You might want to keep documentation from your mom showing this was a gift for your down payment in case your mortgage lender asks questions. They sometimes get weird about large deposits right before a home purchase and want to verify it's not a loan that would affect your debt-to-income ratio.

Thanks everyone for all the helpful responses! This has really put my mind at ease. I was definitely overthinking this situation and getting worried about nothing. It sounds like since this is clearly a gift from my mom (she doesn't expect repayment) and it's under the $18,000 annual exclusion limit, I don't need to report it as income on my tax return. I'll make sure to keep good documentation of the transfers and maybe get a simple gift letter from my mom like someone mentioned, especially since I'm using this for a down payment and my lender might ask questions. It's such a relief to know this won't complicate my taxes - I was already stressed enough about filing for the first time with a home purchase! Really appreciate this community for helping a newcomer navigate this confusing stuff. You all saved me from a lot of unnecessary anxiety!

I've seen partnerships handle this same scenario in different ways. One approach some use is to actually separate the interest component from the ordinary income on the K-1 before it even hits their books. Essentially, they recharacterize a portion of the ordinary income as interest expense (matching the K-1 footnote disclosure), and then apply the 163(j) limitation to that separated amount. This makes the mechanics in the software easier since you now have an actual interest expense line item to disallow. Not sure if this is technically correct though.

I've dealt with this exact situation multiple times, and you're absolutely on the right track. The M-1 adjustment approach is definitely the way to go - it maintains the integrity of the K-1 reporting while properly applying the 163(j) limitation at your partnership level. One thing I'd add is to make sure you're calculating the disallowed amount correctly. Since the lower-tier partnership wasn't subject to 163(j), they deducted the full $270K of interest expense in computing their ordinary income. Your Form 8990 calculation should isolate just the portion that's disallowed under your partnership's 163(j) limitation - it might not be the full $270K depending on your adjusted taxable income. Also, don't forget to prepare the Section 163(j) statement that needs to be attached to your return showing the carryforward amount. Partners will need this information for their own records, and it's required under the regulations. The statement should clearly identify the disallowed amount and its source (the lower-tier partnership). From a practical standpoint in Lacerte, I usually create the M-1 adjustment with a description like "163(j) disallowed interest from [Partnership Name] - see Form 8990" to make it clear for review purposes.

Has anyone considered the Self-Rental Rule implications here? If you personally own the property but rent it to your LLC, and you materially participate in the LLC's activities, the rental income might be reclassified as non-passive. This could affect how losses are treated.

I've been following this thread as someone in a similar situation, and there's been some great advice shared here. One thing I'd add is to make sure you're keeping meticulous records of all LLC activities separate from your personal finances, even if you end up qualifying for the qualified joint venture election. The IRS pays close attention to rental LLCs, especially when the property ownership and business operations are split like yours. Having clear documentation showing the LLC's purpose, meeting minutes (even if it's just you and your spouse), separate bank accounts, and proper expense tracking will help support whatever tax treatment you choose. Also, don't forget about your state tax obligations. Some states require LLC annual reports or franchise taxes regardless of your federal tax election. And if you're in a state with different rules for LLCs, that could affect your federal options too. The suggestions about TaxR.ai and getting professional help make a lot of sense given all the variables involved. This stuff gets complicated fast, and the cost of getting it wrong with the IRS usually exceeds the cost of getting proper guidance upfront.

One thing nobody's mentioned - if you're using the iPhone for product photography, you might want to also deduct photography accessories like a ring light, tripod, maybe even photo editing software if you use it. All of these would be legitimate business expenses too since they directly relate to your Amazon sales activity. I sell on Etsy and deduct all my product photography equipment. Just make sure everything passes the "ordinary and necessary" test for your business. And keep those receipts organized!

Don't forget to consider the timing of your purchase if you're planning to deduct it! If you buy the iPhone late in the tax year, you might want to start using it for business purposes immediately to establish the business use pattern. Also, I'd recommend setting up a separate Apple ID or at least organizing your apps so you can clearly distinguish between business and personal use. Having your photography apps, business communication apps, and Amazon seller app grouped together makes it easier to demonstrate the business purpose if you ever need to justify the deduction. One more tip - if you're taking the business use percentage approach, consider taking screenshots of your photo gallery periodically showing the ratio of business photos to personal ones. It's a simple way to document your usage pattern over time.

Has anyone actually calculated what the earnings portion would be for an excess contribution removal? My understanding is that you need to withdraw not just the excess contribution but also any earnings specifically attributed to those excess funds.

Just to add another perspective on this - I made a similar mistake a few years ago and learned that timing really matters for your options. Since you already withdrew the excess from your account but left it in your husband's, you're looking at paying the 6% penalty on his portion for 2023 and potentially 2024 if it's still there. One thing to consider is whether you qualify for "reasonable cause" penalty relief. The IRS sometimes waives the 6% penalty if you can show the excess contribution was due to reasonable cause and not willful neglect. Being unaware of the income limits when you're used to being eligible could potentially qualify, especially if this is your first time exceeding the limits. You'd need to file Form 5329 to report the excess contribution and request the waiver. The key is providing a clear explanation of why the excess occurred and showing you took steps to correct it once discovered. Worth exploring before just accepting the penalty!
