I went through this exact same confusion last year! The AMT calculations in Schedule D can be really bewildering, especially when you're seeing numbers that don't seem to connect to anything you entered. What helped me was understanding that AMT (Alternative Minimum Tax) is essentially a parallel tax system. Even if you only have capital gains, the software still needs to run the AMT calculation to prove you don't owe it. This is why you're seeing Form 6251 references even though you didn't encounter it explicitly last year - it was being calculated behind the scenes. The "mystery numbers" you're seeing are likely AMT adjustments that get applied automatically based on your income sources and filing status. For example, if you have any depreciation recapture, incentive stock options, or certain other transactions, these create differences between your regular tax basis and AMT basis over time. FreeTaxUSA is generally reliable with these calculations - they've been handling AMT for years and the rules are well-established. My advice is to focus on entering your information accurately and let the software handle the complex AMT math. If you want to dig deeper, you can usually view the actual Form 6251 in the "Forms" section of your software to see the detailed calculations. Don't stress too much about understanding every single number - AMT is one of the most complex areas of tax law, and even tax professionals sometimes need to reference the rules!

I completely understand your confusion with Schedule D and AMT calculations - this is honestly one of the most opaque areas of tax preparation! What you're experiencing is actually very normal behavior from FreeTaxUSA and other tax software. The key thing to understand is that AMT (Alternative Minimum Tax) operates as a completely separate tax calculation that runs parallel to your regular tax return. Even though you only have capital gains to report, the software is required by law to calculate whether you might owe AMT. This is why you're seeing Form 6251 references and mysterious numbers that don't seem connected to your inputs. Think of it this way: the software has to "prove" you don't owe AMT by actually running the full calculation, even if the result is zero. The numbers you're seeing are likely standard AMT adjustments and preferences that get applied automatically based on your filing status and income sources. For capital gains specifically, while the tax rates are often the same under both regular tax and AMT, there can still be differences in basis calculations, timing adjustments, or other technical factors that require separate calculations. My suggestion is to trust FreeTaxUSA's calculations - they've been handling these complex AMT computations for years and are generally very reliable. If you want peace of mind, you can usually view the actual Form 6251 in your software's "Forms" section to see the detailed AMT worksheet, even though understanding every line isn't necessary for most taxpayers.

I went through this exact situation two years ago and want to share what I learned. The estimated tax penalty on Line 38 is one of the most commonly misapplied penalties by tax software, especially when you transition from getting refunds to owing money. Since you received a refund last year, you almost certainly qualify for the "prior year safe harbor" rule. This means if your withholding and estimated payments for this year equal at least 100% of last year's total tax (110% if your AGI was over $150,000), you shouldn't owe any penalty regardless of how much you owe this year. Here's what I'd recommend: Don't just accept H&R Block's "the system calculates it automatically" response. Ask to speak with a supervisor or enrolled agent and specifically mention "prior year safe harbor" and "Form 2210." If they still won't help, you can file Form 2210 yourself after your return is processed to claim the penalty waiver. The IRS will accept your payment even if you don't owe it, but getting your money back later can take months. It's worth fighting this now rather than waiting for a refund that might take half a year to arrive.

I had a very similar experience with TurboTax a few years ago - their software automatically calculated an estimated tax penalty even though I clearly qualified for safe harbor. The problem is that most tax software doesn't automatically cross-reference your prior year return to check if you meet the safe harbor exceptions. Since you got a refund last year, you're almost certainly protected by the "100% of prior year tax" safe harbor rule. This means as long as your withholding this year was at least equal to your total tax liability from last year's return, you shouldn't owe any penalty at all. Don't let H&R Block brush you off with "the system calculates it automatically." Their system is wrong in this case. Ask them to show you exactly how they calculated the penalty and demand they review Form 2210 instructions. If they refuse, you can always file Form 2210 yourself after your return is processed to request the penalty be waived. The frustrating part is that if you just pay it now, getting that $550 back from the IRS could take 6+ months. It's definitely worth pushing back on this before you submit your return.

