Does Money from Selling My Father-in-law's Home Count as Income for Tax Purposes?
My partner and I are trying to figure out the tax situation with my soon-to-be father-in-law. We've been financially supporting him for years, spending thousands each month beyond his $950 Social Security check that barely covers one week of his home care. Earlier this year, we had to sell his house because it was heading into foreclosure. The situation was complicated - he originally bought the place for $35,000 back in the day, paid off that first mortgage in 1996, but then took out a second loan for $25,000 a few years later. He refinanced to an interest-only loan with this massive balloon payment due at the end. After paying on this second loan for nearly 30 years at a ridiculous 11% interest rate, he somehow still owed over $30,000 when we sold, with $950 monthly payments that never touched the principal. We managed to sell the house for $85,000. After paying off the mortgage and closing costs, he walked away with about $48,000. My question is: what part of this money counts as income for tax purposes? Is it the full $85k sale price? Just the $48k he actually received? Or maybe just the difference between the sale price and what he originally paid (around $13k)? Or is none of it income since he's actually paid well over $150,000 in mortgage payments over the years? We were planning to claim him as a dependent before this house sale happened, but now I'm not sure if that's even possible. Any help figuring this out would be greatly appreciated!

The good news is that the proceeds from selling a primary residence usually get favorable tax treatment! For your father-in-law's situation, here's what you need to know: The taxable amount isn't the full sale price or even the amount he received after paying the mortgage. It's the difference between the selling price ($85,000) and his "basis" in the home. His basis is typically what he originally paid ($35,000) plus any qualifying improvements he made over the years (additions, renovations, new roof, etc.) minus any depreciation taken. If he lived in the home as his primary residence for at least 2 of the last 5 years before selling, he can exclude up to $250,000 of the gain from his income ($500,000 for married couples). Based on your numbers, his gain would be approximately $50,000 ($85,000 minus $35,000), assuming no qualifying improvements. This would be fully excluded from income under the $250,000 exemption. As for claiming him as a dependent, the home sale proceeds don't count as income for the support test if the money isn't used for his support. However, if he uses that money for his own support (like paying for his care), then it would count as self-support for the dependent test.

•Thanks for the explanation. But I'm confused - does the $48k he got after paying off the mortgage count against the "support test" for claiming him as a dependent even if he doesn't spend it? Like if we keep that money in a separate account just for emergencies but continue paying all his bills ourselves?

•For the support test, what matters is who actually pays for his support expenses during the year, not who has money in the bank. If you and your partner are still paying more than half of his total support costs (housing, food, medical care, etc.) and his money just sits in an account unused, you could still potentially claim him. If he does use some of that money for his own support, you'll need to calculate the total support provided and ensure you're still providing more than 50%. Remember that for the dependency exemption, his gross income (excluding tax-exempt income like Social Security in many cases) must also be below the exemption amount, which is something to check as well.

After dealing with a similar situation with my mom's house last year, I found this amazing AI tool called taxr.ai that was super helpful. I was completely confused about capital gains and basis calculations, and the IRS guidance online was almost impossible to understand. I uploaded the sales documents and my mom's old records to https://taxr.ai and it analyzed everything, explained what counted as improvements to the basis, and calculated exactly what portion was taxable. It even told me which forms to use and provided step-by-step instructions for reporting it correctly. Saved me from making a costly mistake since I almost reported the wrong basis amount!

•How accurate was it compared to what an accountant would tell you? I've been burned by tax software before that missed deductions I was eligible for.

•Does it work for complicated situations? My parents converted part of their house to a rental for a few years, then moved back in, and now they're selling. Not sure if the capital gains exclusion applies to the whole thing.

•It was surprisingly accurate! I actually had my accountant review everything afterward, and she confirmed all the calculations were correct. She was impressed and said it saved her time too. For complicated situations like partial rentals, I found it handled those well. It asks specific questions about how the property was used over time and calculates the portion that qualifies for exclusion. It also explains about depreciation recapture if part of the home was used for business. My situation involved some home office use, and it walked me through exactly how to handle that.

