 percent to 70 percent to align with the marketplace benchmark. Raising the minimum value standard wouldn't affect most employers since the average employer plan has an actuarial value of 85 percent./31 While it could lead some employers to pass on premium increases to employees, the increase in the employee premium would be constrained by the affordability standard. Other employers offering low-value plans may drop coverage altogether but, to the extent that employees are eligible for PTCs, this might give more workers and their families access to more affordable and comprehensive coverage in the marketplace.
Another approach would be to define a more robust benefit standard. As noted, the benefit standard set for purposes of minimum value is less than what's required in the individual or small group markets. When the ACA passed, the assumption was that employer-sponsored coverage at large firms was already sufficiently comprehensive. But as the employer coverage requirement was implemented, it became clear that a small minority of employers were not providing comprehensive coverage. That led the
Improvements to the benefit requirements would help vulnerable workers who are offered the barest coverage today. For example, to qualify as minimum value coverage, large and self-insured employers' health plans could be required to meet their state's essential health benefit standard ten defined categories of items and services as individual and small-group coverage must do. An approach to avoid the complexity of employers having to meet a different standard in every state in which they operate is to either create a nationwide benefit standard based on the essential health benefit standard or allow employers to choose to follow one state's standard, as they do to determine to which services the ACA's annual and lifetime limits apply. The vast majority of large and self-insured plans exceed these minimum standards, but for employers with plans that don't, their workers would no longer be firewalled into subpar coverage.
Help Eligible Workers Access Marketplace Subsidies
Some workers and their families aren't firewalled but don't realize it. One group often in this situation is workers who aren't eligible for their employer's coverage. Employers could be required to do more to connect those workers to the marketplace, and HHS could lower barriers to marketplace enrollment. Another group is workers who are eligible for employer-sponsored coverage but whose coverage is inadequate (i.e., doesn't meet existing affordability or minimum value standards). Employees need help to determine whether their employer offer disqualifies them from marketplace subsidies or whether the offer falls short and leaves them eligible for more affordable, comprehensive coverage in the marketplace. Reaching out to these groups of PTC-eligible workers may reduce the number of uninsured.
One policy change that might help is to change the structure of the employer responsibility requirement. The current structure where an employee claiming the PTC potentially triggers a penalty for the employer discourages employers from connecting people to the marketplace. (See box, "'Shared Responsibility' Requirement Could Be Improved.") Other approaches are discussed below.
Reaching Workers Ineligible for Employer-Sponsored Coverage
Even if an employer offers coverage, workers can still be ineligible for a variety of reasons. Large employers are only required to offer coverage of 95 percent of full-time workers, for example, and can exclude part-time employees or employees in certain locations or job classifications./33 Employers may also establish waiting periods for enrollment in their coverage or use a "measurement period" to delay eligibility for up to a year for new workers who they contend don't meet full-time status. Other people are eligible for coverage then lose eligibility. Job loss is the most common reason people lose employer coverage, but other workers can become ineligible despite still being employed, such as when their hours are reduced or their position or job location changes.
Employers are well-positioned to identify employees who have not been offered coverage, whose coverage has changed, or who are losing their coverage, and to help them find other sources of insurance. Regardless of an employee's eligibility for employer-sponsored coverage, federal law requires employers to inform new employees about the marketplace and the PTC./34 The law could be expanded to direct the
Employers are required to notify people who are losing their employer health benefits that they are eligible to continue with that coverage (typically by paying the full premium) under what's known as "COBRA," after the federal law that created it./35 The DOL model notice for COBRA, which many employers use, contains language about the availability of the marketplace, but the information could be expanded to include: marketplace website and contact information, the availability of enrollment assistance, the availability of financial assistance, examples of how that financial assistance lowers premiums for a family, and the availability of a special enrollment period allowing people losing employer coverage to enroll outside the normal annual open enrollment period. Beyond adding information to the model notice, DOL could require this information in every COBRA notice.
COBRA notices are likely to reach a large portion of the 10 million uninsured people eligible for a special enrollment period due to job loss every year./36 Providing workers with more information about financial assistance in the marketplace could help people avoid gaps in coverage during employment transitions or unnecessarily paying for COBRA coverage. Connecting people with in-person enrollment assistance could also help people bridge the gap when they lose job-based coverage.
