Just wanted to share my experience from last year - I was in the exact same situation as you @c0a759d0a949! I had my paper 1040 ready to go but got so confused about the mailing addresses. After reading through all the conflicting info online, I ended up calling my local post office directly and they confirmed that the Ogden, UT address (Department of Treasury, Internal Revenue Service, Ogden, UT 84201-0002) is correct for California residents filing without payments via regular mail. I sent mine with certified mail for about $4 extra and got confirmation it was delivered within a week. The IRS processed my return normally and I got my refund without any issues. Don't overthink it - the address you found on the IRS website is the right one! Just make sure you're not including any payment checks, otherwise you'd need the Cincinnati address that others mentioned. If you're still worried about it, your local post office can double-check the address for you when you go to mail it. They deal with tax returns all the time during filing season.

I just went through this exact same situation last month! The confusion is totally understandable because there really are different addresses depending on how you're sending it. Since you're in California and filing a Form 1040 without a payment, the address you found is correct for regular USPS mail: Department of Treasury Internal Revenue Service Ogden, UT 84201-0002 The UPS employee was right that they can't use this address - private carriers like UPS and FedEx need the street address version, which would be: Internal Revenue Service 1973 Rulon White Blvd. Ogden, UT 84201 My advice? Just stick with regular USPS since you already have the correct address. You can even do certified mail for a few extra dollars if you want tracking and proof of delivery. I did that and had zero issues - got my refund processed normally. Don't stress about it too much, you've got the right info!

Quick question - I'm in a similar situation but my LLC is taxed as an S-Corp. Does that change what I need to file if there was no activity?

This is a great question that a lot of new LLC owners face! Just to add another perspective - if you're thinking about keeping the LLC for future use, you might want to consider the ongoing costs vs. the hassle of forming a new one later. In some states, the annual fees are pretty minimal (like $50-100), so it might be worth keeping it active if you think you'll use it in the next few years. But in states like California with that $800 annual fee, it's probably better to dissolve it and just form a new one when you actually need it. Also, make sure you're not missing any deadlines! Some states have specific timeframes for when you need to file annual reports or dissolve the LLC to avoid penalties. I learned this the hard way when I forgot about a deadline and got hit with late fees even though my LLC never made a penny. The IRS filing requirements are definitely confusing for inactive LLCs, but better to be safe and file the appropriate forms with zeros than risk penalties later.

5 Has anyone used an online tax program like TurboTax for reporting inheritance stuff like this? I'm wondering if they handle this situation correctly or if I need to see a professional.

Just want to add another perspective here - I went through something very similar when my grandmother passed and left her property to multiple heirs. The stepped-up basis rule that others mentioned is absolutely correct, but make sure you keep excellent records of everything. One thing I wish someone had told me: if there were any improvements or expenses related to settling the estate (like repairs needed before the sale, legal fees for the estate, etc.), those might affect your basis calculation. Also, if there was any time gap between your father's passing and when the property was actually distributed to you heirs, you might need to consider whether there was any appreciation or depreciation in that period. The 1099-S you received is just the IRS making sure they know money changed hands - it doesn't necessarily mean you owe taxes on it. But definitely report it properly on Schedule D and Form 8949 as others have mentioned. When in doubt, it's worth consulting with a tax professional who deals with estate issues regularly.

One thing to consider with Airbnb specifically - if you're renting for short periods and providing substantial services (like breakfast, cleaning during stays, etc.), the IRS might classify this as a "nonrental activity" instead of a passive rental activity. This could actually work in your favor. If you're providing substantial services beyond just the basic rental, you might qualify under different rules and potentially avoid some passive activity limitations. Your daily maintenance might qualify here. I'd recommend keeping a detailed log of all the services you provide and time spent. This documentation could be crucial if you're ever audited.

Has anyone used TurboTax for reporting Airbnb income? I'm in the same situation and wondering if their software handles these passive activity rules correctly or if I need to go to a CPA this year.

Different states have different rules for state income tax on capital gains from home sales. What state are you in? Some states follow federal rules but others have their own rules for exemptions.

The employment-related partial exclusion should definitely work for your situation! Just a heads up though - make sure to keep detailed records of everything related to your job change and the timeline of events. The IRS can be pretty thorough if they decide to review your return later. One thing I'd recommend is getting something in writing from your new employer that confirms the job required you to relocate, even if it's mostly remote. An email from HR or your manager stating that the position necessitated the move to your new location could be valuable documentation. Also, since you mentioned the job is "mostly remote," make sure your offer letter or employment agreement clearly indicates where your official work location or home office is considered to be. With your numbers ($30K gain vs. $229K prorated exclusion), you're well within the safe zone, but having rock-solid documentation will give you peace of mind if any questions come up down the road.
