As you likely know by now, the Tax Cuts and Jobs Act (TCJA) reduced or eliminated many deductions for individuals. One itemized deduction the TCJA kept intact is for investment interest expense. This is interest on debt used to buy assets held for investment, such as margin debt used to buy securities. But if you have investment interest expense, you can’t count on benefiting from the deduction.

3 hurdles

There are a few hurdles you must pass to benefit from the investment interest deduction even if you have investment interest expense:

1. You must itemize deductions. In the past this might not have been a hurdle, because you may have typically had enough itemized deductions to easily exceed the standard deduction. But the TCJA nearly doubled the standard deduction, to $24,000 (married couples filing jointly), $18,000 (heads of households) and $12,000 (singles and married couples filing separately) for 2018. Plus, some of your other itemized deductions, such as your state and local tax deduction, might be smaller on your 2018 return because of TCJA changes. So you might not have enough itemized deductions to exceed your standard deduction and benefit from itemizing.
2. You can’t have incurred the interest to produce tax-exempt income. For example, if you borrow money to invest in municipal bonds, which are exempt from federal income tax, you can’t deduct the interest.
3. You must have sufficient “net investment income.” The investment interest deduction is limited to your net investment income. For the purposes of this deduction, net investment income generally includes taxable interest, nonqualified dividends and net short-term capital gains, reduced by other investment expenses. In other words, long-term capital gains and qualified dividends aren’t included. However, any disallowed interest is carried forward. You can then deduct the disallowed interest in a later year if you have excess net investment income.

You may elect to treat net long-term capital gains or qualified dividends as investment income in order to deduct more of your investment interest. But if you do, that portion of the long-term capital gain or dividend will be taxed at ordinary-income rates.

Will interest expense save you tax?

As you can see, the answer to the question depends on multiple factors. We can review your situation and help you determine whether you can benefit from the investment interest expense deduction on your 2018 tax return.

While the Tax Cuts and Jobs Act (TCJA) generally reduced individual tax rates for 2018 through 2025, some taxpayers could see their taxes go up due to reductions or eliminations of certain tax breaks — and, in some cases, due to their filing status. But some may see additional tax savings due to their filing status.

Unmarried vs. married taxpayers

In an effort to further eliminate the marriage “penalty,” the TCJA made changes to some of the middle tax brackets. As a result, some single and head of household filers could be pushed into higher tax brackets more quickly than pre-TCJA. For example, the beginning of the 32% bracket for singles for 2018 is $157,501, whereas it was $191,651 for 2017 (though the rate was 33%). For heads of households, the beginning of this bracket has decreased even more significantly, to $157,501 for 2018 from $212,501 for 2017.

Married taxpayers, on the other hand, won’t be pushed into some middle brackets until much higher income levels for 2018 through 2025. For example, the beginning of the 32% bracket for joint filers for 2018 is $315,001, whereas it was $233,351 for 2017 (again, the rate was 33% then).

2018 filing and 2019 brackets

Because there are so many variables, it will be hard to tell exactly how specific taxpayers will be affected by TCJA changes, including changes to the brackets, until they file their 2018 tax returns. In the meantime, it’s a good idea to begin to look at 2019. As before the TCJA, the tax brackets are adjusted annually for inflation.

Below is a look at the 2019 brackets under the TCJA. Contact us for help assessing what your tax rate likely will be for 2019 — and for help filing your 2018 tax return.

While most provisions of the Tax Cuts and Jobs Act (TCJA) went into effect in 2018 and either apply through 2025 or are permanent, there are two major changes under the act for 2019. Here’s a closer look.

1. Medical expense deduction threshold

With rising health care costs, claiming whatever tax breaks related to health care that you can is more important than ever. But there’s a threshold for deducting medical expenses that was already difficult for many taxpayers to meet, and it may be even harder to meet this year.

The TCJA temporarily reduced the threshold from 10% of adjusted gross income (AGI) to 7.5% of AGI. Unfortunately, the reduction applies only to 2017 and 2018. So for 2019, the threshold returns to 10% — unless legislation is signed into law extending the 7.5% threshold. Only qualified, unreimbursed expenses exceeding the threshold can be deducted.

Also, keep in mind that you have to itemize deductions to deduct medical expenses. Itemizing saves tax only if your total itemized deductions exceed your standard deduction. And with the TCJA’s near doubling of the standard deduction for 2018 through 2025, many taxpayers who’ve typically itemized may no longer benefit from itemizing.

2. Tax treatment of alimony

Alimony has generally been deductible by the ex-spouse paying it and included in the taxable income of the ex-spouse receiving it. Child support, on the other hand, hasn’t been deductible by the payer or taxable income to the recipient.

Under the TCJA, for divorce agreements executed (or, in some cases, modified) after December 31, 2018, alimony payments won’t be deductible — and will be excluded from the recipient’s taxable income. So, essentially, alimony will be treated the same way as child support.

Because the recipient ex-spouse would typically pay income taxes at a rate lower than that of the paying ex-spouse, the overall tax bite will likely be larger under this new tax treatment. This change is permanent.

TCJA impact on 2018 and 2019

Technology has made it easier to work from home so lots of people now commute each morning to an office down the hall. However, just because you have a home office space doesn’t mean you can deduct expenses associated with it.

Regularly and exclusively

In order to be deductible for 2019 and 2020, you must be self-employed and the space must be used regularly (not just occasionally) and exclusively for business purposes. If, for example, your home office is also a guest bedroom or your children do their homework there, you can’t deduct the expenses associated with the space.

Two options

If you qualify, the home office deduction can be a valuable tax break. There are two options for the deduction:

• Write off a portion of your mortgage interest, property taxes, insurance, utilities and certain other expenses, as well as the depreciation allocable to the office space. This requires calculating, allocating and substantiating actual expenses.
• Take the “safe harbor” deduction. Only one simple calculation is necessary: $5 times the number of square feet of the office space. The safe harbor deduction is capped at $1,500 per year, based on a maximum of 300 square feet.

Changes through 2025

Under prior tax law, if you were an employee (as opposed to self-employed), you could deduct unreimbursed home office expenses as employee business expenses, subject to a floor of 2% of adjusted gross income (AGI) for all your miscellaneous expenses. To qualify under prior law, a home office had to be used for the “convenience” of your employer.

Unfortunately, the TCJA suspends the deduction for miscellaneous expenses through 2025. Without further action from Congress, employees won’t be able to benefit from this tax break for a while. However, deductions are still often available to self-employed taxpayers.

If, however, you’re self-employed, you can deduct eligible home office expenses against your self-employment income. Therefore, the deduction will still be available to you through 2025.
