A Health Savings Account, or HSA, is a tax-advantaged account that eligible individuals can use to save and pay for qualified medical expenses. Unlike a health insurance policy, an HSA is an account that belongs to you. Money can remain in the account from year to year, the balance can potentially earn interest or investment returns depending on the provider, and the account generally stays with you when you change employers. HSAs can provide significant federal tax advantages, but contribution eligibility depends on your health coverage and other requirements.

How Does a Health Savings Account Work?
An HSA generally has two separate parts to understand: contributions and distributions.
If you satisfy the federal eligibility rules, money can be contributed to your HSA by you, your employer, or another person on your behalf, subject to the annual contribution limit.
You can then use money from the account to pay or reimburse qualified medical expenses. A qualifying distribution is generally not included in federal taxable income.
You are not required to empty the account each year. Money you do not spend generally remains available for future years.
Contribute money → Keep it in the HSA → Pay or reimburse qualified medical expenses tax-free when eligible
The Three Main Federal Tax Advantages of an HSA
1. Tax-Favored Contributions
Eligible contributions you make yourself can generally be deducted from federal taxable income even if you do not itemize deductions.
Qualifying employer contributions, including qualifying salary-reduction contributions through a cafeteria plan, can generally be excluded from federal gross income.
2. Tax-Free Growth
Interest and other earnings inside an HSA generally are not included in federal taxable income while they remain in the account.
3. Tax-Free Qualified Withdrawals
Distributions used exclusively for qualified medical expenses can generally be excluded from federal taxable income.
Federal and state tax treatment can differ: The rules discussed here primarily describe federal HSA taxation. Check applicable state tax rules when evaluating the full tax benefit.
2026 HSA Contribution Limits
The IRS adjusts HSA contribution limits periodically for inflation.
| 2026 HSA Contribution Rule | Limit |
|---|---|
| Self-only coverage | $4,400 |
| Family coverage | $8,750 |
| Additional contribution for an eligible individual age 55 or older | $1,000 |
The limit generally includes contributions from all sources, including contributions you make, qualifying employer contributions, and contributions another person makes on your behalf.
Illustrative Contribution Example
Assume you have self-only HSA-eligible coverage for all of 2026 and your employer contributes $1,000 to your HSA.
2026 self-only limit: $4,400.
$4,400 − $1,000 employer contribution = $3,400 remaining contribution capacity, assuming no other contributions and full-year eligibility.
This example is simplified. Partial-year eligibility and other rules can change the allowable amount.
Who Is Eligible to Contribute to an HSA?
Having an HSA account and being allowed to make new contributions are two different things.
Under the general federal rules, to qualify as an eligible individual for a particular month, you generally must:
- Have qualifying HSA-compatible coverage.
- Not have other disqualifying health coverage, subject to permitted exceptions.
- Not be enrolled in Medicare.
- Not be eligible to be claimed as another person’s tax dependent under the applicable HSA rule.
Eligibility is generally determined month by month, although special rules such as the last-month rule can affect how much a person is permitted to contribute.
What Health Insurance Works With an HSA?
Traditionally, HSA contributions have required coverage under a qualifying high-deductible health plan, or HDHP.
For 2026, the general IRS HDHP thresholds are:
| 2026 General HDHP Requirement | Self-Only | Family |
|---|---|---|
| Minimum deductible | $1,700 | $3,400 |
| Maximum annual out-of-pocket expenses | $8,500 | $17,000 |
However, 2026 introduced important additional HSA-compatible coverage rules.
New for 2026: Bronze and Catastrophic Plans
Beginning January 1, 2026, federal law treats qualifying Bronze and Catastrophic individual plans available through an Exchange as HDHPs for HSA purposes.
HealthCare.gov therefore states that all Bronze and Catastrophic Marketplace plans work with HSAs in 2026, while some plans in other categories can also be designated HSA-eligible.
This means a plan can qualify under the special 2026 rule even if it does not satisfy the traditional HDHP deductible and out-of-pocket thresholds described above.
HSA vs. HDHP
An HSA and an HDHP are not the same thing.
| Term | What It Is |
|---|---|
| HDHP | A health insurance plan meeting applicable HSA-compatible requirements. |
| HSA | A tax-advantaged account used to save and pay qualified medical expenses. |
Your health plan provides insurance coverage. Your HSA holds money that can help you pay your portion of eligible health costs.
Who Can Contribute Money to an HSA?
Contributions can potentially come from:
- You.
- Your employer.
- A family member.
- Another person contributing on your behalf.
All applicable contributions generally count toward your annual limit regardless of who supplies the money.
Employer HSA Contributions
Some employers contribute money to employees’ HSAs as part of their benefits package.
An employer contribution can make an HSA-compatible health plan financially more attractive because it gives the employee money that can be used toward qualified expenses or preserved for future medical costs.
