Millions of Americans rely on tax-advantaged Health Savings Accounts (HSAs) to cover rising medical costs, but a surprising number pick insurance plans that don’t qualify for HSA contributions at all. If you’ve ever wondered What Makes a Plan HSA Eligible, you’re not alone—this confusion costs thousands of people hundreds (or even thousands) of dollars in lost tax savings every year.
In this guide, we’ll walk through every non-negotiable requirement for an HSA-eligible plan, break down common plan types that qualify, explain common pitfalls to avoid, and even share tips to maximize your HSA benefits once you have the right coverage. Whether you’re a new HSA user or looking to switch plans for the next tax year, this breakdown will give you all the clear, actionable information you need.
The Foundational Rules of HSA-Eligible Plans
Before diving into plan specifics, it’s critical to know the non-negotiable baseline rules the IRS enforces for all HSA-qualified coverage. At its core, a plan is HSA-eligible only if it meets three key criteria: it is a qualifying high-deductible health plan, it does not offer disqualifying first-dollar coverage, and you are not enrolled in a plan that bars HSA contributions. Let’s break each of these down clearly: first, a qualifying HDHP has a minimum annual deductible and a maximum annual out-of-pocket limit set by the IRS each year. Second, the plan cannot cover non-preventive medical costs before you meet your deductible—preventive care like annual checkups, vaccinations, and cancer screenings can still be covered upfront without counting toward your deductible. Third, you cannot be enrolled in Medicare (with limited exceptions for certain Medicare Advantage plans) or another health plan that doesn’t qualify as an HDHP.
2024 IRS Deductible and Out-of-Pocket Maximums for HDHPs
Now that we’ve covered the foundational rules, let’s zoom in on the specific numerical limits that define a qualifying HDHP for the 2024 tax year. If you’ve ever shopped for HSA-eligible plans, you’ve probably seen references to “HDHP” everywhere—and for good reason: the high deductible is the single most defining feature of a qualifying plan. The IRS adjusts the minimum deductible and out-of-pocket maximum limits every year to account for inflation, so even if you picked a qualifying plan in 2023, you’ll need to double-check the 2024 numbers to keep your HSA eligibility intact. Many people accidentally enroll in a plan that used to qualify but no longer meets the updated IRS thresholds, which means they can’t contribute to their HSA for the year.
The 2024 IRS official limits for qualifying HDHPs are clear and straightforward, as laid out in the table below:
| Coverage Type | Minimum Annual Deductible | Maximum Annual Out-of-Pocket Limit |
|---|---|---|
| Individual | $1,600 | $8,050 |
| Family | $3,200 | $16,100 |
It’s important to note that these are only the minimum requirements—plans can have higher deductibles and out-of-pocket maximums and still qualify for HSA contributions. For example, a family plan with a $4,500 deductible and $20,000 out-of-pocket limit will still be HSA-eligible, as long as it meets or exceeds the 2024 minimums. Some employers even offer plans with lower out-of-pocket maximums than the IRS cap, which can be a great bonus for plan members.
One common point of confusion is that “high deductible” doesn’t mean the plan is useless for routine care. Most HSA-eligible HDHPs still cover preventive care at 100% before you meet your deductible, so you won’t have to pay out of pocket for annual physicals, flu shots, or colonoscopies. This preventive care coverage is one of the key ways HDHPs balance their higher upfront deductibles with valuable benefits for plan members.
What Plan Coverage Disqualifies You From HSA Contributions?
Next up, let’s talk about the types of plan coverage that can undo your HSA eligibility, even if you have a qualifying HDHP. Even if you have a qualifying HDHP, certain extra coverages can strip your plan of its HSA eligibility. The IRS prohibits plans that offer “first-dollar” coverage for non-preventive medical costs before you meet your deductible, as this undermines the high-deductible structure that HSAs are designed for. Let’s break down the most common disqualifying coverages.
