qualified_business_income floors each person’s income at zero before tax-unit aggregation. A 2022 joint return with $400,000 wages, $200,000 qualified SE profit and a $100,000 spouse qualified SE loss yields a $39,464.37 deduction instead of $19,464.37, assuming sufficient business W-2 wages and no suspended losses.
Form 8995-A Schedule C requires qualified losses to offset other QBI: https://www.irs.gov/pub/irs-prior/i8995a--2022.pdf#page=5
Preserve qualified losses through aggregation, including the interaction with separately modeled SSTB income and the QBI wage/property limit. Do not change partner test expectations just to absorb this change.
