When it comes to deducting interest on your tax return, where the money goes matters as much as where it came from.

That’s the lesson one Ascend client recently learned, and it’s a good reminder for anyone looking to refinance their home and redirect that cash into an investment. While it might seem more relevant to label it a home improvement loan to claim mortgage interest, that’s often not accurate.

Here, we explore how a $2 million loan, which was initially assumed to be mortgage-related, is instead qualified as investment interest. With expert guidance and a few savvy questions from Ascend’s Senior Manager Leslie Feyder, the client walked away with a much larger deduction and a smaller tax bill.

Let’s unpack the difference between mortgage interest and investment interest and how to avoid leaving money on the table.

Know the limits of mortgage interest deductions

Many taxpayers are familiar with the mortgage interest deduction and its association with the American Dream of homeownership. But what many people don’t realize is that this deduction is subject to tight restrictions, especially since changes introduced in the 2017 Tax Cuts and Jobs Act.

If the mortgage was secured after December 15, 2017, the deduction is limited to interest on up to $750,000 of qualified acquisition debt. That means if you refinance your home and take out more than that amount, even if it’s for home improvements, you can only deduct a portion of the interest.

In our client’s case, they refinanced and took out a $2 million loan. “They initially told me the money was for home improvements,” says Leslie. “That made sense to them because home improvements feel like they should fall under mortgage interest. But I noticed something else when reviewing their return.”

Always ask where the money goes

While their primary residence secured the client’s loan, Leslie spotted a large new capital contribution on one of their K-1 forms. “They had contributed $2 million into a new partnership. It matched the loan perfectly,” she recalls. “That’s when I realized that this wasn’t a home improvement loan. It was an investment loan.”

This distinction changed everything.

According to the IRS, mortgage interest is deductible only when the loan proceeds are used to buy, build, or substantially improve your primary or second home. If you use the money for any other purpose, such as investing in a partnership or purchasing stocks, it may qualify as investment interest instead.

Recognize when interest qualifies as an investment expense

Investment interest is basically what it says on the box: interest paid on money borrowed to purchase investments. The key rule, you can only deduct investment interest up to the amount of your net investment income.

This includes:

● Interest income

● Dividends

● Short-term capital gains

● And, with an election, even qualified dividends and long-term capital gains (though you’ll pay ordinary income tax rates on those if you make this election)

“Some people overlook investment interest because they don’t have enough investment income to make use of it,” explains Leslie. “But in this case, the client had a lot of interest income and dividends. So, we could take the entire interest deduction for this year.”

Calculate the real tax savings

Let’s look at the math.

If the $2 million loan had been treated as a mortgage loan, under federal rules, only $750,000 of that debt would have qualified for a deduction. That’s 37.5% of the total, meaning only 37.5% of the interest would be deductible. The rest? Gone forever.

However, by correctly categorizing the loan as investment interest, the client was able to deduct 100% of the interest, as their investment income was sufficiently high to support it.

“The savings came to $6,000,” says Leslie. “And that was just for a partial year. It was the first year of the loan. In future years, the deduction could be even more.”

Consider what happens without enough investment income

Here’s where investment interest becomes even more flexible.

If you don’t have enough investment income to deduct the full interest amount in a given year, you can carry the excess forward indefinitely. You don’t lose it.

That’s a big contrast to mortgage interest. “If you only qualify for a portion of the mortgage interest deduction, the rest is gone. You don’t get to use it in future years,” Leslie explains. “That’s why understanding your actual use of funds is critical.”

Avoid confusion over what secures the loan

One misconception is that the loan’s collateral determines how the interest is treated. Not true.

In this case, the $2 million loan was secured by the client’s home.  However, because the proceeds were used to invest in a commercial real estate partnership, the purpose of the loan qualified it for investment interest treatment.

“People often think that because the loan is on their house, it must be mortgage interest. But it’s not about what secures the loan. It’s about what the money is actually used for,” says Leslie.

Communicate clearly with your tax advisor

So why didn’t the client mention the investment upfront?

“They didn’t give me the full details during the return process,” says Leslie. “I just happened to notice that something didn’t quite line up, and I reached out to double-check. That one conversation made all the difference.”

Clients don’t always notify their tax advisor before making large investments. In this case, the client thought it would be better to treat the loan as mortgage related.

“When you communicate with your advisor before or during a big financial move, you give us a chance to guide you to the most beneficial outcome,” says Leslie.

Final thoughts: ask the right questions before you deduct

This case study is a prime example of why context is crucial in tax strategy.

A loan secured by your home doesn’t always equal mortgage interest. If you used the funds to invest in a business, real estate, or the stock market, you may qualify for investment interest treatment, which comes with both benefits and nuances.

Before claiming any deduction, ask yourself:

● Where did the money go?

● Do I have enough investment income to support an investment interest deduction?

● Should I elect to treat some capital gains or dividends as investment income?

● Did I inform my tax advisor of how I used the funds?

Tax season shouldn’t be a guessing game. The right answers, and strategy, can make a major difference.
