Health care costs can be unpredictable. Even with insurance, out-of-pocket expenses can add up quickly. If you’re enrolled in a high-deductible health plan, you may be looking for a smarter way to manage those costs and reduce your taxes along the way.
That’s where an HSA comes in. It’s a type of savings account that lets you set aside pre-tax dollars to pay for qualified medical expenses. For many individuals and families, an HSA offers flexibility, tax advantages, and long-term savings potential.
But how exactly does an HSA work? Is it the right fit for your health coverage and financial plans? This guide breaks down everything you need to know about HSAs so you can decide with confidence.
What Is an HSA?
A Health Savings Account (HSA) is a tax-advantaged account that helps individuals with high-deductible health plans (HDHPs) pay for qualified medical expenses. It allows you to set aside pre-tax dollars to cover costs like prescriptions, dental and vision care, lab tests, and doctor visits.
You can also use HSA funds for deductibles, copayments, and coinsurance. However, health insurance premiums generally do not qualify, with a few exceptions. These include:
✅ Long-term care insurance
✅ COBRA continuation coverage
✅ Health coverage during periods of unemployment
✅ Medicare premiums after age 65 (excluding Medigap)
HSAs are meant to offer flexibility and potential tax benefits, but only if you’re enrolled in an HSA-eligible HDHP.
How Does an HSA Work?
An HSA helps you save for current and future medical expenses using pre-tax dollars. This means you can lower your taxable income while building a cushion for qualified health care costs.
An HSA is individually owned, meaning, you control the account. Both you and your employer may contribute to it. Contributions made through payroll are excluded from your income. If you contribute on your own, you may deduct the amount directly on your federal tax return (above the line).
HSAs offer three key tax benefits:
✅ Contributions are tax-deductible
✅ Earnings from interest or investments grow tax-free
✅ Withdrawals for qualified medical expenses are tax-free
How the Account Grows
You may keep HSA funds in a basic interest-bearing account, or you may invest them, depending on the HSA provider. Earnings stay tax-free while in the account, and can be reinvested without triggering taxes.
Withdrawals and Flexibility
Withdrawals used for qualified medical expenses are tax-free at any age. Once you reach age 65 or become disabled, you may also withdraw money for non-medical expenses without the 20% penalty. However, those non-medical withdrawals are taxed as ordinary income.
This setup allows your HSA to act like a health care safety net, with potential to grow over time for both immediate needs and future medical costs.

What Health Care Expenses Are Eligible?
An HSA can be used to pay for a wide range of qualified medical expenses. These typically include doctor visits, prescriptions, dental procedures, and vision care.
Beyond routine care, your HSA may also cover:
✅ First aid supplies and medical equipment – such as bandages, ointments, wheelchairs, and crutches
✅ Health monitoring tools – including blood pressure monitors, glucometers, and test strips
✅ Feminine hygiene products – including tampons and pads
✅ Eye care – like exams, glasses, and contact lenses
✅ Complementary therapies – acupuncture and chiropractic care usually qualify; massage therapy may qualify when prescribed for a medical condition
✅ Substance use treatment – including certain addiction programs
✅ Fertility and maternity expenses – such as IVF, breast pumps, and lactation supplies
✅ Dependent care – medical expenses for your children or qualified dependents, even if they are not enrolled in your health plan
✅ Certain home improvements – if medically necessary (e.g., wheelchair ramps), a portion of the cost may qualify when it doesn’t increase the home’s value
📝 Note: HSA-qualified expenses must meet IRS criteria. You can review the full list in IRS Publication 502, though not every expense listed there is HSA-eligible.
As long as you use the funds for qualified expenses, withdrawals from your HSA remain tax-free.
Who Is Eligible for an HSA?
You may open an HSA if you meet all of the following conditions:
✅ You are covered by a high-deductible health plan (HDHP)
✅ You have no other health coverage, including certain types of supplemental plans
✅ You are not enrolled in Medicare
✅ You are not claimed as a dependent on someone else’s tax return
An employer may offer an HDHP with HSA access, but it’s not required. You can also open an HSA on your own if you meet the eligibility rules.
Employer Contributions
Employers may choose to contribute to employees’ HSAs, but they are not required to match employee contributions. If they do contribute, they must follow IRS comparability rules, which require the same contribution amount or percentage for all eligible employees in the same category.
Self-Employed Workers
If you’re self-employed, you may open an HSA through most banks, brokerages, or credit unions, as long as you are enrolled in an HSA-eligible HDHP.
