Why The Mortgage Interest Deduction Isn’t As Helpful As You Think

November 13, 2017

THIS POST MAY CONTAIN AFFILIATE LINKS. PLEASE READ MY DISCLOSURE FOR MORE INFO.

 

Most people assume their home is a great investment.  I know I did when I bought my first home.  Through homeownership, you can build wealth and best of all, lower your taxes substantially through the mortgage interest tax deduction, right? 

 

Not necessarily.  In actuality, the mortgage interest tax deduction may be one of the most misunderstood tax deductions on the books today.  

 

A Little History

In 1913, interest deductions were first introduced into the tax code.  All interest, not just mortgage interest, was deductible on tax returns starting that year.  This included interest on personal loans such as credit card debt.  However, the deduction excluded the first $3,000 of income for singles and $4,000 of income for married couples.  Thus, the deduction affected less than 1% of the population at that time.  

 

A little over 30 years ago, the Tax Reform Act of 1986 limited the interest deductions to just mortgage interest.  The hope was that it would spur homeownership.  

 

Mortgage Interest Tax Deduction

The mortgage interest tax deduction allows taxpayers to deduct interest paid on their mortgage up to $1 million in principal on their home.  If your mortgage is $2 million, only the interest on the first $1 million of principal is tax-deductible.  In addition, you can also deduct the interest of up to $100,000 of home equity debt.

 

Most people qualify for the mortgage interest tax deduction as they don’t come anywhere near the $1 million principal limit.

 

Additionally, the interest deduction only applies to one’s first and second homes.  Thus there is no tax incentive to buy a third home.  However, this could change according to whatever tax plan is passed later this year.

 

More Limitations  

To qualify for a mortgage deduction, you must itemize your taxes when you file.  You would also need to forgo the standard deduction.  As of 2017, the standard deductions are: $6,350 for single people, $9,350 for “head of households”, and $12,700 for married couples filing jointly.  

 

In order for the mortgage interest deduction to help your tax situation, the deductions on your Schedule A must exceed the standard deduction.  Otherwise, you can only take the standard deduction and will not receive any additional tax benefit.

 

An Example

Let’s say you and your spouse paid $14,000 in mortgage interest on your home in 2017.  You would receive a $1,300 benefit over the standard deduction of $12,700.  If you are in the 20% tax bracket, you could only claim $260 in tax benefit.  

 

That hardly seems worth it if you paid $14,000 in mortgage interest.  

 

Average Savings of Mortgage Interest Deductions

The average savings in 2016 was $1,918.  However, those with incomes over $200,000 saved $4,149.  Meanwhile, the average American family, who earns less than $75,000 per year, saved less than $700.

 

Mortgage Interest Deduction
Returns in thousands, Money amounts in millions of dollars
Income Class Returns Amount
Below $10,000 6 $2
$10,000 to $20,000 138 $40
$20,000 to $30,000 350 $132
$30,000 to $40,000 668 $337
$40,000 to $50,000 1,153 $602
$50,000 to $75,000 4,692 $3,650
$75,000 to $100,000 5,074 $5,538
$100,000 to $200,000 14,597 $24,853
$200,000 and over 7,178 $29,782
Total 33,856 $64,936

As you can see, the real winners are those who earn $200,000 and over.  Although you may have heard that the mortgage interest tax deduction is a great benefit, it appears that it really only greatly benefits the wealthy.

 

Home Size & Homeownership

According to the Wall Street Journal, the average house size in the Washington, D.C area would be almost 1,400 square feet smaller if the mortgage interest tax deduction did not exist.  After all, the mortgage interest deduction was first enacted to promote home ownership.  

 

However, although the deduction has increased the size of housing, it has done very little to encourage people to buy homes.  In fact, US homeownership rates are similar to that of Canada and Australia, but neither Canada nor Australia offer mortgage tax deductions.

 

So, the next time someone tells you to obtain or keep your mortgage because of the wonderful tax benefits, you should take their advice with a grain of salt.

