Effective for tax years after 2025, the OBBBA created a new minimum deduction of $400 for taxpayers who have at least $1,000 of QBI from one or more active trades or businesses in which the taxpayer materially participates. An "active trade or business" for this provision means any qualified trade or business of the taxpayer in which the taxpayer "materially participates," as defined in Code Sec. 469(h).  Both the $400 and $1,000 are inflation adjusted to the nearest $5 after 2026.
