The "Forever" Tax Break: How the OBBBA Just Changed Small Business Strategy for 2026 and Beyond

For years, small business owners have lived with a "tax cliff" looming on the horizon. The 20% Qualified Business Income (QBI) deduction—a lifeline for S-Corps and LLCs—was supposed to vanish after 2025.

That uncertainty is officially over. With the passing of the One Big Beautiful Bill Act (OBBBA), the tax landscape for entrepreneurs has shifted from "temporary relief" to "permanent strategy." At Lattice Group CPA, we’re helping our clients move past year-to-year survival and into long-term wealth building.

Here are the three biggest "hits" from the OBBBA that you need to know now.

1. The 20% QBI Deduction is Now Permanent

The Section 199A deduction allows eligible business owners to deduct up to 20% of their qualified business income. The OBBBA didn't just save this deduction; it expanded the phase-in thresholds to $75,000 for single filers and $150,000 for joint filers.

• The Strategy: You no longer need to fear an automatic tax hike in 2026. This stability allows for more aggressive reinvestment into your business operations.

2. 100% Bonus Depreciation is Back (and Permanent)

Under previous laws, bonus depreciation was phasing out. The OBBBA has reinstated 100% first-year bonus depreciation for qualified assets acquired and placed in service after January 19, 2025.

• The Strategy: If you’ve been holding off on buying new equipment, vehicles, or technology, the "tax math" just changed in your favor. You can write off the entire cost in Year 1, significantly boosting your immediate cash flow.

3. Immediate R&D Expensing & Retroactive Relief

The OBBBA fixed the "R&D glitch" that forced businesses to amortize domestic research costs over five years. You can now deduct domestic R&D expenses immediately.

• The Catch-Up Opportunity: Small businesses (under $31M in receipts) can potentially apply this retroactively to 2022. This could mean significant refunds for innovation you've already done.

Case Study: S-Corp vs. C-Corp under OBBBA Rules

Choosing the right entity is more critical than ever. Let’s look at a business with $500,000 in net income and $100,000 in new equipment purchases.

Feature	S-Corp (Pass-Through)	C-Corp (21% Flat Rate)
QBI Deduction	$100,000 (20% of $500k)	N/A
Bonus Depreciation	$100,000 (Immediate write-off)	$100,000 (Immediate write-off)
Taxable Income	$300,000 (Taxed at individual rates)	$400,000 (Taxed at 21%)
The "Lattice" Verdict	Best for owners needing cash flow and immediate tax savings.	Better for high-growth tech firms eyeing a $15M QSBS exclusion.

Take Control of Your 2026 Strategy

The OBBBA is a massive win for the "Lattice" style of business—firms that are structured for growth and efficiency. However, permanent laws require more sophisticated planning. It’s no longer about "what can we find at the end of the year," but "how do we structure your entity to maximize these permanent benefits?"
