Health Savings Accounts

What an HSA is

A Health Savings Account is a tax-favored account an eligible individual can use to pay qualified medical expenses. It is paired with qualifying high-deductible health plan coverage, but the insurance plan and the savings account are distinct. The plan covers health costs under its terms; the HSA holds money owned by the individual. An employer may contribute, but the account remains portable when employment changes. Do not assume that every person with a high deductible qualifies or that the employer owns the deposited balance.

The exam-level concept is the interaction among eligibility, contributions, investment growth and distributions. Contributions may be deductible or excluded from income depending on who makes them and how. Earnings can grow tax-advantaged, and distributions used for qualified medical expenses may be tax-free. A distribution for another purpose can have different tax treatment. These features can be valuable, but they do not turn an HSA into a general-purpose retirement account while the individual is below the relevant age and no exception applies.

Who may contribute

Eligibility generally requires the person to be covered by an HSA-qualified high-deductible health plan and not have disqualifying additional coverage, be enrolled in Medicare, or be claimable as another person’s dependent. Exact eligibility is determined month by month and can be affected by coverage changes. A spouse’s general-purpose health FSA can matter even if the HSA owner does not use it. A limited-purpose or post-deductible arrangement may be treated differently. Check the current IRS publication and plan documents rather than relying on the word “high deductible” in a marketing summary.

For 2026, the IRS lists a contribution limit of $4,400 for self-only coverage and $8,750 for family coverage. Eligible individuals age 55 or older may also qualify for a $1,000 catch-up contribution, subject to the statutory conditions. An individual eligible for only part of the year may have a prorated limit, with special rules such as the last-month rule and a testing period. The family limit is not a per-covered-person allowance for one account owner. Employer and employee contributions count toward the applicable aggregate limit.

Consider an employee with family HDHP coverage for six months and self-only coverage for six months. It is incorrect to apply the full family limit and then add the full self-only limit. The contribution ceiling depends on the months of eligibility and coverage type, along with any rule that applies to the facts. Contributions from an employer also count. The right calculation begins with a calendar, not with the annual maximum printed in a table.

A 2026 coverage change

Federal law changed HSA eligibility for certain insurance arrangements beginning in 2026, including specified bronze and catastrophic plans offered through an Exchange. Separate amendments affected telehealth and other remote care rules. That does not mean every plan carrying a bronze or catastrophic label has identical terms or automatically satisfies all HSA conditions. Confirm the plan’s year, source and precise legal category. Do not transfer a 2026 rule to an earlier tax year or assume a plan qualifies based only on its deductible.

For example, a client may say, “My new marketplace policy is bronze, so I can contribute.” The adviser should check whether it is an Exchange plan within the amended category and whether other disqualifying coverage applies. The client’s Medicare enrollment, dependent status, health FSA access and months covered still matter. The conclusion is person-specific. A change in federal law expands eligibility for some people; it does not eliminate the other eligibility tests.

Contributions and account ownership

An individual can receive contributions from an employer, the individual, or another person, subject to the annual limit and eligibility. Employer amounts reduce the room available for additional contributions. Rollovers generally are treated differently from annual contributions, but must meet applicable requirements. The account is owned by the individual, so a job change does not by itself convert the balance into an employer asset. The owner may keep the account, subject to the custodian’s terms and fees.

A contribution is not a payment of a medical bill. It moves money into the account and may have a tax result depending on its source. A distribution removes money to pay a cost or for another purpose. A family might make a contribution in one year and use the money later. Records should show contribution date and source, distribution amount, medical expense and whether it was reimbursed or deducted elsewhere. Confusing the two sides can lead to an incorrect tax explanation.

Qualified medical distributions

An HSA distribution is tax-free when it pays a qualified medical expense for the account holder, spouse, or qualifying dependent under the rules. The expense generally must be incurred after the HSA is established and cannot already have been reimbursed by insurance, another account, or a tax deduction. A medical expense qualifies based on tax rules, not because a vendor accepts an HSA card. Keep receipts and explanation-of-benefits records even if the custodian approves the debit card transaction.

Suppose a person pays a $600 eligible dental bill from a checking account, keeps the receipt, and later reimburses themselves from the HSA. The later reimbursement may be permitted if the expense was incurred after the HSA existed, was qualified, and was not reimbursed or deducted elsewhere. The person should preserve the original bill and payment proof. A swipe at a merchant is not a substitute for the tax records. The owner may need documentation years later if the withdrawal is questioned.

