The QBI Deduction Just Got Permanent. Here's What That Actually Means for You.

The QBI Deduction Just Got Permanent. Here's What That Actually Means for You. For eight years, Section 199A's 20% deduction for pass-through business income carried an expiration date. December 31, 2025 was the scheduled sunset. Every planning decision that depended on the deduction had a hidden asterisk: assuming Congress doesn't let it expire. The One Big Beautiful Budget Act changed that. The QBI deduction is now permanent. The asterisk is gone. That's not just a tax policy update. It's a structural change that affects how self-employed professionals, S-corp owners, and pass-through business owners should think about entity structure, retirement contributions, and long-term tax planning. If your financial plan was built around a sunset that never came, it needs to be rebuilt. Here's what changed, who qualifies, and what it actually means for your planning. What Changed: Section 199A Goes From Temporary to Permanent Section 199A was created by the Tax Cuts and Jobs Act of 2017 as a temporary provision. It allowed eligible pass-through business owners — sole proprietors, single-member LLCs, partnerships, S-corps, and certain trusts — to deduct up to 20% of their qualified business income from federal taxable income. The mechanism is straightforward. If you earn

00,000 in qualified business income from your S-corp or sole proprietorship, you may be able to deduct $40,000, reducing your taxable income to
60,000. You pay income tax on
60,000 instead of
00,000. The deduction doesn't require you to spend money or invest in anything. It's a structural tax reduction on self-employment income. The OBBBA permanently extended this provision under IRC §199A as amended. There is no longer a scheduled expiration date. The deduction is built into the permanent tax code in a way that requires affirmative Congressional action to remove, rather than simply expiring by default. That permanence has compounding implications. Planning decisions that previously had a five-year or shorter payoff horizon now have an indefinite one. Who Qualifies: The Basic Eligibility Rules The deduction applies to qualified business income from: Sole proprietorships (Schedule C) Single-member LLCs taxed as sole proprietors Multi-member LLCs taxed as partnerships S-corporations (the shareholder's pass-through income) Qualified publicly traded partnerships Certain real estate investment trusts W-2 income does not qualify. You have to have pass-through business income. And not all business income qualifies equally — which brings us to the two major limitations. The SSTB phase-out....
