Health Savings Accounts (HSAs) are a powerful tool for managing healthcare costs while enjoying tax benefits. To qualify, you need to meet specific IRS rules, including enrollment in a High Deductible Health Plan (HDHP). Here’s what you need to know:
- Triple Tax Advantage: Contributions reduce taxable income, growth is tax-free, and withdrawals for medical expenses aren’t taxed.
- 2025 Contribution Limits: $4,300 for individuals, $8,550 for families, plus a $1,000 catch-up for those 55+.
- Eligibility Rules:
- Must have an HDHP with a minimum deductible of $1,650 (individual) or $3,300 (family).
- Cannot be enrolled in Medicare or claimed as a dependent.
- Certain coverage types (like general FSAs) can disqualify you.
- Key Features:
- Funds roll over yearly and stay with you, even if you change jobs or health plans.
- After age 65, funds can be withdrawn for any purpose (non-medical withdrawals are taxed as income).
HSAs offer flexibility for both short-term medical expenses and long-term savings, but staying compliant with IRS rules is crucial to avoid penalties. For 2025, the maximum out-of-pocket limits for HDHPs are $8,300 (individual) and $16,600 (family). Use your HSA to cover a wide range of qualified medical expenses, from doctor visits to prescription medications.
Pro Tip: If you’re eligible on December 1, you can contribute the full annual limit under the "last-month rule", but ensure you remain eligible for the following 12 months to avoid penalties.

HSA Eligibility Requirements
To enjoy the tax benefits of a Health Savings Account (HSA), you must meet the criteria set by the IRS.
High Deductible Health Plan (HDHP) Requirement
The foundation of HSA eligibility is being enrolled in a High Deductible Health Plan (HDHP). However, not all high-deductible plans qualify – you’ll need a plan that meets the IRS standards for 2025.
Recent updates to budget laws have expanded eligibility to include ACA Catastrophic and Bronze Plans. Additionally, new telehealth provisions allow HDHPs to cover telehealth services before the deductible is met, without affecting HSA eligibility.
| Coverage Type | Minimum Deductible (2025) | Maximum Out-of-Pocket (2025) |
|---|---|---|
| Individual | $1,650 | $8,300 |
| Family | $3,300 | $16,600 |
Other IRS Eligibility Rules

In addition to having an HDHP, several other IRS rules determine your eligibility. For instance, if you are enrolled in Medicare, you can no longer contribute to an HSA, though you can still use the funds for qualified expenses. Similarly, if someone else claims you as a dependent on their tax return, you are not eligible to open or contribute to an HSA.
Certain types of health coverage can also impact eligibility. While most other health insurance plans disqualify you, there are exceptions for "permitted insurance" plans, such as specific disease coverage, accident insurance, or VA-provided coverage for service-connected disabilities. However, you cannot contribute to both an HSA and a general-purpose Health FSA. If you need an FSA, only a Limited Purpose FSA for dental and vision expenses is allowed.
Last-Month Rule Explained
The last-month rule offers a way to maximize your HSA contributions. If you are eligible for an HSA on December 1 of any year, the IRS considers you eligible for the entire year, allowing you to contribute the full annual limit.
However, there’s a catch: you must remain eligible throughout the following 12-month testing period to keep the tax benefits. If you lose eligibility during this period after making the full contribution, the excess amount becomes taxable, and a 10% penalty applies. These details are reported on IRS Form 8889. To avoid penalties, ensure you maintain eligibility for the entire testing period.
For those in Illinois who need help navigating these rules, Illinois Health Agents can provide expert advice on choosing HSA-eligible HDHPs and staying compliant with IRS regulations. Their guidance can help you avoid costly errors and get the most out of your HSA.
2025 HSA Contribution Limits and Tax Benefits
Understanding the 2025 HSA limits and tax perks can help you save more and reduce your tax burden.
2025 Contribution Limits
For 2025, the IRS has set the HSA contribution limits at $4,300 for individuals with self-only coverage and $8,550 for those with family coverage. These limits are slightly higher than the 2024 limits, which were $4,150 for individuals and $8,300 for families.
If you’re 55 or older and not enrolled in Medicare, you can take advantage of an additional $1,000 catch-up contribution. This means your total contribution could reach $5,300 for self-only coverage or $9,550 for family coverage.
