Medicare Part A automatically enrolled 6 months ago without notice - can't contribute to HSA now?

Just got the MOST frustrating news from SSA! I'm turning 66 (my FRA) in February and filed for Social Security benefits last month. Got my approval letter today saying payments start in March, but here's the bombshell - the letter says I've been covered by Medicare Part A since SEPTEMBER 2024! How is this even possible when I never received a Medicare card, never got a Medicare number, and had absolutely NO IDEA I was enrolled?? The worst part is I've been contributing to my HSA through my employer all this time, which is apparently illegal if you have Medicare Part A! My HR department never mentioned this, and now I'm worried about tax penalties. Has anyone dealt with this retroactive Medicare enrollment mess? I'm still working full-time and could technically suspend my SS benefits for the first 12 months and also switch to a non-HSA health plan at work, but why should I delay getting MY money just because of this ridiculous retroactive enrollment? The SSA rep I spoke with just said "that's how the law works" and wasn't helpful at all. Does anyone know if there's a way to undo the Medicare Part A coverage for those past months or protect my HSA contributions? I'm so frustrated right now!

Unfortunately, this is one of those weird Medicare rules that catches many people by surprise. Medicare Part A is automatically applied 6 months retroactively when you apply for Social Security benefits at or after FRA. It's called the "retroactive enrollment period" and it's actually written into the law. Regarding your HSA contributions during this period - yes, this is a serious issue. The IRS considers any HSA contributions made while enrolled in ANY part of Medicare (even just Part A) to be "excess contributions" subject to a 6% excise tax for each year they remain in your account. You have a few options: 1. Work with your employer to stop HSA contributions immediately 2. Withdraw the "excess contributions" made since September 2024 (plus any earnings on those contributions) before you file your 2024 taxes 3. If you really want to continue HSA contributions, you could withdraw your Social Security application (if it's within 12 months of filing) but that means delaying your benefits

Thank you for explaining this. I had NO idea this would happen! So if I withdraw the excess contributions before filing taxes, will I avoid the 6% penalty? And should I contact Medicare to get this documented somehow since I never received any Medicare card or info?

OMG this exact thing happened to my husband last year!!! It's INSANE how they don't tell you about this until AFTER the fact. He had been putting $7200 a year in his HSA and then suddenly found out he couldn't do that anymore because of the retroactive Medicare. The worst part was he had to pay back some HSA money AND he missed the deadline to sign up for Part B because nobody told him he was enrolled in Part A! Total nightmare with SSA and Medicare people giving different answers every time we called.

That sounds awful! Did you end up getting everything sorted out? Did he have to pay penalties?

You're right to question the timeline. Medicare Part A retroactive enrollment is typically up to 6 months before application, not before FRA. So if OP applied in January 2025 for February FRA, the retroactive enrollment shouldn't go back further than July 2024. September 2024 would be 4 months back, which is possible but not the full 6 months they could go back.

I had the same issue and spent HOURS on the phone with SSA trying to fix it. It's ridiculous how they do this and don't even bother to tell people! I ended up having to contact a tax professional to help me figure out how to handle the HSA contributions I'd made during those 6 months. Honestly, the whole system is designed to trip people up. One thing I can suggest - get a copy of your Medicare enrollment confirmation in writing. You might need it for tax purposes to prove exactly when your coverage started.

This retroactive Medicare enrollment causing HSA problems is one of the most common issues we see for people reaching FRA. After trying for weeks to get through to SSA on the phone about this exact issue, I found Claimyr (claimyr.com) which got me connected to an agent in under 10 minutes. They have a video showing how it works: https://youtu.be/Z-BRbJw3puU. The agent I spoke with helped me document my Medicare start date and provided an official letter I could show my employer and tax preparer. Saved me hours of frustration.

This is a perfect example of how SSA and Medicare policies don't align well with modern healthcare options like HSAs. Here's what you need to know: 1. For the excess HSA contributions from September-December 2024: Complete Form 8889 with your 2024 taxes and withdraw those excess contributions (plus any earnings on them) before filing your taxes. This should help you avoid the 6% penalty. 2. For your Medicare card: Call the Medicare enrollment line directly at 1-800-MEDICARE to request your card be sent to you. They should have your Medicare number in their system already. 3. For future planning: Since you're still working with employer coverage, you could technically decline Medicare Part B without penalty (you can enroll later during a Special Enrollment Period when you stop working). But Part A is mandatory if receiving Social Security benefits. 4. Documentation: Get a letter from SSA stating your exact Medicare Part A start date for tax purposes. The retroactive enrollment is built into the Social Security Act, specifically to provide maximum coverage to beneficiaries. While well-intentioned, it creates these exact HSA conflicts that weren't anticipated when the laws were written.

This is incredibly helpful, thank you! I'll request that documentation from SSA immediately and talk to my tax person about Form 8889. Do you know if I should expect a Medicare card in the mail automatically, or do I need to specifically request one since I'm already "enrolled"?

It's a big deal because HSA contributions have significant tax advantages that some people rely on for healthcare costs! Plus the retroactive nature means people are getting penalized for something they had no way of knowing about. That's completely unfair.

just wondering - does this retroactive thing affect people who are still working? i turn 66 next year but plan to work till 70. should i not file for ss until i stop working? this seems so confusing

If you're still working and want to continue contributing to an HSA, you should NOT file for Social Security until you stop making HSA contributions. Even if you delay Social Security, you can still enroll in Medicare at 65, but it's not mandatory if you have employer coverage (from an employer with 20+ employees). The key is that once you start Social Security benefits at/after FRA, Medicare Part A is automatic and retroactive up to 6 months, which immediately disqualifies you from HSA contributions.

UPDATE: Called SSA this morning and waited 2.5 hours!! They confirmed I was automatically enrolled in Medicare Part A in September 2024 and there's no way to undo it. The rep said my Medicare card was supposedly mailed in September but I never got it. They're sending a new one now. I've also contacted my HSA administrator to figure out how to handle the excess contributions. What a mess!!

Good news on getting confirmation. Make sure to also: 1. Get a copy of your Medicare Benefit Verification Letter (shows exact enrollment date) 2. Notify your employer's benefits department immediately 3. Calculate exactly how much you contributed to your HSA from September-December 2024 4. Consult with a tax professional about Form 8889 and how to report/withdraw the excess contributions The 6% excise tax applies for each year excess contributions remain in your account, so handling this promptly will minimize any penalties.

Did your SS benefit letter show your Medicare number? Mine did, in the top right corner. You can use that number to create a Medicare.gov account and start managing your Medicare online even before your card arrives.

Yes! I just checked and there is a number there. I didn't realize that was my Medicare number. Thank you for pointing that out. I'll set up the online account today.
