W2 Box 12 Code W - HSA Contributions Confusion - Am I Getting This Right?
I'm feeling a bit confused about my W2 and HSA contributions. On my W2, Box 12 Code W (HSA Contributions) shows $3,600. These contributions were all from my own pocket, not from my employer. My employer didn't contribute anything to my HSA in 2024. Is this an error on the W2? Or is it normal for Box 12 Code W to include both employee and employer contributions combined? The confusing part is that TurboTax seems to be treating these as employer contributions. For Form 8889, it's showing: Line 2 - $0 Line 8 - $9,300 Line 9 - $3,600 Line 12 - $5,700 But I'm thinking Line 2 should be $3,600 and Line 9 should be $0? Maybe they're considered part of a Cafeteria plan that I don't understand? I feel like this might be costing me some tax deduction. If I'm right and there's an issue, how do I fix it in TurboTax?

This is actually a common source of confusion with HSA reporting! When HSA contributions are made through payroll deduction (taken directly from your paycheck before taxes), they're reported in Box 12 with Code W on your W-2, even though they're YOUR contributions, not your employer's. For tax purposes, contributions made through payroll deduction are treated as "employer contributions" even though the money is coming from your salary. This is because they were never included in your taxable income in the first place (they were pre-tax deductions). Your Form 8889 actually looks correct. Line 2 should be $0 because your contributions were made pre-tax through payroll. Line 9 shows your pre-tax contributions ($3,600) and you're not losing any tax benefit. The deduction on Line 13 is only for contributions you made with after-tax dollars (which you didn't do). It's confusing terminology, but the tax treatment is correct!

•Wait, so if I contribute to my HSA outside of payroll (like directly transferring money from my checking account to my HSA), would that show up differently on my W2? And would I actually get a deduction for that on line 13 instead? Also, what's the advantage of doing it one way vs the other if the tax benefit is the same?

•If you contribute directly to your HSA from your checking account (post-tax), it won't show up on your W-2 at all. You'd report those contributions yourself on Form 8889 Line 2, and then you'd get the corresponding deduction on Line 13. The end result is the same tax benefit - your HSA contributions aren't taxed. The main advantage of payroll deduction is that you also save on FICA taxes (Social Security and Medicare taxes, which are 7.65%). When you contribute directly from your checking account, you get the income tax deduction but you've already paid FICA taxes on that money. So payroll deduction actually saves you a bit more in taxes overall!

I had a similar issue last year and found the tool at https://taxr.ai super helpful. I uploaded my W-2 and other tax documents, and it flagged this exact HSA situation. It explained that when contributions are made through payroll deduction, they show up in Box 12W but are considered "employer contributions" for tax purposes even though they're coming from your salary. The tool walked me through why my 8889 form looked similar to yours and confirmed it was correct. It saved me from accidentally changing things that would have flagged an audit. The nice thing was that it explained everything in plain English instead of tax jargon.

•Does it work with TurboTax files? I'm halfway through my return but now I'm worried about other stuff being wrong. Can it check if everything is correct or just HSA stuff?

•Is this an ad? Seems sus that there's a magical tool that solves exactly this problem lol. Has anyone actually used this and can verify it's not just trying to get our tax info?

•It works with basically any tax documents including PDFs of your forms or even TurboTax exports. I uploaded my entire return and it flagged several issues, not just the HSA stuff. It showed me where my mortgage interest deduction was missing some eligible expenses too. No, definitely not an ad! I was skeptical too at first, but it's legitimate. It's more of a review tool that checks your work rather than a full tax preparation software. It helped me identify several things that TurboTax got wrong or that I had entered incorrectly.

Ok I feel like I need to apologize for being so skeptical in my comment. I actually tried the taxr.ai tool after my last comment and it was surprisingly good. I uploaded my documents including my HSA info and W2s, and it identified a similar situation with my HSA contributions that I totally would have messed up. It also found that I was eligible for a savers credit that TurboTax somehow missed which is adding about $400 to my refund. The explanations were super clear too - not the usual tax gibberish. Sorry for being a doubter!

Anyone else here spend hours trying to get through to the IRS about HSA questions? I was stuck on hold for literally 3 hours trying to sort out a similar HSA issue last week before giving up. Then I found this service called Claimyr (https://claimyr.com) that got me connected to an IRS agent in about 15 minutes. You can see how it works in this video: https://youtu.be/_kiP6q8DX5c The agent I talked to confirmed that Box 12 Code W includes both types of contributions, and that my Form 8889 was filled out correctly with pre-tax payroll deductions showing on line 9, not line 2. Saved me from filing an incorrect return and potentially triggering an audit.

