What Is an HSA

The plain answer

A Health Savings Account, or HSA, is a personal account for eligible medical expenses. To contribute, you must be covered by a qualifying high-deductible health plan and meet the other eligibility rules.

HSAs have three federal tax advantages:

1. Eligible contributions are made before federal income tax or can be deductible.
2. Money in the account can grow without current federal income tax.
3. Withdrawals for qualified medical expenses can be free of federal income tax.

The account belongs to you. It is not a use-it-or-lose-it benefit, and the balance can carry forward from year to year.

How it actually works

For 2026, the HSA contribution limits are:

• Self-only coverage: $4,400
• Family coverage: $8,750
• Additional catch-up contribution at age 55 or older: $1,000

Employer contributions count toward the same annual limit. Your allowed contribution can also be affected by when you become eligible or lose eligibility during the year.

A plan must satisfy federal high-deductible health plan rules to support HSA eligibility. For 2026, the minimum deductible is $1,700 for self-only coverage and $3,400 for family coverage. A plan having a high deductible does not, by itself, prove that it qualifies.

You can use HSA money for qualified expenses now or keep receipts and leave the balance invested for later. Withdrawals for nonqualified expenses are generally taxable, and an additional penalty can apply before age 65.

What this means for you

Confirm eligibility before contributing. Check that your health plan is explicitly HSA-eligible, then review whether other coverage or benefits affect your status. Examples can include a general-purpose health flexible spending account, Medicare enrollment, or being claimed as another person’s tax dependent.

If an HSA fits your health coverage and cash flow, decide how much should remain available for near-term bills and how much can be invested for future expenses. Keep records for qualified medical withdrawals.

An HSA can be valuable, but health coverage comes first. Compare premiums, deductibles, out-of-pocket limits, expected care, and provider access instead of choosing a plan for the HSA alone. Use the order of operations for your money to weigh HSA contributions against emergency savings, debt, and retirement goals.

Common mistakes

• Contributing without confirming that the health plan is HSA-eligible.
• Forgetting that employer contributions use part of the annual limit.
• Treating an HSA like a flexible spending account and rushing to spend the balance.
• Taking a nonqualified withdrawal without accounting for tax and a possible penalty.
• Losing receipts and other records for qualified medical expenses.
• Focusing on tax benefits while ignoring the health plan’s total cost and coverage.
