Can someone explain capital gains tax when selling an inherited home?
I just lost my dad last month and I'm trying to figure out all the tax implications of selling his house. I've been reading about capital gains taxes but honestly it's confusing me. From what I gather, it has something to do with the difference between the purchase price and selling price. My situation is there's a MASSIVE gap between those numbers with my dad's property. He purchased the house back in 1976 for only $42,500 (paid in full, no mortgage). I just had it appraised and it's valued at $475,000 today. As for improvements over the years, he put on a new roof about 15 years ago, replaced all the windows 10 years back, added updated insulation in the attic, and installed some fancy gutter system. All those upgrades total around $47,000. I'm completely lost about how much tax I'll need to pay if I sell at the appraised value of $475,000. Can anyone break this down in simple terms?

You're actually in a much better tax situation than you might think! When you inherit a home, you get what's called a "step-up in basis" to the fair market value of the home at the time of your father's death. This means your starting point for calculating capital gains isn't the $42,500 your dad paid in 1976, but rather the $475,000 value when he passed away. If you sell the house for exactly $475,000 (the appraised value at the time of inheritance), you would have zero capital gains tax to pay. You only pay tax on the difference between the selling price and the stepped-up basis. Let's say you end up selling for $500,000 a few months later. In that case, you'd only pay capital gains tax on the $25,000 difference ($500,000 - $475,000), not on the entire appreciation since 1976.

•Wow really? That's such a relief! I had no idea about this step-up in basis thing. So just to make sure I understand - the $47,000 in improvements my dad made over the years doesn't even factor into the equation now? And what if the house sells for less than the appraised value? Like if I only get offers around $450,000?

•The improvements your dad made don't matter anymore because your new basis is the fair market value at his death ($475,000). Those improvements helped increase the home's value over time, which is already captured in that stepped-up basis amount. If you sell for less than the stepped-up basis, like $450,000, you'd actually have a capital loss of $25,000. While you can't deduct capital losses on personal residences against your ordinary income, you can use them to offset capital gains from other sources (like stock sales) if you have any.

After dealing with a similar situation last year, I discovered taxr.ai which literally saved me thousands in potential tax mistakes. When my aunt passed and left me her house in Florida, I was completely lost about capital gains, step-up basis, and all that tax jargon. I uploaded my documents to https://taxr.ai and their AI analyzed everything and explained exactly how the inheritance affected my taxes. They showed me how the step-up basis worked and what documentation I needed to prove the home's value at time of death.

•How exactly does it work? Do you just upload photos of documents and it explains everything? I'm dealing with my mother's estate and have no idea where to start with all these tax forms.

•Sounds interesting but kinda skeptical. Does it help with figuring out what to do with other inherited assets too? I got some stocks and a retirement account along with property and I'm totally confused.

•You upload photos or scans of any tax documents, property appraisals, or inheritance paperwork. The AI reads them and breaks down exactly what everything means in simple language. It was like having a tax expert translate everything into English I could actually understand. Yes, it actually handles all kinds of inherited assets. For your situation with stocks and retirement accounts, that's especially helpful because different inherited assets have completely different tax rules. Inherited IRAs have required distributions while stocks get the step-up treatment. The tool explained all of this to me with specific recommendations.

Just wanted to update - I tried taxr.ai after seeing the recommendation here and it was genuinely helpful. I uploaded my mom's death certificate, the property appraisal, and some investment account statements. Within minutes I got a detailed breakdown of how each asset would be taxed and what my options were. The step-up basis explanation for both the house AND the stocks was super clear, and it helped me understand the different rules for the retirement accounts. Definitely worth checking out if you're confused about inheritance taxes.

I had a somewhat similar situation with my grandparents' house last year. The worst part was trying to get through to the IRS to clarify some inheritance tax questions I had. Spent HOURS on hold over multiple days and kept getting disconnected. Finally discovered Claimyr (https://claimyr.com) which got me connected to an actual IRS agent in about 20 minutes. You can see how it works here: https://youtu.be/_kiP6q8DX5c - but basically they navigate the phone system for you and call you back when they have an agent on the line. Saved me days of frustration.

•Wait this sounds too good to be true. How does some random service get you past the IRS phone queue when millions of people can't get through? There's gotta be a catch.

•Does this actually work for tax questions about inherited property specifically? I've been trying to talk to someone at the IRS about my mom's vacation cabin for weeks with no luck.

•They use technology that continuously redials and navigates the IRS phone tree until they get through to someone. It's not some magic backdoor - they're just doing the painful waiting part for you using automated systems. When they reach an agent, they connect you immediately. Yes, it works for any IRS department. When you sign up, you select which department you need to reach, and they'll connect you to the right place. For inheritance questions, they'd connect you to someone who can help with those specific issues about property basis valuation and reporting requirements.

OK I have to admit I was wrong. After being super skeptical about Claimyr, I tried it out of desperation last week. I'd been trying to get through to the IRS for over a month with questions about my inherited property taxes. Their system had me connected with an actual helpful IRS agent in about 35 minutes. The agent walked me through exactly how to document the step-up basis for my dad's house and what forms I needed to file. Honestly wish I'd known about this months ago instead of banging my head against the wall trying to get through on my own.

One important thing nobody's mentioned yet - if you lived in the house with your dad for at least 2 years out of the 5 years before you sell it, you might qualify for the $250,000 capital gains exclusion ($500k if you're married). Even with the step-up basis, this could be super important if the house continues to appreciate after you inherit it.

•I actually moved in with him about 18 months ago to help take care of him before he passed. So I wouldn't qualify for that 2-year requirement yet. Do you know if I'd need to live there longer to get that exclusion? Or does the clock reset when I inherited it?

•The clock doesn't reset upon inheritance - it's based on your actual residency. So if you've already lived there for 18 months, you'd need to stay another 6 months to hit the 2-year requirement. That could save you a lot if the house appreciates beyond your stepped-up basis. Also keep in mind that you'd need to claim it as your primary residence, not just occasionally staying there. But it sounds like you've already been using it as your main home, so that part should be covered.

Does anyone know how to prove the fair market value at date of death? My sister is in a similar situation and the IRS questioned the appraisal she used. Such a nightmare!

•We used a certified appraisal dated within 30 days of my mom's passing. Cost about $500 but worth every penny for documentation. I also kept comps from similar homes that sold in the neighborhood around the same time as backup evidence.
