A Health Savings Account, or HSA, is a special tax-advantaged bank account for medical costs. In 2026 HSAs still offer a triple tax benefit: contributions lower taxable income, money grows tax-free, and withdrawals for qualified medical expenses are tax-free. They’re a simple tool with powerful long-term uses, short-term help for copays and long-term savings for health costs in retirement.

Quick reference

  • Catch-up contribution (age 55+): $1,000 additional per year.
  • Employer contributions count toward the annual limit.
  • Penalty for non-qualified withdrawal before 65: 20% plus income tax. After 65: income tax only (no 20% penalty).
  • Required tax forms: Form 8889 (filed with Form 1040) and Form 1099-SA for distributions.

What is an HSA?

An HSA is a personal savings account you use to pay for eligible medical expenses. Think of it like a dedicated medical wallet that gets special tax treatment. You put money in before taxes through payroll or deduct it on your tax return, the balance can earn interest or be invested, and money you spend on qualified medical costs is tax-free. That’s the basic idea.

HSAs are tied to a qualifying high-deductible health plan, or HDHP. If you don’t have an HSA-eligible HDHP, you can’t open or contribute to an HSA. You can still open an HSA if you’ve left a job and still meet eligibility rules, and balances always stay yours, they roll over year to year with no deadline to spend them.

How it works, step by step

1) Have an HSA-eligible HDHP. Your insurer or employer will say if the plan is HSA-eligible. For 2026 those HDHPs must meet the minimum deductible and maximum out-of-pocket rules listed above.

2) Open an HSA. Employers often offer accounts that tie to payroll.

If not, open one at a bank, credit union, or brokerage that offers HSAs. Look for low monthly fees, clear investment options, and an easy debit card for payments.

3) Contribute. Put money in via payroll pre-tax (best option) or make after-tax contributions and claim the deduction on your Form 1040 using Form 8889. For 2026 you can put in up to $4,400 if you’re single, or $8,750 for family coverage. If you’re 55 or older, you can add a $1,000 catch-up contribution. Employer contributions count toward these limits.

4) Use or invest. Use the HSA debit card, checks, or online bill pay to pay qualified medical costs like doctor visits, prescriptions, dental work, vision care, and hearing aids. Or invest part of the balance in mutual funds or ETFs to grow savings. Many people keep a cash cushion and invest the rest for future needs. HSA money grows tax-free when invested.

5) Report taxes. Keep receipts for expenses. File Form 8889 with your federal tax return to report contributions and distributions. If you take distributions you’ll get Form 1099‑SA. Employer contributions are reported on your W-2 but aren’t taxable income.

Extra rules you should know

The last-month rule: if you’re HSA-eligible on December 1 of a year, you can treat yourself as eligible for the whole year and make the full annual contribution, but you must remain HSA-eligible through the following testing period (usually until Dec. 31 of the next year) or you’ll face taxes and penalties on the excess contributions.

Mastheads

Basically, thing is, medicare and eligibility: once you enroll in Medicare you can no longer contribute to an HSA. But you can use existing HSA funds to pay Medicare Part B, Part D, and Medicare Advantage premiums, and certain other medical costs. Employers can still contribute on your behalf until you enroll in Medicare, but contributions after enrollment aren’t allowed.

State taxes: most states follow federal HSA tax benefits. Still, a few states, notably California and New Jersey, don’t conform to federal HSA rules and may tax contributions or earnings. Check state rules before assuming a full state tax break.

HSAs cut taxes up front and later. That’s rare, only a few personal accounts offer the three-way break (deduction, tax-free growth, tax-free qualified withdrawals).

Over time, that can add up to thousands of dollars in tax savings. For example, if a 35-year-old contributes $4,400 a year and earns modest investment returns, the balance can grow large enough to cover major health costs in retirement.

But HSAs aren’t just about retirement. They help with everyday costs: copays, prescriptions, dental and vision care, things many people pay out-of-pocket. They also protect against big medical shocks: you can build a tax-advantaged emergency fund dedicated to health.

HSAs are flexible. Funds roll over annually.

There’s no required minimum distribution like with IRAs. After age 65, HSA funds can be used for non-medical expenses and treated like traditional IRA withdrawals, taxed as ordinary income but without the 20% penalty.

1) Confirm eligibility: make sure your health plan for 2026 is HSA-eligible. Check the plan documents or ask HR. The plan must meet the deductible and out-of-pocket limits shown above.

2) Compare providers: look at monthly maintenance fees (often $0, $5), investment minimums (common thresholds are $500, $1,000 to start investing), expense reimbursement ease, and available investments like mutual funds or ETFs.

3) Set up contributions: choose payroll pre-tax contributions if your employer offers them. If not, contribute after-tax and claim the deduction. Aim to at least cover predictable annual medical costs, then add investment contributions if you’re building for the long term.

4) Keep records: save receipts and statements. Use an app or folder. For tax time you’ll need Form 8889 and any Form 1099‑SA you received.

5) Plan for Medicare: if you’ll enroll in Medicare soon, stop contributions before the effective date. Use remaining funds for eligible premiums and expenses instead.

Can my employer contribute? Yes. Employer contributions are excluded from income and count toward your annual limit. They’re usually reported on your W-2 but aren’t taxable.

Can I have an HSA and FSA? You can, but only with a limited-purpose FSA (for dental and vision) or a post-deductible FSA; a general-purpose FSA isn't allowed while you're contributing to an HSA.