Illustrative Employer Contribution Example
Assume an employer offers an HSA-compatible plan and contributes $1,500 per year to the employee’s HSA.
If the competing health plan has no employer-funded account, that $1,500 should be included when comparing the financial value of the two options.
However, the employer contribution still counts toward the annual HSA contribution limit.
HSA Catch-Up Contributions After Age 55
An eligible individual who is age 55 or older at the end of the tax year can generally increase the HSA contribution limit by $1,000.
If both spouses are eligible and age 55 or older, each spouse must make their own catch-up contribution to their own HSA. HSAs cannot be jointly owned.
Can Married Couples Share an HSA?
No. An HSA is individually owned.
A married couple can each have an HSA if each spouse is eligible, but there is no jointly owned family HSA.
Special contribution-allocation rules can apply when spouses have family HSA-compatible coverage, particularly when both spouses are eligible and both maintain accounts.
What Can You Pay for With an HSA?
HSA funds can generally be withdrawn tax-free for unreimbursed qualified medical expenses as defined under federal tax law.
Depending on the expense and applicable rules, qualifying costs can include:
- Health insurance deductibles.
- Copayments.
- Coinsurance.
- Doctor and specialist expenses.
- Hospital expenses.
- Prescription medications.
- Certain over-the-counter medicines.
- Certain dental expenses.
- Certain vision expenses.
- Certain medical equipment and supplies.
- Menstrual care products.
- Other expenses qualifying as medical care under federal tax rules.
The expense generally must not already have been reimbursed by insurance or another source.
Can You Use Your HSA for Your Spouse or Children?
Generally, yes, when the person satisfies the applicable relationship and dependency rules.
Qualified HSA medical expenses can generally include qualifying expenses incurred for:
- You.
- Your spouse.
- Dependents who satisfy applicable federal rules.
- Certain individuals who could qualify as dependents except for specified tax-rule exceptions.
The rules for whose expenses qualify are separate from the rules determining who is personally eligible to contribute to an HSA.
Expenses Incurred Before the HSA Was Established
An important limitation is that medical expenses generally must be incurred after your HSA is established in order to qualify for tax-free HSA reimbursement.
Simply enrolling in an HSA-compatible health plan does not necessarily mean the HSA account itself has already been established.
Can You Reimburse Yourself Later?
Under longstanding IRS guidance, there generally is no federal time limit requiring you to reimburse yourself from the HSA immediately after paying a qualified medical expense.
For example, you could potentially pay a qualifying medical bill with ordinary cash today, preserve the receipt, and reimburse yourself from the HSA in a later year, provided the expense occurred after the HSA was established and it was not previously reimbursed or deducted.
Keep documentation: Delayed reimbursement depends heavily on your ability to demonstrate that the expense qualified, was incurred after the HSA was established, and was not reimbursed or deducted elsewhere.
Can HSA Money Pay Health Insurance Premiums?
Ordinary health insurance premiums generally are not qualified HSA medical expenses.
Federal rules provide important exceptions that can include certain premiums for:
- Qualified long-term care insurance, subject to applicable limits.
- COBRA and certain other continuation coverage.
- Health coverage while receiving federal or state unemployment compensation.
- Medicare and certain other health coverage after age 65, subject to applicable rules and excluding Medigap premiums.
What Happens if You Use HSA Money for Nonmedical Expenses?
You can generally take money from an HSA at any time, but the tax treatment depends on how you use it.
A withdrawal not used for qualified medical expenses is generally included in federal taxable income.
Before age 65, the taxable nonqualified amount generally also faces an additional 20% federal tax unless another exception applies.
Illustrative Nonqualified Withdrawal
Assume a person under age 65 takes $2,000 from an HSA for a nonmedical purchase and no exception applies.
The $2,000 would generally be included in taxable income, and the additional federal tax could be:
$2,000 × 20% = $400 additional tax, in addition to ordinary income tax. The example is simplified.
What Changes After Age 65?
Once you reach age 65, the additional 20% tax generally no longer applies to HSA distributions.
Qualified medical withdrawals can still generally be tax-free.
Nonmedical withdrawals generally remain taxable as ordinary income, but they are not generally subject to the additional 20% tax after age 65.
Medicare and HSA Contributions
You generally cannot make HSA contributions for months in which you are enrolled in Medicare.
However, Medicare enrollment does not cause you to lose the money already in your HSA. You can continue using existing HSA funds for qualified medical expenses.
People approaching Medicare enrollment should review contribution timing carefully because Medicare coverage can sometimes have a retroactive effective date.
What if You Stop Being HSA-Eligible?
Losing eligibility to make new contributions does not automatically close your existing HSA.
For example, you might move to a non-HSA-compatible health plan. In that case, you generally stop making new contributions for months you are ineligible, but the existing account balance remains yours.
