Updated August 3, 2026. Quick answer: if you and your spouse are both 55 or older, you can each make a catch-up contribution — but each of you must have your own HSA. Both catch-ups cannot go into one account. A couple with a single family HSA loses one catch-up every year until they open the second account.
The rule
In the case of an individual who has attained age 55 before the close of the taxable year, the applicable limitation under subparagraphs (A) and (B) of paragraph (2) shall be increased by the additional contribution amount. … [Sec. 223(b)(5)(B)] The limitation under paragraph (1) (after the application of subparagraph (A) and without regard to any additional contribution amount under paragraph (3))— (i) shall be reduced by the aggregate amount paid to Archer MSAs of such spouses for the taxable year, and (ii) after such reduction, shall be divided equally between them unless they agree on a different division. [Pub. 969:] If both spouses are 55 or older and not enrolled in Medicare,…

Two separate provisions combine into the trap. The catch-up is an individual increase to the contributor’s own limit, and the statute expressly computes the family limit without regard to the catch-up amount before dividing it between spouses. And the IRS has answered the underlying question directly: there is no such thing as a joint HSA. Only one person can be the account beneficiary.
Why it catches people
Because a family high-deductible plan naturally produces one family HSA, usually opened through one spouse’s employer. The family contribution limit genuinely is shared and divisible between spouses — so it feels as though everything about the couple’s HSA is joint. The catch-up is the exception, and it is the one part that cannot be pooled.
The loss is quiet and recurring: one catch-up amount, every year, for as long as both spouses are eligible and only one account exists.
The fix
- Open a second HSA in the other spouse’s name. They can hold one as long as they are an eligible individual — covered by a qualifying high-deductible plan and not enrolled in Medicare.
- Put only that spouse’s catch-up in it if you prefer to keep the main balance in one place. It does not need to hold the family contribution.
- Check Medicare status for each spouse separately. Eligibility is individual, and enrolling in Medicare ends it — with a lookback that catches people at exactly this age.
- Do not over-contribute while fixing it. Two accounts do not mean two family limits. Excess contributions carry a repeating excise.