 

Readers, do you have a mortgage?  Do you itemize your taxes or go with a standard deduction?  Share your thoughts below.

    As a fairly high earner in a high income tax state the deduction from my homes interest and property taxes is significant. I’m getting anxious to potentially lose these deductions if the new proposed tax plan goes through. It will definetly hurt my savings rate.

    I don’t really think about our mortgage interest deductions. It does save us several thousand a year in taxes, yes, but I’m much more interested in the over $6000 we’d save in interest payments were we to pay it off. We have a fifteen year mortgage and have paid half off, so we’ll have less and less mortgage interest over the coming years as our payment on principal increases. I think most people miss the forest for the trees with this tax deduction, frankly. They justify taking out a 30-year mortgage and paying thousands more per year in interest for a rather small tax deduction. So I’m with you here!

      High earner here who has 5 years left on a 7 year ARM. I chose the mortgage type based on lowest rates and my ability to pay it off FAST. That said, I really appreciate the deduction and am sad to see it possibly going away. I think the real takeaway here is that FIRE principles are critical to people like me where someone else thinks I am “wealthy” but I don’t necessarily feel that way. I live by choice and force in expensive city and paid for an education that allowed me to get a high paying job. Each of these choices has brought more income, but at a higher up front cost. By slashing where I can and lobbying for tax treatment that benefits me, I can maintain my status as a high earner without it costing so much.

    Interesting article, many people I know who are younger in age use the investment line as the reason they buy their home.

    I don’t find anything wrong with buying a home at an early age if you are ready and your financial situation can afford it. Many people fail to see the maintenance cost, insurance cost, and the mortgage interest in their estimates of “investment.” The charts show another way they could miscalculate the benefit of having the house as well.

    Thanks for shring !

    Thanks for writing up the history of the mortgage interest deduction. And it’s very insightful how you compared household incomes versus how much in savings they get from the deduction.

    Personally, we itemize our deductions and have saved quite a bit in taxes over the last few years versus taking just the standard deduction.

    Definitely take the advice of it being a great deduction with a grain of salt. A person must analyze their own personal income and taxes to see if it’s worthwhile. Never make a home purchase because of the deduction!

    After my wife and I got married, we were able to pool resources and eliminate our mortgage on our small and modest house pretty quickly. I was never overly enticed by the mortgage deduction. For example, if you have to spend $3 in interest to save $1 on taxes, I thought it better just to save the $3 upfront and forget about the tax deduction. I know their is an opportunity cost on using one’s money this way, but I liked the sure thing. Tom

    As a high earner this is one of the only deductions we qualify for. Most everything else phases out. This is one of the reasons we don’t mind carrying a mortgage. If this disappears through tax reform, we will likely pay off the mortgage. For now, with the tax break and the interest rate so low, we’d rather keep the funds invested elsewhere.

    People have told me to not pay off the mortgage to take advantage of the tax benefits. But as Dave Ramsey said, you would have to pay $1,000 a year, for example, to get $300 back, which does’t make much sense.

    Mr. FAF and I are trying to pay off our mortgage. We’ve slowed down our progress a bit because we’re maxing out our 401(k) and saving for other future expenses. But I’m with you on this topic.

      It’s the opportunity cost that kills you though: a 200k mortgage at 4% over 30 years will cost ~$350k total. If you invest that 200k and get 7% return, you’ll get 1.3 million in gains which is still quite a lot more than the 100-150k you pay in net interest.

      Even at 5%, a delta of 1% over a 4% mortgage rate, you get $650k in gains on that $200k over 30 years. Take away 10% for tax, deduct the $150k you pay in interest, and you’re still up $435K. The mortgage interest benefit might improve this number a bit, but we don’t even really need to consider it.

      These numbers are when you have the cash to potentially pay off the house up front. However, the math is the math… the compounding over time of even a small difference in interest rate yields a large difference in gains regardless if the money is available on day 1 or day 5475 of the mortgage. These crazy low interest rates are a much bigger gift that any mortgage interest deduction will ever be.

