This is a really tricky situation and I appreciate everyone sharing their experiences. I'm dealing with something similar but from a different angle - my self-directed IRA owns land that I was planning to develop, but after reading all these responses I'm wondering if I should pivot entirely. One thing I haven't seen mentioned is the timing aspect of UBIT. Does anyone know if the IRS has a specific threshold for what constitutes "development" versus "improvement"? For example, if I just put in utilities and a gravel pad for an RV rental instead of building a full structure, would that potentially avoid crossing into the development/active business territory? Also, @Gavin King, your point about running the numbers is spot on. I think a lot of people (myself included) get caught up in the tax-deferred growth benefits without actually calculating whether the UBIT complexity is worth it. Have you found any good resources or spreadsheets for modeling these scenarios? I'd love to run my own numbers before making any irreversible decisions.

I've been following this thread closely as someone who went through a similar decision process with my self-directed IRA real estate investment. One thing that really helped me was getting clear on the IRS's actual definition of what constitutes "development" versus passive real estate investment. From my research and consultation with a tax attorney who specializes in ERISA law, the key distinction isn't just about building something new - it's about the level of activity and business operations involved. Even buying an existing rental property can potentially trigger UBIT if you're actively managing it as a business (like doing significant renovations, marketing, tenant screening, etc.) rather than hiring a third-party management company. In your case, Joshua, since you're talking about building from scratch AND planning to manage it as an AirBNB, you're definitely in active business territory. The AirBNB aspect alone - with the frequent turnover, cleaning, guest communication, marketing - is exactly the kind of active management that triggers UBIT concerns. One alternative I haven't seen mentioned: Could you partner with a qualified third party (not a disqualified person under IRA rules) who would handle all the development and ongoing management? Your IRA could be a passive investor in their project rather than the active developer. This might help you achieve your real estate exposure while staying in the passive investment lane. The math really does matter here though. Sometimes the simplest solution is the best one, even if it means taking the distribution penalty.

If anyone else is confused about timezones like me, I found that most tax software automatically adjusts for your timezone based on your location. I used TurboTax last year and it showed a countdown timer with my local deadline. Just make sure your address info is correct in the software!

Great question about time zones! As someone who's dealt with this exact situation before, I can confirm that Carmen is absolutely right - it's based on your current legal residence, not where your income was earned. Since you're living in Colorado, your deadline is 11:59 PM Mountain Time on October 15th. One thing I'd add is to double-check that your current address is correctly listed on your tax return, since that's what the IRS uses to determine your time zone. Also, given that you're cutting it close, I'd strongly recommend not waiting until the very last minute on Tuesday evening. The e-filing systems can get overwhelmed on deadline day, and if there are any technical issues or if your return gets rejected for any reason, you might not have time to fix it and resubmit. Maybe consider trying to wrap it up during your lunch break or earlier in the evening if possible? Better safe than sorry with the IRS!

Lots of good advice here already, but I'll add one thing nobody's mentioned: If you decide to go the Schedule C route this year (which seems smart for a partial year), you should still open a separate business checking account immediately for your 1099 income. Keep all business income and expenses separate from your personal finances. This will make your tax prep WAY easier and give you a clean start if you decide to form an S-Corp next year. Plus, maintaining this "business separation" is good practice regardless of your legal structure. Also, start making quarterly estimated tax payments! As a 1099 contractor, you don't have withholding anymore. Set aside roughly 30-35% of your contractor income for taxes (federal, state, and self-employment) and make payments through the IRS Direct Pay system. First-year contractors often get hit with a shocking tax bill plus underpayment penalties if they don't do this.

I'm confused about something - does forming an S-Corp mean you automatically get taxed as an S-Corp? I thought you could have an LLC but elect S-Corp taxation? Is that the same thing or different?

Anyone else remember the old days when we had to actually mail paper returns with a postmark by midnight? I once drove to the post office at 11:45pm on April 15th and there was a line of cars around the block! Now we're all stressing about electronic timestamps lol.

Don't panic! You're almost certainly fine. The IRS uses your local time zone for the filing deadline, so if you submitted at 11:23pm Pacific Time on April 15th, you made the deadline with 37 minutes to spare. The April 16th date on your confirmation is likely just because the tax prep service's servers are running on Eastern Time (where it was already past midnight when you filed). What matters to the IRS is the actual electronic submission timestamp with your local time zone info, not what's displayed on the confirmation page. If you want peace of mind, you can check your "Where's My Refund" status on the IRS website in a few days - once it shows up there, you'll know your return was accepted and processed normally. But based on what you've described, you should be all set!

Anyone know if the OP can just file without the spouse this year (as married filing separately) to meet the deadline, then amend later when the ITIN comes through? Would avoid any concerns about the deadline entirely.

Just to add some reassurance here - I went through this exact situation two years ago with my spouse's ITIN application. Filed about a week late due to similar circumstances with Acceptance Agent availability, and since we were expecting a refund, there were absolutely no penalties or issues. The key thing to remember is that the IRS isn't in a hurry when they owe YOU money - the penalties only kick in when you owe them. Your refund will be delayed by the ITIN processing time (took about 9 weeks in our case), but filing a day or even a week late won't add any additional delays or costs. Don't stress about it - get your W-7 completed properly rather than rushing it. A correctly submitted ITIN application is way more important than meeting the extension deadline by one day when you're getting a refund anyway.
