A Health Savings Account (HSA) is a tax-advantaged account that eligible people can use to save for qualified medical expenses. It can help an account holder set aside money for current healthcare costs or preserve funds for eligible expenses in the future. Contributions may come from the account holder or an employer, and all contributions count toward one annual federal limit. Unused funds generally remain in the account from year to year, and the account belongs to the individual rather than to an employer. An HSA is not health insurance and does not pay for care simply because a person has an account. Eligibility to contribute depends on federal rules and the person’s coverage during the relevant period. A person can keep and spend an existing HSA balance even after becoming ineligible to make new contributions. The account’s tax benefits depend on following the rules for contributions and withdrawals.

Who Can Contribute to an Hsa?
Eligibility generally requires coverage under a qualifying high-deductible health plan (HDHP) and no disqualifying additional medical coverage. A high deductible by itself does not make a plan HSA-compatible. Federal rules also generally exclude someone enrolled in Medicare or someone who can be claimed as another person’s tax dependent. Eligibility is usually determined month by month, so a change in coverage during the year can affect the amount a person may contribute. A person who is eligible for only part of a year may have a lower contribution limit than someone who qualifies for the full year.
Some other coverage can affect eligibility even if the person has an HDHP. For example, a spouse’s general-purpose health flexible spending account may reimburse the person’s medical expenses and make them ineligible to contribute. Dental and vision coverage generally do not create the same issue. Check the plan terms and the IRS rules rather than relying only on a plan’s name. A plan described informally as high-deductible may not meet the federal requirements for HSA contributions.
Federal rules changed beginning January 1, 2026. Certain individual-market bronze and catastrophic plans are treated as HSA-compatible even when they do not meet the usual HDHP definition. Certain direct primary care arrangements also no longer automatically prevent contributions. The details matter, so review the IRS guidance on 2026 HSA eligibility changes before relying on an exception. Eligibility can depend on the specific plan and arrangement, so a person should verify the rules that apply to their circumstances.
How Are Hsa Contributions Made and Limited?
An eligible person can establish an HSA with a qualified trustee or custodian. Contributions may come from the account holder, an employer or another person. Employer contributions count toward the same annual limit as personal contributions. When contributions are arranged through payroll, the amount is generally taken from pay before it is deposited into the account. The tax treatment can depend on how the contribution is made, so payroll deposits and personal deposits should be tracked separately. Contributions may be made during the year subject to the applicable deadlines and rules.
For 2026, the federal contribution limit is $4,400 for self-only coverage and $8,750 for family coverage. A person who is 55 or older by the end of the year may generally make an additional $1,000 catch-up contribution. The limit may be lower for someone who was eligible for only part of the year, though special rules can apply. The IRS 2026 contribution-limit guidance gives the official annual amounts. The contribution limit applies across all HSAs held by the person rather than separately to each account.
For example, if an eligible person with self-only coverage receives $1,000 from an employer in 2026, the employer amount uses part of the $4,400 limit. The person could generally contribute up to $3,400 more, assuming no other adjustments apply. Contributions above the permitted limit can result in additional tax unless corrected under IRS rules. Anyone changing payroll deductions should account for employer deposits and any contributions made through another job. Checking deposits during the year can help prevent an excess contribution.
What Expenses Can Hsa Funds Cover?
HSA money can generally pay or reimburse qualified medical expenses that have not been paid by insurance or another source. Examples include many medical services and prescription drugs, as well as eligible over-the-counter medicines, dental care and vision care. The account can generally cover qualifying expenses for its owner, spouse and eligible dependents. The IRS explains expense eligibility in Publication 969 on HSAs and other tax-favored health plans. Whether a particular product or service qualifies depends on the applicable tax rules and the reason for the expense.
A person may use an HSA payment card for an eligible bill or pay out of pocket and reimburse themselves later. The expense must have been incurred after the HSA was established. Keep receipts and records that show the service or item, its date and the amount paid. Records are also useful to show that insurance or another benefit did not reimburse the expense. Account holders should retain documentation even if they do not request reimbursement right away.
