My brother was actually stationed at the Amundsen-Scott South Pole Station as an engineer for 14 months back in 2019-2020. He said the tax situation was handled by their employer (a contractor for the national science foundation) and they just used their permanent US address for tax purposes. He never had to select Antarctica as a country code for anything. The whole system is set up to handle the unique situation of Americans working in a place with no actual government. The funniest part was that he was there during the first COVID lockdowns and said it was the only place on Earth that remained completely COVID-free (since no one could come or go during the winter season). Talk about extreme social distancing!

This is such a fascinating thread! I had no idea there were so many people with actual Antarctica work experience. Reading about your brother's experience at the South Pole Station is incredible - I can't even imagine being that isolated, especially during COVID when the rest of the world was in lockdown. It's really interesting how the tax system handles these unique situations where Americans are working in places that technically don't belong to any country. The fact that they just use their permanent US address makes total sense from a practical standpoint. Thanks for sharing that story!

Does anyone know if there are exceptions to these rules? I'm military and we've rented our house out during deployments. Not sure if the IRS treats military situations differently with the home sale exclusion.

Thanks to everyone who's contributed to this thread - it's been really helpful! I'm in a similar situation to the original poster and was getting confused by the IRS examples too. Based on what I'm reading here, it sounds like the key is whether you establish the property as your primary residence BEFORE renting it out. The IRS basically rewards you for using it as your actual home first, rather than treating it as an investment property from day one. For @Amara Okafor - your situation sounds like you should qualify for the full exclusion since you lived in it for 18 months first before renting it out, and you're back living in it now. The rental period in the middle shouldn't hurt you based on what others are explaining here. One thing I'm still wondering about though - does it matter HOW LONG the rental period was? Like if someone lived in their house for 2 years, then rented it for 10 years, then moved back in for a few months before selling, would they still get the full exclusion as long as they meet the 2-out-of-5 year test at the time of sale?

Did you claim EIC or child tax credit? Those usually trigger reviews

Had the exact same codes last year! The 570/971 combo is super common when you file Head of Household with dependents. Mine took about 6 weeks to clear but I got the full refund plus a tiny bit of interest. The notice they send usually asks for proof of your dependents or income verification. Just respond quickly when you get it and you should be good to go. Hang in there! 💪

Honestly this whole MTM vs non-MTM thing is why I switched to just having everything in a non-MTM account. Yeah I lose some tax advantages for frequent trading but the simplicity is worth it. No more worrying about transfers between accounts or what counts as trading vs investing.

This is a great discussion! I'm in a similar situation but with options instead of stocks. I have some TSLA calls that I bought in my MTM account about 6 weeks ago, and I'm thinking about transferring them to my non-MTM account since I want to hold them longer term now. From what I'm reading here, it sounds like I'd have to recognize any gains on the transfer date even though they're still unrealized. That's actually helpful to know because these calls are up about 60% right now, so I need to factor that tax hit into my decision. Does anyone know if the same "deemed disposition" rules apply to options transfers, or are there any special considerations for derivatives? I don't want to accidentally trigger a bigger tax bill than I'm expecting.

Another approach is to use the DRAFT versions of forms that the IRS posts before final versions. They're at irs.gov/draftforms. They usually post these a few months before final versions. Just remember you can't file draft forms! But you can use them to prepare and then transfer the info to the final form when released.

Thanks everyone for the helpful advice! I was definitely leaning toward just modifying the 2023 form but I'm glad I asked here first. @Jackson Carter your explanation about the forms being year-specific really cleared things up for me. I'll wait for the official 2024 version to be released rather than risk processing delays or penalties. In the meantime, I'll sign up for those IRS e-News subscriptions that @Ella rollingthunder87 mentioned - that sounds like a much better way to stay on top of when new forms are available than constantly checking the website. This community has been so much more helpful than trying to navigate the IRS website on my own!
