The Qualified Business Income deduction was supposed to die on December 31, 2025. Every pass-through business owner in America — sole props, partnerships, LLCs, S-corps — was staring at a 20% deduction that was about to disappear. If you earn $300,000 through your business, that's a $60,000 deduction gone. At a 24% tax rate, that's $14,400 more in taxes, every year, permanently.
The One Big Beautiful Bill Act made the QBI deduction permanent. But it didn't just extend the old rules — it expanded the phase-out ranges and added a new minimum deduction. Here's what changed and what it means for your 2026 return.
What Stayed the Same
The core structure is unchanged:
- 20% deduction on qualified business income from pass-through entities
- Deducted from taxable income (not AGI) — it's an "above the line" benefit
- Still subject to phase-out for high earners
- Specified service trades or businesses (SSTBs) still face additional restrictions
- W-2 wage and property basis limitations still apply in the phase-out range
If you're familiar with the QBI deduction and your income is comfortably below the phase-out thresholds, the main change for you is simply: it's not going away. You can plan around it permanently.
What Changed: Expanded Phase-Outs
The OBBBA significantly expanded the income ranges where the QBI deduction phases out. This is the change that matters most for mid-to-high-income business owners:
| Threshold | Old Rules (2025) | OBBBA (2026+) |
|---|---|---|
| Full deduction below (Single) | ~$191,950 | ~$200,000 |
| Full deduction below (MFJ) | ~$383,900 | ~$400,000 |
| Phase-out begins (Single) | $100,000 range | $150,000 range |
| Phase-out begins (MFJ) | $100,000 range | $300,000 range |
| Fully phased out (Single) | ~$241,950 | ~$275,000 |
| Fully phased out (MFJ) | ~$433,900 | ~$550,000 |
The expanded ranges mean business owners earning between $200K–$275K (single) or $400K–$550K (MFJ) now get a partial deduction where they previously got nothing or very little. For specified service businesses — law firms, medical practices, consulting firms, accounting firms — this is especially significant.
Real Dollar Example: SSTB Owner at $280K
Meet Sarah, a solo consultant filing single with $280,000 in taxable income. Her business is classified as a specified service trade or business (SSTB). Under the old rules, her QBI deduction was fully phased out at her income level. Under the OBBBA:
Sarah's income of $280,000 is now within the expanded phase-out range ($200K–$275K for single filers) rather than fully phased out. Because she's near the upper end, she gets a partial deduction — roughly 66% of the full 20%. On $280,000 of QBI, that's approximately $37,300 in deductions and about $8,950 in tax savings she didn't have before.
For a married couple filing jointly with $480,000 in combined business income, the math is even more dramatic — they move from fully phased out to a substantial partial deduction worth $15,000–$20,000 in annual tax savings.
Note on the 20% rate: You may have seen references to a "23% QBI deduction" in early OBBBA coverage. The final legislation kept the rate at 20%. The 23% proposal did not make it into the enacted law.
The New $400 Minimum Deduction
The OBBBA introduced a new floor: anyone with at least $1,000 in qualified business income who materially participates in the business gets a minimum QBI deduction of $400. This isn't going to change anyone's life, but it ensures that very small business owners and side-business operators get at least some benefit from the provision.
SSTB Phase-In: What Service Businesses Need to Know
Specified service trades or businesses — the category that includes lawyers, doctors, consultants, accountants, financial advisors, and performing artists — face additional restrictions on the QBI deduction. Under the old rules, SSTBs started losing their deduction quickly and lost it entirely at relatively modest income levels.
The OBBBA expanded the SSTB phase-in ranges along with the general phase-out ranges. This means service business owners at moderate income levels (the $200K–$275K single / $400K–$550K MFJ range) who previously got zero deduction now get a partial one.
If you've been told "you make too much to qualify for QBI" and you're an SSTB, check again under the new rules. The math may have changed in your favor.
The QBI deduction is permanent — but the rules are more complex than ever. If you're a pass-through business owner earning $150K+, let's make sure you're maximizing your deduction under the new thresholds.

With the QBI deduction now permanent and the phase-out ranges wider, taxable income management becomes even more valuable. Every dollar of taxable income you can shift below a threshold increases your QBI deduction. Strategies to consider:
- Retirement contributions: Maximizing 401(k), SEP-IRA, or defined benefit plan contributions reduces taxable income directly
- S-corp salary optimization: If you're an S-corp owner, your reasonable salary doesn't count as QBI — but it reduces taxable income for phase-out purposes. The balance matters.
- Timing deductions: Accelerating equipment purchases into high-income years using Section 179 or bonus depreciation can push taxable income below QBI thresholds
- Entity structuring: Some multi-business owners can structure entities to separate SSTB income from non-SSTB income, maximizing the deduction on the non-service business
QBI + S-Corp: The Interaction That Matters
If you operate as an S-corp, the QBI deduction interacts with your reasonable salary in an important way. Your W-2 salary from the S-corp is not qualified business income — only the pass-through profit (distributions) qualifies for the 20% deduction.
This creates a planning tension: a lower salary means more QBI (bigger deduction), but it also means potential IRS scrutiny on reasonable compensation. The optimal balance depends on your total income, your phase-out position, and your self-employment tax exposure. It's exactly the kind of calculation where a proactive tax strategy pays for itself many times over.
The Permanence Factor
The biggest practical change isn't in the numbers — it's in the certainty. When the QBI deduction had a 2025 expiration date, long-term planning was impossible. Should you restructure your business around QBI? Invest in strategies to maximize it? You couldn't know if it would exist in two years.
Now you can plan around it permanently. The 20% QBI deduction is a structural part of the tax code. That changes how you think about entity selection, income timing, retirement planning, and compensation strategy — not just for this year, but for the life of your business.
