EMPLOYEE BENEFITS GUIDE · REVIEWED OCTOBER 22, 2026
HSA eligibility rules determine whether you can add money to a health savings account. Having an HSA already open does not, by itself, establish that you can contribute this month. Before setting a payroll deduction, review your medical coverage, other benefits and any changes affecting your eligibility.
This guide focuses on the checks to make when your circumstances change. For the account basics, read what an HSA is and how it works. For the current annual figures, use ESI’s HSA contribution limits guide.
HSA Eligibility Rules: Start With Your Coverage
IRS Publication 969 explains the general eligibility conditions: qualifying health coverage, no disqualifying other coverage, no Medicare enrollment and no eligibility to be claimed as someone else’s tax dependent. Eligibility is generally assessed on the first day of each month.
Ask the benefits team to identify the exact medical option you selected and whether it is HSA-compatible. A plan’s deductible amount or marketing label alone does not answer every eligibility question. Keep the written answer with your election record.
Check Other Coverage Before You Contribute
A general-purpose health FSA or HRA can affect eligibility. A spouse’s health FSA can also matter if it can reimburse your expenses. Certain limited-purpose or post-deductible arrangements can work differently. Review the actual arrangement rather than assuming that every spending account has the same effect.
When comparing an HSA and an FSA, list every account that may reimburse your care. Ask the account administrator about any carryover or grace period if you plan to move into HSA-compatible coverage. A balance from the prior plan year can raise a question that is easy to miss during enrollment.
Know Which Recent Rule Changes Apply
Pre-Deductible Telehealth
The IRS guidance announcement on expanded HSA access describes several changes now relevant when reviewing coverage for 2027. It explains permanent relief for telehealth and remote care before an HDHP deductible, effective for plan years beginning on or after January 1, 2025.
Bronze and Catastrophic Individual Coverage
Beginning January 1, 2026, qualifying bronze and catastrophic individual-market coverage receives special HSA treatment. This does not automatically make an employer group bronze plan HSA-compatible. Notice 2026-05, Questions 4–8, explains the individual-market conditions, including off-Exchange coverage and the distinction for SHOP group coverage.
Qualifying Direct Primary Care Arrangements
Certain direct primary care service arrangements no longer prevent an otherwise eligible person from contributing, beginning January 1, 2026. The arrangement must satisfy the legal definition and fee conditions. A membership label alone is insufficient. For 2027, Revenue Procedure 2026-24 confirms monthly aggregate fee thresholds of $150, or $300 when an arrangement covers more than one person.
Ask the provider and benefits team to confirm the arrangement’s terms before assuming that an ordinary concierge or subscription service qualifies. These provisions took effect before 2027; they should not be described as newly enacted 2027 rules.
Bring the exact plan or arrangement name to your benefits team or tax adviser. Ask which provision applies and whether anything else in your household’s coverage prevents contributions. Avoid changing payroll elections solely because a headline says HSA access expanded.
Match Contributions to Your Own Allowance
Employee and employer contributions generally share the applicable annual limit. Contributions to multiple HSAs do not create separate annual allowances. Part-year eligibility, coverage changes and the last-month rule can affect the amount you may contribute. The last-month rule has a testing period; it is not a simple exemption from eligibility requirements.
Use a contribution worksheet with separate lines for employer funding, payroll deductions and deposits made outside payroll. Ask for help calculating your personal allowance when eligibility changes during the year. The maximum in an annual table may not be your own permitted amount.
IRS Revenue Procedure 2026-24 confirms the 2027 HSA inflation-adjusted amounts. Use the linked limits guide for the dated comparison. Keep this rules checklist alongside the table so the annual maximum is not mistaken for an automatic contribution entitlement.
Pause and Review When Coverage Changes
Tell the benefits team when you change medical options, gain other coverage or approach Medicare enrollment. Ask which month is affected and whether your payroll contribution needs an adjustment. If the change happens outside annual enrollment, confirm both the insurance effective date and the deduction date.
If you suspect an excess contribution, contact the HSA custodian and a tax adviser promptly about the correction process. Do not assume that an ordinary account withdrawal is the same as a properly processed correction.

Frequently Asked Questions
Can I Keep My HSA If I Stop Being Eligible to Contribute?
Yes. Contribution eligibility and ownership of an existing account are separate questions. IRS Publication 969 explains that you can generally retain the account and use available funds for qualified medical expenses. Review eligibility before adding new money.
Does an Employer Deposit Increase My Annual Limit?
No. Count employer funding together with your own contributions when checking the applicable allowance. Ask for a calculation when you change coverage or eligibility during the year.
Are the Expanded HSA Rules New for 2027?
The telehealth provision applies to plan years beginning in 2025; the individual bronze/catastrophic and qualifying direct primary care provisions apply beginning in 2026. Review those existing changes alongside the separate official 2027 annual limits.