•How does this actually work? Do they just call the IRS for you? Can't I just do that myself if I'm patient enough?

•Yeah right. No way this actually works. The IRS is notoriously impossible to reach. If there was a magic way to skip the line everyone would be using it.

•They don't call for you - they use technology to monitor the IRS phone lines and then call you when they detect an opening. It's like having someone wait on hold for you, but automated. When they detect an agent is available, they call you and connect you directly. It absolutely works! That's why I shared it. I was skeptical too, but I had already wasted hours trying to get through on my own. The IRS actually has different hold queues and variable staffing throughout the day, and their system knows the patterns and optimal times to call. Way better than me hitting redial for hours hoping to get lucky.

Alright I'm back to eat crow again. After being skeptical about both services mentioned in this thread, I tried Claimyr too because my frustration with the IRS was at an all-time high. Spent 3 days trying to reach them about this HSA issue plus another problem with a missing stimulus payment. Not only did I get through in under 20 minutes, but the IRS agent I spoke with was actually super helpful. She confirmed everything about the HSA Box 12 Code W situation AND helped me track down my missing stimulus payment which is now being processed. Won't be using the regular IRS line ever again.

If you contributed through payroll deduction, your employer should have also provided you with a letter or statement showing how much was withheld from your paychecks for the HSA. That's a good cross-reference to check against the W-2. Also, there's a limit to how much you can contribute annually - $3,650 for individual coverage or $7,300 for family coverage for 2024, plus an extra $1,000 if you're 55 or older. Make sure your total doesn't exceed these limits or you'll face a 6% excess contribution penalty.

•I did get a statement from my HSA provider (HealthEquity) that shows exactly $3,600 in contributions for the year, which matches the W2 Box 12W amount. And I'm under the family coverage limit, so I think I'm good there. But I'm still confused about why TurboTax is categorizing these as employer contributions when they came from my paycheck. Should I just leave it as is since everyone is saying the tax treatment is the same either way?

•You should definitely leave it as is. TurboTax is correctly categorizing them based on how the IRS views these contributions. Even though the money came from your paycheck, pre-tax payroll deductions are treated as "employer contributions" for reporting purposes. The end result is exactly the same - you're getting the full tax benefit. If you were to change this in TurboTax, you'd potentially be claiming the same deduction twice, which could trigger an audit. The statements matching your W-2 Box 12W amount confirms everything is being reported correctly.

One thing nobody mentioned - did you set up your HSA yourself or through your employer? If you set it up through your employer, they might have a cafeteria plan (Section 125 plan) where your contributions are considered employer contributions for tax purposes, even though they're deducted from your pay.

•This is exactly right. Most workplace HSAs are part of a Section 125 Cafeteria Plan, which is why they get this tax treatment. It's actually beneficial because you avoid BOTH income tax AND payroll taxes (FICA) on those contributions. If you contributed directly to your HSA outside of payroll, you'd still get the income tax deduction but you'd have already paid FICA taxes on that money.

Just wanted to add another perspective here - I'm a tax preparer and see this HSA confusion ALL the time during tax season. The key thing to remember is that Box 12 Code W on your W-2 shows the TOTAL amount that went into your HSA through payroll deduction, regardless of whether you think of it as "your" money or "employer" money. When contributions are made pre-tax through payroll (which yours were), the IRS considers them "employer contributions" for Form 8889 purposes. This is actually BETTER for you tax-wise because you're avoiding both income tax AND the 7.65% FICA taxes (Social Security + Medicare). Your TurboTax is handling this correctly. Don't second-guess it or you might end up double-claiming deductions. The fact that your HSA provider statement matches your W-2 Box 12W amount ($3,600) confirms everything is being reported properly. You're getting the full tax benefit - just in a different way than you initially expected!

•Thank you so much for that clear explanation! As someone who's new to HSAs, this whole thread has been incredibly helpful. I was getting ready to mess with my TurboTax entries because I thought there was an error, but now I understand the pre-tax payroll deduction system makes perfect sense. One quick follow-up question - if I wanted to contribute MORE to my HSA next year (still under the limits), would it be better to increase my payroll deduction amount rather than making additional contributions from my bank account? Sounds like the FICA tax savings make payroll deduction the better choice?
