Mortgage Interest Deduction for a fully paid home? Am I missing something?
So my wife and I fully paid off our house about 2 years ago (yay us!) but I keep hearing friends and coworkers talk about how they "need" their mortgage for the tax deduction. They act like I'm throwing away free money by not having a mortgage payment anymore. I understand the mortgage interest deduction is a thing, but am I actually financially worse off by NOT having a mortgage? Like, wouldn't I be paying way more in interest than I'd get back in tax savings? I'm trying to understand if I'm missing something major here or if people just repeat this "need the mortgage deduction" thing without actually doing the math. We're in the 24% tax bracket if that matters. Our home is worth about $425k now. Sometimes I wonder if we should take out a HELOC or something just for the tax benefits, but that feels like borrowing money just to get a small percentage back? Am I crazy for questioning this conventional wisdom?

You're definitely not crazy - in fact, your instinct is spot on! The mortgage interest deduction is widely misunderstood. Here's the simple truth: paying $10,000 in mortgage interest to save maybe $2,400 in taxes (at your 24% bracket) means you're still out $7,600 compared to having no mortgage. Think of it this way - would you give someone $100 if they promised to give you $24 back? That's essentially what people are doing when they "keep a mortgage for the deduction." The only time mortgage debt makes financial sense is when you're using that borrowed money to invest in something with a higher return than the interest rate you're paying, not for tax benefits. Congratulations on paying off your home - you're in a financially advantageous position that many only dream of achieving!

•But what about using the mortgage deduction to itemize? I've heard that without it, many people just take the standard deduction instead, which is leaving money on the table. Doesn't that factor in?

•That's a great question about itemizing! With the standard deduction now at $27,700 for married filing jointly (2025), many people don't have enough deductions to itemize anyway. Without a mortgage, you'd need over $27,700 in other itemized deductions (state/local taxes, charitable donations, etc.) to benefit from itemizing. For most people, even with a mortgage, the standard deduction is still higher than their potential itemized deductions. So you're not leaving money on the table - you're actually avoiding unnecessary interest payments while still getting the full standard deduction benefit.

After struggling to understand my own tax situation with a mortgage, I found this amazing AI tool called taxr.ai that helped me analyze this exact question. I was also told I "needed" my mortgage for tax purposes, but when I uploaded my documents to https://taxr.ai it showed me a side-by-side comparison of what I'd save with/without the mortgage - turned out I was paying $14k in interest to save about $3k in taxes. Not a great deal! The tool can analyze your specific situation based on your income, deductions, and tax bracket to show if mortgage interest is actually beneficial. It also helped me understand how the standard deduction impacts this whole equation. Their tax planning feature was eye-opening.

•How accurate is this tool? Does it take into account state taxes too? I'm in California where we have high state income tax so I'm wondering if that changes the math on mortgage deductions.

•I'm kinda skeptical of online tax tools... like how does it know if I should itemize or not? I tried using TurboTax for this and got confused. Does this thing actually explain why a mortgage deduction might not be worth it in simple terms?

•Yes, it absolutely takes state taxes into account! I'm in a high-tax state too (New York), and it factored in both my state income tax and property taxes when calculating whether the mortgage interest deduction made sense. It even showed how close I was to the SALT cap. It's way more straightforward than TurboTax for this specific question. It doesn't just calculate - it explains the logic in plain English with personalized examples. What I found most helpful was how it showed exactly how much additional itemized deductions I would need to make itemizing worthwhile without a mortgage. The visualization made it super clear why following the "keep your mortgage for taxes" advice was costing me money.

Wow, I just tried out that taxr.ai site and it was eye-opening! I've been hanging onto my mortgage because my brother-in-law (who thinks he's a financial guru) kept telling me I needed it for tax purposes. The analysis showed me that in my specific situation, I was paying about $9,600 in interest annually to save only $2,112 in taxes! The tool broke down exactly how much additional deductions I'd need to itemize without a mortgage, and showed that with my charitable contributions and state taxes, I was actually still better off taking the standard deduction anyway. Now I'm considering making extra payments to pay down the mortgage faster instead of listening to my brother-in-law. Thanks for sharing this resource!

