Since proposed regulations were not issued for owner/beneficiary information relating to the 20% of qualified business income deduction until August 8, 2018 and it wasn’t listed on the 2017 forms, that information was omitted on many passthrough entity income tax returns for fiscal years ending in 2018. According to proposed regulations issued on August 8, 2018, that information should be included on the 2018 income tax returns for the owner. (Proposed Regulations Sections 1.199A-1(f)(2) and 1.643(e)-(2)(ii).) If that information is listed on the owner’s Schedule K-1, it’s presumed to be zero. (Proposed Regulations Section 1.199A-6(b)(3)(iii).)
