The New 23% QBI Deduction in the One Big Beautiful Bill: What Every Small Business Owner Needs to Know

Overview: A Defining Moment for Small Business Owners

‍

With the narrowly passed One Big Beautiful Bill (OBBB or “Big Beautiful Bill”), Congress has confirmed a permanent increase in the Qualified Business Income (QBI) deduction—from 20 percent to 23 percent for pass-through entities. Rooted in Section 199A of the tax code, this deduction is now cemented for the long term, replacing the fading expiration of 2025—and it reshapes how small business owners approach taxes, planning, and reinvestment.

‍

This update was widely celebrated by organizations like the NFIB, which hailed it as “one of the most pro-small business pieces of legislation in recent history” (See NFIB artcile).

‍

I. What’s Changed—and Why It’s Important

‍

1. Deduction Rises from 20% to 23%

‍

The core benefit is straightforward: eligible pass-through entities—sole proprietorships, partnerships, S-corporations, and LLCs—may now deduct 23 percent of their qualified business income instead of the prior 20 percent . This effectively lowers the marginal tax rate on QBI to approximately 28.49 percent, down from 29.6 percent (See Barron's Article).

‍

2. Perpetual Extension

‍

Originally scheduled to sunset after December 31, 2025, the deduction is now permanent—removing uncertainty and enabling strategic, multi-year financial planning bipc.com. The Tax Foundation confirms this change starts in 2026 (See the Tax Foundation Article).

‍

3. New Phase-Out Mechanism

‍

High earners faced sharp cliff effects under previous rules. The updated legislation smooths the reduction: for incomes above threshold, the deduction phases out at 75 cents per $1 of excess income, rather than disappearing abruptly . This nuance means more predictability and less surprise at tax time.

‍

4. Expanded Eligibility to BDC Dividends

Previously, only REIT and publicly traded partnership dividends were included. The Bill expands QBI to include net interest income from BDC (Business Development Company) dividends, enhancing after-tax yields for investors in credit-centered vehicles (See Tax Talks article)

‍

II. Why These Changes Matter

‍

💡 1. Immediate Tax Savings

‍

Even modest QBI earners benefit. For instance, business income of $150,000 sees:

‍

• Old deduction (20%): $30,000 → tax break at bracket
• New deduction (23%): $34,500 → deeper deduction
• Additional savings: $4,500 × estimated 32% bracket = $1,440

‍

Scaled up, higher incomes yield significantly larger savings. These are real dollars that could be reinvested in staff, tech, or growth initiatives.

‍

💡 2. Certainty in Business Planning

‍

Permanent tax enhancements foster confidence. Small business owners can more precisely forecast cash flows and budgets through 2030 and beyond—essential in a landscape where temporary provisions used to pressure leaders into short-term decisions.

‍

💡 3. Broader Access and Smoother Cliffs

‍

By shifting the phase-out from abrupt to gradual, more small businesses, including SSTBs (Specified Service Trades or Businesses), will tap into the deduction. BDC dividend inclusion further extends reach—especially beneficial to diversified owners of finance or credit investments See Nat Law Review Article).

IV. The Bigger Fiscal Picture: Calls to Caution

‍

While applauding tax savings, analysts at the CBO and budget watchdogs warn that the overall bill shifts significant resources upward, inflates the deficit, and shrinks social safety networks (See wsj.com):

‍

• CBO estimates the bill will increase deficits by $2.4T–$2.6T over a decade wsj.com.
• Meanwhile, cuts in Medicaid, SNAP, and assorted public programs could offset but may harm vulnerable populations (see Wash Post)
• Economists suggest that tax cuts alone may stimulate growth only temporarily, failing to offset long-term debt impacts (wsj.com).

‍

A wave of Senate amendments and vocal criticism from figures like Elon Musk reflect concern that the bill’s broader cost could undercut benefits (nypost.com).

‍

V. What Small Businesses Should Do Now

‍

1. Verify Your Eligibility
   Confirm your business is a qualifying pass-through. If you earn dividends from BDCs that are net-interest-based, this is critical.
2. Plan for 2026 and Beyond
   Use the permanent deduction to model future cash flows, financing, and expansion.
3. Collaborate With Tax Advisors
   Confirm correct phase-out application, understand the two-step deduction formula, and monitor taxable thresholds.
4. Consider Investing in BDCs
   With enhanced QBI inclusion, certain BDCs may offer more attractive after-tax returns—especially if you’re income-positioned to benefit.
5. Review Holistically
   Other provisions—bonus depreciation, interest deductions, estate exemptions—may feed off QBI changes. Holistic planning is essential.

‍

VI. Looking Ahead: Risk vs. Reward

‍

This policy is transformative for small business owners—but not immune to future changes:

‍

• Senate revisions could tweak this provision before final enactment.
• Future legislation may impact offsetting cuts or reduce benefits.
• Economic conditions like interest rates and inflation may alter the relative value of the 23% deduction.

‍

Despite potential volatility, the fact this deduction is permanent and improved marks a structural shift, enabling long-term optimism and informed investment in the Main Street economy.

‍

VII. Conclusion

‍

The permanent elevation of the QBI deduction to 23% in the One Big Beautiful Bill is more than a tax headline—it’s a watershed moment for entrepreneurship and ownership. The expanded, long-lasting nature of this tax incentive gives small business owners a foundation of financial clarity and stability. Whether you're reinvesting in staff, equipment, or expansion, this newfound certainty empowers Main Street to plan, grow, and thrive.
