Now that tax season is here, I’ve been having more conversations with people who are looking back at decisions they made during their divorce and wondering if they should have structured things differently.
One situation that comes up a lot involves using a home equity line of credit to buy out a former spouse.
Not because anyone did anything wrong — but because the focus during the divorce was on keeping a low interest rate first mortgage, and not necessarily on how the new loan would be treated at tax time.
When people sit down to prepare their taxes, that’s often when the question comes up:
Can I deduct the interest on the HELOC I used to buy out my ex?
Often the answer is not what they were hoping for.
Not all mortgage interest is deductible
Many homeowners assume that if a loan is secured by the house, the interest should be deductible.
Under current IRS rules, that is not always the case.
In general, interest on a home equity line of credit may only be deductible if the money was used to:
- buy the home
- build the home
- or make substantial improvements to the home
If the HELOC was used to pay out equity to a former spouse in a divorce, the interest may not qualify as deductible interest under current tax rules.
I’m not a CPA, but this is one of those areas where I know when to raise the flag and suggest that someone talk with their tax professional before the agreement is finalized.
Because once the loan is in place, the tax treatment usually can’t be changed.
Keeping the low rate sometimes becomes the only goal
During divorce, it’s very common for someone to want to keep their existing first mortgage, especially if the rate is much lower than what is available today.
To make that work, the solution is often to add a HELOC to pay out the other spouse.
On paper, that can look like the best option because it avoids refinancing the low-rate loan.
But sometimes the full math never gets run.
The higher-rate HELOC may not be deductible.
The payment may be higher than expected.
And the tax impact may not show up until the next filing season.
That’s when people start asking questions they wish had been asked earlier.
Comparing a HELOC to a buyout refinance should include the tax angle
In some cases, a buyout refinance comes with a higher interest rate, which makes people want to avoid it.
But depending on the situation, the tax treatment of the loan could be different.
That means the real cost of the loan isn’t just the rate — it may also include:
- whether the interest is deductible
- whether you can itemize
- how the loan affects taxable income
- and what the true monthly cash flow looks like after taxes
This is why it can be helpful to compare the options from every angle before the divorce agreement is final, not after.
Tax season is when these questions usually come up
I often see this issue surface months later, when someone is preparing their taxes and realizing that the structure they chose during the divorce may not have worked the way they expected.
Not because they did anything wrong.
But because they were focused on solving the immediate problem — keeping the house, keeping the rate, finishing the divorce — and didn’t realize how the loan might be treated later.
Divorce, taxes, and mortgage decisions are all connected, and looking at only the interest rate can sometimes lead to a decision that doesn’t work as well long-term.
I am not a tax advisor, and I don’t give tax advice.
But I do know when something needs a closer look, and HELOC interest used for a divorce buyout is one of those situations where it’s worth slowing down and running the numbers before the agreement is finalized.
If you are going through divorce and trying to decide how to handle the equity in the home, a mortgage planning review can help you compare refinance, HELOC, and buyout options from multiple angles before the settlement is signed.