Just wanted to follow up about my experience with taxr.ai since I decided to try it after seeing it mentioned here. It was actually really helpful for my parents' complicated home sale situation! I uploaded their documents and answered questions about the rental history, and it broke everything down into clear sections - what portion qualified for the capital gains exclusion and what didn't. It even identified some home improvements they'd made that increased their basis that we hadn't thought to include. The step-by-step guidance made a huge difference, especially for calculating the depreciation recapture on the rental portion which was the most confusing part. Definitely worth checking out if you're dealing with a home sale that's not straightforward!

If you're still having issues understanding your specific tax situation, you might want to speak directly with the IRS. After my mother passed and I had to sell her house, I needed clarification on some inheritance basis rules that even my accountant wasn't 100% certain about. I tried calling the IRS for weeks - always busy signals or 2+ hour hold times before disconnecting. Then I found this service called Claimyr (https://claimyr.com) that somehow got me through to an actual IRS agent in about 20 minutes! You can see how it works in this video: https://youtu.be/_kiP6q8DX5c The agent I spoke with was actually helpful and walked me through exactly how to handle the basis step-up for an inherited home on my tax return. Saved me thousands in potential capital gains taxes.

•How does that even work? I thought it was impossible to get through to the IRS without waiting forever.

•Sounds like a scam. No way someone can magically get you to the front of the IRS phone queue. They probably just connect you to some "tax expert" who isn't actually with the IRS.

•It's actually a legitimate call-back service. Instead of you sitting on hold, their system waits in the queue for you and calls you when it's your turn. I was skeptical too, but it actually connected me to the real IRS queue - I could tell because the agent verified my identity using the standard IRS protocol and could access my tax records. As for how it works, from what I understand, they have an automated system that navigates the IRS phone tree and stays on hold so you don't have to. When they reach an agent, they connect the call to your phone. It's essentially like having someone else wait in line for you.

I need to update my previous comment about Claimyr because I actually tried it yesterday out of desperation. I've been trying to resolve an issue with a misapplied payment for MONTHS with no luck getting through to anyone at the IRS. I was completely convinced it was going to be a waste of time or some kind of scam, but I was honestly shocked when I got a call back connecting me to an actual IRS representative in about 30 minutes. The agent was able to look up my account, confirm they had misapplied a payment to the wrong tax year, and initiate the correction right there on the phone. After literally months of frustration and worry about penalties accumulating, the whole thing was resolved in one phone call. I'm still surprised it actually worked, but figured I should correct my skepticism since it legitimately saved me from what was becoming a nightmare situation.

One thing that hasn't been mentioned yet about the home sale - make sure to check if your father-in-law qualifies for any medical expense deduction for improvements made to the house. If any modifications were made to accommodate a medical condition (wheelchair ramps, grab bars, etc.), those can sometimes be deducted as medical expenses if they weren't already used to increase the basis in the home. Also, regarding the support test for dependency - remember that medical expenses, including in-home care that you mentioned, count heavily toward the support calculation. Given how expensive that care is, it sounds like you're likely providing well over 50% of his total support even with the home sale proceeds.

•Thanks for mentioning this! We actually did install some grab bars and a walk-in shower about two years ago but I didn't think of that as something tax-related. About how much of his care costs would qualify toward the support test? The in-home aide costs around $4,200/month and we're paying for all of it.

•The in-home care costs absolutely count toward the support test! If you're paying $4,200/month, that's over $50,000 per year just for that care, which is substantial. All of that would count toward your support calculation. For the medical modifications, if they were medically necessary (prescribed or recommended by a healthcare provider), they could potentially be deductible as medical expenses if you itemize deductions. However, these would need to exceed a certain percentage of your adjusted gross income along with other medical expenses to get any tax benefit. Alternatively, those costs could be added to the basis of the home if you didn't take the medical deduction, potentially reducing any taxable gain.

I just helped my dad sell his home and deal with all this last year. The magic word here is "basis" - you need to figure out the adjusted basis of the home. Start with what he paid originally ($35k), then add the cost of any major improvements over the years (new roof? kitchen remodel? addition?). Those all increase basis. Then when you subtract that final basis number from the sale price, that's the gain. Like someone mentioned, he probably qualifies for the $250k exclusion if it was his primary residence for 2 of last 5 years, so likely no tax. One important thing nobody mentioned - get all this documented NOW while you have access to records. Future you will thank you if this ever comes up in an audit or if you need to sell another property and need to reference precedent.

•What counts as a "major improvement" versus just regular maintenance? Like if he replaced the water heater, does that count?
