Individual Coverage Health Reimbursement Arrangements (ICHRAs) have been marketed as a win-win solution for employers and employees alike.
Employers get predictable healthcare costs and reduced administrative burden, while employees gain the freedom to choose their own health insurance plans.
On paper, it’s an elegant solution to the escalating complexity and expense of traditional group health coverage.
But there’s a catch—or rather, several catches—that many employees don’t discover until tax season rolls around. What seemed like a straightforward benefit arrangement can transform into an unexpected tax liability, particularly when state tax laws and federal premium tax credit interactions come into play.
These hidden costs can range from mildly annoying to financially devastating, depending on an employee’s circumstances and location.
The Federal Framework Seems Simple Enough
At the federal level, ICHRA reimbursements are designed to be tax-free for employees. When an employer contributes to an ICHRA and employees use those funds to pay for qualified medical expenses—including individual health insurance premiums—that money isn’t considered taxable income.
It’s treated similarly to employer contributions to a traditional group health plan, which is one of the most significant tax advantages in the American benefits system.
This federal tax treatment is genuinely beneficial and represents real value for employees. The problem is that the federal framework is only part of the equation, and for many workers, the complications arise from sources they never anticipated.
If you’re considering an ICHRA as an employee or evaluating whether to offer one as an employer, it’s crucial to learn more about how these arrangements interact with both state tax systems and federal subsidy programs before making any commitments.
The State Tax Complication
Here’s where things get messy: not all states conform to federal tax treatment of ICHRAs. While the IRS says ICHRA reimbursements aren’t taxable income, some states haven’t updated their tax codes to match this treatment.
The result? Employees can find themselves owing state income tax on ICHRA reimbursements that they thought were tax-free.
California, for instance, has historically been slow to conform to certain federal health benefit provisions. New Jersey has similar non-conformity issues with various federal tax treatments.
The specific details vary by state and can change from year to year as state legislatures update their tax codes—or don’t.
What makes this particularly insidious is that most employees aren’t tax experts and have no reason to assume that their state would tax something the federal government doesn’t.
They accept the ICHRA, receive their reimbursements throughout the year, and then get blindsided when they prepare their state tax return and discover they owe hundreds or even thousands of dollars more than expected.
The practical impact depends on the state’s income tax rate and the size of the ICHRA contribution. Consider an employee receiving $6,000 annually in ICHRA reimbursements in a state with a 5% income tax that doesn’t conform to federal treatment.
That’s an unexpected $300 tax bill. In a higher-tax state like California, with rates that can exceed 9% for middle-income earners, the same $6,000 could trigger a $540+ surprise bill.
The Premium Tax Credit Cliff
The other major hidden cost involves the interaction between ICHRAs and premium tax credits (PTCs) available through the Affordable Care Act marketplace. This is where the math gets truly complicated and where employees can face the most significant financial surprises.
Premium tax credits are available to individuals who purchase marketplace coverage and meet certain income requirements. The credits are substantial—often thousands of dollars per year—and are designed to make individual health insurance affordable for middle-income families.
Many employees who might be eligible for these credits in a normal marketplace purchase scenario discover that their ICHRA offer disqualifies them from receiving any subsidy.
Here’s how it works: if an employer offers an ICHRA that’s considered “affordable” under ACA rules (meaning the employee’s required contribution for the lowest-cost silver plan, after the ICHRA allowance, doesn’t exceed 9.02% of their household income for 2025), then the employee and their family members cannot claim premium tax credits. The ICHRA offer makes them ineligible, period.
The problem arises when employees don’t fully understand this dynamic or when the employer’s ICHRA contribution is just barely enough to be “affordable” under the technical definition but isn’t actually sufficient to purchase quality coverage.
An employee might have previously been receiving $5,000 or more in premium tax credits to help pay for a marketplace plan. Now, with the ICHRA offer, those credits evaporate—even if the ICHRA contribution doesn’t fully replace what they were getting in subsidies.
