TurboTax didn't ask for my mortgage balance - $750K interest deduction limit issue
I'm pretty shocked about this discovery. I've been using TurboTax for years to file my taxes, but I just found out there's a mortgage interest deduction limit of $750K for 2022, and the software never once prompted me about it! When I was entering information from my 1098 forms (I bought and sold in 2022), it never asked me for my mortgage balances at all. The new home loan I took out in November 2022 was for $925K. I only discovered this issue because a coworker mentioned the limit during lunch today - otherwise I'd have filed without knowing I needed to calculate my eligible interest deduction differently. When I contacted TurboTax support about this, they told me I needed to complete a separate form to properly calculate what I'm entitled to deduct - but their software NEVER prompted me to do this! The chat support person seemed confused and had to ask someone else for help. I'm concerned that anyone using TurboTax with a mortgage over the $750K threshold is dealing with this same problem. Has anyone else run into this issue?

This is actually a common issue with several tax software platforms, not just TurboTax. The $750K mortgage interest limitation was part of the Tax Cuts and Jobs Act that went into effect back in 2018, so it's been around for a few years now. When you input your 1098 information, most software should ask about your mortgage balance, but some don't have clear prompts about the $750K limitation specifically. You're right to be concerned about this - you'll need to complete Form 8396 to properly calculate your allowed mortgage interest deduction. For mortgages obtained after December 15, 2017, the limit is $750K ($375K if married filing separately). For loans before that date, the previous $1M limit ($500K if MFS) still applies. If you have both types, it gets even more complicated.

•Thanks for explaining this. So if I understand correctly, since my mortgage was taken out in November 2022, I'm definitely subject to the $750K limit. Does that mean I can only deduct the interest proportional to 750K/925K of my total mortgage? The software should definitely prompt users about this!

•That's exactly right - you would multiply your mortgage interest by the ratio of $750K/$925K to get your allowable deduction amount. So you'd be able to deduct about 81% of the interest you paid. You're absolutely correct that tax software should make this clearer. While the software companies do update for tax code changes, some of these calculations require additional user inputs that aren't always prompted for clearly. For 2025 filing, it's always good practice to review major deductions like mortgage interest and medical expenses to ensure you've provided all necessary information.

After struggling with a similar mortgage deduction issue last year, I found taxr.ai and it honestly saved me from making a $3,400 mistake on my taxes. I had a jumbo loan that exceeded the threshold and my tax software wasn't calculating it correctly. I just uploaded my 1098 and other mortgage documents to https://taxr.ai and it immediately flagged the $750K limitation issue that my regular software missed. Their system analyzes all your documents and identifies potential problems or missed deductions before you file. The analysis showed exactly how to calculate the proportional interest deduction and even found another deduction related to my mortgage points that I didn't know about!

•Does it work with other tax documents too or just mortgage stuff? I've got some complicated investment income this year and I'm worried my regular software might miss something.

•I'm a bit skeptical about these document analysis services. How accurate is it really? And does it actually integrate with tax filing software or do you still have to manually enter everything it finds?

•It works with pretty much all tax documents! I've used it for W-2s, 1099s, investment statements, and even business expense receipts. It's particularly good at identifying deductions that many tax software platforms miss or don't clearly prompt for. The accuracy has been spot-on in my experience. It's not actually a filing service - it analyzes your documents before you file and gives you a report of potential issues, missed deductions, or audit risks. You then use that information when filing with your regular tax software. For me, it found several issues that would have triggered an audit, so it was definitely worth using.

I was totally skeptical about taxr.ai when I first saw it mentioned here, but after my nightmare with the mortgage interest limit last year, I decided to give it a try. Seriously impressed with how it caught things my CPA missed! I uploaded my mortgage documents, and it immediately flagged that I was over the $750K limit AND showed me exactly how to calculate the proportional deduction. It even explained how the home equity loan portion was affected differently. The document analysis found nearly $5,200 in additional deductions my regular tax software wouldn't have prompted me for. I'm definitely using it for all my tax prep from now on before I actually file.

