One more thing to consider - even if FreeTaxUSA doesn't have a specific form for 3921, you could use the "Additional Information" or miscellaneous income sections to at least note that you received the form and exercised ISOs below the AMT threshold. That way there's at least some record in your tax return if you ever get questioned.

I'm dealing with a very similar situation right now with my 2024 taxes. I exercised some ISOs last year and received Form 3921, but I'm also below the AMT threshold. After reading through all these responses, I think I'm going to take the approach of adding a note in FreeTaxUSA's additional information section mentioning that I received the form but it doesn't affect my current year taxes. One thing I'm curious about - for those of you who have dealt with this before, do you know if there's any specific language the IRS prefers when documenting this kind of situation? I want to make sure I'm being clear that I'm not trying to hide anything, just that the form doesn't create any additional tax liability for this year. Also, has anyone tried reaching out to FreeTaxUSA's support to ask why they don't have better support for Form 3921? It seems like with all the tech companies offering stock options these days, this would be a pretty common situation for their users.

This is so helpful! I've been waiting on mine for weeks and only checking during the day. Going to set some evening reminders now. Did you get any notification from your bank or just happened to check at the right time?

This is actually really good to know! I've been one of those people refreshing constantly during work hours thinking that's when everything gets processed. Just filed my CA return two weeks ago and haven't seen anything yet, but now I know to check in the evenings too. Thanks for posting the exact time - gives me a better idea of when to actually look instead of just randomly checking all day 😅

I'm going through the same thing right now! My transcript updated yesterday showing it was mailed and I'm already obsessively checking the mailbox 😅 From what I'm seeing here, looks like 5-8 days is pretty standard. That USPS Informed Delivery tip sounds clutch - definitely signing up for that today so I can stop driving myself crazy wondering if today's the day!

The wait is so real! I've been in your shoes multiple times and it's torture 😅 Based on my experience, you're looking at about 5-7 business days typically, but I've had them arrive anywhere from 3 days to 10 days depending on USPS volume and your location. One thing that helped me was setting up USPS Informed Delivery (it's free!) - you get email previews of your mail each morning so you'll know the exact day your check is coming instead of checking the mailbox every few hours like a crazy person! Also try to remember that "mailed" doesn't always mean it left the facility that exact day - sometimes there's a 1-2 day processing delay. Hang in there, it's coming! 🙏

I just went through this exact situation a few weeks ago and completely understand the stress! Here's what worked for me: First, don't panic - if your tax software is asking for a PIN from last year, it's because you definitely used one. The software stores this information, so trust what it's telling you. I had the same issue where I couldn't find my new PIN anywhere. What saved me was going directly to the IRS "Get an IP PIN" tool on their website (make sure you're on the official IRS.gov site). Even though you mentioned you have an ID.me account, you might need to go through their identity verification process again for the current tax year. The verification can be a bit tedious - they'll ask for information from previous tax returns, credit accounts, etc. - but once you get through it, your current PIN should display immediately. No waiting period or mailing delays. If for some reason the online tool doesn't work, you can also check if you received a CP01A notice in the mail that you might have missed. Sometimes these get mixed in with other mail or thrown away by mistake. Don't file without the PIN if your software is expecting one - it will definitely get rejected and just create more delays and headaches. The good news is that once you retrieve your PIN, filing should go smoothly from there. Good luck! The online tool really is your best bet for getting this resolved quickly.

I went through this exact same situation earlier this year and totally understand the panic! Here's what I learned that might help: If your tax software is asking for an IP PIN from last year, it's definitely because you used one before - the software has that information stored from your previous filing. So trust what it's telling you, even if you don't clearly remember setting it up. The fastest solution is definitely the IRS "Get an IP PIN" tool on their official website. Even though you already have an ID.me account, you'll likely need to go through their identity verification process again for the current tax year. It can take about 10-15 minutes and they'll ask you questions about your previous tax returns, credit history, etc. Once you complete the verification, your current 6-digit PIN should appear immediately - no waiting for mail or callbacks needed. I was able to get mine instantly and file my return the same day. One thing to keep in mind: if you don't use the PIN when your account is flagged for one, your return will definitely be rejected. The IRS system is expecting that additional security layer, so it's not optional. Don't stress too much about the timeline though - getting your PIN through the online tool is usually pretty quick once you know where to look. You've got this!

One thing that might help ease your concerns about the conversion process - you can always do a partial conversion first to test the waters. Convert maybe $10,000-20,000 initially and see how the tax reporting works out, then do the rest later in the year or next year once you're comfortable with the process. This approach also helps with tax planning since you can better control which tax bracket the conversion income falls into. Plus, if you're worried about making mistakes, starting smaller gives you a chance to work through any issues before converting your entire rollover IRA balance. The tax treatment will be exactly the same whether you convert it all at once or spread it across multiple transactions - the full converted amount (including withholdings) is taxable income, and you get credit for taxes already withheld.

Great question about IRA to Roth conversions! Just to add to the excellent advice already given - make sure you understand the timing aspect too. The conversion is considered complete (and taxable) in the year you do it, regardless of when you actually pay the taxes. So if you convert in December 2024, that's 2024 income even if you don't file your return until April 2025. Also, keep in mind that once you convert, you can't undo it (the recharacterization rules changed a few years ago). So definitely run the numbers on how the additional taxable income will affect your overall tax situation, including potential impacts on things like Medicare premiums if you're close to retirement age. The withholding approach you're considering is totally valid - just remember that money withheld for taxes is gone forever and won't be growing in your Roth. If you have cash available outside of retirement accounts, paying the conversion taxes from there lets you move the maximum amount into tax-free growth.
