Health Savings Account (HSA) Explained: Benefits, Rules and 2026 Contribution Limits
Healthcare expenses can take a significant portion of a household budget in the United States. One tool that can help eligible Americans manage those costs while receiving tax advantages is a Health Savings Account, or HSA.
An HSA allows eligible individuals to set aside money for qualified medical expenses. Unlike a regular savings account, it can provide important federal tax benefits.
Here is how an HSA works and what you should know about the 2026 contribution limits.
What Is a Health Savings Account?
A Health Savings Account is a tax-advantaged account designed to help eligible individuals pay qualified healthcare expenses.
To contribute to an HSA, you generally need to be covered by an HSA-eligible High Deductible Health Plan, or HDHP, and meet other IRS eligibility requirements.
The account belongs to you, not your employer.
This means the money generally remains yours even if you change jobs or health insurance plans.
Who Is Eligible for an HSA?
Generally, to contribute to an HSA, you must:
- Have qualifying HDHP coverage
- Not have certain other disqualifying health coverage
- Not be enrolled in Medicare
- Not be claimed as someone else’s dependent for tax purposes
Other eligibility rules can apply, particularly if you have additional health coverage or a Flexible Spending Account.
2026 HSA Contribution Limits:
For 2026, the IRS HSA contribution limits are:
- Self-only coverage: $4,400
- Family coverage: $8,750
For 2026, an HSA-qualified high-deductible health plan generally must have a deductible of at least $1,700 for self-only coverage or $3,400 for family coverage. Applicable out-of-pocket maximums are $8,500 and $17,000 respectively.
People age 55 or older who meet the requirements may generally make an additional $1,000 catch-up contribution.
Remember that employer contributions generally count toward your annual HSA contribution limit.
What Are the Tax Benefits of an HSA?
One reason HSAs are popular is their tax treatment.
- Contributions May Reduce Taxable Income: Eligible contributions can generally be deductible for federal income-tax purposes. If contributions are made through an eligible employer arrangement, they may receive different payroll-tax treatment as well.
- Money Can Grow Tax-Free: Interest and investment earnings within the HSA generally are not currently taxed for federal income-tax purposes while remaining in the account.
- Qualified Medical Withdrawals Can Be Tax-Free: Distributions used for qualified medical expenses can generally be excluded from federal taxable income.
These features make an HSA different from an ordinary savings account.
What Can HSA Money Be Used For?
HSA funds may generally be used for qualified medical expenses for you, your spouse, and eligible dependents.
Examples may include:
- Doctor visits
- Prescription medications
- Dental treatment
- Vision care
- Certain medical equipment
- Deductibles
- Copayments
- Other IRS-qualified medical expenses
Not every health-related expense qualifies, so it is important to check current IRS rules.
Does HSA Money Expire?
No.
This is a major difference between an HSA and some Flexible Spending Accounts. Unused HSA money generally rolls over from one year to the next.
If you contribute $3,000 and spend only $1,000, the remaining balance can stay in your account.
There is generally no requirement to spend the money by the end of the year.
Can You Invest HSA Money?
Some HSA providers allow account holders to invest part of their balance in investments such as mutual funds after meeting the provider’s requirements.
This can make an HSA useful for both current healthcare expenses and long-term healthcare planning.
However, investing HSA funds introduces market risk.
Money that may be needed soon for medical bills may be better kept in a more liquid option.
What Happens to Your HSA When You Change Jobs?
Your HSA belongs to you.
Changing employers does not generally cause you to lose your existing HSA balance. You may continue using existing funds for qualified medical expenses even if your next employer uses a different HSA provider.
However, your ability to make new contributions depends on whether you continue meeting HSA eligibility requirements.
What Happens After Age 65?
HSA funds can still be used for qualified medical expenses after age 65. Withdrawals for qualified expenses can generally remain tax-free.
If you withdraw money for nonmedical purposes after reaching age 65, the withdrawal generally becomes taxable income, but the additional HSA tax penalty that normally applies to many nonqualified withdrawals before age 65 generally does not apply.
This gives HSAs additional flexibility in retirement.
HSA vs FSA: What Is the Difference?
An HSA and Flexible Spending Account are not the same. An HSA is individually owned and its balance generally rolls over from year to year.
An FSA is usually employer-sponsored and can have different rules regarding unused funds, eligibility, and portability.
You also generally cannot contribute to an HSA while covered by a general-purpose healthcare FSA, although certain limited-purpose arrangements may be compatible.
Common HSA Mistakes to Avoid:
Some common mistakes include:
- Contributing when you are no longer eligible
- Exceeding the annual contribution limit
- Using HSA money for nonqualified expenses without understanding the tax consequences
- Failing to keep receipts and documentation
- Forgetting that employer contributions count toward the annual limit
- Investing money that may soon be needed for medical expenses
Keeping accurate records is important.