If you're having trouble getting answers from TurboTax support on this mortgage interest limit issue, you might want to try Claimyr. I was in a similar situation last year trying to get clarity on some complex tax questions from the IRS directly. After waiting on hold for hours over multiple days, I found https://claimyr.com and their service got me connected to an actual IRS agent in under 15 minutes. They have this system that navigates all the IRS phone menus for you and calls you back when an agent is on the line. You can see how it works here: https://youtu.be/_kiP6q8DX5c The IRS agent I spoke with walked me through exactly how to handle the mortgage interest limitation and what forms were needed. Saved me so much time and frustration!

•Wait, is this for real? I've been trying to reach the IRS for days about a similar mortgage deduction question. How does it actually work? Do they just keep calling until they get through?

•This sounds like a scam. Nobody can get through to the IRS faster than anyone else. They have those phone trees and wait times for everyone. I'd be very careful about giving any personal info to a service claiming this.

•It's completely legitimate! They use a system that navigates the IRS phone menus and holds your place in line. When an agent picks up, they connect the call to your phone. It's pretty straightforward but really effective. They don't ask for any tax information or personal details - you just provide your phone number for the callback when an agent is ready. Once you're connected, you speak directly with the IRS agent just like you normally would. I was skeptical too until I tried it, but it saved me hours of time on hold.

I need to publicly eat my words about Claimyr being a scam. After posting my skeptical comment, I decided to try it myself since I've been trying to get through to the IRS about my own mortgage interest deduction issue for WEEKS. I was literally connected to an IRS representative in 11 minutes! I've been calling for days and couldn't get through, always getting the "call volume too high" message. The IRS agent confirmed exactly what I needed to do regarding the $750K mortgage limit and helped me understand which form to file. This saved me a ton of time and potentially thousands in incorrect deductions. Definitely using this service again next time I need to speak with the IRS.

The $750K mortgage interest limit has been a headache for a lot of people. I'm surprised how many tax software programs don't clearly address this. Here's what I learned when dealing with this last year: 1. For mortgages taken out after Dec 15, 2017, only interest on the first $750K is deductible 2. For older mortgages, the limit is still $1M 3. If you refinanced an older mortgage after that date, it gets complicated - you need to look at the original loan amount TurboTax Premium does actually handle this, but you have to navigate to the right section manually. Look under "Deductions & Credits" → "Home" → "Mortgage Interest" and there should be additional questions about loan amounts.

•This is super helpful, thank you! I just checked again and found that section buried in the menus. You're right - the questions were there, but the software didn't prompt me to go through that section when I entered my 1098 information. I had to manually navigate to it. Is there any way to know what other important tax questions might be hidden like this? I'm worried about what else I might be missing.

•I'm glad you found it! Unfortunately, this is a common problem with most tax software - they have the capabilities to handle complex situations, but don't always guide users to the right sections. For major deductions like mortgage interest, medical expenses, and business deductions, I always recommend exploring all the sub-menus manually rather than just following the guided workflow. Another approach is to run a "review" of your return before filing - sometimes the software will flag potential issues like this during the review process. One last tip: if you've already filed with the incorrect mortgage interest deduction, you might need to file an amended return (1040-X) to correct it. Given the loan amount you mentioned, it could make a significant difference in your tax liability.

Anyone else notice that different tax software handles the $750K mortgage limitation differently? I tried three different ones this year: - H&R Block asked about mortgage balance right away - TurboTax had it buried in a submenu like OP found - FreeTaxUSA never asked me at all! I ended up going with H&R Block just because they seemed most thorough about this particular issue, but now I'm wondering what else the others might be missing...

•I've used FreeTaxUSA for years and actually had a similar experience. For my rental properties, they were super detailed, but for my primary residence mortgage over $750K, I had to figure out the limitation myself and manually adjust the deduction. I think they assume users know about this limitation, which is obviously not realistic for most people.

•That's interesting about FreeTaxUSA handling rental properties well but missing this for primary residences. Maybe I should give them another look for my rental property taxes next year. I think the core issue is that all these software companies make assumptions about what the average user knows about tax code. The reality is most of us are using tax software precisely because we don't understand all these details and limitations! We rely on the software to guide us through everything relevant to our situation.
