Hello,

I learned much from the forum, and had received help earlier from Opus17 and BillM223 in March.
So, I am continuing to work at age 70, ready to join a HDHP plan at the upcoming open enrollment in Dec 2025, to also cover my wife, and my college grad, dependent on the same tax return, until she moves out.

1. Should I sign up for such HPDP family plan, so that my wife can get her own HSA where her contributions are tax deductible
2. Would I take care of my health expenses via my typical annual premium and savings, but cannot use any money from the HSA
3. Would my wife's HSA annual contributions be limited to a single, or a family maximum?
4. Would my daughter be allowed to use such HSA savings for health/ medical expenses?
Thank you!

Yes, if you have a family plan she can have her own HSA. I assume that she is not on Medicare and is otherwise eligible.

2. Would I take care of my health expenses via my typical annual premium and savings, but cannot use any money from the HSA.

While you can’t make any contributions since you are on Medicare, you can use your existing HSA if you have one or you can use withdrawals from hers to pay your medical expenses and even your Medicare premiums.
3. Would my wife's HSA annual contributions be limited to a single, or a family maximum?

Since you can’t contribute to an HSA she can contribute to her HSA the maximum of the family plan allowed by law.
4. Would my daughter be allowed to use such HSA savings for health/ medical expenses?

As a dependent, HSA funds from your (if you have one) or your wife’s HSA can be used for your daughter’s medical expenses.

@W16VA While others are certain to answer your questions, I have one....given you are over 65, did you sign up for Medicare Part A, which is normally free? If yes, you are not eligible to contribute to an HSA. Just wanted to get that one out of the way as it is often overlooked.

Thank you for your very clear reply!

Indeed I did not know to get my own HSA earlier, and now being under part A took away that option.

I just try to find out the last chance to get my wife her HSA, since her work has Aetna but not with any HDHP option.

1. I will proceed with a family HDHP plan which has Inspira to manage HSA. I will find out whether they would handle my wife's HSA, since I can't have my own. How would the contributions take place, monthly or as a lump sum, up to the limits within each year?

2. I plan to stay on such HDHP plan. working for another year or two, would her HSA's contributions be prorated to those months I am still covered by that plan? If I happen to retire early during a year, I assume the remaining months can not allow any further deductible contributions.

Finally, I hope such HSA money can be used later while we both no longer can be in any HDHP.

Thank you!

Your wife can't contribute using your payroll deductions under your employer sponsored plan. She has to contribute using her own money. She will have to open her own HSA account at any bank that offers them; there are many–Inspira might even offer private accounts in addition to work sponsored accounts. If not, HSAs are offered by other banks. Make sure to ask about transaction fees and monthly or annual maintenance fees. Those fees are probably covered by the employer if you have an employer account but you (or she) will pay them if you have a private account.

She can contribute at any time in any manner she chooses--monthly, weekly, lump sum, whatever--as long as her total annual contribution is not more than the maximum for that year.

2. I plan to stay on such HDHP plan. working for another year or two, would her HSA's contributions be prorated to those months I am still covered by that plan? If I happen to retire early during a year, I assume the remaining months can not allow any further deductible contributions.

In any year where she is not covered by an HDHP for the entire year, her contribution limit is pro-rated on a monthly basis, with eligibility determined by her insurance coverage as of the first day of the month. In other words, if you terminate your insurance on July 15, she would be eligible for 7 months and her contribution limit would be 7/12th of whatever the maximum was for that year.

Finally, I hope such HSA money can be used later while we both no longer can be in any HDHP.

Your HSA funds belong to you forever. They can always be spent tax-free for qualified medical expenses for the account owner, their spouse, and their tax dependents. The rules for spending the money are not connected to the eligibility rules for making contributions. Also, if the account owner is age 65 or older, funds may be withdrawn for any reason and are subject to regular income tax (like an IRA) but not the additional 20% penalty that applies if you use funds for non-medical purposes under age 65.

So there are some wrinkles here.

1. You should not decide based just on taxes. How else can your spouse and child get insurance coverage? Is the HDHP the best option?

If you are working at age 70, and you enroll in a family HDHP, then your wife can contribute to an HSA because she is "covered" by a family plan, even if she is not the "owner" of the family plan. As long as she is not covered by any other type of insurance.

2. Once you own your own HSA, you can use the funds for qualifying medical expenses for yourself, your spouse, and your dependents, no matter what kind of coverage you have. Ability to spend is not connected to eligibility to contribute. If you are covered by Medicare, you CAN reimburse yourself for Medicare premiums you pay (if you choose), but not Medigap insurance. You can also pay for out of pocket expenses for yourself, your spouse and your dependents from your HSA. You can't reimburse yourself for your workplace premiums since they are almost certainly already deducted from your pay pre-tax.

3. If your spouse is "covered" by a family HSA, and has no other medical coverage, her contribution limit for 2026 is the family limit of $8750, plus $1000 catch-up if she is age 55 or older.

4. You or your spouse can use funds from your HSAs to pay for medical expenses for self, spouse, or any dependents. This means tax dependents. A child who is a tax dependent can not contribute to their own HSA, but you can cover their expenses. (Remember, an HSA is owned by one person only.)

Now here's the wrinkle. Because you can cover a child on your medical policy up to age 26, but a child can't be a tax dependent if they are 24 or older (or if they are 19 and older but not a full time student) there is a "window" where the child can be covered by your insurance but is not a tax dependent. In that window, you and your spouse can't pay for their medical expenses from your HSAs, but the child can contribute in an HSA in their own name and then use the funds to reimburse themselves for medical expenses. Their contribution limit would also be $8750 if they are covered by a family plan, and their limit is not reduced by any contributions you or your spouse make. It's a kind of loophole caused by the fact that the age to be a dependent stops at 24 but the age to be covered by parent's insurance is age 26.

@Opus 17 can you please reconfitm the 'wrinkle' paragraph? A child certainly can be a dependent beyond the age of 24, they just can't be a Qualified Child (unless disabled) but they could be a Qualifying Relative. Does that change the advise?

example of a dependent (a Qualifying Relative): A 25 year old child is on the OP's insurance, providing more than 50% of their support costs and the child earns less than $5200.

Correct, a QR dependent can't contribute to an HSA. I would like to think that most 19-26 year olds can earn at least $5500, though, especially if they are not full time students. The case I am thinking about is a child who graduates college and is earning a little money, but is still carried on their parents' insurance until age 26, or a child not in college between the age of 19-26 who works a little but is still covered by their parents' insurance.