      Of course, it only applies to folks who can save that money and leave it alone. That seems to be a small portion of the population overall, but hopefully most of us reading the blog. 🙂

    Yes I always heard about these mythical tax advantages of having a mortgage. They almost made it sound like you wanted a higher interest rate so you can deduct more. Then I got a mortgage but still filed a standard deduction.

    I bet a lot of people are filing a standard deduction and don’t even know it.

    It’s sad when you sit down and see how much you’re paying in interest VS the tax benefit. If I could I’d definitely pay off my mortgage in order to save all the money in interest. I’m thinking about taking a big chunk of the tax return this year and just applying it towards principal.

    In Canada, we don’t get to deduct the mortgage interest to lower our income tax on our principal home. However, there are a couple of methods that would allow us to deduct the mortgage interest.

    If we rent out part of our home, then a percentage of our mortgage interest can be deducted, but we will also have to report the rental income. If we buy an investment property, and we rent it out completely, then all the mortgage interest is deductible and there is no limit on the number of mortgages that you can deduct from.

    For our principal home, if we don’t rent it out, when we sell, we don’t have to pay capital gain tax on it. For rental properties, we’ll have to pay capital gain tax when we sell.

    For me personally, the real estate market had been a blessing as the home price in the area that I lived in more than doubled within the last ten years.

    I fall into AMT (Alternative Minimum Tax) and I’m so deep in the AMT that for me the entire mortgage interest expense is effectively deductible at a marginal rate of 35% federal (=28% rate times 1.25 due to phase-out of exemption) plus state tax. Over 40% combined! No constraint from the standard deduction! So, for me personally, the mortgage interest deduction is quite useful. Until next year when we (hopefully) get tax reform and get rid of the AMT. But that’s when I retire! 🙂

    We’re now at a point where it makes sense to itemize every other year (big property tax bill we can time 2x in same year), so the mortgage interest deduction really starts to lose its appeal. I’ll be interested to see what happens if the standard deduction goes up – housing may be hurt, but perhaps we should stop incenting home ownership anyway?

    Nice write up and a good look at the “other side” of the equation regarding mortgages. I for one will continue to pay down my mortgage at a faster pace. The tax savings are not what I am after, it’s the peace of mind of no longer having a payment. There are pros and cons to both side, it really is what you want to do.

    You touched on the biggest misconception I run across. People take their marginal tax rate times their mortgage interest payments to see the tax benefit. However, that ignores the standard deduction hurdle. $14,000 in mortgage interest x 20% = $2800 tax decrease. However, if they had no mortgage, they would still get the standard deduction of $12,700. $12,700 x 20% = $2540. The $14,000 mortgage interest payments yields a $260 incremental tax benefit or 260/14000 = 1.85% or stated otherwise every $100 of mortgage interest reduces your taxes by $1.85 compared to the standard deduction.

    This really depends where you live. Here in NY, it’s a big deal, esp when coupled w/ not being able to deduct real estate taxes and/or state taxes both of which are very high here.
    In my county, the median is $650,000 for a house and $800,000 for average. Sales tax is higher here vs most other states and in my county, you would gasp when you heard some of the real estate taxes.
    So, this whole tax thing is not a decrease, but rather an increase here…at least in it’s current state. I hope that they would make cost of living adjustments.

    As you mentioned, it all depends on your situation and can vary based on married vs single, etc. But, this has been a big deduction for me for the last 11 years. I did not realize about the cap of $100,000 home HELO. I had to do that to avoid jumbo loan rate.

    All that aside, of course you need to look at your interest rates, etc and your situation And, if you are in a situation to pay down the mortgage to avoid the interest, you could do so…but, it is still an opportunity cost of where you put your money. Sometimes it’s good to use OPM and have leverage while you invest elsewhere. And, diversification of assets is good too. To each their own. What good for one person isn’t necessarily good for another…or at different stages of their life.