Reaching Workers Who Are Offered Employer-Sponsored Coverage But Not Firewalled
Another group of workers who may be able to seek subsidized marketplace coverage are those who are eligible for employer-sponsored coverage that is unaffordable or fails to meet minimum value, but it's often difficult for workers to determine on their own whether their employer's health benefits meet those standards. To remedy this, employers could be required to tell an employee in advance if their coverage offer meets minimum value and how to calculate whether the premium for that plan is affordable. The information would need to be specific to the employee and account for the litany of exceptions and complications that employees are expected to navigate for themselves today.
Without requiring employers to provide such information, coverage offers can be hard for employees to parse. To start, an employee must know whether any plan is "eligible employer-sponsored coverage" -- meaning it meets the ACA's rules as a plan offer -- versus a non-qualifying supplemental coverage option, such as fixed indemnity coverage, that offers scant benefits at a lower cost. Employers should have to be transparent about which plans qualify as eligible plans.
Once the employee knows which plan is an eligible employer-sponsored plan, determining whether it meets the minimum value and affordability requirements is similarly complicated. An employee would need to know the minimum value and calculate the affordability of each plan to know if any one plan meets both requirements to disqualify an employee from a PTC. Only then would an employee have the information to make an informed determination about whether the employer's offer precludes PTC eligibility for themselves and their family.
Minimum value can't be determined independently by employees; rather, it's disclosed on an employer-provided summary of benefits and coverage (SBC). Employers are required to make the forms available to workers for each plan they offer, but in practice, many employees don't know they are entitled to this form or have trouble getting it. Even if they have it, the form is lengthy and the minimum value designation is easily missed. The form also doesn't spell out the consequences of having an offer that is not minimum value; for example, an employee whose plan's minimum value is 58 percent isn't told how to use that information.
The affordability standard requires that a plan cost less than 9.86 percent of income (in 2019), but special rules can make the calculation more than a function of just premium cost. Special tax provisions like for wellness plans, health reimbursement arrangements (HRAs), or cafeteria plans also affect whether a plan is considered affordable but are not transparent to even an employee who's very knowledgeable about their benefits.
For example, one staffing company offers three medical plans: "Enhanced MEC," "Fixed Indemnity," and "Major Medical."/37 The Enhanced MEC plan doesn't cover hospitalization so doesn't appear to meet the
No single required document available to employees at open enrollment captures all these variables, making it hard for employees to know whether they are firewalled or eligible for a marketplace subsidy. A form called the Employer Coverage Tool solicits key information including whether the offer has a waiting period, extends to family members, or meets minimum value, and the employee's share of the premium but completing the form is optional for employers./38 And, crucially, the form doesn't tell employees how to use premium information to make an affordability determination. Because these forms aren't required, they are often completed in one-off, and sometimes haphazard, ways. For example, two employees with identical positions going to the same human resources office may get different responses on the Employer Coverage Tool.
Requiring employers to provide reliable, comprehensive information about their health coverage offers in advance of the coverage year would make it possible for workers to determine whether they have an offer that bars them and their families from PTCs. This would help more employees gain access to subsidized coverage in the marketplace if they are eligible for it, while also preventing people from incorrectly claiming federal subsidies and later having to repay a credit they were not eligible to receive. Congressional proposals aimed at simplifying federal reporting requirements for employers include prospective reporting systems. But those proposals would only require general information to be shared with the employee information that is insufficient to accurately determine PTC eligibility for an individual employee./39 Future proposals should instead seek to collect information from employers that is reliable and specific so that the employee can use it to understand whether they are eligible for marketplace subsidies instead. The Employer Coverage Tool could be a useful starting point, if employers were required to complete it and provide it to workers.
Administration Actions Threaten to Raise Costs, Reduce Benefits for Workers

Requiring verification of job loss to enroll in marketplace coverage. A person can enroll in marketplace coverage outside the annual open enrollment period if they lose qualifying coverage, often because of job loss or a reduction in work hours. The Administration made it more difficult to access this special enrollment period by requiring pre-enrollment verification. Documentation can be difficult for people to produce in a timely way given other urgent concerns people have when they leave a job or experience a significant reduction in income.
Approving new association health plans (AHPs). The Administration opened a new gateway for employers to form private associations to provide health insurance that is exempt from some consumer protections found in the small group market. For example, AHPs could effectively discriminate based on health conditions by excluding certain essential health benefits required under other plans, like coverage of mental health treatment and prescription medications for costly conditions, since people who need those benefits would not sign up. In addition, an AHP could structure its membership rules and marketing tactics in ways more likely to attract healthier people and groups, while charging far more to others, such as small groups that are made up of women or older people, that work in professions deemed high risk, or that live in areas classified as higher cost.
