The proposed regulations also would provide additional guidance on the cross-reference to section 864(c) in the definition of qualified business income, the treatment of previously disallowed deductions or losses in the year of allowance, and additional aggregation examples. Finally, the proposed regulations would provide additional guidance on reporting requirements for relevant passthrough entities and publicly traded partnerships, and additional guidance for computing the deduction under section 199A for electing small business trusts.
