The business interest expense deduction limitation — the infamous section 163(j) — was enacted as part of the Tax Cuts and Jobs Act (TCJA). In addition to being a major revenue-raiser, this provision is one of the most complicated sections of the tax reform law, but since the TCJA passed in late 2017, the Treasury Department and the IRS have been busy cranking out rules and guidance to help taxpayers implement the new law — and 2020 was no exception.
Here is where things stand as of early fall:
Coronavirus Aid, Relief, and Economic Security (CARES) Act changes
Prior to the CARES Act, the business interest expense deduction was limited to the sum of the taxpayer’s business interest income, plus 30% of adjusted taxable income (ATI), plus floor plan financing interest expense. The CARES Act added several special rules, which should be taken into account for 2020 tax planning, including:
- The Act retroactively increased the section 163(j) limitation to 50% of ATI (up from 30%) for 2019 and 2020, for taxpayers other than partnerships. Taxpayers have the option of electing out of this rule and using 30% instead of 50%.
- For partnerships, the increase to 50% only applies for 2020. Partners allocated excess business interest expense (EBIE) from 2019 can deduct 50% of that amount as an interest deduction in their 2020 tax year, without limitation.
- The Act also allows taxpayers to elect to use their 2019 ATI to calculate the 2020 section 163(j) limitation. This election will be helpful for taxpayers experiencing losses in 2020 due to current economic conditions.
Of course, no discussion of the CARES Act would be complete without mentioning qualified improvement property (QIP) and the interaction of the bonus depreciation rules with section 163(j). Taxpayers with real property trades or businesses can elect out of the business interest expense deduction limitation, but the trade-off is that they must use longer depreciation recovery periods for nonresidential real property, residential real property and QIP — and, under these rules, QIP would not be eligible for bonus depreciation. However, due to a drafting error in the TCJA, QIP was not eligible for bonus depreciation — this was known as the “retail glitch.” For many real estate taxpayers, since tenant improvements weren’t eligible for bonus anyway, this meant there was very little downside to making the election out of the interest limitation.