It’s important to note that employer contributions count toward your annual limit. For example, if you have self-only coverage and your employer contributes $1,000, you can personally contribute up to $3,300 to reach the $4,300 limit. If you’re eligible for the $1,000 catch-up contribution, your total personal contribution can go up to $4,300, allowing you to reach an overall limit of $5,300.
| Coverage Type | 2025 Contribution Limit | Catch-Up (Age 55+) | Total Possible |
|---|---|---|---|
| Self-only | $4,300 | +$1,000 | $5,300 |
| Family | $8,550 | +$1,000 | $9,550 |
HSA Tax Benefits
HSAs come with three key tax advantages:
- Pre-tax contributions: Contributions made with pre-tax dollars reduce your taxable income. If you contribute after-tax income, those contributions are tax-deductible.
- Tax-free growth: Any interest or investment gains within your HSA grow tax-free, unlike taxable accounts where gains are subject to taxes.
- Tax-free withdrawals: When you use HSA funds for qualified medical expenses, you don’t pay any taxes on the withdrawals.
Here’s a practical example: If you contribute the maximum $4,300 for self-only coverage and are in the 22% tax bracket, you’ll save $946 in federal taxes immediately. On top of that, any growth in your account remains untaxed, and withdrawals for eligible medical expenses are completely tax-free.
Qualified Medical Expenses
Qualified medical expenses include a wide range of IRS-approved healthcare costs. These can cover routine expenses like doctor visits, prescription medications, eyeglasses, dental procedures, and even some medical equipment. Additionally, HSA funds can be used for services like acupuncture, chiropractic care, and certain medical devices – all without tax penalties.
For a complete list of eligible expenses, visit IRS.gov.
Be cautious with non-qualified expenses. If you use HSA funds for non-medical purposes, the withdrawal will be subject to regular income tax plus a 20% penalty. For example, withdrawing $1,000 for a non-qualified expense in a 22% tax bracket would result in $220 in taxes and a $200 penalty.
After age 65, the 20% penalty no longer applies, but withdrawals for non-medical expenses will still be taxed as regular income. This makes HSAs a flexible tool for retirement savings while maintaining their tax-free benefits for medical expenses at any age.

How to Maintain HSA Eligibility
Maintaining your Health Savings Account (HSA) eligibility requires careful attention to your health coverage and any personal changes that might affect your status. Even small shifts in your circumstances can disqualify you from contributing and lead to the loss of tax benefits. Below, we’ll explore what can impact your eligibility, the penalties for non-compliance, and some practical ways to stay on track.
What Can Impact Your Eligibility
Certain life events or changes in coverage can make you ineligible to contribute to your HSA. For instance, enrolling in any part of Medicare will disqualify you from making new contributions to the account. However, you can still use the funds you’ve already saved to pay for qualified expenses like Medicare premiums or out-of-pocket healthcare costs.
Switching away from a High Deductible Health Plan (HDHP) also means you’re no longer eligible. This applies whether you move to a traditional PPO or HMO plan, whether through your employer or the individual market. Even short gaps in HDHP coverage can affect how much you’re allowed to contribute.
If someone else claims you as a dependent on their tax return, you won’t be able to make HSA contributions – even if you have your own HDHP. This situation can often affect young adults who are still listed as dependents by their parents, despite having qualifying coverage.
Additionally, if your spouse has a non-HDHP family plan that also covers you, you lose your eligibility to contribute. However, if the plan only covers your spouse and not you, your eligibility remains intact.
Tax Penalties for Non-Compliance
The IRS takes HSA compliance seriously, and breaking the rules can result in steep penalties. If you contribute more than the annual limit, you’ll face a 6% excise tax on the excess amount each year it remains in the account. The "last-month rule" can also lead to complications. If you lose eligibility during the testing period, the excess contributions become taxable, and you’ll incur an additional 10% penalty.
For example, let’s say you became eligible on December 1, 2024, and contributed the full family limit of $8,550 under the last-month rule. If you lose eligibility in June 2025, the excess contributions would be added to your 2025 taxable income, and you’d face a 10% penalty on top of your regular income taxes.
