Email Guidance - 2025 HSA Contribution Limit for a Married Couple

Q-1. We have a question about contribution limits for 2025 from a customer. They will be covered by a family plan for all of 2025 so they know the limit is $9,550.00. HSA Owner is 62, spouse is 64. However, in November 2025 the husband is going to turn 65 and go on Medicare so can no longer contribute to the HSA. So, what is the best way to figure out how much they can contribute prior to that? Take $9,550.00 divide by 12 and then multiply by 10 months since the husband can no longer contribute for November and December? Or Is there an easier solution? They want to maximize their contributions the best they can.

A-1. Excellent question. The maximum HSA contribution for 2025 when there is family HDHP coverage is $8,550 if both spouses are less than age 55. For 2024 this limit is $8,300. A married couple may split this amount any way they agree upon. It could all go into his HSA or it could all go into her HSA.

This maximum limit is not decreased because one of the spouses is ineligible for a certain number of months.

Each spouse must make the $1,000 catch-up to her or his own HSA This $1,000 is reduced pro rata when a spouse is not eligible for all 12 months.

The maximum contribution amount for 2025 is $10,550 if both spouses who are age 55 or older are eligible for all 12 months. But he is not. He will only be eligible for 10 months.

Because he is ineligible for 2 months, they may agree to have her HSA contribution be $9,550 ($8,550 +$1,000) and his HSA contribution would be $833.33 ($1,000 x 10/12). Their maximum contribution is $10,383.33.

They should confirm with their tax adviser.
