How to get Form 1098 for mortgage interest on co-owned house?
So I've got this complicated situation where I co-own a house with my ex-partner. The problem is he basically vanished about 8 months ago and moved overseas with his new girlfriend without telling anyone. It's been a complete nightmare trying to handle all the financial stuff on my own. I was talking to my tax accountant yesterday about filing for 2025, and she mentioned that I should use Form 1098 for reporting the mortgage interest and property taxes on the house. The thing is, I have no idea where to find this form or how to get it since all the mortgage stuff was set up in both our names. Has anyone dealt with this before? Can I just call the mortgage company directly to request it? Or is there a way to use my county property tax statement instead? My accountant wasn't super clear about alternatives, and I'm trying to get all my documents in order before the filing deadline. Any help would be appreciated!!

The Form 1098 is sent by your mortgage lender, not something you need to find or download. Your mortgage company should have mailed it to you already (they're required to send them by January 31st), or it might be available in your online mortgage account if you have one set up. If you haven't received it, you should definitely call your mortgage company directly. Explain the situation with your co-owner and ask them to send you a copy of the form. They'll have it on file and can usually email or mail you another copy pretty easily. As for using your property tax statement instead - that's not quite the same thing. The 1098 reports the mortgage interest you paid (which is potentially deductible) as well as property taxes paid through escrow. If you paid property taxes directly to the county (not through your mortgage), then yes, you would use those statements to claim that deduction, but you'd still want the 1098 for the mortgage interest portion.

•Thanks for the info! Quick question - if the 1098 was sent to my ex's address since that's what's on file with the mortgage company, can I still request a copy for myself even though I'm just a co-borrower? Do I need any special documentation to prove I'm entitled to it?

•As a co-borrower on the mortgage, you are absolutely entitled to receive a copy of the Form 1098. The mortgage company should be able to verify your identity using your Social Security number and other personal information they have on file. When you call, just explain that you're a co-owner on the property and need a copy of the 1098 for your tax filing. They deal with these situations all the time. If they give you any pushback (which is unlikely), you can mention that as a co-borrower who's paid interest on the loan, you have a legal right to the documentation for tax purposes.

I was in a really similar situation last year with a property I co-owned with my brother. Couldn't get the 1098 form anywhere and my mortgage company kept giving me the runaround. I finally used this service called taxr.ai (https://taxr.ai) that helped me sort everything out. They have this tool that analyzes your mortgage statements and tax documents and then tells you exactly what you can claim even without the 1098. Saved me hours of frustration and probably a bunch of money too. They were able to reconstruct all the information I needed for my tax filing from my bank statements showing the mortgage payments. The best part is they walked me through exactly how to report everything correctly on my return since I was filing without the actual form. Might be worth checking out if your mortgage company is being difficult.

•How does this taxr.ai service actually work? Do you just upload your mortgage statements and it figures everything out? I'm dealing with a similar issue but with a rental property where the management company is being super slow sending documents.

•Sounds interesting but I'm skeptical. How exactly can they "reconstruct" official tax information? Wouldn't the IRS require the actual 1098 form if you get audited? I'd be nervous about claiming mortgage interest without the proper documentation.

•You upload your mortgage statements, property tax records, and any other relevant documents, and their system uses AI to extract all the important information and organize it. It basically recreates what would be on your 1098 and shows you exactly what you can claim. The IRS actually doesn't require you to submit the 1098 with your return - they already get a copy directly from your lender. What matters is that the information you report matches what the lender reported. The taxr.ai service helps ensure your numbers are accurate based on the actual payments you made, which is what the IRS cares about during an audit.

I wanted to follow up about my experience with taxr.ai after I was skeptical in my earlier comment. I decided to give it a try when my mortgage company kept telling me my 1098 was "in the mail" for weeks. The service was actually incredibly helpful! I uploaded my monthly mortgage statements and property tax records, and it extracted all the interest and tax information perfectly. What really impressed me was that it caught that my mortgage company had made a calculation error on one of my statements that I would have just copied over. They even provided me with a detailed report I could keep with my tax records in case of an audit. Definitely worth it and saved me from having to keep calling my mortgage company every other day.