Using HSA funds for non-qualified expenses before age 65 comes with its own penalties. You’ll owe regular income tax on the amount you withdrew, plus an additional 20% penalty. After age 65, the 20% penalty no longer applies, but you’ll still owe income tax on any non-medical withdrawals.
Tips for Staying Compliant
To avoid losing your HSA eligibility or facing penalties, it’s important to stay proactive. Here are some strategies to help you stay on track:
- Review your health coverage regularly. During open enrollment or when your employer changes plans, confirm that your coverage remains HSA-qualified.
- Monitor your contributions. Keep an eye on how much you’ve contributed to avoid exceeding the annual limit. Don’t forget that employer contributions count toward this limit. For example, if your employer adds $1,000 to your account and the individual limit is $4,300, you can only contribute $3,300 from your own funds.
- Plan for major life changes. If you’re nearing Medicare eligibility, consider maximizing your HSA contributions beforehand, as enrolling in Medicare disqualifies you from contributing further. Similarly, if you’re switching jobs, check that your new employer’s health plan meets HDHP requirements.
- Document everything. Since eligibility is calculated on a month-by-month basis, keeping accurate records of your coverage periods and contribution dates is essential. For instance, if you’re only eligible for six months of the year, you can only contribute up to half of the annual limit.
- Set reminders for key dates. If you’re using the last-month rule, mark December 1 on your calendar, as well as the end of your testing period, to ensure you stay compliant. Scheduling an annual consultation with a tax professional can also help you catch potential issues early.

Conclusion
Health Savings Accounts (HSAs) are an impressive savings tool that offers a unique combination of tax benefits. They allow you to reduce your taxable income, enjoy tax-free growth, and make withdrawals without taxes for qualified medical expenses. For example, a family contributing the maximum allowed in 2025 could save over $2,000 in federal taxes if they’re in the 24% tax bracket. However, these advantages come with strict rules that must be followed to remain eligible.
To qualify for an HSA, you need to meet the IRS requirements, such as being covered by a High Deductible Health Plan (HDHP) and avoiding disqualifying coverage. Breaking these rules – like violating the last-month rule – can lead to taxable excess contributions and even a 10% penalty.
The real key to getting the most out of your HSA is understanding both its benefits and its limitations. Regularly reviewing your coverage and contributions can help you maximize savings while staying compliant. If you’re in Illinois and need tailored guidance, check out Illinois Health Agents.
With careful planning and a clear understanding of the rules, an HSA can be more than just a way to handle current medical costs – it can grow into a long-term investment. Over time, it could help you cover healthcare expenses in the future or even supplement your retirement income once you reach age 65.
FAQs
What happens if I lose my HSA eligibility during the testing period after using the last-month rule?
If you lose your HSA eligibility during the testing period after applying the last-month rule, you could face tax consequences. The IRS requires that you stay eligible throughout the testing period, which begins on December 1 of the year you used the last-month rule and continues through December 31 of the following year. Losing eligibility during this time means the contributions made under the last-month rule no longer qualify as tax-free.
When this happens, the ineligible contributions are added to your taxable income for the year your eligibility ended. On top of that, you might also be hit with a 10% penalty on those amounts. To steer clear of these penalties, it’s crucial to ensure you meet the eligibility requirements for the entire testing period. If you’re unsure about your HSA or health insurance options, Illinois Health Agents can offer personalized advice tailored to your situation.
Can I use my HSA funds for non-medical expenses after I turn 65, and will I have to pay taxes?
Once you hit 65, you’re allowed to use your HSA funds for non-medical expenses without facing a penalty. However, keep in mind that these withdrawals will be taxed as ordinary income, much like distributions from a traditional IRA or 401(k). On the other hand, if you stick to using your HSA for qualified medical expenses, those withdrawals stay tax-free, which can be a big financial perk.
How do employer contributions impact my HSA contribution limit for 2025?
Employer contributions to your Health Savings Account (HSA) are included in the annual contribution limit set by the IRS. For 2025, this limit combines both your personal contributions and any amount your employer adds. For instance, if the individual limit is $4,150 and your employer contributes $1,000, you can contribute up to $3,150 on your own.
Keeping track of these contributions is crucial because exceeding the limit could result in penalties. If you’re looking for help to make the most of your HSA or need clarity on contribution limits, Illinois Health Agents is available to guide you through your health insurance options and HSA eligibility.