You can generally continue taking tax-free distributions for qualified medical expenses even when you are no longer eligible to make HSA contributions.
HSA Money Rolls Over
One of the major differences between an HSA and some other health spending arrangements is that unused HSA money generally remains in the account.
There is no general requirement to spend your HSA balance by December 31.
Unused HSA balance this year → Remains available in future years
An HSA Is Portable
Your HSA generally belongs to you rather than your employer.
You generally keep it if you:
- Change employers.
- Lose your job.
- Become self-employed.
- Leave the workforce.
- Change health plans.
- Later enroll in Medicare.
Changing health plans can affect whether you may make new contributions, but it does not ordinarily transfer ownership of money already in the HSA to your employer.
Can You Transfer an HSA to Another Provider?
HSA assets can generally be moved between qualifying HSA trustees or custodians.
A direct trustee-to-trustee transfer is generally not treated as a taxable distribution or a new deductible contribution.
Someone might consider changing HSA providers because of differences in:
- Monthly fees.
- Investment options.
- Cash interest rates.
- Minimum balance requirements.
- Debit-card features.
- Customer service.
- Account administration.
HSA vs. FSA
A Health Savings Account and a health Flexible Spending Arrangement can both receive favorable federal tax treatment, but they are different structures.
| Feature | HSA | Health FSA |
|---|---|---|
| Ownership | Generally owned by the individual. | Generally employer-sponsored arrangement. |
| Unused money | Generally rolls over indefinitely. | Forfeiture, carryover, or grace-period rules depend on the plan and applicable limits. |
| Changing jobs | Account generally stays with the individual. | Generally tied to the employer plan. |
| Eligibility | Requires HSA eligibility to make contributions. | Depends on employer offering and plan eligibility. |
Having a general-purpose health FSA can affect HSA eligibility: Some additional health coverage can be disqualifying. Limited-purpose or post-deductible arrangements can operate differently, so review the actual plan structure.
HSA vs. HRA
| Feature | HSA | HRA |
|---|---|---|
| Who funds it? | Employee, employer, or others, subject to limits. | Employer. |
| Ownership | Individual account. | Employer-funded reimbursement arrangement. |
| Portability | Generally stays with the individual. | Rights depend on the employer arrangement. |
How to Open an HSA
You do not need special IRS approval to establish an HSA.
An HSA can generally be established with a qualified trustee or custodian such as:
- A bank.
- A credit union or financial institution offering qualifying HSA services.
- An insurance company or other qualifying trustee.
- A provider associated with your employer or health insurer.
Your HSA custodian does not necessarily need to be the same company that provides your health insurance.
What to Compare Between HSA Providers
- Monthly maintenance fees.
- Opening or closing fees.
- Debit-card access.
- Online bill payment.
- Cash interest rates.
- Investment availability.
- Investment fees.
- Minimum cash balance requirements.
- Transfer fees.
- Customer service and recordkeeping tools.
Can an HSA Be Invested?
Some HSA providers allow account holders to invest some or all of the balance once provider-specific requirements are met.
Investment options and minimum cash requirements vary significantly by provider.
Investing HSA funds can potentially increase long-term growth, but investment values can fluctuate. Money needed for near-term medical bills may require a different risk approach from money intended for expenses many years in the future.
2026 Direct Primary Care Rules
Beginning in 2026, federal law allows qualifying direct primary care service arrangements to coexist with HSA eligibility under specified conditions.
For 2026, the aggregate monthly fee generally cannot exceed $150 for an individual or $300 for an arrangement covering more than one individual for the arrangement to fall within the special rule.
Federal law also allows HSA money to be used for qualifying direct primary care arrangement fees under the new provision.
Not every membership-style medical arrangement qualifies as a direct primary care service arrangement, so the actual structure and services matter.
Telehealth and HSA Eligibility
Federal law now permanently allows qualifying telehealth and other remote-care services to be provided before the HDHP deductible without automatically destroying HSA eligibility.
The permanent rule applies for plan years beginning on or after January 1, 2025.
When Can You Make HSA Contributions?
Contributions for a tax year can generally be made during that year and through the unextended federal income tax filing deadline for that year.
When making a contribution after December 31 but before the applicable deadline, make sure the HSA provider knows which tax year the contribution is intended for.
Partial-Year HSA Eligibility
Someone who is eligible for only part of the year may have a reduced contribution limit.
A special last-month rule can sometimes allow a person who becomes eligible late in the year to contribute more than a simple monthly calculation would permit, but that rule includes a testing period and potential tax consequences if eligibility does not continue as required.
People changing coverage during the year should therefore calculate their actual contribution limit rather than automatically contributing the annual maximum.
What Happens if You Contribute Too Much?
Contributing more than your permitted HSA limit can create an excess contribution.
