Why does TurboTax say I made an excess contribution to my HSA?

[user17711272749]

I retired at the end of September 2025; as an employee I was covered by a high-deductible plan and I made contributions to my HSA.  As a retiree I was also covered by a high-deductible retiree plan; I made a contribution to my HSA in 4Q25 to bring me up to the IRS limit for family coverage (including the catch-up contribution for over-55).  Neither my wife nor I were on Medicare at any time during 2025. 

However, TurboTax tells me that the contribution I made in 4Q25 is an excess contribution.  My total HSA contribution in 2025 is equal to the IRS limit of $9550 (i.e. $8550 family plan + $1000 catch-up).  Everything I can find online says that as long as I'm enrolled in a high-deductible plan, I can make HSA contributions even as a retiree.  What do I have to do so that TurboTax agrees?

my guess might be even Medicare eligibility negates HSA contribution eligibility?

Neither of us was Medicare-eligible in 2025

What did you enter for your insurance coverage? A Family HDHP plan? For all 12 months? If you did, TurboTax would have no way of knowing what other coverage you had.

May I assume that you are 55+? TurboTax would know your age.

Did you have an excess contribution in 2024? If you did not withdraw that excess before April 15 2025, then this excess would carry over to tax year 2025 as a personal contribution, which could easily trigger an excess HSA contribution.

The following is a document that I have put together to describe a number of very common reasons that the taxpayer shows an excess contribution when perhaps they shouldn't:

Why do I have an excess HSA contribution

First, did you have an excess HSA contribution carryover from 2024?

Accidentally indicating that you have an excess is a common occurrence. If one of these does not describe your situation come back and talk to us:

***

One of the purposes of the HSA interview is to determine your annual HSA contribution limit.

As you probably know, the maximum limits in 2025 are:

• $4,300 - individual with self-coverage
• $8,550 - individual with family coverage
• If the HSA owner is 55 or older, then you add $1,000 to these amounts.

However, these limits assume that you were under an HDHP all year. If you left the HDHP during the year or started Medicare or had one of a number of change events, then the limit is reduced. 

There are several major culprits for excess contributions (other than just actually contributing more than the limit). 

First, if you did not complete the HSA interview - that is, go all the way until you are returned to the "Your Tax Breaks" page - the limit still might be set to zero, causing a misleading excess contribution message. 

There are questions all the way to the end of the interview that affect the annual contribution limit.

Second, it is not unusual for taxpayers to accidentally duplicate their contributions by mistakenly entering what they perceive to be "their" contributions into the second line on the "Let's enter your HSA contributions" screen.

Normally, any employee who made contributions to his/her HSA through a payroll deduction plan has the contributions included in the amount with code "W" in box 12 on the W-2. This is on the first line on this screen (above). Don't enter the code W amount anywhere on the return other than on the W-2 page.

Third, if you weren't in HDHP coverage all 12 months, then the annual contribution limit is reduced on a per month ratio. NOTE, this means that you have to indicate when and under what type of HDHP plan you had. Be sure to answer the questions on the screen entitled "Was [name] covered by a High Deductible Health Plan in 2025?".

Fourth, if you had a carryover of excess contributions from 2024, then this carryover is applied to 2025 as a reduction to the 2025 HSA contribution limit, which could cause an excess condition in 2025 as well. But note: if you had an excess contribution in 2024 but cured it by withdrawing the excess in early 2025, then do NOT report an "overfunding" on your 2025 return.

Fifth, the Family limit ($8,550) is for the aggregate of contributions by both taxpayers, even if both taxpayers have their own HSAs. That is, one taxpayer can’t contribute $8,550 to his/her HSA and the other contribute $4,300 to the other HSA – the $8,550 limit applies to the aggregate of all HSA contributions credited to the family (in this case, the excess contributions would be $4,300).

Yes I am 55+, and yes TurboTax knows how much I contributed to my HSA while still employed (from my imported W-2).