What Counts as a High-Deductible Health Plan?
An HDHP is a type of insurance plan that typically has lower monthly premiums but higher deductibles than traditional plans. To qualify for HSA eligibility, the plan must meet the IRS minimum deductible and maximum out-of-pocket limit, which change each year.
For 2025, an HDHP must meet the following thresholds:
| Coverage Type | Minimum Deductible | Out-of-Pocket Limit |
| Individual | $1,650 | $8,300 |
| Family | $3,300 | $16,600 |
📌 Source: Rev. Proc. 2024-25: 2025 HSA and HDHP inflation-adjusted amounts
For comparison, the 2024 thresholds were $1,600 (individual) / $3,200 (family) for deductibles and $8,050 / $16,100 for out-of-pocket limits.
These numbers mean you must generally pay medical expenses out of pocket until you reach the deductible, after which your insurance coverage begins. Once you hit the out-of-pocket cap, the insurer typically covers 100% of additional eligible costs.
HSA Contribution Limits and Deadlines
Contribution Limits for 2025
For the 2025 tax year, the IRS allows the following HSA contribution limits:
| Coverage Type | Contribution Limit |
| Individual Plan | $4,300 |
| Family Plan | $8,550 |
If you are age 55 or older, you may contribute an additional $1,000 as a catch-up contribution.
Both employee and employer contributions count toward the annual limit. This means the combined total from all sources must stay within the IRS limit for your coverage type.
📝 Note: If you contribute more than the allowed amount, the excess is subject to a 6% excise tax, unless withdrawn before the tax filing deadline.

Contribution Deadline
You may contribute to your HSA up until the federal tax filing deadline for the year. For most people, this falls on April 15, unless that day lands on a weekend or federal holiday. In those cases, the deadline shifts to the next business day.
HSA Withdrawal Rules
You may withdraw money from your HSA at any time. If the funds are used for qualified medical expenses, the withdrawal is completely tax-free.
However, using your HSA for non-medical expenses before age 65 triggers two types of taxes:
❌ A 20% penalty tax on the amount withdrawn
❌ Ordinary income tax on the full amount
After you turn age 65 or if you become disabled, you may take withdrawals for any purpose without the 20% penalty. In that case, non-medical withdrawals are simply taxed as ordinary income, similar to a traditional 401k or IRA distribution.
📝 Note: Qualified withdrawals remain tax-free at any age, as long as they are used for eligible medical expenses.
HSA Pros and Cons
HSAs offer unique tax treatment and flexibility, but they also come with certain eligibility rules and restrictions. Here’s a closer look at the potential benefits and trade-offs:
Pros
✅ Broad coverage of eligible expenses – HSAs can be used for many qualified medical costs, including doctor visits, prescriptions, vision, dental, and more.
✅ Others can contribute on your behalf – In addition to your own contributions, employers, family members, or anyone else may add funds to your account.
✅ Contributions reduce taxable income – Amounts you contribute are tax-deductible, which can lower your federal income taxes.
✅ Tax-free earnings and investment growth – Interest and investment earnings inside the account are not taxed, as long as they remain in the HSA.
✅ Tax-free withdrawals for medical expenses – Qualified medical withdrawals are never taxed, even though contributions were made pre-tax.
✅ The account stays with you – HSA funds are individually owned and portable. If you change jobs or health plans, your HSA remains yours.
Cons
❌ You must be enrolled in a high-deductible health plan (HDHP) – These plans often come with higher out-of-pocket costs, which could be a financial burden if you need major care.
❌ Early non-medical withdrawals are penalized – If you use HSA funds for non-medical purposes before age 65, you’ll face a 20% penalty plus ordinary income tax.
❌ Non-medical use is always taxed – After age 65, the 20% penalty no longer applies, but non-medical withdrawals are still taxed as ordinary income.
Wrapping It Up
An HSA offers a flexible way to set aside money for medical expenses while potentially lowering your tax burden. It’s designed for individuals with high-deductible health plans, and it may be useful for those who want to cover immediate health care costs or save for future medical needs.
If you’re eligible, review your current health plan and estimate your annual out-of-pocket expenses to determine whether an HSA makes sense for your situation. Keep in mind the contribution limits, tax rules, and withdrawal guidelines, and consider speaking with a qualified professional if you’re unsure how to align an HSA with your broader financial or retirement goals.