Excess contributions generally are not deductible and can be subject to a 6% federal excise tax for each year the excess remains in the account, unless properly corrected under applicable rules.
Employer contributions and other contributions must be included when determining whether the annual limit has been exceeded.
HSA Tax Forms
Common forms associated with HSAs include:
| Form | General Purpose |
|---|---|
| Form 8889 | Used with the federal income tax return to report HSA contributions and distributions and calculate applicable deductions or taxes. |
| Form 1099-SA | Generally reports HSA distributions. |
| Form 5498-SA | Generally reports HSA contribution information from the trustee or custodian. |
Keep HSA Receipts and Records
The HSA custodian generally reports how much money left the account, but it is your responsibility to support the tax treatment of the withdrawal.
IRS guidance says you should keep records showing that:
- The distribution was used for qualified medical expenses.
- The expense was not previously reimbursed by insurance or another source.
- The same expense was not also taken as an itemized medical deduction.
What Happens to an HSA When the Owner Dies?
HSA owners should designate a beneficiary.
If the surviving spouse is the designated beneficiary, the account generally becomes the surviving spouse’s HSA.
If the beneficiary is not the surviving spouse, the account generally stops being an HSA at death and the fair market value generally becomes taxable to the beneficiary, subject to applicable rules and adjustments.
Beneficiary designations should therefore be reviewed after marriage, divorce, remarriage, deaths, and other major family changes.
Who Might Benefit From an HSA?
An HSA can be particularly attractive if you:
- Already prefer an HSA-compatible health plan.
- Receive employer HSA contributions.
- Want to reduce current federal taxable income through eligible contributions.
- Want money set aside specifically for medical expenses.
- Can afford to leave some HSA money unused for future health costs.
- Want an account that follows you between employers.
- Want unused balances to roll over rather than expire annually.
- Expect substantial health expenses later in life and want to accumulate dedicated medical savings.
When an HSA-Compatible Plan May Be Less Attractive
The tax advantages of an HSA do not automatically make the associated health plan the best choice.
Another plan can be preferable if:
- You expect frequent medical care.
- You use expensive prescriptions.
- You would struggle to cover a large deductible.
- A lower-deductible plan has significantly better cost sharing.
- Your preferred doctors or hospitals are not in the HSA-compatible plan’s network.
- The premium savings are too small to compensate for the additional cost exposure.
Choose the health plan first based on total financial and medical value, then evaluate the HSA benefits that come with the qualifying option.
Common HSA Mistakes
Assuming an HSA Is Health Insurance
An HSA is a financial account. It does not replace health insurance coverage.
Assuming Every High-Deductible Plan Is HSA-Eligible
HSA eligibility depends on federal requirements or special qualifying rules, not simply whether the deductible is large.
Forgetting Employer Contributions Count Toward the Limit
Your own contribution capacity generally decreases when your employer contributes money to the same HSA.
Contributing After Medicare Enrollment
Medicare enrollment generally ends HSA contribution eligibility for the covered months, although the existing account remains usable.
Using HSA Money for Nonqualified Expenses Before 65
The withdrawal can become taxable and may also face the additional 20% federal tax.
Throwing Away Medical Receipts
Receipts and supporting records are important for proving that withdrawals were tax-free qualified distributions.
Assuming HSA Money Expires
HSA balances generally remain available from year to year.
Ignoring Account Fees
Administrative and investment fees can reduce the long-term value of a small HSA balance.
Contributing the Full Annual Maximum Without Checking Partial-Year Eligibility
Coverage changes, Medicare enrollment, other insurance, or dependency status can reduce the permitted contribution amount.

Frequently Asked Questions
The Bottom Line
A Health Savings Account is a tax-advantaged account that can help eligible individuals save for current and future medical expenses. It is separate from health insurance and belongs to the account holder.
For 2026, eligible individuals can generally contribute up to $4,400 with self-only coverage or $8,750 with family coverage, plus a $1,000 catch-up contribution when age 55 or older and otherwise eligible. Employer contributions count toward those limits.
The account’s major federal tax advantages come from tax-favored contributions, tax-free growth, and tax-free distributions for qualified medical expenses. Unused money generally rolls over indefinitely, and the account stays with you when you change employers.
Eligibility rules remain important. You generally need HSA-compatible coverage, cannot have disqualifying additional coverage, cannot contribute for months enrolled in Medicare, and cannot qualify for contributions when disqualified under the tax-dependent rule. Beginning in 2026, qualifying Bronze and Catastrophic individual plans receive expanded HSA-compatible treatment.
Finally, an HSA is most valuable when it is coordinated with the right health plan. Compare premiums, deductibles, out-of-pocket exposure, employer contributions, provider networks, prescription coverage, your available savings, and expected health care use before choosing coverage simply because it offers HSA access.