Has anyone talked about the deadline aspect? You mentioned having an extension, but those military extensions only last so long. Are you using a tax professional or filing yourself? With this complexity, it might be worth getting a CPA who specializes in military transitions.

I went through something very similar when I separated from the Air Force in 2022. The key thing that helped me was getting everything documented in writing from DFAS before filing my taxes. Here's what I'd recommend based on my experience: 1. **File with your W-2 as is** - Your payroll contact is correct that the W-2 reflects the proper reporting to the IRS. The overpayments aren't taxable income since they're considered debt. 2. **Get a debt collection statement** - Request written documentation from DFAS showing the overpayment amount and confirming it's being treated as debt, not income. This protects you if there's ever an audit. 3. **Understand your repayment options** - When you repay, you'll likely only need to repay the net amount (what hit your bank account after taxes). The withholdings stay with the IRS as credits on your return. 4. **Don't wait for DFAS to contact you** - They can be incredibly slow. Proactively starting the debt collection process will give you more control over timing and payment options. The good news is this situation is more common than you think, and the IRS understands how military pay works. Your extension gives you time to get the documentation you need, but don't stress too much about filing "incorrectly" - you're filing with the W-2 as provided, which is exactly what you're supposed to do.

I just went through this exact situation last month! When you have two W-2s like this from the same employer, it's usually because of a mid-year change in tax jurisdictions (which matches your husband's office move). Here's what worked for me: Use the Federal/State W-2 as your primary form in TurboTax. This has all your complete federal wage and tax information. The City/Local W-2 is supplementary and should only be used for the local tax sections. For Box 12 specifically, the differences you're seeing make sense: - The lower Code C amount ($390 vs $1,350) on the City/Local form reflects the reduced life insurance benefit calculation after the move - The Code D difference ($10,900 vs $11,800) shows 401k contributions were slightly different between the two periods - Code AA only appears on the Federal/State form because that's where the complete annual Roth 401k contribution total is reported TurboTax's import feature will likely only grab the Federal/State W-2, so you'll need to manually enter the city tax amounts in the local tax section. Don't worry about "double reporting" - the software keeps federal and local separate. Just make sure you're using the right form for each section!

This is exactly the kind of confusing situation that can happen with mid-year employment changes! You're right to be cautious about which W-2 to use. From what you've described, the Federal/State W-2 should be your primary document for filing. The fact that it has complete state information and higher Box 12 amounts suggests it reflects your husband's full annual earnings and deductions. The City/Local W-2 with lower amounts makes perfect sense given that he stopped paying city taxes in July when the office moved. Those reduced Box 12 amounts (like the $390 vs $1,350 for Code C) reflect the partial year when city taxes applied. When you use TurboTax, enter the Federal/State W-2 as the main W-2 for your husband. If TurboTax asks about local taxes (which it should since you'll indicate he had some city tax withheld), that's when you'd reference the City/Local W-2 for those specific local tax fields. The electronic import feature will probably only pick up one W-2, so you may need to manually verify the local tax information. But this approach should ensure you're reporting the complete annual federal amounts while properly accounting for the partial year of city taxes.

I made $9,400 last year and didn't file. Now I regret it because I checked my W-2 and saw they withheld like $500 in federal taxes that I could've gotten back. Is it too late to file for last year?

For someone in your exact situation (single, 24, $9,200 income, not a dependent), you should definitely file! Even though you're under the $12,950 threshold that requires filing, you'll likely get back every penny of federal income tax that was withheld from your paychecks. Check box 2 on your W-2 - if there's any amount there, that's money the government owes you. Plus, you might qualify for the Earned Income Tax Credit, which could actually give you more back than what was withheld. The 1040 form is straightforward for your situation. You can use the IRS Free File program since your income is well under $73,000, or any free tax software. Don't leave money on the table - file that return!
