One of the most common questions I hear during tax consultations is this:
“So… which business structure is actually best for me?”
Whenever major tax reform proposals surface—especially something as sweeping as the Build Back Better (BBB) Act)—that question becomes even more urgent. Business owners who already operate as LLCs or S-Corporations often feel a renewed sense of uncertainty.
Just recently, I had a long conversation with a business owner who had converted to an S-Corp a few years ago for tax savings. After hearing the latest news about potential tax law changes, he wondered whether he should switch back to a C-Corp or a standard LLC.
Here’s the bottom line:
There is no one-size-fits-all answer.
The right structure depends on your business size, profit level, and how you take money out of the business.
What is universal, however, is this:
Changing your structure without understanding the direction of tax law changes can create more harm than benefit.
1. BBB Act and Corporate Tax Rates: Why Business Owners Are Nervous Again
After the Tax Cuts and Jobs Act (TCJA) under the Trump administration, corporate tax rates were set at a flat 21%, making C-Corps attractive again for many business owners.
However, the core philosophy behind the BBB Act is different. Its focus is on:
-
Increasing taxes on higher-income individuals
-
Raising taxes on larger corporations
If corporate tax rates increase again, the assumption that
“Corporations are always taxed less”
may no longer hold true.
This is especially important for small business owners who:
-
Do not retain earnings in the company, and
-
Take most profits out as salary or dividends
In these cases, double taxation—once at the corporate level and again at the individual level—can significantly reduce after-tax income.
2. Is the S-Corp Tax Strategy Still Effective?
The biggest advantage of an S-Corporation remains clear:
✔ Reduction of Self-Employment Tax
Income taken as distributions (not wages) is not subject to Social Security and Medicare taxes, which can lead to substantial savings.
That said, one key issue to watch under the BBB Act is the potential expansion of the Net Investment Income Tax (NIIT) for high-income taxpayers.
If S-Corp distributions become more broadly subject to NIIT:
-
The tax savings may be smaller than before
-
High-income owners may see less dramatic benefits
Even so, the core S-Corp strategy still holds:
Pay yourself a reasonable salary, and minimize payroll taxes on remaining profits.
For many small and mid-sized businesses, this remains the most practical structure.
What has changed is the need for precision. It’s no longer enough to assume S-Corp = savings. You now need to calculate:
-
Which tax brackets your income falls into
-
Whether NIIT applies to your distributions
3. The Real Strength of an LLC: Flexibility
In times of tax law uncertainty, LLCs may actually be the most resilient option.
I still strongly recommend LLCs for:
-
Solo entrepreneurs
-
Freelancers and consultants
-
Knowledge-based service providers
-
Businesses with fluctuating income
Why LLCs Remain Powerful
-
Default pass-through taxation
-
The ability to elect S-Corp or C-Corp status later
That flexibility is a major asset when tax laws are in flux. It allows you to adapt without dismantling your entire business structure.
A Practical Word of Advice from a Tax Professional
Tax laws change.
Your business fundamentals usually don’t.
Reacting out of fear to proposed legislation—by rushing into or out of a corporate structure—can easily backfire and increase your tax burden.
What You Should Do Right Now
-
Estimate your expected net income for this year and the next 1–2 years
-
Determine whether upcoming tax changes primarily affect:
-
Corporate tax rates, or
-
High-income individuals
-
Then, place yourself clearly within that framework.
Taxes aren’t minimized by what you “know”—they’re protected by what you prepare for.
As we move into the post-2025 tax landscape, now is the right time to reassess whether your current business structure is acting as a shield—or a risk.
