TCJA Changes to the Deduction for Mortgage Interest for 2018



How much mortgage interest can I deduct on my schedule A, itemized deductions, under the new tax law, the Tax Cuts and Jobs Act (TCJA)? That is a great question but the TCJA limits the loan size of which you can deduct interest on and not on the interest amount. I know, that is a challenge to wrap your mind around and it raises more questions.

Before we get to those questions we need to address the new standard deduction first as those question may be irrelevant now for many taxpayers.

Standard Deduction

Why is the new standard deduction relevant? Because it is now much higher and as a result a much higher percentage of taxpayers will be better off taking the standard deduction rather than itemizing. The new standard deductions for 2018:

Married Filing Joint and Surviving Spouse filers  $24,000
Head of Household  $18,000
Single and Married Filing Separately  $12,000

Additional Standard Deduction
Elderly (65 or over) or Blind MFJ  $1,300
If Unmarried  $1,600

Taxpayers need only be concerned about the limitations discussed below if their total itemized deductions could exceed their standard deduction. However, if your standard deduction is higher than your itemized deductions you may be still be able to deduct a portion of your mortgage interest if you are able to claim a home office deduction for your business.


Mortgage Interest Deduction Limits Under the TCJA

Loans Taken Out On or After December 17, 2017

For loans taken out on or after December 17, 2017 you are able to deduct interest on loans up to $750,000 of mortgage debt. For those filing Married Filing Separate the loan amount limit is $375,000. According to the IRS, "the limits apply to the combined amount of loans used to buy, build or substantially improve the taxpayer's main home and second home."

Whatif t he combined amount of loans used to buy, build or substantially improve the taxpayer's main home and second home exceeds the loan amount limit? According to an example given by the IRS, "a percentage of the total interest paid is deductible (see Publication 936). As of the time of writing this post, Publication 936 is not yet available for 2018.

The 2017 version of Publication 936 explained the calculation of deductible mortgage interest calculating it as a percentage of the total qualified home mortgage interest paid. So you were not able to take all of interest on the loan with a higher interest rate and a portion of interest from the loan with a lower interest rate.

Loans Taken Out Before December 17, 2017

The limits on loan amounts taken out before December 17, 2017 are $1,000,000 and $500,000 for those using the Married Filing Separate filing status.

Home Equity Loans and HELOCs

The new tax law did away with the mortgage interest deduction for Home Equity Loans and HELOCs unless they were used to improve your property. If you did take out one of these loans to improve your home the deductibility of this interest is still based on the limits discussed above.

Additionally, you will want to keep good records of the use of the proceeds from these loans to improve your home in case of an audit.

Bunching Itemized Deduction Strategy

To increase your itemized deductions and lower your taxes you could make extra payments in 2018 to increase your itemized deductions. You may be able to make your January mortgage payment early and deduct the portion of that payment which is for your interest for December of this year. In addition, if you are over the threshold for deductible medical expenses you could make those doctor visits before year end. Finally, you could also make extra charitable contributions before year end. Realize these strategies are best used if you are close to the standard deduction and use these strategies to take a higher itemized deduction in one year and take the standard deduction the following year. Otherwise with just itemized deductions you are taking a deduction this year that will lower your deductions the following year. Of course you probably want to lower this years taxable income as much as possible but not necessarily, it depends on what you expect next year to be like from a tax standpoint. It is best to discuss this strategy your "tax guy", and I would be happy to be your "tax guy".

You probably noticed that I left out state and local taxes. That is because starting in 2018 that part of your itemized deductions is capped at 10,000 a year. For now at least.

Be careful when reading about tax law and its application, including my articles, because the wording and definitions are such a challenge and are influenced by writers perspective, specifically his own clients situations that he is mindful of and other situations the writer is not thinking of. The point is talk to your CPA about your situation and circumstances and don't rely on or make conclusions based on articles you read, including articles form irs.gov, because concepts and definitions are not very clear, and of course, they are subject to change.
