## Tax Law Landscape Changes You Can’t Ignore
Recent legislation under the **One, Big, Beautiful Bill** (OBBB) has **reshaped federal tax policy** significantly. Important updates include raised **standard deductions**, changed tax rate brackets, new deductions (tips, overtime), and enhancements for seniors and families—all of which influence your choice of business entity.

When choosing between being an **LLC taxed as a sole proprietor or partnership**, an **S-corporation**, or a **C-corporation**, several changes matter:
- The size of **standard deductions** may reduce benefits of being a sole prop if your personal income is low vs income retained in a corporation. The standard deduction for married filing jointly is now **$32,200** for 2026 under OBBB. ([irs.gov](https://www.irs.gov/newsroom/irs-releases-tax-inflation-adjustments-for-tax-year-2026-including-amendments-from-the-one-big-beautiful-bill?utm_source=openai)).
- **Marginal tax rates** shift the break-points for pass-through entities vs C-corps. OBBB retains the top 37% bracket, but income ranges are elevated. ([irs.gov](https://www.irs.gov/newsroom/working-families-tax-cuts-individuals-and-workers?utm_source=openai)).
## Case Study: Sarah’s Graphics Studio
Sarah is a graphic designer expecting **$500,000 net income** this year. She is married filing jointly with her spouse involved minimally in the business.
| Business Structure | Key Tax Impacts Under OBBB | Pros & Cons for Sarah |
|---------------------|-----------------------------|------------------------|
| **Sole Proprietorship / LLC** | Income flows directly into her personal return; full standard deduction; new deductions (tips may not apply) | Pros: simplicity, full access to enhanced deductions. Cons: higher self-employment tax; bracket creep when combined with spouse’s income. |
| **S-Corporation** | Can pay herself a salary and take distributions; payroll taxes on salary; distribution income taxed via ordinary rates post-salary; access to business deductions | Pros: reduce self-employment taxes; limited liability; keep standard deduction. Cons: administrative cost; balancing salary vs distributions matters now more with new rate brackets. |
| **C-Corporation** | Taxed at flat corporate rate; after distribution, dividends taxed to shareholders; possible double taxation but certain optimized strategies (e.g., retaining earnings, benefits) | Pros: retained earnings could stay taxed at corporate level if low; may help if reinvesting; cons: corporate + dividend tax could be higher. |
## Action Steps When Setting Up or Restructuring
- **Run forecasts**: Estimate both business and personal income under each structure using the current rates and deductions. Then see which gives you better after-tax income.
- **Consider employee/shareholder split**: If using S-corp or LLC electing S, paying yourself a “reasonable salary” may shift you into different brackets—optimize distributions accordingly.
- **Factor in retirement plan contributions and credits**: For C-corps, you may have different options; individuals benefit from raised contribution limits.
- **Think about future plans**: If you plan to scale, add partners, raise capital, or exit—C-corporation status may attract investors better, but tax efficiency might favor pass-through initially.
## Example Outcome for Sarah
After modeling figures, Sarah realized that electing an **S-corporation** will allow her to take advantage of her standard deduction, reduce self-employment taxes, but still keep most income taxed at beneficial rates under OBBB’s increased brackets. Retained earnings in C-corp would have been taxed twice once dividends are distributed, making it less favorable given her high personal income.
**Bottom line**: OBBB changes make structuring decisions more impactful. Model your numbers, align with long-term goals, and choose the structure that optimizes taxes *and* operations.
