The $400 You're Owed: The New Minimum QBI Deduction

The qualified business income (QBI) deduction is staying at 20% for 2026 — and the real news is better than a rate change. It's now permanent, the income ranges where the deduction phases out got wider, and business owners now have a $400 minimum deduction to count on. Here's what that means in practice, and why it's worth a conversation with your advisor this fall.

What Actually Changed

Three things changed, all effective 2026. First, the 20% deduction is now permanent. It used to be scheduled to disappear after 2025, so every decision about how a business was structured had to hedge against that. That uncertainty is gone. Second, the income ranges where the deduction starts shrinking got wider — for single filers, from $50,000 up to $75,000; for joint filers, from $100,000 up to $150,000. Third, there's a new floor: if you have at least $1,000 of qualifying business income and you're actively involved in running that business, your deduction is now at least $400, and that floor will adjust upward each year for inflation.

Who the $400 Floor Helps

On its own, $400 doesn't sound like much — most established businesses clear that easily without the floor. It matters most for newer or smaller operations. As an illustrative example only: a side business earning $1,500 of qualifying income would normally produce a $300 deduction. The floor lifts that to $400. It only applies to active involvement, though — if a business is really a passive investment someone else runs day to day, the floor isn't available.

The Wider Ranges, in Plain Terms

Above certain income levels, the QBI deduction starts to shrink, and for some service-based businesses — medical, legal, accounting, consulting, financial services, and similar — it can disappear altogether. Where that shrinking starts hasn't moved much, but the range over which it happens got longer: $75,000 for single filers and $150,000 for joint, up from $50,000 and $100,000. In practice, more owners will land somewhere in the middle instead of losing the deduction all at once — and that middle ground is exactly where planning around retirement contributions, the timing of income, and how you're paid through an S corporation can make a real difference.

Why Permanence Matters Most

Since 2018, every conversation about how to structure a business carried an asterisk: this only works if QBI survives past 2025. That asterisk is gone. If your structure was last reviewed with that expiration date in mind, it's worth a fresh look — and that's a conversation for your advisor, not something to decide from an article.

Frequently Asked Questions

Is the QBI deduction permanent now?

Yes. The 20% deduction, previously scheduled to expire after 2025, is now permanent under current law. Entity and compensation decisions no longer need to hedge against a sunset date.

Who qualifies for the $400 minimum deduction

Business owners with at least $1,000 of qualifying income who are actively involved in running that business — not just holding a passive stake. The $400 is indexed for inflation going forward.

Do I need to do anything to claim the $400 minimum?

No separate election — it applies automatically once you qualify. Confirming your involvement counts as "active" rather than passive is the detail worth getting right with your advisor.

I'm in a service business — do the new phase-in ranges help me

Potentially, yes. The range widened to $75,000 (single) and $150,000 (joint), so more service-business owners keep a partial deduction instead of losing it abruptly. Where you land is manageable with timing, retirement contributions, and compensation planning — worth modeling before year-end.
