Quick Answer
Health Savings Accounts (HSAs), health Flexible Spending Arrangements (FSAs), and Health Reimbursement Arrangements (HRAs) differ in eligibility, ownership, funding, and carryover. An HSA belongs to an individual; an FSA is part of an employer plan; an HRA is employer-funded. Account rules do not replace insurance coverage.
How Do Health Accounts Differ from Insurance?
- HSA eligibility depends on federal rules, including qualifying high-deductible coverage.
- FSAs and HRAs have different ownership and reimbursement rules.
- Federal tax treatment and current limits can change.
- A health account is not insurance, even when paired with an insurance plan.
- The medical policy determines covered services and cost sharing. An account can pay or reimburse eligible costs; it cannot create coverage, override an exclusion, or guarantee payment by the insurer.
- A deductible is the amount the insured pays for specified covered care before the plan begins sharing those costs. A charge applied entirely to an unmet deductible remains the insured's responsibility.
- An HSA pays from its available account funds; it is not an insurance benefit or a credit line. If those funds do not cover the bill, the unpaid balance does not automatically become the insurer's responsibility.
Example: A $600 covered bill applies entirely to an unmet deductible. The insured chooses to use their $150 HSA balance.
- The plan pays $0 on this bill.
- The HSA pays the available $150.
- The insured still owes $600 − $150 = $450.
What Should You Compare Before Choosing an Account?
An employee compares an HSA-qualified plan, a health FSA, and an employer HRA. The producer explains who owns and funds each and directs the employee to current employer and Internal Revenue Service (IRS) materials.
Which Coverage Can Support HSA Contributions?
- A high deductible alone does not prove that a plan qualifies for HSA contributions.
- An ordinary HSA-compatible plan has the required minimum deductible and a ceiling on covered annual out-of-pocket costs. Premiums are outside that ceiling.
- Check the plan’s HSA-qualified status, the account type, and other coverage before describing eligibility.
Exam Tip: Gotchas
- Check current IRS limits before quoting an annual contribution amount.
- A high deductible alone does not establish HSA eligibility.
Who Owns Each Account, and What Happens to Unused Funds?
- An HSA is an individually owned account and generally remains with the account holder when employment changes, subject to federal rules.
- Unused HSA amounts generally carry forward from year to year. They do not follow the health FSA's general use-it-or-lose-it rule, and later distributions remain subject to HSA rules.
- An FSA is part of an employer's plan, with elections and available-balance rules set by the plan.
- A plan may permit a carryover, using a limited unused amount in the next plan year, or a grace period, extra time after the plan year to incur eligible expenses. Neither feature is automatic, and a health FSA cannot offer both.
- An HRA is employer-funded and governed by plan terms, so the employee does not own a portable account balance in the same way as an HSA. Only the employer may fund it; employees cannot contribute through salary reductions.
Exam Tip: Gotchas
- An HSA stays with its owner. FSA and HRA balances do not automatically follow the worker to a new employer.
How Are HSA Contributions, Earnings, and Withdrawals Taxed?
Eligible HSA contributions may receive favorable federal tax treatment. Eligibility, contribution limits, and who made the contribution determine the treatment.
A distribution is money withdrawn from the HSA, including amounts used to pay a medical bill. Contribution rules govern money going in; distribution rules govern money coming out.
- Personal contributions: An eligible person can generally deduct qualifying contributions made from their own after-tax funds, within the applicable limit. After-tax funding means the contribution was not excluded from taxable pay through a pretax payroll arrangement. A deduction reduces the income used to calculate federal income tax.
- Employer contributions: Qualifying employer funding is excluded from income, meaning it is kept out of taxable income. Salary reductions through a cafeteria plan, an employer benefit arrangement allowing eligible pretax choices, receive employer-contribution treatment. Do not deduct these excluded amounts again.
- Earnings retained inside an HSA can accumulate without current federal income tax.
- Earnings are not new contributions: Interest or investment growth kept in the account does not use additional contribution room. Count new contributions from all contributors against the applicable limit.
- HSA distributions used for qualified medical expenses, care costs eligible under federal tax rules, can be tax-free when the requirements are met and the costs have not been reimbursed elsewhere.
- A nonqualified HSA distribution can be taxable and may face an additional tax, subject to applicable exceptions.
When Can New Contributions Be Made to an HSA?
Generally, new contribution eligibility requires all of these:
- HSA-compatible coverage.
- No disqualifying other coverage.
- No Medicare enrollment.
- Not being claimable as another taxpayer's dependent.
Other accounts matter: Certain FSAs or HRAs can be disqualifying coverage for new HSA contributions. Check the complete arrangement, not only the medical plan's deductible.
Keeping an existing HSA open does not establish eligibility for new contributions. Timing and the type of coverage also matter:
- Eligibility is generally measured on the first day of each month. A midyear loss of eligibility can reduce the annual contribution limit; special rules can affect the calculation.
- Contributions from the individual, an employer, and other people share the individual's applicable limit. Add the sources before comparing them with the remaining contribution room; do not give each contributor a separate limit.
- Beginning in 2026, qualifying Bronze and Catastrophic plans available as individual coverage through an Exchange, the health-insurance Marketplace, are treated as HSA-compatible even if they do not satisfy the usual deductible and out-of-pocket limits. Other personal eligibility conditions still matter.
- A Bronze group plan does not receive that special treatment merely because it is Bronze. It can still qualify under the ordinary requirements.
- An HSA-compatible plan can cover telehealth or other remote care before the deductible without losing that status.
Which Expenses Can Receive Tax-Free Treatment?
Qualified medical care primarily diagnoses, cures, treats, relieves, or prevents disease, or affects a body function. Ordinary spending for general wellness does not qualify merely because it may improve health.
Tax-free treatment requires all three conditions:
- The expense is a qualified medical expense incurred after the HSA was established.
- Insurance or another source has not reimbursed it.
- The expense has not also been taken as an itemized deduction, an expense deduction separately listed on a tax return.
Which Insurance Premiums Can the Accounts Pay?
- A health FSA cannot reimburse health-insurance premiums or long-term-care expenses. An HRA may reimburse eligible health-insurance premiums and long-term-care coverage when the plan permits.
HSA funds generally cannot pay insurance premiums. Exceptions include:
- Qualified long-term-care insurance, subject to applicable limits.
- Qualifying continuation coverage, such as coverage under the Consolidated Omnibus Budget Reconciliation Act (COBRA).
- Health coverage while receiving federal or state unemployment compensation.
- Medicare or other health coverage when the account owner is age 65 or older. Premiums for Medigap, or Medicare Supplement insurance, are excluded.
Which Costs Qualify, and How Do You Prove Their Use?
- Keep itemized bills, payment records, and reimbursement records establishing those conditions. A debit-card approval or a distribution report does not prove qualified medical use.
- General wellness expenses, such as ordinary health club dues, do not become qualified medical expenses merely because a physician recommends exercise.
What Happens to Nonqualified Withdrawals?
- A nonqualified distribution generally faces income tax plus a 20% additional tax. Reaching age 65 or meeting the disability exception removes the additional tax without making nonmedical spending income-tax-free. Death also does not trigger the additional tax; ordinary income treatment is a separate question.
Example: A $400 nonqualified distribution has no applicable exception:
- Apply the additional-tax rate: $400 × 20% = $80.
- Calculate any ordinary income tax separately. The $80 is the additional tax, not the total tax bill.
