Quick tip from someone who dealt with this exact issue: If your employer refuses to issue corrected W-2s, you can actually file Form 8889 (Health Savings Accounts) correctly regardless of what your W-2 says. Line 2 of Form 8889 asks for employer contributions to your HSA, which you should fill out accurately even if Box 12W on your W-2 is wrong. This form becomes part of your tax return and shows the IRS the correct contribution amounts. I've done this for two tax years without any issues. Just keep your HSA statements showing all contributions as backup documentation.

I went through this exact same situation about two years ago and can confirm you're absolutely correct about the Box 12W reporting requirements. Both employee and employer HSA contributions must be included in that box. Here's what I learned from my experience: Start by sending a polite but firm email to your former employer's payroll department explaining the error and citing IRS Publication 969. Include specific dollar amounts and tax years affected. Give them about 30 days to respond. If they cooperate, they'll issue W-2c forms for the affected years. If they don't, you have two solid options: file Form 4852 (Substitute W-2) or ensure you complete Form 8889 accurately on your tax returns regardless of the W-2 error. Keep all your HSA statements as documentation. The good news is that since HSA contributions are pre-tax whether they come from you or your employer, this reporting error likely didn't affect your actual tax liability. The IRS is mainly concerned with contribution limit violations and improper deductions, neither of which applies to your situation. I'd recommend getting the corrected W-2s if possible for clean records, but don't stress too much about amending past returns if your tax liability wasn't affected. Just make sure you have good documentation in case of future questions.

Fyi - I tried doing this with TurboTax last year and their software didn't properly support Form 8919. Ended up having to switch to TaxAct at the last minute. Glad to hear FreeTax USA supports it better!

I went through this exact situation two years ago and can confirm FreeTax USA does support Form 8919. Here's what worked for me: Log into FreeTax USA, go to the "Income" section, then look for "Other Income" or "Miscellaneous Income." There should be an option for "Uncollected Social Security and Medicare Tax" or you can search for "8919" directly in their help search. One important tip - make sure you have your employer's EIN handy when filling out the form. You'll also need to calculate the Social Security and Medicare taxes that should have been withheld (7.65% of your wages). The form will walk you through this calculation. For Form SS-8, as others mentioned, that's filed separately. You can download it directly from IRS.gov and mail it in. Don't wait on the SS-8 determination to file your taxes though - you can still file with Form 8919 using Code G while the determination is pending. Document everything now while it's fresh in your memory - work schedule requirements, equipment provided, training received, etc. This will be crucial for your SS-8 submission.

This is really helpful information everyone. As someone who's been through a complex audit situation, I can confirm that having proper documentation and understanding the process makes a huge difference. One thing I'd add is that the IRS distinguishes between different types of "intent" when evaluating fraud. They look for specific intent to evade taxes (which requires fraud penalties) versus general intent to underreport (which might only warrant accuracy-related penalties). The key evidence they examine includes whether you had knowledge of a legal duty, took affirmative steps to conceal income or inflate deductions, and showed a pattern of underreporting over multiple years. From my experience, being proactive and cooperative during the examination process goes a long way. Even if there are legitimate errors in your returns, demonstrating good faith efforts to comply with tax laws can influence whether the IRS pursues fraud penalties versus treating issues as negligence or substantial understatement. The civil fraud penalty is severe (75% of the underpayment attributable to fraud), so the IRS doesn't apply it lightly. They need to meet that "clear and convincing evidence" standard, which is higher than the typical civil burden of proof.

One aspect that hasn't been covered yet is the appeals process specifically for civil fraud penalties. If the IRS does propose a fraud penalty after their examination, you have several options before it becomes final. You can request an appeals conference where an independent appeals officer (not involved in the original examination) reviews the case. Appeals officers have the authority to settle fraud penalty cases if they believe the IRS position isn't strong enough to sustain the "clear and convincing evidence" standard. I've seen cases where appeals officers reduced fraud penalties to accuracy-related penalties (20% instead of 75%) when they felt the evidence showed negligence or substantial understatement rather than intentional fraud. The appeals process is often more flexible than people realize - they can consider the hazards of litigation and whether the IRS would actually prevail if the case went to Tax Court. If you disagree with the appeals determination, you can still petition Tax Court before paying any of the assessed penalties. In Tax Court, the burden is on the IRS to prove fraud by clear and convincing evidence, and you get a real trial with witness testimony and document evidence. Many taxpayers don't realize they have this option to contest fraud penalties in court rather than just paying them.

Since no one mentioned it yet - don't forget that 2025 tax rules now allow each qualifying child to potentially get you up to $2,000 in tax credits (that's the increased amount after the recent tax law changes). So make sure whoever claims each child can actually benefit from the full credit amount. If your girlfriend doesn't have enough tax liability due to her part-time work, she might not be able to claim the full child tax credit amount even though she's eligible to claim your son. Something to consider when deciding who claims which child!

Great question! I was in a nearly identical situation a couple years ago. One thing that really helped me was getting everything organized early in the year rather than scrambling at tax time. Since you're paying the mortgage and most household expenses, you should definitely qualify for Head of Household status when claiming your daughter. Just make sure you're tracking everything - I started keeping a simple monthly log of who paid what, which made things so much clearer when it came time to file. Also worth noting that the IRS has gotten stricter about auditing HOH claims in recent years, especially when there are multiple taxpayers at the same address. But if you legitimately pay more than 50% of household costs and have proper documentation, you should be fine. The key is being able to prove your contribution level if they ever ask. One last tip - consider having a quick consultation with a tax professional this year to make sure you're set up correctly going forward. It's much easier to establish the right pattern from the beginning than to fix problems later!

Has anyone used the IRS Form 8801 (Credit for Prior Year Minimum Tax) worksheet to calculate this? I think that's where you'd see how much of your prior AMT can be used this year. In my experience, the credit can be limited if your current year regular tax isn't sufficiently higher than your tentative minimum tax.

This is a really common confusion with ISOs and AMT! The key thing to understand is that AMT adjustments are tied to specific shares, not transferable between different ISO exercises. Since you exercised different ISOs in 2022 (which triggered AMT) versus the ones you sold in 2023, you cannot adjust the cost basis of the 2023 sale using the 2022 AMT payment. Each ISO exercise creates its own AMT adjustment that only applies to those specific shares when sold. The AMT credit you're seeing in TurboTax is separate from basis adjustments. This credit can only be used in years when your regular tax exceeds your tentative minimum tax (AMT). If it seems smaller than expected, it's likely because your 2023 tax situation is limiting how much you can use - the unused portion will carry forward to future years. For the tender offer complication, make sure you're reporting the correct cost basis for the shares you actually sold (without any AMT adjustment since those weren't the shares that triggered AMT). The different companies handling the transactions shouldn't affect the tax treatment, but you'll want to ensure you have accurate documentation of your original exercise dates and prices. Consider reviewing Form 8801 to see exactly how your AMT credit is being calculated and limited. The math can be tricky but it will show you why you're only able to use a portion of your available credit this year.
