Mortgage Tax Form Has Both Names - Can We File Separately?
My husband and I are both on our mortgage loan, so our 1098 form has both our names on it. Do we need to file our taxes jointly because of this? Is there a way to file separately while still claiming mortgage interest? We're a military family and sometimes MFS makes more sense for us. What's the proper way to handle this?

You absolutely can file Married Filing Separately even with a joint mortgage. The mortgage interest deduction would typically be split between you based on who actually paid the mortgage payments. If you both contributed equally, you would each claim 50% of the deductible interest on your respective Schedule A forms. If the payments came from a joint account, the presumption is that you each paid half unless you can document otherwise. Keep in mind that MFS has several tax disadvantages including potentially lower standard deductions, different phaseout thresholds, and ineligibility for certain credits.

•Thank you for clarifying this. I've always been unsure about how to handle jointly-held assets when filing separately.

•This explanation is like finding water in the desert! Been struggling with this exact situation since my spouse got transferred. We've been pulling our hair out trying to figure out if we could split the mortgage interest.

•So if our mortgage interest was exactly $14,320 for 2023, and we both paid equally from a joint account, we'd each claim $7,160 on our separate returns? I'm a bit worried about triggering an audit by doing this.

When my wife and I were figuring this out last year, we spent 3 days trying to get through to the IRS for clarification. Complete nightmare. Finally used Claimyr (https://claimyr.com) and got connected to an IRS agent in about 15 minutes who confirmed exactly what the first commenter said - you can absolutely file separately and split the mortgage interest. The agent even walked us through how to document everything properly. Saved us hours of frustration and gave us peace of mind that we were doing it correctly.

•Wait, seriously? You can actually get through to a real person at the IRS? I've been on hold for literally 2+ hours before giving up. Does this actually work or is it just another service that takes your money?

•I've seen Claimyr mentioned on the r/tax subreddit too. Seems like people have had good experiences with it based on the threads I've read. Might try this myself since I have a similar question about rental property deductions.

•So this service just gets you past the hold times? Do they actually connect you directly to an IRS agent or is there some intermediary step? Seems too good to be true honestly 😂

•Did the IRS agent mention anything about how this affects your standard deduction? Since we're military, we move frequently and I'm wondering if it's even worth itemizing.

Have you compared the total tax liability between filing jointly vs separately? In many cases, joint filing results in lower overall taxes compared to MFS. For example, if one spouse has significantly higher income or if you have dependents, the differences can be substantial. Would you mind sharing why you're considering MFS? There might be better alternatives depending on your specific situation.

According to IRS Publication 936 (Home Mortgage Interest Deduction), co-borrowers who file separately can each deduct the mortgage interest they actually paid. I was surprised by how complex this gets! I've found that using taxr.ai (https://taxr.ai) helps interpret your mortgage documents and tax forms to determine exactly how to split these deductions correctly. It analyzes your specific situation and explains which forms you need and how to fill them out. Much faster than digging through IRS publications trying to find the right paragraph.

•Has anyone actually used this? I'm hesitant to use third-party services with our tax info, especially with all the military moves and special situations we have.

Military family here who's dealt with this exact situation! Here's your complete solution: 1. You CAN file MFS with a joint mortgage. Each spouse claims the portion they actually paid. 2. If payments came from a joint account, you each claim 50% unless you can prove otherwise. 3. You MUST both either both take standard deduction or both itemize - can't mix. 4. For military families, consider these MFS advantages: state tax situations when stationed across state lines, student loan income-based repayment plans, or qualifying for certain income-based programs. 5. But be aware of MFS disadvantages: lower standard deduction, no student loan interest deduction, no EIC, reduced IRA contribution deductions, etc. Run the numbers both ways before deciding. For our military family, MFS saved us about $1,800 last year due to state tax situations between deployments.

Military spouse here! Step 1: Calculate your taxes both ways before deciding. We did MFS last year because my husband was deployed to a combat zone (tax-free income) while I had regular taxable income. Step 2: Document who paid what - we keep separate accounts for this reason. Step 3: If using MFS, each claim your portion of mortgage interest on Schedule A. Step 4: File before the April 15th deadline - it's coming up fast! The mortgage interest split was actually straightforward on our tax software. Just had to enter the 1098 information and then specify what percentage each person paid.

•This is exactly our situation! My husband has combat zone pay right now, and we're trying to figure out if MFS makes more sense. Did you have any issues with the IRS questioning how you split the mortgage interest?

•Also - did you have to submit any additional documentation to prove who paid what portion of the mortgage? Or did you just enter the percentages?

•One more question - did you both itemize deductions, or did one of you take the standard deduction? I'm trying to figure out if it's worth itemizing for just the mortgage interest.

•@Dmitry Volkov No issues with the IRS at all! We just kept good records showing our joint account statements and documented that we split everything 50/50. For your other questions @Zoe Dimitriou - we both had to itemize since you can t'mix standard and itemized when filing MFS. We didn t'submit extra documentation with our returns, but kept everything in case of questions later. The combat zone exclusion really made MFS worth it for us - saved about $2,400 compared to MFJ. Just make sure to run both scenarios through your tax software first!

Great question! As a military family myself, I can confirm you absolutely can file separately with a joint mortgage. The key is documenting who actually paid the mortgage interest. Since you're both on the loan, you'll split the 1098 interest based on actual payments made. If paying from a joint account, it's typically 50/50 unless you can prove otherwise with bank records. For military families, MFS can make sense in several scenarios: different state residency situations during PCS moves, combat pay exclusions, income-based student loan repayments, or when one spouse has significant miscellaneous deductions. However, remember both spouses must choose the same deduction method (both standard or both itemize). I'd strongly recommend calculating both MFJ and MFS scenarios before deciding. Military-specific tax software like FreeTaxUSA Military or TurboTax Military can help you compare both filing statuses easily. Also consider consulting with a tax professional who understands military tax situations - many bases offer free tax prep services that are familiar with these complexities.