The full list of disqualifying coverages includes:
- Coverage for prescription drugs (other than over-the-counter medications, which are now allowed without a prescription in 2023+) before meeting your deductible
- Coverage for doctor’s office visits, urgent care, or emergency care before you meet your deductible
- Spouse or dependent coverage that is not an HDHP
- Additional health insurance policies that pay for medical expenses before your HDHP deductible is met (like a supplemental insurance plan)
There are a few narrow exceptions to these rules, however. For example, you can have a separate dental or vision plan that covers care before your HDHP deductible, as long as that dental/vision coverage is not a substitute for medical care. Many employers offer standalone dental and vision plans alongside HSA-eligible HDHPs, which is a popular and allowed perk for employees.
Another key exception is that you can have a flexible spending account (FSA) for dependent care or adoption assistance, even if you have an HSA-eligible HDHP. These FSAs are not considered disqualifying medical coverage, so they won’t impact your HSA eligibility. This is a great way to save for both medical expenses and dependent care costs without losing your HSA benefits.
Who Is Allowed to Contribute to an HSA for an Eligible Plan?
Moving on from plan coverage rules, let’s shift focus to personal eligibility: even if you have a qualifying HDHP, you might not be allowed to contribute to an HSA. Having an HSA-eligible plan doesn’t automatically mean you can contribute to an HSA—your personal eligibility also matters. The IRS has strict rules about who can open and fund an HSA, even if you have the right insurance plan. Let’s walk through who qualifies to make HSA contributions.
To legally contribute to an HSA, you must meet all of the following criteria:
- You are enrolled in a qualifying HDHP, as defined by the IRS
- You are not enrolled in Medicare (with limited exceptions for certain Medicare Advantage HDHPs)
- You are not claimed as a dependent on someone else’s federal tax return
- You do not have any other disqualifying health coverage, as outlined in the previous section
The Medicare exception is a common point of confusion. If you are enrolled in Original Medicare (Part A and Part B), you cannot contribute to an HSA, even if you have a standalone HDHP. However, if you are enrolled in a Medicare Advantage HDHP, you may be able to make HSA contributions until you turn 65, or if you are still working and covered by the plan. It’s important to check with your plan administrator to confirm eligibility if you’re on Medicare.
Another often-overlooked rule is that you cannot contribute to an HSA after you enroll in Medicare, even if you are still working. The cutoff date for HSA contributions is the first day of the month you enroll in Medicare, so it’s important to plan ahead if you’re approaching Medicare eligibility. For example, if you enroll in Medicare on July 1, you can only contribute to your HSA for the first six months of the year, prorated based on your eligibility period.
Common Types of HSA-Eligible Plans You Might Encounter
Now that we’ve covered both plan and personal eligibility rules, let’s look at the most common types of HSA-eligible plans you might encounter as a consumer. Many people assume that only employer-sponsored plans qualify, but there are individual and family plans available too, each with their own benefits and drawbacks.
The four most common HSA-eligible plan types are laid out in the table below:
| Plan Type | Who It’s Offered To | HSA Eligibility Status |
|---|---|---|
| Employer-Sponsored HDHP | Full-time employees of companies that offer CDHPs | Eligible, if it meets IRS limits |
| Individual Market HDHP | Self-employed people or those without employer coverage | Eligible, if it meets IRS limits |
| High-Deductible Health Plan for Medicare Beneficiaries | People on Medicare Advantage who want an HSA | Eligible, with strict contribution limits |
| Student Health HDHP | College students who don’t have parental coverage | Eligible, if it meets IRS limits |
Employer-sponsored HDHPs are the most common, and many employers will even make contributions to your HSA on your behalf as part of their benefits package. According to the Kaiser Family Foundation, 29% of large employers offered HSA-eligible plans in 2023, up from 22% in 2018. That’s a steady growth trend that shows more employers are adopting these tax-advantaged plans.
Individual market HDHPs are another popular option, especially for self-employed workers or those who quit their jobs. These plans can be purchased through the Health Insurance Marketplace, and you can qualify for premium tax credits if your income falls within certain limits, even if you have an HSA-eligible plan. Just make sure that the plan you pick meets the 2024 IRS deductible and out-of-pocket maximums to keep your HSA eligibility intact.
