OBBBA's $400 Minimum QBI Deduction: How Very Small Businesses With Under $2,000 in Profit Beat the 20% Rate in 2026
For tax years starting in 2026, OBBBA makes the 20% qualified business income deduction permanent, widens the married-joint phase-in range to $394,600–$544,600, and adds a $400 minimum for taxpayers with more than $1,000 of QBI — so a $1,500 profit yields $400 instead of $300.