Let’s walk through a realistic scenario. A family of four with a household income of $75,000 might qualify for approximately $8,000 in annual premium tax credits without an ICHRA. Their employer then offers an ICHRA with a $7,000 annual contribution.
Under the affordability calculation, this ICHRA offer is deemed affordable, making the family ineligible for premium tax credits.
But if the actual cost of coverage for this family is $15,000 per year, they’re now paying $8,000 out of pocket (the gap between the ICHRA contribution and the total premium) versus the roughly $7,000 they would have paid with premium tax credits. They’re actually worse off financially, even though they’re receiving an employer benefit.
The Coverage Gap Nightmare
There’s also a timing issue that creates what some benefits experts call “coverage gap bombs.” Because ICHRAs must coordinate with individual insurance policies rather than group plans, there can be gaps in coverage during transitions—when an employee starts a new job, when the calendar year turns over, or when they leave employment.
During these gaps, employees might go without coverage or might have to pay full price out of pocket temporarily.
If they’ve been estimating their tax liability based on having consistent ICHRA reimbursement throughout the year, these gaps can throw off their calculations.
Worse, if they lose ICHRA eligibility partway through the year (due to job loss or status change), they might become eligible for premium tax credits again—but reconciling all of this on their tax return becomes an accounting nightmare.
The IRS requires detailed reporting and substantiation for ICHRA arrangements. Employees need to track exactly what was reimbursed, when, and for what purposes.
If there’s any mismatch between what was reported by the employer and what the employee claims, or if reimbursements were used for non-qualified expenses, the employee could face additional tax liability plus penalties.
The Information Asymmetry Problem
Perhaps the most frustrating aspect of these hidden costs is that they stem largely from information asymmetry.
Employers implementing ICHRAs often don’t fully understand the state tax implications or premium tax credit interactions themselves, so they can’t adequately warn employees. Benefits consultants who sell and implement these arrangements may not emphasize the downsides, particularly the complex tax scenarios.
Employees, for their part, are making decisions about their health coverage based on incomplete information.
They hear about the employer contribution amount and assume it’s pure upside, not realizing they might be trading valuable premium tax credits for a nominally similar but actually inferior arrangement. They don’t think to investigate their state’s tax conformity status because why would they?
What Employees Need to Know?
If you’re an employee being offered an ICHRA, there are specific questions you need to ask before opting in. First, does your state conform to federal tax treatment of ICHRAs, or will you owe state income tax on the reimbursements?
Your employer’s HR department should be able to answer this, though you may need to verify with a tax professional.
Second, if you currently receive or would potentially qualify for premium tax credits, calculate whether the ICHRA contribution truly replaces what you’d lose in subsidies.
Don’t just compare the dollar amounts—actually price out marketplace plans both with and without considering the ICHRA to see which scenario leaves you better off.
Third, understand the administrative requirements. What documentation do you need to provide for reimbursement? How quickly are claims processed? What happens if you have a coverage gap? These seemingly minor details can create real financial stress if not handled properly.
The Employer Responsibility
For employers, the message is clear: transparency is essential. If you’re offering an ICHRA, you have an ethical obligation to help employees understand not just the benefits but also the potential drawbacks and complications.
This might mean providing access to benefits counselors, creating detailed comparison tools, or even hiring third-party advisors who can help employees navigate the decision.
You should also be proactive about the state tax issue. If your state doesn’t conform to federal ICHRA treatment, warn employees explicitly and help them plan for the tax impact. Consider whether your ICHRA contribution amounts need to be adjusted upward to compensate for state tax liability.
Looking Forward
ICHRAs aren’t inherently bad—they’re a tool that works well in certain situations for certain employers and employees.
But they’re far more complex than they first appear, and the hidden costs are real and significant for many workers.
As these arrangements become more common, we’re likely to see increasing complaints and potentially regulatory responses to address some of the more problematic aspects.
In the meantime, caveat emptor applies. Employees need to do their homework, ask tough questions, and potentially consult with tax professionals before accepting ICHRA coverage.
What appears to be a generous benefit might come with strings attached—strings that tighten considerably when April 15th rolls around.
