The CARES Act increases the 30% of adjusted taxable income (ATI) limit on the business interest deduction (as imposed under the 2017 tax reform law) to 50% for corporations in 2019 and 2020. All entities (corporations and pass-throughs) can elect to use 2019 ATI instead of 2020 ATI in determining the 2020 business interest expense deduction, which could increase the business interest deduction for businesses who are likely to see reduced income levels in 2020.