How to Verify If Your Current Plan Is HSA-Eligible
Once you understand the rules of HSA-eligible plans, the next step is learning how to check if your current or prospective plan qualifies. Even if you think you have an HSA-eligible plan, it’s always a good idea to verify your status before making contributions. The last thing you want is to contribute to an HSA for a year, only to find out your plan doesn’t qualify and you have to pay back the contributions plus penalties.
There are four simple steps you can take to confirm your plan’s eligibility:
- Check your plan’s summary of benefits and coverage (SBC): This document, which all insurance plans must provide, will clearly state whether the plan is a qualifying HDHP.
- Contact your insurance provider or employer’s benefits administrator: They can confirm your plan’s eligibility and provide you with the exact deductible and out-of-pocket maximums for the year.
- Use the IRS’s official HSA eligibility tool: The IRS has a free online tool that can help you determine if your plan qualifies, based on your plan’s details.
- Check your HSA provider’s eligibility list: Most HSA custodians publish a list of approved plans that qualify for their accounts, so you can cross-reference your plan with that list.
It’s important to note that plan eligibility can change from year to year, even if you had an HSA-eligible plan in 2023. Your employer may switch to a different plan for 2024, or your individual market plan may be updated to no longer meet the IRS limits. That’s why it’s critical to verify your eligibility every year, usually during open enrollment season.
Another common mistake is assuming that a plan with an HSA logo is automatically eligible. Some insurance plans use the HSA logo to market themselves, but they may not actually meet the IRS requirements. Always double-check the details, don’t rely solely on the logo or marketing materials.
Penalties for Enrolling in a Non-Qualifying Plan With an HSA
Finally, let’s cover the serious consequences of using an HSA with a non-qualifying plan, to help you avoid costly mistakes. If you accidentally contribute to an HSA while enrolled in a non-qualifying plan, you could face serious penalties from the IRS. The penalties are designed to discourage people from using HSAs with plans that don’t meet the IRS rules, and they can add up quickly if you don’t correct the mistake.
The main penalties the IRS imposes for ineligible HSA contributions include:
- Income tax on the excess contributions: Any amount you contributed to the HSA that you’re not eligible for will be taxed as ordinary income in the year you made the contribution.
- 6% excise tax on excess contributions: If you don’t withdraw the excess contributions by the tax filing deadline (including extensions), you’ll have to pay a 6% excise tax on the excess amount every year until you withdraw it.
- Penalties for incorrectly claiming HSA deductions on your taxes: If you deduct your HSA contributions on your tax return and you’re not eligible, the IRS will disallow the deduction and add penalties and interest to your tax bill.
The good news is that you can correct these mistakes by withdrawing the excess contributions before the tax filing deadline. For example, if you contributed $3,000 to your HSA in 2024 but your plan wasn’t eligible, you can withdraw the $3,000 plus any earnings from the account by April 15, 2025, to avoid the 6% excise tax. It’s important to note that you’ll have to report the withdrawn amount as income on your 2024 tax return, however.
To avoid these penalties altogether, always verify your plan’s eligibility before making any HSA contributions, especially during open enrollment when you’re switching plans. Taking a few extra minutes to check your plan’s details can save you hundreds or even thousands of dollars in penalties down the line.
To wrap up, What Makes a Plan HSA Eligible boils down to three core sets of rules: the plan must be a qualifying HDHP that meets IRS annual limits, it cannot offer disqualifying first-dollar coverage, and you must meet personal eligibility criteria (like not being on Medicare or a dependent). Every year, thousands of people miss out on HSA tax savings or face costly penalties because they skip these verification steps, so taking the time to double-check your plan’s status is well worth the effort. Whether you’re shopping for a new plan during open enrollment or reviewing your current coverage, keep these rules top of mind to make the most of your HSA benefits.
If you’re ready to start exploring HSA-eligible plans for the 2024 tax year, start by pulling your current plan’s summary of benefits and coverage, or use the IRS’s free eligibility tool to run a quick check. If you need extra help, reach out to your employer’s benefits administrator or a licensed insurance agent who specializes in HSA-qualified plans. By making informed choices now, you can save thousands of dollars on taxes and medical costs in the year ahead.