If calling your mortgage company doesn't work (and trust me, it can be IMPOSSIBLE to get through to them sometimes), you might want to try Claimyr (https://claimyr.com). I used them when I was in a similar situation trying to get tax forms from my lender. Basically they have this system that gets you through to a human at your mortgage company super fast instead of waiting on hold forever. I was literally on hold for 2+ hours before I gave up and tried their service. You can see how it works in this video: https://youtu.be/_kiP6q8DX5c With mortgage companies being so backed up right now, it saved me so much time. I got through to someone at my lender in about 10 minutes, explained my situation, and had them email me the 1098 form while I was still on the phone. Way better than the weeks of trying to call them myself.

•Wait, so how does this actually work? You pay a service to... call another company for you? Couldn't you just keep calling yourself? Not trying to be rude, just confused about what they actually do.

•This sounds like complete BS honestly. No way some random third party service has a "secret line" to mortgage companies. They're probably just calling the same customer service number you could call yourself. Total waste of money imho.

•They don't call for you - they use technology to navigate phone trees and hold systems to get you to a human representative faster. It's like having an express pass. You're still the one who talks to the representative. The reason it works is they've mapped out all the phone systems for major companies and know exactly which options to select and when to get through faster. They also have technology that keeps your place in line without you having to sit there listening to hold music. It's not a "secret line" - it's just a more efficient way to get through the regular customer service channels.

Alright, I need to eat my words from my previous comment. After my mortgage company left me on hold for literally 3 hours yesterday, I broke down and tried the Claimyr service that I was skeptical about. It actually worked exactly as advertised. I got a call back when a rep was available without having to stay on hold, and I was talking to someone from my mortgage company within about 15 minutes. The rep pulled up my 1098 information immediately and emailed me a copy while we were on the phone. Would I have eventually gotten through on my own? Probably. But after weeks of trying and failing, this saved me so much frustration. Sometimes it's worth paying a little to save yourself hours of aggravation.

Something nobody's mentioned yet - check if your mortgage company has an online portal! I never receive paper copies of my 1098 anymore because everything is electronic. Once I set up my online account, I could access all my tax forms, including current and past 1098s, by just logging in. Most of the big mortgage companies (Chase, Wells Fargo, Rocket, etc.) have this option, and even many smaller lenders do too. Look for a "Tax Documents" or "Tax Forms" section after you log in. Might save you a lot of hassle!

•I tried looking for an online portal but the mortgage is through a local credit union that has the most ancient website ever. I'm not even sure they have online account access beyond checking your balance. I'll give them a call tomorrow and see if they can email me the form. Thanks for the suggestion though!

Just want to add one important thing - if you're still sharing the mortgage with your ex even though he's gone, make sure you understand how the 1098 reporting works. The form usually only lists one borrower (primary) so if it has your ex's SSN on it, the IRS computer system is expecting him to report that interest. If you're claiming the interest on your return (which you probably should if you're making the payments), you need to include a statement with your tax return explaining that you're a co-borrower responsible for the debt and made the payments, but the 1098 was issued with the other person's info.

•Is this actually true? I thought mortgage interest could just be claimed by whoever pays it, regardless of whose name is on the 1098? My partner and I aren't married but split the mortgage and we both claim half the interest.

•The IRS rule is that the person who actually paid the interest can claim the deduction, regardless of whose name is on the form. However, the IRS computer system automatically matches 1098 forms to the SSN listed as the primary borrower. If you're not the primary borrower listed on the 1098 but you're claiming the deduction, you should include a statement explaining your situation to avoid a potential mismatch notice. This is especially important in cases like yours where you're claiming only a portion of what's on the 1098. The IRS publication actually states: "If you receive a Form 1098 which doesn't reflect the full amount of interest that you paid, you can still deduct the entire amount you paid. You'll just need to add a statement to your return explaining the difference.

I went through something very similar when my ex moved out suddenly and left me dealing with all the mortgage paperwork alone. Here's what worked for me: First, definitely call your mortgage company directly - as a co-borrower, you have every right to request the 1098. Have your SSN and loan number ready when you call. Most companies can email you a copy immediately once they verify your identity. If your mortgage company is being difficult or you can't get through, you have a few backup options: 1. Check if they have an online portal where you can download tax documents 2. If you paid through a bank account, your bank statements showing the mortgage payments can serve as backup documentation for the interest portion 3. For property taxes, if you paid them directly to the county (not through escrow), use those receipts One thing to be careful about - if the 1098 was issued with your ex's SSN as the primary borrower but you're claiming the deduction, include a brief statement with your return explaining that you're a co-borrower who made the payments. This helps avoid IRS matching issues later. The good news is that mortgage companies deal with these situations all the time, especially with divorces and separations. They should be able to help you get what you need for your tax filing.
