Health Savings Accounts remain one of the most valuable tax-advantaged savings tools available, and several changes beginning in 2026 expand who may qualify.

At the same time, the basic HSA eligibility rules have not disappeared.

Understanding both sides is important before making contributions.

2026 HSA Contribution Limits

For 2026, the annual HSA contribution limits are:

  • $4,400 for self-only high-deductible health plan coverage
  • $8,750 for family coverage

Eligible individuals age 55 or older may make an additional $1,000 catch-up contribution.

For married couples, the catch-up contribution belongs to each individual spouse. If both spouses are at least age 55 and eligible, each spouse must have their own HSA in order to make their respective $1,000 catch-up contribution.

HSA Eligibility Is Determined Month by Month

One of the most important HSA rules has not changed.

Generally, a taxpayer must be HSA-eligible on the first day of the month for that month to count toward the annual contribution limit.

For example, assume qualifying HSA-compatible coverage begins on April 8. April generally would not count as an eligible month because coverage was not in place on April 1.

May would ordinarily be the first eligible month, assuming all other requirements are met.

Changes in insurance coverage during the year can therefore affect the allowable annual contribution.

Certain Bronze and Catastrophic Plans Now Qualify

Beginning in 2026, certain bronze and catastrophic plans offered in the individual health insurance market are treated as high-deductible health plans for HSA purposes.

This is significant because some of these plans would not have met the traditional HSA-compatible deductible or out-of-pocket requirements.

The new law can therefore create HSA eligibility for individuals who previously could not contribute.

However, the special rule does not eliminate the other HSA requirements.

A taxpayer may still be ineligible because of:

  • Medicare enrollment
  • A spouse’s general-purpose health FSA
  • Certain health reimbursement arrangements
  • Other non-HDHP medical coverage
  • Being eligible to be claimed as another taxpayer’s dependent

The insurance plan itself is only one part of the eligibility analysis.

Direct Primary Care Can Now Be HSA-Compatible

Direct primary care arrangements have become increasingly popular.

Under these arrangements, a patient generally pays a fixed monthly membership fee directly to a medical practice for access to primary care services.

Beginning in 2026, certain qualifying direct primary care service arrangements do not disqualify an otherwise eligible taxpayer from making HSA contributions.

For 2026, total monthly fees generally cannot exceed:

  • $150 for an arrangement covering one individual
  • $300 for an arrangement covering more than one individual

The arrangement must also meet specific requirements regarding the services offered.

For example, assume an individual pays $140 per month for a qualifying direct primary care arrangement that provides only eligible primary care services.

If the taxpayer also has qualifying HSA-compatible insurance and no other disqualifying coverage, the arrangement may be compatible with HSA contributions.

If the monthly fee exceeds the applicable limit, the analysis changes. The expense may still qualify for reimbursement from an HSA, while the arrangement itself may make the taxpayer ineligible to contribute for those months.

Contribution eligibility and reimbursement eligibility are separate questions.

Telehealth Relief Is Permanent

The 2026 rules also permanently preserve favorable treatment for qualifying telehealth and other remote-care services.

An otherwise qualifying high-deductible health plan may provide certain telehealth services before the deductible is satisfied without causing the plan to lose HSA-compatible status.

This relief applies to plan years beginning after December 31, 2024.

Watch Medicare Enrollment Carefully

HSA contributions must stop beginning with months in which the taxpayer is enrolled in Medicare.

This becomes especially important for individuals who continue working after age 65 and delay Medicare enrollment.

When Medicare Part A coverage is later made retroactive, HSA contributions made for those retroactive months can become excess contributions.

The HSA itself does not have to be closed when Medicare begins.

Existing HSA funds may still be used tax-free for qualifying medical expenses. The restriction applies to new contributions.

An Opportunity for Some Adult Children

One lesser-known HSA rule can create an interesting planning opportunity.

Assume a 23-year-old remains covered under a parent’s family high-deductible health plan.

If the adult child:

  • Cannot be claimed as the parent’s tax dependent
  • Has no other disqualifying health coverage
  • Is not enrolled in Medicare
  • Is otherwise HSA eligible

the child may establish their own HSA and may potentially qualify for the full family HSA contribution limit.

The parent’s HSA and the adult child’s HSA are separate accounts with separate contribution limits.

However, because the adult child is not the parent’s tax dependent, the parents generally should not use their own HSA to reimburse that child’s medical expenses.

Keep the Records

HSA distributions are tax-free only when used for qualified medical expenses.

Taxpayers should retain:

  • Medical receipts
  • Explanation-of-benefits statements
  • Pharmacy records
  • Records showing expenses were not reimbursed by insurance or another plan
  • Documentation of HSA eligibility and coverage

Unlike an FSA, an HSA does not require reimbursement in the same year the medical expense is paid.

A taxpayer may pay an expense personally, allow the HSA to continue growing, and reimburse themselves from the HSA years later, provided they can document that the expense was incurred after the HSA was established and was never previously reimbursed.

The Bottom Line

The 2026 changes expand HSA opportunities, particularly for taxpayers purchasing individual-market bronze or catastrophic coverage or participating in qualifying direct primary care arrangements.

But HSA eligibility remains highly dependent on the taxpayer’s specific insurance coverage and circumstances.

Before maximizing an HSA contribution, make sure the taxpayer was actually eligible for each month included in the calculation.
