## What’s Shifting for Entities in the OBBB Era
Recent U.S. tax law changes under the *One, Big, Beautiful Bill* include:
- **Excess compensation rules** for tax-exempt entities—including nonprofits—are being addressed with proposed regulations. ([irs.gov](https://www.irs.gov/newsroom/news-releases-for-current-month?utm_source=openai))
- **Qualified business income deduction (QBID)** made permanent, plus new floors and thresholds for minimal qualified income, increasing opportunities for many small and pass-through businesses. ([irs.gov](https://www.irs.gov/pub/irs-prior/p505--2026.pdf?utm_source=openai))
- **Opportunity Zones (QOZs)** guidance updated: rural tracts eligible, new nomination rounds starting July 1, 2026.

## LLC vs S-Corp vs C-Corp: Key Criteria & Tax Effects
| Structure | Tax Treatment | Pros | Cons |
|---|---|---|---|
| **LLC (single-member / multi)** | Pass-through; profits taxed on owner’s personal return; owners subject to self-employment tax for earned profits. | Simple setup, flexible, fewer formalities, full pass-through of losses. | Self-employment tax, limited benefit for reinvested profits; state tax variances. |
| **S-Corp** | Pass-through; wages + distributions; avoid self-employment tax on distribution portion. | Potential savings on self-employment taxes; some structure allows deferred income. | Must meet eligibility; more formalities; IRS scrutiny on “reasonable salary”. |
| **C-Corp** | Entity taxed separately; profits taxed at corporate rate; dividends taxed to shareholders. | Lower corporate rates (depending on income), retained earnings; possible state benefits. | Double taxation of dividends; formalities; less favorable for small business distributions. |
## Tips Post-OBBB
- If you’re using pass-through, consider the QBID changes: with the permanent QBID now allowing a **minimum claim of $400** if you have at least $1,000 of qualified income, and phase-in thresholds widened—make sure your income and entity structure qualifies. ([irs.gov](https://www.irs.gov/pub/irs-prior/p505--2026.pdf?utm_source=openai))
- Nonprofits need to review the **proposed regulations** on excess compensation and parachute payments under OBBB—as potential increases in tax liability can hit poorly governed organizations. ([irs.gov](https://www.irs.gov/newsroom/news-releases-for-current-month?utm_source=openai))
- Opportunity Zone investment: if your business plans to invest or develop in QOZs, especially rural tracts eligible under new guidance, structure to maximize benefits. LLCs or C-Corps used to hold QOZ property may leverage deferral and gain exclusion, but must comply with substantial improvement and other criteria.

## Actionable Steps For Entrepreneurs & New Entities
1. Write out your expected income, margins, growth rate. Higher reinvestment and growth may favor a C-Corp; steady distributions may be better as S-Corp or LLC.
2. Factor in self-employment tax savings when using S-Corp vs LLC.
3. Keep excellent records of salaries and distributions if you’re an S-Corp, to satisfy “reasonable compensation” rules especially as IRS oversight intensifies.
4. Use state law counsel—in Delaware, Nevada, or your home state—as entity law (filing fees, formalities, state taxation) can erode federal tax savings.
5. Revisit your structure each year: changes in tax laws like those under OBBB may shift what’s optimal over time.
## Case Study: Small Business Scenario
_Scenario_: Beta Creative, net profits $200,000/year. Owner could take $100,000 salary + $100,000 in distributions in S-Corp form vs entire income in LLC.
- As S-Corp: wage taxed for payroll + income tax; distributions avoid self-employment tax. May save ~15% on FICA/Medicare portion.
- As LLC: Entire $200,000 subject to self-employment tax (~15.3%) plus income tax—costly.
- Incorporation costs + payroll setup may offset initial savings—run numbers.
## Summary
Choosing the right entity type in 2026 requires weighing tax liabilities, administrative costs, and your cash flow patterns. With OBBB changes to deductions, safe harbors, and compensation rules, what was optimal last year may not be now. Evaluate often, keep good records, and don’t hesitate to get professional help if your business or income scales up.