I spent 3 WEEKS trying to get through to an IRS agent to ask about this exact mortgage deduction question (my tax situation is complicated with rental properties too). After endless busy signals and disconnections, I found Claimyr https://claimyr.com and watched their demo at https://youtu.be/_kiP6q8DX5c - they actually got me connected to an IRS agent in about 20 minutes! The agent confirmed what others are saying here - keeping a mortgage just for tax purposes doesn't make financial sense in most cases. They walked me through my specific numbers and showed that with the higher standard deduction, my rental property deductions, and charitable giving, the mortgage interest on my primary residence wasn't providing the tax benefit I thought it was.

•Wait how does this service actually work? Does it just call the IRS for you? Couldn't you just keep calling yourself and eventually get through?

•Yeah right, no way this actually works. The IRS phone lines are completely jammed and have been for years. I've tried calling dozens of times and never got through. How could some random service magically get you connected? Sounds like snake oil to me.

•It doesn't just call for you - it uses some kind of system that navigates the IRS phone tree and holds your place in line. When an agent is about to pick up, it calls your phone and connects you directly to the agent. So instead of you being on hold for hours, their system does the waiting. I was super skeptical too! I had already spent about 15 hours over three weeks trying to get through myself. I would set aside big chunks of time, call repeatedly, and kept getting busy signals or disconnected after waiting on hold. The IRS wait times this tax season are insane - I read they're only answering like 1 in 10 calls. With Claimyr, I just entered my number, they called me back when an agent was available, and I actually got my questions answered. Definitely not snake oil - it saved me from pulling my hair out!

I have to eat my words here. After my skeptical comment, I decided to try that Claimyr service since I've been trying unsuccessfully to reach the IRS about a similar mortgage deduction question for my mom's estate. It actually worked! Got connected to an agent in about 35 minutes (they sent text updates about my place in line). The IRS agent was really helpful and explained that the whole "keep your mortgage for the tax deduction" advice is outdated, especially after the tax changes and increased standard deduction. For most people, the math just doesn't work out anymore. She confirmed that paying off a mortgage and avoiding interest is usually the better financial move. Saved me from giving my mom's executor some bad advice!

People repeating "keep your mortgage for the tax deduction" are basically just parroting outdated advice from the 1980s-90s when: 1. Interest rates were WAY higher (remember 12-18% mortgages?) 2. The standard deduction was much lower 3. Tax brackets were different Today's math is totally different. If you're paying 6% interest on a mortgage, you're paying $6,000 per year on every $100k borrowed. Even in the 37% tax bracket (highest possible), you'd save $2,220 in taxes while spending $6,000. That's a guaranteed loss of $3,780! Being mortgage-free is financial freedom. Congrats on paying it off and don't second-guess yourself!

•Does this calculation change if you have other substantial deductions already? Like if I'm already itemizing because of large charitable contributions and state taxes?

•If you're already itemizing due to other substantial deductions, then the mortgage interest would provide some additional tax benefit, but the math still typically doesn't favor keeping a mortgage just for tax purposes. Let's say you already have $25,000 in itemized deductions from charitable giving and state taxes. Adding $10,000 in mortgage interest would increase your itemized deductions to $35,000, which is $7,300 more than the standard deduction for married filing jointly. At your 24% tax bracket, that additional $7,300 in deductions would save you about $1,752 in taxes. But you're still paying $10,000 in interest to get that $1,752 benefit - a net loss of $8,248. The mortgage is still costing you significantly more than you're saving in taxes.

I'm an accountant (not giving official tax advice here!) and I cringe every time I hear the "need mortgage for taxes" thing. Let's break it down super simple: Standard deduction for married 2025: $27,700 To itemize, ALL your deductions combined need to exceed this amount Deductions might include: - Mortgage interest - State/local taxes (capped at $10k) - Charitable giving - Medical expenses (only amount > 7.5% of AGI) Most people simply won't exceed $27,700 in combined deductions, making the mortgage interest irrelevant for tax purposes. You're actually financially AHEAD by NOT having a mortgage!

•This makes so much sense when you explain it that way. My parents have always told me never to pay off the mortgage early because of taxes, but they bought their house in the 70s when everything was different! Thank u for clearing this up!

•Another accountant here - can confirm this is 100% correct. I see this misconception ALL THE TIME with clients. Being debt-free is almost always better than paying interest for a partial tax deduction. The only exception might be if you're investing the difference at a higher return, but that's a risk/reward discussion, not a tax one.