Insurance premiums are generally not qualified medical expenses for HSA distribution purposes, though statutory exceptions exist for specified circumstances such as certain continuation coverage or Medicare-related premiums. Avoid saying “premiums never qualify” or “all premiums qualify.” Identify the premium type, the individual’s status and the applicable exception. An ordinary health-insurance premium should not be assumed eligible merely because it buys medical coverage.

Nonmedical use and later-life treatment

A distribution not used for a qualified medical expense is generally included in gross income and may face an additional 20% tax. The additional tax does not apply in certain circumstances, including after the account holder reaches age 65, becomes disabled, or dies; income-tax treatment may still apply. This means an HSA can function differently later in life, but it is not accurate to say every post-65 withdrawal is tax-free. Only qualified medical distributions retain the favorable tax-free treatment.

A client who uses the HSA debit card for a vacation should not assume that the custodian’s payment makes it qualified. If the expense is not eligible, the owner must report the distribution under the tax rules and could owe the additional tax depending on age and circumstance. A separate check or card does not change the substance. The account holder is responsible for substantiating use even when the custodian does not review receipts at the moment of withdrawal.

Compare HSA with FSA and HRA

An HSA is individually owned and can remain with the person across jobs, subject to custodian fees and rules. A health flexible spending arrangement is generally employer-sponsored and has different contribution and carryover rules. A health reimbursement arrangement is funded by an employer and is governed by its plan terms. These are not interchangeable simply because all can pay some medical costs. The type of account affects eligibility to contribute, who owns the balance, how unused amounts are treated and what documentation applies.

A general-purpose health FSA or HRA may prevent HSA contributions because it provides disqualifying coverage. Some limited-purpose arrangements, such as dental or vision coverage, or post-deductible coverage, may be compatible under applicable rules. The employee should inspect the plan year and actual covered expenses. An employer’s benefits summary can use terms loosely, so the plan document is the better source for what coverage exists.

Worked case: job change and mixed eligibility

Devon has an HSA from a previous employer and starts a new job midyear. The new employer offers family coverage, but Devon’s spouse has a general-purpose FSA. Devon should check when the new coverage begins, whether the spouse’s FSA can reimburse Devon’s costs, whether Devon is eligible in each month, and how much the former and new employer contributed. If the FSA is disqualifying, Devon may be ineligible to contribute for affected months even though the HDHP itself meets the technical plan requirements. The old HSA balance remains Devon’s asset; contribution eligibility is a separate question.

The employer deposits $1,000 into the new account. Devon cannot treat that amount as separate from the annual limit and contribute the full published maximum on top. The aggregate calculation includes employer contributions. Devon should also confirm whether the spouse’s plan covers only limited dental or vision costs or broader medical expenses. One fact about the FSA can change the contribution analysis, while the existing account balance remains available for qualified distributions.

Worked case: delayed reimbursement

Priya keeps receipts for eligible medical expenses paid from her bank account after opening an HSA. Years later, she wants to reimburse herself. She should confirm the expenses were incurred after the account was established, remain unreimbursed, were not claimed as itemized deductions, and meet the qualified medical definition. She should retain proof of payment and the HSA’s opening date. If a receipt predates the account or was already covered by insurance, it cannot simply be relabeled as an HSA expense.

This example shows why good records create flexibility. The account can hold assets for future medical needs, but the owner must preserve enough evidence to support a later distribution. A ledger can include date, provider, patient, expense category, gross charge, insurance payment, amount paid personally, and reimbursement status. If a family member paid the bill or the expense belongs to someone else, verify the relationship and tax definition before reimbursement.

Practical review and common traps

Before recommending a contribution, check eligibility by month, coverage type, other coverage, Medicare status, dependency status, age catch-up, employer contributions and the current-year limit. Before a withdrawal, check expense date, qualified status, patient, prior reimbursement, deduction treatment, and records. The two checklists differ because eligibility to contribute and eligibility to spend are separate questions. Passing one test does not establish the other.

Common errors include treating the annual limit as per account, overlooking employer deposits, assuming every HDHP qualifies, and confusing account ownership with employer sponsorship. Others assume every medical-sounding purchase qualifies, that an HSA card validates the expense, or that age 65 makes all withdrawals tax-free. A precise answer names the tax year and separates eligibility, contribution room, distribution use and additional-tax exceptions.