Yes we were covered by my employer's employee HDHP family plan thru September, and by my employer's retiree HDHP plan for the last three months of the year. I did not have an HSA contribtion carryover from 2024. The only thing that changed was my status, from employee to retiree.

All I did was deposit the difference between what I contributed while still employed, and my annual max. For some reason TurboTax thinks this is an excess contribution.

broncos: Note that just being eligible for Medicare does not preclude you from being able to contribute to an HSA - you have to actually be covered by Medicare to be precluded.

@Broncos07940 

User: Just to be clear, you entered for the year 2025, that you had Family HDHP coverage for every month in 2025? You see, TurboTax has no way to knowing that you retired.

1. What did you enter as your HDHP coverage for each month on 2025?

2. Did you enter the same for your spouse?

3. How much did you contribute to your HSA on your W-2?

4. What was the size of your personal contribution in the 4th quarter?

5. It seem likely that you made some change in your entries for the first three quarters versus the fourth quarter, or else TurboTax would not have shown excess contributions over the year

I answered that I have an HSA and my wife does not.

TurboTax knew (from my W-2) that my employer and payroll contributions were $7563.
I personally made an additional $1987 contribution in 4Q to bring me up to our over-55 max of $9550.

I answered "Yes" to the HDHP question.

None of the following situations apply, so I left the corresponding checkboxes blank:
[] I had Medicare
[] I overfunded my HSA last year
[] I inherited this HSA
[] I had other company contributions that weren't reported to my W-2 or apply to a previous year
[] I failed to maintain HDHP coverage in 2025 due to death and disability
[] I made contributions to an Archer MSA

I specified that I was covered by a Family plan every month of the year.

I was then asked to specify what type of HDHP coverage I had for each month of 2024 (for some reason); I specified "Family Plan" for each month. Ditto for my wife (she was covered under my Family Plan).

At this point I was told I have an excess contribution of $1987 and was asked whether I plan to withdraw any of it (I said "No"). My HSA Summary screen says I can make any changes if needed, but none of the following values are editable:

Deduction $1,987
Taxable distributions $0
Taxable earnings on excess contributions $0
Tax-free employer contributions $7,563
Excess employer contributions withdrawn $0

This is what I expected (except of course for the "excess contribution" part).  Not sure how to proceed... or to delete this section and start it over.

On your HSA Summary, some thoughts:

1. Yes, the screen says you can edit these numbers, but no you can't. You have to go back into the HSA interview or even to your W-2 to change anything on the Summary.

2. Deduction $1,987 means that you have this deduction on line 13 of Schedule 1 (1040). You can check this. 

3. If #2 is true, then this suggests that you somehow entered this $1,987 contribution twice - one time it was actually deducted and the second amount became the excess.

4. Two possibilities come to mind:

4.A You saw and entered $1,987 on two "Let's enter [name]'s HSA contributions" screens. Since you said your wife does not have an HSA, I assume that you did not see this screen for your wife, but I have to ask.

4.B You had a carryover of excess HSA contributions from 2024 of $1,987. This is entered by TurboTax as a "personal" deduction on your 2025 return on line 2 of your 8889. This is an attempt to "use up" the excess in the subsequent in order to stop the carryover penalty.

I don't remember if you are using the Online or the Desktop version of TurboTax. If you are using the Desktop version of TurboTax, then go to Forms (upper right) and look for form 8889-T. I don't know if the carryover amount will appear on line 2 (it did not used to), but the arithmetic will act as if there is this carryover amount on line 2 even if it is not printed.

If you are using the Online product, then go to the "Let's enter [name]'s HSA contributions" screen and remove the $1,987 from the second line ("personal contributions"). Then continue with the interview and look for two things:

1. You do not see the excess contribution message, and

2. The HSA Summary still shows the "Deduction $1,987" on the first line. As I noted, you can check that this is on your return by looking at line 13 of Schedule 2 (1040).