Health insurance premiums generally are not qualified expenses, although federal rules provide specific exceptions. A nonqualified withdrawal is generally taxable and may also face an additional 20% tax. The additional tax generally does not apply after the account holder turns 65 or becomes disabled, but a nonmedical withdrawal can still be taxable. The account’s tax advantages therefore depend on using the money in accordance with the rules. If a payment is not eligible, the account holder should understand the possible tax consequences before making the withdrawal.
How Is an Hsa Different from an Fsa or Hra?
An HSA belongs to the individual account holder and can retain its balance from year to year. A healthcare limited-purpose FSA is an employer-sponsored arrangement that generally restricts eligible expenses, often to dental and vision care, so it can work alongside an HSA when designed to meet federal rules. A general-purpose HRA is funded by an employer and reimburses expenses according to the plan’s terms. Its availability and treatment when employment ends depend on that arrangement. These differences matter because an HSA balance is individually owned while an FSA or HRA is governed by its plan.
A general-purpose healthcare FSA or HRA may prevent an employee from contributing to an HSA if it can reimburse expenses before the HDHP deductible is met. An ICHRA also requires a compatibility check because its effect can depend on what it reimburses. These arrangements are not interchangeable: they differ in who funds them, how funds are accessed and whether unused amounts stay with the individual. A limited-purpose arrangement may be structured to avoid interfering with HSA eligibility, but the plan terms should be checked.
Workers should identify which account or benefit will pay a particular expense and avoid seeking reimbursement from more than one source. The rules governing an HSA do not automatically apply to an FSA or HRA. Employers and plan administrators can explain the terms of their own arrangements, while federal tax guidance determines whether a person remains eligible to contribute to an HSA. Understanding the funding and reimbursement rules can prevent mistaken assumptions about ownership or tax treatment.
What Happens When Coverage or Employment Changes?
The HSA balance generally stays with its owner after a job change or when HSA contribution eligibility ends. The person may continue using the balance for qualified expenses, but a new health plan can change whether new contributions are allowed. A change in the employer or payroll provider does not itself determine eligibility. The relevant questions are what coverage applies and whether other benefits interfere with HSA eligibility. The account does not automatically close merely because the worker leaves a job or changes assignments.
When changing jobs, keep records of contributions made by each employer and through personal deposits. Contributions from multiple sources count toward one annual limit, not a separate limit for each job or account. Employers report certain HSA contributions on the worker’s year-end tax forms. The account holder generally uses IRS Form 8889 to report contributions and distributions, as explained on the IRS Form 8889 information page. Comparing payroll records with account statements can help identify deposits that need to be reported.
A worker who loses HSA-eligible coverage may generally keep the account and use its existing funds for qualified expenses. However, the worker should not assume that a new employer’s plan permits contributions just because the prior plan did. Coverage and other benefits should be reviewed for the months in which contributions are made. If multiple employers contribute during the year, the worker should monitor the combined amount and discuss any excess contributions with a qualified tax professional or consult IRS guidance.
Why Do Hsas Matter in Contingent Workforce Programs?
For a contingent worker, an HSA can provide account continuity between assignments because the account belongs to the worker. But retaining the account does not guarantee that the worker can keep contributing. Eligibility depends on the worker’s coverage and other circumstances, not simply on whether an assignment is active or which organization’s site they work at. A worker can retain and use an existing balance even during a period when they are not eligible to make new contributions.
Organizations managing a contingent workforce should make clear which employer handles payroll and benefits for each worker. A worker should confirm whether the applicable plan is HSA-compatible and track employer contributions alongside any personal deposits. For programs involving TCWGlobal, the practical question is which benefits arrangement and contribution process applies to the specific worker. Do not assume that a client’s coverage extends to every contingent worker or that an existing HSA makes new contributions permissible.
Clear communication can help workers understand where to direct benefits questions and how employer deposits appear in payroll records. Program administrators can provide information about the benefits arrangement they administer, while the worker remains responsible for understanding personal eligibility and total contributions. These steps are particularly useful when a worker changes assignments or has more than one source of income during the year. The account’s portability is helpful, but it does not replace a review of coverage and contribution rules.
