What an HSA is, fast

An HSA is a personal savings account that combines tax savings with flexibility for medical costs. Contributions go in pre-tax if made through payroll, or you can deduct post-tax contributions on your 1040. Earnings grow tax-free. Withdrawals for qualified medical expenses are tax-free. You're allowed to invest HSA dollars once the account reaches a custodian's investment minimum, and unused funds roll over from year to year, no "use-it-or-lose-it."

HSAs belong to the individual, not the employer. So they travel with you when you change jobs or retire. But keep this in mind: you can't contribute once you're enrolled in Medicare Part A or B, though you can still use the money in the account to pay certain Medicare premiums and qualified medical costs.

Prerequisites: who’s eligible

To open and contribute to an HSA in 2026 you must meet these conditions:

Mastheads
  1. Be covered by an HSA-eligible High Deductible Health Plan (HDHP). For 2026 that means a minimum deductible of $1,800 for self-only coverage or $3,600 for family coverage. Maximum out-of-pocket limits are $8,400 for self-only and $16,800 for family plans.
  2. Not be enrolled in Medicare (Part A or B). Once Medicare enrollment begins, contributions stop. You can still use funds already in the account.
  3. Not have other disqualifying health coverage, specifically, no general-purpose health FSA or non-HDHP insurance that pays before the deductible. Limited-purpose FSAs (vision, dental) are allowed alongside an HSA.
  4. Not be claimed as a dependent on someone else's tax return for the year.

Check your Summary of Benefits and Coverage (SBC) or ask HR whether the employer plan is HSA-eligible. Official government guidance is at IRS.gov and Healthcare.gov.

Step-by-step: open an HSA and start using it

Follow these numbered steps to open an HSA and make the most of it.

  1. Confirm HDHP eligibility. Look at your plan documents or call the carrier. The plan must meet the 2026 deductible and out-of-pocket thresholds above. If you're part of an employer plan, HR can confirm HSA-eligibility and whether pre-tax payroll deductions are offered.
  2. Choose a custodian. Compare banks, brokerage custodians, and dedicated HSA administrators. Popular custodians in 2026 include Fidelity (https://www.fidelity.com/health-savings-account), HSA Bank (https://www.hsabank.com), HealthEquity (https://www.healthequity.com), Lively (https://livelyme.com), Optum Bank (https://www.optumbank.com) and major banks like Bank of America (search "Bank of America HSA"). Check fees, investment choices, trading costs, and whether there's a brokerage window.
  3. Open the account online or via employer. Typical fields: Social Security number, date of birth, address, driver's license, employer name (if applicable), HSA-eligible plan name, and beneficiary designation. Employer-sponsored HSAs often have an administrator. If your employer offers pre-tax payroll contributions, ask HR for the administrator's enrollment link.
  4. Fund the account. Allow payroll pre-tax contributions if available, it's the simplest tax benefit. Or make post-tax contributions and claim the deduction on Form 1040 (Schedule 1). For 2026, limits are $4,600 (self) and $9,200 (family). If you're 55 or older by Dec. 31, 2026, add a $1,000 catch-up contribution. Contributions for 2026 can be made until the 2027 tax filing deadline (usually April 15, 2027).
  5. Watch contribution rules and corrections. Excess contributions are subject to a 6% excise tax per year until corrected. You can withdraw excess contributions plus earnings to avoid the penalty. Use Form 5329 and Form 8889 when filing taxes to report contributions and distributions.
  6. Invest when ready. Many custodians let you hold cash and invest once the balance hits a minimum, often $500 to $2,000 depending on the provider. Investment options commonly include low-cost index mutual funds, ETFs, and target-date funds. Keep an eye on expense ratios, index funds can be as low as 0.01% while some actively managed funds run 0.50% or more.
  7. Pay qualified medical expenses. Use your HSA debit card or reimburse yourself later. Qualified expenses include prescription drugs, most dental and vision care, co-pays, deductibles, and certain long-term care costs, see IRS Publication 502 for the exhaustive list. Keep receipts. If you use HSA funds for non-qualified expenses before age 65, you'll owe income tax plus a 20% penalty. After 65, non-qualified withdrawals are taxed as ordinary income but incur no penalty.
  8. Recordkeeping and taxes. Expect Form 1099-SA for distributions and Form 5498-SA that reports contributions. Use Form 8889 with your Form 1040 to report HSA activity. If you have an employer-sponsored HSA, confirm how employer contributions are reported, employer contributions reduce your personal contribution limit dollar-for-dollar.
  9. Plan for life changes. You can roll over or transfer an HSA trustee-to-trustee at any time without tax. A one-time rollover from an IRA to an HSA, called a Qualified HSA Funding Distribution, is allowed once per lifetime and counts toward that year's contribution limit.

Tips for using an HSA effectively

Save receipts. Even if you pay out-of-pocket, save documentation, you can reimburse yourself tax-free years later for past qualifying expenses.

Think long term. Many people treat an HSA as a retirement health fund.

If you can cover current medical bills with cash, let the HSA invest and grow tax-free for future, likely higher health costs.

Here's the thing, compare fees closely. Monthly maintenance fees of $2, $5, per-trade fees for investments, and annual custodial fees up to $50 are common. If you plan to invest, ask about a brokerage window and minimum balance to avoid fees.

Use tax tools. Software and tax preparers recognize Forms 1099-SA, 5498-SA and 8889. Track employer versus personal contributions so you don't over-contribute.

  • Mixing up enrollment dates. Don't contribute after you enroll in Medicare. Contributions stop the month Medicare coverage begins.
  • Over-contributing. The 6% excise tax adds up. Make timely corrections before the tax filing deadline.
  • Not keeping receipts. IRS audits happen. Receipts support tax-free withdrawals and reimbursements.
  • Using funds for non-qualified expenses before 65. That triggers income tax plus a 20% penalty. After 65, non-qualified withdrawals are taxed but penalty-free.
  • Assuming all custodians are the same. Some custodians offer robust investment choices with low fees (Fidelity, Vanguard-type offerings); others focus on debit-card convenience and basic savings. Shop around.
  • Forgetting coordination with FSAs. Having a general-purpose FSA disqualifies you from HSA contributions. A limited-purpose FSA for dental and vision can be HSA-compatible.
